```
editTextUsername = EditText findViewById(R.id.email_edittext)
```
and the error is :
Error:(70, 35) Unexpected tokens (use ';' to separate expressions on the same line)
but i can not understand what did i do wrong.<issue_comment>username_1: If you're trying to specify the type of a variable, you can do it like this:
```
val editTextUsername: EditText = findViewById(R.id.email_edittext)
```
If you're below API level 26, and need a cast:
```
editTextUsername = findViewById(R.id.email_edittext) as EditText
```
If you already have the generic `findViewById` method because you're on a newer API level:
```
editTextUsername = findViewById(R.id.email\_edittext)
```

```
editTextUserName = findViewById(R.id.) as EditText
```
or inside fragment use the ff
```
View view = inflater.inflate(R.layout.article_view, container, false);
editTextUserName = view.findViewById(R.id.) as EditText

```
def test():

map['a']()

def func2(): pass

```
func = getattr(self, analysis['func'])
analysis['data'] = func(required_cols[0], required_cols[1], agg, col_name)

Essentially:
Find the top 2 TotalPrice in descending order.
Of those 2, find the top TotalPrice in ascending order.
The selected value is the second-highest TotalPrice.
If the TotalPrice isn't distinct, you can use `SELECT DISTINCT TOP ...` instead.

When I place the ng-template within the same HTML where I use it works but when I move ng-template into a separate file then it won't work. Is there a way to move ng-template into its own file and use it in different html file?
**info-message.html**

Hi

above is working fine because ng-template and the usage is in same file
**message-template.html**
```
Hi

```
This is not working. Is there a way to use **"messageTemplate"** which is in a separate file inside another html(Eg: info-message.html)
Thanks in advance.<issue_comment>username_1: You can use something like this (template is used from another component):
```
@Component(
template: ''
)
export class MessageTemplate {
infoMessage: InfoMessage;
}
@Component(
....
)
export class InfoMessage{
@ContentChild('columnTemplate') template: TemplateRef;
constructor(private messageTemplate: MessageTemplate) {
messageTemplate.infoMessage = this;
}
}
```

The suggestion is that if you want to reuse your template in different files, you should convert what is inside the template into a separate component, then you can reuse that component wherever you want.
Upvotes: 2 <issue_comment>username_3: This behaviour can be achieved via a 'portal'. This is a useful and fairly common pattern in Angular applications. For example you may have a global sidebar outlet living near the top app level and then child components may specify a local , as part of their overall template, to be rendered at this location.
Note that while the may be defined outside of the file where the desired outlet is defined, it is still necessary to place the inside the template of *some* component. This can be a minimalist component which is only responsible for wrapping the , however it could equally be a complicated component where the of interest only plays a minor part.
This code illustrates one possible basic implementation of a portal.
```
@Directive({
selector: '[appPortal]'
})
export class PortalDirective implements AfterViewInit {
@Input() outlet: string;
constructor(private portalService: PortalService, private templateRef: TemplateRef) {}
ngAfterViewInit(): void {
const outlet: PortalOutletDirective = this.portalService.outlets[this.outlet];
outlet.viewContainerRef.clear();
outlet.viewContainerRef.createEmbeddedView(this.templateRef);
}
}
@Directive({
selector: '[appPortalOutlet]'
})
export class PortalOutletDirective implements OnInit {
@Input() appPortalOutlet: string;
constructor(private portalService: PortalService, public viewContainerRef: ViewContainerRef) {}
ngOnInit(): void {
this.portalService.registerOutlet(this);
}
}
@Injectable({
providedIn: 'root'
})
export class PortalService {
outlets = new Map();
registerOutlet(outlet: PortalOutletDirective) {
this.outlets[outlet.appPortalOutlet] = outlet;
}
}
```
It works using three parts:
* A 'portal' directive. This lives on the desired and takes as input the name of the outlet at which the content should be rendered.
* A 'portal outlet' directive. This lives on an outlet, e.g. an , and defines the outlet.
* A 'portal' service. This is provided at the root level and stores references to the portal outlets so they can be accessed by the portals.
This may seem like a lot of work for something quite simple but once this plumbing is in place it is easy to (re)use.
```
// foo.component.html
Foo

RIGHT

```
In general it's not a great idea to reinvent the wheel though when there are already well-tested, documented and stable implementations available. The [Angular CDK](https://material.angular.io/cdk) provides [such an implementation](https://material.angular.io/cdk/portal) and I'd advise to use that one rather than your own in practice.

**To use:**
```
'app.module.ts'
```
```js
import {NgModule} from '@angular/core';
import {
IdcPortalDirective, IdcTemplatePortalDirective,
PortalService
} from './idc-template-portal/idc-template-portal.component';
@NgModule({
declarations: [
IdcPortalDirective,
IdcTemplatePortalDirective
],
imports: [],

providers: [
PortalService
],
bootstrap: [AppComponent]
})
export class AppModule {}
```
```
'./idc-template-portal/idc-template-portal.component.ts'
```
```js
import {
AfterViewInit,
Directive,
Injectable,
Input,
OnInit, Output,
TemplateRef,
ViewContainerRef
} from '@angular/core';
/*** Input Template ***/
/*** Template Contents ***/
@Directive({
selector: '[idcPortal]'
})
export class IdcPortalDirective implements OnInit {
@Input() outlet: string;
@Output() inlet: string = this.outlet;
constructor(private portalService: PortalService, public templateRef: TemplateRef) {}
ngOnInit():void {
this.portalService.registerInlet(this);
}
}
/\*\*\* Output Container \*\*\*/
/\*\*\* \*\*\*/
@Directive({
selector: '[idcPortalOutlet]'
})
export class IdcTemplatePortalDirective implements OnInit, AfterViewInit {
@Input() appPortalOutlet: string;
@Output() outlet: string = this.appPortalOutlet;
constructor(private portalService: PortalService, public viewContainerRef: ViewContainerRef) {}
ngOnInit():void {
this.portalService.registerOutlet(this);
}
ngAfterViewInit() {
this.portalService.initializePortal(this.appPortalOutlet);
}
}
@Injectable({
providedIn: 'root'
})
export class PortalService {
outlets = new Map();
inlets = new Map();
registerOutlet(outlet: IdcTemplatePortalDirective) {
this.outlets[outlet.outlet] = outlet;
}
registerInlet(inlet: IdcPortalDirective) {
this.inlets[inlet.inlet] = inlet;
}
initializePortal(portal:string) {
const inlet: IdcPortalDirective = this.inlets[portal];
const outlet: IdcTemplatePortalDirective = this.outlets[portal];
outlet.viewContainerRef.clear();
outlet.viewContainerRef.createEmbeddedView(inlet.templateRef);
}
}
```
He,@username_3, mentions reinventing the wheel in regards to the [Angular CDK portals package](https://material.angular.io/cdk/portal/overview). However, I find his/this implementation to make more sense in the way it's used in the application flow and the ease in which a template can be ported from component to another component that contains the portal outlet (allowing component to component->portal template communication. For example within a component template implementing the [Angular Material MatBottomSheet](https://material.angular.io/components/bottom-sheet/overview) (idcBottomSheet)).

A place for your thoughts:

**The 'output' element (inside your MatBottomSheet component template):**

Unfortunately I get an error:

For example you can instead place your `*ngFor` in a and wrap it around your `-` element. The advantage of is the fact, that it doesn't introduce extra levels of HTML.
```js

Example 1
```

or
Example 2

2018/03/21 | 1,050 | 3,347 | <issue_start>username_0: Okay, let met explain. I am getting a obsersable from AngularFire Database, and here is what I pretend to do:
- get 2 static copies of the obsersable response
- show 1 static copy
- allow user to modify this static copy and not save it
- when user decides too cancel the changes, i simply get the copy number 2 and set it to copy number 1.
getting obsersable:
```
this.afoDatabase.object("usuarios/"+this.userKey+"/pacientes/"+this.pacienteKey).map(res=> {
this.model = res;
this.model2 = res;
}).first().toPromise();
```
when the users decides to cancel the changes, here is what i am doing:
```
this.model = this.model2;
// this.model is the copy number 1 and this.model2 is the 'unchanged' copy number 2
```
but when i do it, the copy number 2, even that i never showed or changed it, is exactly equal to copy number 1;<issue_comment>username_1: Map is used to modify data received in each event.
So you need to assign data to model like
```
.first((data) => model = data)
```
Then use
```
.subscribe((data) => model2 = data)
```
If you want to modify data format you may call
```
.map((data) => { let res = modifyData(data); return res});
```
Update:
```
import { timer } from 'rxjs/observable/timer';
import 'rxjs/add/operator/first';
let model, model1;
let observable = timer(0, 1000);
observable.first().subscribe((n) => {
model = n;
});
observable.subscribe((n) => {
model1 = n;
});
```
Upvotes: 0 <issue_comment>username_2: **Updated**
You can use [combineLatest](https://www.learnrxjs.io/operators/combination/combinelatest.html) like
```
let supplier = this.afoDatabase.object("usuarios/" + this.userKey + "/pacientes/" + this.pacienteKey);
Observable.combineLatest(supplier, supplier)
.map([model1, model2]=> {
this.model1=model1;
this.model2=model2;
}).first()
...
```
CombineLatest will emit an array when both of these observables emits. Here `model1` and `model2` should have same value.
*Note*: This will create two separate requests. If you want to create single request then look below at Previous Answer.
**Previous Answer**
Look here
```js
let res = {foo:1,bar:2}
let model1 = res;
let model2 = res;
model1.foo=3;
console.log(model1.foo) //3
console.log(model2.foo) //3
```
Because when we declare `model1` and `model2` with value `res`, so both points to the same object. Both holds the reference of same object (here `res`) and changing one changes other.
What you need to do is clone `res` to `model2` so it will a different object with same value as `res`. Cloning is of two types shallow and deep.
1. [Efficient deep copy](https://stackoverflow.com/questions/122102/what-is-the-most-efficient-way-to-deep-clone-an-object-in-javascript?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa)
2. [Shallow copy](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/assign)
3. [Difference between shallow and deep copy.](https://stackoverflow.com/questions/184710/what-is-the-difference-between-a-deep-copy-and-a-shallow-copy)
If your `res` objects values are string, numbers etc then you need shallow copy. Example
```
res= {a:1,b:"2"}
```
If they contains array, other objects then you need deep copy. Example
```
res={a:{c:1},b:[2,3]}

```
SELECT 10 as price
UNION ALL
SELECT ('{"price":2}'::jsonb->>'price')::int as price
```
Upvotes: 3 [selected_answer]<issue_comment>username_2: The `->` operator returns a JSONB value, not an integer. You need to use the `->>` operator which returns a `text` and then cast that to an integer:
```
SELECT 10 as price
UNION ALL
SELECT ('{"price":2}'::jsonb->>'price')::int as price;

2018/03/21 | 892 | 3,191 | <issue_start>username_0: I am wondering how to configure the `.npmrc` file so that I can have a default registry and a different scoped registry with authentication.
I am using Nexus for the private repository and I am not sure how to set authentication for the scoped registry, only the default registry.
For example my `~/.npmrc` file is:
```
registry=https://registry.npmjs.org/
@test-scope:registry=http://nexus:8081/nexus/content/repositories/npm-test/
email=<EMAIL>
_auth="…"
```
If I do `npm publish` for a package scoped to `test-scope`, I get an authentication error.
AFAIK, the `_auth` only applies to the `registry=...` section. Is there a way of specifying an auth key for the `@test-scope:registry=...` section?
Thanks,<issue_comment>username_1: So, after some digging through the NPM source code, it turns out there is a way to do this.
My solution is below:
```
registry=https://registry.npmjs.org/
@test-scope:registry=http://nexus:8081/nexus/content/repositories/npm-test/
//nexus:8081/nexus/content/repositories/npm-test/:username=admin
//nexus:8081/nexus/content/repositories/npm-test/:_password=<PASSWORD>M=
email=…
```
**Explanation:**
The scope `@test-scope` specifies that packages with the scope should be published to a different registry than the default `registry=` when executing the `npm publish` command.
The two lines starting with `//nexus:8081/...` are used to specify the credentials to the scoped repository for both `username` and `_password` where `_password` is the base64 encoded password component from the previously used `_auth` credentials.
Using this approach, only scoped packages will be published and installed from the private registry and all other packages will be installed from the default registry.
**Edit:**
Additional to this, the password can be specified as an environment variable so that it is not stored in plaintext in the file.
For example:
```
registry=https://registry.npmjs.org/
@test-scope:registry=http://nexus:8081/nexus/content/repositories/npm-test/
//nexus:8081/nexus/content/repositories/npm-test/:username=admin
//nexus:8081/nexus/content/repositories/npm-test/:_password=${<PASSWORD>}
email=…
```
Also, when using Nexus, the `email=` line must be specified.
Upvotes: 7 [selected_answer]<issue_comment>username_2: for some strange reason the `_auth` is called `_authToken` when used with scoped packages. If you are using this you don't have to store your plain text password in your `.npmrc`
```
registry=https://registry.npmjs.org/
@test-scope:registry=http://nexus:8081/nexus/content/repositories/npm-test/
//nexus:8081/nexus/content/repositories/npm-test/:_authToken=...
email=…
```

```

The below assumes there will always be the same number of lvcontainer and rvcontainer
```js
var lvcontainer = document.getElementsByClassName('lvcontainer');
var rvcontainer = document.getElementsByClassName('rvcontainer');
for (i = 0; i < lvcontainer.length; i++) { // loop to the length
(function(protectedIndex) { // protect the index so clicks won't use last increment of i
// show
lvcontainer[protectedIndex].addEventListener("mouseover", function() {
rvcontainer[protectedIndex].style.display = "block";
}, false);
// hide
lvcontainer[protectedIndex].addEventListener("mouseout", function() {
rvcontainer[protectedIndex].style.display = "none";
}, false);
})(i);
}
```
```css
body {
margin: auto;
}
#container {
display: table;
}
#lcontainer {
padding: 0 10px 0 10px;
display: table-cell;
}
#rcontainer {
padding: 0 10px 0 10px;
display: table-cell;
}
.rvcontainer {
display: none;
}
```
```html

After your comment, I would restructure your html to be a bit more semantically correct:
```css
#container ul {
margin: 0;
padding: 0;
list-style: none;
}
#lcontainer {
display: inline-block;
position: relative;
}
.lvcontainer {
padding: 0.1em 0.5em 0.1em 0.1em;
}
.rvcontainer {
display: none;
position: absolute;
top: 0;
left: 100%;
}
.lvcontainer:hover>.rvcontainer {
display: block;
}
```
```html
* Country

```
const getMenu = filter => (
);
this.handleDropdownVisibility(val, searchFilter)
}

```
Here is my MenuContainer which return Select Component inside it
```
handleSelectChange = val => {
this.setState({
selectedValue: val,
});
};
{numberComparision.map((item, i) => {
return (

})}
```
so on clicking select value onVisibleChange fires and closes dropdown
[](https://i.stack.imgur.com/9mC9n.png)<issue_comment>username_1: You are mixing components that are not meant to be mixed here, I believe.
Dropdown expects its overlay to be a menu of some sorts. Or at least something static that does not open yet another dynamic layer.
Select already has a dropdown type behaviour. So your Dropdown opens the Select which opens the Select dropdown, and then they both react to the click event and close.
It is currently not clear from your question and screenshot what you are actually trying to achieve, that could not be achieved using just a Select. You could try clarifying that.
Upvotes: 0 <issue_comment>username_2: In current v3.3.1 there is no API to prevent to close the `Dropdown` list.
As a solution I can offer **[this custom component](https://codesandbox.io/s/71ll81l72q)**.
[](https://i.stack.imgur.com/kMrLP.png)
`Item` has a property `clickable` which indicates will be the droplist closed after click or not. You can set `true/false` or css name of an element which should not trigger closing drop-list.
Upvotes: 1 <issue_comment>username_3: Change Menu.Item where the select is contained to a Menu.ItemGroup, those do not trigger the onVisibleChange when clicked.

2018/03/21 | 1,367 | 5,054 | <issue_start>username_0: i have a simple Selenium Test Code:
```
public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver", "/home/chromedriver");
WebDriver driver= new ChromeDriver();
driver.get("http://google.com");
}
```
And i get this Error:
```
Exception in thread "main" java.lang.NoClassDefFoundError: okhttp3/ConnectionPool | Caused by: java.lang.ClassNotFoundException: okhttp3.ConnectionPool
```
I think the jars and Dependency are ok but i still get this Error<issue_comment>username_1: The error says it all :
```
Exception in thread "main" java.lang.NoClassDefFoundError: okhttp3/ConnectionPool | Caused by: java.lang.ClassNotFoundException: okhttp3.ConnectionPool
```
What is **`NoClassDefFoundError`**
----------------------------------
**`NoClassDefFoundError`** in Java occurs when **`Java Virtual Machine`** is not able to find a particular class at runtime which was available at compile time. For example, if we have resolved a method call from a class or accessing any static member of a Class and that Class is not available during run-time then **`JVM`** will throw **`NoClassDefFoundError`**.
The error clearly says that you have misconfigured the **classpath**. It would be tough to debug the exact cause of the issue untill and unless you tell us how you run tests, which builder or IDE do you use and the builder config file or project description.
What went wrong :
-----------------
From all the above mentioned points it's clear that the related **`Class`** or **`Methods`** were resolved from one source **`Compile Time`** which was not available during **`Run Time`**.
This situation occurs if there are presence of multiple sources to resolve the Classes and Methods through **`JDK`**/**`Maven`**/**`Gradle`**.
Selenium dependency on okhttp
-----------------------------
At this point it is worth to mention that **selenium-java-3.9.x** clients does have a dependency on **okhttp** and you can find the [dependency list here](http://search.maven.org/#artifactdetails%7Corg.seleniumhq.selenium%7Cselenium-java%7C3.11.0%7Cjar).
It is also to be noted that :
* There were some issues with launching of Chrome as per [Can't launch chrome browser using latest selenium 3.9.0](https://github.com/SeleniumHQ/selenium/issues/5453).
* To address the issue from *Selenium v3.9.1* **OkHttp backed instances can now connect to servers requiring authorisation** which was based on PR [#5444](https://github.com/SeleniumHQ/selenium/pull/5444).
Solution :
----------
Here are a few steps to solve **`NoClassDefFoundError - okhttp3/ConnectionPool`** error :
* While using a Build Tool e.g. **`Maven`** or **`Gradle`**, **remove** all the **`External JARs`** from the **`Java Build Path`**. **`Maven`** or **`Gradle`** will download and resolve all the required dependencies.
* If using **`Selenium JARs`** within a **`Java Project`** add only required **`External JARs`** within the **`Java Build Path`** and remove the unused one.
* While using **`Maven`**, either use **`selenium-java`** or **`selenium-server`**. Avoid using both at the same time.
* Upgrade *JDK* to recent levels [**JDK 8u162**](http://www.oracle.com/technetwork/java/javase/8u162-relnotes-4021436.html).
* Upgrade *Selenium* to current levels [**Version 3.10.0**](https://docs.seleniumhq.org/download/).
* Upgrade *ChromeDriver* [**ChromeDriver v2.37**](https://sites.google.com/a/chromium.org/chromedriver/downloads) level.
* Keep *Chrome* version at ***Chrome v64-66*** levels. ([as per ChromeDriver v2.37 release notes](https://chromedriver.storage.googleapis.com/2.37/notes.txt))
* *Clean* your *Project Workspace* through your *IDE* and *Rebuild* your project with required dependencies only.
* Use [*CCleaner*](https://www.ccleaner.com/ccleaner) tool to wipe off all the OS chores before and after the execution of your *test Suite*.
* If your base *Chrome* version is too old, then uninstall it through [*Revo Uninstaller*](https://www.revouninstaller.com/revo_uninstaller_free_download.html) and install a recent GA and released version of Chrome.
* Execute your `@Test`.

Upvotes: 0 <issue_comment>username_4: I have tried some of the solutions posted here without success, and I really did not want to delve into `node_modules`, but that is what I have done since my project is time sensitive. At least until a permanent solution is found.
In my app-level `build.gradle`, I have updated all Google dependencies to version 11.8.0, e.g. `compile "com.google.android.gms:play-services-base:11.8.0"`. Then in `react-native-onesignal's build.gradle`:
I changed these lines:
```
compile 'com.google.android.gms:play-services-gcm:+'
compile 'com.google.android.gms:play-services-analytics:+'
compile 'com.google.android.gms:play-services-location:+'
```
to the same specific version as follows:
```
compile 'com.google.android.gms:play-services-gcm:11.8.0'
compile 'com.google.android.gms:play-services-analytics:11.8.0'
compile 'com.google.android.gms:play-services-location:11.8.0'
```
That seems to fix the error. If anyone has a better solution, I'll gladly implement that in the project. In the meantime, I hope this helps someone else as well.

My approach was to build a wrapper class for the multiple generators from `keras.utils.Sequence` and then implement the base methods of it: `__len__` and `__getitem__`:
```
from keras.preprocessing.image import ImageDataGenerator
from keras.utils import Sequence
class MultipleInputGenerator(Sequence):
"""Wrapper of 2 ImageDataGenerator"""
def __init__(self, X1, X2, Y, batch_size):
# Keras generator
self.generator = ImageDataGenerator(rotation_range=15,
width_shift_range=0.2,
height_shift_range=0.2,
shear_range=0.2,
zoom_range=0.2,
horizontal_flip=True,
fill_mode='nearest')
# Real time multiple input data augmentation
self.genX1 = self.generator.flow(X1, Y, batch_size=batch_size)
self.genX2 = self.generator.flow(X2, Y, batch_size=batch_size)
def __len__(self):
"""It is mandatory to implement it on Keras Sequence"""
return self.genX1.__len__()
def __getitem__(self, index):
"""Getting items from the 2 generators and packing them"""
X1_batch, Y_batch = self.genX1.__getitem__(index)
X2_batch, Y_batch = self.genX2.__getitem__(index)
X_batch = [X1_batch, X2_batch]
return X_batch, Y_batch
```
You can use this generator with `model.fit_generator()` once the generator has been instanced.

```
logger.error("Entered value [" + val + "] is wrong")
```
But I don't want string concatenation because if you read the strings from right to left, they are in the wrong order. Is there any other way to do this?
I need to put `val` in the error message.<issue_comment>username_1: You can use `String.format` function.
`String output = String.format("Entered value [%s] is wrong", val);
logger.error(output);`
Have a look at more examples in the following post <https://dzone.com/articles/java-string-format-examples>
Upvotes: 0 <issue_comment>username_2: You can use [`String.format`](https://docs.oracle.com/javase/8/docs/api/java/lang/String.html#format-java.lang.String-java.lang.Object...-), like this
```
logger.error(String.format("Entered value[%s] is wrong", val));
```
This is supposing that `val` is a string. If it is not, you should change `%s` to something else (e.g., if `val` is an integer, you should use `%d`).
For further detail about format strings (like `%s`) check [here](https://docs.oracle.com/javase/8/docs/api/java/util/Formatter.html#syntax).

All hadlers are being processed. What I am missing is why the TAcroPDF seems to hog the focus.
I can manually double click into the TEdit but I need a less user-intensive solutrion<issue_comment>username_1: Using the LoadFile method caused focus issues
```
AcroPDF1.LoadFile(PDFFileName); //was the source of the focusing problem
```
use
```
AcroPDF1.src:=PDFFileName;
```
instead.
Upvotes: 0 <issue_comment>username_2: Sorry for the delayed response. One thing that I found that works is to use a TTimer; enable the Timer after you call LoadFile, and in the Timer event set the focus to your edtAmount. A timer delay of 500 milliseconds seems to work in my case. Disable the timer after the SetFocus call.

2018/03/21 | 617 | 2,242 | <issue_start>username_0: I'm working with a basic `std::ofstream` object, created as follows:
```
output_stream = std::ofstream(output_file.c_str());
```
This creates a file, where some information is put in. Let me show an example of such a message: (Watch window excerpt)
```
full_Message "Error while processing message:\r\n\tForecast Request:"
```
All this is ok, but after having launched following commands, there is a problem:
```
output_stream << full_Message;
output_stream.flush();
```
In order to see what is wrong, let's look at the hexadecimal dump of the file: (this is a hexadecimal display of the file, as seen in Notepad++. For clarity reasons I've taken a screenshot.)
[](https://i.stack.imgur.com/QqJUN.png)
As you can see, the character `0d` is doubled, resulting in following display:
```
Error while processing message:
Forecast Request:
```
(There's a newline too much, both lines should be directly one after the other)
I am aware of the addition of `#13` characters while doing file conversion from UNIX/Linux to Windows, but this is not relevant here: I'm purely working with a Windows file, on a Windows system, so there should be no need to add any `#13` character.
Does anybody have an idea how I can avoid this extra character being added?
Thanks in advance<issue_comment>username_1: Because by default the library converts `'\n'` to `"\r\n"` for text streams on platforms where it's needed (like Windows).
So you don't need your explicit carriage-return in your string. It's handled automatically.
If you want to specify the carriage-return explicitly, then you need to open the file in binary mode.
---
When reading a text stream, the opposite conversion happens, with `"\r\n"` being converted to `'\n'`.
Upvotes: 2 <issue_comment>username_2: The streams default to *text mode*, which means that in Windows, if you write `\n` then the file gets `\r\n`. Therefore , if you write `\r\n` then the file gets `\r\r\n`.
To fix this, either just write `\n` in your code; or open the file in *binary mode*:
```
auto output_stream = std::ofstream(output_file.c_str(), std::ios::binary);
```

Here it ask me to sign up to Microsoft Azure so I did sign in:
as I put my email where I subscribed to Microsoft Azure, it showed me that The server specified doesn't exist in any subscription:
I need help on how to enable the firewall, and have access to the server from my account, so I can keep working on the data.<issue_comment>username_1: You are seeing that message because your client/local IP address has not yet been added to the firewall rules on the SQL server.
To regain access to your SQL server from your local machine:
* use your web browser and login to the [Azure portal](https://portal.azure.com)
* locate your SQL server: **All services** -> **Databases** -> **SQL Servers**
* click on the name of your SQL server to open its properties page
* click on **Firewalls and virtual networks** (located under **Settings**)
* your current IP address should already be detected and viewable on the page, so go ahead and click the **+ Add client IP** button
* you can give the firewall rule a friendly name (it will default to "ClientIP\_X\_X\_X\_X")
* click the **Save** button and you're done.
Your client IP address is likely to change every few days by your Internet provider unless you are on a plan that gives you a static IP address.
Upvotes: 3 <issue_comment>username_2: You are having this problem because your Client Machine's IP does not have access to the Azure database. Like you have mentioned that you did have access till yesterday but today you cannot access it. It is probably your client machine has its IP set to dynamic and it changed its IP today.
To fix you will need to logon to your Azure Portal.
1. Go to the Azure SQL Database on your Azure Portal.
2. In the Details (3rd blade) click on `Set Server Firewall`
[](https://i.stack.imgur.com/Zg5qq.jpg)
3. At this point a new window will open and on the very first blade for `Firewall settings` click on `Add client IP`.
[](https://i.stack.imgur.com/M9bIH.jpg)
4. Click on the `Save` button and close it.
5. At this point your Client PC's IP would have been added to the Azure Firewall as a rule and you should be able to connect to Azure SQL Database from your Client Machine.

2018/03/21 | 706 | 2,667 | <issue_start>username_0: I have some old service accounts on a Google Cloud project. I want to find out if they are still being used or that I can safely delete them. Is there a way to see when they were last used? And maybe how often?
I guess I could just delete the key and hope nothing breaks, but that seems a bit iffy. Is there a better solution?<issue_comment>username_1: At this time, there is no tool within the Google cloud platform to list where exactly Service account keys are used, or when last they were used or how often they are used. However, with the [GCloud command line](https://cloud.google.com/sdk/gcloud/reference/iam/service-accounts/keys/list), you can list all Service Account keys (within your project) with the Creation Date(which is often the date of creation of the Service Account - For Default Keys) and the Expiry Date for the Key.
$ gcloud iam service-accounts keys list --iam-account [IAM\_account] --project [projectName]
You can verify if Keys of your old [User-managed Service account](https://cloud.google.com/iam/docs/service-accounts#user-managed_service_accounts) are not expired yet - Hence, they are probably still being used.
If you delete the service accounts that are still used by running instances, the instances may start failing their operations. However, you can contact the [Google Cloud platform team](https://cloud.google.com/support/docs/) to help with re-adding the deleted Service account back to your project.

```
data: str type string value 'abcd#',
len type i.
len = strlen( str ).
len = len - 1.
str = str+0(len).
```
Is there any elegant one-liner to do this? The only prominent way I found so far is
```
SHIFT str RIGHT DELETING TRAILING `,`.
```
However, it requires that you know what the last char is (TRAILING mask) and mask doesn't support regexp or wildcards. Or I am wrong?
This variant doesn't work for me for some reason
```
SHIFT string RIGHT BY 1.
```
Maybe somebody knows more beautiful syntax to do this in one line? Anything new in ABAP 7.40 or 7.50?<issue_comment>username_1: SUBSTRING to get the last character of a string:
```
DATA: str TYPE string VALUE 'abcd#'.
str = substring( val = str off = strlen( str ) - 1 len = 1 ).
```
str will be '#'
To remove the last character of a string (like in your example):
```
str = substring( val = str off = 0 len = strlen( str ) - 1 ).
```
Type in SUBSTRING in your ABAP Editor and hit F1 on it, there are some more variations (substring\_after, substring\_before, etc.)

2018/03/21 | 441 | 1,897 | <issue_start>username_0: I am trying to make ‘Would You Rather’ app.
This basically involves two options that the user picks (e.g. Chocolate or Vanilla).
I want to be able to store the amount of times people chose each option.
I can only really think of one way of doing this:
Having each option as it’s own row in a database, and incrementing this each time the user picks it.
However, surely this would require making a request every time the user answers a question, and therefore handling (depending on the number of users) thousands of requests a minute? And wouldn’t there be an issue with two people trying to update the value at once?
I’m not sure how the best way to go about doing this is.<issue_comment>username_1: I am not aware of programming language you are using so I will give a generalized answer.
If you want to save roundtrip from database one solution would be to create a temp file with votes for your options. This file can be update when user selects an option. To put these values in database you can create an background job which will collect data and store it in database in scheduled manner this will have a downside of not having current data in database but I think this will outweigh the benefits.
Upvotes: 2 <issue_comment>username_2: I would suggest having a table which holds individual votes. It can have three columns, ID, IP address/username (or another identifying bit of information to stop duplicate votes) and what they voted for.
Whenever you want to calculate the current votes you can just do the count query while filtering out duplicate IP addresses/usernames.
If you are worried about database scalabilty it may be worthwhile looking into buffering the inserts into the database. For example storing the votes every 20 seconds or so and doing a batch insert.

try {
console.log('Fix Start')
var rootDir = process.cwd()
// @nhancv: Preparing path

var nextIndex = keyIndex + keySearch.length
var path = androidSettingGradleFileData.substring(nextIndex, androidSettingGradleFileData.indexOf("')", nextIndex))
pathArr.push(path)
keyIndex++
}
var newVersion = '11.8.0'
var key = 'com.google.android.gms'
// @nhancv: Update version
for (var i = 0; i < pathArr.length; i++) {
var file = `${rootDir}/${pathArr[i]}/build.gradle`
var data = fs.readFileSync(file, 'utf8')
var result = data
var index = 0
var logs = []

var moduleNew = data.substring(index, versionIndexOf) + newVersion
if (moduleOrigin !== moduleNew) {
logs.push(`Replace: ${moduleOrigin} -> ${moduleNew}`)
result = result.replace(moduleOrigin, moduleNew)
fs.writeFileSync(file, result, 'utf8')

if (logs.length > 0) {
console.log(`Fix path: ${pathArr[i]}`)

console.log(`=> ${logs[j]}`)
}
}
}
console.log('Fix Done')
} catch (error) {
console.error(error)
}
```
Step 2: Update npm script in **package.json** file
```
"scripts": {
"postinstall": "node ./android-gradle-fix.js"
},
```
When ever you run npm install it will scan all android module and update with specific version 11.8.0 (you can change it in android-gradle-fix.js file)
---
When run npm install it will skip post install and you may facing with error:
postinstall: **cannot run in wd %s %s (wd=%s) node**
==> Fix add — unsafe-perm to npm install like
```
npm install --unsafe-perm
```

2018/03/21 | 623 | 2,174 | <issue_start>username_0: I am using nodejs mongo driver in my application. I set up below options in the connection:
```
{
connectTimeoutMS: 30000,
socketTimeoutMS: 30000,
// retry to connect for 120 times
reconnectTries: 120,
// wait 1 second before retrying
reconnectInterval: 1000
};
```
It will try to re-connect 120 times if the connection is broken and 1 second for each delay. I need to listen on the server status changes during re-connect. I added below event listeners:
```
db.on('close', this.onClose.bind(this));
db.on('error', this.onError.bind(this));
db.on('timeout', this.onTimeout.bind(this));
db.on('parseError', this.onParseError.bind(this));
db.on('reconnect', this.onReconnect.bind(this));
```
All the event listeners are working fine but my problem is how to detect that the reconnect failed after 120 times retries. For example, if the server is down then I will receive a close event. If the server is up during 120 seconds, I will receive reconnect event. But what if the server is not up in 120 seconds. How can I detect this change? Should I implement it by myself?<issue_comment>username_1: You can do it like this:
```
// Do this on your global scope //
var connectionAttemps = 0;
var doThisInsideYourTriggeredErrorEvent = function () {
connectionAttemps++;
if (connectionAttemps >= 120)
{
// Here goes your logic to stop the reconnection attempts //
}
/* Here goes your implemented logic (if any) for the "onError" event */
}
```
Check if it helps.

db.on('reconnectFailed', (err) => {

I've verified this works also for the 2.2 version of the nodejs mongodb driver, just not documented there at all.

```
This is the data without outliers (I deleted 11 outliers, but I have more)
[](https://i.stack.imgur.com/NDWa3.jpg)<issue_comment>username_1: **Answer**:
I assume that your problem is the following: First, you detect outliers (just like the boxplot function) and remove them. Afterwards, you produce boxplots with the cleaned data, which again shows outliers. And you expect to see no outliers.
This is not necessarily an error of your code, this is an error in your expectations. When you remove the outliers, the statistics of your data set change. For example, the quartiles are not the same anymore. Hence, you might identify "new" outliers. See the following example:
```
## create example data
set.seed(12345)
rand <- rexp(100,23)
## plot. gives outliers.
boxplot(rand)
## detect outliers with these functions
detectaOutliers = function(x) {
q = quantile(x, probs = c(0.25, 0.75))
R = IQR(x)
OM1 = q[1] - (R * 1.5) # outliers moderados
OM3 = q[2] + (R * 1.5)
OE1 = q[1] - (R * 3) # outliers extremos
OE3 = q[2] + (R * 3)
moderados = ifelse(x < OM1 | x > OM3, 1, 0)
extremos = ifelse(x < OE1 | x > OE3, 1, 0)
cbind(extOut = moderados)
}
detectOut <- function(x) boxplot(x, plot = FALSE)$out
## clean your data
clean1 <- rand[!as.logical(detectaOutliers(rand))]
clean2 <- rand[!rand%in%detectOut(rand)]
## check that these functions do the same.
all(clean1 == clean2 )
# Fun fact: depending on your data, clean1 and clean2
# are not always the same. See the extra note below.
## plot cleaned data
boxplot(clean2)
## Still has outliers. But "new" ones. confirm with:
sort(boxplot(rand)$out) # original outlier
sort(boxplot(clean2)$out) # new outlier
```
**Note 1:**
Your code does not necessarily use the same outlier identification as the boxplot function in R (I am not sure about the ggplot boxplot, but this is at least true for the graphics::boxplot function.):
```
## The boxplot function (rather: boxplot.stats)
## does not use the quantile function, but the fivenum function
## to identify outliers. They produce different results, e.g., here:
fivenum(rand)[c(2,4)]
quantile(rand,probs=c(0.25,0.75))
```
**Note 2**:
If you want boxplots that exclude outliers, you can use the `outline` parameter of the boxplot function (for ggplot, see [Ignore outliers in ggplot2 boxplot](https://stackoverflow.com/questions/5677885/ignore-outliers-in-ggplot2-boxplot))
Upvotes: 2 <issue_comment>username_2: 6 hours later, I realized that the error was in the variables I was using (my database has 4 variables and I needed to remove the outliers of a column alone, depending on two others and it turns out that I was wrong with the 2 I chose) Finally, I realized and the function works perfectly!

N1 = 8237

Also, I used [this answer](https://stackoverflow.com/questions/37024107/excel-vba-remove-unicode-characters-in-a-string) for this code.
This function will clean every single char of your data, so it should work for you. You need 2 functions: 1 to clean the Unicode chars, and other one to clean your item codes\_
```
Public Function CLEAN_ITEM_CODE(ByRef ThisCell As Range) As String
If ThisCell.Count > 1 Or ThisCell.Count < 1 Then
CLEAN_ITEM_CODE = "Only single cells allowed"
Exit Function
End If
Dim ZZ As Byte
For ZZ = 1 To Len(ThisCell.Value) Step 1
CLEAN_ITEM_CODE = CLEAN_ITEM_CODE & GetStrippedText(Mid(ThisCell.Value, ZZ, 1))
Next ZZ
End Function
Private Function GetStrippedText(txt As String) As String
If txt = "–" Then
GetStrippedText = "–"
Else
Dim regEx As Object
Set regEx = CreateObject("vbscript.regexp")
regEx.Pattern = "[^\u0000-\u007F]"
GetStrippedText = regEx.Replace(txt, "")
End If
End Function
```
And this is what i get using it as formula in Excel. Note the difference in the Len of strings:

Any information much appreciated.<issue_comment>username_1: From looking at a bot I have, I see this, too. If it's ok, I have a guess as to what it is.
I believe the bot itself is global in its location since it's just the code and settings for the bot. The App Service resource, however, is where the bot is deployed to on the web which does have a location.
Hopefully, you'll see the App Service in the North Europe location. :)

```
datasink4 = glueContext.write_dynamic_frame.from_options(
frame=dropnullfields3,
connection_type="s3",
connection_options={"path": "s3://my-s3-bucket/datafile.parquet"},

)
```
Is it possible to specify a KMS key so that the data is encrypted in the bucket?<issue_comment>username_1: glue scala job
```
val spark: SparkContext = new SparkContext()
val glueContext: GlueContext = new GlueContext(spark)
spark.hadoopConfiguration.set("fs.s3.enableServerSideEncryption", "true")
spark.hadoopConfiguration.set("fs.s3.serverSideEncryption.kms.keyId", args("ENCRYPTION_KEY"))
```
I think syntax should be differ for Python, but idea the same
Upvotes: 4 [selected_answer]<issue_comment>username_2: To spell out the answer using PySpark, you can do either
```
from pyspark.conf import SparkConf
[...]
spark_conf = SparkConf().setAll([
("spark.hadoop.fs.s3.enableServerSideEncryption", "true"),
("spark.hadoop.fs.s3.serverSideEncryption.kms.keyId", "")
])
sc = SparkContext(conf=spark\_conf)
```
noticing the `spark.hadoop` prefix - or (uglier but shorter)
```
sc._jsc.hadoopConfiguration().set("fs.s3.enableServerSideEncryption", "true")
sc._jsc.hadoopConfiguration().set("fs.s3.serverSideEncryption.kms.keyId", "")
```
where `sc` is your current SparkContext.
Upvotes: 2 <issue_comment>username_3: This isn't necessary. Perhaps it was when the question was first posed, but the same can be achieved by creating a security configuration and associating that with the glue job. Just remember to have this in your script, otherwise it won't do it:
```
job = Job(glueContext)
job.init(args['JOB_NAME'], args)
```

2018/03/21 | 871 | 3,112 | <issue_start>username_0: I'm trying to delete lines in specific column from all rows that contains specific words.
For example:
Remove lines that contain word `apple` and it is always at the beginning of the line.
```
+--+------------------+
|ID|data |
+--+------------------+
|1 |sometext1 |
| |sometext2 |
| |apple sometext3 |
| |sometext4 |
+--+------------------+
|2 |apple sometext5 |
| |sometext6 |
+--+------------------+
```
so the result would be:
```
+--+------------------+
|ID|data |
+--+------------------+
|1 |sometext1 |
| |sometext2 |
| |sometext4 |
+--+------------------+
|2 |sometext6 |
+--+------------------+
```
'SometextX' is different in every line, number of lines is different in every row and it has different number of characters in every line.
I really need this in MySQL any help would be appreciated.<issue_comment>username_1: You would use `where`:
```
where textcol not like 'apple%' or textcol is null
```
This can be part of a `select` or a `delete` (the question mentions "result" which suggests the former and "delete" which suggests the latter). It is not clear whether you actually want to change the data or whether you just want the result set without these words.
Note: you can do this without `or` and still handle `NULL` values, because MySQL has a `NULL`-safe equality operator:
```
where not left(textcol, 5) <=> 'apple'
```
Upvotes: 0 <issue_comment>username_2: You would be better off using `REGEXP` here to match patterns in each line:
```
DELETE FROM yourTable WHERE text REGEXP '^apple';
```
`REGEXP` allows for fairly complex regex matching, and would be useful if your requirement changes or gets more complex later on.
**Edit:** MySQL has no built in support for regex replacement, so there is no easy way to accomplish what you want.
A general regex pattern to remove the word `apple` would be `\bapple\b`. You may search on this pattern and replace with empty string.

update your_table set text=if((@start:=locate('apple',text))=1,replace(text,substring(text,@start,locate('\n',text,@start+1)-@start+1),''),text);
update your_table set text=if((@start:=locate('apple',text))=1,replace(text,substring(text,locate('apple',text)),''),text);

update #1 will remove apple *in the middle* of the text (prefixed by `\n`)
update #2 will remove apple *at the beginning* of its row (nothing before) and having following rows
update #3 will remove remaining cases

If possible to do all of the logic in the **configure method** then it would be great.
**application.properties:**
BASIC AUTHENTICATION
====================
```
user.name=test
user.password={<PASSWORD>
```
**SecurityConfig class:**
```
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
private static final Logger logger = LoggerFactory.getLogger(SecurityConfig.class);
private AuthenticationProvider authenticationProvider;
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable().authorizeRequests().anyRequest().authenticated().and().httpBasic()
.and().sessionManagement().and().authenticationProvider(authenticationProvider)
.sessionCreationPolicy(SessionCreationPolicy.STATELESS)
}
```
***UPDATED CODE***
```
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

return new BCryptPasswordEncoder();
}
@Bean
public String generateHashedPassword(String password) {
return BCrypt.hashpw(password, BCrypt.gensalt(10));
}
}
```
**UPDATE 2**
Currently the way it works now is when i start the application, i visit localhost:8080 then a login popup appears and i type the username and password (that are defined in application.properties)
if I type the right username and password i get logged in but if i manage to login with the username and password defined in application.properties then whats the point with hashing the password? I was thinking more like having a list of hashed keys and compare the input password with the list and if success then login.<issue_comment>username_1: I think you need to implement your own AuthenticationProvider like in [this](https://stackoverflow.com/questions/31826233/custom-authentication-manager-with-spring-security-and-java-configuration) question. In the `authenticate()` method you can do the hashing of the retrieved password and check if it matches the one from your application.properties.
Upvotes: 0 <issue_comment>username_2: Since you want to define your credentials in properties file, I guess you can take advantage of inmemory authentication. Try the following:
```
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
private static final Logger logger = LoggerFactory.getLogger(SecurityConfig.class);
private AuthenticationProvider authenticationProvider;
@Value("${user.name}")
private String userName;
@Value("${user.password}")
private String userHashedPassword; // <PASSWORD>
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable().authorizeRequests().anyRequest().authenticated().and().httpBasic()
.and().sessionManagement().and().authenticationProvider(authenticationProvider)
.sessionCreationPolicy(SessionCreationPolicy.STATELESS)
}
@Override
public void configure(AuthenticationManagerBuilder auth) throws Exception
{
auth
.inMemoryAuthentication()
.passwordEncoder(passwordEncoder())
.withUser(userName)
.password(<PASSWORD>);
}
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
}
```
Please, note, that in this case your password should be encrypted with `BCryptPasswordEncoder` first, and then you should put it into properties file (you can use its `encoder.encode("password")` method). Or you can use any other implementation of `PasswordEncoder` if you want. I've also noticed that you're using some custom autenticationProvider. Not sure how it works since you didnt share the code, and not sure that it will get along with inmemory autentication. But, anyway, I think it worth a shot and this is the right way to go in your scenario.
Hope it helps.

Upvotes: 2 <issue_comment>username_6: I've got the same problem and finally sorted out. It's usually caused by your upgrade of Android Studio from 2.x to 3.x at the same time.
In short, it's because Flutter is not correctly configurated, but behind the scene there might be different reasons, so the universal solution is to run **`flutter doctor -v`** to diagnose and see what's missing.
[First make sure you've already followed the setup steps in Flutter's official documentation and have your Android SDK updated.]
In my own case, a couple of things to fix:
1. Update the JAVA\_HOME path in `.bash_profile`. Because I have 2 Java versions installed and so I updated it to use the same as Android Studio does. This is critical as `flutter doctor` relies on Java to check some of your configurations.
2. `Some Android licenses not accepted` - follow flutter doctor's advice to accept all licenses.
3. Android Studio's Flutter plugin version too low - simply update it.

Anyway, the following procedure helped me:
1. uninstall the Flutter plugin
2. restart Android Studio.
3. uninstall the Dart plugin
4. restart Android Studio again which seemed important to do
5. install the Dart plugin again
6. restart Android Studio although it is annoying
7. install the Flutter plugin again
8. and guess: restart Android Studio

I simply install **flutter** and **dart** plugins and restarted Android Studio.
After restarting I noticed that there is no Wizard for creating flutter apps. But soon I realized that I have disabled some plugins ( Android Studio's default plugins ) so I enabled all plugins and restarted Android Studio again and BOOM! Now there is a wizard for Creating Flutter Apps.
Hope this helps you !

First and foremost **Flutter** and **Dart plugins** must be installed before.

After installing these plugins you can check if it is ok or not with `flutter doctor`

If you hadn't installed the plugins you would have this:

2. Restart Android Studio
3. Install Flutter Plugin (it will prompt you to install Dart plugin as well. Accept it)
4. Restart Android Studio
Also, reminder to check whether the plugin is enabled or not. Go to Preferences -> Plugins -> Flutter/Dart. Although, it's enabled by default, you may have had to disable it at some point in the past. In that case, just enable it from Preferences -> Plugin -> Flutter/Dart if you want to.

2018/03/21 | 433 | 1,834 | <issue_start>username_0: I used StanfordCoreNLP jar file library to split English paragraphs into sentences but I could retrieve the split sentences as CoreMap Object, but I want to convert those split sentences of type CoreMap to type String, is there anyway to achieve this task. The bold text in the code shows the area where CoreMap is used and I want the sentences retrieved to convert it to String
The code snippet:
```
props.setProperty("annotators","tokenize,ssplit");
//put that in a pipeline
StanfordCoreNLP pipeline = new StanfordCoreNLP(props);
//a data structure for the annotation
Annotation document = new Annotation(text);
// run the pipeline on that data structure
pipeline.annotate(document);
// access the annotations which has worked on a sentence
List sentences = document.get(SentencesAnnotation.class);
PrintStream printStream = new PrintStream(new FileOutputStream("/home/sakshi/Desktop/Admin\_System/translate.en"));
PrintStream console = System.out; // To store the reference to default output stream to use it to restore the default std output stream
System.setOut(printStream);// To change the default output stream
\*\*for (CoreMap sentence : sentences) {
System.out.println(sentence);\*\*
}
System.setOut(console);
response.setContentType("text/plain");
response.getWriter().write(text);
```<issue_comment>username_1: Not sure about exact types of the CoreMap, but probably Map#values() is a List that you need. To convert it into the single String you could use Java8 Streams API:
```
list.stream ().map (i -> i.toString ()).collect (Collectors.joining (","));
```

I have a .env file which has my sql database settings inside, but I also have a file in config/database.php that has these settings inside.
When I deploy my application to an Elastic Beanstalk instance, which of these files is it using for the database settings?<issue_comment>username_1: In your ".env" file you have your settings. in the ".php" files like your "database.php" file this is the default value for the property and normally, the corresponding value in the ".env" file is use here with this syntax : `'database' => env('database', 'default_value'),`
Upvotes: 2 <issue_comment>username_2: The .env file is the first file it will use for configs. In case values are missing inside the .env file Laravel will check the config files. I primairly use those as backups.
Upvotes: 1 <issue_comment>username_3: .env is short for environment and thus that is your environment configurations.
The `database.php` configuration contains non-critical information.
You obviously won't have your database's username's password in your source control or available in the code.
In order to keep everything safe or to keep information saved that is environment-defined... you keep them in `.env` file
Laravel will prioritize `.env` variables.
Upvotes: 4 [selected_answer]<issue_comment>username_4: A little more detailed answer:
The config Files are where you store all configurations. You shouldn't add any username, passwords or other secret informations in them, because they will be in your source control.
All secret informations and all environment dependant informations should be stored in your .env file. With this you can have different configuration values in local/testing/production with just a different .env file.
In your config files you access the information in you .env files, if necessary.
When use what from [another answer](https://stackoverflow.com/questions/40026893/what-is-difference-between-use-envapp-env-configapp-env-or-appenviron/42393294?noredirect=1#comment101701849_42393294)
* use env() only in config files
* use App::environment() for checking the environment (APP\_ENV in .env).
* use config('app.var') for all other env variables, ex. config('app.debug')
* create own config files for your own ENV variables. Example:
In your .env:
MY\_VALUE=foo
example config app/myconfig.php
```
return [
'myvalue' => env('MY_VALUE', 'bar'), // 'bar' is default if MY_VALUE is missing in .env
];
```
Access in your code:
```
config('myconfig.myvalue') // will result in 'foo'
```

These three topic needs to be joined in one Topic Message where i can get the Result Model that is a combination of the 3 Topic Messages.
There are many example that shows how to join 2 topics.
If anyone can give me an example or a hint of how can i make a Join or these 3 Topics.<issue_comment>username_1: Until the [cogroup feature](https://cwiki.apache.org/confluence/display/KAFKA/KIP-150+-+Kafka-Streams+Cogroup "coo") gets implemented, you will need to first merge your first 2 topics into an intermediary topic, and then join that one with your 3rd topic.
For an example of how to do that, see [the cogroup KIP](https://cwiki.apache.org/confluence/display/KAFKA/KIP-150+-+Kafka-Streams+Cogroup "coo").
Upvotes: 2 <issue_comment>username_2: I depends on what kind of join you want to do. As you say, you have `KStream`, you would do two consecutive windowed joins:
```java
KStream stream1 = builder.stream(...);
KStream stream2 = builder.stream(...);
KStream stream3 = builder.stream(...);
KStream joined = stream1.join(stream2, ...)
.join(stream3, ...);

```
Collections.max(list);

To get the max or min of an arraylist, but I am looking for a way to get the max or min between a certain range.
For example, what is the max between index 0 and index 5?<issue_comment>username_1: Use `list.subList` to run the operation on a portion of the `List`:
```
Collections.max(list.subList(0,6));
```
`list.subList(0,6)` returns a view of the portion of the original list between indices 0 and 5 (inclusive).
Upvotes: 4 [selected_answer]<issue_comment>username_2: You can go with sublist. Make a list with range and then pass it as param to the max.
For ex :
```
Collections.max(list.subList(0,6));

2018/03/21 | 1,461 | 4,088 | <issue_start>username_0: I have the following pandas dataframe:
```
count event date
0 1544 'strike' 2016-11-01
1 226 'defense' 2016-11-01
2 1524 'strike' 2016-12-01
3 246 'defense' 2016-12-01
4 1592 'strike' 2017-01-01
5 245 'defense' 2017-01-01
```
I want to pivot/transform it in such a way the final output looks like this:
```
event 2016-11-01 2016-12-01 2017-01-01 2017-02-01 2017-03-01
'strike' 1544 1524 1592 1608 1654
'defense' 226 246 245 210 254
```
but what i'm getting now upon pivoting is this:
```
count count count count count\
date 2016-11-01 2016-12-01 2017-01-01 2017-02-01 2017-03-01
event
'strike' 1544 1524 1592 1608 1654
'defense' 226 246 245 210 254
```
is there any way i could remove the entire empty row ahead of the `event` index-name and rename the `date` index-name with `event` as its index-name and also remove the unwanted `count` appearing in the first row of the data frame? The data seems to be transforming correctly i just want to get rid of these headers and indexes and have the renamed and removed properly. I also don't want the row labels in the desired output.
This is what i've been trying till now:
```
output = df.pivot(index='event', columns='date')
print(output)
```<issue_comment>username_1: Solution is add parameter `values` to [`pivot`](http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.pivot.html), then add [`reset_index`](http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.reset_index.html) for column from `index` and [`rename_axis`](http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.rename_axis.html) fro remove column name:
```
output=df.pivot(index='event',columns='date',values='count').reset_index().rename_axis(None,1)
print(output)
event 2016-11-01 2016-12-01 2017-01-01
0 'defense' 226 246 245
1 'strike' 1544 1524 1592
```
What happens if omit it?
```
print (df)
count event date count1
0 1544 'strike' 2016-11-01 1
1 226 'defense' 2016-11-01 7
2 1524 'strike' 2016-12-01 8
3 246 'defense' 2016-12-01 3
4 1592 'strike' 2017-01-01 0
5 245 'defense' 2017-01-01 1
```
`pivot` use each not used column and create `MultiIndex` for distinguish original columns:
```
output = df.pivot(index='event', columns='date')
print(output)
count count1
date 2016-11-01 2016-12-01 2017-01-01 2016-11-01 2016-12-01 2017-01-01
event
'defense' 226 246 245 7 3 1
'strike' 1544 1524 1592 1 8 0
```
Upvotes: 4 [selected_answer]<issue_comment>username_2: I would recommend using the more general version of `pd.pivot()`, which is `pd.pivot_table()`, like so:
```
x = pd.pivot_table(df, index = 'event', columns = 'date', values = 'count')
```
You will get:
```
date 01/01/2017 01/11/2016 01/12/2016
event
'defense' 245 226 246
'strike' 1592 1544 1524
```
Next, you can get rid of the 'date' string by setting:
```
x.columns.name = ' '
```
Additionally, if you want to change the order of the events, you might want to set the variable up as a categorical variable, before doing the pivoting:
```
df.event = df.event.astype('category') # cast to categorical
df.event.cat.set_categories(your_list, inplace = True) # force order
```
where `your_list` is the list of your categories, in order.
Hope this helps.

2018/03/21 | 792 | 3,122 | <issue_start>username_0: I have a failing Jest test case for code where I'm using promises. It looks like the resolution of the promise is happening after the test has completed, meaning I can't check that my promise resolution code has been executed.
It feels like I need to make the event loop tick so the promise is resolved and the resolution code is executed, but haven't found anything that can do that in Jest.
Here's a sample case. The code to be tested:
```
const Client = require('SomeClient');
module.exports.init = () => {
Client.load().then(() => {
console.log('load resolved');
setTimeout(() => {
console.log('load setTimeout fired, retrying init');
module.exports.init();
}, 1000);
});
};
```
Test code:
```
jest.useFakeTimers();
const mockLoad = jest.fn().mockImplementation(() => Promise.resolve());
jest.mock('SomeClient', () => {
return {
load: mockLoad
};
}, { virtual: true });
const promiseTest = require('./PromiseTest');
describe('SomeClient Promise Test', () => {
it('retries init after 10 secs', () => {
promiseTest.init();
expect(mockLoad).toHaveBeenCalledTimes(1);
expect(setTimeout).toHaveBeenCalledTimes(1); // <-- FAILS - setTimeout has not been called
jest.runAllTimers();
expect(mockLoad).toHaveBeenCalledTimes(2);
});
});
```
The `expect(setTimeout).toHaveBeenCalledTimes(1);` assertion fails (`setTimeout` has not been called at all), I think because the promise has not yet been resolved.
Am I doing something wrong here? Can I cause the event loop to tick inside the test?<issue_comment>username_1: To tick the event loop inside your test, you should make it asynchronous.
A nice workaround was suggested on [GitHub](https://github.com/facebook/jest/issues/2157#issuecomment-279171856).
Having `flushPromises` as suggested there
```
function flushPromises() {
return new Promise(resolve => setImmediate(resolve));
}
```
your test will look like
```
describe('SomeClient Promise Test', () => {
it('retries init after 10 secs', () => {
promiseTest.init();
expect(mockLoad).toHaveBeenCalledTimes(1);
// notice return so jest knows that the test is asynchronous
return flushPromises()
.then(() => {
expect(setTimeout).toHaveBeenCalledTimes(1);
jest.runAllTimers();
expect(mockLoad).toHaveBeenCalledTimes(2);
});
});
});
```
Or the same using `async/await`:
```
describe('SomeClient Promise Test', () => {
it('retries init after 10 secs', async () => {
promiseTest.init();
expect(mockLoad).toHaveBeenCalledTimes(1);
await flushPromises();
expect(setTimeout).toHaveBeenCalledTimes(1);
jest.runAllTimers();
expect(mockLoad).toHaveBeenCalledTimes(2);
});
});
```

We needed these two bits in our test:
```
export function flushPromises(): Promise {
return new Promise(jest.requireActual("timers").setImmediate);
}
```
```
await flushPromises();

2018/03/21 | 551 | 1,763 | <issue_start>username_0: I have a python program that has to be running all the time. If for some reason it was stopped I want to restart it automatically. I thought of having a cron that will run every n number of seconds and check the program is running. My shell script is looks like this:
```
#!/usr/bin/env bash
CM_COMMAND=`ps aux| grep abc| grep def| grep sudo`
LEN_COMMAND=${#CM_COMMAND}
if[["$LEN_COMMAND" -le "5"]]
then
echo "start the python program"
fi
exit
```
When I run this script I am getting the error: `my_prog.sh: line 4: $'if[[118\r -le 5]]\r': command not found'`
What is the alternative of doing this and what is the problem with my script?<issue_comment>username_1: Maybe this would be more robust?
1) save the PID of your process when you start it with:
```
{your_python_command} & echo $! >>/{some_folder}/your_app.pid
```
2) This script will check and restart if it can't find the PID..
```
#!/usr/bin/env bash
PID=`cat /{some_folder}/your_app.pid`
if ! ps -p $PID > /dev/null
then
rm /{some_folder}/your_app.pid
{your_python_command} & echo $! >>/{some_folder}/your_app.pid
fi
```
3) To add it to a cronjob:
```
crontab -e
```
choose your text editor and add this row at the end of the file:
```
*/1 * * * * /{your_path}/{your_script_name}
```
exit and save
(this will run the script every minute, check crontab manual to set your exact interval)

```
mapfile -t array < <( **C)**
```
This command reads file `B` into an array. From the array a `sed` command is constructed. The `sed` command will filter out all entries and delete blank lines.
In your example, the constructed command ...
```
sed -r 's/(A|D|J|M|U|V)\t?//g;/^$/d' A > C
```
... generates the following file `C` (spaces are actually tabs)
```
B C E

2018/03/21 | 893 | 2,966 | <issue_start>username_0: How can I loop through multiple arrays and "pair" them, when declaring an object? Assuming there are two arrays that contain same amount of data. I would like to map each of them and allocate to objects properties.
This is what I would like to achieve:
```
{
name: john,
surname: doe,
datasets: [{
data: 1,
vehicle: car,
color: red
},
{
data: 2,
vehicle: car,
color: blue,
},
{
data: 3,
vehicle: car,
color: green
}]
}
```
this is what I have done:
```
function Constructor (name, surname, data, vehicle, colors) {
this.name = name;
this.surname = surname;
this.data = data;
this.vehicle = vehicle;
this.colors = colors;
this.person = {
name: name,
surname: surname,
datasets: [{
data: data.map(data => ({
data,
vehicle: vehicle,
color: colors.map(color => ({
color
}))
})),
}]
}
};
var testing = new Constructor ('john', 'doe', [1,2,3], 'car', ['red', 'blue', 'green']);
console.log (testing.person);
```<issue_comment>username_1: If `data` and `color` always have identical lengths, you can use the `index` in your map function, which is passed as a second argument:
```
data.map((data, i) => ({
data,
vehicle: vehicle,
color: colors[i]
})
)
```
For non-matching data sets (i.e.: one has more data than the other), there are several approaches you could take.
1. Use a default color (if `data` has more items):
```
data.map((data, i) => ({
// ...
color: colors[i] || "black"
})
```
2. Throw an error if the data-sets do not align:
```
if (data.length !== colors.length) throw "data length does not match color length";
```
3. Take the shortest set of data and discard the extra's
```
Array.from(
{ length: Math.min(data.length, colors.length) },
(_, i) => ({
data: data[i], color: colors[i], vehicle
})
);
```
And, of course, many more!
Upvotes: 3 [selected_answer]<issue_comment>username_2: I'm just going to propose an alternative solution you may not have thought of. If `colors.length <= data.length` is always `true`, you can consider cycling through the colors using `%` remainder operator like so:
```
data.map((data, i) => ({
data,
vehicle: vehicle,
color: colors[i % colors.length]
})
```
```js
function Constructor(name, surname, data, vehicle, colors) {
this.name = name;
this.surname = surname;
this.data = data;
this.vehicle = vehicle;
this.colors = colors;
this.person = {
name: name,
surname: surname,
datasets: [{
data: data.map((data, i) => ({
data,
vehicle: vehicle,
color: colors[i % colors.length]
}))
}]
}
}
var testing = new Constructor('john', 'doe', [1, 2, 3, 4, 5], 'car', ['red', 'blue', 'green']);
console.log(testing.person);
```
Which produces the sequence `red, blue, green, red, blue` for `data.length === 5`

2018/03/21 | 962 | 3,226 | <issue_start>username_0: I am trying to create type information for my event listeners. As all event listeners are set on the same `.on()` function, I am using generics.
```
type Name = "error" | "connected";
type Callback = {
error: (err: Error) => void,
connected: (err: number) => void,
};
function on(eventName: T, callback: Callback[T]): void { }
on("error", (err) => err.stack);
on("connected", (err) => err.stack);
```
I would expect the above to give me an error for the `connected` event as I attempt to use a `number` as an `Error`, however I get no type hinting at all for my callback functions.
However if all function definitions in `Callback` match, it does begin to work. As below:
```
type Callback = {
error: (err: Error) => void,
connected: (err: Error) => void,
};
```

Event can be listed in some enum.
```
enum EVENTS{
ERROR = "ERROR",
CONNECTED = "CONNECTED"
}
```
on method can be not generic
```
function on(eventName: EVENTS, callback: (v: any) => void): void { }

And just few examples
```
on(EVENTS.ERROR, (v: any) => {
if(v instanceof Error){
console.log(v.stack);
}
});
on(EVENTS.CONNECTED, (v:any) => {
console.log(v);

As usual it is hard to set type of event value.
Sorry. Here is edited function.
```
function on(eventName: EVENTS, callback: (v: T) => void): void { }
on(EVENTS.ERROR, (err) => {

**Speculation on why**: If you type the second parameter, as `Callback[T]`, the engine will try to determine `T` based on the argument type. So if you don't explicitly specify the type for the arrow function, the inference engine will infer the parameter for the arrow function to be `any` and try to guess `T` based on the arrow function type. (If you run with strict you will actually receive an error that the parameter has type `any` implicitly).
There are two possible solutions:
Use a two function approach, where `T` is determined in the first call and is known for the second call where the parameter is passed:
```
type Callback = {
error: (e: Error) => void
connected: (e: string) => void
};
function on(eventName: T) {
return function(callback: Callback[T])
{
};
}
on("error")(e=> e.stack);
on("connected")(e=> e.substr(1));
```
If the only thing that differs between functions is the parameter type and you are using 2.8 or older (unreleased at the time of writing but it is in RC, you can get it via `npm install -g typescript@rc`) you can get just the argument that differs, and the inference engine will not try to use the second parameter to infer `T`
```
type Arg0 = T extends (p1: infer U) => any ? U: never;
function on(eventName: T, callback: (e: Arg0) => void) : void { }
on("error", e=> e.stack);
on("connected", e=> e.substr(1));

```
add(new: Add): Observable {
return this.http
.post(this.addURL, new , httpOptions)
.map((response: Response) => {
if (response) {
if (response.status === 200) {
return [{ status: response.status, response: response.json() }]
}
}
})
.catch(this.handleError);
}
```
Here is my component.ts code where I want to call the list after successful add
```
addDetails(): void {
var new = this.form.value.array;
new = JSON.stringify(this.form.value.array);
this.addService.add(new)
.subscribe(
resultArray => this.Response = resultArray,
error => console.log("Error :: " + error),
)
if(Response.status ===200){
this.getList();
}}
```
but I am getting the below error:
**Property 'status' does not exist on type 'typeof Response'**<issue_comment>username_1: Seems you doing over engineering things.
Event can be listed in some enum.
```
enum EVENTS{
ERROR = "ERROR",
CONNECTED = "CONNECTED"
}
```
on method can be not generic
```
function on(eventName: EVENTS, callback: (v: any) => void): void { }
```
And just few examples
```
on(EVENTS.ERROR, (v: any) => {
if(v instanceof Error){
console.log(v.stack);
}
});
on(EVENTS.CONNECTED, (v:any) => {
console.log(v);
});
```
As usual it is hard to set type of event value.
Sorry. Here is edited function.
```
function on(eventName: EVENTS, callback: (v: T) => void): void { }
on(EVENTS.ERROR, (err) => {
console.log(err.stack);
});
on(EVENTS.CONNECTED, (v) => {
console.log(v);
});

2018/03/21 | 867 | 2,990 | <issue_start>username_0: I am trying to delegate the html rendering of a tree to a web worker. The tree is composed of nodes, each nodes has references to the next, previous and parent nodes.
The data that represents the tree is an array, containing all the root nodes. This array is post to the web worker as is, since the serializer of the web worker is supposed to support circular references.
When there's few nodes, everything goes well.
Using Chrome browser, when the number of nodes reaches a limit, the web worker do not receive anything ; its message's data is simply null. No error appears in the console.
With Firefox, IE and Edge, everything is OK. But I need Chrome to work to.
I tried to simplify my code and make a case test (see the jsFiddle below), and it appears that the problem comes from the circular reference to the next node.
In this case test, with 100 elements everything goes well, with 1000 it doesn't work.
Is there any solution to this problem ?
Is the only solution to change my code to remove circular references ?
HTML:
```
Test 100Test 1000
```
Javascript:
```
var workerCode = "self.onmessage = function(e) { self.postMessage(e.data ? 'ok ' + e.data.length : 'ko : null data'); };",
blob = new Blob([workerCode], {type: 'text/javascript'}),
blobUrl = URL.createObjectURL(blob),
worker = new Worker(blobUrl);
var btn_100 = document.getElementById('btn_100'),
btn_1000 = document.getElementById('btn_1000');
worker.onmessage = function(e) {
var log = document.createElement('p');
log.innerHTML = 'Response:
```
' + e.data + '
```
';
document.body.appendChild(log);
};
btn_100.onclick = function() { send(worker, 100); };
btn_1000.onclick = function() { send(worker, 1000); };
function send(w, n) {
var a = [];
for (var i = 0; i < n; i++) {
a.push({});
if (i > 0) a[i - 1].next = a[i];
}
w.postMessage(a);
}
```
Link to jsFiddle : <https://jsfiddle.net/jvr4a50r/><issue_comment>username_1: Actuallty,shallow copy happen in next property of object with in array. So for removing circular references, you have to do deep copy in next property.
You can remove circular references by updateing the send function in following way.
```
var a = [];
for (var i = 0; i < n; i++) {
a.push({});
if (i > 0)
a[i - 1].next = JSON.parse(JSON.stringify(a[i]));
}
```

<https://bugs.chromium.org/p/chromium/issues/detail?id=825466>
So far, to ensure having no problems, the only solution is to remove circular references in objects.
In this case I followed these steps:
* give a unique id to each node
* flatten the tree by putting all nodes in a "hasmap", the key is the unique id
* in nodes, replace all references to other nodes by the unique id
* and of course change all the code that used references to access objects indirectly through the hashmap

2018/03/21 | 1,310 | 4,312 | <issue_start>username_0: I want to create android application "Points of interest". I've read many different tutorials, and I do not understand why I need to convert GPS coordinates to ECEF and then to ENU. Can you explain, please?
Thanks!<issue_comment>username_1: Geospatial coordinate systems are a big topic, but the main choice between systems such as ECEF and ENU is about whether you want to describe a large region of the Earth's surface or just a small region.
When Android provides a [geolocation](https://developer.android.com/reference/android/location/Location.html) via the [LocationListener](https://developer.android.com/reference/android/location/LocationListener.html) API, it typically does this using latitude/longitude/altitude which is ideal for representing any point over the Earth's surface, but is a "polar" or "geodetic" coordinate system that isn't ideal for plotting 2D locations. Standard [techniques](https://en.wikipedia.org/wiki/Geographic_coordinate_conversion#From_geodetic_to_ECEF_coordinates) allow this coordinate system to be converted into ECEF, which is another coordinate system which is suitable for the whole globe, but is "cartesian" so can be rotated and scaled using much simpler mathematical operations than the original latitude/longitude/altitude coordinates.
Earth-Centred Earth Fixed ([ECEF](https://en.wikipedia.org/wiki/ECEF)) uses a coordinate system with its origin at the Earth's centre, so that any point on the ground will have coordinate values that are typically in the millions of metres. This is great for describing satellite orbits, or locations that span multiple continents, but not very convenient for 2D plots of points of interest within a town or city.
If you want to draw a 2D map of a small region of the Earth's surface, then the East-North-Up coordinate system may be much more convenient. To use this, you need a reference location (such as the centre of a particular city) about which the local East/North/Up directions can be defined. Those then provide a set of x/y/z axes, where the x & y axes might be directly converted into the 2D screen coordinates. Obviously, as the region of interest grows larger (e.g. more than 100km), the effects of the Earth's curvature become more noticeable, and an ENU coordinate system will be less useful. See [wikipedia](https://en.wikipedia.org/wiki/Geodetic_datum) for more info.
Moving from an ECEF to ENU coordinate system can be done by a simple set of matrix additions & multiplications which can be computed from the ECEF location of the centre of the map, and the unit vectors in the east/north/up directions.

if (this.speed != 0) {

emitPlayerData () {

socket.emit('move-player', {
x: this.sprite.body.x,
y: this.sprite.body.y,
angle: this.sprite.body.rotation,
```<issue_comment>username_1: You can create temporary timestamp to check what was the last time you emitted the data and only emit if it was more than 250ms ago. For example:
```
var lastUpdated = Date.now(); //get current timestamp
if (this.speed != 0 && lastUpdated + 250 <= Date.now()) { // if last updated timestamp + 250ms is smaller than current timestamp
lastUpdated = Date.now(); //update the lastUpdated timestamp
this.emitPlayerData();
}

```
if (this.speed != 0) {
this.emitPlayerData()
}
```
would be
```
if (this.speed != 0) {
debounce(this.emitPlayerData, 250, true)
}
```
Notice the debounce API, which is `debounce(expensiveFunction, ms, immediate)`
Example of a debounce function
```
// Returns a function, that, as long as it continues to be invoked, will not
// be triggered. The function will be called after it stops being called for
// N milliseconds. If `immediate` is passed, trigger the function on the
// leading edge, instead of the trailing.
function debounce(func, wait, immediate) {
var timeout;
return function() {
var context = this, args = arguments;
var later = function() {
timeout = null;
if (!immediate) func.apply(context, args);
};
var callNow = immediate && !timeout;
clearTimeout(timeout);
timeout = setTimeout(later, wait);
if (callNow) func.apply(context, args);
};
};

2018/03/21 | 935 | 3,379 | <issue_start>username_0: I have a simple code in which I try to split numbers into digits:
```
for n in 10...12
{
let numberIntoString = String(n)
let splitNumber = Array(numberIntoString)
let charIntoString = splitNumber.map {String($0)}
let numberIntoInteger = charIntoString.map {Int($0)}
print(numberIntoInteger)
}
```
and the output is:
```
[Optional(1), Optional(0)]
[Optional(1), Optional(1)]
[Optional(1), Optional(2)]
```
I did some research about "Optional" and find out that this term has something to do with wrapping/unwrapping value but to understand this fully I need someone to explain me this on my own code. So, my questions are: Why optional value appeared in my code and how to get rid of this unexpected output?
Also, I would like to know is there any way to write this code "better" (i.e. more readable)?<issue_comment>username_1: You can create temporary timestamp to check what was the last time you emitted the data and only emit if it was more than 250ms ago. For example:

* Affiliations
* Users
* Certificates
Kindly help me how and where I can find fabric ca database,
Thank You.<issue_comment>username_1: If you are using version 1.1, you can use the **fabric-ca-client affiliation list** and **fabric-ca-client identity list** commands to see the affiliations and users table, respectively. The ability to list the certificates will be in a future version of the fabric-ca-client.
By default, the **fabric-ca-server** uses SQLITE and the name of the database file is **fabric-ca-server.db** in the home directory of the fabric-ca-server. You can use the **sqlite3 fabric-ca-server.db** command to enter a sqlite shell, and then issue **select \* from users** to list the users table for example.
Upvotes: 3 [selected_answer]<issue_comment>username_2: You need to login to the docker container to run sqlite3 fabric-ca-server.db. Follow these steps:
```
$ docker ps
```
find your Fabric-ca container name from the response. Then issue this command:
```
$ sudo docker exec -it /bin/bash
```
After logging in, change directories:
```
root@c6cc601b0360:/# cd ca
root@c6cc601b0360:/ca#
```
Then connect to the database:
```
root@c6cc601b0360:/ca# sqlite3 fabric-ca-server.db
```
Run a test query:
```
root@c6cc601b0360:/ca# select * from users
```

Then connect to Hyperledger fabric CA DB by setting the path file name [](https://i.stack.imgur.com/6Ryek.png)
connect to the database then, without username\password if you keep default values, you will see the requested tables as shown below

The error is in the `dart.io` library used with [HTTPClientRequest](https://api.dartlang.org/stable/1.24.3/dart-io/IOSink-class.html) and the exception is in the line 176 [here](https://raw.githubusercontent.com/flutter/flutter/master/packages/flutter_tools/lib/src/base/io.dart).
I've no error using `http` on my `iOS emulator`. So I guess the problem is in your SDK version or in the data you are parsing. Or there is something wrong with your emulator... Have you tried on a real device?
Here my flutter version:
```
Flutter 0.1.5 • channel beta • https://github.com/flutter/flutter.git
Framework • revision 3ea4d06340 (5 weeks ago) • 2018-02-22 11:12:39 -0800
Engine • revision ead227f118
Tools • Dart 2.0.0-dev.28.0.flutter-0b4f01f759
```
You can try my example project [here](https://github.com/username_11/flutter_app_000006).
Please try it and let me know if it works or you get the same error.
Moreover type `flutter --version` and paste your output.

@"^Home/UserDetails?Code=(.*)", // RegEx to match Route
"Home/{$1}", // URL to rewrite route
skipRemainingRules: true // Should skip other rules

Upvotes: 4 [selected_answer]<issue_comment>username_2: Adding a rule to match `@"{$1}"` won't work. The term `$1` represents a value parsed using RegEx. You haven't executed any RegEx so you're effectively telling it to "rewrite my URL whenever the URL is `null`". Clearly, that isn't very likely.
You want to match the incoming URL using this regular expression:
```
@"^Home/UserDetails?Code=(\d+)"
```
The `(\d+)` tells RegEx to match "one or more digits" and store it as a variable. Since this is the only variable included in the parens, the value is stored in `$1`.
You then want to rewrite the URL using the value parsed using that regex:
```
"Home/$1"
```
You pass these two strings into the `AddRewrite` method:
```
AddRewrite(
@"^Home/UserDetails?Code=(\d+)", // RegEx to match URL
"Home/$1", // URL to rewrite
true // Stop processing any aditional rules
);

2018/03/21 | 1,008 | 2,846 | <issue_start>username_0: I have a relationship name `:RELTYPE` with a property array called `LineIds`.
Assume,
```
(node1)-[r:RELTYPE {LineIds : [1,2,15]}]->(node2)
```
I want to remove a very specific value from the `r.LineIds` array (let's say 15).
The code written doesn't seem to work. I am trying to remove "15" from the `r.LineIds` array.
```
var lineId = 15
var match = "(t:Template)-[r1:DEPENDS_ON]->(e:Template)"
this.client.Cypher.Match(match)
.Where((Template t) => t.Id == this.source.Id && t.ScenarioId == sid1)
.AndWhere((Segment e) => e.Id == this.dest.Id)
.Remove(lineId+" In r.LineIds")
.ExecuteWithoutResults();
```
In Neo4j Browser
```
match (b :Template)-[r:Temp_Reffered_DIM_SEG1]->(dim2 :Natural_Account)
where b.Id = 228 and b.ScenarioId = 200 and dim2.Id =117
remove 15 in r.LineIds
delete 15
```
I have also tried [15] instead of just 15 in the remove. Nothing seems to work. Can anyone please help me with the syntax?<issue_comment>username_1: As you can see the developer manual of neo4j where for [list operations](https://neo4j.com/docs/developer-manual/3.2/cypher/functions/list/) remove is not a function used for list but used to [remove](https://neo4j.com/docs/developer-manual/3.2/cypher/clauses/remove/) a property/label of a node.
Upvotes: 0 <issue_comment>username_2: Not surprising you're having trouble, there isn't a way in Cypher to selectively remove an item from a list. But you can replace the list with one that has the value filtered out.
With just Cypher, you can do this:
```
match (b :Template)-[r:Temp_Reffered_DIM_SEG1]->(dim2 :Natural_Account)
where b.Id = 228 and b.ScenarioId = 200 and dim2.Id =117
set r.LineIds = filter(val in r.LineIds where val <> 15)
```
If you have access to APOC Procedures, there's one that is a bit easier to use:
```
match (b :Template)-[r:Temp_Reffered_DIM_SEG1]->(dim2 :Natural_Account)
where b.Id = 228 and b.ScenarioId = 200 and dim2.Id =117
set r.LineIds = apoc.coll.removeAll(r.LineIds, [15])
```
Upvotes: 1 <issue_comment>username_3: I finally figured it out.
Filtering out the values that I wish to remove was one of the solution that worked for me.
The Query written below worked fine.
```
match (b :Template)-[r:Temp_Reffered_DIM_SEG1]->(dim2 :Natural_Account)
where b.Id = 228 and b.ScenarioId = 200 and dim2.Id =117
Set r.LineIds = filter(x in r.LineIds where not(x=15))
```
Code for calling Neo4j DB from .net class
```
var lineId = 15
var match = "(t:Template)-[r1:DEPENDS_ON]->(e:Template)"
this.client.Cypher.Match(match)
.Where((Template t) => t.Id == this.source.Id && t.ScenarioId == sid1)
.AndWhere((Segment e) => e.Id == this.dest.Id)
.Set(string.Format("r.LineIds = filter(x in r.LineIds where not(x={0}))",lineId))
.ExecuteWithoutResults();
```
Thats it.

2018/03/21 | 889 | 3,202 | <issue_start>username_0: Terraform can't find a resource which is declared in the same file where the reference is.
It seems that this line is causing trouble: `role_arn = "${aws_iam_role.newsapi_lambda_codepipeline.arn}"`. It can't find `newsapi_lambda_codepipeline` which is declared as `resource "aws_iam_role" "newsapi_lambda_codepipeline" { ... }`.
This is my main.tf:
```
resource "aws_s3_bucket" "newsapi_lambda_builds" {
bucket = "newsapi-lambda-builds"
acl = "private"
}
resource "aws_iam_role" "newsapi_lambda_codebuild" {
name = "newsapi-lambda-codebuild"
assume_role_policy = <
```
After executing `terraform apply` I get:
```
Error: Error running plan: 1 error(s) occurred:
* aws_codepipeline.newsapi_lambda: 1 error(s) occurred:
* aws_codepipeline.newsapi_lambda: Resource 'aws_iam_role.newsapi_lambda_codepipeline' not found for variable 'aws_iam_role.newsapi_lambda_codepipeline.arn'
```
I don't understand why that happens. I have `aws_iam_role.newsapi_lambda_codepipeline` declared, haven't I?<issue_comment>username_1: I believe your role declaration could be slightly wrong. And terraform was not able to generate an arn for that, therefore not found.
It looks like you also need to create `resource "aws_iam_role_policy"`. See <https://www.terraform.io/docs/providers/aws/r/codepipeline.html>
It's a bit unclear why you'd need to split.
If this is not the case, let me know and I'll try to run the code myself to test.
Upvotes: 4 [selected_answer]<issue_comment>username_2: For those experiencing an issue with `aws_ecs_task_definition` not finding a variable for the `aws_ecs_task_definition.XXX.arn`, there's a good chance your JSON came out malformed. Here's what I did to remedy my issue
* Replace your line with `task_definition = "[]"`
* Run `terraform plan`
At this point you should get an error. For example, I got
>
> module.tf.aws\_ecs\_task\_definition.sandbox: ECS Task Definition container\_definitions is invalid: Error decoding JSON: json: cannot unmarshal string into Go struct field ContainerDefinition.MemoryReservation of type int64
>
>
>
In this case, I had quoted `memSize` in my `template_file` and it didn't implicitly convert to int64, hence an error.
I changed `"memoryReservation": "${mem_size}"` to `"memoryReservation": ${mem_size}`, removed the task\_definition placeholder, and everything went smoothly.
Upvotes: 3 <issue_comment>username_3: Since the title of the problem is pretty generic, I landed on this link.
I was able to find the problem, given the fact that there is `something wrong with the resource which was not found and hence it is not getting created`
In my case it was a variable not getting referenced correctly in `aws_cloudwatch_event_rule` "event\_pattern" key
```
event_pattern = <
```

In my case (misconfigured reference to CIDR block from custom AWS VPC module), after running
```
terraform plan --target aws_security_group.something-or-other
```
Terraform actually provided clear error message on what exactly i did wrong this time.

why can't I also add it in the import array such as:
```
@NgModule({

Adding it in the import gives an error. Here is why I need Renderer2:
myComponent.html (part of my shared.module):
```
```
myComponent.ts
```
constructor(private renderer: Renderer2) {
}
const element = this.renderer.selectRootElement('#searchElem');
setTimeout(() => element.focus(), 0);
```
This is done to be able to set the focus of an element.<issue_comment>username_1: `Renderer2` is an injectable (service) part of Angular core. It's not a module. The [import property in `@NgModule` is to import other modules](https://angular.io/api/core/NgModule#imports). You should be able to use `Renderer2` in your component the way you have it, but simply remove it from the module imports.

imports
```
imports describe which dependencies this module has.
If your module depends on other modules, you list them here. example
```
imports: [
BrowserModule, HttpClientModule,DataTableModule, AppRoutingModule,
],
```
The short answer is that you put something in your NgModule’s imports if you’re going
to be using it in your *templates* or with *dependency injection*.
`import` statement is used to import other typescript files and class
```
import {className} from 'filePath';

2018/03/21 | 324 | 1,239 | <issue_start>username_0: Not entirely sure if this is possible but is there a way to start the specified cloud foundry instances in sequence rather than having them start concurrently?
Right now using the default cf push command with build-pack, 2 instances to be spun up. Would like to do this on the push if possible.
Any ideas if this is possible?
thanks,
Stefan<issue_comment>username_1: Based on `cf push --help`, that doesn't seem to be possible...
However, if your goal is to start instances in sequence, maybe the [`cf scale` command](https://docs.cloudfoundry.org/devguide/deploy-apps/cf-scale.html) is an option for you:
```
$ cf push myapp -i 1
$ cf scale myapp -i 2
```
You could wrap these commands plus some logic into a script that would start N instances sequentially.
Upvotes: 1 <issue_comment>username_2: I needed to run a poller, one instance of my app only - turns out I could do this by using the [`CF_INSTANCE_INDEX`](http://docs.cloudfoundry.org/devguide/deploy-apps/environment-variable.html#CF-INSTANCE-INDEX) environment variable and ensure that it only ran on one instance.
This negated the need for a hackier solution of a sequenced start of the instances and a lock file.

I split the lines with whitespace to get the words as a String array. Then if the words are not my unique words ArrayList, I add the word to the ArrayList. However, there is a couple of problems. The first one is that it also adds empty String to the unique words ArrayList. The second one is that it adds the same words 2 times, and when I compare those two Strings, it acts like they are not equal. My code is as follows:
```
ArrayList uniqueWords = new ArrayList<>();
Scanner scan = new Scanner(new File("input.txt"));
while(scan.hasNext())
{
String []line = scan.nextLine().split("\\s+");

2018/03/21 | 1,134 | 3,529 | <issue_start>username_0: hi, I have some issues with my real time plotting for matplotlib. I am using "time" on the X axis and a random number on Y axis. The random number is a static number then multiplied by a random number
```
import matplotlib.pyplot as plt
import datetime
import numpy as np
import time
def GetRandomInt(Data):
timerCount=0
x=[]
y=[]
while timerCount < 5000:
NewNumber = Data * np.random.randomint(5)
x.append(datetime.datetime.now())
y.append(NewNumber)
plt.plot(x,y)
plt.show()
time.sleep(10)
a = 10
GetRandomInt(a)
```
This seems to crash python as it cannot handle the updates - I can add a delay but wanted to know if the code is doing the right thing? I have cleaned the code to do the same function as my code, so the idea is we have some static data, then some data which we want to update every 5 seconds or so and then to plot the updates. Thanks!<issue_comment>username_1: You instantiate GetRandomInt which instantiates PlotData which instantiates GetRandomInt which instantiates PlotData which ... etc. This is the source of your problems.
Upvotes: 0 <issue_comment>username_2: To draw a continuous set of random line plots, you would need to use animation in matplotlib:
```
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
fig, ax = plt.subplots()
max_x = 5
max_rand = 10
x = np.arange(0, max_x)
ax.set_ylim(0, max_rand)
line, = ax.plot(x, np.random.randint(0, max_rand, max_x))
def init(): # give a clean slate to start
line.set_ydata([np.nan] * len(x))
return line,
def animate(i): # update the y values (every 1000ms)
line.set_ydata(np.random.randint(0, max_rand, max_x))
return line,
ani = animation.FuncAnimation(
fig, animate, init_func=init, interval=1000, blit=True, save_count=10)
plt.show()
```
[](https://i.stack.imgur.com/jD4CY.png)
The idea here is that you have a graph containing `x` and `y` values. Where `x`is just a range e.g. 0 to 5. You then call `animation.FuncAnimation()` which tells matplotlib to call your `animate()` function every `1000ms` to let you provide new `y` values.
You can speed this up as much as you like by modifying the `interval` parameter.
---
One possible approach if you wanted to plot values over time, you could use a `deque()` to hold the `y` values and then use the `x` axis to hold `seconds ago`:
```
from collections import deque
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
from matplotlib.ticker import FuncFormatter
def init():
line.set_ydata([np.nan] * len(x))
return line,
def animate(i):
# Add next value
data.append(np.random.randint(0, max_rand))
line.set_ydata(data)
plt.savefig('e:\\python temp\\fig_{:02}'.format(i))
print(i)
return line,
max_x = 10
max_rand = 5
data = deque(np.zeros(max_x), maxlen=max_x) # hold the last 10 values
x = np.arange(0, max_x)
fig, ax = plt.subplots()

```
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
fig, ax = plt.subplots()
max_x = 5
max_rand = 10
x = np.arange(0, max_x)
ax.set_ylim(0, max_rand)
line, = ax.plot(x, np.random.randint(0, max_rand, max_x))
def init(): # give a clean slate to start
line.set_ydata([np.nan] * len(x))
return line,
def animate(i): # update the y values (every 1000ms)
line.set_ydata(np.random.randint(0, max_rand, max_x))
return line,
ani = animation.FuncAnimation(
fig, animate, init_func=init, interval=1000, blit=True, save_count=10)
plt.show()
```
[](https://i.stack.imgur.com/jD4CY.png)
The idea here is that you have a graph containing `x` and `y` values. Where `x`is just a range e.g. 0 to 5. You then call `animation.FuncAnimation()` which tells matplotlib to call your `animate()` function every `1000ms` to let you provide new `y` values.
You can speed this up as much as you like by modifying the `interval` parameter.
---
One possible approach if you wanted to plot values over time, you could use a `deque()` to hold the `y` values and then use the `x` axis to hold `seconds ago`:
```
from collections import deque
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
from matplotlib.ticker import FuncFormatter
def init():
line.set_ydata([np.nan] * len(x))
return line,
def animate(i):
# Add next value
data.append(np.random.randint(0, max_rand))
line.set_ydata(data)
plt.savefig('e:\\python temp\\fig_{:02}'.format(i))
print(i)
return line,
max_x = 10
max_rand = 5
data = deque(np.zeros(max_x), maxlen=max_x) # hold the last 10 values
x = np.arange(0, max_x)
fig, ax = plt.subplots()
ax.set_ylim(0, max_rand)
ax.set_xlim(0, max_x-1)
line, = ax.plot(x, np.random.randint(0, max_rand, max_x))
ax.xaxis.set_major_formatter(FuncFormatter(lambda x, pos: '{:.0f}s'.format(max_x - x - 1)))
plt.xlabel('Seconds ago')
ani = animation.FuncAnimation(
fig, animate, init_func=init, interval=1000, blit=True, save_count=10)
plt.show()
```

2018/03/21 | 560 | 2,173 | <issue_start>username_0: i am starting a project i want know that what is the best and most accepted way of using angular as front end and laravel as back end
can i do like in view folder of laravel i will install angular is it ok??
i tried to create api for that and in angluar i will call that api.
what is the most used way for doing this i have seen tutorials over this but most of the tuts are for angular version 2 and its outdated
so can you please tell me any way to work laravel 5.6 and angular 5 or 4 together
please give me your suggestion and thoughts<issue_comment>username_1: I should stick with making an Laravel API and let your Angular app make calls to that API. This is the most common approach these days.
Upvotes: 1 <issue_comment>username_2: So basiclly there are two ways you can do this.
One keep everything in one app, and do as you suggested and put in /view. Laravel has a `php artisan preset react` which sets the application up for React, but as far as i know there is not one for angular but sure you can find a tutorial on how to include Angular in your Laravel project.
The second way is keeping them seperated having a Laravel/Lumen app that provides there API, and a another project that has the Angular project running, than your Angular project will be calling the Laravel's api through two seperate servers running on Localhost example. I just answered another simillar questions of the benefits of doing it like this.
Read it here: <https://stackoverflow.com/a/49181795/2783379>
Upvotes: 3 [selected_answer]<issue_comment>username_3: You can view the documenation page of angular and laravel.
I think, this is the best way and it can help you to achieve your project using the two technology.
<https://laravel-angular.io/>
Installation:
```
composer require jadjoubran/laravel-angular
```
If you're using Laravel 5.5 or newer, you can skip this step.
Inside your config/app.php, add the Service Provider:
```
Jadjoubran\LaravelAngular\Provider\LaravelServiceProvider::class
```
Then run the installation command:
```
php artisan laravelangular:install
```

2018/03/21 | 552 | 2,152 | <issue_start>username_0: I am quite new to docker. I worked a `Dockefile` that copies my project sources and them builds the application. The building process is quite complex and should be done in the container's environment; not the host machine.
So the Dockerfile look something like this:
```
FROM base-image
RUN mkdir -p /proj/branches/www
COPY ./proj/branches/mybranch/* /proj/branches/mybranch/
RUN chown root:www-data -R /proj
COPY config-and-build.sh .
RUN /config-and-build.sh
EXPOSE 80
CMD apachectl -D FOREGROUND
```
The project source folder is big (~3 G). And so, building the image takes a while; copying the files and compiling some sources. Most of the time I will not change the sources of the compiled programs so this is a waste of time.
I am trying to understand how volumes work to mount the sources. But my understanding is that the volume is defined at runtime, so the `config-and-build` script cannot be done.
Is there a way to get this done?<issue_comment>username_1: A quick way to make the source code available is to use [volume bind-mounts](https://docs.docker.com/storage/bind-mounts/). This will allow you to give the container access to a directory that is on the host machine.
You can achieve that via mounting the directory containing the source code using the `-v` argument when starting the container.
```
docker run -v : ...
```
The host directory and the container directory will be in sync, which will enable you to avoid rebuilding the image wherever there are new code changes.
Upvotes: 0 <issue_comment>username_2: You can add your script `config-and-build.sh` to ENTRYPOINT & integrate your CMD `apachectl -D FOREGROUND` in that entrypoint script itself.
Ref - <https://docs.docker.com/engine/reference/builder/#entrypoint>
Once that's done you can use host bind volumes `-v` with `docker run` to mount your project directory directly inside the container which will remove the dependency of copying project using the Dockerfile.

Using `.each()`, `$(HTMLElement)` to make `this` back into a jQuery object and `.children()` to find the `resp-container` you want to count.
```js
$(document).ready(function() {
var container = $(".container");
container.each(function() {
var items = $(this).children(".resp-container");
switch (items.length) {
case 1:
items.addClass("full-resp");
break;
case 2:
items.addClass("half-resp");
break;
case 3:
items.addClass("third-resp");
break;
case 4:
items.addClass("fourth-resp");
break;
default:
items.addClass("fourth-resp");
}
});

containers.forEach(container => {

const respContainers = container.querySelectorAll('.resp-container'); // ... get nodelist of child .resp-container divs
respContainers.forEach((rContainer, index) => {
if (index < classes.length) return rContainer.classList.add(classes[index]);
rContainer.classList.add(classes[classes.length - 1]); // if the index of the .resp-container div is larger than number of classes defined in classes array, add the last defined class to this element

2018/03/21 | 753 | 1,818 | <issue_start>username_0: I noticed that the base R `quantile` function does not support date arguments.
I appreciate that defining quantiles for dates needs care in the definitions (i.e. if you have 6 dates and ask for the 25th percentile, you need to define the suitable rounding).
Is there an efficient implementation of such a quantile function, either as a part of base or another package.
The following sample function achieves essentially what I am interested in (with some tweaking to handle the case of the 0'th percentile), but I imagine that more efficient implementations are possible.
```
#Date quantile function.
dquantile <- function(x, probs){
sx <- sort(x)
pos <- round( probs * length(x) )
return( sx[pos] )
}
# Example.
dates <- as.Date("01/01/1900", "%d/%m/%Y") + floor( 36500 * runif(100000) )
dquantile(dates, c(0.001, 0.025, 0.975, 0.999) )

2018/03/21 | 747 | 1,796 | <issue_start>username_0: I understand that when an APDU is issued through a smart card reader the result has a format like this:
```
[ [data], SW1, SW2 ]
```
I know that when you're issuing the APDU you can specify the size of the expected answer by using `Le` field but I'm wondering if there is any byte (or anything) within the data field that indicates its actual size.
For example, say that I want to read the master file:
First, I issue a `SELECT FILE` apdu:
```
00 A4 00 00
```
which would return `61 1b` for example, where `1b` is number of bytes to read using `GET RESPONSE`. Then I send the `GET RESPONSE` apdu using `Le` for the expected size of the answer:
```
00 C0 00 00 1B
```
And this returns `[ [00, 01, 02, ...], 90, 00 ]`.

As long as you don't need formatting/comments, objects can be read or dumped with [js-yaml](https://github.com/nodeca/js-yaml).
```
const yaml = require('js-yaml')
const fs = require('fs')
const kyaml = {
metadata: {
name: project_name,
service: service_name,
system: system_id,
app_version: project_version,
tier: 'app',
}
}
fs.writeFile('new.yaml', yaml.safeDump(kyaml), 'utf8', err => {
if (err) console.log(err)
})
```
Also you could possibly be doing things that [helm](https://docs.helm.sh/) can already do for you with [templates](https://docs.helm.sh/chart_template_guide/#the-chart-template-developer-s-guide).

Because YAML is a superset of JSON, `JSON.stringify` can be safely used as a valid YAML escape function.
Using Mustache templates, we ensure all templated values are escaped by setting the escape function:
```js
const mustache = require('mustache')
mustache.escape = JSON.stringify
mustache.render(template, vars)
```
Using Handlebars we can produce valid YAML by disabling the default escaping and providing a "json" helper:
```js
const handlebars = require('handlebars')
const render = handlebars.compile(template, { noEscape: true })
render(vars, {helpers: { json: JSON.stringify }}))
```
The json helper needs to be used in the YAML template any time a value may require escaping:
```
metadata:
name: {{json projectName}}
labels:
version: {{buildId}}
tier: app
```
Without appropriate YAML escaping there could be encoding errors in the generated YAML document if values contain newlines or YAML special characters like "|". Some templating engines (eg Mustache and Handlebars) will escape values with HTML encoding by default which will also produce encoding errors if HTML special characters are present in values (eg quote which is escaped as "'").

**How I want the use the data:**
I want to get all abilities and values from one player by using his player\_id as key. For example if I need the data from player 16, then I want to get (0, 56), (1,52), (2, 62)... or an array with int[] values = [56, 52, 62, 72, 64] for each player.
Now I want to save this data in a performant way. In PHP I would use an associative array. How could I do this in C#? (I have read some examples about dictionaries, but I am not able to use them for my problem. Maybe dictionaries are the wrong approach for this?)<issue_comment>username_1: Probably the easiest thing for the code you already have is to populate a `DataTable` which is an in-memory "table". It has rows and columns.
```
IDataReader reader = dbcmd.ExecuteReader();
DataTable dt = new DataTable();
dt.Load(reader);
```
>
> Update

>
Once you have a data table loaded you can convert the data to instances of Players (for instance).
Given these classes:
```
class PlayerDetails
{
public string AbilityID { get; set; }
public string Value { get; set; }
}
class Player
{
public string PlayerID { get; set; }
public List Details { get; set; }
}
```
You can obtain a `List` each with a `Details` property containing a `List`:
```
var groupedByPlayer = dt.AsEnumerable().GroupBy(d => d["player_id"]).Select(b => new
Player
{
PlayerID = b.Key.ToString(),
Details = b.Select(bp => new PlayerDetails
{
AbilityID = bp[1].ToString(),
Value = bp[2].ToString()
}).ToList()
});
```
That probably looks pretty ugly if you're not familiar with Linq but if you understand SQL GROUP BY it is similar except you end up with instances of your `Player` class.
Upvotes: 2 <issue_comment>username_2: You will need to define a data structure to hold your data.
A simple one would be a class that represents one line
```
public class Player
{
public int Id {get; set;}
public int Ability {get;set;}
public int Value {get;set;}
}
```
And add each row to a `List`.
However, then you would have 5 rows for each player.
Another option is a class for just Ability/Value
```
public class AbilityValue
{
public int Ability {get;set;}
public int Value {get;set;}
}
```
and store that in a `Dictionary>`. This needs some explaining:
* The key is the player\_id
* The value is a list of ability/value pairs that you read
The way to use this:
* read a row from the data
* see if you already have that key in your dictionary
* if so, add the new ability/value to that list
* if not, add a new item with the player\_id as key. Don't forget to initialize that list
If you know that "Ability" is always between 0 and 4, you could also use an array of size 5 as value of your dictionary. Then you use the ability as index into that array, to set the value.

```
public function __construct() {
$this->id = 'ry_ecpay_atm';
$this->has_fields = false;
$this->order_button_text = __('Pay via ATM', RY_WT::$textdomain);
$this->method_title = __('ECPay ATM', RY_WT::$textdomain);
$this->method_description = '';
```<issue_comment>username_1: This can be done with the following code *(where you will set your payment gateway IDs and the corresponding desired button text)*:
```
add_filter('woocommerce_order_button_text', 'custom_order_button_text' );
function custom_order_button_text( $order_button_text ) {
$default = __( 'Place order', 'woocommerce' ); // If needed
// Get the chosen payment gateway (dynamically)
$chosen_payment_method = WC()->session->get('chosen_payment_method');
// Set your payment gateways IDs in EACH "IF" statement
if( $chosen_payment_method == 'bacs'){
// HERE set your custom button text
$order_button_text = __( 'Bank wire payment', 'woocommerce' );
} elseif( $chosen_payment_method == 'ry_ecpay_atm'){
// HERE set your custom button text
$order_button_text = __( 'Place order via ECPay', 'woocommerce' );
}
// jQuery code: Make dynamic text button "on change" event ?>
(function($){
$('form.checkout').on( 'change', 'input[name^="payment\_method"]', function() {
var t = { updateTimer: !1, dirtyInput: !1,
reset\_update\_checkout\_timer: function() {
clearTimeout(t.updateTimer)
}, trigger\_update\_checkout: function() {
t.reset\_update\_checkout\_timer(), t.dirtyInput = !1,
$(document.body).trigger("update\_checkout")
}
};
t.trigger\_update\_checkout();
});
})(jQuery);
php
return $order_button_text;
}
</code
```
*Code goes in function.php file of your active child theme (or theme).* Tested and works.

```
add_filter('woocommerce_available_payment_gateways', 'change_barion_label');
function change_barion_label($gateways) {
if($gateways['ry_ecpay_atm']) {
$gateways['ry_ecpay_atm']->order_button_text = 'new label';
}
return $gateways;
}
```
WooCommerce runs this filter when loading the payment gateways, so it should work site-wide.

2018/03/21 | 1,922 | 6,835 | <issue_start>username_0: Hey I'm trying to get my ViewModel working, but no luck so far.
Android Studio shows error `Cannot resolve symbol 'ViewModelProviders'`.
Every other question I found on this topic was correcting `extends Activity` to `extends AppCompatActivity`, but I am extending the right one. Not sure what I'm missing...
My code is based on [This YouTube video](https://youtu.be/c9-057jC1ZA)
**MainActivity.java**
```
public class MainActivity extends AppCompatActivity implements
TileAdapter.TileAdapterOnClickHandler {
private BaseViewModel viewModel;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//set Toolbar
Toolbar myToolbar = findViewById(R.id.toolbar);
setSupportActionBar(myToolbar);
//initialize viewModel
viewModel = ViewModelProviders.of(this).get(BaseViewModel.class);
```
**BaseViewModel.java**
```
public class BaseViewModel extends ViewModel {
private Movie[] mMovie;
public void init (Movie[] movies){
this.mMovie = movies;
}
public Movie[] getMovie() {
return mMovie;
}
```<issue_comment>username_1: I didn't have both dependencies in my build, hence the problem.
```
implementation "android.arch.lifecycle:extensions:1.1.0"
implementation "android.arch.lifecycle:viewmodel:1.1.0"

```
dependencies {

Upvotes: 3 <issue_comment>username_8: I had the same problem. None of the other solutions helped me.
I realized that I was using `import androidx.lifecycle.ViewModelProvider;` instead of `import androidx.lifecycle.ViewModelProviders;`.
So make sure you are using `import androidx.lifecycle.ViewModelProviders;`. That is `ViewModelProviders` with an `s`.

```
MyViewModel myViewModel = new ViewModelProvider(this).get(MyViewModel.class);
```
it requires both of these:
```
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.lifecycle:lifecycle-extensions:2.2.0'
```
(alone with `lifecycle-extentions` is not sufficient)
Update
------
It seems that you have no longer to include the gradle implementation line (`'androidx.lifecycle:lifecycle-extensions:2.2.0'`) to instantiate `ViewModelProvider`.

```
register_post_type( 'cases',

**Create Metabox**
```
function add_your_fields_meta_box() {
add_meta_box(
'your_fields_meta_box', // $id
'Your Fields', // $title
'show_your_fields_meta_box', // $callback
'your_post', // $screen
'normal', // $context
'high' // $priority
);
}
add_action( 'add_meta_boxes', 'add_your_fields_meta_box' );
```
**Html part**
```
function show_your_fields_meta_box() {
global $post;
$meta = get_post_meta( $post->ID, 'your_fields', true ); ?>
php }
</code
```
**Save field in database**
```
function save_your_fields_meta( $post_id ) {
// verify nonce
if ( !wp_verify_nonce( $_POST['your_meta_box_nonce'], basename(__FILE__) ) ) {
return $post_id;
}
// check autosave
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) {
return $post_id;
}
// check permissions
if ( 'page' === $_POST['post_type'] ) {
if ( !current_user_can( 'edit_page', $post_id ) ) {
return $post_id;
} elseif ( !current_user_can( 'edit_post', $post_id ) ) {
return $post_id;
}
}
$old = get_post_meta( $post_id, 'your_fields', true );
$new = $_POST['your_fields'];
if ( $new && $new !== $old ) {
update_post_meta( $post_id, 'your_fields', $new );
} elseif ( '' === $new && $old ) {
delete_post_meta( $post_id, 'your_fields', $old );

}<issue_comment>username_1: It's a mess with Cordova plugins not specifying dependencies properly in their gradle build files (using different exact versions instead of +).
I'm using this another plugin [cordova-android-play-services-gradle-release](http://cordova-android-play-services-gradle-release) which somehow fixes the issue for me (ya...irony it works :D).
```
ionic cordova plugin add cordova-android-play-services-gradle-release
ionic cordova platform add android
ionic cordova platform remove android
```
Above commands will add this plugin, after which you need to re-add android platform.
Edit (other solution):
You can instead try editing the project.properties file with the latest or compatible version (11.+) if the above solution doesn't work
```
target=android-26
android.library.reference.1=CordovaLib
cordova.system.library.1=com.android.support:appcompat-v7:23+
cordova.gradle.include.1=com.synconset.imagepicker/myapp-ignorelinterrors.gradle
cordova.gradle.include.2=com.synconset.imagepicker/myapp-androidtarget.gradle
cordova.system.library.2=com.android.support:support-v4:24.1.1+

* [Disabling submit button until all fields have values](https://stackoverflow.com/questions/5614399/disabling-submit-button-until-all-fields-have-values)
* [Disable submit button until all form inputs have data](https://stackoverflow.com/questions/35590673/disable-submit-button-until-all-form-inputs-have-data)
But is there any way we can get check that all field types have values using jQuery? Including and fields?
Here's a [Codepen](https://codepen.io/abbasarezoo/pen/QmpzXQ) of a basic version of my form and here's my HTML:
```
Text field
Radio fields
Radio 1
Radio 2
Checkbox fields
Checkbox 1
Checkbox 2
Select options
Option A
Option B
Text area
```
Is this possible?<issue_comment>username_1: you can do like this with jQuery: (in codepen replace all your javascript with this code, I have tested it in your codepen)
```
$(function() {
$('.contact-form').on('input',':input',function() {
var inputs = $('.contact-form :input');
var num\_inputs = inputs.length;
var num\_filled = inputs.filter(function() { return !!this.value }).length;
$('.contact-form :submit').prop('disabled',(num\_filled<num\_inputs));
});
});
```
good luck!

1. In the next snippet, I assume ALL inputs (except radio buttons) have to be filled in before making the form submittable, which does not necessarily represent all real life scenarios.
2. As mentioned, radios (in this example only 2) are given a special treatment since only one per group can be selected.
3. Concerning s, one will be considered invalid if an empty option if selected (if one exists). In this example, your select tag always has a non-empty value, I added another to the markup to show its behavior.
Let me know if it works
```js
$(document).ready(function() {
$(":input").on('input', function(){validate();});
$(":input").on('change', function(){validate();});
});
function validate() {
var $submitButton = $("input[type=submit]");
var isValid = true;
if($(':checkbox:checked').length != $(':checkbox').length)
isValid = false;
else if($(':radio:checked').length == 0)
isValid = false;
else{
$('input:text, textarea').each(function() {
if($(this).val() == ''){
isValid = false;
return false;
}
});
if(isValid){
$('select').each(function() {
if($(this).val() == ''){
isValid = false;
return false;
}
});
}
}
$submitButton.prop("disabled", !isValid);
}
```
```css
.contact-form {
width: 400px;
margin: 50px;
}
.contact-form__row {
padding: 0 0 10px;
margin: 0 0 10px;
border-bottom: 1px solid grey;
}
p {
font-weight: bold;
}

2018/03/21 | 857 | 3,037 | <issue_start>username_0: i am using mongoengine to integrate with flask , i wanted to know how to get document object id every time i try i get `File "/var/www/flask_projects/iot_mongo/app.py", line 244, in post return jsonify(user.id) AttributeError: 'BaseQuerySet' object has no attribute 'id'`
```
class Test(Resource):
def post(self):
parser = reqparse.RequestParser()
parser.add_argument('email',required=True, help='email')
args=parser.parse_args()
user=AdminUser.objects(email=args['email'])
return jsonify(user.id)
api.add_resource(Test,'/test')
if __name__ == '__main__':
app.run(debug=True)
```<issue_comment>username_1: Check out [the documentation](http://docs.mongoengine.org/apireference.html#), [`Document.objects`](http://docs.mongoengine.org/apireference.html#Document.objects) is a [`QuerySet`](http://docs.mongoengine.org/apireference.html#mongoengine.queryset.QuerySet) object.
You seem to be expecting that this part of your code
```
user=AdminUser.objects(email=args['email']) # user will be a QuerySet
```
will give you a single result, which is not the case, it will give you a `QuerySet` with zero or more results. It does not have an attribute `id`, this is why you get the error message you are seeing when you try to access this attribute here:
```
return jsonify(user.id) # QuerySet does not have the attribute id
```
You need to fetch the actual result(s) you want from it, assuming you are sure your query will return a single result, or do not care that there might be more than one result and just want the first one, you probably want something along these lines:
```
user=AdminUser.objects(email=args['email']).first() # extract first result
return jsonfiy(user)
```
Alernatively, returning all results would look like this:
```
users=AdminUser.objects(email=args['email']).all() # extract all results
return jsonfiy(users)
```
Upvotes: 1 <issue_comment>username_2: I've been doing this. An example User model would be like~
```
class User(Document):
first_name = StringField(required=True, max_length=50)
last_name = StringField(required=True, max_length=50)
username = StringField(required=True)
password = StringField(required=True, min_length=6)
def to_json(self):
return {
"_id": str(self.pk),
"first_name": self.first_name,
"last_name": self.last_name,
"username": self.username,
"password": <PASSWORD>
}
```
I convert the id to a string. I would then get a single object with~
```
user = User.objects.get(pk=user_id)
return user.to_json()
```
for a whole object, but if I just want the id I would do...
```
user.pk()
```
I created my own to\_json method that converts the primary key to a string because otherwise it would return "id": ObjectID("SomeID") instead of neatly printing "id": "SomeID".
Hope this helps!
If you want to find someone by email I suggest~
```
User.objects.get(email=args['email'])
```

2018/03/21 | 807 | 3,342 | <issue_start>username_0: It is known that exact mathematical strategies such MILP are not efficient for large instances of the flexible job shop problem. However, still, nowadays it is possible to find proposals of MILP formulations for the FJS problem. It may be due to the fact that it is interesting to use the MILP model for experiments involving non-exact methods as metaheuristics (GA, FA, TS, etc) since it provides lower bounds.
I also read that CP should be chosen when finding a feasible solution is more important than an optimal solution. Is that a true statement?<issue_comment>username_1: What you said is about right.
For some types of problems it is hard to construct an efficient MILP model to solve them, and they are better off being solved by metaheuristics. However, if a LP can be constructed in a way as to provide a tight and non-trivial bound to a problem then it would be possible to verify if the solution of a good metaheuristic reaches optimality or near-optimality. This means that you can (potentially) solve some instances of some types of NP problems to optimality using only linear programming and metaheuristics.
As for CP, it is very good at finding if a problem is feasible (or proving that it is infeasible). CP *can* be used to find optimal solutions, but it is not its strong suit and MILP usually does better in that regard.

I think that this statement is becoming less and less true with the recent progress of CP. Especially for scheduling problems. For instance you mention the flexible job-shop scheduling problem. On this problem, generic CP techniques were used to improve and close many of the open instances of the classical benchmarks (both by finding better solutions and by finding tighter lower bounds). See for instance [1]. In this article, the same CP techniques are used to improve/close many other classical scheduling problems (in particular several variants of job-shop and RCPSP).
And, yes, CP can provide some lower bounds. If you add the constraint “objective < K” and the search proves this problem is infeasible, then K is a lower bound. It is also to be noted that some modern CP solvers use linear relaxations to guide the search and provide some lower bounds.
You can also have a look at [2] for a comparison of the performance of several MIP models and a CP model for the massively studied job-shop scheduling problem.
And if you are interested in a more complete view of how different CP techniques can be integrated in a generic CP-based optimization engine, there is also this very recent article [3] (<http://ibm.biz/Constraints2018>).

2018/03/21 | 1,278 | 3,749 | <issue_start>username_0: I'm trying to build a page where people can select the colour and capacity of a product. Only one colour/capacity can be active at a given time and when one has been selected a border needs to appear around it.
You can see in my attempt below the problem of the other elements being displaced when the border is applied.
[](https://i.stack.imgur.com/tsJqY.png)
I thought about giving all the elements `border: 2px solid rgba(0,0,0,0)` to resolve the displacing issue then using javascript to change the border properties on click, but I think this is probably not an elegant solution.
Here is the HTML...
```
*
*
*
```
and the CSS...
```
ul li {
width: 47px;
height: 47px;
border-radius: 12px;
border: 2px solid rgba(0,0,0,0);
padding: 3px;
}
.select-colour {
width: 45px;
height: 45px;
border-radius: 8px;
border: 1px solid #c2bebb;
-webkit-box-shadow: inset 0px -99px 46px -86px rgba(0,0,0,0.42);
-moz-box-shadow: inset 0px -99px 46px -86px rgba(0,0,0,0.42);
box-shadow: inset 0px -99px 46px -86px rgba(0,0,0,0.42);
}
#gold {
background-color: #f5e7dc;
}
#silver {
background-color: #e2e2e2;
}
#space-grey {
background-color: #232323;
}
```
Does anyone have any ideas about the best way to approach this? Thanks.<issue_comment>username_1: Add `box-sizing: border-box` to the `ul li` selector like this:
```
ul li {
width: 47px;
height: 47px;
border-radius: 12px;
border: 2px solid rgba(0,0,0,0);
padding: 3px;
box-sizing: border-box;
}
```
Box sizing: border-box makes the element total width/height include the border and radius.

input[type="checkbox"]:checked ~ #hello{
box-shadow: 0 0 0 3px hotpink;
}
#hello{

This is what you want a hidden check box

2018/03/21 | 903 | 2,824 | <issue_start>username_0: I have a vector of strings and want to add a + before each word in each string.
```
strings <- c('string one', 'string two', 'string three')
strings_new <- str_replace_all(strings, "\\b\\w", '+')
string_new
```
Unfortunately, this is replacing the first character, not adding the + symbol. I'm not too familiar with regex to know how to solve this.
Any help would be great.
Thanks<issue_comment>username_1: Using captured groups is one way of doing this. Group with parenthesis and recall with `\\1`.
```
strings_new <- str_replace_all(strings, "(\\b\\w)", '+\\1')
strings_new
[1] "+string +one" "+string +two" "+string +three"
```
Upvotes: 4 [selected_answer]<issue_comment>username_2: You may use a **base R** solution using PCRE regex `[[:<:]]` that matches the *starting word boundary*, a location between a non-word and a word char:
```
strings <- c('string one', 'string two', 'string three')
gsub("[[:<:]]", "+", strings, perl=TRUE)
# => [1] "+string +one" "+string +two" "+string +three"
```
Or, you may use a `(\w+)` (that matches and captures into Group 1 any one or more word chars, i.e. letters, digits, or `_`) TRE regex to replace with a `+` and a replacement backreference `\1` to restore the consumed chars in the output:
```
gsub("(\\w+)", '+\\1', strings)
# => [1] "+string +one" "+string +two" "+string +three"
```
Note you do not need a word boundary here since the first word char matched will be already at the word boundary and the consequent word chars will be consumed due to `+` quantifier. See the [regex demo](https://regex101.com/r/dRdsAp/1).
And with an ICU regex based `str_replace_all`, you may use
```
> str_replace_all(strings, "\\w+", '+\\0')
[1] "+string +one" "+string +two" "+string +three"
```
The `\\0` is a replacement backreference to the whole match.
Upvotes: 2 <issue_comment>username_3: Another alternative would be to use `strsplit()` in combination with `paste0()`:
```
res <- lapply(strsplit(strings, " "), function(x) paste0("+", x))
sapply(res, paste0, collapse = " ")
# [1] "+string +one" "+string +two" "+string +three"
```
For some people the advantage may be that you don't have to wrestle with a regular expression. However, I would always prefer the direct regex statements by Jasbner and Wictor
Upvotes: 0 <issue_comment>username_4: You can do this without capture groups as well (as others have shown) by using the regex `\b(?=\w)` with `perl=T` as shown below.
[See code in use here](https://tio.run/##K/r/v7ikKDMvvVjBRlchWUMdwlPIz0tV11GA8UrK85F5GUWpqeqaXOnFpUkaSjExSRr2tjEx5ZpKOgpK2kACaqCOQkFqUY5tiOb//wA)
```
strings <- c('string one', 'string two', 'string three')
gsub("\\b(?=\\w)", "+", strings, perl=T)
```
Result
```
[1] "+string +one" "+string +two" "+string +three"
```

2018/03/21 | 3,868 | 18,953 | <issue_start>username_0: In my case, I have Java 1.6 and want to connect to a remote server which only supports TLS1.2. Server URL is: <https://blagajne-test.fu.gov.si:9002> and certificate public key is here: <http://datoteke.durs.gov.si/dpr/files/test-tls.cer>

Currently have:
```
var mySwiper = new Swiper ('#my-swiper', {
slidesPerView: 3,
slidesPerColumn: 2,
spaceBetween: 30,
speed: 2000,
loop: true,
autoplay: {
delay: 1000,
disableOnInteraction: false,
},
```
Several others have ran into a similar issue but not clear solution. One noted they added to help resolve the issue:
```
setTimeout(function(){
mySwiper.update(true);
mySwiper.slideTo(0, 0)
}, 100);
```
Tried adding after the above code block but they there is no motion at all. If I added it inside the above code block then it shows one large thumbnail per slide vs 6. Any thoughts?<issue_comment>username_1: Please switch to Version 1.55 this will fix the issue...

2018/03/21 | 744 | 2,079 | <issue_start>username_0: I have a txt file with a number of dates, each signifying an event:
```
15MAR18 103000
15MAR18 120518
17MAR18 121203
17MAR18 134443
17MAR18 151733
19MAR18 165013
19MAR18 182253
19MAR18 195533
```
I am trying to get a running tally of how many 'events' occur within a 24 hour time period.
I can read the file and parse into datetime objects ok:
```
for line in range(0, len(event_list):
eventTime = event_list[line][:14]
eventTime = datetime.strptime(eventTime, '%d%b%y %H%M%S')
eventTime_next = event_list[line+1][:14]
eventTime_next = datetime.strptime(next, '%d%b%y %H%M%S')
```
I don't know how to next go about it.
I tried to compare the line ahead with the previous and but I don't think that's the way to go about it.
I need it so the following happens
```
15MAR18 103000 1
15MAR18 120518 2
17MAR18 121203 1
17MAR18 134443 2
17MAR18 151733 3
19MAR18 165013 1
19MAR18 182253 2
19MAR18 195533 3
```
I.e So the count will go back to 1 when 24 hours has elapsed since the first comparison... and then start again with the new start reference.
I hope this makes sense?
Or is this something for pandas library or something?<issue_comment>username_1: Please switch to Version 1.55 this will fix the issue...

2018/03/21 | 324 | 1,074 | <issue_start>username_0: I have been scratching my head with this one and wonder if anybody would be kind enough to give me a pointer. I am extracting some data as a variable from JSON to PHP, and I can do this no problem when there are nested nodes - IF the node is a text but not if the node is a number. I am using json\_decode
THIS IS NOT THE SAME AS How do I extract data from JSON with PHP?
This is ok
```
$get_temp = $jsonobj->main->temp;
```
This is not working
```
$get_weather = $jsonobj->main->0->weather;
```
So my question is how do I target the node when it is a number?
Thanks<issue_comment>username_1: Probabily you have an array into main node.. so you can get its value with an index like this:
```
$get_weather = $jsonobj->main[0]->weather;
```
Where `0` is the index that you want to get
Upvotes: 2 <issue_comment>username_2: ```
$get_weather = $jsonobj->main[$x]->weather;

**$x** would be the index

app.use('/register', session, register);
app.use('/login', session, login);
```
to
```
app.use('/register', register);
app.use('/login', login);
```

**updated:**
try update your code of setup session store by this example
```
var session = require('express-session');
var FileStore = require('session-file-store')(session);
app.use(session({
store: new FileStore(options),
...
}));
```
if still not work, `express-session` has a default session store, use the default session store and check if there still a compiler error.

2018/03/21 | 688 | 2,346 | <issue_start>username_0: I have a csv where for one column values are in list of dict like below
```
[{'10': 'i ve been with what is now comcast since 2001 the company has really grown and improved and delivers a great service along with great customer service ', 'aspects':['service']},
{'20': 'good service but lack of options to allow it be more affordable allowing individual channel choices would be great ', 'aspects':['lack', 'service']},
{'30': 'it a good service but very expensive', 'aspects':['service']}, {'40': 'good service', 'aspects':['service']},
{'50': 'good service but over priced ', 'aspects':['service']}]
```
Now because when I am reading this from `CSV` its a `string` I am not able to convert it to original type of `list of dict` and then `json` .
How I can actually achieve this .
Solution :
```
data = output[output.aspects == aspect]['column1'].tolist()
listData=ast.literal_eval(data[0])
return json.dumps(listData)
```<issue_comment>username_1: You can use the `ast` module
**Ex:**
```
import ast
s = """[{'10': 'i ve been with what is now comcast since 2001 the company has really grown and improved and delivers a great service along with great customer service ', 'aspects':['service']},
{'20': 'good service but lack of options to allow it be more affordable allowing individual channel choices would be great ', 'aspects':['lack', 'service']},
{'30': 'it a good service but very expensive', 'aspects':['service']}, {'40': 'good service', 'aspects':['service']},
{'50': 'good service but over priced ', 'aspects':['service']}]"""
print(ast.literal_eval(s))
```
**Output:**
```
[{'10': 'i ve been with what is now comcast since 2001 the company has really grown and improved and delivers a great service along with great customer service ', 'aspects': ['service']}, {'aspects': ['lack', 'service'], '20': 'good service but lack of options to allow it be more affordable allowing individual channel choices would be great '}, {'30': 'it a good service but very expensive', 'aspects': ['service']}, {'aspects': ['service'], '40': 'good service'}, {'aspects': ['service'], '50': 'good service but over priced '}]

```js
class Foo {}
namespace Bar
{
export const Qux = Foo;
}
let a: Bar.Qux;
```<issue_comment>username_1: The `Qux` in your implementation is a variable rather than a type.
Therefore, the code below is valid:
```
class Foo {}
namespace Bar {
export const Qux = Foo;
}
let a = Bar.Qux;
```
If you like to use `Qux` as an `interface` or extended `class`, you can do:
```
class Foo {}
namespace Bar {
export class Qux extends Foo {}
}
let a = new Bar.Qux();
```
Does this solve your problem?
Upvotes: 0 <issue_comment>username_2: You are exporting a constant, not a type. You can do this `let a = new Bar.Foo()`, and `a` will be of type Foo.
If you want to export both a type and a constant:
```
namespace Bar
{
export const Qux = Foo;
export type Qux = Foo;
}
```
Then you can have:
```
let a: Bar.Qux = new Bar.Qux();
```
TypeScript will determine, based on context, if you are using the type definition or the constant.

Can someone tell me what I am doing wrong and how I could pass the component to the function correctly?<issue_comment>username_1: As Ferry stated, this refers to a component, not the function. therefor the component should be provided to the ssjs function e.g. this.getParent().

2018/03/21 | 1,212 | 3,351 | <issue_start>username_0: i have a dictionary as
```
count = {'lt60': {'a': 0, 'b': 0, 'c': 0, 'd': 0}, 'ge60le90': {'a': 4, 'b': 0, 'C': 0, 'd': 0}, 'gt90': {'a': 0, 'b': 1, 'c': 2, 'd': 1} }
```
i want to write this dictionary in a CSV format like this ..as you can see in this picture [](https://i.stack.imgur.com/8DOuG.png)
what i want is pic the keys from lt60, ge60le90, gt90 and want to write them in a row. like i pick 'a' and its value from all the nested dictionaries and write its value in that row.<issue_comment>username_1: You can use `pandas` to do this:
```
import pandas as pd
count = {'lt60': {'a': 0, 'b': 0, 'c': 0, 'd': 0},
'ge60le90': {'a': 4, 'b': 0, 'c': 0, 'd': 0},
'gt90': {'a': 0, 'b': 1, 'c': 2, 'd': 1} }
df = pd.DataFrame(count).rename_axis('relation_type').reset_index()
df = df.rename(columns={'ge60le90': 'confidence<90',
'gt90': 'confidence>90',
'lt60': 'confidence<60'})
df.to_csv('out.csv', index=False)
# relation_type confidence<90 confidence>90 confidence<60
# 0 a 4 0 0
# 1 b 0 1 0
# 2 c 0 2 0
# 3 d 0 1 0
```

```
count = {'lt60': {'a': 0, 'b': 0, 'c': 0, 'd': 0},
'ge60le90': {'a': 4, 'b': 0, 'c': 0, 'd': 0},
'gt90': {'a': 0, 'b': 1, 'c': 2, 'd': 1} }
# Create outfile
f = open("C:\\Users\\\\Desktop\\OUT.csv","w")
# Write first row
f.write(",a,b,c,d\n")
# Iterate through keys
for keys in count:
print(keys)
f.write(keys + ",")
KEYS = count[keys]
# Iterate though values
for values in KEYS:
print(KEYS[values])
f.write(str(KEYS[values]) + ",")
f.write("\n")
f.close()
```

```
import csv
lookup = {'ge60le90': 'confidence<90','gt90': 'confidence>90', 'lt60': 'confidence<60'}
count = {'lt60': {'a': 0, 'b': 0, 'c': 0, 'd': 0}, 'ge60le90': {'a': 4, 'b': 0, 'c': 0, 'd': 0}, 'gt90': {'a': 0, 'b': 1, 'c': 2, 'd': 1} }
# Getting keys from dictionary that match them with titles below.
rowKeys = [k for k in count['lt60'].keys()]
titles = [['relation type'] + list(lookup[k] for k in count.keys())]
# Getting all row variable values for every title.
rows = [[count[k][i] for k in count.keys()] for i in rowKeys]
# Concatenating variables and values.
fields = [[rowKeys[i]] + rows[i] for i in range(len(rowKeys))]
# Concatenating final output to be written to file.
result = titles + fields
print("Final result to be written: ")
for r in result:
print(r)
# Writing to file.
with open("output.csv", "w", newline="") as outFile:
writer = csv.writer(outFile, delimiter=';',quotechar='|', quoting=csv.QUOTE_MINIMAL)
writer.writerows(result)
```
Note that the `;` delimiter works for European Windows and might not work for you. In this case, use `,` instead.

2018/03/21 | 742 | 2,311 | <issue_start>username_0: I have conflicts between the default key mappings of plugin jedi-vim and my customized key mapping.
```
" I mapped some cscope functions like below
nnoremap g :cscope find g =expand('')
nnoremap d :cscope find d =expand('')
```
However, this key binding is overridden by the key binding of `g:jedi#goto_assignments_command` and in `g:jedi#goto_command` jedi-vim.
I am wondering if it is possible to set a distinct for jedi-vim only instead of re-mapping conflicted keys.<issue_comment>username_1: Apparently jedi-vim doesn't use the canonical -mappings, but separate configuration variables. Nonetheless
```
let g:jedi#goto_assignments_command = ",g"
let g:jedi#goto_command = ",d"
```
in your `~/.vimrc` (i.e. before jedi-vim is sourced) should do the trick, and this is what I would recommend.
### Alternative
The key is influenced by the `mapleader` variable. From [`:help`](https://vimhelp.appspot.com/map.txt.html#<Leader>) :
>
> Note that the value of "mapleader" is used at the moment the mapping is
> defined. Changing "mapleader" after that has no effect for already defined
> mappings.
>

So, you could also solve it this way:
```
let mapleader = ','
runtime! plugin/jedi.vim
unlet mapleader
```
Plugin managers or installing as a *pack plugin* further complicate this, and it changes the ordering of plugin initialization. I do not recommend this.

```
:let g:jedi#goto_command = ",jd"
:let g:jedi#goto_assignments_command = ",jg"
:let g:jedi#usages_command = ",jn"
:let g:jedi#rename_command = ",jr"
" will auto-create next visual-map: ,jr *@:call jedi#rename_visual()
" rename\_command() fails in normal-mode, but success in visual-mode !
:let g:jedi#goto\_stubs\_command = ",js"
:let g:jedi#documentation\_command = ",jK"
" s \*@'c'.jedi#complete\_string(0)
:let g:jedi#completions\_command = ""
" jedi-vim Plug called AFTER remaping its commands only
Plug 'davidhalter/jedi-vim', {'for': 'python'}
```
PD: this should be a comment of Mr. Karkat answer, but still not 50 points.
