clojurians | clojure | any parser will have that information | 2017-11-17T19:47:20.000043 | Rebeca |
clojurians | clojure | it just depends on if you can get at it | 2017-11-17T19:47:32.000042 | Rebeca |
clojurians | clojure | grammars tend to be thought of as recognizers of languages, but they are also recipes that can be used to generate strings that are members of a language | 2017-11-17T19:48:16.000218 | Rebeca |
clojurians | clojure | the parsing with derivatives stuff spec's parser is based on seems like it would be really good for that stuff, but spec doesn't do partial parses, and finding some protocol for communicating where you want the parse to stop, and how you when to generate possible completions of the parse might be tricky | 2017-11-17T19:49:45.000138 | Rebeca |
clojurians | clojure | <@Rebeca>: really? I thought for most parsers, on incomplete strings, it's okay to just barf and say "this fails somewhere" | 2017-11-17T19:52:04.000198 | Berry |
clojurians | clojure | sure | 2017-11-17T19:52:24.000195 | Rebeca |
clojurians | clojure | Earley one of the few parsers I know of where the algorithm makes it blatantly clare what values are valid for next token give current prefix | 2017-11-17T19:52:37.000145 | Berry |
clojurians | clojure | In particular, I believe this is one of the main advantages of Earley over CYK or Packrat for parsing CFGs. | 2017-11-17T19:52:56.000184 | Berry |
clojurians | clojure | that is just because most other parser libraries don't provide meta information about the structure of the grammar they represent | 2017-11-17T19:53:47.000062 | Rebeca |
clojurians | clojure | the information is encoded in the structure of the parser, but it is hard to get at it | 2017-11-17T19:54:04.000144 | Rebeca |
clojurians | clojure | I'm not convinced that is true, but I can't disprove it either. | 2017-11-17T19:54:25.000060 | Berry |
clojurians | clojure | Is there a way to *get* the validator function of an atom ? I'm trying to create a spec that asserts: this atom has the following validator functikon. | 2017-11-17T19:55:58.000124 | Berry |
clojurians | clojure | <https://clojuredocs.org/clojure.core/get-validator> | 2017-11-17T20:01:28.000147 | Berry |
clojurians | clojure | why is `atom` in core, but `atom?` in clojure.inspector ?
<https://clojuredocs.org/clojure.inspector/atom_q>
Is there some other way I should be checking if an object is an atom ? | 2017-11-17T20:07:11.000017 | Berry |
clojurians | clojure | `#(instance? clojure.lang.Atom %)` ? | 2017-11-17T20:08:14.000005 | Raul |
clojurians | clojure | anybody use clojure or clojurescript to write iOS apps that use the audio engine? I'm interested to see if I can port one of my apps to clj/cljs | 2017-11-17T21:27:08.000050 | Magda |
clojurians | clojure | ```
(defn atom? [obj]
(instance? clojure.lang.Atom obj))
```
works for clojure. In cljs, how do I check if an object is an atom ? | 2017-11-17T22:57:18.000064 | Berry |
clojurians | clojure | <@Berry> A guess but I would imagine it'll be a protocol and you can use `satisfies?` on it... | 2017-11-17T23:21:43.000077 | Daniell |
clojurians | clojure | Hmm, no, apparently `(instance? Atom obj)` -- `cljs.core.Atom` according to the Replete iOS app. | 2017-11-17T23:25:08.000004 | Daniell |
clojurians | clojure | there's an "IAtom" somewhere in the source, but I wasn't sure how to include it | 2017-11-17T23:35:32.000077 | Berry |
clojurians | clojure | the full, appearing to work code, in case anyone else wants it, is:
```
(defn atom? [obj]
(instance?
#?(:clj clojure.lang.Atom
:cljs cljs.core.Atom)
obj))
``` | 2017-11-17T23:39:39.000086 | Berry |
clojurians | clojure | hello all, I'm storing some information on a atom and, in the end, I have this atom *data* `(type data) => clojure.lang.Atom` that, when I put @ become `(type @data) => clojure.lang.PersistentVector`. I need to convert this PersistentVector(ou the original atom) into a json array. Is there a built-in way of doing this? | 2017-11-18T00:59:22.000059 | Bettyann |
clojurians | clojure | there are two popular json libraries - cheshire and clojure.data.json | 2017-11-18T01:00:13.000073 | Margaret |
clojurians | clojure | there's nothing built in | 2017-11-18T01:00:19.000023 | Margaret |
clojurians | clojure | nothing canonical I could do to avoid add any lib? any loop specific strucutre or somethig? | 2017-11-18T01:01:14.000071 | Bettyann |
clojurians | clojure | neither the jvm nor clojure itself comes with a json generator, you need a library (even if you write that library yourself, which I don't recommend) | 2017-11-18T01:02:11.000010 | Margaret |
clojurians | clojure | json is not the problem as I'm using a ring middleware to convert, the problem is that PersistentVector doesn't provide a valid json array, due to the lack of comma or something | 2017-11-18T01:04:21.000004 | Bettyann |
clojurians | clojure | this is my real problem | 2017-11-18T01:04:40.000066 | Bettyann |
clojurians | clojure | you are using the middleware wrong then | 2017-11-18T01:05:30.000007 | Margaret |
clojurians | clojure | is there any built-in convertion instruction for persistentVector? | 2017-11-18T01:05:32.000002 | Bettyann |
clojurians | clojure | the vector is not the problem | 2017-11-18T01:05:34.000044 | Margaret |
clojurians | clojure | if commas aren't coming out, you aren't generating json | 2017-11-18T01:05:55.000016 | Margaret |
clojurians | clojure | if a write { :structures "like that" } a valid json comes out. But { :information *any-persistentVector* } not | 2017-11-18T01:06:59.000038 | Bettyann |
clojurians | clojure | that's not my experience of wrap-json at all | 2017-11-18T01:07:22.000012 | Margaret |
clojurians | clojure | something else is wrong here | 2017-11-18T01:07:28.000081 | Margaret |
clojurians | clojure | (unless there's been a regression and you are somehow the first one to see it) | 2017-11-18T01:08:05.000033 | Margaret |
clojurians | clojure | well, when I do what I wrote, I got something like `{"information": [{:index 0, :data 1} {:index 1, :data 100}] }` the problem of commas are related only to vector elements, not every element internally | 2017-11-18T01:10:31.000074 | Bettyann |
clojurians | clojure | I've been trying a lot of conversions the whole day but nothing worked | 2017-11-18T01:10:49.000014 | Bettyann |
clojurians | clojure | the only way I could see getting that result is if somebody called str on the vector before it was passed to the middleware | 2017-11-18T01:11:52.000021 | Margaret |
clojurians | clojure | because the middleware uses a proper json generator that wouldn't do that | 2017-11-18T01:12:11.000016 | Margaret |
clojurians | clojure | ```
(str @block)
=> "[{:index 0, :data 100} {:index 1, :data 500 }]"
``` | 2017-11-18T01:14:20.000013 | Bettyann |
clojurians | clojure | <@Bettyann> here's a REPL session showing that `ring-json/wrap-json-response` works as expected: ```boot.user=> (require '[ring.middleware.json :as json])
nil
boot.user=> (defn handler [req] {:body [1 2 3 4] :status 200 :headers {}})
#'boot.user/handler
boot.user=> (defn app (json/wrap-json-
json/wrap-json-body json/wrap-json-params json/wrap-json-response
boot.user=> (app {})
{:body "[1,2,3,4]", :status 200, :headers {"Content-Type" "application/json; charset=utf-8"}}``` Note that the response -- the `:body` -- needs to be a _vector_ *not* `(str some-vector)` | 2017-11-18T01:14:59.000061 | Daniell |
clojurians | clojure | Don't call `str` on the vector. | 2017-11-18T01:15:16.000010 | Daniell |
clojurians | clojure | Here's another example (using `ring.util.response/resp`): ```boot.user=> (require '[ring.util.response :as resp])
nil
boot.user=> (defn handler [req] (-> (resp/response {:my-vector ["I" "am" "a" "vector"]}) (resp/status 200)))
#'boot.user/handler
boot.user=> (def app (json/wrap-json-response handler))
#'boot.user/app
boot.user=> (app {})
{:status 200, :headers {"Content-Type" "application/json; charset=utf-8"}, :body "{\"my-vector\":[\"I\",\"am\",\"a\",\"vector\"]}"}``` | 2017-11-18T01:17:02.000007 | Daniell |
clojurians | clojure | I'm doing something like that:
```
(defn output-json
[information]
{:status 200
:headers {"Content-Type" "application/json"}
:body information })
(defn show-data
[]
(output-json {:length (count @core/data) :chain (str @core/data)} ))
``` | 2017-11-18T01:17:02.000056 | Bettyann |
clojurians | clojure | _Don't call `str`!_ | 2017-11-18T01:17:13.000035 | Daniell |
clojurians | clojure | ok, let me try | 2017-11-18T01:17:24.000094 | Bettyann |
clojurians | clojure | <@Bettyann> you are doing exactly the thing I said would cause your bug | 2017-11-18T01:17:30.000033 | Margaret |
clojurians | clojure | yup, the str. That damn str was driving me crazy | 2017-11-18T01:20:45.000046 | Bettyann |
clojurians | clojure | thank you | 2017-11-18T01:20:53.000037 | Bettyann |
clojurians | clojure | <@Bettyann> BTW, welcome to Clojurians! I saw you just joined half an hour ago. | 2017-11-18T01:21:54.000051 | Daniell |
clojurians | clojure | Are you new to Clojure? Or did you just find out about us? | 2017-11-18T01:22:14.000047 | Daniell |
clojurians | clojure | Thank you! And yes, I just found about this slack | 2017-11-18T01:22:32.000053 | Bettyann |
clojurians | clojure | I'm actually from erlang | 2017-11-18T01:22:46.000060 | Bettyann |
clojurians | clojure | joining a clojure project on my work | 2017-11-18T01:23:01.000004 | Bettyann |
clojurians | clojure | Oh cool. The Functional Prolog LOL :laughing: | 2017-11-18T01:23:01.000042 | Daniell |
clojurians | clojure | lol | 2017-11-18T01:23:06.000005 | Bettyann |
clojurians | clojure | clojure is awesome | 2017-11-18T01:23:18.000062 | Bettyann |
clojurians | clojure | I'm just having some small issues to get used | 2017-11-18T01:23:37.000003 | Bettyann |
clojurians | clojure | I did a lot of Prolog back in the day, and I did an Erlang workshop at Lambda Jam a few years ago. Interesting language. | 2017-11-18T01:23:37.000011 | Daniell |
clojurians | clojure | I work with payment processing in erlang | 2017-11-18T01:24:08.000006 | Bettyann |
clojurians | clojure | is nice, works well and I write new things in LFE(lisp flavored erlang). This led us to start some clojure experiments | 2017-11-18T01:24:51.000009 | Bettyann |
clojurians | clojure | and, well, JVM got my boss heart | 2017-11-18T01:25:05.000006 | Bettyann |
clojurians | clojure | and we are rewriting somethings in clojure, to check if we can go with this | 2017-11-18T01:26:03.000039 | Bettyann |
clojurians | clojure | I rather go with clojure than elixir | 2017-11-18T01:26:14.000027 | Bettyann |
clojurians | clojure | Pure erlang is no longer an option as is not too easy to find programmers | 2017-11-18T01:27:02.000030 | Bettyann |
clojurians | clojure | And BEAM is an island. The JVM opens a lot more doors. | 2017-11-18T01:27:23.000082 | Daniell |
clojurians | clojure | yup, this is the main point | 2017-11-18T01:27:45.000030 | Bettyann |
clojurians | clojure | and clojure is nice to code with, you feel productive | 2017-11-18T01:28:08.000011 | Bettyann |
clojurians | clojure | (don't get me wrong: BEAM is a _great_ island, but I don't know how broad that "church" will ever be... Erlang, LFE, Elixir) | 2017-11-18T01:28:23.000049 | Daniell |
clojurians | clojure | yup, this is true. BEAM is great, but JVM is a world | 2017-11-18T01:28:49.000038 | Bettyann |
clojurians | clojure | I've been on the JVM since '97... Java, Groovy, Scala, Clojure... and, would you believe, among all of that: CFML on the JVM too :slightly_smiling_face: | 2017-11-18T01:29:14.000012 | Daniell |
clojurians | clojure | ColdFusion or the open source engine Lucee | 2017-11-18T01:29:25.000059 | Daniell |
clojurians | clojure | lol didn't even know there was cfml on jvm | 2017-11-18T01:29:56.000033 | Bettyann |
clojurians | clojure | Most people don't. | 2017-11-18T01:30:23.000037 | Daniell |
clojurians | clojure | JVM is battle tested, the banks that we have to interface with use it, so is just natural | 2017-11-18T01:30:51.000064 | Bettyann |
clojurians | clojure | BEAM is good, really really good | 2017-11-18T01:31:15.000046 | Bettyann |
clojurians | clojure | and we have a lot of lobby for elixir here | 2017-11-18T01:31:25.000064 | Bettyann |
clojurians | clojure | as the creator, jose valim, is from here | 2017-11-18T01:31:35.000003 | Bettyann |
clojurians | clojure | I'm from Brazil, btw | 2017-11-18T01:31:45.000033 | Bettyann |
clojurians | clojure | and his company, plataformatec, try to make people use elixir | 2017-11-18T01:32:06.000012 | Bettyann |
clojurians | clojure | I guess there's always <https://github.com/trifork/erjang/wiki> and JRuby :slightly_smiling_face: | 2017-11-18T01:32:16.000006 | Daniell |
clojurians | clojure | lol | 2017-11-18T01:32:36.000037 | Bettyann |
clojurians | clojure | It's late for you in Brazil (or early, depending on how you look at it) | 2017-11-18T01:32:46.000048 | Daniell |
clojurians | clojure | 3:32am | 2017-11-18T01:32:56.000034 | Bettyann |
clojurians | clojure | 10:23pm here in San Francisco | 2017-11-18T01:33:09.000060 | Daniell |
clojurians | clojure | haha nice | 2017-11-18T01:33:17.000052 | Bettyann |
clojurians | clojure | but is common for us to be online this time at friday/saturday. We grab some beers, go code in a beach or any pool, and this hour we start to fell human again | 2017-11-18T01:34:51.000048 | Bettyann |
clojurians | clojure | :beers: | 2017-11-18T01:35:20.000009 | Daniell |
clojurians | clojure | I was trying to get some pictires but I'm too drunk lol | 2017-11-18T01:41:00.000068 | Bettyann |
clojurians | clojure | well, thank you guys, see you later. You are awesome | 2017-11-18T01:41:22.000032 | Bettyann |
clojurians | clojure | Hello developers,
i have now been using spacemacs for my clojure development since last 4 months but there is one feature which i am still not able to configure.
That is auto-complete for inbuilt library functions,
eg. when i type fil then it should already suggest me filter or any other functions available for it
Currently i have installed auto-completion layer in my spacemacs
and set (global-company-mode t) which enables dumb auto-complete everywhere
that is now when i type anything if that function or variable name is used previously only then it will suggest me, its not smart.
I have did alot of research and read ac-cider gives it but it shows now its depricated and i am not able to configure it in my spacemacs.
I have been stuggling for this since long now and i am pretty sure someone might have configured this in there setup can anyone help me out.?? | 2017-11-18T02:09:08.000020 | Jenee |
clojurians | clojure | How you guys manage `Errors` and `Failures` in `Clojure`. of course in `functional way`. | 2017-11-18T09:22:10.000048 | Olen |
clojurians | clojure | Anyone in Hong Kong? | 2017-11-18T09:27:31.000052 | Tien |
clojurians | clojure | Hmm, why does Clojure accept doubles as array indices? `(aget (into-array [1 2 3]) 0.1)` | 2017-11-18T10:26:38.000060 | Johana |
clojurians | clojure | <@Johana> Not an answer to your question, but this is the one last difference that we could ideally patch up in ClojureScript in order to make behavior be consistent. (We can't round down right now without breaking code that is misusing `aget` by passing property names.) | 2017-11-18T10:28:22.000050 | Dirk |
clojurians | clojure | That’s exactly where my question comes from (reacting on your twitter announcement) | 2017-11-18T10:28:46.000046 | Johana |
clojurians | clojure | I would rather have `aget` accept strings than doubles :joy: | 2017-11-18T10:29:09.000025 | Johana |
clojurians | clojure | Yeah, if the entire ClojureScript community used `:checked-access` then we could conceivably safely fix things by adding an inexpensive operation to round down. | 2017-11-18T10:29:38.000036 | Dirk |
clojurians | clojure | It’s no big deal switching to `goog.object`. But why on earth would you pass doubles when you want ints. It seems a bug to me. | 2017-11-18T10:30:09.000176 | Johana |
