COPR 是软件的个人存储库的[集合](https://copr.fedorainfracloud.org/)，它包含那些不在标准的 Fedora 仓库中的软件。某些软件不符合允许轻松打包的标准。或者它可能不符合其他 Fedora 标准，尽管它是自由开源的。COPR 可以在标准的 Fedora 包之外提供这些项目。COPR 中的软件不受 Fedora 基础设施的支持，或者是由项目自己背书的。但是，它是尝试新的或实验性软件的一种很好的方法。


这是 COPR 中一组新的有趣项目。


### MindForger


[MindForger](https://www.mindforger.com/) 是一个 Markdown 编辑器和笔记本。除了你预期的 Markdown 编辑器的功能之外，MindForger 还允许你将单个文件拆分为多个笔记。组织笔记并在文件之间移动、搜索它们都很容易。我已经使用 MindForger 一段时间来记录学习笔记了，现在可以在 COPR 中找到它啦。

#### 安装说明


该仓库目前在 Fedora 29 和 Rawhide 中提供 MindForger。要安装 MindForger，请使用以下命令：



```
sudo dnf copr enable deadmozay/mindforger
sudo dnf install mindforger
```

### Clingo


[Clingo](https://potassco.org/clingo/) 是使用[回答集编程](https://en.wikipedia.org/wiki/Answer_set_programming)（ASP）建模语言解决逻辑问题的程序。使用 ASP，你可以将问题声明为一个逻辑程序，然后 Clingo 来解决。最后，Clingo 以逻辑模型的形式产生问题的解决方案，称为回答集。


#### 安装说明


该仓库目前为 Fedora 28 和 29 提供 Clingo。要安装 Clingo，请使用以下命令：



```
sudo dnf copr enable timn/clingo
sudo dnf install clingo
```

### SGVrecord


[SGVrecord](https://github.com/yucefsourani/sgvrecord) 是一个用于录制屏幕的简单工具。它允许你捕获整个屏幕或仅选择其中的一部分。此外，有没有声音都可以进行录制。SGVrecord 以 WebM 格式生成文件。

OK
COPR is a [collection](https://copr.fedorainfracloud.org/) of personal repositories for software that isn’t carried in Fedora. Some software doesn’t conform to standards that allow easy packaging. Or it may not meet other Fedora standards, despite being free and open source. COPR can offer these projects outside the Fedora set of packages. Software in COPR isn’t supported by Fedora infrastructure or signed by the project. However, it can be a neat way to try new or experimental software.

Here’s a set of new and interesting projects in COPR.


### MindForger

[MindForger](https://www.mindforger.com/) is a Markdown editor and a notebook. In addition to features you’d expect from a Markdown editor, MindForger lets you split a single file into multiple notes. It’s easy to organize the notes and move them around between files, as well as search through them. I’ve been using MindForger for some time for my study notes, so it’s nice that it’s available through COPR now.

#### Installation instructions

The repo currently provides MindForger for Fedora 29 and Rawhide. To install MindForger, use these commands:

sudo dnf copr enable deadmozay/mindforger sudo dnf install mindforger

### Clingo

[Clingo](https://potassco.org/clingo/) is a program for solving logical problems using [answer set programming](https://en.wikipedia.org/wiki/Answer_set_programming) (ASP) modeling language. With ASP, you can declaratively describe a problem as a logical program that Clingo then solves. As a result, Clingo produces solutions to the problem in the form of logical models, called answer sets.

#### Installation instructions

The repo currently provides Clingo for Fedora 28 and 29. To install Clingo, use these commands:

sudo dnf copr enable timn/clingo sudo dnf install clingo

### SGVrecord

[SGVrecord](https://github.com/yucefsourani/sgvrecord) is a simple tool for recording your screen. It allows you to either capture the whole screen or select just a part of it. Furthermore, it is possible to make the record with or without sound. Sgvrecord produces files in WebM format.

#### Installation instructions

The repo currently provides SGVrecord for Fedora 28, 29, and Rawhide. To install SGVrecord, use these commands:

sudo dnf copr enable youssefmsourani/sgvrecord sudo dnf install sgvrecord

### Watchman

[Watchman](https://facebook.github.io/watchman/) is a service for monitoring and recording when changes are done to files.

You can specify directory trees for Watchman to monitor, as well as define actions

that are triggered when specified files are changed.

#### Installation instructions

The repo currently provides Watchman for Fedora 29 and Rawhide. To install Watchman, use these commands:

sudo dnf copr enable eklitzke/watchman sudo dnf install watchman

I’m excited about MindForger but I’m getting library errors right off the bat. It installed with no errors but it fails to launch. Running it from bash shows complaints about missing libQt5WebChannel. I found that library and installed it but now it’s complaining about libQt5Positioning. I haven’t gone beyond that yet, but I think there is a missing Qt package with all the qt libraries that need to be installed before the MindForger package.

## Nathan

I got it to run but it consumes 90% CPU while it’s running and causes my fans to go crazy, I ran strace on it and it’s apparently the RECVMSG syscall over and over again

$ strace -p 9879 -c

Why bother about CORP, when strictly forbidden by FEDORA? We can certainly do with out it! Why invite trouble by installing non recommended packages. There must be equally others in Fedora to consider. I like Fedora as it is. Long live FEDORA!

## Miroslav Suchý

@svs Copr does not contain packages forbidden by Fedora. It contains (mostly) packages where packager does not want to push it to Fedora. Usually because it does not meet Fedora packaging standard, packager do not want to dedicate much time for packaging, he does not want to react on security issues, he does not want to follow new releases, the software is too old or too new. There are plenty of reasons.

MindForger is pretty cool but I installed from the RPM in their git downloads. I’ve had issues with COPR repos lately because the maintainers aren’t neglecting to keep them updated. 🙁
