COPR 是个人软件仓库[集合](https://copr.fedorainfracloud.org/)，它不在 Fedora 中。这是因为某些软件不符合轻松打包的标准；或者它可能不符合其他 Fedora 标准，尽管它是自由而开源的。COPR 可以在 Fedora 套件之外提供这些项目。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，这是一种尝试新的或实验性的软件的一种巧妙的方式。


本文介绍了 COPR 中一些有趣的新项目。如果你第一次使用 COPR，请参阅 [COPR 用户文档](https://docs.pagure.org/copr.copr/user_documentation.html#)。


### Contrast


[Contrast](https://gitlab.gnome.org/World/design/contrast) 是一款小应用，用于检查两种颜色之间的对比度并确定其是否满足 [WCAG](https://www.w3.org/WAI/standards-guidelines/wcag/) 中指定的要求。可以使用十六进制 RGB 代码或使用颜色选择器选择颜色。除了显示对比度之外，Contrast 还以选定的颜色为背景上显示短文本来显示比较。

#### 安装说明


[仓库](https://copr.fedorainfracloud.org/coprs/atim/contrast/)当前为 Fedora 31 和 Rawhide 提供了 Contrast。要安装 Contrast，请使用以下命令：



```
sudo dnf copr enable atim/contrast
sudo dnf install contrast
```

### Pamixer


[Pamixer](https://github.com/cdemoulins/pamixer) 是一个使用 PulseAudio 调整和监控声音设备音量的命令行工具。你可以显示设备的当前音量并直接增加/减小它，或静音/取消静音。Pamixer 可以列出所有源和接收器。


#### 安装说明


[仓库](https://copr.fedorainfracloud.org/coprs/atim/contrast/)当前为 Fedora 31 和 Rawhide 提供了 Pamixer。要安装 Pamixer，请使用以下命令：



```
sudo dnf copr enable opuk/pamixer
sudo dnf install pamixer
```

### PhotoFlare


[PhotoFlare](https://photoflare.io/) 是一款图像编辑器。它有简单且布局合理的用户界面，其中的大多数功能都可在工具栏中使用。尽管它不支持使用图层，但 PhotoFlare 提供了诸如各种颜色调整、图像变换、滤镜、画笔和自动裁剪等功能。此外，PhotoFlare 可以批量编辑图片，来对所有图片应用相同的滤镜和转换，并将结果保存在指定目录中。

```

### Tdiff


[Tdiff](https://github.com/F-i-f/tdiff) 是用于比较两个文件树的命令行工具。除了显示某些文件或目录仅存在于一棵树中之外，tdiff 还显示文件大小、类型和内容，所有者用户和组 ID、权限、修改时间等方面的差异。


#### 安装说明


[仓库](https://copr.fedorainfracloud.org/coprs/atim/contrast/)当前为 Fedora 29-31、Rawhide、EPEL 6-8 和其他发行版提供了 tdiff。要安装 tdiff，请使用以下命令：

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.

This article presents a few new and interesting projects in COPR. If you’re new to using COPR, see the [COPR User Documentation](https://docs.pagure.org/copr.copr/user_documentation.html#) for how to get started.

### Contrast

[Contrast](https://gitlab.gnome.org/World/design/contrast) is a small app used for checking contrast between two colors and to determine if it meets the requirements specified in [WCAG](https://www.w3.org/WAI/standards-guidelines/wcag/). The colors can be selected either using their RGB hex codes or with a color picker tool. In addition to showing the contrast ratio, Contrast displays a short text on a background in selected colors to demonstrate comparison.

#### Installation instructions

The [repo](https://copr.fedorainfracloud.org/coprs/atim/contrast/) currently provides contrast for Fedora 31 and Rawhide. To install Contrast, use these commands:

sudo dnf copr enable atim/contrast sudo dnf install contrast

### Pamixer

[Pamixer](https://github.com/cdemoulins/pamixer) is a command-line tool for adjusting and monitoring volume levels of sound devices using PulseAudio. You can display the current volume of a device and either set it directly or increase/decrease it, or (un)mute it. Pamixer can list all sources and sinks.

#### Installation instructions

The [repo](https://copr.fedorainfracloud.org/coprs/opuk/pamixer/) currently provides Pamixer for Fedora 31 and Rawhide. To install Pamixer, use these commands:

sudo dnf copr enable opuk/pamixer sudo dnf install pamixer

### PhotoFlare

[PhotoFlare](https://photoflare.io/) is an image editor. It has a simple and well-arranged user interface, where most of the features are available in the toolbars. PhotoFlare provides features such as various color adjustments, image transformations, filters, brushes and automatic cropping, although it doesn’t support working with layers. Also, PhotoFlare can edit pictures in batches, applying the same filters and transformations on all pictures and storing the results in a specified directory.

#### Installation instructions

The [repo](https://copr.fedorainfracloud.org/coprs/adriend/photoflare/) currently provides PhotoFlare for Fedora 31. To install Photoflare, use these commands:

sudo dnf copr enable adriend/photoflare sudo dnf install photoflare

### Tdiff

[Tdiff](https://github.com/F-i-f/tdiff) is a command-line tool for comparing two file trees. In addition to showing that some files or directories exist in one tree only, tdiff shows differences in file sizes, types and contents, owner user and group ids, permissions, modification time and more.

#### Installation instructions

The [repo](https://copr.fedorainfracloud.org/coprs/fif/tdiff/) currently provides tdiff for Fedora 29-31 and Rawhide, EPEL 6-8 and other distributions. To install tdiff, use these commands:

sudo dnf copr enable fif/tdiff sudo dnf install tdiff

## Thomas Klein

Nice picks! Thank you Dominik.

## Yann

Thanks for your articles. Always interesting.

A suggestion for the next one :

https://copr.fedorainfracloud.org/coprs/ycollet/linuxmao/

A repository dedicated to music and computer.

I am the owner of this repo.

## Silvia

Installing Photo Flare. Let’s see how it goes. Thanks!
