使用Uncrustify格式化你的代码

使用Uncrustify格式化你的代码

介绍

1. Uncrustify为一个支持C, C++, C#, Objective-C, D, Java, Pawn、VALA的代码格式化工具
2. 项目地址：https://github.com/uncrustify/uncrustify
3. 下载地址：https://github.com/uncrustify/uncrustify/tags
4. Uncrustify自定义风格可以使用基于web的uncrustify_config配置工具进行生成:https://cdanu.github.io/uncrustify_config_preview/index.html

使用

1. Uncrustify安装：从https://github.com/uncrustify/uncrustify/tags下载最新版本（0.72.0）

   $ mkdir build
   $ cd build
   $ cmake ..
   $ sudo make install
   

2. Uncrustify配置:

   • ​ 打开QtCreator,点击菜单栏“Help > About Plugins > C++ > Beautifier ”菜单项

• ​ 选中“Enable auto format on file save”，选择Tool为“Uncrustify”。在Uncrustify选项页，选择Uncrustify命令程序所在的路径：/usr/local/bin/uncrustify

• 选中“Use customized style”，点击Add按钮，增加一种自定义风格,将以下代码(https://paste.ubuntu.com/p/Q9NBxCHZs8/)粘贴进去。自定义风格可参见https://github.com/uncrustify/uncrustify/blob/master/etc/gnu-indent.cfg

  在打开“Tools > Options > Environment->Keyboard->Uncrustify->FormatFile”，可以设置格式化的快捷键,当你使用快捷键或者Ctrl + S保存代码后，Uncrustify将会以配置文件的风格统一你的代码；
