Visual Studio
在扩展-》管理扩展-》联机-》搜索Format on Save (for VS2022)插件,并安装
安装需要关闭VS,安装后重新打开vs。
这样每次保存源文件时就会自动调用vs默认的clang-format.exe对源码进行缩进,空格等进行格式化
如果想使用自定义的格式对源码进行格式化,需要自定义一个.clang-format文件放在工程文件根目录下,则每次保存会自动使用.clang-format文件中的格式对代码进行格式调整
如果不想要这个功能可以禁用插件并重启VS
VS Code
在左侧Extensions中搜索Clang-format,点击安装
打开首选项设置(ctrl + ,),搜索format ,勾选format on save 自动保存
如果想要自定义格式也可以和visual studio一样在项目目录下编写.clang-format文件
.clang-format
.clang-format文件可以通过clang-format.exe生成,也可以自己写
