因为很多程序员使用node。满足这个问题的用例是排除node_modules，除了一个模块module-a，例如:

!node_modules/

node_modules/*
!node_modules/module-a/

我发现只有这个可行。

**/node_modules/*
!**/node_modules/keep-dir

这是另一个遍历目录结构以获得所需内容的示例。注意:我没有排除Library/，而是排除Library/**/*

# .gitignore file
Library/**/*
!Library/Application Support/
!Library/Application Support/Sublime Text 3/
!Library/Application Support/Sublime Text 3/Packages/
!Library/Application Support/Sublime Text 3/Packages/User/
!Library/Application Support/Sublime Text 3/Packages/User/*macro
!Library/Application Support/Sublime Text 3/Packages/User/*snippet
!Library/Application Support/Sublime Text 3/Packages/User/*settings
!Library/Application Support/Sublime Text 3/Packages/User/*keymap
!Library/Application Support/Sublime Text 3/Packages/User/*theme
!Library/Application Support/Sublime Text 3/Packages/User/**/
!Library/Application Support/Sublime Text 3/Packages/User/**/*macro
!Library/Application Support/Sublime Text 3/Packages/User/**/*snippet
!Library/Application Support/Sublime Text 3/Packages/User/**/*settings
!Library/Application Support/Sublime Text 3/Packages/User/**/*keymap
!Library/Application Support/Sublime Text 3/Packages/User/**/*theme

添加一个额外的答案:

!/.vs/              <== include this folder to source control, folder only, nothing else
/.vs/*              <== but ignore all files and sub-folder inside this folder
!/.vs/ProjectSettings.json <== but include this file to source control
!/.vs/config/       <== then include this folder to source control, folder only, nothing else
!/.vs/config/*      <== then include all files inside the folder

结果如下:

我的JetBrains IntelliJ IDEA .gitignore配置，在那里我需要排除整个。IDEA文件夹除了。IDEA /runConfigurations:

.idea
!.idea/
.idea/*
!.idea/runConfigurations/

因为很多程序员使用node。满足这个问题的用例是排除node_modules，除了一个模块module-a，例如:

!node_modules/

node_modules/*
!node_modules/module-a/
