git - Git中忽略目录的Unignore子目录

Question

假设我忽略了一个目录，但我想取消忽略其中的特定子目录。所以我有设置:

/uploads/
/uploads/rubbish/
/uploads/rubbish/stuff/KEEP_ME/
/uploads/foo/
/uploads/foo/bar/lose/

我想忽略除 KEEP_ME 目录之外的所有内容。我希望忽略看起来像:

/uploads/*
!/uploads/rubbish/stuff/KEEP_ME/

但这行不通，同一主题的多个排列也行不通。

一个有效的是

/uploads/**/**/**/
!/uploads/rubbish/stuff/KEEP_ME/

但这感觉有点局限和冗长？

Answer 1

根据 pattern format section of the gitignore documentation :

An optional prefix "!" which negates the pattern; any matching file excluded by a previous pattern will become included again. It is not possible to re-include a file if a parent directory of that file is excluded. Git doesn’t list excluded directories for performance reasons, so any patterns on contained files have no effect, no matter where they are defined. Put a backslash ("\") in front of the first "!" for patterns that begin with a literal "!", for example, "!important!.txt".

因此，先前排除的父目录 /uploads/rubbish/stuff/keep/ 模式必须在否定其内容之前完全否定:

#ignore everything within /uploads/ 
/uploads/*

#include everything within /uploads/rubbish/stuff/keep
!/uploads/rubbish/stuff/keep/  
!/uploads/rubbish/stuff/keep/*

要在 /uploads/rubbish/stuff/keep/ 中包含子目录，请添加第三行:

!/uploads/rubbish/stuff/keep/**/*
