.gitignore中的否定模式如何工作？ [英] How do negated patterns work in .gitignore?

问题描述

我试图使用带有否定模式的.gitignore文件（以！开头！），但它不能按我期望的方式工作。

，我有以下的目录结构：

  C：/ gittest 
  -  .gitignore 
  - aaa / 
  -  bbb / 
  -  file.txt 
  -  ccc / 
  -  otherfile.txt 
  

在我的gitignore文件中，我有这个：

  aaa / 
！aaa / ccc / 
  

我的理解（基于这个文档页面）是文件aaa / ccc / otherfile.txt不应该被忽略，但实际上git忽略了一切

我是否误解了这句话：一个可选的前缀！否定了模式;任何匹配的文件被先前的模式排除在外。？

顺便说一下，这是Windows上的msysgit 1.7.0.2。

  
 > aaa / * 
！aaa / ccc 
  

您告诉它不要查看 aaa ，所以它甚至不检查路径 aaa / ccc 。如果使用通配符，它​​仍然会读取 aaa 的内容，那么每个条目都与通配符匹配并被忽略，除 aaa / ccc 将其放回。

I am attempting to use a .gitignore file with negated patterns (lines starting with !), but it's not working the way I expect.

As a minimal example, I have the folllowing directory structure:

C:/gittest
 -- .gitignore
 -- aaa/
   -- bbb/
     -- file.txt
   -- ccc/
     -- otherfile.txt

and in my gitignore file, I have this:

aaa/
!aaa/ccc/

My understanding (based on this doc page) is that the file aaa/ccc/otherfile.txt should not be ignored, but in fact git is ignoring everything under aaa.

Am I misunderstanding this sentence: "An optional prefix ! which negates the pattern; any matching file excluded by a previous pattern will become included again."?

BTW, this is on Windows with msysgit 1.7.0.2.

解决方案

I think that what you actually want to do is:

aaa/*
!aaa/ccc

You're telling it "don't look in aaa" so it never even examines the path aaa/ccc. If you use the wildcard, it still reads the contents of aaa, then each entry matches the wildcard and is ignored, except aaa/ccc which gets put back in.
