扩展正则表达式（ERE）.gitignore [英] Extended regular expressions (ERE) for .gitignore

问题描述

有没有在 .gitignore 文件中使用扩展正则表达式（ERE）的方法？例如，我想在 .gitignore 文件中使用 + 重复字符。有没有办法做到这一点？

解决方案

如图所示这里，并在这个问题中详细说明， fnmatch（）涉及解释glob模式，这意味着不支持正则表达式。 p>

这就是 gitignore 手册页提及：

否则， git将模式视为（3）与 FNM_PATHNAME 标记一起使用的shell glob：模式中的通配符不会匹配 / 在路径名中。

例如， Documentation / *。html 匹配文档/git.html 但不是 Documentati on / ppc / ppc.html 或 tools / perf / Documentation / perf.html 。

您可以在那些 问题。

Is there a way to use extended regular expressions(ERE) in a .gitignore file? For example I want to use the + repetition character in a .gitignore file. Is there a way to do that?

解决方案

As illustrated here and detailed in "this question", the function fnmatch() is involved to interpret glob patterns, which means regular expressions are not supported.

This is what gitignore man page mentions:

Otherwise, git treats the pattern as a shell glob suitable for consumption by fnmatch(3) with the FNM_PATHNAME flag: wildcards in the pattern will not match a / in the pathname.
For example, "Documentation/*.html" matches "Documentation/git.html" but not "Documentation/ppc/ppc.html" or "tools/perf/Documentation/perf.html".

You can see some correspondence between glob patterns and regular expressions in those questions.
