如何使'git diff'忽略注释 [英] How to make 'git diff' ignore comments

问题描述

我正在尝试生成在特定提交中更改的文件的列表。问题是，每个文件在文件顶部的注释中都具有版本号-并且由于此提交引入了新版本，这意味着每个文件都已更改。

I am trying to produce a list of the files that were changed in a specific commit. The problem is, that every file has the version number in a comment at the top of the file - and since this commit introduces a new version, that means that every file has changed.

我不在乎更改的注释，因此我想让 git diff 忽略所有与 ^ ＼匹配的行＼s * \ *。* $ ，因为这些都是注释（/ * * /的一部分）。

I don't care about the changed comments, so I would like to have git diff ignore all lines that match ^\s*\*.*$, as these are all comments (part of /* */).

我找不到任何方法 git diff 忽略特定的行。

I cannot find any way to tell git diff to ignore specific lines.

我已经尝试设置textconv属性，以使Git在将文件进行区分之前将文件传递给sed。 ，以便sed可以删除有问题的行-问题在于， git diff --name-status 实际上并不比较文件，只是比较散列，

I have already tried setting a textconv attribute to cause Git to pass the files to sed before diffing them, so that sed can strip out the offending lines - the problem with this, is that git diff --name-status does not actually diff the files, just compares the hashes, and of course all the hashes have changed.

有没有办法做到这一点？

Is there a way to do this?

推荐答案

git diff -G <regex>

并指定一个不与您的版本号行不匹配的正则表达式。

And specify a regular expression that does not match your version number line.
