Git忽略BOM(防止git diff显示字节顺序标记更改) [英] Git ignore BOM (prevent git diff from showing byte order mark changes)

问题描述

我希望git diff不显示 BOM 更改.
此类更改通常在差异中显示为<feff>

I want git diff to not show BOM changes.
Such changes typically show up as <feff> in the diff:

-<feff>/*^M
+/*^M

如何使git diff表现为这种方式?
最好带有命令行参数.

How can I make git diff to behave this way?
Preferably with a command-line parameter.

git --ignore-all-space(又名git -w)不能解决问题. 如果重要的话，我使用的是Mac OS X.

git --ignore-all-space (aka git -w) does not do the trick. I am on Mac OS X if that matters.

推荐答案

使用Git属性过滤器

一种可能的解决方案是创建BOM表过滤器，例如:

One possible solution would be to create a BOM filter such as:

#!/bin/bash
sed '1s/^\xEF\xBB\xBF//' "$1"

将其存储在路径中的某个位置(例如removebom)并使其可执行.

store it somewhere in your path (as i.e. removebom) and make it executable.

然后，您需要通过运行以下命令在Git中配置过滤器:

Then you need to configure the filter in Git by running:

$ git config diff.removebom.textconv removebom

并向存储库中添加您感兴趣的文件(即cpp)的属性:

and adding an attribute for files you are interested in (i.e. cpp) to your repository:

*.cpp diff=removebom

作为.gitattributes文件.

或一次删除BOM表

...，因为希望您的项目中的BOM可以一劳永逸地删除:)

... because, hopefully, the BOM may be removed once and for all in your project :)
