Git：删除diff中的前后加/减行 [英] Git: remove leading plus/minus from lines in diff

问题描述

我的问题很简单，虽然我没有找到答案的运气。

我想从每行中删除前导加号/减号 git diff 。在你问我为什么要这样做的时候，请允许我概述我的理由：

1. 恰好为80个字符的行会溢出一个字符，它看起来简单尴尬


2. 着色足以区分添加/删除操作
   
3. 我更愿意保留终端窗口宽度为80个字符（而不是任意的81个字符）以保持与我在终端中执行的所有其他操作保持一致（ git 之外）

有没有这样的配置选项？如果没有，我怎么能这样做，仍然允许我通过比较小于 -style

解决方案

一个选项是使用 sed 从diff中移除不需要的字符，同时保留颜色：

  git diff --color | sed -rs / ^（[^  -  +] *）[ -  +] / \\1 /| less -r 
  

（请注意，您还需要删除前导空格，因为它是由差异。）

My question is rather simple, though I have had no luck finding an answer.

I'd like to remove the leading plus/minus symbols from each line in git diff. Before you ask why I wish to do this, allow me to outline my reasons:

1. Lines that are exactly 80 chars will overflow by a single character, which just looks plain awkward
2. The coloring is enough for me to distinguish between additions/deletions
3. I'd prefer to keep my Terminal's window width at 80 chars (as opposed to an arbitrary 81 chars) to maintain consistency with everything else I do in my Terminal (outside of git)

Is there some config option for doing this? If not, how can I do this in a way that still allows me to page through my diff less-style?

Any insight would be greatly appreciated.

解决方案

One option is to use sed to remove the undesired character from diff, while preserving the color:

git diff --color | sed -r "s/^([^-+ ]*)[-+ ]/\\1/" | less -r

(Note that you need to remove the leading space as well, as it is emitted by diff.)
