如何可视化统一差异文件中的每个字符差异？ [英] How can I visualize per-character differences in a unified diff file?
问题描述
假设我使用 git format-patch 创建了一个补丁。该文件基本上是一些元数据的统一差异。如果我在Vim中打开文件，我可以看到哪些行已被修改，但是我看不到变化行中的哪些字符不同。有没有人知道一种方法（在Vim或其他一些在Ubuntu上运行的免费软件）来显示每个字符的差异？
Say I get a patch created with git format-patch. The file is basically a unified diff with some metadata. If I open the file in Vim, I can see which lines have been modified, but I cannot see which characters in the changed lines differ. Does anyone know a way (in Vim, or some other free software that runs on Ubuntu) to visualize per-character differences?
每个字符差异的反例可视化是当执行 vimdiff ab 。
A counter example where per-character diff is visualized is when executing vimdiff a b.

diffpatch is helpful for the scenario where you're working with a single file.

查看 diff-highlight in git 2.9 。这个脚本确实是我最初寻找的东西。

推荐答案
鉴于您在问题中引用了Vim ，我不确定这是否是你想要的答案:)但Emacs可以做到这一点。打开包含diff的文件，确保你在 diff-mode 中（如果文件名为 foo.diff 或 foo.patch 会自动发生，否则请键入 Mx diff-mode < kbd> RET ），转到您感兴趣的人群，并为 refine-hunk 点击 Cc Cb 。或者使用 M-n 逐个浏览文件;这将自动完成。
Given your references to Vim in the question, I'm not sure if this is the answer you want :) but Emacs can do this. Open the file containing the diff, make sure that you're in diff-mode (if the file is named foo.diff or foo.patch this happens automatically; otherwise type M-x diff-mode RET), go to the hunk you are interested in and hit C-c C-b for refine-hunk. Or step through the file one hunk at a time with M-n; that will do the refining automatically.
