git - 在 diff 中也使用逗号作为单词分隔符

Question

如何,为 git diff --word-diff 添加单词分隔符？

例如，我希望差异能够识别

function(A,B,C) -> function(A, B, C)

只添加了空格而不是替换整行。

Answer 1

使用--word-diff-regex：

   --word-diff-regex=<regex>
       Use <regex> to decide what a word is, instead of considering runs
       of non-whitespace to be a word. Also implies --word-diff unless it
       was already enabled.

       Every non-overlapping match of the <regex> is considered a word.
       Anything between these matches is considered whitespace and
       ignored(!) for the purposes of finding differences. You may want to
       append |[^[:space:]] to your regular expression to make sure that
       it matches all non-whitespace characters. A match that contains a
       newline is silently truncated(!) at the newline.

       The regex can also be set via a diff driver or configuration
       option, see gitattributes(1) or git-config(1). Giving it explicitly
       overrides any diff driver or configuration setting. Diff drivers
       override configuration settings.

我从未使用过它，但我想这git diff --word-diff-regex="[^[:space:],]+"可能会奏效。

除了 KurzedMetal 的回答：如果没有引号，它的效果会更好，因为它在点击 TAB 时不会破坏我的 bashs 自动完成。

git diff --word-diff-regex=[^[:space:],]+

您也可以尝试-w/ --ignore-all-space，尽管这可能会忽略比您喜欢的更多的空格。
