问题
Is there a way to remove version number change noise from a Git diff like this one? Specifically if a line only contains changes from one number to another can I set up Git diff to ignore it?
回答1:
I think this can be achieved using git-diff --word-diff-regex=[^0-9] (see [^0-9] in action). For a more complex pattern you'll need a more complex regex but, except recursion, everything is possible with regex.
From Git - git-diff --word-diff-regex documentation
--word-diff-regex=
Use < regex > to decide what a word is, instead of considering runs of non-whitespace to be a word. Also implies
--word-diffunless 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.For example,
--word-diff-regex=.will treat each character as a word and, correspondingly, show differences character by character.The regex can also be set via a diff driver or configuration option, see gitattributes[5] or git-config[1]. Giving it explicitly overrides any diff driver or configuration setting. Diff drivers override configuration settings.
