Using diff.word-diff config option (4.7+)
Since Mercurial 4.7 word diff is in core. To enable it, put this in your ~/.hgrc:
[diff] word-diff = true
It's also enabled by ui.tweakdefaults.
To configure word diff colors/styles:
[colors] diff.deleted.changed = ... diff.deleted.unchanged = ... diff.inserted.changed = ... diff.inserted.unchanged = ...
Default colors are defined in mercurial/color.py
Using extdiff extension
Making a word difference using the ExtdiffExtension and GNU wdiff, somehow what git diff --color-words does.
Download cwdiff, a shell script, which wraps wdiff to support directories and colorizes the output.
Enable ExtdiffExtension (in ~/.hgrc):
[extensions] extdiff =
- Add wdiff command (in ~/.hgrc):
[extdiff] # if cwdiff is in your path, otherwise set to wherever you've installed cwdiff cmd.wdiff = cwdiff #add --no-color below, if you dislike colors! opts.wdiff = --diff --ab
$ hg wdiff
