Mercurial
Mercurial supports external diff
tools with the
Extdiff extension. Enable it by adding an entry to extensions
in
your .hgrc
.
[extensions]
extdiff =
You can then run hg extdiff -p difft
(assumes the difft
binary is
on your $PATH
).
You can also define an alias to run difftastic with hg. Add the
following to your .hgrc
to run difftastic with hg dft
.
[extdiff]
cmd.dft = difft
opts.dft = --missing-as-empty
hg log -p
Mercurial does not have a way of changing the default diff tool, at least to the author's knowledge.
If you just want to view the diff of the most recent commit, you can use the following.
GIT_PAGER_IN_USE=1 hg dft -r .^ -r . | less
This is equivalent to hg log -l 1 -p
, although it does not show the
commit message.
