Is possible to change the default diff tool in Mercurial?


Every time I do an hg diff file.ext I end up using a console diff application. I would like to use Kdiff3 or WinMerge (I'm using Windows).

Is there a way to change that? I can't find a reference in Mercurial documentation (I'm not talking about merge!).


Solution

  • I've solved this using a Mercurial built-in extension... I just have to add the following lines to Mercurial.ini (on Mercurial folder):

    [extensions]
    hgext.extdiff=
    
    [extdiff]
    cmd.vdiff = kdiff3
    

    When I want to use kdiff3 instead of diff I only have to use:

    hg vdiff file.ext
