I'm using diffmerge as my favourite tool on both Windows and Mac OS X platforms. On Windows it works fine, but on my Mac OS X the Diffmerge opens but doesn't load any files - the window is clean. I'm currently using Kdiff3, which just works fine, but I would prefer Diffmerge.
TortoiseHg version: version 2.8.2+1-54b677d8da4f Diffmerge version: 3.3.2 (I tried 4.0.0, but it didn't help this issue)
in my .hgrc:
[extdiff] cmd.kdiff3 = /Applications/kdiff3.app/Contents/MacOS/kdiff3 cmd.diffmerge = /usr/bin/diffmerge [ui] merge = kdiff3 [merge-tools] kdiff3.args = $base $local $other -o $output diffmerge.executable = /usr/bin/diffmerge diffmerge.args = -merge -result=$output -t1="Local Version" -t2=$output -t3="Other Version" -caption=$output $local $base $other diffmerge.binary = False diffmerge.symlinks = False diffmerge.gui = True
