I'm running Mercurial from the command line on Windows XP. I've got the extdiff plugin. I wanted
to use Vim's DirDiff command. I've tried putting
cmd.vimdiff = gvim opts.vimdiff = -f '+next' '+execute "DirDiff" argv(0) argv(1)'
In my Mercurial.ini. If I do hg vimdiff then gvim opens with a file name '+next'. I think the problem is to do with quoting and pathnames specific to windows. I've tried a number of permutations of backslashes and single and double quotes (not entirely randomly) but with no luck.
I've solved my problem for now by making a separate script to invoke gvim i.e.
[extdiff] cmd.vimdiff = c:\python25\python.exe opts.vimdiff = c:\test\gvimdiff.py
and gvimdiff.py being
import sys import os os.system('gvim -c "DirDiff %s %s"' % (sys.argv,sys.argv))
But if anyone knows the secret incantation to make it work direct from the command line let me know and I'll maybe try and get the documentation updated.
