TortoiseHg: No visual diff tools were detected (Mac)

Question

I installed meld in my Mac and i want to use this as a visual diff tool in TortoiseHg. (Note that I am using a Mac. )

I have the following configuration in my .hgrc file. But when I double clicked on a file, I got this "No visual diff tools were detected". Am I missing something in the file ?

This is getting a little bit frustrating because I have spent hours on this and still wasn't able to get a solution. Need some help here please .

[ui]
merge = /opt/local/bin/meld

[tortoisehg]
vdiff = /opt/local/bin/meld

for anyone still passing by here, there's a typo in OP .hgrc file: it's merge, without d – Wanton

Answer 1

I had the same problem with kdiff3 on osx, but I'm sure this solution works for meld as well. What worked was to enable the extdiff extension in mercurial, then define kdiff3 as an extdiff command and use that in the [tortoisehg] section.

This is my .hgrc file with these changes made:

[extensions]
extdiff =

[extdiff]
cmd.kiddf3 = /usr/local/bin/kdiff3

[tortoisehg]
vdiff = kdiff3

I have TortoiseHg locally installed in my home directory (since Ubuntu PPA was abandoned). My .hgrc starts with following line:

%include PATH_TO_THG_REPO/contrib/mergetools.rc

This file contains description of various merge and diff tools. Without it TortoiseHg doesn't detect any.

Once path to this file changed (when I copied .hgrc to another machine) and I got the same error message.

P.S. Don't forget to replace PATH_TO_THG with your specific path.
