Suppress needless dialogs from kdiff3?

Question

I use kdiff3 on Windows as the visual merge tool for TortoiseHG / Mercurial.

Often when doing a merge or rebase it will show a dialog like this:

Another variation is that the two files being merged were "binary equal".

Since these messages are basically saying that there is no conflicts / nothing to do, I'd like to suppress them - is that possible?

I don't see anything pertinent in the kdiff3 command line options.

Answer 1

Although having a bit misleading name, --auto option does what you want.

From the documentation:

--auto No GUI if all conflicts are auto-solvable. (Needs -o file)

This help text can also be accessing from the command line with kdiff3 --help.
