Re: [Kdiff3-user] [arey] dir merge - overwrite new with old

[Joachim E. <joa...@gm...>]

Hi David,

The best trick is to modify directorymergewindow.cpp, line 1409 from 
originally:
               if ( mfi.m_ageA == eNew )
to
               if ( mfi.m_ageA != eNew )

Then recompile. This just inverts the behaviour for choosing the proposed 
merge operation, but otherwise you still choose "Copy newer instead of 
merging".

Implementing this as a feature wouldn't be much work, but currently I have no 
time to make a new release.

Cheers,
Joachim
