How to use WinMerge in P4V as Merge tool (not Diff)?

[thomas-seiler-bl]

Hi,
how is the syntax when using WinMerge as 3-way merge tool in P4V? I have the arguments %b %1 %2 and %r but not sure in which order I should use them and if additional ones are recommended.

WinMerge is not better than p4merge for 3-way merge, so I would recommend using p4merge, but if you do use WinMerge, the command line would look like this (I have never used Perforce, so I have not tried the following command line to see if it works correctly)

• When merging on the middle pane

"C:\Program Files\WinMerge\WinMergeU.exe" /e /am /ub /fm /wl /wr %1 %b %2 /o %r

• When merging on the right pane

"C:\Program Files\WinMerge\WinMergeU.exe" /e /ar /ub /fr /wl /wm %b %1 %2 /o %r

See below for command line options:
