Pro 3 way merge support
P4Merge presents merge information in 4 panes - BASE, LOCAL, REMOTE and MERGE_RESULT.
P4Merge is free of charge.
Pro Detects minimal changes without having a common ancestor
After a merge sometimes you have conflicts. You can resolve them by using a merge tool. You can run
git mergetool --tool-help to get more details about what tools are supported.
You will get an output like the following
git mergetool --tool=<tool> may be set to one of the following:
p4merge tortoisemerge vimdiff vimdiff2 vimdiff3
The following tools are valid, but not currently available:
araxis bc bc3 codecompare deltawalker diffmerge diffuse ecmerge emerge gvimdiff gvimdiff2 gvimdiff3 kdiff3 meld opendiff tkdiff winmerge xxdiff
Some of the tools listed above only work in a windowed environment. If run in a terminal-only session, they will fail.
Pro Cross-platform with a good Mac port
P4Merge works on Windows, Linux and OS X.
Pro Also has image diffing
For those who are working in both text based source code or files, as well as images, its nice to have the diff functionality of both present in the same product.
Con Directory comparison is not supported
With P4Merge it's impossible to compare two different directories to find differences.
