use Winmerge inside of Git to file diff

Question

Is there a way to use Winmerge inside of git to do Diffs?

Answer 1

I faced trouble using the first part in 2 places and fixed it as follows

1. The second command for setting up winmerge.cmd required an extra slash on cmdline (before $LOCAL and $REMOTE), else cygwin was substituting the variable in cmdline

   C:\myGitRepo>git config --replace --global difftool.winmerge.cmd "winmerge.sh \"\$LOCAL\" \"\$REMOTE\""
   

2. changed the winmerge.sh file to (without this, was getting right-path-invalid error)

   #!/bin/sh
   echo Launching WinMergeU.exe: "$(cygpath -aw "$1")" "$(cygpath -aw "$2")"
   "$PROGRAMFILES/WinMerge/WinMergeU.exe" -e -ub -dl "Base" -dr "Mine" "$(cygpath -aw "$1")" "$(cygpath -aw "$2")"
