First, Download and install the newest version of Meld for Windows. https://download.gnome.org/binaries/win32/meld/
Next we need to edit your .gitconfig file. This file lives as a hidden file in your user directory. Here is a sample of mine:
[user]
email = [email protected]
name = Sir Kuttin
[merge]
tool = meld
[diff]
tool = meld
[mergetool "meld"]
path = C:\\Program Files (x86)\\Meld\\Meld.exe
cmd = \"C:/Program Files (x86)/Meld/Meld.exe\" --diff \"$BASE\" \"$LOCAL\" \"$REMOTE\" --output \"$MERGED\"
Once this is done, you can go to Gitkraken's Preferences and set up the merge and diff tool to use the GitConfig Default. This also allows meld to be used for git command line and should also work with other Git GUIs.
Excellent! Worked perfectly, thanks!!
