This set of shim files enables the git Tower.app application to use kdiff3 as a diff and merge tool.
Kdiff3 isn't the most "mac-like" application, but it's my favorite merge tool out there as it has full 3-way merging in a 4 pane layout.
Clone this repository and run the install script to install the plist file and shim shell script in the appropriate directory.
cd /tmp
git clone [email protected]:tednaleid/git-tower-kdiff3-shim.git
cd git-tower-kdiff3-shim
./install.sh
The shim script assumes that you've downloaded the kdiff3.app file and have it in your applications directory. If you've gotten kdiff3 through some other means (such as homebrew), you'll want to modify the script accordingly.
