Filter to put OSA languages into a git-repository. So you can put your .scpt-file (AppleScript, JavaScript) into your git-repository, and get full textual diff support.
Either clone this repository, or download the latest release and unzip it to a folder where you want to install it.
Configure the filter by running the following command:
./setup.sh configure
For every reporistory you want to use it, put the line *.scpt filter=osa in the gitattributes of your repository. Do this by running the command below in the root of your repository:
echo "*.scpt filter=osa" >> .gitattributes
If you want to add your own git configuration, use the following configure command:
./setup.sh configure --no-git
To reset the configuration, run this command:
./setup.sh reset
If you have trouble with the script, switch on logging with:
./setup.sh configure --git-log
Logging can be found in ~/Library/Logs/Catsdeep/osagitfilter.log and can be easy inspected with Console.app.
Some git-clients, like GitHub Desktop, can be quite chatty so log files grow quite fast. With the following command you can create a new log file, while preserving the old ones:
./setup.sh rotate
Default, it prevents from accidently committing AppleScript files with Debugging Mode (from AppleScript Debugger) switched on. Run osagitfilter --help to see more options.
I've setup a demo repository with different .scpt-files.
If you want to (re-)apply osagitfilter to a repository (for example, if you already added your binary .scpt file to git, but want to use osagitfilter), execute the following statement:
git add --renormalize .
