I miss the simpler days of cron, but when in Rome or on OS X...

The following is ~/Library/LaunchAgents/com.kenmankoff.orggit.plist

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>Label</key>
	<string>com.kenmankoff.orggit</string>
	<key>ProgramArguments</key>
	<array>
		<string>/Users/mankoff/bin/orggitcommit.sh</string>
	</array>
	<key>RunAtLoad</key>
	<true/>
	<key>StartInterval</key>
	<integer>86400</integer>
</dict>
</plist>

Which runs the following shell script:

#!/usr/bin/env bash
cd ~/Documents/Org/
/usr/local/bin/git commit -a -m "`/bin/date +%Y-%m-%d\ %T`"

Run the following 1x:

cd ~/Library/LaunchAgents/
launchctl load com.kenmankoff.orggit

Then in my Org folder, =git lg= (aliased to git log --graph --pretty=format:'%C(red)%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%ad)' --abbrev-commit --date=short) shows:

* 926cfa9 - 2015-12-30 12:51:55 (2015-12-30)

So you can see things get checked in to git about once every few days, unless my laptop is closed a lot like it just was over the holidays. If you wanted more frequent commits, LaunchAgents can run every time a file in a folder is saved. If that is too often, a middle ground could be to run the bash script every time a file is saved, but have that script only do the commit if it has been >12 or >24 hours, using the "find -newer" command, for example. Or only if >n lines have changed (from git diff).
