Running Emacs Functions in Batch Mode

Originally posted at [2011-11-10 Thu 10:22]

I use emacs for a lot of things at work. One of the more useful is org-mode for to do lists, scheduling and meeting notes. Org-mode can sync to mobile devices running the app MobileOrg. Unfortunately, that sync is a manual process. The good news, emacs is scriptable and can be run in batch mode to automate things. Here are a couple of things I use.

Note: Emacs batch mode spews a huge amount of crap to stderr. If you’re putting these in cron, you may want to slap a 2>/dev/null on there to keep it quiet.

1 Sync with MobileOrg

The first line pushes the local org files to sync and the second pulls changes coming from the device.

emacs --batch -l $HOME/.emacs -f org-mobile-push
emacs --batch -l $HOME/.emacs -f org-mobile-pull

2 Publish Meeting Minutes

I keep meeting minutes using org-mode and then publish them to my web site. I also maintain my personal work site using org-mode. To publish all configured sites, you can use the script below.

emacs --batch -l $HOME/.emacs -f org-publish-all

If you want to publish a specific site rather than all of them, you can use this incantation.

emacs --batch -l $HOME/.emacs --eval '(org-publish "meetings")'

Updated [2012-03-22 Thu 22:49]: It’s also possible to use –eval with emacsclient. You, of course, need emacs server running but it makes those batch runs much faster.
