You can specify which lists of cards are considered done so that moving a card to a “Done” list will mark them done also in OmniFocus when syncing.
To start using it, simply install the gem and start sync:
$ gem install omnifocus-trello $ of sync
On the first run the sync will create
~/.omnifocus-trello.yml file. Follow the instructions in the file to get a Trello access token. After completing the instructions and filling the needed information, just re-run
of sync and it will do the first sync. After that you can run
of sync any time and it will update the OmniFocus data.
The code is available at GitHub.
