Redsync

Sync your Redmine’s wiki contents to your local filesystem.
Edit them while offline, then upsync them to Redmine.
(Requires Ruby 2.0)

gem install redsync

Usage: redsync [options]
    -v, --verbose                    Output verbose logs
    -c, --config FILE                Use specified config file instead of ~/redsync.yml
    -s, --status                     Status check. No uploads or downloads will happen
    -i, --interactive                Interactive mode (pry)

Uses Redmine’s REST API.

This software has NOT BEEN TESTED :(
Use it at your own risk.
Please beware that it may not work on all versions of Redmine (it’s working fine with my installation of 2.5-stable)

Redsync does not deal with conflicts well.
In fact, it does not deal with conflics AT ALL.
A default run of redsync will downsync first, overwriting any local changes if pages are updated on Redmine.
Then it will upsync any remaining changes.
