This is a Matrix bridge for Mattermost.
It's based on mattermost-client, a Node.js client that uses the official Mattermost v4 API.
- login to your Mattermost account
 - send text messages to channel you subscribed to (group, public, direct)
 - user sync
 - channel sync
 - receive text messages
 - receive typing events
 - send files
 - receive files
 - support default emojis of mattermost (translating to unicode)
 
So the basic functionality should work but there is a lot of stuff like attachments, edits, quoting, events (user x joined, user y left) that may be added in the future.
- Node.js installed on the system that runs the bridge.
 - An existing account on a Mattermost server.
 
clone this repo
cd into the directory
run npm install
Copy config.sample.json to config.json and update it to match your setup
Generate an mattermost-registration.yaml file with node index.js -r -u "http://your-bridge-server:8090"
Note: The 'registration' setting in the config.json needs to set to the path of this file. By default, it already is.
Copy this mattermost-registration.yaml file to your home server, then edit it, setting its url to point to your bridge server. e.g. url: 'http://your-bridge-server.example.org:8090'
Edit your homeserver.yaml file and update the app_service_config_files with the path to the imessage-registration.yaml file.
Restart your HS.
Launch the bridge with start.sh or node index.js. If you want to run the bridge as a service you can use the matrix-puppet-signal.service file as a template for every systemd based operating system.
