* Add possibility for using MxId/Token with Matrix
Makes it possible to configure a Matrix bot to use Matrix ID + Access token instead of username/password. This makes it possible to use the bot in environments where password login is disabled (for example SSO environments).
Matrix user ID's are commonly referred to as "MXID's". I thought about (ab)using "Login" here but it felt like a bad idea given it's used as "username" for the password login. None of the other configuration items felt fitting.
Closes#1429
* MxId -> MxID
* Add err != nil to matrix.NewClient
* matrix: send the display name (the nickname in matrix parlance) instead of the user name
There is also the option UseUserName (already in use by the discord bridge) to turn back to the old behavior.
* matrix: update displayNames on join events
* matrix: introduce a helper.go file to keep matrix.go size reasonable
This includes at least c-source-files, cpp-source-files,
markdown-files, Rust-files, and plaintext files.
We already allow uploading arbitrary executables. (And javascript-files,
coincidentally.) Not permitting these other text files would be highly unexpected.
When there is a valid HTML formatting then remove this in the cleartext
field of the matrix client. This leads to nicer push messages on
smartphone apps.
Fix#1188
This uses our own gomatrix lib with the SendHTML function which
adds HTML to formatted_body in matrix.
golang-commonmark is used to convert markdown into valid HTML.
Currently fully support mattermost,slack and discord.
Message deleted on the bridge or received from other bridges will be
deleted.
Partially support for Gitter.
Gitter bridge will delete messages received from other bridges.
But if you delete a message on gitter, this deletion will not be sent to
other bridges (this is a gitter API limitation, it doesn't propogate edits
or deletes via the API)
