@technomancy @suricrasia for the gbadev discord I run ircord (https://github.com/Yardanico/ircord) which does a bunch of things quite well:
- detects bold, italic, newline etc. and makes them look OK on irc
- detects edits and shows a diff of what changed instead of reposting the entire message
- detects long messages / code snippets and calls out to a pastebin service instead of sending a multi-line monstrosity (I had to make a fork to stop it linking to the Nim playground though, as it was made for that one community)
