HexTwitch: Rust Edition 1.0.0

NOTE: This Plugin can ONLY be used with a modified version of HexChat. The Patch File is included in this Repository at ./hex.patch.

This is a Plugin for HexChat which aims to integrate some of the more advanced features of the Twitch Chat IRC bridge; Specifically, user Badges and channel events such as Subscriptions. This information is supplied via IRCv3 Tags.

There are various IRC clients built specifically for Twitch, such as Chatty, but none seem to compare to HexChat in terms of performance. This is, therefore, an attempt to rework HexChat into a Twitch chat client, without altering its behavior on other IRC Networks.

One problem, however, stands in the way: The HexChat Plugin interface does not provide Callbacks with the IRC Tags. Therefore we must modify HexChat to add this functionality, using the Patch File mentioned above (This could be submitted as a Pull Request, but currently, my C sucks and I would rather not waste their time).

Regarding the Coming Update

Twitch is deprecating several key IRC commands. They will be removed on or around 2023-02-18. This removal includes all of the most important moderation and channel editor capabilities.

As a result, this plugin may see a great decrease in utility; At the very least, all installations of current and past versions will stop working for functions such as banning users and setting a channel to slow mode. I am going to try to implement access to the main API, and hopefully keep as much of the current functionality as possible, but updating the plugin will be required.

Patching HexChat

With Git and GNU Patch installed, the following commands should download and patch the latest HexChat source code:

git clone https://github.com/hexchat/hexchat.git build/hexchat
patch -p0 -d build/hexchat -i ../../hex.patch

When the patch is applied, you can then build and install HexChat as normal from its directory at build/hexchat/.

Building the Plugin

You will need to have Cargo installed. Cargo can be installed and set up easily with RustUp. When this is done, run the following command in the Directory where you unpacked this Repository:

cargo build --release

After Cargo compiles the plugin, its Binary should be in target/release/, and should be named something like libhextwitch or libhextwitch.so. Move this File into the addons Directory in your HexChat config Directory; On Linux, this should be at $XDG_CONFIG_HOME/hexchat/addons/.

If you have not patched HexChat, it will probably crash. Otherwise, you should now have Twitch features.

Badge Icons

It is not currently feasible to embed images inline in HexChat without creating a custom font. In lieu of that potential far-future solution, and to keep installation as simple as possible, Twitch user badges are mapped to Unicode codepoints, as detailed in the following lists.

Badges without a codepoint specified will be rendered as ?. A list of all unknown badge names can be viewed with the /UNKNOWNS command. This information should be provided as an Issue in this repository, so that they can be added to the plugin.

Note that some typefaces may render some of these characters in an Emoji style, which may clash somewhat with the rest of the interface.
