First off, terminals are messy. A small set of features is standard, but beyond that, almost every terminal has its own implementation.
I mostly test VTE-based terminals (Gnome & Xfce), with the occasional Konsole and xterm checks.
### Output
* **Colors**: the basic 8-colors palette should be broadly supported. User-defined colors is not supported in the raw linux TTY, but should work in most terminals, although it's still kinda experimental.
@ -73,7 +71,7 @@ Also, Cursive currently expects every codepoint to be a one-column character, so
* Keep in mind that if the terminal has shortcuts registered, they probably won't be transmitted to the app.
* UTF-8 input should work fine in a unicode-enabled terminal emulator, but raw linux TTY may be more capricious.

You want to help? Great! Here is a non-exhaustive list of things you could do:
* Provide example use-case: a good idea of application for existing or new components.
* Check compatibility: run the `key_codes` example on your favorite terminal, and report the results!
* Test and reports issues: a bug won't get fixed if we don't know it's there.
* Hack the code! If you feel confident with rust, pick an issue you like and hack away!
