So ... I recently discovered the Glicol music programming language ( glicol.org ), and thought it was pretty cool. But the existing implementation is browser-based, and I don't like doing that kind of thing in a browser, so I decided to develop a TUI environment for Glicol. I've done some GUI programm…

I don't think this is possible with the terminal. unlike GUI system, the tty doesn't actually use "modifier" keys, instead certain key combinations are encoded as ASCII control characters or ANSI escape codes, for example, Ctrl-a is sent as ASCII SOH, start of heading, or 0x01, Alt-a is usually sent…

[image] caelia: Mm, yeah ... it happens that Kitty is my usual terminal. Kitty protocol is supported by more than just Kitty: it's also supported by iTerm2, Ghostty, etc. With more on the way. But, well… it's really funny that it took 50+ years for someone to, finally, push through something…
