alt Hacker NewsA thing that shocked me as I was working on the text editor was how capable modern terminal emulators are when you account for ANSI extensions. First-class clipboard access, mouse events, precise text styling, focus tracking, system notifications, key press/release events, etc. are all possible with a modern terminal emulator. There's not really anything else you need to build a very competent, ergonomic editor UI.
You can even use tools like trolley to wrap the entire application up in a ghostty-powered shim that presents the application as a native UI application: https://github.com/weedonandscott/trolley
I appreciate this, but I'm not concerned with the capabilities of the terminal or the GUI. What would be unhelpful, to me, would be to build a TUI because then if I wanted to send the actual app state to - for instance, a web browser which runs the library in WASM - the only way would be to pipe the terminal output across the shared buffer, instead of just blitting the app/editor state into it (or the relevant messages, like CRDTs).
Contrast that with a library: I could capture the inputs from any source - browser, native app, network, etc - work with the data using the single library, and then render the result in whatever client (or as many clients) as I wanted.
