Hi, author here. I’ve written a debugger for sed in Rust. This was not only to learn rust, but to actually have a solid debugger for sed. I’ve started learning sed recently and decided to start writing various algorithms in it. And as sed doesn’t have numbers and can just filter/transform text, this is a challenge even for something like comparing two numbers. I’ve seen people do amazing things with it.

I’d be glad for any comments regarding code quality or the debugger itself.

I like the tui UI, what was it like mapping it layout in the terminal? I've always wanted to try building a CLI interface like that.

There are Rust and C++ bindings, and it performs some truly ridiculous TUI tricks.
