Motive

From the Hackacamel list I picked up working on the cdf plotter using TUI. Now I have never developed TUIs or GUIs so I thought this would be the perfect thing to do.

The initial hurdle was choosing the library, I wanted to try use OCaml 5 so I chose Minttea which is TUI framework inspired by Bubble Tea implemented in Golang and uses the The elm architecture (The TEA in minttea).

Biggest Hurdles

let to_path ~env path = Eio.Stdenv.fs env / path

let _ =
  Eio_main.run (fun env ->
    let process_manager = Eio.Stdenv.process_mgr env in
    Eio.Process.parse_out process_manager Eio.Buf_read.take_all ["ls"])
