Question 1

How does Notty compare to Termion for OCaml terminal programming?

Accepted Answer

Notty uses a declarative, image-based model inspired by Haskell's Vty, focusing on composable graphics, while Termion offers a more traditional, imperative approach with finer control. Notty is better for abstract, expressive designs, but Termion suits low-level terminal manipulation.

Question 2

How to handle keyboard input in Notty?

Accepted Answer

Notty provides input facilities through its Unix modules; refer to the examples in the documentation for handling events. Typically, you integrate with Lwt or Unix backends to read input and update the composable image dynamically.

Question 3

Does Notty support mouse events in terminal applications?

Accepted Answer

Notty's support for mouse events is not explicitly highlighted in the core features; you may need to rely on terminal capabilities or extend the library, as it focuses more on output and composable images.

Question 4

Can I use Notty with Async instead of Lwt for asynchronous programming?

Accepted Answer

Notty includes modules for Lwt on Unix, but using Async would require custom backend development or integration, as it's not directly supported out of the box.

Question 5

Is Notty good for building complex TUI applications like text editors?

Accepted Answer

Notty's declarative model is suitable for TUIs, but for complex applications, you'll need to implement custom widgets, as it doesn't provide a rich set of pre-built components, relying on its composable image system.

Question 6

How to install Notty with opam or dune?

Accepted Answer

Install Notty via opam with 'opam install notty', and it integrates with dune for building—check the README for examples using 'dune build @ex' to compile sample programs.
