I've been trying to integrate a line editor in an async ratatui app but didn't succeed yet.
In particular, I tried to integrated reedline (as well as rustyline) in one of the ratatui async templates (simple and components templates) but I ran into different rendering and event handling problems depending on where I put the prompt.
Has anybody already tried this? I would appreciate any help or advice.
You shouldn't be doing this. Readline libraries and TUI frameworks both want to control the screen (including cursor position, clearing, etc.), so they naturally conflict.
If you want a text input area, you'll need to find a corresponding Ratatui widget, or write one yourself.
