[Request] Multiple lines text input

[alexgleason]

Is your feature request related to a problem? Please describe.

I'm developing an AI chat application in the terminal.

At first I just used readlines, but I needed to use clack for other parts of the TUI (configuration, prompts to the user, etc), so I ended up using clack in the chat interface too for consistency. But then later I realized I cannot insert multiple lines of text in here:

Describe the solution you'd like

Maybe a separate multiline component, or allow text to accept multiple lines with an option.

For inserting newlines, Shift+Enter would be the best, but I know it's hard to capture the Shift key. Ctrl+J to insert a newline would also be acceptable.

Most of all, I would like the ability to paste text into the terminal without the newline itself (\n) triggering the end of input. I want the Enter key to submit the text.

Describe alternatives you've considered

Using readlines directly for the chat flow of the TUI, using it to simulate the appearance of clack (this is probably what I'll do).

Some options for mutliline terminal UX:

• Control sequence (Ctrl+J or other)
• Final line containing a dot itself (or other special sequence like 3x newline)
• Opening default editor ($EDITOR) for better mutlineline editing

This is part of the roadmap, we should be able to cook something in the upcoming days 😁
