Add support for multiline input

[brianweil]

I would like to add support for multiple lines of text in the input type. I use the prompt for commit messages and sometimes one line is not enough. The UI could be as simple as pressing shift+enter to move to the next line of input. Feedback from the contributors is welcome and appreciated.

I wonder if we could call the system editor like when you git commit and get the content back afterward.

+1. karma init does this reasonably well

[jameswomack]

This would be great for doing things like blog posts from the command-line. Hexo would do well to integrate this.

Just to make sure this stays on the radar: +1

+1 Any updates on this? I support the Shift+Enter idea, either as a default to insert newline on any option, or swapped for Enter behavior which instead inserts newline on options explicitly configured as multiline.

@adjohnson916 PR welcomed.

This is now shipped with v1.1.0

I know there is editor support, but is there any chance that you will also support multiline?
I prefer would prefer multiline over editor for my application.

Multiline should allow the user to enter multiple lines, and close when it encounters an empty line (or line with only a dot) or when the user presses CTRL+D.
At least that is the standard behaviour across various command line applications I use.

I tried to look at your code to implement it myself, but I don't really understand how to implement a custom prompt... Is there any documentation or tutorial?

A working (yet untested) implementation: aleclarson/inquirer@16ddf2f

It adds a multiline boolean option to input prompts. It probably won't merge cleanly into master, because I've made other changes. But you can take inspiration from it.

The ctrl+d key binding has its own commit: aleclarson/inquirer@e5c844e

[KoStard]

Has this feature been merged? I don't see how to receive multi-line input from the user from terminal without opening external windows.

import { input } from '@inquirer/prompts';

const answer = await input({
  message: 'Enter a description',
  multiline: true,
});
console.log(answer);

I tried this, but it only accepted one line. Also I don't see anything about multiline support in the homepage: https://github.com/SBoudrias/Inquirer.js

I think this issue can be reopened to track the interest in this request.

Hi @KoStard, the multi-line comes through the editor prompt. There's been some more recent talk over here too #1583 (I'm open to improving this, but transparently, it's not on my todo list ATM. So it's up for the taking.)
