Hi,
I have issue with comint mode:
I reproduced the issue with simple Node.js code:
shell.js file:
#!/usr/bin/env node
const readline = require('readline');
var prompt = 'lips> ';
var continuePrompt = '... ';
const rl = readline.createInterface({
input: process.stdin,
output: process.stdout,
prompt: prompt,
terminal: !!process.stdin.isTTY
});
if (process.stdin.isTTY) {
rl.prompt();
}
rl.on('line', function(line) {
if (process.stdin.isTTY) {
rl.prompt();
}
});
If I run this as scheme in GNU Emacs:
(run-scheme "/path/.../shell.js")
;; this is needed otherwise I get duplicated input
(setq comint-process-echoes t)
And the issue I have is that when I resize the window I've got duplicated:
lips> lips> lips> lips>
What I did wrong with my REPL in Node.js anybody have idea if I need to setup
something in Emacs. REPL works fine in terminal emulator and ansi-term.
I've asked the same question on StackOverflow in hope I'll get some answers
how to fix this:

I have no idea if it's issue with Node.js Readline or with GNU Emacs comint
mode.
