co-prompt's Issues

doesn't work on os 10.9

10.9.1
node 0.11.9

var co = require('co');

var prompt = require('co-prompt');
var password = prompt.password;
var confirm = prompt.confirm;

co(function *(){
  var ok = yield confirm('are you sure? ');
  console.log('answer: %s', ok);
  process.stdin.pause();
});

Doesn't do anything when run with node --harmony-generators untitled.js. Just quits.

For node 0.10.21, errors with unexpected token *.

Password masker inserts mask characters for backspace

If you open a password prompt and press the backspace key, the masker will insert a character, rather than erasing one.

Default option for prompt

Would be useful to have a default value for prompt.

Sending CTRL+C during a password prompt dumps unmasked pw to stdout

co-prompt/index.js

Line 86 in 81125f8

console.log('%s', buf);

Why?

Re-add "Choice" prompt.

The "choice" prompt was removed from commander.js as part of:

tj/commander.js@bf5e1f5

However, this style of prompt doesn't seem to exist in co-prompt.

Is there a plan to add this back in to co-prompt?

My Node.js process doesn't terminate when using prompt function

I suspect that the problem is that process.stdin is still referenced. See this SO answer.

I have tried another approach using readline:

const readline = require('readline');

function prompt(msg){
  return new Promise((resolve, reject) => {
    const rl = readline.createInterface({
      input: process.stdin,
      output: process.stdout
    });

    rl.question(msg, (answer) => {
      rl.close();
      resolve(answer);
    });
  });
}

What do you think?

Restricting possible user inputs

This isn't really an issue, just a question?

This is how i currently restrict the possible inputs

let a = (yield prompt("Create app? (Y/n) ")) || "Y";
while (!(/^([yn]|(yes)|(no))$/ig.test(a))) a= yield prompt("Create app? (Y/n) ");

Is there a better way of doing it?

prompt Unexpected identifier

i require the co-prompt, but throw an error that say " SyntaxError: Unexpected identifier"
var prompt1 = require("co-prompt");
var name = yield prompt1('username: ');

the error point to second prompt1

i have no idea to resovle it, could you give me the answer?

prompt.password is not working on windows

I tried to get password from gitbash then it showing error

Unhandled Rejection at: Promise {
<rejected> TypeError: process.stdin.setRawMode is not a functions
at ..\node_modules\co-promt\index.js:71:19

after commenting this, passoword take every key as a input.
I will try to solve this weekend, Small help will be appreciated.

prompt in an array

I want to loop through an array and create a series of prompts based off of this array.
I seem to be having trouble stopping the loop in order to collect each prompt sequentially.
For Example, if I have an array named DefaultArray, I want to create a prompt for each item in the DefaultArray:

var co = require('co');
var forEach = require('co-foreach');
var prompt = require('co-prompt');

forEach(defaultVars, function * (item, idx) {
    // do something awesome with generators
    var value = yield prompt(item + ': ');
    console.log(value);
}).then(handleFinish);

Suppose DefaultArray = ['Do you like Apples?', 'Do you like Oranges?'];

I would expect to see:
Do you like Apples?: yes
yes
Do you like Oranges?: no
no

Instead I see:
Do you like Apples?:Do you like Oranges?: yes
yes
yes
