promisify prompt.get

[caub]

@gangstead Hi, could you check this very small PR?

It just promisifies prompt.get (if no callback passed)

it'll help for #170

We have to do

const prompt = require('prompt');

const getPrompt = require('util').promisify(prompt.get).bind(prompt);

every time we use prompt, so that PR would be cool

I'm not really active on this project any more, so I'm a little hesitant to merge the PR when the build isn't passing.

Ah, I initially put an arrow callback

/home/travis/build/flatiron/prompt/lib/prompt.js:197
  return new Promise((resolve, reject) => {
                                       ^^
SyntaxError: Unexpected token =>

then I changed it to a function for node 0.12 34658ba

The CI should pass, I just don't manage to restart the CI build

It'd be really great if you could merge it, I'm sure many other users would benefit from this promise-style prompt.get

Thanks in advance for your time

Ah, I forgot one arrow fn (there were 2, I changed only 1), thanks CI

It should pass now, sorry

The error now https://travis-ci.org/flatiron/prompt/jobs/657864911#L322 has nothing to do with this PR

@gangstead

• added a test for prompt.get() as a Promise
• updated README
• fixed npm test on recent node versions with an ugly hack (added util.print back because it was removed in recent node versions, I didn't know it existed though:)

Thanks @gangstead , do you have npm push access by any chance?

If not, https://www.npmjs.com/package/prompt shows @indexzero and @jcrugzz as collaborators, if they can do a npm publish at some point, that would be cool!

Thanks guys

[gangstead]

Nope. Sorry.

@indexzero Hey, could you please, when you've a minute, do a npm version minor, git push and a npm publish?

We added a helpful promisified prompt.get in this PR

[apolopena]

Yeah this would really be nice.

Can any one of the npm collaborators @jcrugzz @indutny @indexzero do something please? we need to sync this new updates on npm
