usage

Prompter = require('cli-prompter')

Prompter(questions, (err, values) => {})

questions is an array of objects that each describe a prompt for the user.

a question object must have a string type to determine what prompt type will handle it.

most prompt types support the following:

{
  type: String,
  name: String,
  message: String,
  default // optional
}

the callback will be called when all questions have been answered with either an error or all the answered values.

prompt types

there are a [wide variety of prompts] available thanks to @derhuerst's prompt-skeleton.

TODO

• [ ] date
• [ ] mail
• [ ] multiselect
• [ ] number
• [ ] range
• [ ] select
• [x] text
• [ ] tree-select
• [ ] switch
• [x] autocomplete
• [x] confirm (based on inquirer and using text)

here's what we have so far:

text

✔ Give your app a name (pythonomorphs-rewinders)

{
  name: String,
  message: String,
  default: String // optional
}

confirm

✔ Continue? (Y/n) … 

{
  name: String, // optional
  message: String,
  default: Boolean // optional
}

autocomplete

  suggest: ({ input, values }, cb) => cb(err, suggestions)
}

where suggestions is an array of either:

• strings
• objects with title and value keys
