    prompter

    Create json files, prompting for input and evaluating expressions.

    build status

    example

    First create a json file with embedded expressions:

    {
      "a": 1 + 2,
      "b": prompt('To be or not to be?', '!2b'),
      "c": {
        "x": prompt(),
        "y": tmpdir + "/y/file.txt"
      }
    }

    Now run the json file with the command-line tool (or write a script) to generate a valid json file, prompting from the user as necessary:

    $ prompter --tmpdir=/tmp simple.json > output.json
    To be or not to be?: (!2b) 
    c.x: 55
    $ cat output.json
    {
      "a": 3,
      "b": "!2b",
      "c": {
        "x": "55",
        "y": "/tmp/y/file.txt"
      }
    }
    

    json methods

    prompt(text, value, cb)

    Like window.prompt(), prompt the user with text and an optional default value. If text isn't provided, the long key path from the root of the json document is used.

    If cb is specified, use the return value of cb(s) for the string s obtained from the user.

    readline(cb)

    Fetch a line from the input stream, including a trailing newline.

    functions

    Every value that resolves to a function in the final output will be executed with a callback function: fn(cb). Inside the function fn, cb(err, value) should be called to give the new value or abort the transaction.

    api methods

    var prompter = require('prompter')

    prompter(src, context={}, cb)

    Evaluate the string source src under some optional context, calling cb(err, output) with the completed file contents.

    Control the delimiter by passing in a value for context.delim, which defaults to ': '.

    Returns a readable/writable stream that should be pipe into and out of a user's stdin/stdout.
