unparse-args

unparse-args
=================


A Node module to help you unparse parsed arguments back to the original argv array or a command string.

This module will:
- unparse parsed arguments back to an argv array
- easily regenerate a command string based on the unparsed array
- work with yargs, minimist, and subarg (also handles subcontexts)

Use Scenario

Imagine a hypothetical command string with flags, subcommands, options... etc:

``bash
node example.js another --number 297261 -t something -x 'something longer than just 1 word' -a -e
`

Popular argument parsing modules for Node: yargs, subarg, and minimist all parse these into an object like:

`javascript
var args = {
_: [ 'node', '/Users/arjun/example/example.js', 'another' ],
number: 297261,
t: 'something',
x: 'something longer than just 1 word',
a: true,
e: true
};
`

But we might want to manipulate it and flatten it out again to be like:
`javascript
['node', '/Users/arjun/example/example.js', 'another', '--number', '297261', '-t', 'something', '-x', 'something longer than just 1 word', '-a', '-e']
`

Installation


`bash
npm install --save unparse-args
`

Basic Usage

$3

`javascript
var unparse = require('unparse-args');
`

Assume some parsed arguments.
`javascript
var parsed = subarg(process.argv);
// OR
var parsed = minimist(process.argv);
// OR
var parsed = yargs.parse(process.argv);
`

$3

Easily unparse them into an array.
`javascript
var unparsed = unparse(parsed)
console.log(unparsed); // ['node', 'example.js', 'another', '--number', '297261', '-t', 'something', '-x', 'something longer than just 1 word', '-a', '-e']
`

$3

`javascript
var command_string = unparsed.command_string;
console.log(command_string); // node example.js another --number 297261 -t something -x 'something longer than just 1 word' -a -e
`

I know I know, unparsed is an array`, so how can it have a property?? Magic.
