# minimist
|
|
|
|
parse argument options
|
|
|
|
This module is the guts of optimist's argument parser without all the
|
|
fanciful decoration.

# example
|
|
|
|
``` js
|
|
var argv = require('minimist')(process.argv.slice(2));
|
|
console.dir(argv);
|
|
```
|
|
|
|
```
|
|
$ node example/parse.js -a beep -b boop
|
|
{ _: [], a: 'beep', b: 'boop' }
|
|
```
|
|
|
|
```
|
|
$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
|
|
{ _: [ 'foo', 'bar', 'baz' ],
|
|
x: 3,
|
|
y: 4,
|
|
n: 5,
|
|
a: true,
|
|
b: true,
|
|
c: true,
|
|
beep: 'boop' }
|
|
```

# methods
|
|
|
|
``` js
|
|
var parseArgs = require('minimist')
|
|
```
|
|
|
|
## var argv = parseArgs(args, opts={})
|
|
|
|
Return an argument object `argv` populated with the array arguments from `args`.
|
|
|
|
`argv._` contains all the arguments that didn't have an option associated with
|
|
them.
|
|
|
|
Numeric-looking arguments will be returned as numbers unless `opts.string` or
|
|
`opts.boolean` is set for that argument name.
|
|
|
|
Any arguments after `'--'` will not be parsed and will end up in `argv._`.
|
|
|
|
options can be:
|
|
|
|
* `opts.string` - a string or array of strings argument names to always treat as
|
|
strings
|
|
* `opts.boolean` - a boolean, string or array of strings to always treat as
|
|
booleans. if `true` will treat all double hyphenated arguments without equal signs
|
|
as boolean (e.g. affects `--foo`, not `-f` or `--foo=bar`)
|
|
* `opts.alias` - an object mapping string names to strings or arrays of string
|
|
argument names to use as aliases
|
|
* `opts.default` - an object mapping string argument names to default values
|
|
* `opts.stopEarly` - when true, populate `argv._` with everything after the
|
|
first non-option
|
|
* `opts['--']` - when true, populate `argv._` with everything before the `--`
|
|
and `argv['--']` with everything after the `--`. Here's an example:
|
|
* `opts.unknown` - a function which is invoked with a command line parameter not
|
|
defined in the `opts` configuration object. If the function returns `false`, the
|
|
unknown option is not added to `argv`.
|
|
|
|
```
|
|
> require('./')('one two three -- four five --six'.split(' '), { '--': true })
|
|
{ _: [ 'one', 'two', 'three' ],
|
|
'--': [ 'four', 'five', '--six' ] }
|
|
```
|
|
|
|
Note that with `opts['--']` set, parsing for arguments still stops after the
|
|
`--`.
