minimist

parse argument options

This module is the guts of optimist's argument parser without all the
fanciful decoration.

example

var argv = require('minimist')(process.argv.slice(2));
console.log(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' }

security

Previous versions had a prototype pollution bug that could cause privilege
escalation in some circumstances when handling untrusted user input.

Please use version 1.2.3 or later: https://snyk.io/vuln/SNYK-JS-MINIMIST-559764

methods

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:

```

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
--.

• 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.
