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.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 1.2.6 or later:

• https://security.snyk.io/vuln/SNYK-JS-MINIMIST-2429795 (version <=1.2.5)
• https://snyk.io/vuln/SNYK-JS-MINIMIST-559764 (version <=1.2.3)

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:

```

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.

install

npm install minimist
