API

argi.options(name, description[, options])

aliases

boolean

Type: boolean Default: false

Specifies whether the option is a boolean(true/false) or a string. If set to true arguments after the option will count as a command or as a separate option.

const parsed = argi.parse(['--boolean', 'value'])
parsed.boolean // => true
parsed._ // => ['value']

...

argi.help()

argi.parse(argv)

argv

Example:

...

const parsed = argi.parse(['--test', '--opt', 'yes', 'build']);
// => {

// =>   build: true
// => }
