Usage

Install with: npm i -P eclipt

const { eclipt } = require('eclipt');

eclipt('my-awesome-tool', {
    description: 'My Awesome Tool can do anything you with', // Optional description
    action: input => // optional action for the command
        console.log('You have run: %s with following input', input.name, input),

    // optional array of supported arguments
    // OR single string to allow any number of arguments
    args: [ 'MY_ARG_1', 'MY_ARG_2' ],
    opts: {

        // Any number of options
        foo: { flag: true }, // A boolean option
        bar: { value: 'value' }, // A regular key and the name for it's value
        baz: { multi: true, value: 'value' }, // An array option that can appear multiple times
        opt1: { value: 'value', alias: 'o' }, // Aliased option
        opt2: { description: 'Does that' } // Optional description
    },
    commands: {
        'command-name': { /* (description?, action?, args?, opts? commands?) */ }
    }
});

TODO

• unquote arguments and values
• mark multi options some way in the help
• validate against repeated aliases
