    Command Line Interface Options

    Simple and small options parser for CLI applications.

    Large dependencies are a problem. Use them sparingly but whenever useful. When creating them, keep them light.

    Install

    npm install --save @pipobscure/options

    Usage

    Simple Program

    import { basename } from 'path';
    import { Program } from '@pipobscure/options';
    
    const program = new Program(basename(process.argv[1], '.js'), (opts, args)=>{
      // Do your main stuff here
    });
    program.main.flag('long', 'l', 'describe what long does', false /*default*/);
    program.main.option('something', 'describe what --somethig=<value> or --something <value> does', 'default value');
    program.run(process.argv);

    Command-Based Program

    import { basename } from 'path';
    import { Program } from '@pipobscure/options';
    
    const program = new Program(basename(process.argv[1], '.js'));
    
    const one = program.command('one', (opts, args)=>{
      // Do the stuff for command: one
    });
    one.flag('long', 'l', 'describe what long does for one', false /*default*/);
    one.option('something', 'describe what --somethig=<value> or --something <value> does in one', 'default value', (option)=>!!~[ 'opt1', 'opt2' ].indexOf(option.value)); // defaults & validation is optional
    
    const two = program.command('two', (opts, args)=>{
      // Do the stuff for command: two
    });
    two.flag('long', 'l', 'describe what long does for two', false /*default*/);
    two.option('something', 'describe what --somethig=<value> or --something <value> does in two', 'default value');
    
    program.run(process.argv);
