          argparse

          Build Status NPM version

          CLI arguments parser for node.js, with sub-commands support. Port of python's argparse (version 3.9.0).

          Difference with original.

          • JS has no keyword arguments support.
            • Pass options instead: new ArgumentParser({ description: 'example', add_help: true }).
          • JS has no python's types int, float, ...
            • Use string-typed names: .add_argument('-b', { type: 'int', help: 'help' }).
          • %r format specifier uses require('util').inspect().

          More details in doc.

          Example

          test.js file:

          #!/usr/bin/env node
          'use strict';
          
          const { ArgumentParser } = require('argparse');
          const { version } = require('./package.json');
          
          const parser = new ArgumentParser({
            description: 'Argparse example'
          });
          
          parser.add_argument('-v', '--version', { action: 'version', version });
          parser.add_argument('-f', '--foo', { help: 'foo bar' });
          parser.add_argument('-b', '--bar', { help: 'bar foo' });
          parser.add_argument('--baz', { help: 'baz bar' });
          
          console.dir(parser.parse_args());
          

          Display help:

          $ ./test.js -h
          usage: test.js [-h] [-v] [-f FOO] [-b BAR] [--baz BAZ]
          
          Argparse example
          
          optional arguments:
            -h, --help         show this help message and exit
            -v, --version      show program's version number and exit
            -f FOO, --foo FOO  foo bar
            -b BAR, --bar BAR  bar foo
            --baz BAZ          baz bar
          

          Parse arguments:

          $ ./test.js -f=3 --bar=4 --baz 5
          { foo: '3', bar: '4', baz: '5' }
          

          API docs

          Since this is a port with minimal divergence, there's no separate documentation. Use original one instead, with notes about difference.
