  "readme": "# Commander.js\n\n  The complete solution for [node.js](http://nodejs.org) command-line interfaces, inspired by Ruby's [commander](https://github.com/visionmedia/commander).\n\n [![Build Status](https://secure.travis-ci.org/visionmedia/commander.js.png)](http://travis-ci.org/visionmedia/commander.js)\n\n## Installation\n\n    $ npm install commander\n\n## Option parsing\n\n Options with commander are defined with the `.option()` method, also serving as documentation for the options. The example below parses args and options from `process.argv`, leaving remaining args as the `program.args` array which were not consumed by options.\n\n```js\n#!/usr/bin/env node\n\n/**\n * Module dependencies.\n */\n\nvar program = require('commander');\n\nprogram\n  .version('0.0.1')\n  .option('-p, --peppers', 'Add peppers')\n  .option('-P, --pineapple', 'Add pineapple')\n  .option('-b, --bbq', 'Add bbq sauce')\n  .option('-c, --cheese [type]', 'Add the specified type of cheese [marble]', 'marble')\n  .parse(process.argv);\n\nconsole.log('you ordered a pizza with:');\nif (program.peppers) console.log('  - peppers');\nif (program.pineapple) console.log('  - pineappe');\nif (program.bbq) console.log('  - bbq');\nconsole.log('  - %s cheese', program.cheese);\n```\n\n Short flags may be passed as a single arg, for example `-abc` is equivalent to `-a -b -c`. Multi-word options such as \"--template-engine\" are camel-cased, becoming `program.templateEngine` etc.\n\n## Automated --help\n\n The help information is auto-generated based on the information commander already knows about your program, so the following `--help` info is for free:\n\n```  \n $ ./examples/pizza --help\n\n   Usage: pizza [options]\n\n   Options:\n\n     -V, --version        output the version number\n     -p, --peppers        Add peppers\n     -P, --pineapple      Add pineappe\n     -b, --bbq            Add bbq sauce\n     -c, --cheese <type>  Add the specified type of cheese [marble]\n     -h, --help           output usage information\n\n```\n\n## Coercion\n\n```js\nfunction range(val) {\n  return val.split('..').map(Number);\n}\n\nfunction list(val) {\n  return val.split(',');\n}\n\nprogram\n  .version('0.0.1')\n  .usage('[options] <file ...>')\n  .option('-i, --integer <n>', 'An integer argument', parseInt)\n  .option('-f, --float <n>', 'A float argument', parseFloat)\n  .option('-r, --range <a>..<b>', 'A range', range)\n  .option('-l, --list <items>', 'A list', list)\n  .option('-o, --optional [value]', 'An optional value')\n  .parse(process.argv);\n\nconsole.log(' int: %j', program.integer);\nconsole.log(' float: %j', program.float);\nconsole.log(' optional: %j', program.optional);\nprogram.range = program.range || [];\nconsole.log(' range: %j..%j', program.range[0], program.range[1]);\nconsole.log(' list: %j', program.list);\nconsole.log(' args: %j', program.args);\n```\n\n## Custom help\n\n You can display arbitrary `-h, --help` information\n by listening for \"--help\". Commander will automatically\n exit once you are done so that the remainder of your program\n does not execute causing undesired behaviours, for example\n in the following executable \"stuff\" will not output when\n `--help` is used.\n\n```js\n#!/usr/bin/env node\n\n/**\n * Module dependencies.\n */\n\nvar program = require('../');\n\nfunction list(val) {\n  return val.split(',').map(Number);\n}\n\nprogram\n  .version('0.0.1')\n  .option('-f, --foo', 'enable some foo')\n  .option('-b, --bar', 'enable some bar')\n  .option('-B, --baz', 'enable some baz');\n\n// must be before .parse() since\n// node's emit() is immediate\n\nprogram.on('--help', function(){\n  console.log('  Examples:');\n  console.log('');\n  console.log('    $ custom-help --help');\n  console.log('    $ custom-help -h');\n  console.log('');\n});\n\nprogram.parse(process.argv);\n\nconsole.log('stuff');\n```\n\nyielding the following help output:\n\n```\n\nUsage: custom-help [options]\n\nOptions:\n\n  -h, --help     output usage information\n  -V, --version  output the version number\n  -f, --foo      enable some foo\n  -b, --bar      enable some bar\n  -B, --baz      enable some baz\n\nExamples:\n\n  $ custom-help --help\n  $ custom-help -h\n\n```\n\n## .prompt(msg, fn)\n\n Single-line prompt:\n\n```js\nprogram.prompt('name: ', function(name){\n  console.log('hi %s', name);\n});\n```\n\n Multi-line prompt:\n\n```js\nprogram.prompt('description:', function(name){\n  console.log('hi %s', name);\n});\n```\n\n Coercion:\n\n```js\nprogram.prompt('Age: ', Number, function(age){\n  console.log('age: %j', age);\n});\n```\n\n```js\nprogram.prompt('Birthdate: ', Date, function(date){\n  console.log('date: %s', date);\n});\n```\n\n## .password(msg[, mask], fn)\n\nPrompt for password without echoing:\n\n```js\nprogram.password('Password: ', function(pass){\n  console.log('got \"%s\"', pass);\n  process.stdin.destroy();\n});\n```\n\nPrompt for password with mask char \"*\":\n\n```js\nprogram.password('Password: ', '*', function(pass){\n  console.log('got \"%s\"', pass);\n  process.stdin.destroy();\n});\n```\n\n## .confirm(msg, fn)\n\n Confirm with the given `msg`:\n\n```js\nprogram.confirm('continue? ', function(ok){\n  console.log(' got %j', ok);\n});\n```\n\n## .choose(list, fn)\n\n Let the user choose from a `list`:\n\n```js\nvar list = ['tobi', 'loki', 'jane', 'manny', 'luna'];\n\nconsole.log('Choose the coolest pet:');\nprogram.choose(list, function(i){\n  console.log('you chose %d \"%s\"', i, list[i]);\n});\n```\n\n## Links\n\n - [API documentation](http://visionmedia.github.com/commander.js/)\n - [ascii tables](https://github.com/LearnBoost/cli-table)\n - [progress bars](https://github.com/visionmedia/node-progress)\n - [more progress bars](https://github.com/substack/node-multimeter)\n - [examples](https://github.com/visionmedia/commander.js/tree/master/examples)\n\n## License \n\n(The MIT License)\n\nCopyright (c) 2011 TJ Holowaychuk &lt;tj@vision-media.ca&gt;\n\nPermission is hereby granted, free of charge, to any person obtaining\na copy of this software and associated documentation files (the\n'Software'), to deal in the Software without restriction, including\nwithout limitation the rights to use, copy, modify, merge, publish,\ndistribute, sublicense, and/or sell copies of the Software, and to\npermit persons to whom the Software is furnished to do so, subject to\nthe following conditions:\n\nThe above copyright notice and this permission notice shall be\nincluded in all copies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED 'AS IS', WITHOUT WARRANTY OF ANY KIND,\nEXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF\nMERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.\nIN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY\nCLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT,\nTORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE\nSOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.",
