The complete solution for [node.js](http://nodejs.org) command-line interfaces, inspired by Ruby's [commander](https://github.com/tj/commander).
[API documentation](http://tj.github.com/commander.js/)
## Installation
$ npm install commander --save
## Option parsing
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.
```js
#!/usr/bin/env node
/**
* Module dependencies.
*/
var program = require('commander');
program
.version('0.1.0')
.option('-p, --peppers', 'Add peppers')
.option('-P, --pineapple', 'Add pineapple')
.option('-b, --bbq-sauce', 'Add bbq sauce')
.option('-c, --cheese [type]', 'Add the specified type of cheese [marble]', 'marble')
.parse(process.argv);
console.log('you ordered a pizza with:');
if (program.peppers) console.log(' - peppers');
if (program.pineapple) console.log(' - pineapple');
if (program.bbqSauce) console.log(' - bbq');
console.log(' - %s cheese', program.cheese);
```
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.
## Coercion
```js
function range(val) {
return val.split('..').map(Number);
}
function list(val) {
return val.split(',');
}
function collect(val, memo) {
memo.push(val);
return memo;
}
function increaseVerbosity(v, total) {
return total + 1;
}
program
.version('0.1.0')
.usage('[options] <file ...>')
.option('-i, --integer <n>', 'An integer argument', parseInt)
.option('-f, --float <n>', 'A float argument', parseFloat)
.option('-r, --range <a>..<b>', 'A range', range)
.option('-l, --list <items>', 'A list', list)
.option('-o, --optional [value]', 'An optional value')
.option('-c, --collect [value]', 'A repeatable value', collect, [])
.option('-v, --verbose', 'A value that can be increased', increaseVerbosity, 0)
.parse(process.argv);
console.log(' int: %j', program.integer);
console.log(' float: %j', program.float);
console.log(' optional: %j', program.optional);
program.range = program.range || [];
console.log(' range: %j..%j', program.range[0], program.range[1]);
console.log(' list: %j', program.list);
console.log(' collect: %j', program.collect);
console.log(' verbosity: %j', program.verbose);
console.log(' args: %j', program.args);
```
## Regular Expression
```js
program
.version('0.1.0')
.option('-s --size <size>', 'Pizza size', /^(large|medium|small)$/i, 'medium')
.option('-d --drink [drink]', 'Drink', /^(coke|pepsi|izze)$/i)
.parse(process.argv);
console.log(' size: %j', program.size);
console.log(' drink: %j', program.drink);
```
## Variadic arguments
The last argument of a command can be variadic, and only the last argument. To make an argument variadic you have to
append `...` to the argument name. Here is an example:
```js
#!/usr/bin/env node
/**
* Module dependencies.
*/
var program = require('commander');
program
.version('0.1.0')
.command('rmdir <dir> [otherDirs...]')
.action(function (dir, otherDirs) {
console.log('rmdir %s', dir);
if (otherDirs) {
otherDirs.forEach(function (oDir) {
console.log('rmdir %s', oDir);
});
}
});
program.parse(process.argv);
```
An `Array` is used for the value of a variadic argument. This applies to `program.args` as well as the argument passed
to your action as demonstrated above.
## Specify the argument syntax
```js
#!/usr/bin/env node
var program = require('commander');
program
.version('0.1.0')
.arguments('<cmd> [env]')
.action(function (cmd, env) {
cmdValue = cmd;
envValue = env;
});
program.parse(process.argv);
if (typeof cmdValue === 'undefined') {
console.error('no command given!');
process.exit(1);
}
console.log('command:', cmdValue);
console.log('environment:', envValue || "no environment given");
```
Angled brackets (e.g. `<cmd>`) indicate required input. Square brackets (e.g. `[env]`) indicate optional input.
## Git-style sub-commands
```js
// file: ./examples/pm
var program = require('commander');
program
.version('0.1.0')
.command('install [name]', 'install one or more packages')
.command('search [query]', 'search with optional query')
.command('list', 'list packages installed', {isDefault: true})
.parse(process.argv);
```
When `.command()` is invoked with a description argument, no `.action(callback)` should be called to handle sub-commands, otherwise there will be an error. This tells commander that you're going to use separate executables for sub-commands, much like `git(1)` and other popular tools.
The commander will try to search the executables in the directory of the entry script (like `./examples/pm`) with the name `program-command`, like `pm-install`, `pm-search`.
Options can be passed with the call to `.command()`. Specifying `true` for `opts.noHelp` will remove the option from the generated help output. Specifying `true` for `opts.isDefault` will run the subcommand if no other subcommand is specified.
If the program is designed to be installed globally, make sure the executables have proper modes, like `755`.
### `--harmony`
You can enable `--harmony` option in two ways:
* Use `#! /usr/bin/env node --harmony` in the sub-commands scripts. Note some os version don’t support this pattern.
* Use the `--harmony` option when call the command, like `node --harmony examples/pm publish`. The `--harmony` option will be preserved when spawning sub-command process.
## Automated --help
The help information is auto-generated based on the information commander already knows about your program, so the following `--help` info is for free:
```
$ ./examples/pizza --help
Usage: pizza [options]
An application for pizzas ordering
Options:
-h, --help output usage information
-V, --version output the version number
-p, --peppers Add peppers
-P, --pineapple Add pineapple
-b, --bbq Add bbq sauce
-c, --cheese <type> Add the specified type of cheese [marble]
-C, --no-cheese You do not want any cheese
```
## Custom help
You can display arbitrary `-h, --help` information
by listening for "--help". Commander will automatically
exit once you are done so that the remainder of your program
does not execute causing undesired behaviours, for example
in the following executable "stuff" will not output when
`--help` is used.
```js
#!/usr/bin/env node
/**
* Module dependencies.
*/
var program = require('commander');
program
.version('0.1.0')
.option('-f, --foo', 'enable some foo')
.option('-b, --bar', 'enable some bar')
.option('-B, --baz', 'enable some baz');
// must be before .parse() since
// node's emit() is immediate
program.on('--help', function(){
console.log(' Examples:');
console.log('');
console.log(' $ custom-help --help');
console.log(' $ custom-help -h');
console.log('');
});
program.parse(process.argv);
console.log('stuff');
```
Yields the following help output when `node script-name.js -h` or `node script-name.js --help` are run:
```
Usage: custom-help [options]
Options:
-h, --help output usage information
-V, --version output the version number
-f, --foo enable some foo
-b, --bar enable some bar
-B, --baz enable some baz
Examples:
$ custom-help --help
$ custom-help -h
```
## .outputHelp(cb)
Output help information without exiting.
Optional callback cb allows post-processing of help text before it is displayed.
If you want to display help by default (e.g. if no command was provided), you can use something like:
```js
var program = require('commander');
var colors = require('colors');
program
.version('0.1.0')
.command('getstream [url]', 'get stream URL')
.parse(process.argv);
if (!process.argv.slice(2).length) {
program.outputHelp(make_red);
}
function make_red(txt) {
return colors.red(txt); //display the help text in red on the console
}
```
## .help(cb)
Output help information and exit immediately.
Optional callback cb allows post-processing of help text before it is displayed.
## Examples
```js
var program = require('commander');
program
.version('0.1.0')
.option('-C, --chdir <path>', 'change the working directory')
.option('-c, --config <path>', 'set config path. defaults to ./deploy.conf')
.option('-T, --no-tests', 'ignore test hook');
program
.command('setup [env]')
.description('run setup commands for all envs')
.option("-s, --setup_mode [mode]", "Which setup mode to use")
.action(function(env, options){
var mode = options.setup_mode || "normal";
env = env || 'all';
console.log('setup for %s env(s) with %s mode', env, mode);
});
program
.command('exec <cmd>')
.alias('ex')
.description('execute the given remote cmd')
.option("-e, --exec_mode <mode>", "Which exec mode to use")
.action(function(cmd, options){
console.log('exec "%s" using %s mode', cmd, options.exec_mode);
}).on('--help', function() {
console.log(' Examples:');
console.log();
console.log(' $ deploy exec sequential');
console.log(' $ deploy exec async');
console.log();
});
program
.command('*')
.action(function(env){
console.log('deploying "%s"', env);
});
program.parse(process.argv);
```

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('0.1.0')\n .option('-p, --peppers', 'Add peppers')\n .option('-P, --pineapple', 'Add pineapple')\n .option('-b, --bbq-sauce', '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(' - pineapple');\nif (program.bbqSauce) 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\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\nfunction collect(val, memo) {\n memo.push(val);\n return memo;\n}\n\nfunction increaseVerbosity(v, total) {\n return total + 1;\n}\n\nprogram\n .version('0.1.0')\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 .option('-c, --collect [value]', 'A repeatable value', collect, [])\n .option('-v, --verbose', 'A value that can be increased', increaseVerbosity, 0)\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(' collect: %j', program.collect);\nconsole.log(' verbosity: %j', program.verbose);\nconsole.log(' args: %j', program.args);\n```\n\n## Regular Expression\n```js\nprogram\n .version('0.1.0')\n .option('-s --size <size>', 'Pizza size', /^(large|medium|small)$/i, 'medium')\n .option('-d --drink [drink]', 'Drink', /^(coke|pepsi|izze)$/i)\n .parse(process.argv);\n \nconsole.log(' size: %j', program.size);\nconsole.log(' drink: %j', program.drink);\n```\n\n## Variadic arguments\n\n The last argument of a command can be variadic, and only the last argument. To make an argument variadic you have to\n append `...` to the argument name. Here is an example:\n\n```js\n#!/usr/bin/env node\n\n/**\n * Module dependencies.\n */\n\nvar program = require('commander');\n\nprogram\n .version('0.1.0')\n .command('rmdir <dir> [otherDirs...]')\n .action(function (dir, otherDirs) {\n console.log('rmdir %s', dir);\n if (otherDirs) {\n otherDirs.forEach(function (oDir) {\n console.log('rmdir %s', oDir);\n });\n }\n });\n\nprogram.parse(process.argv);\n```\n\n An `Array` is used for the value of a variadic argument. This applies to `program.args` as well as the argument passed\n to your action as demonstrated above.\n\n## Specify the argument syntax\n\n```js\n#!/usr/bin/env node\n\nvar program = require('commander');\n\nprogram\n .version('0.1.0')\n .arguments('<cmd> [env]')\n .action(function (cmd, env) {\n cmdValue = cmd;\n envValue = env;\n });\n\nprogram.parse(process.argv);\n\nif (typeof cmdValue === 'undefined') {\n console.error('no command given!');\n process.exit(1);\n}\nconsole.log('command:', cmdValue);\nconsole.log('environment:', envValue || \"no environment given\");\n```\nAngled brackets (e.g. `<cmd>`) indicate required input. Square brackets (e.g. `[env]`) indicate optional input.\n\n## Git-style sub-commands\n\n```js\n// file: ./examples/pm\nvar program = require('commander');\n\nprogram\n .version('0.1.0')\n .command('install [name]', 'install one or more packages')\n .command('search [query]', 'search with optional query')\n .command('list', 'list packages installed', {isDefault: true})\n .parse(process.argv);\n```\n\nWhen `.command()` is invoked with a description argument, no `.action(callback)` should be called to handle sub-commands, otherwise there will be an error. This tells commander that you're going to use separate executables for sub-commands, much like `git(1)` and other popular tools. \nThe commander will try to search the executables in the directory of the entry script (like `./examples/pm`) with the name `program-command`, like `pm-install`, `pm-search`.\n\nOptions can be passed with the call to `.command()`. Specifying `true` for `opts.noHelp` will remove the option from the generated help output. Specifying `true` for `opts.isDefault` will run the subcommand if no other subcommand is specified.\n\nIf the program is designed to be installed globally, make sure the executables have proper modes, like `755`.\n\n### `--harmony`\n\nYou can enable `--harmony` option in two ways:\n* Use `#! /usr/bin/env node --harmony` in the sub-commands scripts. Note some os version don’t support this pattern.\n* Use the `--harmony` option when call the command, like `node --harmony examples/pm publish`. The `--harmony` option will be preserved when spawning sub-command process.\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 An application for pizzas ordering\n\n Options:\n\n -h, --help output usage information\n -V, --version output the version number\n -p, --peppers Add peppers\n -P, --pineapple Add pineapple\n -b, --bbq Add bbq sauce\n -c, --cheese <type> Add the specified type of cheese [marble]\n -C, --no-cheese You do not want any cheese\n\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('commander');\n\nprogram\n .version('0.1.0')\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\nYields the following help output when `node script-name.js -h` or `node script-name.js --help` are run:\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## .outputHelp(cb)\n\nOutput help information without exiting.\nOptional callback cb allows post-processing of help text before it is displayed.\n\nIf you want to display help by default (e.g. if no command was provided), you can use something like:\n\n```js\nvar program = require('commander');\nvar colors = require('colors');\n\nprogram\n .version('0.1.0')\n .command('getstream [url]', 'get stream URL')\n .parse(process.argv);\n\n if (!process.argv.slice(2).length) {\n program.outputHelp(make_red);\n }\n\nfunction make_red(txt) {\n return colors.red(txt); //display the help text in red on the console\n}\n```\n\n## .help(cb)\n\n Output help information and exit immediately.\n Optional callback cb allows post-processing of help text before it is displayed.\n\n## Examples\n\n```js\nvar program = require('commander');\n\nprogram\n .version('0.1.0')\n .option('-C, --chdir <path>', 'change the working directory')\n .option('-c, --config <path>', 'set config path. defaults to ./deploy.conf')\n .option('-T, --no-tests', 'ignore test hook');\n\nprogram\n .command('setup [env]')\n .description('run setup commands for all envs')\n .option(\"-s, --setup_mode [mode]\", \"Which setup mode to use\")\n .action(function(env, options){\n var mode = options.setup_mode || \"normal\";\n env = env || 'all';\n console.log('setup for %s env(s) with %s mode', env, mode);\n });\n\nprogram\n .command('exec <cmd>')\n .alias('ex')\n .description('execute the given remote cmd')\n .option(\"-e, --exec_mode <mode>\", \"Which exec mode to use\")\n .action(function(cmd, options){\n console.log('exec \"%s\" using %s mode', cmd, options.exec_mode);\n }).on('--help', function() {\n console.log(' Examples:');\n console.log();\n console.log(' $ deploy exec sequential');\n console.log(' $ deploy exec async');\n console.log();\n });\n\nprogram\n .command('*')\n .action(function(env){\n console.log('deploying \"%s\"', env);\n });\n\nprogram.parse(process.argv);\n```\n\nMore Demos can be found in the [examples](https://github.com/tj/commander.js/tree/master/examples) directory.\n\n## License\n\nMIT\n\n",

# Emitter [![Build Status](https://travis-ci.org/component/emitter.png)](https://travis-ci.org/component/emitter)
Event emitter component.
## Installation
```
$ component install component/emitter
```
## API
### Emitter(obj)
The `Emitter` may also be used as a mixin. For example
a "plain" object may become an emitter, or you may
extend an existing prototype.
As an `Emitter` instance:
```js
var Emitter = require('emitter');
var emitter = new Emitter;
emitter.emit('something');
```
As a mixin:
```js
var Emitter = require('emitter');
var user = { name: 'tobi' };
Emitter(user);
user.emit('im a user');
```
As a prototype mixin:
```js
var Emitter = require('emitter');
Emitter(User.prototype);
```
### Emitter#on(event, fn)
Register an `event` handler `fn`.
### Emitter#once(event, fn)
Register a single-shot `event` handler `fn`,
removed immediately after it is invoked the
first time.
### Emitter#off(event, fn)
* Pass `event` and `fn` to remove a listener.
* Pass `event` to remove all listeners on that event.
* Pass nothing to remove all listeners on all events.
### Emitter#emit(event, ...)
Emit an `event` with variable option args.
### Emitter#listeners(event)
Return an array of callbacks, or an empty array.
### Emitter#hasListeners(event)
Check if this emitter has `event` handlers.

example
=======
``` js
var concatMap = require('concat-map');
var xs = [ 1, 2, 3, 4, 5, 6 ];
var ys = concatMap(xs, function (x) {
return x % 2 ? [ x - 0.1, x, x + 0.1 ] : [];

```
methods
=======
``` js
var concatMap = require('concat-map')
```
concatMap(xs, fn)
-----------------
Return an array of concatenated elements by calling `fn(x, i)` for each element
`x` and each index `i` in the array `xs`.
When `fn(x, i)` returns an array, its result will be concatenated with the
result array. If `fn(x, i)` returns anything else, that value will be pushed
onto the end of the result array.
install
=======
With [npm](http://npmjs.org) do:
```
npm install concat-map
```
