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. - -Note that multi-word options starting with `--no` prefix negate the boolean value of the following word. For example, `--no-sauce` sets the value of `program.sauce` to false. - -```js -#!/usr/bin/env node - -/** - * Module dependencies. - */ - -var program = require('commander'); - -program - .option('--no-sauce', 'Remove sauce') - .parse(process.argv); - -console.log('you ordered a pizza'); -if (program.sauce) console.log(' with sauce'); -else console.log(' without sauce'); -``` - -## Version option - -Calling the `version` implicitly adds the `-V` and `--version` options to the command. -When either of these options is present, the command prints the version number and exits. - - $ ./examples/pizza -V - 0.0.1 - -If you want your program to respond to the `-v` option instead of the `-V` option, simply pass custom flags to the `version` method using the same syntax as the `option` method. - -```js -program - .version('0.0.1', '-v, --version') -``` - -The version flags can be named anything, but the long option is required. - -## Command-specific options - -You can attach options to a command. - -```js -#!/usr/bin/env node - -var program = require('commander'); - -program - .command('rm ') - .option('-r, --recursive', 'Remove recursively') - .action(function (dir, cmd) { - console.log('remove ' + dir + (cmd.recursive ? ' recursively' : '')) - }) - -program.parse(process.argv) -``` - -A command's options are validated when the command is used. Any unknown options will be reported as an error. However, if an action-based command does not define an action, then the options are not validated. - -## 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] ') - .option('-i, --integer ', 'An integer argument', parseInt) - .option('-f, --float ', 'A float argument', parseFloat) - .option('-r, --range ..', 'A range', range) - .option('-l, --list ', '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 ', '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 [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(' [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. ``) 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 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 ', 'change the working directory') - .option('-c, --config ', '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 ') - .alias('ex') - .description('execute the given remote cmd') - .option("-e, --exec_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); -``` - -More Demos can be found in the [examples](https://github.com/tj/commander.js/tree/master/examples) directory. - -## License - -MIT
