On the command line you +can then specify multiple option-arguments, and the parsed option value will be an array. The extra arguments +are read until the first argument starting with a dash. The special argument `--` stops option processing entirely. If a value +is specified in the same argument as the option then no further values are read. + +Example file: [options-variadic.js](./examples/options-variadic.js) + +```js +program + .option('-n, --number ', 'specify numbers') + .option('-l, --letter [letters...]', 'specify letters'); + +program.parse(); + +console.log('Options: ', program.opts()); +console.log('Remaining arguments: ', program.args); +``` + +```bash +$ collect -n 1 2 3 --letter a b c +Options: { number: [ '1', '2', '3' ], letter: [ 'a', 'b', 'c' ] } +Remaining arguments: [] +$ collect --letter=A -n80 operand +Options: { number: [ '80' ], letter: [ 'A' ] } +Remaining arguments: [ 'operand' ] +$ collect --letter -n 1 -n 2 3 -- operand +Options: { number: [ '1', '2', '3' ], letter: true } +Remaining arguments: [ 'operand' ] +``` + +For information about possible ambiguous cases, see [options taking varying arguments](./docs/options-taking-varying-arguments.md). + +### Version option + +The optional `version` method adds handling for displaying the command version. The default option flags are `-V` and `--version`, and when present the command prints the version number and exits. + +```js +program.version('0.0.1'); +``` + +```bash +$ ./examples/pizza -V +0.0.1 +``` + +You may change the flags and description by passing additional parameters to the `version` method, using +the same syntax for flags as the `option` method. + +```js +program.version('0.0.1', '-v, --vers', 'output the current version'); +``` + +### More configuration + +You can add most options using the `.option()` method, but there are some additional features available +by constructing an `Option` explicitly for less common cases. + +Example files: [options-extra.js](./examples/options-extra.js), [options-env.js](./examples/options-env.js) + +```js +program + .addOption(new Option('-s, --secret').hideHelp()) + .addOption(new Option('-t, --timeout ', 'timeout in seconds').default(60, 'one minute')) + .addOption(new Option('-d, --drink ', 'drink size').choices(['small', 'medium', 'large'])) + .addOption(new Option('-p, --port ', 'port number').env('PORT')); +``` + +```bash +$ extra --help +Usage: help [options] + +Options: + -t, --timeout timeout in seconds (default: one minute) + -d, --drink drink cup size (choices: "small", "medium", "large") + -p, --port port number (env: PORT) + -h, --help display help for command + +$ extra --drink huge +error: option '-d, --drink ' argument 'huge' is invalid. Allowed choices are small, medium, large. + +$ PORT=80 extra +Options: { timeout: 60, port: '80' } +``` + +### Custom option processing + +You may specify a function to do custom processing of option-arguments. The callback function receives two parameters, +the user specified option-argument and the previous value for the option. It returns the new value for the option. + +This allows you to coerce the option-argument to the desired type, or accumulate values, or do entirely custom processing. + +You can optionally specify the default/starting value for the option after the function parameter. + +Example file: [options-custom-processing.js](./examples/options-custom-processing.js) + +```js +function myParseInt(value, dummyPrevious) { + // parseInt takes a string and a radix + const parsedValue = parseInt(value, 10); + if (isNaN(parsedValue)) { + throw new commander.InvalidArgumentError('Not a number.'); + } + return parsedValue; +} + +function increaseVerbosity(dummyValue, previous) { + return previous + 1; +} + +function collect(value, previous) { + return previous.concat([value]); +} + +function commaSeparatedList(value, dummyPrevious) { + return value.split(','); +} + +program + .option('-f, --float ', 'float argument', parseFloat) + .option('-i, --integer ', 'integer argument', myParseInt) + .option('-v, --verbose', 'verbosity that can be increased', increaseVerbosity, 0) + .option('-c, --collect ', 'repeatable value', collect, []) + .option('-l, --list ', 'comma separated list', commaSeparatedList) +; + +program.parse(); + +const options = program.opts(); +if (options.float !== undefined) console.log(`float: ${options.float}`); +if (options.integer !== undefined) console.log(`integer: ${options.integer}`); +if (options.verbose > 0) console.log(`verbosity: ${options.verbose}`); +if (options.collect.length > 0) console.log(options.collect); +if (options.list !== undefined) console.log(options.list); +``` + +```bash +$ custom -f 1e2 +float: 100 +$ custom --integer 2 +integer: 2 +$ custom -v -v -v +verbose: 3 +$ custom -c a -c b -c c +[ 'a', 'b', 'c' ] +$ custom --list x,y,z +[ 'x', 'y', 'z' ] +``` + +## Commands + +You can specify (sub)commands using `.command()` or `.addCommand()`. There are two ways these can be implemented: using an action handler attached to the command, or as a stand-alone executable file (described in more detail later). The subcommands may be nested ([example](./examples/nestedCommands.js)). + +In the first parameter to `.command()` you specify the command name. You may append the command-arguments after the command name, or specify them separately using `.argument()`. The arguments may be `` or `[optional]`, and the last argument may also be `variadic...`. + +You can use `.addCommand()` to add an already configured subcommand to the program. + +For example: + +```js +// Command implemented using action handler (description is supplied separately to `.command`) +// Returns new command for configuring. +program + .command('clone [destination]') + .description('clone a repository into a newly created directory') + .action((source, destination) => { + console.log('clone command called'); + }); + +// Command implemented using stand-alone executable file, indicated by adding description as second parameter to `.command`. +// Returns `this` for adding more commands. +program + .command('start ', 'start named service') + .command('stop [service]', 'stop named service, or all if no name supplied'); + +// Command prepared separately. +// Returns `this` for adding more commands. +program + .addCommand(build.makeBuildCommand()); +``` + +Configuration options can be passed with the call to `.command()` and `.addCommand()`. Specifying `hidden: true` will +remove the command from the generated help output. Specifying `isDefault: true` will run the subcommand if no other +subcommand is specified ([example](./examples/defaultCommand.js)). + +### Command-arguments + +For subcommands, you can specify the argument syntax in the call to `.command()` (as shown above). This +is the only method usable for subcommands implemented using a stand-alone executable, but for other subcommands +you can instead use the following method. + +To configure a command, you can use `.argument()` to specify each expected command-argument. +You supply the argument name and an optional description. The argument may be `` or `[optional]`. +You can specify a default value for an optional command-argument. + +Example file: [argument.js](./examples/argument.js) + +```js +program + .version('0.1.0') + .argument('', 'user to login') + .argument('[password]', 'password for user, if required', 'no password given') + .action((username, password) => { + console.log('username:', username); + console.log('password:', password); + }); +``` + + The last argument of a command can be variadic, and only the last argument. To make an argument variadic you + append `...` to the argument name. A variadic argument is passed to the action handler as an array. For example: + +```js +program + .version('0.1.0') + .command('rmdir') + .argument('') + .action(function (dirs) { + dirs.forEach((dir) => { + console.log('rmdir %s', dir); + }); + }); +``` + +There is a convenience method to add multiple arguments at once, but without descriptions: + +```js +program + .arguments(' '); +``` + +#### More configuration + +There are some additional features available by constructing an `Argument` explicitly for less common cases. + +Example file: [arguments-extra.js](./examples/arguments-extra.js) + +```js +program + .addArgument(new commander.Argument('', 'drink cup size').choices(['small', 'medium', 'large'])) + .addArgument(new commander.Argument('[timeout]', 'timeout in seconds').default(60, 'one minute')) +``` + +#### Custom argument processing + +You may specify a function to do custom processing of command-arguments (like for option-arguments). +The callback function receives two parameters, the user specified command-argument and the previous value for the argument. +It returns the new value for the argument. + +The processed argument values are passed to the action handler, and saved as `.processedArgs`. + +You can optionally specify the default/starting value for the argument after the function parameter. + +Example file: [arguments-custom-processing.js](./examples/arguments-custom-processing.js) + +```js +program + .command('add') + .argument('', 'integer argument', myParseInt) + .argument('[second]', 'integer argument', myParseInt, 1000) + .action((first, second) => { + console.log(`${first} + ${second} = ${first + second}`); + }) +; +``` + +### Action handler + +The action handler gets passed a parameter for each command-argument you declared, and two additional parameters +which are the parsed options and the command object itself. + +Example file: [thank.js](./examples/thank.js) + +```js +program + .argument('') + .option('-t, --title ', 'title to use before name') + .option('-d, --debug', 'display some debugging') + .action((name, options, command) => { + if (options.debug) { + console.error('Called %s with options %o', command.name(), options); + } + const title = options.title ? `${options.title} ` : ''; + console.log(`Thank-you ${title}${name}`); + }); +``` + +You may supply an `async` action handler, in which case you call `.parseAsync` rather than `.parse`. + +```js +async function run() { /* code goes here */ } + +async function main() { + program + .command('run') + .action(run); + await program.parseAsync(process.argv); +} +``` + +A command's options and arguments on the command line are validated when the command is used. Any unknown options or missing arguments will be reported as an error. You can suppress the unknown option checks with `.allowUnknownOption()`. By default it is not an error to +pass more arguments than declared, but you can make this an error with `.allowExcessArguments(false)`. + +### Stand-alone executable (sub)commands + +When `.command()` is invoked with a description argument, this tells Commander that you're going to use stand-alone executables for subcommands. +Commander will search the executables in the directory of the entry script (like `./examples/pm`) with the name `program-subcommand`, like `pm-install`, `pm-search`. +You can specify a custom name with the `executableFile` configuration option. + +You handle the options for an executable (sub)command in the executable, and don't declare them at the top-level. + +Example file: [pm](./examples/pm) + +```js +program + .version('0.1.0') + .command('install [name]', 'install one or more packages') + .command('search [query]', 'search with optional query') + .command('update', 'update installed packages', { executableFile: 'myUpdateSubCommand' }) + .command('list', 'list packages installed', { isDefault: true }); + +program.parse(process.argv); +``` + +If the program is designed to be installed globally, make sure the executables have proper modes, like `755`. + +### Life cycle hooks + +You can add callback hooks to a command for life cycle events. + +Example file: [hook.js](./examples/hook.js) + +```js +program + .option('-t, --trace', 'display trace statements for commands') + .hook('preAction', (thisCommand, actionCommand) => { + if (thisCommand.opts().trace) { + console.log(`About to call action handler for subcommand: ${actionCommand.name()}`); + console.log('arguments: %O', actionCommand.args); + console.log('options: %o', actionCommand.opts()); + } + }); +``` + +The callback hook can be `async`, in which case you call `.parseAsync` rather than `.parse`. You can add multiple hooks per event. + +The supported events are: + +- `preAction`: called before action handler for this command and its subcommands +- `postAction`: called after action handler for this command and its subcommands + +The hook is passed the command it was added to, and the command running the action handler. + +## Automated help + +The help information is auto-generated based on the information commander already knows about your program. The default +help option is `-h,--help`. + +Example file: [pizza](./examples/pizza) + +```bash +$ node ./examples/pizza --help +Usage: pizza [options] + +An application for pizza ordering + +Options: + -p, --peppers Add peppers + -c, --cheese Add the specified type of cheese (default: "marble") + -C, --no-cheese You do not want any cheese + -h, --help display help for command +``` + +A `help` command is added by default if your command has subcommands. It can be used alone, or with a subcommand name to show +further help for the subcommand. These are effectively the same if the `shell` program has implicit help: + +```bash +shell help +shell --help + +shell help spawn +shell spawn --help +``` + +### Custom help + +You can add extra text to be displayed along with the built-in help. + +Example file: [custom-help](./examples/custom-help) + +```js +program + .option('-f, --foo', 'enable some foo'); + +program.addHelpText('after', ` + +Example call: + $ custom-help --help`); +``` + +Yields the following help output: + +```Text +Usage: custom-help [options] + +Options: + -f, --foo enable some foo + -h, --help display help for command + +Example call: + $ custom-help --help +``` + +The positions in order displayed are: + +- `beforeAll`: add to the program for a global banner or header +- `before`: display extra information before built-in help +- `after`: display extra information after built-in help +- `afterAll`: add to the program for a global footer (epilog) + +The positions "beforeAll" and "afterAll" apply to the command and all its subcommands. + +The second parameter can be a string, or a function returning a string. The function is passed a context object for your convenience. The properties are: + +- error: a boolean for whether the help is being displayed due to a usage error +- command: the Command which is displaying the help + +### Display help after errors + +The default behaviour for usage errors is to just display a short error message. +You can change the behaviour to show the full help or a custom help message after an error. + +```js +program.showHelpAfterError(); +// or +program.showHelpAfterError('(add --help for additional information)'); +``` + +```sh +$ pizza --unknown +error: unknown option '--unknown' +(add --help for additional information) +``` + +You can also show suggestions after an error for an unknown command or option. + +```js +program.showSuggestionAfterError(); +``` + +```sh +$ pizza --hepl +error: unknown option '--hepl' +(Did you mean --help?) +``` + +### Display help from code + +`.help()`: display help information and exit immediately. You can optionally pass `{ error: true }` to display on stderr and exit with an error status. + +`.outputHelp()`: output help information without exiting. You can optionally pass `{ error: true }` to display on stderr. + +`.helpInformation()`: get the built-in command help information as a string for processing or displaying yourself. + +### .usage and .name + +These allow you to customise the usage description in the first line of the help. The name is otherwise +deduced from the (full) program arguments. Given: + +```js +program + .name("my-command") + .usage("[global options] command") +``` + +The help will start with: + +```Text +Usage: my-command [global options] command +``` + +### .helpOption(flags, description) + +By default every command has a help option. Override the default help flags and description. Pass false to disable the built-in help option. + +```js +program + .helpOption('-e, --HELP', 'read more information'); +``` + +### .addHelpCommand() + +A help command is added by default if your command has subcommands. You can explicitly turn on or off the implicit help command with `.addHelpCommand()` and `.addHelpCommand(false)`. + +You can both turn on and customise the help command by supplying the name and description: + +```js +program.addHelpCommand('assist [command]', 'show assistance'); +``` + +### More configuration + +The built-in help is formatted using the Help class. +You can configure the Help behaviour by modifying data properties and methods using `.configureHelp()`, or by subclassing using `.createHelp()` if you prefer. + +The data properties are: + +- `helpWidth`: specify the wrap width, useful for unit tests +- `sortSubcommands`: sort the subcommands alphabetically +- `sortOptions`: sort the options alphabetically + +There are methods getting the visible lists of arguments, options, and subcommands. There are methods for formatting the items in the lists, with each item having a _term_ and _description_. Take a look at `.formatHelp()` to see how they are used. + +Example file: [configure-help.js](./examples/configure-help.js) + +```js +program.configureHelp({ + sortSubcommands: true, + subcommandTerm: (cmd) => cmd.name() // Just show the name, instead of short usage. +}); +``` + +## Custom event listeners + +You can execute custom actions by listening to command and option events. + +```js +program.on('option:verbose', function () { + process.env.VERBOSE = this.opts().verbose; +}); +``` + +## Bits and pieces + +### .parse() and .parseAsync() + +The first argument to `.parse` is the array of strings to parse. You may omit the parameter to implicitly use `process.argv`. + +If the arguments follow different conventions than node you can pass a `from` option in the second parameter: + +- 'node': default, `argv[0]` is the application and `argv[1]` is the script being run, with user parameters after that +- 'electron': `argv[1]` varies depending on whether the electron application is packaged +- 'user': all of the arguments from the user + +For example: + +```js +program.parse(process.argv); // Explicit, node conventions +program.parse(); // Implicit, and auto-detect electron +program.parse(['-f', 'filename'], { from: 'user' }); +``` + +### Parsing Configuration + +If the default parsing does not suit your needs, there are some behaviours to support other usage patterns. + +By default program options are recognised before and after subcommands. To only look for program options before subcommands, use `.enablePositionalOptions()`. This lets you use +an option for a different purpose in subcommands. + +Example file: [positional-options.js](./examples/positional-options.js) + +With positional options, the `-b` is a program option in the first line and a subcommand option in the second line: + +```sh +program -b subcommand +program subcommand -b +``` + +By default options are recognised before and after command-arguments. To only process options that come +before the command-arguments, use `.passThroughOptions()`. This lets you pass the arguments and following options through to another program +without needing to use `--` to end the option processing. +To use pass through options in a subcommand, the program needs to enable positional options. + +Example file: [pass-through-options.js](./examples/pass-through-options.js) + +With pass through options, the `--port=80` is a program option in the first line and passed through as a command-argument in the second line: + +```sh +program --port=80 arg +program arg --port=80 +``` + +By default the option processing shows an error for an unknown option. To have an unknown option treated as an ordinary command-argument and continue looking for options, use `.allowUnknownOption()`. This lets you mix known and unknown options. + +By default the argument processing does not display an error for more command-arguments than expected. +To display an error for excess arguments, use`.allowExcessArguments(false)`. + +### Legacy options as properties + +Before Commander 7, the option values were stored as properties on the command. +This was convenient to code but the downside was possible clashes with +existing properties of `Command`. You can revert to the old behaviour to run unmodified legacy code by using `.storeOptionsAsProperties()`. + +```js +program + .storeOptionsAsProperties() + .option('-d, --debug') + .action((commandAndOptions) => { + if (commandAndOptions.debug) { + console.error(`Called ${commandAndOptions.name()}`); + } + }); +``` + +### TypeScript + +If you use `ts-node` and stand-alone executable subcommands written as `.ts` files, you need to call your program through node to get the subcommands called correctly. e.g. + +```bash +node -r ts-node/register pm.ts +``` + +### createCommand() + +This factory function creates a new command. It is exported and may be used instead of using `new`, like: + +```js +const { createCommand } = require('commander'); +const program = createCommand(); +``` + +`createCommand` is also a method of the Command object, and creates a new command rather than a subcommand. This gets used internally +when creating subcommands using `.command()`, and you may override it to +customise the new subcommand (example file [custom-command-class.js](./examples/custom-command-class.js)). + +### Node options such as `--harmony` + +You can enable `--harmony` option in two ways: + +- Use `#! /usr/bin/env node --harmony` in the subcommands scripts. (Note Windows does not 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 subcommand process. + +### Debugging stand-alone executable subcommands + +An executable subcommand is launched as a separate child process. + +If you are using the node inspector for [debugging](https://nodejs.org/en/docs/guides/debugging-getting-started/) executable subcommands using `node --inspect` et al, +the inspector port is incremented by 1 for the spawned subcommand. + +If you are using VSCode to debug executable subcommands you need to set the `"autoAttachChildProcesses": true` flag in your launch.json configuration. + +### Override exit and output handling + +By default Commander calls `process.exit` when it detects errors, or after displaying the help or version. You can override +this behaviour and optionally supply a callback. The default override throws a `CommanderError`. + +The override callback is passed a `CommanderError` with properties `exitCode` number, `code` string, and `message`. The default override behaviour is to throw the error, except for async handling of executable subcommand completion which carries on. The normal display of error messages or version or help +is not affected by the override which is called after the display. + +```js +program.exitOverride(); + +try { + program.parse(process.argv); +} catch (err) { + // custom processing... +} +``` + +By default Commander is configured for a command-line application and writes to stdout and stderr. +You can modify this behaviour for custom applications. In addition, you can modify the display of error messages. + +Example file: [configure-output.js](./examples/configure-output.js) + +```js +function errorColor(str) { + // Add ANSI escape codes to display text in red. + return `\x1b[31m${str}\x1b[0m`; +} + +program + .configureOutput({ + // Visibly override write routines as example! + writeOut: (str) => process.stdout.write(`[OUT] ${str}`), + writeErr: (str) => process.stdout.write(`[ERR] ${str}`), + // Highlight errors in color. + outputError: (str, write) => write(errorColor(str)) + }); +``` + +### Additional documentation + +There is more information available about: + +- [deprecated](./docs/deprecated.md) features still supported for backwards compatibility +- [options taking varying arguments](./docs/options-taking-varying-arguments.md) + +## Examples + +In a single command program, you might not need an action handler. + +Example file: [pizza](./examples/pizza) + +```js +const { program } = require('commander'); + +program + .description('An application for pizza ordering') + .option('-p, --peppers', 'Add peppers') + .option('-c, --cheese ', 'Add the specified type of cheese', 'marble') + .option('-C, --no-cheese', 'You do not want any cheese'); + +program.parse(); + +const options = program.opts(); +console.log('you ordered a pizza with:'); +if (options.peppers) console.log(' - peppers'); +const cheese = !options.cheese ? 'no' : options.cheese; +console.log(' - %s cheese', cheese); +``` + +In a multi-command program, you will have action handlers for each command (or stand-alone executables for the commands). + +Example file: [deploy](./examples/deploy) + +```js +const { Command } = require('commander'); +const program = new Command(); + +program + .version('0.0.1') + .option('-c, --config ', 'set config path', './deploy.conf'); + +program + .command('setup [env]') + .description('run setup commands for all envs') + .option('-s, --setup_mode ', 'Which setup mode to use', 'normal') + .action((env, options) => { + env = env || 'all'; + console.log('read config from %s', program.opts().config); + console.log('setup for %s env(s) with %s mode', env, options.setup_mode); + }); + +program + .command('exec
