# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html). (Format adopted after v3.0.0.)
<!-- markdownlint-disable MD024 -->
## [4.1.1] (2020-02-02)
### Fixed
* TypeScript definition for `.action()` should include Promise for async ([#1157])
## [4.1.0] (2020-01-06)
### Added
* two routines to change how option values are handled, and eliminate name clashes with command properties ([#933] [#1102])
* see storeOptionsAsProperties and passCommandToAction in README
* `.parseAsync` to use instead of `.parse` if supply async action handlers ([#806] [#1118])
### Fixed
* Remove trailing blanks from wrapped help text ([#1096])
### Changed
* update dependencies
* extend security coverage for Commander 2.x to 2020-02-03
* improvements to README
* improvements to TypeScript definition documentation
* move old versions out of main CHANGELOG
* removed explicit use of `ts-node` in tests
## [4.0.1] (2019-11-12)
### Fixed
* display help when requested, even if there are missing required options ([#1091])
## [4.0.0] (2019-11-02)
### Added
* automatically wrap and indent help descriptions for options and commands ([#1051])
* `.exitOverride()` allows override of calls to `process.exit` for additional error handling and to keep program running ([#1040])
* support for declaring required options with `.requiredOptions()` ([#1071])
* GitHub Actions support ([#1027])
* translation links in README
### Changed
* dev: switch tests from Sinon+Should to Jest with major rewrite of tests ([#1035])
* call default subcommand even when there are unknown options ([#1047])
* *Breaking* Commander is only officially supported on Node 8 and above, and requires Node 6 ([#1053])
### Fixed
* *Breaking* keep command object out of program.args when action handler called ([#1048])
* also, action handler now passed array of unknown arguments
* complain about unknown options when program argument supplied and action handler ([#1049])
* this changes parameters to `command:*` event to include unknown arguments
* removed deprecated `customFds` option from call to `child_process.spawn` ([#1052])
* rework TypeScript declarations to bring all types into imported namespace ([#1081])
### Migration Tips
#### Testing for no arguments
If you were previously using code like:
```js
if (!program.args.length) ...
```
a partial replacement is:
```js
if (program.rawArgs.length < 3) ...
```
## [4.0.0-1] Prerelease (2019-10-08)
(Released in 4.0.0)
## [4.0.0-0] Prerelease (2019-10-01)
(Released in 4.0.0)
## [2.20.1] (2019-09-29)
### Fixed
* Improve tracking of executable subcommands.
### Changed
* update development dependencies
## [3.0.2] (2019-09-27)
### Fixed
* Improve tracking of executable subcommands.
### Changed
* update development dependencies
## [3.0.1] (2019-08-30)
### Added
* .name and .usage to README ([#1010])
* Table of Contents to README ([#1010])
* TypeScript definition for `executableFile` in CommandOptions ([#1028])
### Changed
* consistently use `const` rather than `var` in README ([#1026])
### Fixed
* help for sub commands with custom executableFile ([#1018])
## [3.0.0] / 2019-08-08
* Add option to specify executable file name ([#999])
* e.g. `.command('clone', 'clone description', { executableFile: 'myClone' })`
* Change docs for `.command` to contrast action handler vs git-style executable. ([#938] [#990])
* **Breaking** Change TypeScript to use overloaded function for `.command`. ([#938] [#990])
* Change to use straight quotes around strings in error messages (like 'this' instead of `this') ([#915])
* Add TypeScript "reference types" for node ([#974])
* Add support for hyphen as an option argument in subcommands ([#697])
* Add support for a short option flag and its value to be concatenated for action handler subcommands ([#599])
* e.g. `-p 80` can also be supplied as `-p80`
* Add executable arguments to spawn in win32, for git-style executables ([#611])
* e.g. `node --harmony myCommand.js clone`
* Add parent command as prefix of subcommand in help ([#980])
* Add optional custom description to `.version` ([#963])
* e.g. `program.version('0.0.1', '-v, --vers', 'output the current version')`
* Add `.helpOption(flags, description)` routine to customise help flags and description ([#963])
* e.g. `.helpOption('-e, --HELP', 'read more information')`
* Fix behavior of --no-* options ([#795])
* can now define both `--foo` and `--no-foo`
* **Breaking** custom event listeners: `--no-foo` on cli now emits `option:no-foo` (previously `option:foo`)
* **Breaking** default value: defining `--no-foo` after defining `--foo` leaves the default value unchanged (previously set it to false)
* allow boolean default value, such as from environment ([#987])
* Increment inspector port for spawned subcommands ([#991])
* e.g. `node --inspect myCommand.js clone`
### Migration Tips
The custom event for a negated option like `--no-foo` is `option:no-foo` (previously `option:foo`).
```js
program
.option('--no-foo')
.on('option:no-foo', () => {
console.log('removing foo');
});
```
When using TypeScript, adding a command does not allow an explicit `undefined` for an unwanted executable description (e.g
for a command with an action handler).
```js
program
.command('action1', undefined, { noHelp: true }) // No longer valid
.command('action2', { noHelp: true }) // Correct
```

## Installation
```bash
npm install commander
```
## Declaring _program_ variable
Commander exports a global object which is convenient for quick programs.
This is used in the examples in this README for brevity.
```js
const program = require('commander');
program.version('0.0.1');
```
For larger programs which may use commander in multiple ways, including unit testing, it is better to create a local Command object to use.
```js
const commander = require('commander');
const program = new commander.Command();
program.version('0.0.1');
```
## Options
Options are defined with the `.option()` method, also serving as documentation for the options. Each option can have a short flag (single character) and a long name, separated by a comma or space.
The options can be accessed as properties on the Command object. Multi-word options such as "--template-engine" are camel-cased, becoming `program.templateEngine` etc. Multiple short flags may be combined as a single arg, for example `-abc` is equivalent to `-a -b -c`.
See also optional new behaviour to [avoid name clashes](#avoiding-option-name-clashes).
### Common option types, boolean and value
The two most used option types are a boolean flag, and an option which takes a value (declared using angle brackets). Both are `undefined` unless specified on command line.
```js
const program = require('commander');
program
.option('-d, --debug', 'output extra debugging')
.option('-s, --small', 'small pizza size')
.option('-p, --pizza-type <type>', 'flavour of pizza');
program.parse(process.argv);
if (program.debug) console.log(program.opts());
console.log('pizza details:');
if (program.small) console.log('- small pizza size');
if (program.pizzaType) console.log(`- ${program.pizzaType}`);
```
```bash
$ pizza-options -d
{ debug: true, small: undefined, pizzaType: undefined }
pizza details:
$ pizza-options -p
error: option '-p, --pizza-type <type>' argument missing
$ pizza-options -ds -p vegetarian
{ debug: true, small: true, pizzaType: 'vegetarian' }
pizza details:
- small pizza size
- vegetarian
$ pizza-options --pizza-type=cheese
pizza details:
- cheese
```
`program.parse(arguments)` processes the arguments, leaving any args not consumed by the options as the `program.args` array.
### Default option value
You can specify a default value for an option which takes a value.
```js
const program = require('commander');
program
.option('-c, --cheese <type>', 'add the specified type of cheese', 'blue');
program.parse(process.argv);
console.log(`cheese: ${program.cheese}`);
```
```bash
$ pizza-options
cheese: blue
$ pizza-options --cheese stilton
cheese: stilton
```
### Other option types, negatable boolean and flag|value
You can specify a boolean option long name with a leading `no-` to set the option value to false when used.
Defined alone this also makes the option true by default.
If you define `--foo` first, adding `--no-foo` does not change the default value from what it would
otherwise be. You can specify a default boolean value for a boolean flag and it can be overridden on command line.
```js
const program = require('commander');
program
.option('--no-sauce', 'Remove sauce')
.option('--cheese <flavour>', 'cheese flavour', 'mozzarella')
.option('--no-cheese', 'plain with no cheese')
.parse(process.argv);
const sauceStr = program.sauce ? 'sauce' : 'no sauce';
const cheeseStr = (program.cheese === false) ? 'no cheese' : `${program.cheese} cheese`;
console.log(`You ordered a pizza with ${sauceStr} and ${cheeseStr}`);
```
```bash
$ pizza-options
You ordered a pizza with sauce and mozzarella cheese
$ pizza-options --sauce
error: unknown option '--sauce'
$ pizza-options --cheese=blue
You ordered a pizza with sauce and blue cheese
$ pizza-options --no-sauce --no-cheese
You ordered a pizza with no sauce and no cheese
```
You can specify an option which functions as a flag but may also take a value (declared using square brackets).
```js
const program = require('commander');
program
.option('-c, --cheese [type]', 'Add cheese with optional type');
program.parse(process.argv);
if (program.cheese === undefined) console.log('no cheese');
else if (program.cheese === true) console.log('add cheese');
else console.log(`add cheese type ${program.cheese}`);
```
```bash
$ pizza-options
no cheese
$ pizza-options --cheese
add cheese
$ pizza-options --cheese mozzarella
add cheese type mozzarella
```
### Custom option processing
You may specify a function to do custom processing of option values. The callback function receives two parameters, the user specified value and the
previous value for the option. It returns the new value for the option.
This allows you to coerce the option value 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.
```js
const program = require('commander');
function myParseInt(value, dummyPrevious) {
// parseInt takes a string and an optional radix
return parseInt(value);
}
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 <number>', 'float argument', parseFloat)
.option('-i, --integer <number>', 'integer argument', myParseInt)
.option('-v, --verbose', 'verbosity that can be increased', increaseVerbosity, 0)
.option('-c, --collect <value>', 'repeatable value', collect, [])
.option('-l, --list <items>', 'comma separated list', commaSeparatedList)
;
program.parse(process.argv);
if (program.float !== undefined) console.log(`float: ${program.float}`);
if (program.integer !== undefined) console.log(`integer: ${program.integer}`);
if (program.verbose > 0) console.log(`verbosity: ${program.verbose}`);
if (program.collect.length > 0) console.log(program.collect);
if (program.list !== undefined) console.log(program.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' ]
```
### Required option
You may specify a required (mandatory) option using `.requiredOption`. The option must be specified on the command line, or by having a default value. The method is otherwise the same as `.option` in format, taking flags and description, and optional default value or custom processing.
```js
const program = require('commander');
program
.requiredOption('-c, --cheese <type>', 'pizza must have cheese');
program.parse(process.argv);
```
```
$ pizza
error: required option '-c, --cheese <type>' not specified
```
### 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. The version flags can be named anything, but a long name is required.
```js
program.version('0.0.1', '-v, --vers', 'output the current version');
```
## Commands
You can specify (sub)commands for your top-level command using `.command`. There are two ways these can be implemented: using an action handler attached to the command, or as a separate executable file (described in more detail later). In the first parameter to `.command` you specify the command name and any command arguments. The arguments may be `<required>` or `[optional]`, and the last argument may also be `variadic...`.
For example:
```js
// Command implemented using action handler (description is supplied separately to `.command`)
// Returns new command for configuring.
program
.command('clone <source> [destination]')
.description('clone a repository into a newly created directory')
.action((source, destination) => {
console.log('clone command called');
});
// Command implemented using separate executable file (description is second parameter to `.command`)
// Returns top-level command for adding more commands.
program
.command('start <service>', 'start named service')
.command('stop [service]', 'stop named service, or all if no name supplied');
```
### Specify the argument syntax
You use `.arguments` to specify the arguments for the top-level command, and for subcommands they are included in the `.command` call. Angled brackets (e.g. `<required>`) indicate required input. Square brackets (e.g. `[optional]`) indicate optional input.
```js
const 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");
```
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. For example:
```js
const 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);
```
The variadic argument is passed to the action handler as an array. (And this also applies to `program.args`.)
### Action handler (sub)commands
You can add options to a command that uses an action handler.
The action handler gets passed a parameter for each argument you declared, and one additional argument which is the
command object itself. This command argument has the values for the command-specific options added as properties.
```js
const program = require('commander');
program
.command('rm <dir>')
.option('-r, --recursive', 'Remove recursively')
.action(function (dir, cmdObj) {
console.log('remove ' + dir + (cmdObj.recursive ? ' recursively' : ''))
})
program.parse(process.argv)
```
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 on the command line 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.
Configuration options can be passed with the call to `.command()`. Specifying `true` for `opts.noHelp` will remove the command from the generated help output.
### Git-style executable (sub)commands
When `.command()` is invoked with a description argument, this tells commander that you're going to use separate executables for sub-commands, much like `git(1)` and other popular tools.
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.
```js
// file: ./examples/pm
const program = require('commander');
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})
.parse(process.argv);
```
Configuration options can be passed with the call to `.command()`. Specifying `true` for `opts.noHelp` will remove the command from the generated help output. Specifying `true` for `opts.isDefault` will run the subcommand if no other subcommand is specified.
Specifying a name with `executableFile` will override the default constructed name.
If the program is designed to be installed globally, make sure the executables have proper modes, like `755`.
## 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:
```bash
$ ./examples/pizza --help
Usage: pizza [options]
An application for pizzas ordering
Options:
-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 (default: "marble")
-C, --no-cheese You do not want any cheese
-h, --help output usage information
```
### 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 behaviors, for example
in the following executable "stuff" will not output when
`--help` is used.
```js
#!/usr/bin/env node
const 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('')
console.log('Examples:');
console.log(' $ custom-help --help');
console.log(' $ custom-help -h');
});
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:
```Text
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
```
### .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
```
### .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
const program = require('commander');
const 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
}
```
### .helpOption(flags, description)
Override the default help flags and description.
```js
program
.helpOption('-e, --HELP', 'read more information');
```
### .help(cb)
Output help information and exit immediately.
Optional callback cb allows post-processing of help text before it is displayed.
## 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.verbose;
});
// error on unknown commands
program.on('command:*', function () {
console.error('Invalid command: %s\nSee --help for a list of available commands.', program.args.join(' '));
process.exit(1);
});
```
## Bits and pieces
### Avoiding option name clashes
The original and default behaviour is that the option values are stored
as properties on the program, and the action handler is passed a
command object with the options values stored as properties.
This is very convenient to code, but the downside is possible clashes with
existing properties of Command.
There are two new routines to change the behaviour, and the default behaviour may change in the future:
- `storeOptionsAsProperties`: whether to store option values as properties on command object, or store separately (specify false) and access using `.opts()`
- `passCommandToAction`: whether to pass command to action handler,
or just the options (specify false)
```js
// file: ./examples/storeOptionsAsProperties.action.js
program
.storeOptionsAsProperties(false)
.passCommandToAction(false);
program
.name('my-program-name')
.option('-n,--name <name>');
program
.command('show')
.option('-a,--action <action>')
.action((options) => {
console.log(options.action);
});
program.parse(process.argv);
const programOptions = program.opts();
console.log(programOptions.name);
```
### TypeScript
The Commander package includes its TypeScript Definition file, but also requires the node types which you need to install yourself. e.g.
```bash
npm install commander
npm install --save-dev @types/node
```
If you use `ts-node` and git-style sub-commands written as `.ts` files, you need to call your program through node to get the sub-commands called correctly. e.g.
```bash
node -r ts-node/register pm.ts
```
### Node options such as `--harmony`
You can enable `--harmony` option in two ways:
- Use `#! /usr/bin/env node --harmony` in the sub-commands 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 sub-command process.
### Node debugging
If you are using the node inspector for [debugging](https://nodejs.org/en/docs/guides/debugging-getting-started/) git-style executable (sub)commands using `node --inspect` et al,
the inspector port is incremented by 1 for the spawned subcommand.
### Override exit 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...
}
```
## Examples
```js
const 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){
const 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('');
console.log('Examples:');
console.log('');
console.log(' $ deploy exec sequential');
console.log(' $ deploy exec async');
});
program
.command('*')
.action(function(env){
console.log('deploying "%s"', env);
});
program.parse(process.argv);
```
