|
||||
|
||||
> [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
|
||||
|
||||
You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.
|
||||
|
||||
<img src="screenshot.svg" width="900">
|
||||
|
||||
## Install
|
||||
|
||||
```
|
||||
$ npm install ansi-styles
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
```js
|
||||
const style = require('ansi-styles');
|
||||
|
||||
console.log(`${style.green.open}Hello world!${style.green.close}`);
|
||||
|
||||
|
||||
// Color conversion between 16/256/truecolor
|
||||
// NOTE: If conversion goes to 16 colors or 256 colors, the original color
|
||||
// may be degraded to fit that color palette. This means terminals
|
||||
// that do not support 16 million colors will best-match the
|
||||
// original color.
|
||||
console.log(style.bgColor.ansi.hsl(120, 80, 72) + 'Hello world!' + style.bgColor.close);
|
||||
console.log(style.color.ansi256.rgb(199, 20, 250) + 'Hello world!' + style.color.close);
|
||||
console.log(style.color.ansi16m.hex('#abcdef') + 'Hello world!' + style.color.close);
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
Each style has an `open` and `close` property.
|
||||
|
||||
## Styles
|
||||
|
||||
### Modifiers
|
||||
|
||||
- `reset`
|
||||

|
||||
- `dim`
|
||||
- `italic` *(Not widely supported)*
|
||||
- `underline`
|
||||
- `inverse`
|
||||
- `hidden`
|
||||
- `strikethrough` *(Not widely supported)*
|
||||
|
||||

||||
- `black`
|
||||
- `red`
|
||||

|
||||
- `yellow`
|
||||
- `blue`
|
||||
- `magenta`
|
||||
- `cyan`
|
||||
- `white`
|
||||
- `blackBright` (alias: `gray`, `grey`)
|
||||
- `redBright`
|
||||
- `greenBright`
|
||||
- `yellowBright`
|
||||
- `blueBright`
|
||||

|
||||
- `bgBlue`
|
||||
- `bgMagenta`
|
||||
- `bgCyan`
|
||||
- `bgWhite`
|
||||
- `bgBlackBright` (alias: `bgGray`, `bgGrey`)
|
||||
- `bgRedBright`
|
||||
- `bgGreenBright`
|
||||
- `bgYellowBright`
|
||||
- `bgBlueBright`
|
||||
- `bgMagentaBright`
|
||||
- `bgCyanBright`
|
||||
- `bgWhiteBright`
|
||||
|
||||
## Advanced usage
|
||||
|
||||
By default, you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
|
||||
|
||||
- `style.modifier`
|
||||
- `style.color`
|
||||
- `style.bgColor`
|
||||
|
||||
###### Example
|
||||
|
||||
```js
|
||||
console.log(style.color.green.open);
|
||||
```
|
||||
|
||||
Raw escape codes (i.e. without the CSI escape prefix `\u001B[` and render mode postfix `m`) are available under `style.codes`, which returns a `Map` with the open codes as keys and close codes as values.
|
||||
|
||||
###### Example
|
||||
|
||||
```js
|
||||
console.log(style.codes.get(36));
|
||||
//=> 39
|
||||
```
|
||||
|
||||
## [256 / 16 million (TrueColor) support](https://gist.github.com/XVilka/8346728)
|
||||
|
||||
`ansi-styles` uses the [`color-convert`](https://github.com/Qix-/color-convert) package to allow for converting between various colors and ANSI escapes, with support for 256 and 16 million colors.
|
||||
|
||||
The following color spaces from `color-convert` are supported:
|
||||
|
||||
- `rgb`
|
||||
- `hex`
|
||||
- `keyword`
|
||||
- `hsl`
|
||||
- `hsv`
|
||||
- `hwb`
|
||||
- `ansi`
|
||||
- `ansi256`
|
||||
|
||||
To use these, call the associated conversion function with the intended output, for example:
|
||||
|
||||
```js
|
||||
style.color.ansi.rgb(100, 200, 15); // RGB to 16 color ansi foreground code
|
||||
style.bgColor.ansi.rgb(100, 200, 15); // RGB to 16 color ansi background code
|
||||
|
||||
style.color.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
|
||||
style.bgColor.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
|
||||
|
||||
style.color.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color foreground code
|
||||
style.bgColor.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color background code
|
||||
```

|
||||
## Install
|
||||
|
||||
```console
|
||||
$ npm install chalk
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
```js
|
||||
const chalk = require('chalk');
|
||||
|
||||
console.log(chalk.blue('Hello world!'));
|
||||
```
|
||||
|
||||
Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
|
||||
|
||||
```js
|
||||
const chalk = require('chalk');
|
||||
const log = console.log;
|
||||
|
||||
// Combine styled and normal strings
|
||||
log(chalk.blue('Hello') + ' World' + chalk.red('!'));
|
||||
|
||||
// Compose multiple styles using the chainable API
|
||||
log(chalk.blue.bgRed.bold('Hello world!'));
|
||||
|
||||
// Pass in multiple arguments
|
||||
log(chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz'));
|
||||
|
||||
// Nest styles
|
||||
log(chalk.red('Hello', chalk.underline.bgBlue('world') + '!'));
|
||||
|
||||
// Nest styles of the same type even (color, underline, background)
|
||||
log(chalk.green(
|
||||
'I am a green line ' +
|
||||
chalk.blue.underline.bold('with a blue substring') +
|
||||
' that becomes green again!'
|
||||
));
|
||||
|
||||
// ES2015 template literal
|
||||
log(`
|
||||
CPU: ${chalk.red('90%')}
|
||||
RAM: ${chalk.green('40%')}
|
||||
DISK: ${chalk.yellow('70%')}
|
||||
`);
|
||||
|
||||
// ES2015 tagged template literal
|
||||
log(chalk`
|
||||
CPU: {red ${cpu.totalPercent}%}
|
||||
RAM: {green ${ram.used / ram.total * 100}%}
|
||||
DISK: {rgb(255,131,0) ${disk.used / disk.total * 100}%}
|
||||
`);
|
||||
|
||||
// Use RGB colors in terminal emulators that support it.
|
||||
log(chalk.keyword('orange')('Yay for orange colored text!'));
|
||||
log(chalk.rgb(123, 45, 67).underline('Underlined reddish color'));
|
||||
log(chalk.hex('#DEADED').bold('Bold gray!'));
|
||||
```
|
||||
|
||||
Easily define your own themes:
|
||||
|
||||
```js
|
||||
const chalk = require('chalk');
|
||||
|
||||
const error = chalk.bold.red;
|
||||
const warning = chalk.keyword('orange');
|
||||
|
||||
console.log(error('Error!'));
|
||||
console.log(warning('Warning!'));
|
||||
```
|
||||
|
||||
Take advantage of console.log [string substitution](https://nodejs.org/docs/latest/api/console.html#console_console_log_data_args):
|
||||
|
||||
```js
|
||||
const name = 'Sindre';
|
||||
console.log(chalk.green('Hello %s'), name);
|
||||
//=> 'Hello Sindre'
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
### chalk.`<style>[.<style>...](string, [string...])`
|
||||
|
||||
Example: `chalk.red.bold.underline('Hello', 'world');`
|
||||
|
||||
Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that `chalk.red.yellow.green` is equivalent to `chalk.green`.
|
||||
|
||||
Multiple arguments will be separated by space.
|
||||
|
||||
### chalk.level
|
||||
|
||||
Specifies the level of color support.
|
||||
|
||||
Color support is automatically detected, but you can override it by setting the `level` property. You should however only do this in your own code as it applies globally to all Chalk consumers.
|
||||
|
||||
If you need to change this in a reusable module, create a new instance:
|
||||
|
||||
```js
|
||||
const ctx = new chalk.Instance({level: 0});
|
||||
```
|
||||
|
||||
| Level | Description |
|
||||
| :---: | :--- |
|
||||
| `0` | All colors disabled |
|
||||
| `1` | Basic color support (16 colors) |
|
||||
| `2` | 256 color support |
|
||||
| `3` | Truecolor support (16 million colors) |
|
||||
|
||||
### chalk.supportsColor
|
||||
|
||||
Detect whether the terminal [supports color](https://github.com/chalk/supports-color). Used internally and handled for you, but exposed for convenience.
|
||||
|
||||
Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, use the environment variable `FORCE_COLOR=1` (level 1), `FORCE_COLOR=2` (level 2), or `FORCE_COLOR=3` (level 3) to forcefully enable color, or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
|
||||
|
||||
Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
|
||||
|
||||
### chalk.stderr and chalk.stderr.supportsColor
|
||||
|
||||
`chalk.stderr` contains a separate instance configured with color support detected for `stderr` stream instead of `stdout`. Override rules from `chalk.supportsColor` apply to this too. `chalk.stderr.supportsColor` is exposed for convenience.
|
||||
|
||||
## Styles
|
||||
|
||||
### Modifiers
|
||||
|
||||
- `reset` - Resets the current color chain.
|
||||
- `bold` - Make text bold.
|
||||
- `dim` - Emitting only a small amount of light.
|
||||
- `italic` - Make text italic. *(Not widely supported)*
|
||||
- `underline` - Make text underline. *(Not widely supported)*
|
||||
- `inverse`- Inverse background and foreground colors.
|
||||
- `hidden` - Prints the text, but makes it invisible.
|
||||
- `strikethrough` - Puts a horizontal line through the center of the text. *(Not widely supported)*
|
||||
- `visible`- Prints the text only when Chalk has a color level > 0. Can be useful for things that are purely cosmetic.
|
||||
|
||||
### Colors
|
||||
|
||||
- `black`
|
||||
- `red`
|
||||
- `green`

|
||||

|
||||
|
||||
## Tagged template literal
|
||||
|
||||
Chalk can be used as a [tagged template literal](https://exploringjs.com/es6/ch_template-literals.html#_tagged-template-literals).
|
||||
|
||||
```js
|
||||
const chalk = require('chalk');
|
||||
|
||||
const miles = 18;
|
||||
const calculateFeet = miles => miles * 5280;
|
||||
|
||||
console.log(chalk`
|
||||
There are {bold 5280 feet} in a mile.
|
||||
In {bold ${miles} miles}, there are {green.bold ${calculateFeet(miles)} feet}.
|
||||
`);
|
||||
```
|
||||
|
||||
Blocks are delimited by an opening curly brace (`{`), a style, some content, and a closing curly brace (`}`).
|
||||
|
||||
Template styles are chained exactly like normal Chalk styles. The following three statements are equivalent:
|
||||
|
||||
```js
|
||||
console.log(chalk.bold.rgb(10, 100, 200)('Hello!'));
|
||||
console.log(chalk.bold.rgb(10, 100, 200)`Hello!`);
|
||||
console.log(chalk`{bold.rgb(10,100,200) Hello!}`);
|
||||
```
|
||||
|
||||
Note that function styles (`rgb()`, `hsl()`, `keyword()`, etc.) may not contain spaces between parameters.
|
||||
|
||||
All interpolated values (`` chalk`${foo}` ``) are converted to strings via the `.toString()` method. All curly braces (`{` and `}`) in interpolated value strings are escaped.
|
||||
|
||||
## 256 and Truecolor color support
|
||||
|
||||
Chalk supports 256 colors and [Truecolor](https://gist.github.com/XVilka/8346728) (16 million colors) on supported terminal apps.
|
||||
|
||||
Colors are downsampled from 16 million RGB values to an ANSI color format that is supported by the terminal emulator (or by specifying `{level: n}` as a Chalk option). For example, Chalk configured to run at level 1 (basic color support) will downsample an RGB value of #FF0000 (red) to 31 (ANSI escape for red).
|
||||
|
||||
Examples:
|
||||
|
||||
- `chalk.hex('#DEADED').underline('Hello, world!')`
|
||||
- `chalk.keyword('orange')('Some orange text')`
|
||||
- `chalk.rgb(15, 100, 204).inverse('Hello!')`
|
||||
|
||||
Background versions of these models are prefixed with `bg` and the first level of the module capitalized (e.g. `keyword` for foreground colors and `bgKeyword` for background colors).
|
||||
|
||||
- `chalk.bgHex('#DEADED').underline('Hello, world!')`
|
||||
- `chalk.bgKeyword('orange')('Some orange text')`
|
||||
- `chalk.bgRgb(15, 100, 204).inverse('Hello!')`
|
||||
|
||||
The following color models can be used:
|
||||
|
||||
- [`rgb`](https://en.wikipedia.org/wiki/RGB_color_model) - Example: `chalk.rgb(255, 136, 0).bold('Orange!')`
|
||||
- [`hex`](https://en.wikipedia.org/wiki/Web_colors#Hex_triplet) - Example: `chalk.hex('#FF8800').bold('Orange!')`
|
||||
- [`keyword`](https://www.w3.org/wiki/CSS/Properties/color/keywords) (CSS keywords) - Example: `chalk.keyword('orange').bold('Orange!')`
|
||||
- [`hsl`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsl(32, 100, 50).bold('Orange!')`
|
||||
- [`hsv`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsv(32, 100, 100).bold('Orange!')`
|
||||
- [`hwb`](https://en.wikipedia.org/wiki/HWB_color_model) - Example: `chalk.hwb(32, 0, 50).bold('Orange!')`
|
||||
- [`ansi`](https://en.wikipedia.org/wiki/ANSI_escape_code#3/4_bit) - Example: `chalk.ansi(31).bgAnsi(93)('red on yellowBright')`
|
||||
- [`ansi256`](https://en.wikipedia.org/wiki/ANSI_escape_code#8-bit) - Example: `chalk.bgAnsi256(194)('Honeydew, more or less')`
|
||||
|
||||
## Windows
|
||||
|
||||
If you're on Windows, do yourself a favor and use [Windows Terminal](https://github.com/microsoft/terminal) instead of `cmd.exe`.
|
||||
|
||||
## Origin story
|
||||
|
||||
[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68) and the package is unmaintained. Although there are other packages, they either do too much or not enough. Chalk is a clean and focused alternative.
|
||||
|
||||
## chalk for enterprise
|
||||
|
||||
Available as part of the Tidelift Subscription.
|
||||
|
||||
The maintainers of chalk and thousands of other packages are working with Tidelift to deliver commercial support and maintenance for the open source dependencies you use to build your applications. Save time, reduce risk, and improve code health, while paying the maintainers of the exact dependencies you use.

# color-convert

|

[![Build Status](https://travis-ci.org/Qix-/color-convert.svg?branch=master)](https://travis-ci.org/Qix-/color-convert)
|
||||
|
||||
Color-convert is a color conversion library for JavaScript and node.
|
||||
It converts all ways between `rgb`, `hsl`, `hsv`, `hwb`, `cmyk`, `ansi`, `ansi16`, `hex` strings, and CSS `keyword`s (will round to closest):
|
||||
|
||||
```js
|
||||
var convert = require('color-convert');
|
||||
|
||||
convert.rgb.hsl(140, 200, 100); // [96, 48, 59]

# API
|
||||
|
||||
Simply get the property of the _from_ and _to_ conversion that you're looking for.
|
||||
|
||||
All functions have a rounded and unrounded variant. By default, return values are rounded. To get the unrounded (raw) results, simply tack on `.raw` to the function.
|
||||
|
||||
All 'from' functions have a hidden property called `.channels` that indicates the number of channels the function expects (not including alpha).
|
||||
|
||||
```js
|
||||
var convert = require('color-convert');
|
||||
|
||||
// Hex to LAB
|
||||
convert.hex.lab('DEADBF'); // [ 76, 21, -2 ]
|
||||
convert.hex.lab.raw('DEADBF'); // [ 75.56213190997677, 20.653827952644754, -2.290532499330533 ]
|
||||
|
||||
// RGB to CMYK
|
||||
convert.rgb.cmyk(167, 255, 4); // [ 35, 0, 98, 0 ]
|
||||
convert.rgb.cmyk.raw(167, 255, 4); // [ 34.509803921568626, 0, 98.43137254901961, 0 ]
|
||||
```
|
||||
|
||||
### Arrays
|
||||
All functions that accept multiple arguments also support passing an array.
|
||||
|
||||
Note that this does **not** apply to functions that convert from a color that only requires one value (e.g. `keyword`, `ansi256`, `hex`, etc.)
|
||||
|
||||
```js
|
||||
var convert = require('color-convert');
|
||||
|
||||
convert.rgb.hex(123, 45, 67); // '7B2D43'
|
||||
convert.rgb.hex([123, 45, 67]); // '7B2D43'
|
||||
```
|
||||
|
||||
## Routing
|
||||
|
||||
Conversions that don't have an _explicitly_ defined conversion (in [conversions.js](conversions.js)), but can be converted by means of sub-conversions (e.g. XYZ -> **RGB** -> CMYK), are automatically routed together. This allows just about any color model supported by `color-convert` to be converted to any other model, so long as a sub-conversion path exists. This is also true for conversions requiring more than one step in between (e.g. LCH -> **LAB** -> **XYZ** -> **RGB** -> Hex).
|
||||
|
||||
Keep in mind that extensive conversions _may_ result in a loss of precision, and exist only to be complete. For a list of "direct" (single-step) conversions, see [conversions.js](conversions.js).
|
||||
|
||||

|
||||
- regression for legacy `command('*')` and call when command line includes options ([#1464])
|
||||
- regression for `on('command:*', ...)` and call when command line includes unknown options ([#1464])

||||
|
||||

|
||||
|
||||
## [7.0.0] (2021-01-15)
|
||||
|
||||
### Added
|
||||
|
||||
- `.enablePositionalOptions()` to let program and subcommand reuse same option ([#1427])
|
||||
- `.passThroughOptions()` to pass options through to other programs without needing `--` ([#1427])
|
||||
- `.allowExcessArguments(false)` to show an error message if there are too many command-arguments on command line for the action handler ([#1409])
|
||||
- `.configureOutput()` to modify use of stdout and stderr or customise display of errors ([#1387])
|
||||
- use `.addHelpText()` to add text before or after the built-in help, for just current command or also for all subcommands ([#1296])
|
||||
- enhance Option class ([#1331])
|
||||
- allow hiding options from help
|
||||
- allow restricting option arguments to a list of choices
|
||||
- allow setting how default value is shown in help
|
||||
- `.createOption()` to support subclassing of automatically created options (like `.createCommand()`) ([#1380])
|
||||
- refactor the code generating the help into a separate public Help class ([#1365])
|
||||
- support sorting subcommands and options in help
|
||||
- support specifying wrap width (columns)
|
||||
- allow subclassing Help class
|
||||
- allow configuring Help class without subclassing
|
||||
|
||||
### Changed
|
||||
|
||||
- *Breaking:* options are stored safely by default, not as properties on the command ([#1409])
|
||||
- this especially affects accessing options on program, use `program.opts()`
|
||||
- revert behaviour with `.storeOptionsAsProperties()`
|
||||
- *Breaking:* action handlers are passed options and command separately ([#1409])
|
||||
- deprecated callback parameter to `.help()` and `.outputHelp()` (removed from README) ([#1296])
|
||||
- *Breaking:* errors now displayed using `process.stderr.write()` instead of `console.error()`
|
||||
- deprecate `.on('--help')` (removed from README) ([#1296])
|
||||
- initialise the command description to empty string (previously undefined) ([#1365])
|
||||
- document and annotate deprecated routines ([#1349])
|
||||
|
||||
### Fixed
|
||||
|
||||
- wrapping bugs in help ([#1365])
|
||||
- first line of command description was wrapping two characters early
|
||||
- pad width calculation was not including help option and help command
|
||||
- pad width calculation was including hidden options and commands
|
||||
- improve backwards compatibility for custom command event listeners ([#1403])
|
||||
|
||||
### Deleted
|
||||
|
||||
- *Breaking:* `.passCommandToAction()` ([#1409])
|
||||
- no longer needed as action handler is passed options and command
|
||||
- *Breaking:* "extra arguments" parameter to action handler ([#1409])
|
||||
- if being used to detect excess arguments, there is now an error available by setting `.allowExcessArguments(false)`
|
||||
|
||||
### Migration Tips
|
||||
|
||||
The biggest change is the parsed option values. Previously the options were stored by default as properties on the command object, and now the options are stored separately.
|
||||
|
||||
If you wish to restore the old behaviour and get running quickly you can call `.storeOptionsAsProperties()`.
|
||||
To allow you to move to the new code patterns incrementally, the action handler will be passed the command _twice_,
|
||||
to match the new "options" and "command" parameters (see below).
|
||||
|
||||
**program options**
|
||||
|
||||
Use the `.opts()` method to access the options. This is available on any command but is used most with the program.
|
||||
|
||||
```js
|
||||
program.option('-d, --debug');
|
||||
program.parse();
|
||||
// Old code before Commander 7
|
||||
if (program.debug) console.log(`Program name is ${program.name()}`);
|
||||
```
|
||||
|
||||
```js
|
||||
// New code
|
||||
const options = program.opts();
|
||||
if (options.debug) console.log(`Program name is ${program.name()}`);
|
||||
```
|
||||
|
||||
**action handler**
|
||||
|
||||
The action handler gets passed a parameter for each command-argument you declared. Previously by default the next parameter was the command object with the options as properties. Now the next two parameters are instead the options and the command. If you
|
||||
only accessed the options there may be no code changes required.
|
||||
|
||||
```js
|
||||
program
|
||||
.command('compress <filename>')
|
||||
.option('-t, --trace')
|
||||
// Old code before Commander 7
|
||||
.action((filename, cmd)) => {
|
||||
if (cmd.trace) console.log(`Command name is ${cmd.name()}`);
|
||||
});
|
||||
```
|
||||
|
||||
```js
|
||||
// New code
|
||||
.action((filename, options, command)) => {
|
||||
if (options.trace) console.log(`Command name is ${command.name()}`);
|
||||
});
|
||||
```
|
||||
|
||||
If you already set `.storeOptionsAsProperties(false)` you may still need to adjust your code.
|
||||
|
||||
```js
|
||||
program
|
||||
.command('compress <filename>')
|
||||
.storeOptionsAsProperties(false)
|
||||
.option('-t, --trace')
|
||||
// Old code before Commander 7
|
||||
.action((filename, command)) => {
|
||||
if (command.opts().trace) console.log(`Command name is ${command.name()}`);
|
||||
});
|
||||
```
|
||||
|
||||
```js
|
||||
// New code
|
||||
.action((filename, options, command)) => {
|
||||
if (command.opts().trace) console.log(`Command name is ${command.name()}`);
|
||||
});
|
||||
```

||||
* `parseExpectedArgs` is now private ([#1149])
|
||||
|
||||
### Migration Tips
|
||||
|
||||
If you use `.on('command:*')` or more complicated tests to detect an unrecognised subcommand, you may be able to delete the code and rely on the default behaviour.
|
||||
|
||||
If you use `program.args` or more complicated tests to detect a missing subcommand, you may be able to delete the code and rely on the default behaviour.
|
||||
|
||||
If you use `.command('*')` to add a default command, you may be be able to switch to `isDefault:true` with a named command.
|
||||
|
||||
If you want to continue combining short options with optional values as though they were boolean flags, set `combineFlagAndOptionalValue(false)`
|
||||
to expand `-fb` to `-f -b` rather than `-f b`.

## 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 { Command } = require('commander');
|
||||
const program = new Command();
|
||||
program.version('0.0.1');
|
||||
```
|
||||
|
||||
For named imports in ECMAScript modules, import from `commander/esm.mjs`.
|
||||
|
||||
```js
|
||||
// index.mjs
|
||||
import { Command } from 'commander/esm.mjs';
|
||||
const program = new Command();
|
||||
```
|
||||
|
||||
And in TypeScript:
|
||||
|
||||
```ts
|
||||
// index.ts
|
||||
import { Command } from 'commander';
|
||||
const program = new Command();
|
||||
```
|
||||
|
||||
|
||||
## 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 or vertical bar ('|').
|
||||
|
||||
The parsed options can be accessed by calling `.opts()` on a `Command` object, and are passed to the action handler. Multi-word options such as "--template-engine" are camel-cased, becoming `program.opts().templateEngine` etc.
|
||||
|
||||
Multiple short flags may optionally be combined in a single argument following the dash: boolean flags, followed by a single option taking a value (possibly followed by the value).
|
||||
For example `-a -b -p 80` may be written as `-ab -p80` or even `-abp80`.
|
||||
|
||||
You can use `--` to indicate the end of the options, and any remaining arguments will be used without being interpreted.
|
||||
|
||||
By default options on the command line are not positional, and can be specified before or after other arguments.
|
||||
|
||||
### Common option types, boolean and value
|
||||
|
||||
The two most used option types are a boolean option, and an option which takes its value
|
||||
from the following argument (declared with angle brackets like `--expect <value>`). Both are `undefined` unless specified on command line.
|
||||
|
||||
Example file: [options-common.js](./examples/options-common.js)
|
||||
|
||||
```js
|
||||
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);
|
||||
|
||||
const options = program.opts();
|
||||
if (options.debug) console.log(options);
|
||||
console.log('pizza details:');
|
||||
if (options.small) console.log('- small pizza size');
|
||||
if (options.pizzaType) console.log(`- ${options.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 program options in the `program.args` array. The parameter is optional and defaults to `process.argv`.
|
||||
|
||||
### Default option value
|
||||
|
||||
You can specify a default value for an option which takes a value.
|
||||
|
||||
Example file: [options-defaults.js](./examples/options-defaults.js)
|
||||
|
||||
```js
|
||||
program
|
||||
.option('-c, --cheese <type>', 'add the specified type of cheese', 'blue');
|
||||
|
||||
program.parse();
|
||||
|
||||
console.log(`cheese: ${program.opts().cheese}`);
|
||||
```
|
||||
|
||||
```bash
|
||||
$ pizza-options
|
||||
cheese: blue
|
||||
$ pizza-options --cheese stilton
|
||||
cheese: stilton
|
||||
```
|
||||
|
||||
### Other option types, negatable boolean and boolean|value
|
||||
|
||||
You can define 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 option and it can be overridden on command line.
|
||||
|
||||
Example file: [options-negatable.js](./examples/options-negatable.js)
|
||||
|
||||
```js
|
||||
program
|
||||
.option('--no-sauce', 'Remove sauce')
|
||||
.option('--cheese <flavour>', 'cheese flavour', 'mozzarella')
|
||||
.option('--no-cheese', 'plain with no cheese')
|
||||
.parse();
|
||||
|
||||
const options = program.opts();
|
||||
const sauceStr = options.sauce ? 'sauce' : 'no sauce';
|
||||
const cheeseStr = (options.cheese === false) ? 'no cheese' : `${options.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 may be used as a boolean option but may optionally take an option-argument
|
||||
(declared with square brackets like `--optional [value]`).
|
||||
|
||||
Example file: [options-boolean-or-value.js](./examples/options-boolean-or-value.js)
|
||||
|
||||
```js
|
||||
program
|
||||
.option('-c, --cheese [type]', 'Add cheese with optional type');
|
||||
|
||||
program.parse(process.argv);
|
||||
|
||||
const options = program.opts();
|
||||
if (options.cheese === undefined) console.log('no cheese');
|
||||
else if (options.cheese === true) console.log('add cheese');
|
||||
else console.log(`add cheese type ${options.cheese}`);
|
||||
```
|
||||
|
||||
```bash
|
||||
$ pizza-options
|
||||
no cheese
|
||||
$ pizza-options --cheese
|
||||
add cheese
|
||||
$ pizza-options --cheese mozzarella
|
||||
add cheese type mozzarella
|
||||
```
|
||||
|
||||
For information about possible ambiguous cases, see [options taking varying arguments](./docs/options-taking-varying-arguments.md).
|
||||
|
||||
### Required option
|
||||
|
||||
You may specify a required (mandatory) option using `.requiredOption`. The option must have a value after parsing, usually specified on the command line, or perhaps from a default value (say from environment). The method is otherwise the same as `.option` in format, taking flags and description, and optional default value or custom processing.
|
||||
|
||||
Example file: [options-required.js](./examples/options-required.js)
|
||||
|
||||
```js
|
||||
program
|
||||
.requiredOption('-c, --cheese <type>', 'pizza must have cheese');
|
||||
|
||||
program.parse();
|
||||
```
|
||||
|
||||
```bash
|
||||
$ pizza
|
||||
error: required option '-c, --cheese <type>' not specified
|
||||
```
|
||||
|
||||
### Variadic option
|
||||
|
||||
You may make an option variadic by appending `...` to the value placeholder when declaring the option. 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 <numbers...>', '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 file: [options-extra.js](./examples/options-extra.js)
|
||||
|
||||
```js
|
||||
program
|
||||
.addOption(new Option('-s, --secret').hideHelp())
|
||||
.addOption(new Option('-t, --timeout <delay>', 'timeout in seconds').default(60, 'one minute'))
|
||||
.addOption(new Option('-d, --drink <size>', 'drink size').choices(['small', 'medium', 'large']));
|
||||
```
|
||||
|
||||
```bash
|
||||
$ extra --help
|
||||
Usage: help [options]
|
||||
|
||||
Options:
|
||||
-t, --timeout <delay> timeout in seconds (default: one minute)
|
||||
-d, --drink <size> drink cup size (choices: "small", "medium", "large")
|
||||
-h, --help display help for command
|
||||
|
||||
$ extra --drink huge
|
||||
error: option '-d, --drink <size>' argument 'huge' is invalid. Allowed choices are small, medium, large.
|
||||
```
|
||||
|
||||
### 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.InvalidOptionArgumentError('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 <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();
|
||||
|
||||
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 and any command-arguments. The arguments may be `<required>` 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 <source> [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 (description is second parameter to `.command`)
|
||||
// Returns `this` for adding more commands.
|
||||
program
|
||||
.command('start <service>', '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)).
|
||||
|
||||
### Specify the argument syntax
|
||||
|
||||
You use `.arguments` to specify the expected command-arguments for the top-level command, and for subcommands they are usually
|
||||
included in the `.command` call. Angled brackets (e.g. `<required>`) indicate required command-arguments.
|
||||
Square brackets (e.g. `[optional]`) indicate optional command-arguments.
|
||||
You can optionally describe the arguments in the help by supplying a hash as second parameter to `.description()`.
|
||||
|
||||
Example file: [arguments.js](./examples/arguments.js)
|
||||
|
||||
```js
|
||||
program
|
||||
.version('0.1.0')
|
||||
.arguments('<username> [password]')
|
||||
.description('test command', {
|
||||
username: 'user to login',
|
||||
password: 'password for user, if required'
|
||||
})
|
||||
.action((username, password) => {
|
||||
console.log('username:', username);
|
||||
console.log('environment:', password || 'no password 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
|
||||
program
|
||||
.version('0.1.0')
|
||||
.command('rmdir <dirs...>')
|
||||
.action(function (dirs) {
|
||||
dirs.forEach((dir) => {
|
||||
console.log('rmdir %s', dir);
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
The variadic argument is passed to the action handler as an array.
|
||||
|
||||
### 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
|
||||
.arguments('<name>')
|
||||
.option('-t, --title <honorific>', '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`.
|
||||
|
||||
## 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 <type> 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 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)
|
||||
|
||||
```
|
||||
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;
|
||||
});
|
||||
|
||||
program.on('command:*', function (operands) {
|
||||
console.error(`error: unknown command '${operands[0]}'`);
|
||||
const availableCommands = program.commands.map(cmd => cmd.name());
|
||||
mySuggestBestMatch(operands[0], availableCommands);
|
||||
process.exitCode = 1;
|
||||
});
|
||||
```
|
||||
|
||||
## 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:
|
||||
|
||||
```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 line and passed through as a command-argument in the second:
|
||||
|
||||
```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))
|
||||
});
|
||||
```
|
||||
|
||||

||||
## 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 <type>', '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 <path>', 'set config path', './deploy.conf');
|
||||
|
||||
program
|
||||
.command('setup [env]')
|
||||
.description('run setup commands for all envs')
|
||||
.option('-s, --setup_mode <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 <script>')
|
||||
.alias('ex')
|
||||
.description('execute the given remote cmd')
|
||||
.option('-e, --exec_mode <mode>', 'Which exec mode to use', 'fast')
|

## Support
|
||||
|
||||
The current version of Commander is fully supported on Long Term Support versions of node, and requires at least node v10.
|
||||
(For older versions of node, use an older version of Commander. Commander version 2.x has the widest support.)
|
||||
|
||||
The main forum for free and community support is the project [Issues](https://github.com/tj/commander.js/issues) on GitHub.
|
||||
|
||||

Returns an `Object` with a `stdout` and `stderr` property for testing either streams. Each property is an `Object`, or `false` if color is not supported.
|
||||
|
||||
The `stdout`/`stderr` objects specifies a level of support for color through a `.level` property and a corresponding flag:
|
||||
|
||||
- `.level = 1` and `.hasBasic = true`: Basic color support (16 colors)
|
||||
- `.level = 2` and `.has256 = true`: 256 color support
|
||||
- `.level = 3` and `.has16m = true`: Truecolor support (16 million colors)
|
||||
|
||||
|
||||
## Info
|
||||
|
||||
It obeys the `--color` and `--no-color` CLI flags.
|
||||
|
||||
For situations where using `--color` is not possible, use the environment variable `FORCE_COLOR=1` (level 1), `FORCE_COLOR=2` (level 2), or `FORCE_COLOR=3` (level 3) to forcefully enable color, or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
|
||||
|
||||
Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
