## Description :
Yargs helps you build interactive command line tools, by parsing arguments and generating an elegant user interface.
It gives you:
* commands and (grouped) options (`my-program.js serve --port=5000`).
* a dynamically generated help menu based on your arguments.
>
* bash-completion shortcuts for commands and options.
* and [tons more](/docs/api.md).
## Installation
Stable version:
```bash
npm i yargs
```
Bleeding edge version with the most recent features:
```bash
npm i yargs@next
```
## Usage :
### Simple Example
````javascript
#!/usr/bin/env node
const argv = require('yargs').argv
if (argv.ships > 3 && argv.distance < 53.5) {
console.log('Plunder more riffiwobbles!')
} else {
console.log('Retreat from the xupptumblers!')
}
````
```bash
$ ./plunder.js --ships=4 --distance=22
Plunder more riffiwobbles!
$ ./plunder.js --ships 12 --distance 98.7
Retreat from the xupptumblers!
```
### Complex Example
```javascript
#!/usr/bin/env node
require('yargs') // eslint-disable-line
.command('serve [port]', 'start the server', (yargs) => {
yargs
.positional('port', {
describe: 'port to bind on',
default: 5000
})
}, (argv) => {
if (argv.verbose) console.info(`start server on :${argv.port}`)
serve(argv.port)
})
.option('verbose', {
alias: 'v',
type: 'boolean',
description: 'Run with verbose logging'
})
.argv
```
Run the example above with `--help` to see the help for the application.

## Commands
Yargs provides a powerful set of tools for composing modular command-driven-applications.
In this section we cover some of the advanced features available in this API:
### Default Commands
To specify a default command use the string `*` or `$0`. A default command
will be run if the positional arguments provided match no known
commands. tldr; default commands allow you to define the entry point to your
application using a similar API to subcommands.
```js
const argv = require('yargs')
.command('$0', 'the default command', () => {}, (argv) => {
console.log('this command will be run by default')
})
.argv
```
The command defined above will be executed if the program
is run with `./my-cli.js --x=22`.
Default commands can also be used as a command alias, like so:
```js
const argv = require('yargs')
.command(['serve', '$0'], 'the serve command', () => {}, (argv) => {
console.log('this command will be run by default')
})
.argv
```
The command defined above will be executed if the program
is run with `./my-cli.js --x=22`, or with `./my-cli.js serve --x=22`.
### Positional Arguments
Commands can accept _optional_ and _required_ positional arguments. Required
positional arguments take the form ``, and optional arguments
take the form `[bar]`. The parsed positional arguments will be populated in
`argv`:
```js
yargs.command('get [proxy]', 'make a get HTTP request')
.help()
.argv
```
#### Positional Argument Aliases
Aliases can be provided for positional arguments using the `|` character.
As an example, suppose our application allows either a username _or_
an email as the first argument:
```js
yargs.command('get [password]', 'fetch a user by username or email.')
.help()
.argv
```
In this way, both `argv.username` and `argv.email` would be populated with the
same value when the command is executed.
#### Variadic Positional Arguments
The last positional argument can optionally accept an array of
values, by using the `..` operator:
```js
yargs.command('download [files..]', 'download several files')
.help()
.argv
```
#### Describing Positional Arguments
You can use the method [`.positional()`](/docs/api.md#positionalkey-opt) in a command's builder function to describe and configure a positional argument:
```js
yargs.command('get [proxy]', 'make a get HTTP request', (yargs) => {
yargs.positional('source', {
describe: 'URL to fetch content from',
type: 'string',
default: 'http://www.google.com'
}).positional('proxy', {
describe: 'optional proxy URL'
})
})
.help()
.argv
```
### Command Execution
When a command is given on the command line, yargs will execute the following:
1. push the command into the current context
2. reset non-global configuration
3. apply command configuration via the `builder`, if given
4. parse and validate args from the command line, including positional args
5. if validation succeeds, run the `handler` function, if given
6. pop the command from the current context
### Command Aliases
You can define aliases for a command by putting the command and all of its
aliases into an array.
Alternatively, a command module may specify an `aliases` property, which may be
a string or an array of strings. All aliases defined via the `command` property
and the `aliases` property will be concatenated together.
The first element in the array is considered the canonical command, which may
define positional arguments, and the remaining elements in the array are
considered aliases. Aliases inherit positional args from the canonical command,
and thus any positional args defined in the aliases themselves are ignored.
If either the canonical command or any of its aliases are given on the command
line, the command will be executed.
```js
#!/usr/bin/env node
require('yargs')
.command(['start [app]', 'run', 'up'], 'Start up an app', {}, (argv) => {
console.log('starting up the', argv.app || 'default', 'app')
})
.command({
command: 'configure [value]',
aliases: ['config', 'cfg'],
desc: 'Set a config variable',
builder: (yargs) => yargs.default('value', 'true'),
handler: (argv) => {
console.log(`setting ${argv.key} to ${argv.value}`)
}
})
.demandCommand()
.help()
.wrap(72)
.argv
```
```
$ ./svc.js help
Commands:
start [app] Start up an app [aliases: run, up]
configure [value] Set a config variable [aliases: config, cfg]
Options:
--help Show help [boolean]
$ ./svc.js cfg concurrency 4
setting concurrency to 4
$ ./svc.js run web
starting up the web app
```
### Providing a Command Module
For complicated commands you can pull the logic into a module. A module
simply needs to export:
* `exports.command`: string (or array of strings) that executes this command when given on the command line, first string may contain positional args
* `exports.aliases`: array of strings (or a single string) representing aliases of `exports.command`, positional args defined in an alias are ignored
* `exports.describe`: string used as the description for the command in help text, use `false` for a hidden command
* `exports.builder`: object declaring the options the command accepts, or a function accepting and returning a yargs instance
* `exports.handler`: a function which will be passed the parsed argv.
```js
// my-module.js
exports.command = 'get [proxy]'
exports.describe = 'make a get HTTP request'
exports.builder = {
banana: {
default: 'cool'
},
batman: {
default: 'sad'
}
}
exports.handler = function (argv) {
// do something with argv.
}
```
You then register the module like so:
```js
yargs.command(require('my-module'))
.help()
.argv
```
Or if the module does not export `command` and `describe` (or if you just want to override them):
```js
yargs.command('get [proxy]', 'make a get HTTP request', require('my-module'))
.help()
.argv
```
#### Testing a Command Module
If you want to test a command in its entirety you can test it like this:
```js
it("returns help output", async () => {
// Initialize parser using the command module
const parser = yargs.command(require('./my-command-module')).help();
// Run the command module with --help as argument
const output = await new Promise((resolve) => {
parser.parse("--help", (err, argv, output) => {
resolve(output);
})
});
// Verify the output is correct
expect(output).toBe(expect.stringContaining("helpful message"));
});
```
This example uses [jest](https://github.com/facebook/jest) as a test runner, but the concept is independent of framework.
.commandDir(directory, [opts])
------------------------------
Apply command modules from a directory relative to the module calling this method.
This allows you to organize multiple commands into their own modules under a
single directory and apply all of them at once instead of calling
`.command(require('./dir/module'))` multiple times.
By default, it ignores subdirectories. This is so you can use a directory
structure to represent your command hierarchy, where each command applies its
subcommands using this method in its builder function. See the example below.
Note that yargs assumes all modules in the given directory are command modules
and will error if non-command modules are encountered. In this scenario, you
can either move your module to a different directory or use the `exclude` or
`visit` option to manually filter it out. More on that below.
`directory` is a relative directory path as a string (required).
`opts` is an options object (optional). The following options are valid:
- `recurse`: boolean, default `false`
Look for command modules in all subdirectories and apply them as a flattened
(non-hierarchical) list.
- `extensions`: array of strings, default `['js']`
The types of files to look for when requiring command modules.
- `visit`: function
A synchronous function called for each command module encountered. Accepts
`commandObject`, `pathToFile`, and `filename` as arguments. Returns
`commandObject` to include the command; any falsy value to exclude/skip it.
- `include`: RegExp or function
Whitelist certain modules. See [`require-directory` whitelisting](https://www.npmjs.com/package/require-directory#whitelisting) for details.
- `exclude`: RegExp or function
Blacklist certain modules. See [`require-directory` blacklisting](https://www.npmjs.com/package/require-directory#blacklisting) for details.
### Example command hierarchy using `.commandDir()`
Desired CLI:
```sh
$ myapp --help
$ myapp init
$ myapp remote --help
$ myapp remote add base http://yargs.js.org
$ myapp remote prune base
$ myapp remote prune base fork whatever
```
Directory structure:
```
myapp/
├─ cli.js
└─ cmds/
├─ init.js
├─ remote.js
└─ remote_cmds/
├─ add.js
└─ prune.js
```
cli.js:
```js
#!/usr/bin/env node
require('yargs')
.commandDir('cmds')
.demandCommand()
.help()
.argv
```
cmds/init.js:
```js
exports.command = 'init [dir]'
exports.desc = 'Create an empty repo'
exports.builder = {
dir: {
default: '.'
}
}
exports.handler = function (argv) {
console.log('init called for dir', argv.dir)
}
```
cmds/remote.js:
```js
exports.command = 'remote '
exports.desc = 'Manage set of tracked repos'
exports.builder = function (yargs) {
return yargs.commandDir('remote_cmds')
}
exports.handler = function (argv) {}
```
cmds/remote_cmds/add.js:
```js
exports.command = 'add '
exports.desc = 'Add remote named for repo at url '
exports.builder = {}
exports.handler = function (argv) {
console.log('adding remote %s at url %s', argv.name, argv.url)
}
```
cmds/remote_cmds/prune.js:
```js
exports.command = 'prune [names..]'
exports.desc = 'Delete tracked branches gone stale for remotes'
exports.builder = {}
exports.handler = function (argv) {
console.log('pruning remotes %s', [].concat(argv.name).concat(argv.names).join(', '))
}
```
## Building Configurable CLI Apps
One of the goals of yargs has been to examine practices common in the
JavaScript CLI community, and to make it easy to apply these
conventions to your own application.
One useful set of conventions that has emerged is around how applications
allow users to extend and customize their functionality.
### .rc files
It's common for libraries, e.g., [Babel](https://babeljs.io/docs/usage/babelrc/), [ESLint](https://github.com/eslint/eslint#configuration), to allow you to
provide configuration by populating a `.rc` file.
Yargs' [`config()`](/docs/api.md#config), combined with the module [find-up](https://www.npmjs.com/package/find-up), makes it easy to
implement `.rc` functionality:
```js
const findUp = require('find-up')
const fs = require('fs')
const configPath = findUp.sync(['.myapprc', '.myapprc.json'])
const config = configPath ? JSON.parse(fs.readFileSync(configPath)) : {}
const argv = require('yargs')
.config(config)
.argv
```
### Providing Configuration in Your package.json
Another common practice is to allow users to provide configuration via
a reserved field in the package.json. You can configure [nyc](https://github.com/istanbuljs/nyc#configuring-nyc) or [babel](https://babeljs.io/docs/usage/babelrc/#lookup-behavior), for instance,
using the `nyc` and `babel` key respectively:
```json
{
"nyc": {
"watermarks": {
"lines": [80, 95],
"functions": [80, 95],
"branches": [80, 95],
"statements": [80, 95]
}
}
}
```
Yargs gives you this functionality using the [`pkgConf()`](/docs/api.md#config)
method:
```js
const argv = require('yargs')
.pkgConf('nyc')
.argv
```
### Creating a Plugin Architecture
Both [`pkgConf()`](/docs/api.md#config) and [`config()`](/docs/api.md#config) support
the `extends` keyword. `extends` allows you to inherit configuration from [other npm modules](https://www.npmjs.com/package/@istanbuljs/nyc-config-babel), making it
possible to build plugin architectures similar to [Babel's presets](https://babeljs.io/docs/plugins/#presets):
```json
{
"nyc": {
"extends": "@istanbuljs/nyc-config-babel"
}
}
```
## Customizing Yargs' Parser
Not everyone always agrees on how `process.argv` should be interpreted;
using the [`parserConfiguration()`](/docs/api.md#parserConfiguration) method you can turn on and off some of yargs' parsing features:
```js
yargs.parserConfiguration({
"short-option-groups": true,
"camel-case-expansion": true,
"dot-notation": true,
"parse-numbers": true,
"boolean-negation": true,
"deep-merge-config": false
})
```
See the [yargs-parser](https://github.com/yargs/yargs-parser#configuration) module
for detailed documentation of this feature.
## Command finish hook
### Example
```
yargs
.command('cmd', ..., async () => {
await this.model.find()
return Promise.resolve('result value')
})
.onFinishCommand(async (resultValue) => {
await this.db.disconnect()
process.exit()
}).argv;
```
## Middleware
Sometimes you might want to transform arguments before they reach the command handler.
For example, perhaps you want to validate that credentials have been provided and otherwise load credentials from a file.
Middleware is simply a stack of functions, each of which is passed the the current parsed arguments, which it can in turn update by adding values, removing values, or overwriting values.
Diagram:
```
-------------- -------------- ---------
stdin ----> argv ----> | Middleware 1 | ----> | Middleware 2 | ---> | Command |
-------------- -------------- ---------
```
### Example Credentials Middleware
In this example, our middleware will check if the `username` and `password` is provided. If not, it will load them from `~/.credentials`, and fill in the `argv.username` and `argv.password` values.
#### Middleware function
```
const normalizeCredentials = (argv) => {
if (!argv.username || !argv.password) {
const credentials = JSON.parse(fs.readSync('~/.credentials'))
return credentials
}
return {}
}
// Add normalizeCredentials to yargs
yargs.middleware(normalizeCredentials)
```
### Example Async Credentials Middleware
This example is exactly the same however it loads the `username` and `password` asynchronously.
#### Middleware function
```
const { promisify } = require('util') // since node 8.0.0
const readFile = promisify(require('fs').readFile)
const normalizeCredentials = (argv) => {
if (!argv.username || !argv.password) {
return readFile('~/.credentials').then(data => JSON.parse(data))
}
return {}
}
// Add normalizeCredentials to yargs
yargs.middleware(normalizeCredentials)
```
#### yargs parsing configuration
```
var argv = require('yargs')
.usage('Usage: $0 [options]')
.command('login', 'Authenticate user', (yargs) =>{
return yargs.option('username')
.option('password')
} ,(argv) => {
authenticateUser(argv.username, argv.password)
},
[normalizeCredentials]
)
.argv;
```
### Using the non-singleton interface
To use yargs without running as a singleton, do:
```
const argv = require('yargs/yargs')(process.argv.slice(2))
```
This is especially useful when using yargs in a library, as library authors should not pollute the global state.
yargs-15.3.0/docs/api.md 0000664 0000000 0000000 00000131130 13631245667 0014764 0 ustar 00root root 0000000 0000000 API
=======
You can run Yargs without any configuration, and it will do its
best to parse `process.argv`:
````javascript
require('yargs').argv
````
You can also pass in the `process.argv` yourself:
````javascript
require('yargs')([ '-x', '1', '-y', '2' ]).argv
````
or use `.parse()` to do the same thing:
````javascript
require('yargs').parse([ '-x', '1', '-y', '2' ])
````
Calling `.parse()` with no arguments is equivalent to calling `yargs.argv`:
```javascript
require('yargs').parse()
```
The rest of these methods below come in just before the terminating `.argv`.
.alias(key, alias)
------------------
Set key names as equivalent such that updates to a key will propagate to aliases
and vice-versa.
Optionally `.alias()` can take an object that maps keys to aliases.
Each key of this object should be the canonical version of the option, and each
value should be a string or an array of strings.
.argv
-----
Get the arguments as a plain old object.
Arguments without a corresponding flag show up in the `argv._` array.
The script name or node command is available at `argv.$0` similarly to how `$0`
works in bash or perl.
If `yargs` is executed in an environment that embeds node and there's no script name (e.g.
[Electron](http://electron.atom.io/) or [nw.js](http://nwjs.io/)), it will ignore the first parameter since it
expects it to be the script name. In order to override this behavior, use `.parse(process.argv.slice(1))`
instead of `.argv` and the first parameter won't be ignored.
.array(key)
----------
Tell the parser to interpret `key` as an array. If `.array('foo')` is set,
`--foo foo bar` will be parsed as `['foo', 'bar']` rather than as `'foo'`.
Also, if you use the option multiple times all the values will be flattened in one array
so `--foo foo --foo bar` will be parsed as `['foo', 'bar']`
When the option is used with a positional, use `--` to tell `yargs` to stop adding values to the array.
For example: `--foo foo bar -- val` will be parsed as
```javascript
{
_: ['val'],
foo: ['foo', 'bar']
}
```
.boolean(key)
-------------
Interpret `key` as a boolean. If a non-flag option - unless `true` or `false` - follows `key` in `process.argv`, that string won't get set as the value of `key`.
`key` can be set false explicitly using the `--no-` prefix, [more](/docs/tricks.md#negate).
If `key` is an array, interpret all the elements as booleans.
.check(fn, [global=true])
----------
Check that certain conditions are met in the provided arguments.
`fn` is called with two arguments, the parsed `argv` hash and an array of options and their aliases.
If `fn` throws or returns a non-truthy value, show the thrown error, usage information, and
exit.
`global` indicates whether `check()` should be enabled both
at the top-level and for each sub-command.
.choices(key, choices)
----------------------
Limit valid values for `key` to a predefined set of `choices`, given as an array
or as an individual value.
```js
var argv = require('yargs')
.alias('i', 'ingredient')
.describe('i', 'choose your sandwich ingredients')
.choices('i', ['peanut-butter', 'jelly', 'banana', 'pickles'])
.help('help')
.argv
```
If this method is called multiple times, all enumerated values will be merged
together. Choices are generally strings or numbers, and value matching is
case-sensitive.
Optionally `.choices()` can take an object that maps multiple keys to their
choices.
Choices can also be specified as `choices` in the object given to `option()`.
```js
var argv = require('yargs')
.option('size', {
alias: 's',
describe: 'choose a size',
choices: ['xs', 's', 'm', 'l', 'xl']
})
.argv
```
.coerce(key, fn)
----------------
Provide a synchronous function to coerce or transform the value(s) given on the
command line for `key`.
The coercion function should accept one argument, representing the parsed value from
the command line (an array if multiple values are parsed for the key), and should
return a new value or throw an error. The returned value will be used as the value for
`key` (or one of its aliases) in `argv`.
If the function throws, the error will be treated as a validation
failure, delegating to either a custom [`.fail()`](#fail) handler or printing
the error message in the console.
Coercion will be applied to a value after
all other modifications, such as [`.normalize()`](#normalize).
_Examples:_
```js
var argv = require('yargs')
.coerce('file', function (arg) {
return require('fs').readFileSync(arg, 'utf8')
})
.argv
```
Optionally `.coerce()` can take an object that maps several keys to their
respective coercion function.
```js
var argv = require('yargs')
.coerce({
date: Date.parse,
json: JSON.parse
})
.argv
```
You can also map the same function to several keys at one time. Just pass an
array of keys as the first argument to `.coerce()`:
```js
var path = require('path')
var argv = require('yargs')
.coerce(['src', 'dest'], path.resolve)
.argv
```
If you are using dot-notion or arrays, .e.g., `user.email` and `user.password`,
coercion will be applied to the final object that has been parsed:
```js
// --user.name Batman --user.password 123
// gives us: {name: 'batman', password: '[SECRET]'}
var argv = require('yargs')
.option('user')
.coerce('user', opt => {
opt.name = opt.name.toLowerCase()
opt.password = '[SECRET]'
return opt
})
.argv
```
.command(cmd, desc, [builder], [handler])
-----------------------------------------
.command(cmd, desc, [module])
-----------------------------
.command(module)
----------------
Define the commands exposed by your application.
`cmd` should be a string representing the command or an array of strings
representing the command and its aliases. Read more about command aliases in the
subsection below.
Use `desc` to provide a description for each command your application accepts (the
values stored in `argv._`). Set `desc` to `false` to create a hidden command.
Hidden commands don't show up in the help output and aren't available for
completion.
Optionally, you can provide a `builder` object to give hints about the
options that your command accepts:
```js
yargs
.command('get', 'make a get HTTP request', {
url: {
alias: 'u',
default: 'http://yargs.js.org/'
}
})
.help()
.argv
```
`builder` can also be a function. This function is executed
with a `yargs` instance, and can be used to provide _advanced_ command specific help:
```js
yargs
.command('get', 'make a get HTTP request', function (yargs) {
return yargs.option('url', {
alias: 'u',
default: 'http://yargs.js.org/'
})
})
.help()
.argv
```
You can also provide a handler function, which will be executed with the
parsed `argv` object:
```js
yargs
.command(
'get',
'make a get HTTP request',
function (yargs) {
return yargs.option('u', {
alias: 'url',
describe: 'the URL to make an HTTP request to'
})
},
function (argv) {
console.log(argv.url)
}
)
.help()
.argv
```
Please see [Advanced Topics: Commands](https://github.com/yargs/yargs/blob/master/docs/advanced.md#commands) for a thorough
discussion of the advanced features exposed in the Command API.
.completion([cmd], [description], [fn])
---------------------------------------
Enable bash/zsh-completion shortcuts for commands and options.
`cmd`: When present in `argv._`, will result in the `.bashrc` or `.zshrc` completion script
being outputted. To enable bash/zsh completions, concat the generated script to your
`.bashrc` or `.bash_profile` (or `.zshrc` for zsh).
`description`: Provide a description in your usage instructions for the command
that generates the completion scripts.
`fn`: Rather than relying on yargs' default completion functionality, which
shiver me timbers is pretty awesome, you can provide your own completion
method.
If invoked without parameters, `.completion()` will make `completion` the command to output
the completion script.
```js
var argv = require('yargs')
.completion('completion', function(current, argv) {
// 'current' is the current command being completed.
// 'argv' is the parsed arguments so far.
// simply return an array of completions.
return [
'foo',
'bar'
];
})
.argv;
```
You can also provide asynchronous completions.
```js
var argv = require('yargs')
.completion('completion', function(current, argv, done) {
setTimeout(function() {
done([
'apple',
'banana'
]);
}, 500);
})
.argv;
```
But wait, there's more! You can return an asynchronous promise.
```js
var argv = require('yargs')
.completion('completion', function(current, argv) {
return new Promise(function (resolve, reject) {
setTimeout(function () {
resolve(['apple', 'banana'])
}, 10)
})
})
.argv;
```
.config([key], [description], [parseFn])
-------------------------------------------------------------
.config(object)
---------------
Tells the parser that if the option specified by `key` is passed in, it
should be interpreted as a path to a JSON config file. The file is loaded
and parsed, and its properties are set as arguments. Because the file is
loaded using Node's require(), the filename MUST end in `.json` to be
interpreted correctly.
If invoked without parameters, `.config()` will make `--config` the option to pass the JSON config file.
An optional `description` can be provided to customize the config (`key`) option
in the usage string.
An optional `parseFn` can be used to provide a custom parser. The parsing
function must be synchronous, and should return an object containing
key value pairs or an error.
```js
var argv = require('yargs')
.config('settings', function (configPath) {
return JSON.parse(fs.readFileSync(configPath, 'utf-8'))
})
.argv
```
You can also pass an explicit configuration `object`, it will be parsed
and its properties will be set as arguments.
```js
var argv = require('yargs')
.config({foo: 1, bar: 2})
.argv
console.log(argv)
```
```

foo: 1,
bar: 2,
'$0': 'test.js' }
```
### `extends` Keyword
`config` and `pkgConf` can provide the `extends` keyword to
indicate that configuration should inherit from another location.
The value of extends can be either a relative or absolute path to a JSON
configuration file, e.g.,
```js
yargs.config({
extends: './configs/a.json',
logLevel: 'verbose'
})
```
Or, a module can be provided (this is useful for creating functionality like
[babel-presets](https://babeljs.io/docs/plugins/)).
**my-library.js**
```js
yargs.pkgConf('nyc')
```
**consuming package.json**
```json
{
"nyc": {
"extends": "nyc-babel-config"
}
}
```
Where `nyc-babel-config` is a package that exports configuration in its index.
.conflicts(x, y)
----------------------------------------------
Given the key `x` is set, the key `y` must not be set. `y` can either be a single
string or an array of argument names that `x` conflicts with.
Optionally `.conflicts()` can accept an object specifying multiple conflicting keys.
.count(key)
------------
Interpret `key` as a boolean flag, but set its parsed value to the number of
flag occurrences rather than `true` or `false`. Default value is thus `0`.
.default(key, value, [description])
---------------------------------------------------------
.defaults(key, value, [description])
------------------------------------
**Note:** The `.defaults()` alias is deprecated. It will be
removed in the next major version.
Set `argv[key]` to `value` if no option was specified in `process.argv`.
Optionally `.default()` can take an object that maps keys to default values.
But wait, there's more! The default value can be a `function` which returns
a value. The name of the function will be used in the usage string:
```js
var argv = require('yargs')
.default('random', function randomValue() {
return Math.random() * 256;
}).argv;
```
Optionally, `description` can also be provided and will take precedence over
displaying the value in the usage instructions:
```js
.default('timeout', 60000, '(one-minute)')
```
.demand(count, [max], [msg]) [DEPRECATED]
--------------------
`demand()` has been deprecated, please instead see [`demandOption()`](#demandOption) and
[`demandCommand()`](#demandCommand).
.demandOption(key, [msg | boolean])
------------------------------
.demandOption(key, msg)
------------------------------
If `key` is a string, show the usage information and exit if `key` wasn't
specified in `process.argv`.
If `key` is an array, demand each element.
If a `msg` string is given, it will be printed when the argument is missing, instead of the standard error message.
```javascript
// demand an array of keys to be provided
require('yargs')
.option('run', {
alias: 'r',
describe: 'run your program'
})
.option('path', {
alias: 'p',
describe: 'provide a path to file'
})
.option('spec', {
alias: 's',
describe: 'program specifications'
})
.demandOption(['run', 'path'], 'Please provide both run and path arguments to work with this tool')
.help()
.argv
```
which will provide the following output:
```bash
Options:
--run, -r run your program [required]
--path, -p provide a path to file [required]
--spec, -s program specifications
--help Show help [boolean]
Missing required arguments: run, path
Please provide both run and path arguments to work with this tool
```
If a `boolean` value is given, it controls whether the option is demanded;
this is useful when using `.options()` to specify command line parameters.
```javascript
// demand individual options within the option constructor
require('yargs')
.options({
'run': {
alias: 'r',
describe: 'run your program',
demandOption: true
},
'path': {
alias: 'p',
describe: 'provide a path to file',
demandOption: true
},
'spec': {
alias: 's',
describe: 'program specifications'
}
})
.help()
.argv
```
which will provide the following output:
```bash
Options:
--run, -r run your program [required]
--path, -p provide a path to file [required]
--spec, -s program specifications
--help Show help [boolean]
Missing required arguments: run, path
```
.demandCommand([min=1], [minMsg])
------------------------------
.demandCommand([min=1], [max], [minMsg], [maxMsg])
------------------------------
Demand in context of commands. You can demand a minimum and a maximum number a user can have within your program, as well as provide corresponding error messages if either of the demands is not met.
```javascript
require('yargs')
.command({
command: 'configure [value]',
aliases: ['config', 'cfg'],
desc: 'Set a config variable',
builder: (yargs) => yargs.default('value', 'true'),
handler: (argv) => {
console.log(`setting ${argv.key} to ${argv.value}`)
}
})
// provide a minimum demand and a minimum demand message
.demandCommand(1, 'You need at least one command before moving on')
.help()
.argv
```
which will provide the following output:
```bash
Commands:
configure [value] Set a config variable [aliases: config, cfg]
Options:
--help Show help [boolean]
You need at least one command before moving on
```
_Note: in `minMsg` and `maxMsg`, every occurrence of `$0` will be replaced
with the observed value, and every instance of `$1` will be replaced with the
expected value._
.deprecateOption(key, [msg | boolean])
--------------------
Shows a `[deprecated]` notice in front of the option.
```javascript
require('yargs')
.option('old')
.deprecateOption('old')
.option('new')
```
```bash
Options:
--old [deprecated]
--new
```
You can also specify a message
```javascript
require('yargs')
.option('old')
.deprecateOption('old', 'use --new')
.option('new')
```
```bash
Options:
--old [deprecated: use --new]
--new
```
You can also use it within the option constructor
```javascript
require('yargs')
.option('old', { deprecated: true })
```
.describe(key, desc)
--------------------
Describe a `key` for the generated usage information.
Optionally `.describe()` can take an object that maps keys to descriptions.
.hide(key)
--------------------
Hides a `key` from the generated usage information. Unless a `--show-hidden` option is also passed with `--help` (see [`showHidden()`](#showHidden)).
.detectLocale(boolean)
-----------
Should yargs attempt to detect the os' locale? Defaults to `true`.
.env([prefix])
--------------
Tell yargs to parse environment variables matching the given prefix and apply
them to argv as though they were command line arguments.
Use the "\_\_" separator in the environment variable to indicate nested options.
(e.g. prefix_nested__foo => nested.foo)
If this method is called with no argument or with an empty string or with `true`,
then all env vars will be applied to argv.
Program arguments are defined in this order of precedence:
1. Command line args
2. Env vars
3. Config file/objects
4. Configured defaults
```js
var argv = require('yargs')
.env('MY_PROGRAM')
.option('f', {
alias: 'fruit-thing',
default: 'apple'
})
.argv
console.log(argv)
```
```
$ node fruity.js
{ _: [],
f: 'apple',
'fruit-thing': 'apple',
fruitThing: 'apple',
'$0': 'fruity.js' }
```
```
$ MY_PROGRAM_FRUIT_THING=banana node fruity.js
{ _: [],
fruitThing: 'banana',
f: 'banana',
'fruit-thing': 'banana',
'$0': 'fruity.js' }
```
```
$ MY_PROGRAM_FRUIT_THING=banana node fruity.js -f cat
{ _: [],
f: 'cat',
'fruit-thing': 'cat',
fruitThing: 'cat',
'$0': 'fruity.js' }
```
Env var parsing is disabled by default, but you can also explicitly disable it
by calling `.env(false)`, e.g. if you need to undo previous configuration.
.epilog(str)
------------
.epilogue(str)
--------------
A message to print at the end of the usage instructions, e.g.
```js
var argv = require('yargs')
.epilogue('for more information, find our manual at http://example.com');
```
.example(cmd, desc)
-------------------
Give some example invocations of your program. Inside `cmd`, the string
`$0` will get interpolated to the current script name or node command for the
present script similar to how `$0` works in bash or perl.
Examples will be printed out as part of the help message.
.exitProcess(enable)
----------------------------------
By default, yargs exits the process when the user passes a help flag, the user
uses the `.version` functionality, validation fails, or the command handler
fails. Calling `.exitProcess(false)` disables this behavior, enabling further
actions after yargs have been validated.
***Note:*** `.exitProcess(false)` should not be used when [`.command()`](#command)
is called with a handler returning a promise, as it would lead to a duplicated
error message when this promise rejects
.exit(code, err)
---------
Manually indicate that the program should exit, and provide context about why we
wanted to exit. Follows the behaviour set by `.exitProcess()`.
.fail(fn)
---------
Method to execute when a failure occurs, rather than printing the failure message.
`fn` is called with the failure message that would have been printed, the
`Error` instance originally thrown and yargs state when the failure
occured.
```js
var argv = require('yargs')
.fail(function (msg, err, yargs) {
if (err) throw err // preserve stack
console.error('You broke it!')
console.error(msg)
console.error('You should be doing', yargs.help())
process.exit(1)
})
.argv
```
.getCompletion(args, done);
---------------------------
Allows to programmatically get completion choices for any line.
`args`: An array of the words in the command line to complete.
`done`: The callback to be called with the resulting completions.
For example:
```js
require('yargs')
.option('foobar')
.option('foobaz')
.completion()
.getCompletion(['./test.js', '--foo'], function (completions) {
console.log(completions)
})
```
Outputs the same completion choices as `./test.js --foo`TAB: `--foobar` and `--foobaz`
.global(globals, [global=true])
------------
Indicate that an option (or group of options) should not be reset when a command
is executed, as an example:
```js
var argv = require('yargs')
.option('a', {
alias: 'all',
default: true,
global: false
})
.option('n', {
alias: 'none',
default: true,
global: false
})
.command('foo', 'foo command', function (yargs) {
return yargs.option('b', {
alias: 'bar'
})
})
.help('help')
.global('a')
.argv
```
If the `foo` command is executed the `all` option will remain, but the `none`
option will have been eliminated.
Options default to being global.
.group(key(s), groupName)
--------------------
Given a key, or an array of keys, places options under an alternative heading
when displaying usage instructions, e.g.,
```js
var yargs = require('yargs')(['--help'])
.help()
.group('batman', 'Heroes:')
.describe('batman', "world's greatest detective")
.wrap(null)
.argv
```
***
Heroes:
--batman world's greatest detective
Options:
--help Show help [boolean]
.help()
-----------------------------------------
.help([option | boolean])
-----------------------------------------
.help([option, [description]])
-----------------------------------------
Configure an (e.g. `--help`) and implicit command that displays the usage
string and exits the process. By default yargs enables help on the `--help` option.
If present, the `description` parameter customizes the description of
the help option in the usage string.
If the boolean argument `false` is provided, it will disable `--help`.
Note that any multi-char aliases (e.g. `help`) used for the help option will
also be used for the implicit command. If there are no multi-char aliases (e.g.
`h`), then all single-char aliases will be used for the command.
If invoked without parameters, `.help()` will use `--help` as the option and
`help` as the implicit command to trigger help output.
Example:
```js
var yargs = require("yargs")(['--info'])
.usage("$0 -operand1 number -operand2 number -operation [add|subtract]")
.help('info')
.argv
```
.implies(x, y)
--------------
Given the key `x` is set, it is required that the key `y` is set. `y` can either
be the name of an argument to imply, a number indicating the
position of an argument or an array of multiple implications to associate with `x`.
Optionally `.implies()` can accept an object specifying multiple implications.
.locale()
---------
Return the locale that yargs is currently using.
By default, yargs will auto-detect the operating system's locale so that
yargs-generated help content will display in the user's language.
To override this behavior with a static locale, pass the desired locale as a
string to this method (see below).
.locale(locale)
---------------
Override the auto-detected locale from the user's operating system with a static
locale. Note that the OS locale can be modified by setting/exporting the `LC_ALL`
environment variable.
```js
var argv = require('yargs')
.usage('./$0 - follow ye instructions true')
.option('option', {
alias: 'o',
describe: "'tis a mighty fine option",
demandOption: true
})
.command('run', "Arrr, ya best be knowin' what yer doin'")
.example('$0 run foo', "shiver me timbers, here's an example for ye")
.help('help')
.wrap(70)
.locale('pirate')
.argv
```
***
```shell
./test.js - follow ye instructions true
Choose yer command:
run Arrr, ya best be knowin' what yer doin'
Options for me hearties!
--option, -o 'tis a mighty fine option [requi-yar-ed]
--help Parlay this here code of conduct [boolean]
Ex. marks the spot:
test.js run foo shiver me timbers, here's an example for ye
Ye be havin' to set the followin' argument land lubber: option
```

.middleware(callbacks, [applyBeforeValidation])
------------------------------------
Define global middleware functions to be called first, in list order, for all cli command.
The `callbacks` parameter can be a function or a list of functions. Each callback gets passed a reference to argv.
```js
const mwFunc1 = argv => console.log('I\'m a middleware function');
const mwFunc2 = argv => console.log('I\'m another middleware function');
yargs
.command('myCommand', 'some command', {}, function(argv){
console.log('Running myCommand!');
})
.middleware([mwFunc1, mwFunc2]).argv;
```
When calling `myCommand` from the command line, mwFunc1 gets called first, then mwFunc2, and finally the command's handler. The console output is:
```
I'm a middleware function
I'm another middleware function
Running myCommand!
```
Middleware can be applied before validation by setting the second parameter to `true`. This will execute the middleware prior to validation checks, but after parsing.
Middleware is passed two parameters `argv`, the current parsed options object,
and `yargs` the yargs instance itself, which provides contextual information
about the current state of parsing.
A modified `argv` object will ultimately be what is passed to a command's
handler function.
```js
// populating home directory from an environment variable.
require('yargs')
.middleware(function (argv) {
if (process.env.HOME) argv.home = process.env.HOME
}, true)
.command('configure-home', "do something with a user's home directory",
{
'home': {
'demand': true,
'string': true
}
},
function(argv) {
console.info(`we know the user's home directory is ${argv.home}`)
}
)
.parse()
```
.nargs(key, count)
-----------
The number of arguments that should be consumed after a key. This can be a
useful hint to prevent parsing ambiguity. For example:
```js
var argv = require('yargs')
.nargs('token', 1)
.parse(['--token', '-my-token']);
```
parses as:
`{ _: [], token: '-my-token', '$0': 'node test' }`
Optionally `.nargs()` can take an object of `key`/`narg` pairs.
.normalize(key)
---------------
The key provided represents a path and should have `path.normalize()` applied.
.number(key)
------------
Tell the parser to always interpret `key` as a number.
If `key` is an array, all elements will be parsed as numbers.
If the option is given on the command line without a value, `argv` will be
populated with `undefined`.
If the value given on the command line cannot be parsed as a number, `argv` will
be populated with `NaN`.
Note that decimals, hexadecimals, and scientific notation are all accepted.
```js
var argv = require('yargs')
.number('n')
.number(['width', 'height'])
.argv
```
.option(key, [opt])
-----------------
.options(key, [opt])
------------------
This method can be used to make yargs aware of options that _could_
exist. You can also pass an `opt` object which can hold further
customization, like `.alias()`, `.demandOption()` etc. for that option.
For example:
````javascript
var argv = require('yargs')
.option('f', {
alias: 'file',
demandOption: true,
default: '/etc/passwd',
describe: 'x marks the spot',
type: 'string'
})
.argv
;
````
is the same as
````javascript
var argv = require('yargs')
.alias('f', 'file')
.demandOption('f')
.default('f', '/etc/passwd')
.describe('f', 'x marks the spot')
.string('f')
.argv
;
````
Optionally `.options()` can take an object that maps keys to `opt` parameters.
````javascript
var argv = require('yargs')
.options({
'f': {
alias: 'file',
demandOption: true,
default: '/etc/passwd',
describe: 'x marks the spot',
type: 'string'
}
})
.argv
;
````
Valid `opt` keys include:
- `alias`: string or array of strings, alias(es) for the canonical option key, see [`alias()`](#alias)
- `array`: boolean, interpret option as an array, see [`array()`](#array)
- `boolean`: boolean, interpret option as a boolean flag, see [`boolean()`](#boolean)
- `choices`: value or array of values, limit valid option arguments to a predefined set, see [`choices()`](#choices)
- `coerce`: function, coerce or transform parsed command line values into another value, see [`coerce()`](#coerce)
- `config`: boolean, interpret option as a path to a JSON config file, see [`config()`](#config)
- `configParser`: function, provide a custom config parsing function, see [`config()`](#config)
- `conflicts`: string or array of strings, require certain keys not to be set, see [`conflicts()`](#conflicts)
- `count`: boolean, interpret option as a count of boolean flags, see [`count()`](#count)
- `default`: value, set a default value for the option, see [`default()`](#default)
- `defaultDescription`: string, use this description for the default value in help content, see [`default()`](#default)
- `demandOption`: boolean or string, demand the option be given, with optional error message, see [`demandOption()`](#demandOption)
- `desc`/`describe`/`description`: string, the option description for help content, see [`describe()`](#describe)
- `global`: boolean, indicate that this key should not be [reset](#reset) when a command is invoked, see [`global()`](#global)
- `group`: string, when displaying usage instructions place the option under an alternative group heading, see [`group()`](#group)
- `hidden`: don't display option in help output.
- `implies`: string or array of strings, require certain keys to be set, see [`implies()`](#implies)
- `nargs`: number, specify how many arguments should be consumed for the option, see [`nargs()`](#nargs)
- `normalize`: boolean, apply `path.normalize()` to the option, see [`normalize()`](#normalize)
- `number`: boolean, interpret option as a number, [`number()`](#number)
- `requiresArg`: boolean, require the option be specified with a value, see [`requiresArg()`](#requiresArg)
- `skipValidation`: boolean, skips validation if the option is present, see [`skipValidation()`](#skipValidation)
- `string`: boolean, interpret option as a string, see [`string()`](#string)
- `type`: one of the following strings
- `'array'`: synonymous for `array: true`, see [`array()`](#array)
- `'boolean'`: synonymous for `boolean: true`, see [`boolean()`](#boolean)
- `'count'`: synonymous for `count: true`, see [`count()`](#count)
- `'number'`: synonymous for `number: true`, see [`number()`](#number)
- `'string'`: synonymous for `string: true`, see [`string()`](#string)
.parse([args], [context], [parseCallback])
------------
Parse `args` instead of `process.argv`. Returns the `argv` object.
`args` may either be a pre-processed argv array, or a raw argument string.
A `context` object can optionally be given as the second argument to `parse()`, providing a
useful mechanism for passing state information to commands:
```js
const parser = yargs
.command('lunch-train ', 'start lunch train', function () {}, function (argv) {
console.log(argv.restaurant, argv.time)
})
.parse("lunch-train rudy's", {time: '12:15'})
```
A `parseCallback` can also be provided to `.parse()`. If a callback is given, it will be invoked with three arguments:
1. `err`: populated if any validation errors raised while parsing.
2. `argv`: the parsed argv object.
3. `output`: any text that would have been output by yargs to the terminal, had a
callback not been provided.
```js
// providing the `fn` argument to `parse()` runs yargs in headless mode, this
// makes it easy to use yargs in contexts other than the CLI, e.g., writing
// a chat-bot.
const parser = yargs
.command('lunch-train
* bash-completion shortcuts for commands and options.
* and [tons more](/docs/api.md).

### BREAKING CHANGES
* fail is now applied globally.
* we now default to an empty builder function when command is executed with no builder.
* yargs-parser now better handles negative integer values, at the cost of handling numeric option names, e.g., -1 hello
* default: removed undocumented `defaults` alias for `default`.
* introduces a default `help` command which outputs help, as an alternative to a help flag.
* interpret demand() numbers as relative to executing command ([#582](https://github.com/yargs/yargs/issues/582)) ([927810c](https://github.com/yargs/yargs/commit/927810c))

## Commands
Yargs provides a powerful set of tools for composing modular command-driven-applications.
In this section we cover some of the advanced features available in this API:
### Default Commands
To specify a default command use the string `*` or `$0`. A default command
will be run if the positional arguments provided match no known
commands. tldr; default commands allow you to define the entry point to your
application using a similar API to subcommands.
```js
const argv = require('yargs')
.command('$0', 'the default command', () => {}, (argv) => {
console.log('this command will be run by default')
})
.argv
```
The command defined above will be executed if the program
is run with `./my-cli.js --x=22`.
Default commands can also be used as a command alias, like so:
```js
const argv = require('yargs')
.command(['serve', '$0'], 'the serve command', () => {}, (argv) => {
console.log('this command will be run by default')
})
.argv
```
The command defined above will be executed if the program
is run with `./my-cli.js --x=22`, or with `./my-cli.js serve --x=22`.
### Positional Arguments
Commands can accept _optional_ and _required_ positional arguments. Required
positional arguments take the form `
