|

Define argument flags.
|

|

The key is the flag name and the value is an object with any of:
|
||||
|
||||
- `type`: Type of value. (Possible values: `string` `boolean` `number`)
|
||||
- `alias`: Usually used to define a short flag alias.
|
||||
- `default`: Default value when the flag is not specified.
|
||||
- `isRequired`: Determine if the flag is required.
|
||||
If it's only known at runtime whether the flag is required or not you can pass a Function instead of a boolean, which based on the given flags and other non-flag arguments should decide if the flag is required.
|
||||
- `isMultiple`: Indicates a flag can be set multiple times. Values are turned into an array. (Default: false)
|
||||
Multiple values are provided by specifying the flag multiple times, for example, `$ foo -u rainbow -u cat`. Space- or comma-separated values are *not* supported.
|
||||
|
||||
@example
|
||||
```
|
||||
flags: {

||||
unicorn: {
|
||||
type: 'string',
|

alias: 'u',

## API
|
||||
|
||||
### meow(helpText, options?)
|
||||
### meow(options)
|
||||
|
||||
Returns an `object` with:
|
||||
|
||||
- `input` *(Array)* - Non-flag arguments
|
||||
- `flags` *(Object)* - Flags converted to camelCase excluding aliases
|
||||
- `unnormalizedFlags` *(Object)* - Flags converted to camelCase including aliases
|
||||
- `pkg` *(Object)* - The `package.json` object
|
||||
- `help` *(string)* - The help text used with `--help`
|
||||
- `showHelp([exitCode=2])` *(Function)* - Show the help text and exit with `exitCode`
|
||||
- `showVersion()` *(Function)* - Show the version text and exit
|
||||
|
||||
#### helpText
|
||||
|
||||
Type: `string`
|
||||
|
||||
Shortcut for the `help` option.
|
||||
|
||||
#### options
|
||||
|
||||
Type: `object`
|
||||
|
||||
##### flags
|
||||
|
||||
Type: `object`
|
||||
|
||||
Define argument flags.
|
||||
|
||||
The key is the flag name and the value is an object with any of:
|
||||
|
||||
- `type`: Type of value. (Possible values: `string` `boolean` `number`)
|
||||
- `alias`: Usually used to define a short flag alias.
|
||||
- `default`: Default value when the flag is not specified.
|
||||
- `isRequired`: Determine if the flag is required. (Default: false)
|
||||
- If it's only known at runtime whether the flag is required or not, you can pass a `Function` instead of a `boolean`, which based on the given flags and other non-flag arguments, should decide if the flag is required. Two arguments are passed to the function:
|
||||
- The first argument is the **flags** object, which contains the flags converted to camel-case excluding aliases.
|
||||
- The second argument is the **input** string array, which contains the non-flag arguments.
|
||||
- The function should return a `boolean`, true if the flag is required, otherwise false.
|
||||
- `isMultiple`: Indicates a flag can be set multiple times. Values are turned into an array. (Default: false)
|
||||
- Multiple values are provided by specifying the flag multiple times, for example, `$ foo -u rainbow -u cat`. Space- or comma-separated values are [currently *not* supported](https://github.com/sindresorhus/meow/issues/164).
|
||||
|
||||
Example:
|
||||
|
||||
```js
|
||||
flags: {
|
||||
unicorn: {
|
||||
type: 'string',
|
||||
alias: 'u',
|
||||
default: ['rainbow', 'cat'],
|
||||
isMultiple: true,
|
||||
isRequired: (flags, input) => {
|
||||
if (flags.otherFlag) {
|
||||
return true;
|
||||
}
|
||||
|
||||
return false;
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
##### description
|
||||
|
||||
Type: `string | boolean`\
|
||||
Default: The package.json `"description"` property
|
||||
|
||||
Description to show above the help text.
|
||||
|
||||
Set it to `false` to disable it altogether.
|
||||
|
||||
##### help
|
||||
|
||||
Type: `string | boolean`
|
||||
|
||||
The help text you want shown.
|
||||
|
||||
The input is reindented and starting/ending newlines are trimmed which means you can use a [template literal](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/template_strings) without having to care about using the correct amount of indent.
|
||||
|
||||
The description will be shown above your help text automatically.
|
||||
|
||||
##### version
|
||||
|
||||
Type: `string | boolean`\
|
||||
Default: The package.json `"version"` property
|
||||
|
||||
Set a custom version output.
|
||||
|
||||
##### autoHelp
|
||||
|
||||
Type: `boolean`\
|
||||
Default: `true`
|
||||
|
||||
Automatically show the help text when the `--help` flag is present. Useful to set this value to `false` when a CLI manages child CLIs with their own help text.
|
||||
|
||||
This option is only considered when there is only one argument in `process.argv`.
|
||||
|
||||
##### autoVersion
|
||||
|
||||
Type: `boolean`\
|
||||
Default: `true`
|
||||
|
||||
Automatically show the version text when the `--version` flag is present. Useful to set this value to `false` when a CLI manages child CLIs with their own version text.
|
||||
|
||||
This option is only considered when there is only one argument in `process.argv`.
|
||||
|
||||
##### pkg
|
||||
|
||||
Type: `object`\
|
||||
Default: Closest package.json upwards
|
||||
|
||||
package.json as an `object`.
|
||||
|
||||
*You most likely don't need this option.*
|
||||
|
||||
##### argv
|
||||
|
||||
Type: `string[]`\
|
||||
Default: `process.argv.slice(2)`
|
||||
|
||||
Custom arguments object.
|
||||
|
||||
##### inferType
|
||||
|
||||
Type: `boolean`\
|
||||
Default: `false`
|
||||
|
||||
Infer the argument type.
|
||||
|
||||
By default, the argument `5` in `$ foo 5` becomes a string. Enabling this would infer it as a number.
|
||||
|
||||
##### booleanDefault
|
||||
|
||||
Type: `boolean | null | undefined`\
|
||||
Default: `false`
|
||||
|
||||
Value of `boolean` flags not defined in `argv`.
|
||||
|
||||
If set to `undefined`, the flags not defined in `argv` will be excluded from the result.
|
||||
The `default` value set in `boolean` flags take precedence over `booleanDefault`.
|
||||
|
||||
_Note: If used in conjunction with `isMultiple`, the default flag value is set to `[]`._
|
||||
|
||||
__Caution: Explicitly specifying `undefined` for `booleanDefault` has different meaning from omitting key itself.__
|
||||
|
||||
Example:
|
||||
|
||||
```js
|
||||
const meow = require('meow');
|
||||
|
||||
const cli = meow(`
|
||||
Usage
|
||||
$ foo
|
||||
|
||||
Options
|
||||
--rainbow, -r Include a rainbow
|
||||
--unicorn, -u Include a unicorn
|
||||
--no-sparkles Exclude sparkles
|
||||
|
||||
Examples
|
||||
$ foo
|
||||
🌈 unicorns✨🌈
|
||||
`, {
|
||||
booleanDefault: undefined,
|
||||
flags: {
|
||||
rainbow: {
|
||||
type: 'boolean',
|
||||
default: true,
|
||||
alias: 'r'
|
||||
},
|
||||
unicorn: {
|
||||
type: 'boolean',
|
||||
default: false,
|
||||
alias: 'u'
|
||||
},
|
||||
cake: {
|
||||
type: 'boolean',
|
||||
alias: 'c'
|
||||
},
|
||||
sparkles: {
|
||||
type: 'boolean',
|
||||
default: true
|
||||
}
|
||||
}
|
||||
});
|
||||
/*
|
||||
{
|
||||
flags: {
|
||||
rainbow: true,
|
||||
unicorn: false,
|
||||
sparkles: true
|
||||
},
|
||||
unnormalizedFlags: {
|
||||
rainbow: true,
|
||||
r: true,
|
||||
unicorn: false,
|
||||
u: false,
|
||||
sparkles: true
|
||||
},
|
||||
…
|
||||
}
|
||||
*/
|
||||
```
|
||||
|
||||
##### hardRejection
|
||||
|
||||
Type: `boolean`\
|
||||
Default: `true`
|
||||
|
||||
Whether to use [`hard-rejection`](https://github.com/sindresorhus/hard-rejection) or not. Disabling this can be useful if you need to handle `process.on('unhandledRejection')` yourself.
|
||||
|
||||
#### allowUnknownFlags
|
||||
|
||||
Type `boolean`\
|
||||
Default: `true`
|
||||
|
||||
Whether to allow unknown flags or not.
|
||||
|
||||
## Promises
|
||||
|
||||
Meow will make unhandled rejected promises [fail hard](https://github.com/sindresorhus/hard-rejection) instead of the default silent fail. Meaning you don't have to manually `.catch()` promises used in your CLI.
|
||||
|
||||
## Tips
|
||||
|
||||
See [`chalk`](https://github.com/chalk/chalk) if you want to colorize the terminal output.
|
||||
|
||||
See [`get-stdin`](https://github.com/sindresorhus/get-stdin) if you want to accept input from stdin.
|
||||
|
||||
See [`conf`](https://github.com/sindresorhus/conf) if you need to persist some data.
|
||||
|
||||
See [`update-notifier`](https://github.com/yeoman/update-notifier) if you want update notifications.
