1# Optionator2<a name="optionator" />3 4Optionator is a JavaScript/Node.js option parsing and help generation library used by [eslint](http://eslint.org), [Grasp](http://graspjs.com), [LiveScript](http://livescript.net), [esmangle](https://github.com/estools/esmangle), [escodegen](https://github.com/estools/escodegen), and [many more](https://www.npmjs.com/browse/depended/optionator).5 6For an online demo, check out the [Grasp online demo](http://www.graspjs.com/#demo).7 8[About](#about) &middot; [Usage](#usage) &middot; [Settings Format](#settings-format) &middot; [Argument Format](#argument-format)9 10## Why?11The  problem with other option parsers, such as `yargs` or `minimist`, is they just accept all input, valid or not.12With Optionator, if you mistype an option, it will give you an error (with a suggestion for what you meant).13If you give the wrong type of argument for an option, it will give you an error rather than supplying the wrong input to your application.14 15    $ cmd --halp16    Invalid option '--halp' - perhaps you meant '--help'?17 18    $ cmd --count str19    Invalid value for option 'count' - expected type Int, received value: str.20 21Other helpful features include reformatting the help text based on the size of the console, so that it fits even if the console is narrow, and accepting not just an array (eg. process.argv), but a string or object as well, making things like testing much easier.22 23## About24Optionator uses [type-check](https://github.com/gkz/type-check) and [levn](https://github.com/gkz/levn) behind the scenes to cast and verify input according the specified types.25 26MIT license. Version 0.9.427 28    npm install optionator29 30For updates on Optionator, [follow me on twitter](https://twitter.com/gkzahariev).31 32Optionator is a Node.js module, but can be used in the browser as well if packed with webpack/browserify.33 34## Usage35`require('optionator');` returns a function. It has one property, `VERSION`, the current version of the library as a string. This function is called with an object specifying your options and other information, see the [settings format section](#settings-format). This in turn returns an object with three properties, `parse`, `parseArgv`, `generateHelp`, and `generateHelpForOption`, which are all functions.36 37```js38var optionator = require('optionator')({39    prepend: 'Usage: cmd [options]',40    append: 'Version 1.0.0',41    options: [{42        option: 'help',43        alias: 'h',44        type: 'Boolean',45        description: 'displays help'46    }, {47        option: 'count',48        alias: 'c',49        type: 'Int',50        description: 'number of things',51        example: 'cmd --count 2'52    }]53});54 55var options = optionator.parseArgv(process.argv);56if (options.help) {57    console.log(optionator.generateHelp());58}59...60```61 62### parse(input, parseOptions)63`parse` processes the `input` according to your settings, and returns an object with the results.64 65##### arguments66* input - `[String] | Object | String` - the input you wish to parse67* parseOptions - `{slice: Int}` - all options optional68    - `slice` specifies how much to slice away from the beginning if the input is an array or string - by default `0` for string, `2` for array (works with `process.argv`)69 70##### returns71`Object` - the parsed options, each key is a camelCase version of the option name (specified in dash-case), and each value is the processed value for that option. Positional values are in an array under the `_` key.72 73##### example74```js75parse(['node', 't.js', '--count', '2', 'positional']); // {count: 2, _: ['positional']}76parse('--count 2 positional');                         // {count: 2, _: ['positional']}77parse({count: 2, _:['positional']});                   // {count: 2, _: ['positional']}78```79 80### parseArgv(input)81`parseArgv` works exactly like `parse`, but only for array input and it slices off the first two elements.82 83##### arguments84* input - `[String]` - the input you wish to parse85 86##### returns87See "returns" section in "parse"88 89##### example90```js91parseArgv(process.argv);92```93 94### generateHelp(helpOptions)95`generateHelp` produces help text based on your settings.96 97##### arguments98* helpOptions - `{showHidden: Boolean, interpolate: Object}` - all options optional99    - `showHidden` specifies whether to show options with `hidden: true` specified, by default it is `false`100    - `interpolate` specify data to be interpolated in `prepend` and `append` text, `{{key}}` is the format - eg. `generateHelp({interpolate:{version: '0.4.2'}})`, will change this `append` text: `Version {{version}}` to `Version 0.4.2`101 102##### returns103`String` - the generated help text104 105##### example106```js107generateHelp(); /*108"Usage: cmd [options] positional109 110  -h, --help       displays help111  -c, --count Int  number of things112 113Version  1.0.0114"*/115```116 117### generateHelpForOption(optionName)118`generateHelpForOption` produces expanded help text for the specified with `optionName` option. If an `example` was specified for the option, it will be displayed,  and if a `longDescription` was specified, it will display that instead of the `description`.119 120##### arguments121* optionName - `String` - the name of the option to display122 123##### returns124`String` - the generated help text for the option125 126##### example127```js128generateHelpForOption('count'); /*129"-c, --count Int130description: number of things131example: cmd --count 2132"*/133```134 135## Settings Format136When your `require('optionator')`, you get a function that takes in a settings object. This object has the type:137 138    {139      prepend: String,140      append: String,141      options: [{heading: String} | {142        option: String,143        alias: [String] | String,144        type: String,145        enum: [String],146        default: String,147        restPositional: Boolean,148        required: Boolean,149        overrideRequired: Boolean,150        dependsOn: [String] | String,151        concatRepeatedArrays: Boolean | (Boolean, Object),152        mergeRepeatedObjects: Boolean,153        description: String,154        longDescription: String,155        example: [String] | String156      }],157      helpStyle: {158        aliasSeparator: String,159        typeSeparator: String,160        descriptionSeparator: String,161        initialIndent: Int,162        secondaryIndent: Int,163        maxPadFactor: Number164      },165      mutuallyExclusive: [[String | [String]]],166      concatRepeatedArrays: Boolean | (Boolean, Object), // deprecated, set in defaults object167      mergeRepeatedObjects: Boolean, // deprecated, set in defaults object168      positionalAnywhere: Boolean,169      typeAliases: Object,170      defaults: Object171    }172 173All of the properties are optional (the `Maybe` has been excluded for brevities sake), except for having either `heading: String` or `option: String` in each object in the `options` array.174 175### Top Level Properties176* `prepend` is an optional string to be placed before the options in the help text177* `append` is an optional string to be placed after the options in the help text178* `options` is a required array specifying your options and headings, the options and headings will be displayed in the order specified179* `helpStyle` is an optional object which enables you to change the default appearance of some aspects of the help text180* `mutuallyExclusive` is an optional array of arrays of either strings or arrays of strings. The top level array is a list of rules, each rule is a list of elements - each element can be either a string (the name of an option), or a list of strings (a group of option names) - there will be an error if more than one element is present181* `concatRepeatedArrays` see description under the "Option Properties" heading - use at the top level is deprecated, if you want to set this for all options, use the `defaults` property182* `mergeRepeatedObjects` see description under the "Option Properties" heading - use at the top level is deprecated, if you want to set this for all options, use the `defaults` property183* `positionalAnywhere` is an optional boolean (defaults to `true`) - when `true` it allows positional arguments anywhere, when `false`, all arguments after the first positional one are taken to be positional as well, even if they look like a flag. For example, with `positionalAnywhere: false`, the arguments `--flag --boom 12 --crack` would have two positional arguments: `12` and `--crack`184* `typeAliases` is an optional object, it allows you to set aliases for types, eg. `{Path: 'String'}` would allow you to use the type `Path` as an alias for the type `String`185* `defaults` is an optional object following the option properties format, which specifies default values for all options. A default will be overridden if manually set. For example, you can do `default: { type: "String" }` to set the default type of all options to `String`, and then override that default in an individual option by setting the `type` property186 187#### Heading Properties188* `heading` a required string, the name of the heading189 190#### Option Properties191* `option` the required name of the option - use dash-case, without the leading dashes192* `alias` is an optional string or array of strings which specify any aliases for the option193* `type` is a required string in the [type check](https://github.com/gkz/type-check) [format](https://github.com/gkz/type-check#type-format), this will be used to cast the inputted value and validate it194* `enum` is an optional array of strings, each string will be parsed by [levn](https://github.com/gkz/levn) - the argument value must be one of the resulting values - each potential value must validate against the specified `type`195* `default` is a optional string, which will be parsed by [levn](https://github.com/gkz/levn) and used as the default value if none is set - the value must validate against the specified `type`196* `restPositional` is an optional boolean - if set to `true`, everything after the option will be taken to be a positional argument, even if it looks like a named argument197* `required` is an optional boolean - if set to `true`, the option parsing will fail if the option is not defined198* `overrideRequired` is a optional boolean - if set to `true` and the option is used, and there is another option which is required but not set, it will override the need for the required option and there will be no error - this is useful if you have required options and want to use `--help` or `--version` flags199* `concatRepeatedArrays` is an optional boolean or tuple with boolean and options object (defaults to `false`) - when set to `true` and an option contains an array value and is repeated, the subsequent values for the flag will be appended rather than overwriting the original value - eg. option `g` of type `[String]`: `-g a -g b -g c,d` will result in `['a','b','c','d']`200 201 You can supply an options object by giving the following value: `[true, options]`. The one currently supported option is `oneValuePerFlag`, this only allows one array value per flag. This is useful if your potential values contain a comma.202* `mergeRepeatedObjects` is an optional boolean (defaults to `false`) - when set to `true` and an option contains an object value and is repeated, the subsequent values for the flag will be merged rather than overwriting the original value - eg. option `g` of type `Object`: `-g a:1 -g b:2 -g c:3,d:4` will result in `{a: 1, b: 2, c: 3, d: 4}`203* `dependsOn` is an optional string or array of strings - if simply a string (the name of another option), it will make sure that that other option is set, if an array of strings, depending on whether `'and'` or `'or'` is first, it will either check whether all (`['and', 'option-a', 'option-b']`), or at least one (`['or', 'option-a', 'option-b']`) other options are set204* `description` is an optional string, which will be displayed next to the option in the help text205* `longDescription` is an optional string, it will be displayed instead of the `description` when `generateHelpForOption` is used206* `example` is an optional string or array of strings with example(s) for the option - these will be displayed when `generateHelpForOption` is used207 208#### Help Style Properties209* `aliasSeparator` is an optional string, separates multiple names from each other - default: ' ,'210* `typeSeparator` is an optional string, separates the type from the names - default: ' '211* `descriptionSeparator` is an optional string , separates the description from the padded name and type - default: '  '212* `initialIndent` is an optional int - the amount of indent for options - default: 2213* `secondaryIndent` is an optional int - the amount of indent if wrapped fully (in addition to the initial indent) - default: 4214* `maxPadFactor` is an optional number - affects the default level of padding for the names/type, it is multiplied by the average of the length of the names/type - default: 1.5215 216## Argument Format217At the highest level there are two types of arguments: named, and positional.218 219Name arguments of any length are prefixed with `--` (eg. `--go`), and those of one character may be prefixed with either `--` or `-` (eg. `-g`).220 221There are two types of named arguments: boolean flags (eg. `--problemo`, `-p`) which take no value and result in a `true` if they are present, the falsey `undefined` if they are not present, or `false` if present and explicitly prefixed with `no` (eg. `--no-problemo`). Named arguments with values (eg. `--tseries 800`, `-t 800`) are the other type. If the option has a type `Boolean` it will automatically be made into a boolean flag. Any other type results in a named argument that takes a value.222 223For more information about how to properly set types to get the value you want, take a look at the [type check](https://github.com/gkz/type-check) and [levn](https://github.com/gkz/levn) pages.224 225You can group single character arguments that use a single `-`, however all except the last must be boolean flags (which take no value). The last may be a boolean flag, or an argument which takes a value - eg. `-ba 2` is equivalent to `-b -a 2`.226 227Positional arguments are all those values which do not fall under the above - they can be anywhere, not just at the end. For example, in `cmd -b one -a 2 two` where `b` is a boolean flag, and `a` has the type `Number`, there are two positional arguments, `one` and `two`.228 229Everything after an `--` is positional, even if it looks like a named argument.230 231You may optionally use `=` to separate option names from values, for example: `--count=2`.232 233If you specify the option `NUM`, then any argument using a single `-` followed by a number will be valid and will set the value of `NUM`. Eg. `-2` will be parsed into `NUM: 2`.234 235If duplicate named arguments are present, the last one will be taken.236 237## Technical About238`optionator` is written in [LiveScript](http://livescript.net/) - a language that compiles to JavaScript. It uses [levn](https://github.com/gkz/levn) to cast arguments to their specified type, and uses [type-check](https://github.com/gkz/type-check) to validate values. It also uses the [prelude.ls](http://preludels.com/) library.239
