This is a relatively simple parsing operation, and regex is the slowest and most error-prone way to do it. +* Have no problem reading YAML files directly +* Have no problem with complex content, including **non-front-matter** fenced code blocks that contain examples of YAML front matter. Other parsers fail on this. +* Support stringifying back to front-matter. This is useful for linting, updating properties, etc. +* Allow custom delimiters, when it's necessary for avoiding delimiter collision. +* Should return an object with at least these three properties: + - `data`: the parsed YAML front matter, as a JSON object + - `content`: the contents as a string, without the front matter + - `orig`: the "original" content (for debugging) + +</details> + +## Usage + +Using Node's `require()` system: + +```js +const matter = require('gray-matter'); +``` + +Or with [typescript](https://www.typescriptlang.org) + +```js +import matter = require('gray-matter'); +// OR +import * as matter from 'gray-matter'; +``` + +Pass a string and [options](#options) to gray-matter: + +```js +console.log(matter('---\ntitle: Front Matter\n---\nThis is content.')); +``` + +Returns: + +```js +{ + content: '\nThis is content.', + data: { + title: 'Front Matter' + } +} +``` + +More about the returned object in the following section. + +*** + +## Returned object + +gray-matter returns a `file` object with the following properties. + +**Enumerable** + +* `file.data` **{Object}**: the object created by parsing front-matter +* `file.content` **{String}**: the input string, with `matter` stripped +* `file.excerpt` **{String}**: an excerpt, if [defined on the options](#optionsexcerpt) +* `file.empty` **{String}**: when the front-matter is "empty" (either all whitespace, nothing at all, or just comments and no data), the original string is set on this property.

The 'appendConst' action is typically used when multiple arguments need + to store constants to the same list. +- ```count``` - Counts the number of times a keyword argument occurs. For example, + used for increasing verbosity levels. +- ```help``` - Prints a complete help message for all the options in the current + parser and then exits. By default a help action is automatically added to the parser. + See ArgumentParser for details of how the output is created. +- ```version``` - Prints version information and exit.

Splitting up functionality this way can be a particularly good +idea when a program performs several different functions which require different +kinds of command-line arguments. `ArgumentParser` supports creation of such +sub-commands with `addSubparsers()` method. The `addSubparsers()` method is +normally called with no arguments and returns an special action object. +This object has a single method `addParser()`, which takes a command name and +any `ArgumentParser` constructor arguments, and returns an `ArgumentParser` object +that can be modified as usual. + +Example: + +sub_commands.js +```javascript +#!/usr/bin/env node +'use strict'; + +var ArgumentParser = require('../lib/argparse').ArgumentParser; +var parser = new ArgumentParser({ + version: '0.0.1', + addHelp:true, + description: 'Argparse examples: sub-commands', +}); + +var subparsers = parser.addSubparsers({ + title:'subcommands', + dest:"subcommand_name" +}); + +var bar = subparsers.addParser('c1', {addHelp:true}); +bar.addArgument( + [ '-f', '--foo' ], + { + action: 'store', + help: 'foo3 bar3' + } +); +var bar = subparsers.addParser( + 'c2', + {aliases:['co'], addHelp:true} +); +bar.addArgument( + [ '-b', '--bar' ], + { + action: 'store', + type: 'int', + help: 'foo3 bar3' + } +); + +var args = parser.parseArgs(); +console.dir(args); + +``` + +Details in [original sub-commands guide](http://docs.python.org/dev/library/argparse.html#sub-commands) + + +Contributors +============ + +- [Eugene Shkuropat](https://github.com/shkuropat) +- [Paul Jacobson](https://github.com/hpaulj) + +[others](https://github.com/nodeca/argparse/graphs/contributors) + +License +======= + +Copyright (c) 2012 [Vitaly Puzrin](https://github.com/puzrin). +Released under the MIT license.

Don't expect fast fixes if something goes wrong there. +2. `!!js/function` in browser bundle will not work by default.

Returns either a +plain object, a string or `undefined`, or throws `YAMLException` on error. By default, does +not support regexps, functions and undefined. This method is safe for untrusted data. + +options: + +- `filename` _(default: null)_ - string to be used as a file path in + error/warning messages. +- `onWarning` _(default: null)_ - function to call on warning messages. + Loader will call this function with an instance of `YAMLException` for each warning. +- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ - specifies a schema to use. + - `FAILSAFE_SCHEMA` - only strings, arrays and plain objects: + http://www.yaml.org/spec/1.2/spec.html#id2802346 + - `JSON_SCHEMA` - all JSON-supported types: + http://www.yaml.org/spec/1.2/spec.html#id2803231 + - `CORE_SCHEMA` - same as `JSON_SCHEMA`: + http://www.yaml.org/spec/1.2/spec.html#id2804923 + - `DEFAULT_SAFE_SCHEMA` - all supported YAML types, without unsafe ones + (`!!js/undefined`, `!!js/regexp` and `!!js/function`): + http://yaml.org/type/ + - `DEFAULT_FULL_SCHEMA` - all supported YAML types. +- `json` _(default: false)_ - compatibility with JSON.parse behaviour. If true, then duplicate keys in a mapping will override values rather than throwing an error. + +NOTE: This function **does not** understand multi-document sources, it throws +exception on those. + +NOTE: JS-YAML **does not** support schema-specific tag resolution restrictions. +So, the JSON schema is not as strictly defined in the YAML specification. +It allows numbers in any notation, use `Null` and `NULL` as `null`, etc. +The core schema also has no such restrictions. It allows binary notation for integers. + + +### load (string [ , options ]) + +**Use with care with untrusted sources**. The same as `safeLoad()` but uses +`DEFAULT_FULL_SCHEMA` by default - adds some JavaScript-specific types: +`!!js/function`, `!!js/regexp` and `!!js/undefined`. For untrusted sources, you +must additionally validate object structure to avoid injections: + +``` javascript +const untrusted_code = '"toString": !<tag:yaml.org,2002:js/function> "function (){very_evil_thing();}"'; + +// I'm just converting that string, what could possibly go wrong? +require('js-yaml').load(untrusted_code) + '' +``` + + +### safeLoadAll (string [, iterator] [, options ]) + +Same as `safeLoad()`, but understands multi-document sources. Applies +`iterator` to each document if specified, or returns array of documents. + +``` javascript +const yaml = require('js-yaml'); + +yaml.safeLoadAll(data, function (doc) { + console.log(doc); +}); +``` + + +### loadAll (string [, iterator] [ , options ]) + +Same as `safeLoadAll()` but uses `DEFAULT_FULL_SCHEMA` by default. + + +### safeDump (object [ , options ]) + +Serializes `object` as a YAML document. Uses `DEFAULT_SAFE_SCHEMA`, so it will +throw an exception if you try to dump regexps or functions. However, you can +disable exceptions by setting the `skipInvalid` option to `true`. + +options: + +- `indent` _(default: 2)_ - indentation width to use (in spaces). +- `noArrayIndent` _(default: false)_ - when true, will not add an indentation level to array elements +- `skipInvalid` _(default: false)_ - do not throw on invalid types (like function + in the safe schema) and skip pairs and single values with such types. +- `flowLevel` (default: -1) - specifies level of nesting, when to switch from + block to flow style for collections. -1 means block style everwhere +- `styles` - "tag" => "style" map. Each tag may have own set of styles. +- `schema` _(default: `DEFAULT_SAFE_SCHEMA`)_ specifies a schema to use. +- `sortKeys` _(default: `false`)_ - if `true`, sort keys when dumping YAML. If a + function, use the function to sort the keys. +- `lineWidth` _(default: `80`)_ - set max line width. +- `noRefs` _(default: `false`)_ - if `true`, don't convert duplicate objects into references +- `noCompatMode` _(default: `false`)_ - if `true` don't try to be compatible with older + yaml versions. Currently: don't quote "yes", "no" and so on, as required for YAML 1.1 +- `condenseFlow` _(default: `false`)_ - if `true` flow sequences will be condensed, omitting the space between `a, b`. Eg. `'[a,b]'`, and omitting the space between `key: value` and quoting the key. Eg. `'{"a":b}'` Can be useful when using yaml for pretty URL query params as spaces are %-encoded. + +The following table show availlable styles (e.g. "canonical", +"binary"...) available for each tag (.e.g. !!null, !!int ...).
