Returns a JavaScript +object 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 throw on warnings if this function is not provided. +- `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 +var 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 and applies +`iterator` to each document. + +``` javascript +var 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). +- `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 + +The following table show availlable styles (e.g. "canonical", +"binary"...) available for each tag (.e.g. !!null, !!int ...).

Just upgrade the library. + +Otherwise, you should: + +1.
