In October of the same +year, the PythonLabs team moved to Digital Creations, which became +Zope Corporation. In 2001, the Python Software Foundation (PSF, see +https://www.python.org/psf/) was formed, a non-profit organization +created specifically to own Python-related Intellectual Property. +Zope Corporation was a sponsoring member of the PSF. + +All Python releases are Open Source (see http://www.opensource.org for +the Open Source Definition). Historically, most, but not all, Python +releases have also been GPL-compatible; the table below summarizes +the various releases. + + Release Derived Year Owner GPL- + from compatible?

All Python licenses, unlike the GPL, let you distribute + a modified version without making your changes open source. The + GPL-compatible licenses make it possible to combine Python with + other software that is released under the GPL; the others don't. + +(2) According to Richard Stallman, 1.6.1 is not GPL-compatible, + because its license has a choice of law clause. According to + CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1 + is "not incompatible" with the GPL. + +Thanks to the many outside volunteers who have worked under Guido's +direction to make these releases possible. + + +B.

Returns either a +plain object, a string, a number, `null` or `undefined`, or throws `YAMLException` on error. By default, does +not support regexps, functions and undefined. + +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_SCHEMA`)_ - specifies a schema to use. + - `FAILSAFE_SCHEMA` - only strings, arrays and plain objects: + https://www.yaml.org/spec/1.2/spec.html#id2802346 + - `JSON_SCHEMA` - all JSON-supported types: + https://www.yaml.org/spec/1.2/spec.html#id2803231 + - `CORE_SCHEMA` - same as `JSON_SCHEMA`: + https://www.yaml.org/spec/1.2/spec.html#id2804923 + - `DEFAULT_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. + + +### loadAll (string [, iterator] [, options ]) + +Same as `load()`, but understands multi-document sources.

Uses `DEFAULT_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_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. Set `-1` for unlimited 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. +- `quotingType` _(`'` or `"`, default: `'`)_ - strings will be quoted using this quoting style. If you specify single quotes, double quotes will still be used for non-printable characters. +- `forceQuotes` _(default: `false`)_ - if `true`, all non-key strings will be quoted even if they normally don't need to. +- `replacer` - callback `function (key, value)` called recursively on each key/value in source object (see `replacer` docs for `JSON.stringify`). + +The following table show availlable styles (e.g. "canonical", +"binary"...) available for each tag (.e.g. !!null, !!int ...).
