HISTORY OF THE SOFTWARE +========================== + +Python was created in the early 1990s by Guido van Rossum at Stichting +Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands +as a successor of a language called ABC. Guido remains Python's +principal author, although it includes many contributions from others. + +In 1995, Guido continued his work on Python at the Corporation for +National Research Initiatives (CNRI, see http://www.cnri.reston.va.us) +in Reston, Virginia where he released several versions of the +software. + +In May 2000, Guido and the Python core development team moved to +BeOpen.com to form the BeOpen PythonLabs team. 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.

As the + * example above shows, the add_argument() method is used to populate + * the parser with actions for optional and positional arguments. Then + * the parse_args() method is invoked to convert the args at the + * command-line into an object with attributes. + * + * - ArgumentError -- The exception raised by ArgumentParser objects when + * there are errors with the parser's actions. Errors raised while + * parsing the command-line are caught by ArgumentParser and emitted + * as command-line messages. + * + * - FileType -- A factory for defining types of files to be created. As the + * example above shows, instances of FileType are typically passed as + * the type= argument of add_argument() calls. + * + * - Action -- The base class for parser actions. Typically actions are + * selected by passing strings like 'store_true' or 'append_const' to + * the action= argument of add_argument(). However, for greater + * customization of ArgumentParser actions, subclasses of Action may + * be defined and passed as the action= argument. + * + * - HelpFormatter, RawDescriptionHelpFormatter, RawTextHelpFormatter, + * ArgumentDefaultsHelpFormatter -- Formatter classes which + * may be passed as the formatter_class= argument to the + * ArgumentParser constructor. HelpFormatter is the default, + * RawDescriptionHelpFormatter and RawTextHelpFormatter tell the parser + * not to change the formatting for help text, and + * ArgumentDefaultsHelpFormatter adds information about argument defaults + * to the help. + * + * All other classes in this module are considered implementation details. + * (Also note that HelpFormatter and RawDescriptionHelpFormatter are only + * considered public as object names -- the API of the formatter objects is + * still considered an implementation detail.) + */ + +const SUPPRESS = '==SUPPRESS==' + +const OPTIONAL = '?' +const ZERO_OR_MORE = '*' +const ONE_OR_MORE = '+' +const PARSER = 'A...' +const REMAINDER = '...' +const _UNRECOGNIZED_ARGS_ATTR = '_unrecognized_args' + + +// ================================== +// Utility functions used for porting +// ================================== +const assert = require('assert') +const util = require('util') +const fs = require('fs') +const sub = require('./lib/sub') +const path = require('path') +const repr = util.inspect + +function get_argv() { + // omit first argument (which is assumed to be interpreter - `node`, `coffee`, `ts-node`, etc.) + return process.argv.slice(1) +} + +function get_terminal_size() { + return { + columns: +process.env.COLUMNS || process.stdout.columns || 80 + } +} + +function hasattr(object, name) { + return Object.prototype.hasOwnProperty.call(object, name) +} + +function getattr(object, name, value) { + return hasattr(object, name) ?

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: + 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_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. Applies +`iterator` to each document if specified, or returns array of documents. + +``` javascript +const yaml = require('js-yaml'); + +yaml.loadAll(data, function (doc) { + console.log(doc); +}); +``` + + +### dump (object [ , options ]) + +Serializes `object` as a YAML document. 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 ...).
