-[](https://www.npmjs.org/package/argparse)
-
-CLI arguments parser for node.js. Javascript port of python's
-[argparse](http://docs.python.org/dev/library/argparse.html) module
-(original version 3.2). That's a full port, except some very rare options,
-recorded in issue tracker.
-
-**NB. Difference with original.**
-
-- Method names changed to camelCase. See [generated docs](http://nodeca.github.com/argparse/).
-- Use `defaultValue` instead of `default`.
-- Use `argparse.Const.REMAINDER` instead of `argparse.REMAINDER`, and
- similarly for constant values `OPTIONAL`, `ZERO_OR_MORE`, and `ONE_OR_MORE`
- (aliases for `nargs` values `'?'`, `'*'`, `'+'`, respectively), and
- `SUPPRESS`.
-
-
-Example
-=======
-
-test.js file:
-
-```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 example'
-});
-parser.addArgument(
- [ '-f', '--foo' ],
- {
- help: 'foo bar'
- }
-);
-parser.addArgument(
- [ '-b', '--bar' ],
- {
- help: 'bar foo'
- }
-);
-parser.addArgument(
- '--baz',
- {
- help: 'baz bar'
- }
-);
-var args = parser.parseArgs();
-console.dir(args);
-```
-
-Display help:
-
-```
-$ ./test.js -h
-usage: example.js [-h] [-v] [-f FOO] [-b BAR] [--baz BAZ]
-
-Argparse example
-
-Optional arguments:
- -h, --help Show this help message and exit.
- -v, --version Show program's version number and exit.
- -f FOO, --foo FOO foo bar
- -b BAR, --bar BAR bar foo
- --baz BAZ baz bar
-```
-
-Parse arguments:
-
-```
-$ ./test.js -f=3 --bar=4 --baz 5
-{ foo: '3', bar: '4', baz: '5' }
-```

-ArgumentParser objects
-======================
-
-```
-new ArgumentParser({parameters hash});
-```
-
-Creates a new ArgumentParser object.
-
-**Supported params:**
-
-- ```description``` - Text to display before the argument help.
-- ```epilog``` - Text to display after the argument help.
-- ```addHelp``` - Add a -h/–help option to the parser. (default: true)
-- ```argumentDefault``` - Set the global default value for arguments. (default: null)
-- ```parents``` - A list of ArgumentParser objects whose arguments should also be included.
-- ```prefixChars``` - The set of characters that prefix optional arguments. (default: ‘-‘)
-- ```formatterClass``` - A class for customizing the help output.
-- ```prog``` - The name of the program (default: `path.basename(process.argv[1])`)
-- ```usage``` - The string describing the program usage (default: generated)
-- ```conflictHandler``` - Usually unnecessary, defines strategy for resolving conflicting optionals.
-
-**Not supported yet**
-
-- ```fromfilePrefixChars``` - The set of characters that prefix files from which additional arguments should be read.
-
-
-Details in [original ArgumentParser guide](http://docs.python.org/dev/library/argparse.html#argumentparser-objects)
-
-
-addArgument() method
-====================
-
-```
-ArgumentParser.addArgument(name or flag or [name] or [flags...], {options})
-```
-
-Defines how a single command-line argument should be parsed.
-
-- ```name or flag or [name] or [flags...]``` - Either a positional name
- (e.g., `'foo'`), a single option (e.g., `'-f'` or `'--foo'`), an array
- of a single positional name (e.g., `['foo']`), or an array of options
- (e.g., `['-f', '--foo']`).
-
-Options:
-
-- ```action``` - The basic type of action to be taken when this argument is encountered at the command line.
-- ```nargs```- The number of command-line arguments that should be consumed.
-- ```constant``` - A constant value required by some action and nargs selections.
-- ```defaultValue``` - The value produced if the argument is absent from the command line.
-- ```type``` - The type to which the command-line argument should be converted.
-- ```choices``` - A container of the allowable values for the argument.
-- ```required``` - Whether or not the command-line option may be omitted (optionals only).
-- ```help``` - A brief description of what the argument does.
-- ```metavar``` - A name for the argument in usage messages.
-- ```dest``` - The name of the attribute to be added to the object returned by parseArgs().
-
-Details in [original add_argument guide](http://docs.python.org/dev/library/argparse.html#the-add-argument-method)
-
-
-Action (some details)
-================
-
-ArgumentParser objects associate command-line arguments with actions.
-These actions can do just about anything with the command-line arguments associated
-with them, though most actions simply add an attribute to the object returned by
-parseArgs(). The action keyword argument specifies how the command-line arguments
-should be handled. The supported actions are:
-
-- ```store``` - Just stores the argument’s value. This is the default action.
-- ```storeConst``` - Stores value, specified by the const keyword argument.
- (Note that the const keyword argument defaults to the rather unhelpful None.)
- The 'storeConst' action is most commonly used with optional arguments, that
- specify some sort of flag.
-- ```storeTrue``` and ```storeFalse``` - Stores values True and False
- respectively. These are special cases of 'storeConst'.
-- ```append``` - Stores a list, and appends each argument value to the list.
- This is useful to allow an option to be specified multiple times.
-- ```appendConst``` - Stores a list, and appends value, specified by the
- const keyword argument to the list. (Note, that the const keyword argument defaults
- is None.) 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. Expects a `version=`
- keyword argument in the addArgument() call.
-
-Details in [original action guide](http://docs.python.org/dev/library/argparse.html#action)

-Sub-commands
-============
-
-ArgumentParser.addSubparsers()
-
-Many programs split their functionality into a number of sub-commands, for
-example, the svn program can invoke sub-commands like `svn checkout`, `svn update`,
-and `svn commit`. 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);
-
-```

-/**
- * class Action
- *
- * Base class for all actions
- * Do not call in your code, use this class only for inherits your own action
- *
- * Information about how to convert command line strings to Javascript objects.
- * Action objects are used by an ArgumentParser to represent the information
- * needed to parse a single argument from one or more strings from the command
- * line. The keyword arguments to the Action constructor are also all attributes
- * of Action instances.
- *
- * ##### Allowed keywords:
- *
- * - `store`
- * - `storeConstant`
- * - `storeTrue`
- * - `storeFalse`
- * - `append`
- * - `appendConstant`
- * - `count`
- * - `help`
- * - `version`
- *
- * Information about action options see [[Action.new]]

- * new Action(options)
- *
- * Base class for all actions. Used only for inherits
- *
- *
- * ##### Options:
- *
- * - `optionStrings` A list of command-line option strings for the action.
- * - `dest` Attribute to hold the created object(s)
- * - `nargs` The number of command-line arguments that should be consumed.
- * By default, one argument will be consumed and a single value will be
- * produced.
- * - `constant` Default value for an action with no value.
- * - `defaultValue` The value to be produced if the option is not specified.
- * - `type` Cast to 'string'|'int'|'float'|'complex'|function (string). If
- * None, 'string'.
- * - `choices` The choices available.
- * - `required` True if the action must always be specified at the command
- * line.
- * - `help` The help describing the argument.
- * - `metavar` The name to be used for the option's argument with the help
- * string. If None, the 'dest' value will be used as the name.
- *
- * ##### nargs supported values:
- *
- * - `N` (an integer) consumes N arguments (and produces a list)
- * - `?` consumes zero or one arguments
- * - `*` consumes zero or more arguments (and produces a list)
- * - `+` consumes one or more arguments (and produces a list)
- *
- * Note: that the difference between the default and nargs=1 is that with the
- * default, a single value will be produced, while with nargs=1, a list
- * containing a single value will be produced.

-JS-YAML - YAML 1.2 parser / writer for JavaScript
-=================================================
-
-[](https://travis-ci.org/nodeca/js-yaml)
-[](https://www.npmjs.org/package/js-yaml)
-
-__[Online Demo](http://nodeca.github.com/js-yaml/)__
-
-
-This is an implementation of [YAML](http://yaml.org/), a human-friendly data
-serialization language. Started as [PyYAML](http://pyyaml.org/) port, it was
-completely rewritten from scratch. Now it's very fast, and supports 1.2 spec.
-
-
-Installation
-------------
-
-### YAML module for node.js
-
-```
-npm install js-yaml
-```
-
-
-### CLI executable
-
-If you want to inspect your YAML files from CLI, install js-yaml globally:
-
-```
-npm install -g js-yaml
-```
-
-#### Usage
-
-```
-usage: js-yaml [-h] [-v] [-c] [-t] file
-
-Positional arguments:
- file File with YAML document(s)
-
-Optional arguments:
- -h, --help Show this help message and exit.
- -v, --version Show program's version number and exit.
- -c, --compact Display errors in compact mode
- -t, --trace Show stack trace on error
-```
-
-
-### Bundled YAML library for browsers
-
-``` html
-
-
-
-
-```
-
-Browser support was done mostly for the online demo. If you find any errors - feel
-free to send pull requests with fixes. Also note, that IE and other old browsers
-needs [es5-shims](https://github.com/kriskowal/es5-shim) to operate.
-
-Notes:
-
-1. We have no resources to support browserified version. Don't expect it to be
- well tested. Don't expect fast fixes if something goes wrong there.
-2. `!!js/function` in browser bundle will not work by default. If you really need
- it - load `esprima` parser first (via amd or directly).
-3. `!!bin` in browser will return `Array`, because browsers do not support
- node.js `Buffer` and adding Buffer shims is completely useless on practice.
-
-
-API
----
-
-Here we cover the most 'useful' methods. If you need advanced details (creating
-your own tags), see [wiki](https://github.com/nodeca/js-yaml/wiki) and
-[examples](https://github.com/nodeca/js-yaml/tree/master/examples) for more
-info.
-
-``` javascript
-const yaml = require('js-yaml');
-const fs = require('fs');
-
-// Get document, or throw exception on error
-try {
- const doc = yaml.safeLoad(fs.readFileSync('/home/ixti/example.yml', 'utf8'));
- console.log(doc);
-} catch (e) {
- console.log(e);
-}
-```
-
-
-### safeLoad (string [ , options ])
-
-**Recommended loading way.** Parses `string` as single YAML document. 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": ! "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 ...). Yaml
-output is shown on the right side after `=>` (default setting) or `->`:
-
-``` none
-!!null
- "canonical" -> "~"
- "lowercase" => "null"
- "uppercase" -> "NULL"
- "camelcase" -> "Null"
-
-!!int
- "binary" -> "0b1", "0b101010", "0b1110001111010"
- "octal" -> "01", "052", "016172"
- "decimal" => "1", "42", "7290"
- "hexadecimal" -> "0x1", "0x2A", "0x1C7A"
-
-!!bool
- "lowercase" => "true", "false"
- "uppercase" -> "TRUE", "FALSE"
- "camelcase" -> "True", "False"
-
-!!float
- "lowercase" => ".nan", '.inf'
- "uppercase" -> ".NAN", '.INF'
- "camelcase" -> ".NaN", '.Inf'
-```
-
-Example:
-
-``` javascript
-safeDump (object, {
- 'styles': {
- '!!null': 'canonical' // dump null as ~
- },
- 'sortKeys': true // sort object keys
-});
-```
-
-### dump (object [ , options ])
-
-Same as `safeDump()` but without limits (uses `DEFAULT_FULL_SCHEMA` by default).
-
-
-Supported YAML types
---------------------
-
-The list of standard YAML tags and corresponding JavaScipt types. See also
-[YAML tag discussion](http://pyyaml.org/wiki/YAMLTagDiscussion) and
-[YAML types repository](http://yaml.org/type/).
-
-```
-!!null '' # null
-!!bool 'yes' # bool
-!!int '3...' # number
-!!float '3.14...' # number
-!!binary '...base64...' # buffer
-!!timestamp 'YYYY-...' # date
-!!omap [ ... ] # array of key-value pairs
-!!pairs [ ... ] # array or array pairs
-!!set { ... } # array of objects with given keys and null values
-!!str '...' # string
-!!seq [ ... ] # array
-!!map { ... } # object
-```
-
-**JavaScript-specific tags**
-
-```
-!!js/regexp /pattern/gim # RegExp
-!!js/undefined '' # Undefined
-!!js/function 'function () {...}' # Function
-```
-
-Caveats
--------
-
-Note, that you use arrays or objects as key in JS-YAML. JS does not allow objects
-or arrays as keys, and stringifies (by calling `toString()` method) them at the
-moment of adding them.
-
-``` yaml
----
-? [ foo, bar ]
-: - baz
-? { foo: bar }
-: - baz
- - baz
-```
-
-``` javascript
-{ "foo,bar": ["baz"], "[object Object]": ["baz", "baz"] }
-```
-
-Also, reading of properties on implicit block mapping keys is not supported yet.
-So, the following YAML document cannot be loaded.
-
-``` yaml
-&anchor foo:
- foo: bar
- *anchor: duplicate key
- baz: bat
- *anchor: duplicate key
-```

-
-**Esprima** ([esprima.org](http://esprima.org), BSD license) is a high performance,
-standard-compliant [ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
-parser written in ECMAScript (also popularly known as
-[JavaScript](https://en.wikipedia.org/wiki/JavaScript)).
-Esprima is created and maintained by [Ariya Hidayat](https://twitter.com/ariyahidayat),
-with the help of [many contributors](https://github.com/jquery/esprima/contributors).
-
-### Features
-
-- Full support for ECMAScript 2017 ([ECMA-262 8th Edition](http://www.ecma-international.org/publications/standards/Ecma-262.htm))
-- Sensible [syntax tree format](https://github.com/estree/estree/blob/master/es5.md) as standardized by [ESTree project](https://github.com/estree/estree)
-- Experimental support for [JSX](https://facebook.github.io/jsx/), a syntax extension for [React](https://facebook.github.io/react/)
-- Optional tracking of syntax node location (index-based and line-column)
-- [Heavily tested](http://esprima.org/test/ci.html) (~1500 [unit tests](https://github.com/jquery/esprima/tree/master/test/fixtures) with [full code coverage](https://codecov.io/github/jquery/esprima))
-
-### API
-
-Esprima can be used to perform [lexical analysis](https://en.wikipedia.org/wiki/Lexical_analysis) (tokenization) or [syntactic analysis](https://en.wikipedia.org/wiki/Parsing) (parsing) of a JavaScript program.
-
-A simple example on Node.js REPL:
-
-```javascript
-> var esprima = require('esprima');
-> var program = 'const answer = 42';
-
-> esprima.tokenize(program);
-[ { type: 'Keyword', value: 'const' },
- { type: 'Identifier', value: 'answer' },
- { type: 'Punctuator', value: '=' },
- { type: 'Numeric', value: '42' } ]
-
-> esprima.parseScript(program);
-{ type: 'Program',
- body:
- [ { type: 'VariableDeclaration',
- declarations: [Object],
- kind: 'const' } ],
- sourceType: 'script' }
-```
-
-For more information, please read the [complete documentation](http://esprima.org/doc).
