/**

 * Firefox/Spidermonkey, however, this code does not cause syntax
 * errors in older engines.  This code should continue to work and
 * will in fact improve over time as the language improves.
 *
 * Decorates a generator function such that:
 *  - it may yield promises
 *  - execution will continue when that promise is fulfilled
 *  - the value of the yield expression will be the fulfilled value
 *  - it returns a promise for the return value (when the generator
 *    stops iterating)
 *  - the decorated function returns a promise for the return value
 *    of the generator or the first rejected promise among those
 *    yielded.
 *  - if an error is thrown in the generator, it propagates through
 *    every following yield until it is caught, or until it escapes
 *    the generator function altogether, and is translated into a
 *    rejection for the promise returned by the decorated generator.
 *  - in present implementations of generators, when a generator
 *    function is complete, it throws ``StopIteration``, ``return`` is
 *    a syntax error in the presence of ``yield``, so there is no
 *    observable return value. There is a proposal[1] to add support
 *    for ``return``, which would permit the value to be carried by a
 *    ``StopIteration`` instance, in which case it would fulfill the
 *    promise returned by the asynchronous generator.  This can be
 *    emulated today by throwing StopIteration explicitly with a value
 *    property.

  A JavaScript tokenizer / parser / beautifier / compressor.

  This version is suitable for Node.js.  With minimal changes (the
  exports stuff) it should work on any JS platform.

  This file contains the tokenizer/parser.  It is a port to JavaScript
  of parse-js [1], a JavaScript parser library written in Common Lisp
  by Marijn Haverbeke.  Thank you Marijn!

  [1] http://marijn.haverbeke.nl/parse-js/

  Exported functions:

    - tokenizer(code) -- returns a function.  Call the returned
      function to fetch the next token.

    - parse(code) -- returns an AST of the given JavaScript code.

If the project has a\n  package.json entry for "amd": {} then this flag is not needed.\n* -amdlog: Prints out more details on files converted to AMD, if AMD conversion\n  is done.\n\n**archive** is in one of the following formats:\n\n* user/repo: Download the zip file from GitHub for the user/repo, using the\n  latest version tag, or "master" if no version tags.\n* user/repo/tag: Download the zip file from GitHub for the user/repo, using the\n  specific tag/branch name listed.\n* user/repo/tag#specific/file.js: Download zip file from GitHub for the user/\n  repo, using the specific tag/branch name listed, then extracting only\n  the specific/file.js from that archive and installing it.\n* http://some.domain.com/path/to/archive.zip: Downloads the zip file and\n  installs it.\n* http://some.domain.com/path/to/archive.zip#specific/file.js: Download\n  the zip file and only install specific/file.js.\n* symlink:path/to/directory/or/file.js: Creates a symlink to the specific\n  location in the project. If it is a directory and the project using the\n  directory is an AMD project, an adapter module will also be created.\n* local:paht/to/directory: Copies the local directory. A local directory is\n  also checked when the "some/thing" archive name is used -- if there is no\n  local file match, it is assumed to be a GitHub URL.\n\nIf **localName** is specified then that name is used for the installed name.\nIf the installed item is a directory, the directory will have this name. If\na specific file from the the archive, the file will have this name.\n\nIf **localName** is not specified, the installed directory name will be the\nname of the .zip file without the zip extension, or if a GitHub\nreference, the repo name. If it is a specific file from within a zip file,\nthen that file\'s name will be used.\n\n## Examples\n\nThis one fetches Underscore and converts it to have an AMD wrapper. Underscore\nstill registers a global export, but AMD code can get a local reference\nthrough the module ID:\n\n    volo add -amd documentcloud/underscore exports=_\n\nWhen the -amd flag is used, the the **amdify** command is used to convert\nthe file downloaded by the **add** command, so the named arguments supported\nby **amdify** can als be used with **add**.\n\nHere is a command that fetches Backbone and wraps in it in an AMD define() call,\nspecifying \'jquery\' and \'underscore\' as dependencies:\n\n    volo add -amd documentcloud/backbone depend=underscore,jquery exports=Backbone\n\n\n## Installation Details\n\nFor the directory in which add is run, it will look for the following to know\nwhere to install:\n\n* Looks for a package.json file and if there is an amd.baseUrl defined in it.\n* Looks for a **js** directory\n* Looks for a **scripts** directory\n\nIf none of those result in a subdirectory for installation, then the current\nworking directory is used.\n\nIf the archive has a top level .js file in it and it is the same name\nas the repo\'s/zip file name, then only that .js file will be installed.\n\nOr, if there is only one top level .js file in the repo and it has a\n/*package.json */ comment with JSON inside that comment, it will be used.\n';});

If the export object has a \'noConflict\' method on it, then it will\nbe called as part of exporting the module value:\n\n    volo amdify www/js/lib.js depends=jquery exports=lib\n\nresults in a transform that looks roughly like:\n\n    define([\'jquery\'], function () {\n\n        //original contents in here.\n\n        return lib;\n    });\n\nIf you want "-noConflict" called on the exports value:\n\n    volo amdify -noConflict www/js/lib.js depends=jquery exports=lib\n\nresults in a transform that looks roughly like:\n\n    define([\'jquery\'], function () {\n\n        //original contents in here.\n\n        if (lib.noConflict)) {\n            lib.noConflict(true);\n        }\n        return lib;\n    });\n\n**Be careful with -noConflict**. You most likely do not want to use it if\nyou have other code that has been amdify\'d that depends on this amdify\'d code.\nFor instance, using amdify on underscore.js with -noConflict is bad since\nbackbone.js depends on underscore, and it looks for a global _ value.\n\namdify will set the "this" value for the original contents to be the global\nobject.\n\nIdeally the target file would optionally call define() itself, and use\nthe local dependency references instead of browser globals. However, for\nbootstrapping existing projects to use an AMD loader, amdify can be useful to\nget started.\n\nUsing amdify will produce code that is uglier than doing a proper code change\nto add optional an optional define() call. For better code examples, see:\nhttps://github.com/umdjs/umd\n';});

However, in an AMD, browser-based deployment, only one IO operation per\nmodule, at most, is advised.\n\nThis command determines the nested package names and locations, and updates\nany require(\'\') calls in the modules to use a relative module ID so that the\nmodules can be used in an AMD project.\n\nIt then converts the modules to have an AMD define() wrapper.\n\n## Example\n\n    > mkdir node_modules\n    > npm install foo\n    > volo npmrel node_modules/foo\n\nNow you can move node_modules/foo.js and node_modules/foo to the baseUrl of\nyour AMD project.\n\n## Notes\n\nThis will not work for all node modules. In particular, if the module calculates\nthe require dependency:\n\n    var a = require(someCondition ? \'a\' : \'a1\');\n\nor\n\n    var name = prefix + \'/\' + action,\n        impl = require(name);\n\nThis command also does not create "browser friendly" versions of the core\nmodules like "fs". It only converts module IDs that map to packages that\nare in the local node_modules directory, but keeps all other IDs intact.\n';});

/***********************************************************************

  A JavaScript tokenizer / parser / beautifier / compressor.

  This version is suitable for Node.js.  With minimal changes (the
  exports stuff) it should work on any JS platform.

  This file implements some AST processors.  They work on data built
  by parse-js.

  Exported functions:

    - ast_mangle(ast, options) -- mangles the variable/function names
      in the AST.  Returns an AST.

    - ast_squeeze(ast) -- employs various optimizations to make the
      final generated code even smaller.  Returns an AST.

    - gen_code(ast, options) -- generates JS code from the AST.  Pass
      true (or an object, see the code for some options) as second
      argument to get "pretty" (indented) code.
