-
-A cross platform solution to node's spawn and spawnSync.
-
-
-## Installation
-
-`$ npm install cross-spawn`
-
-If you are using `spawnSync` on node 0.10 or older, you will also need to install `spawn-sync`:
-
-`$ npm install spawn-sync`
-
-
-## Why
-
-Node has issues when using spawn on Windows:
-
-- It ignores [PATHEXT](https://github.com/joyent/node/issues/2318)
-- It does not support [shebangs](http://pt.wikipedia.org/wiki/Shebang)
-- No `options.shell` support on node < v6
-- It does not allow you to run `del` or `dir`
-
-All these issues are handled correctly by `cross-spawn`.
-There are some known modules, such as [win-spawn](https://github.com/ForbesLindesay/win-spawn), that try to solve this but they are either broken or provide faulty escaping of shell arguments.
-
-
-## Usage
-
-Exactly the same way as node's [`spawn`](https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options) or [`spawnSync`](https://nodejs.org/api/child_process.html#child_process_child_process_spawnsync_command_args_options), so it's a drop in replacement.
-
-
-```js
-var spawn = require('cross-spawn');
-
-// Spawn NPM asynchronously
-var child = spawn('npm', ['list', '-g', '-depth', '0'], { stdio: 'inherit' });
-
-// Spawn NPM synchronously
-var results = spawn.sync('npm', ['list', '-g', '-depth', '0'], { stdio: 'inherit' });
-```
-
-
-## Caveats
-
-#### `options.shell` as an alternative to `cross-spawn`
-
-Starting from node v6, `spawn` has a `shell` option that allows you run commands from within a shell. This new option solves most of the problems that `cross-spawn` attempts to solve, but:
-
-- It's not supported in node < v6
-- It has no support for shebangs on Windows
-- You must manually escape the command and arguments which is very error prone, specially when passing user input
-
-If you are using the `shell` option to spawn a command in a cross platform way, consider using `cross-spawn` instead. You have been warned.
-
-
-#### Shebangs
-
-While `cross-spawn` handles shebangs on Windows, its support is limited: e.g.: it doesn't handle arguments after the path, e.g.: `#!/bin/bash -e`.
-
-Remember to always test your code on Windows!
-
-
-## Tests
-
-`$ npm test`

-# lru cache
-
-A cache object that deletes the least-recently-used items.
-
-[![Build Status](https://travis-ci.org/isaacs/node-lru-cache.svg?branch=master)](https://travis-ci.org/isaacs/node-lru-cache) [![Coverage Status](https://coveralls.io/repos/isaacs/node-lru-cache/badge.svg?service=github)](https://coveralls.io/github/isaacs/node-lru-cache)
-
-## Installation:
-
-```javascript
-npm install lru-cache --save
-```
-
-## Usage:
-
-```javascript
-var LRU = require("lru-cache")
-  , options = { max: 500
-              , length: function (n, key) { return n * 2 + key.length }
-              , dispose: function (key, n) { n.close() }
-              , maxAge: 1000 * 60 * 60 }
-  , cache = LRU(options)
-  , otherCache = LRU(50) // sets just the max size
-
-cache.set("key", "value")
-cache.get("key") // "value"
-
-// non-string keys ARE fully supported
-// but note that it must be THE SAME object, not
-// just a JSON-equivalent object.
-var someObject = { a: 1 }
-cache.set(someObject, 'a value')
-// Object keys are not toString()-ed
-cache.set('[object Object]', 'a different value')
-assert.equal(cache.get(someObject), 'a value')
-// A similar object with same keys/values won't work,
-// because it's a different object identity
-assert.equal(cache.get({ a: 1 }), undefined)
-
-cache.reset()    // empty the cache
-```
-
-If you put more stuff in it, then items will fall out.
-
-If you try to put an oversized thing in it, then it'll fall out right
-away.
-
-## Options
-
-* `max` The maximum size of the cache, checked by applying the length
-  function to all values in the cache.  Not setting this is kind of
-  silly, since that's the whole purpose of this lib, but it defaults
-  to `Infinity`.
-* `maxAge` Maximum age in ms.  Items are not pro-actively pruned out
-  as they age, but if you try to get an item that is too old, it'll
-  drop it and return undefined instead of giving it to you.
-* `length` Function that is used to calculate the length of stored
-  items.  If you're storing strings or buffers, then you probably want
-  to do something like `function(n, key){return n.length}`.  The default is
-  `function(){return 1}`, which is fine if you want to store `max`
-  like-sized things.  The item is passed as the first argument, and
-  the key is passed as the second argumnet.
-* `dispose` Function that is called on items when they are dropped
-  from the cache.  This can be handy if you want to close file
-  descriptors or do other cleanup tasks when items are no longer
-  accessible.  Called with `key, value`.  It's called *before*
-  actually removing the item from the internal cache, so if you want
-  to immediately put it back in, you'll have to do that in a
-  `nextTick` or `setTimeout` callback or it won't do anything.
-* `stale` By default, if you set a `maxAge`, it'll only actually pull
-  stale items out of the cache when you `get(key)`.  (That is, it's
-  not pre-emptively doing a `setTimeout` or anything.)  If you set
-  `stale:true`, it'll return the stale value before deleting it.  If
-  you don't set this, then it'll return `undefined` when you try to
-  get a stale entry, as if it had already been deleted.
-* `noDisposeOnSet` By default, if you set a `dispose()` method, then
-  it'll be called whenever a `set()` operation overwrites an existing
-  key.  If you set this option, `dispose()` will only be called when a
-  key falls out of the cache, not when it is overwritten.
-
-## API
-
-* `set(key, value, maxAge)`
-* `get(key) => value`
-
-    Both of these will update the "recently used"-ness of the key.
-    They do what you think. `maxAge` is optional and overrides the
-    cache `maxAge` option if provided.
-
-    If the key is not found, `get()` will return `undefined`.
-
-    The key and val can be any value.
-
-* `peek(key)`
-
-    Returns the key value (or `undefined` if not found) without
-    updating the "recently used"-ness of the key.
-
-    (If you find yourself using this a lot, you *might* be using the
-    wrong sort of data structure, but there are some use cases where
-    it's handy.)
-
-* `del(key)`
-
-    Deletes a key out of the cache.
-
-* `reset()`
-
-    Clear the cache entirely, throwing away all values.
-
-* `has(key)`
-
-    Check if a key is in the cache, without updating the recent-ness
-    or deleting it for being stale.
-
-* `forEach(function(value,key,cache), [thisp])`
-
-    Just like `Array.prototype.forEach`.  Iterates over all the keys
-    in the cache, in order of recent-ness.  (Ie, more recently used
-    items are iterated over first.)
-
-* `rforEach(function(value,key,cache), [thisp])`
-
-    The same as `cache.forEach(...)` but items are iterated over in
-    reverse order.  (ie, less recently used items are iterated over
-    first.)
-
-* `keys()`
-
-    Return an array of the keys in the cache.
-
-* `values()`
-
-    Return an array of the values in the cache.
-
-* `length`
-
-    Return total length of objects in cache taking into account
-    `length` options function.
-
-* `itemCount`
-
-    Return total quantity of objects currently in cache. Note, that
-    `stale` (see options) items are returned as part of this item
-    count.
-
-* `dump()`
-
-    Return an array of the cache entries ready for serialization and usage
-    with 'destinationCache.load(arr)`.
-
-* `load(cacheEntriesArray)`
-
-    Loads another cache entries array, obtained with `sourceCache.dump()`,
-    into the cache. The destination cache is reset before loading new entries
-
-* `prune()`
-
-    Manually iterates over the entire cache proactively pruning old entries

-# yallist
-
-Yet Another Linked List
-
-There are many doubly-linked list implementations like it, but this
-one is mine.
-
-For when an array would be too big, and a Map can't be iterated in
-reverse order.
-
-
-[![Build Status](https://travis-ci.org/isaacs/yallist.svg?branch=master)](https://travis-ci.org/isaacs/yallist) [![Coverage Status](https://coveralls.io/repos/isaacs/yallist/badge.svg?service=github)](https://coveralls.io/github/isaacs/yallist)
-
-## basic usage
-
-```javascript
-var yallist = require('yallist')
-var myList = yallist.create([1, 2, 3])
-myList.push('foo')
-myList.unshift('bar')
-// of course pop() and shift() are there, too
-console.log(myList.toArray()) // ['bar', 1, 2, 3, 'foo']
-myList.forEach(function (k) {
-  // walk the list head to tail
-})
-myList.forEachReverse(function (k, index, list) {
-  // walk the list tail to head
-})
-var myDoubledList = myList.map(function (k) {
-  return k + k
-})
-// now myDoubledList contains ['barbar', 2, 4, 6, 'foofoo']
-// mapReverse is also a thing
-var myDoubledListReverse = myList.mapReverse(function (k) {
-  return k + k
-}) // ['foofoo', 6, 4, 2, 'barbar']
-
-var reduced = myList.reduce(function (set, entry) {
-  set += entry
-  return set
-}, 'start')
-console.log(reduced) // 'startfoo123bar'
-```
-
-## api
-
-The whole API is considered "public".
-
-Functions with the same name as an Array method work more or less the
-same way.
-
-There's reverse versions of most things because that's the point.
-
-### Yallist
-
-Default export, the class that holds and manages a list.
-
-Call it with either a forEach-able (like an array) or a set of
-arguments, to initialize the list.
-
-The Array-ish methods all act like you'd expect.  No magic length,
-though, so if you change that it won't automatically prune or add
-empty spots.
-
-### Yallist.create(..)
-
-Alias for Yallist function.  Some people like factories.
-
-#### yallist.head
-
-The first node in the list
-
-#### yallist.tail
-
-The last node in the list
-
-#### yallist.length
-
-The number of nodes in the list.  (Change this at your peril.  It is
-not magic like Array length.)
-
-#### yallist.toArray()
-
-Convert the list to an array.
-
-#### yallist.forEach(fn, [thisp])
-
-Call a function on each item in the list.
-
-#### yallist.forEachReverse(fn, [thisp])
-
-Call a function on each item in the list, in reverse order.
-
-#### yallist.get(n)
-
-Get the data at position `n` in the list.  If you use this a lot,
-probably better off just using an Array.
-
-#### yallist.getReverse(n)
-
-Get the data at position `n`, counting from the tail.
-
-#### yallist.map(fn, thisp)
-
-Create a new Yallist with the result of calling the function on each
-item.
-
-#### yallist.mapReverse(fn, thisp)
-
-Same as `map`, but in reverse.
-
-#### yallist.pop()
-
-Get the data from the list tail, and remove the tail from the list.
-
-#### yallist.push(item, ...)
-
-Insert one or more items to the tail of the list.
-
-#### yallist.reduce(fn, initialValue)
-
-Like Array.reduce.
-
-#### yallist.reduceReverse
-
-Like Array.reduce, but in reverse.
-
-#### yallist.reverse
-
-Reverse the list in place.
-
-#### yallist.shift()
-
-Get the data from the list head, and remove the head from the list.
-
-#### yallist.slice([from], [to])
-
-Just like Array.slice, but returns a new Yallist.
-
-#### yallist.sliceReverse([from], [to])
-
-Just like yallist.slice, but the result is returned in reverse.
-
-#### yallist.toArray()
-
-Create an array representation of the list.
-
-#### yallist.toArrayReverse()
-
-Create a reversed array representation of the list.
-
-#### yallist.unshift(item, ...)
-
-Insert one or more items to the head of the list.
-
-#### yallist.unshiftNode(node)
-
-Move a Node object to the front of the list.  (That is, pull it out of
-wherever it lives, and make it the new head.)
-
-If the node belongs to a different list, then that list will remove it
-first.
-
-#### yallist.pushNode(node)
-
-Move a Node object to the end of the list.  (That is, pull it out of
-wherever it lives, and make it the new tail.)
-
-If the node belongs to a list already, then that list will remove it
-first.
-
-#### yallist.removeNode(node)
-
-Remove a node from the list, preserving referential integrity of head
-and tail and other nodes.
-
-Will throw an error if you try to have a list remove a node that
-doesn't belong to it.
-
-### Yallist.Node
-
-The class that holds the data and is actually the list.
-
-Call with `var n = new Node(value, previousNode, nextNode)`
-
-Note that if you do direct operations on Nodes themselves, it's very
-easy to get into weird states where the list is broken.  Be careful :)
-
-#### node.next
-
-The next node in the list.
-
-#### node.prev
-
-The previous node in the list.
-
-#### node.value
-
-The data the node contains.
-
-#### node.list
-

-
-> A better [`child_process`](https://nodejs.org/api/child_process.html)
-
-
-## Why
-
-- Promise interface.
-- [Strips EOF](https://github.com/sindresorhus/strip-eof) from the output so you don't have to `stdout.trim()`.
-- Supports [shebang](https://en.wikipedia.org/wiki/Shebang_(Unix)) binaries cross-platform.
-- [Improved Windows support.](https://github.com/IndigoUnited/node-cross-spawn#why)
-- Higher max buffer. 10 MB instead of 200 KB.
-- [Executes locally installed binaries by name.](#preferlocal)
-- [Cleans up spawned processes when the parent process dies.](#cleanup)
-
-
-## Install
-
-```
-$ npm install --save execa
-```
-
-
-## Usage
-
-```js
-const execa = require('execa');
-
-execa('echo', ['unicorns']).then(result => {
-	console.log(result.stdout);
-	//=> 'unicorns'
-});
-
-// pipe the child process stdout to the current stdout
-execa('echo', ['unicorns']).stdout.pipe(process.stdout);
-
-execa.shell('echo unicorns').then(result => {
-	console.log(result.stdout);
-	//=> 'unicorns'
-});
-
-// example of catching an error
-execa.shell('exit 3').catch(error => {
-	console.log(error);
-	/*
-	{
-		message: 'Command failed: /bin/sh -c exit 3'
-		killed: false,
-		code: 3,
-		signal: null,
-		cmd: '/bin/sh -c exit 3',
-		stdout: '',
-		stderr: '',
-		timedOut: false
-	}
-	*/
-});
-```
-
-
-## API
-
-### execa(file, [arguments], [options])
-
-Execute a file.
-
-Think of this as a mix of `child_process.execFile` and `child_process.spawn`.
-
-Returns a [`child_process` instance](https://nodejs.org/api/child_process.html#child_process_class_childprocess), which is enhanced to also be a `Promise` for a result `Object` with `stdout` and `stderr` properties.
-
-### execa.stdout(file, [arguments], [options])
-
-Same as `execa()`, but returns only `stdout`.
-
-### execa.stderr(file, [arguments], [options])
-
-Same as `execa()`, but returns only `stderr`.
-
-### execa.shell(command, [options])
-
-Execute a command through the system shell. Prefer `execa()` whenever possible, as it's both faster and safer.
-
-Returns a [`child_process` instance](https://nodejs.org/api/child_process.html#child_process_class_childprocess).
-
-The `child_process` instance is enhanced to also be promise for a result object with `stdout` and `stderr` properties.
-
-### execa.sync(file, [arguments], [options])
-
-Execute a file synchronously.
-
-Returns the same result object as [`child_process.spawnSync`](https://nodejs.org/api/child_process.html#child_process_child_process_spawnsync_command_args_options).
-
-This method throws an `Error` if the command fails.
-
-### execa.shellSync(file, [options])
-
-Execute a command synchronously through the system shell.
-
-Returns the same result object as [`child_process.spawnSync`](https://nodejs.org/api/child_process.html#child_process_child_process_spawnsync_command_args_options).
-
-### options
-
-Type: `Object`
-
-#### cwd
-
-Type: `string`<br>
-Default: `process.cwd()`
-
-Current working directory of the child process.
-
-#### env
-
-Type: `Object`<br>
-Default: `process.env`
-
-Environment key-value pairs. Extends automatically from `process.env`. Set `extendEnv` to `false` if you don't want this.
-
-#### extendEnv
-
-Type: `boolean`<br>
-Default: `true`
-
-Set to `false` if you don't want to extend the environment variables when providing the `env` property.
-
-#### argv0
-
-Type: `string`
-
-Explicitly set the value of `argv[0]` sent to the child process. This will be set to `command` or `file` if not specified.
-
-#### stdio
-
-Type: `Array` `string`<br>
-Default: `pipe`
-
-Child's [stdio](https://nodejs.org/api/child_process.html#child_process_options_stdio) configuration.
-
-#### detached
-
-Type: `boolean`
-
-Prepare child to run independently of its parent process. Specific behavior [depends on the platform](https://nodejs.org/api/child_process.html#child_process_options_detached).
-
-#### uid
-
-Type: `number`
-
-Sets the user identity of the process.
-
-#### gid
-
-Type: `number`
-
-Sets the group identity of the process.
-
-#### shell
-
-Type: `boolean` `string`<br>
-Default: `false`
-
-If `true`, runs `command` inside of a shell. Uses `/bin/sh` on UNIX and `cmd.exe` on Windows. A different shell can be specified as a string. The shell should understand the `-c` switch on UNIX or `/d /s /c` on Windows.
-
-#### stripEof
-
-Type: `boolean`<br>
-Default: `true`
-
-[Strip EOF](https://github.com/sindresorhus/strip-eof) (last newline) from the output.
-
-#### preferLocal
-
-Type: `boolean`<br>
-Default: `true`
-
-Prefer locally installed binaries when looking for a binary to execute.<br>
-If you `$ npm install foo`, you can then `execa('foo')`.
-
-#### localDir
-
-Type: `string`<br>
-Default: `process.cwd()`
-
-Preferred path to find locally installed binaries in (use with `preferLocal`).
-
-#### input
-
-Type: `string` `Buffer` `stream.Readable`
-
-Write some input to the `stdin` of your binary.<br>
-Streams are not allowed when using the synchronous methods.
-
-#### reject
-
-Type: `boolean`<br>
-Default: `true`
-
-Setting this to `false` resolves the promise with the error instead of rejecting it.
-
-#### cleanup
-
-Type: `boolean`<br>
-Default: `true`
-
-Keep track of the spawned process and `kill` it when the parent process exits.
-
-#### encoding
-
-Type: `string`<br>
-Default: `utf8`
-
-Specify the character encoding used to decode the `stdout` and `stderr` output.
-
-#### timeout
-
-Type: `number`<br>
-Default: `0`
-
-If timeout is greater than `0`, the parent will send the signal identified by the `killSignal` property (the default is `SIGTERM`) if the child runs longer than timeout milliseconds.
-
-#### maxBuffer
-
-Type: `number`<br>
-Default: `10000000` (10MB)
-
-Largest amount of data in bytes allowed on `stdout` or `stderr`.
-
-#### killSignal
-
-Type: `string` `number`<br>
-Default: `SIGTERM`
-
-Signal value to be used when the spawned process will be killed.
-
-#### stdin
-
-Type: `string` `number` `Stream` `undefined` `null`<br>
-Default: `pipe`
-
-Same options as [`stdio`](https://nodejs.org/dist/latest-v6.x/docs/api/child_process.html#child_process_options_stdio).
-
-#### stdout
-
-Type: `string` `number` `Stream` `undefined` `null`<br>
-Default: `pipe`
-
-Same options as [`stdio`](https://nodejs.org/dist/latest-v6.x/docs/api/child_process.html#child_process_options_stdio).
-
-#### stderr
-
-Type: `string` `number` `Stream` `undefined` `null`<br>
-Default: `pipe`
-
-Same options as [`stdio`](https://nodejs.org/dist/latest-v6.x/docs/api/child_process.html#child_process_options_stdio).

-## Tips
-
-### Save and pipe output from a child process
-
-Let's say you want to show the output of a child process in real-time while also saving it to a variable.
-
-```js
-const execa = require('execa');
-const getStream = require('get-stream');
-
-const stream = execa('echo', ['foo']).stdout;
-
-stream.pipe(process.stdout);
-
-getStream(stream).then(value => {
-	console.log('child output:', value);
-});
-```
