+# 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
+var someObject = {}
+cache.set(someObject, 'a value')
+cache.set('[object Object]', 'a different value')
+assert.equal(cache.get(someObject), 'a value')
+
+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

+# pseudomap
+
+A thing that is a lot like ES6 `Map`, but without iterators, for use
+in environments where `for..of` syntax and `Map` are not available.
+
+If you need iterators, or just in general a more faithful polyfill to
+ES6 Maps, check out [es6-map](http://npm.im/es6-map).
+
+If you are in an environment where `Map` is supported, then that will
+be returned instead, unless `process.env.TEST_PSEUDOMAP` is set.
+
+You can use any value as keys, and any value as data. Setting again
+with the identical key will overwrite the previous value.
+
+Internally, data is stored on an `Object.create(null)` style object.
+The key is coerced to a string to generate the key on the internal
+data-bag object. The original key used is stored along with the data.
+
+In the event of a stringified-key collision, a new key is generated by
+appending an increasing number to the stringified-key until finding
+either the intended key or an empty spot.
+
+Note that because object traversal order of plain objects is not
+guaranteed to be identical to insertion order, the insertion order
+guarantee of `Map.prototype.forEach` is not guaranteed in this
+implementation. However, in all versions of Node.js and V8 where this
+module works, `forEach` does traverse data in insertion order.
+
+## API
+
+Most of the [Map
+API](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map),
+with the following exceptions:
+
+1. A `Map` object is not an iterator.
+2. `values`, `keys`, and `entries` methods are not implemented,
+ because they return iterators.
+3. The argument to the constructor can be an Array of `[key, value]`
+ pairs, or a `Map` or `PseudoMap` object. But, since iterators
+ aren't used, passing any plain-old iterator won't initialize the
+ map properly.
+
+## USAGE
+
+Use just like a regular ES6 Map.
+
+```javascript
+var PseudoMap = require('pseudomap')
+
+// optionally provide a pseudomap, or an array of [key,value] pairs
+// as the argument to initialize the map with
+var myMap = new PseudoMap()
+
+myMap.set(1, 'number 1')
+myMap.set('1', 'string 1')
+var akey = {}
+var bkey = {}
+myMap.set(akey, { some: 'data' })
+myMap.set(bkey, { some: 'other data' })
+```

+# 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
+
+The list to which this node belongs. (Null if it does not belong to
+any list.)
