> Create a read stream filtered and ordered by glob patterns. The keys in the

database should be absolute, unix-like paths.

## example

```js

var level  = require('level-test')({ mem: true })

  , glob   = require('level-glob')

  , concat = require('concat-stream')

// create a database

var db = level()

// insert some data

var ops = [

  {type: 'put', key: '/readme.md',      value: 'readme' },

  {type: 'put', key: '/assets/app.js',  value: 'js'     },

  {type: 'put', key: '/assets/app.css', value: 'css'    }

]

db.batch(ops, function(){

  var opts = { values: true, keys: false }

  // aggregates multiple streams

  glob(db, ['assets/*', '/*'], opts)

    .pipe(concat(function(value){

      console.log(value === 'cssjsreadme')

    }))

  // but those streams are ordered

  glob(db, ['/*', 'assets/*'], opts)

    .pipe(concat(function(value){

      console.log(value === 'readmecssjs')

    }))

  // negation only applies to patterns before it

  glob(db, ['assets/*', '!**.md', '/*'], opts)

    .pipe(concat(function(value){

      console.log(value === 'cssjsreadme')

    }))

  // so this negative glob does have an effect

  glob(db, ['assets/*', '/*', '!**.md'], opts)

    .pipe(concat(function(value){

      console.log(value === 'cssjs')

    }))

})

```

## usage

### `glob(db, patterns(s)[, options])`

Create a readstream filtered by one or more glob patterns.

### `glob.install(db)`

Add a `createGlobStream` method to `db`.

```js

glob.install(db);

db.createGlobStream('/**/*.png', options);

```

## install

With [npm](https://npmjs.org) do:

```

npm install level-glob

```
