# exorcist [![build status](https://secure.travis-ci.org/thlorenz/exorcist.svg?branch=master)](http://travis-ci.org/thlorenz/exorcist)

Externalizes the source map found inside a stream to an external `.map` file or stream.

Works with both JavaScript and CSS input streams.

```js
var browserify = require('browserify')
  , path       = require('path')
  , fs         = require('fs')
  , exorcist   = require('exorcist')
  , mapfile    = path.join(__dirname, 'bundle.js.map')

// from a file, to a file, and send source map to its own file
browserify({debug: true})
  .require(require.resolve('./main'), { entry: true })
  .bundle()
  .pipe(exorcist(mapfile))
  .pipe(fs.createWriteStream(path.join(__dirname, 'bundle.js'), 'utf8'))

//  from a stream, to a stream, and send source map to a stream
browserify([readableSourceStream], browserifyOptions)
  .bundle()
  .pipe(exorcist(targetSourceMapStream, '/url/path/to/replace/source/comment/with/bundle.js'))
  .pipe(writableTargetStream)
```

### command line example

```
browserify main.js --debug | exorcist bundle.js.map > bundle.js
```

## Usage

```
exorcist map_file [options]

Externalizes the source map of the file streamed in.

The source map is written as JSON to map_file, and the original file is streamed out with its
  sourceMappingURL set to the path of map_file (or to the value of the --url option).

OPTIONS:

--base -b   Base path for calculating relative source paths.
                          (default: use absolute paths)

--root -r   Root URL for loading relative source paths.
                          Set as sourceRoot in the source map.
                          (default: '')

--url -u   Full URL to source map.
                          Set as sourceMappingURL in the output stream.
                          (default: map_file)

--error-on-missing -e   Abort with error if no map is found in the stream.
                          (default: warn but still pipe through source)

EXAMPLE:

Bundle main.js with browserify into bundle.js and externalize the map to bundle.js.map.

browserify main.js --debug | exorcist bundle.js.map > bundle.js
```
