/**
|
|
* This file is meant to be loaded as a ChromeWorker. It accepts messages which
|
|
* have data of the form:
|
|
*
|
|
* { id, url, indent, source }
|
|
*
|
|
* Where `id` is a unique ID to identify this request, `url` is the url of the
|
|
* source being pretty printed, `indent` is the number of spaces to indent the
|
|
* code by, and `source` is the source text.
|
|
*
|
|
* On success, the worker responds with a message of the form:
|
|
*
|
|
* { id, code, mappings }
|
|
*
|
|
* Where `id` is the same unique ID from the request, `code` is the pretty
|
|
* printed source text, and `mappings` is an array or source mappings from the
|
|
* pretty printed code back to the ugly source text.
|
|
*
|
|
* In the case of an error, the worker responds with a message of the form:
|
|
*
|
|
* { id, error }
