| 8 * This file is meant to be loaded as a ChromeWorker. It accepts messages which | |
| 9 * have data of the form: | |
| 10 * | |
| 11 * { id, url, indent, source } | |
| 12 * | |
| 13 * Where `id` is a unique ID to identify this request, `url` is the url of the | |
| 14 * source being pretty printed, `indent` is the number of spaces to indent the | |
| 15 * code by, and `source` is the source text. | |
| 16 * | |
| 17 * On success, the worker responds with a message of the form: | |
| 18 * | |
| 19 * { id, code, mappings } | |
| 20 * | |
| 21 * Where `id` is the same unique ID from the request, `code` is the pretty | |
| 22 * printed source text, and `mappings` is an array or source mappings from the | |
| 23 * pretty printed code back to the ugly source text. | |
| 24 * | |
| 25 * In the case of an error, the worker responds with a message of the form: | |
| 26 * | |
| 27 * { id, error } | |
