|
|
Usage |
|
===== |
|
|
|
### `sourceMappingURL.getFrom(code)` ### |
|
|
|
Returns the url of the sourceMappingURL comment in `code`. Returns `null` if |
|
there is no such comment. |
|
|
|
### `sourceMappingURL.existsIn(code)` ### |
|
|
|
Returns `true` if there is a sourceMappingURL comment in `code`, or `false` |
|
otherwise. |
|
|
|
### `sourceMappingURL.removeFrom(code)` ### |
|
|
|
Removes the sourceMappingURL comment in `code`. Does nothing if there is no |
|
such comment. Returns the updated `code`. |
|
|
|
### `sourceMappingURL.insertBefore(code, string)` ### |
|
|
|
Inserts `string` before the sourceMappingURL comment in `code`. Appends |
|
`string` to `code` if there is no such comment. |
|
|
|
Lets you append something to a file without worrying about burying the |
|
sourceMappingURL comment (by keeping it at the end of the file). |
|
|
|
### `sourceMappingURL.regex` ### |
|
|
|
The regex that is used to match sourceMappingURL comments. It matches both `//` |
|
and `/**/` comments, thus supporting both JavaScript and CSS. |
|
|
|

|
Tests |
|
===== |
|
|
|
Start by running `npm test`, which lints the code and runs the test suite in Node.js. |
|
|
|
To run the tests in a browser, run `testling` (`npm install -g testling`) or `testling -u`. |
