* Class Asset |

|
29
|
|
|
* This class locates assets accounting for possible overrides in public/overrides/$bundleName or in the |
|
30
|
|
|
* active theme. It is foremost used by the zasset() Twig template plugin, but can be utilized as a standalone |
|
31
|
|
|
* service as well. All asset types (js, css, images) will work. |
|
32
|
|
|
* |
|
33
|
|
|
* Asset paths must begin with `@` in order to be processed (and possibly overridden) by this class. |
|
34
|
|
|
* Assets that do not contain `@` are passed through to the standard symfony asset management. |
|
35
|
|
|
* |
|
36
|
|
|
* Overrides are in this order: |
|
37
|
|
|
* 1) public/overrides/$bundleName/* |
|
38
|
|
|
* 2) public/themes/$theme/$bundleName/* |
|
39
|
|
|
* 3) public/modules/$bundleName/* |
