Defines 8 functions
Functions that are not part of a class:
| css_store_css(theme_config $theme, $csspath, $csscontent) X-Ref |
| Stores CSS in a file at the given path. This function either succeeds or throws an exception. param: theme_config $theme The theme that the CSS belongs to. param: string $csspath The path to store the CSS at. param: string $csscontent the complete CSS in one string. |
| css_write_file($filename, $content) X-Ref |
| Writes a CSS file. param: string $filename param: string $content |
| css_send_cached_css($csspath, $etag) X-Ref |
| Sends a cached CSS file This function sends the cached CSS file. Remember it is generated on the first request, then optimised/minified, and finally cached for serving. param: string $csspath The path to the CSS file we want to serve. param: string $etag The revision to make sure we utilise any caches. |
| css_send_cached_css_content($csscontent, $etag) X-Ref |
| Sends a cached CSS content param: string $csscontent The actual CSS markup. param: string $etag The revision to make sure we utilise any caches. |
| css_send_temporary_css($css) X-Ref |
| Sends CSS directly and disables all caching. The Content-Length of the body is also included, but the script is not ended. param: string $css The CSS content to send |
| css_send_uncached_css($css) X-Ref |
| Sends CSS directly without caching it. This function takes a raw CSS string, optimises it if required, and then serves it. Turning both themedesignermode and CSS optimiser on at the same time is awful for performance because of the optimiser running here. However it was done so that theme designers could utilise the optimised output during development to help them optimise their CSS... not that they should write lazy CSS. param: string $css |
| css_send_unmodified($lastmodified, $etag) X-Ref |
| Send file not modified headers param: int $lastmodified param: string $etag |
| css_send_css_not_found() X-Ref |
| Sends a 404 message about CSS not being found. |
