Support for EL-evaluated Less-to-CSS compiler --------------------------------------------- Key: RF-12015 URL: https://issues.jboss.org/browse/RF-12015 Project: RichFaces Issue Type: Feature Request Security Level: Public(Everyone can see) Components: core Reporter: Dupont Dupont Fix For: 4-Tracking Suggested approach would be to parse El expression and afterwards execute less processor. Server-side mechanism must be available for executing less. Approach 1 : end-user chooses less or ecss but cannot mix the 2 syntax in the same file. Approach 2 : allow end-user to use less syntax in ecss files * modify current ecss execution (evaluate EL expression and don't parse CSS anymore) * add a less compilator afterwards. Less compilation at build time or runtime ? For both of these 2 approaches, less compilation can be done built-time or execution time (need to investigate more to choose the right approach). If build time, richfaces-resources-maven-pluginwould be a candidate to execute El and less compilation.
