Instance specific directory defined configuration 2. app's template specific directory, eg. addressbook/templates/$template/images/navbar.png 3. app's default image directory, eg. addressbook/templates/default/images 4. templates image directory, eg. phpgwapi/idots/images or for newer templates $template/images 5. API default image directory phpgwapi/templates/default/images Images lower down in above hierarchy are NOT to be copied to more specific directories, unless they should be overwritten! Automatic loading of CSS styles: ------------------------------- a) theme from template, eg. phpgapi/templates/idots/css/idots.css b) etemplate/templates/default/(app|etemplate2).css (only for eTemplate applications) c) either: - apps template specific app.css eg. $appname/templates/$template/app.css or - apps default $appname/templates/default/app.css CSS preprocessor less: ===================== More information about syntax can be found under http://lesscss.org/ EGroupware requires at least version 1.4 as we use @include (require) syntax to fetch just definitions from phpgwapi/templates/default/def_*.less. Currently commiter is responsible to generate all CSS files depending on a change .less file and also to made changes in .less file not .css file, if a .less file exits. One way to do so is automatic with NetBeans 7.4: ----------------------------------------------- 1. install a current node.js and npm (node package manager) follwoing this tutorial https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager a) for Mac OS X eg. use: port install node npm You need to symlink node to default location: ln -s /opt/local/bin/node /usr/bin/ b) Ubuntu 13.10 still includes too old node version (at least for less v. 1.5.0), so follow above tutorial using Chris Lea's node repository 2. install lessc via npm: npm install -g less 3. Got to: NetBeans preferences >> Miscellanceous >> CSS Preprocessor and set: Less path: /usr/bin/lessc or /opt/local/bin/lessc depending on your way of installing lessc Uncheck "Generate extra information (debug)" 4. Open EGroupware project configuration in NetBeans (right click on project >> properties) >> CSS Preprocessor >> LESS - check "Compile LESS Files on Save" - Watch: change default "css/" "less/" to "." "." (generate css file in same directory) - no compile options used currently --> after that NetBeans compiles LESS files automatic to CSS files (you have to commit both!)
