Automatic image loading order:
|
|
|
|
|
=============================
|
|
|
|
|
1. 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
|
2013-11-12 12:43:13 +01:00
|
|
|
b) etemplate/templates/default/(app|etemplate2).css (only for eTemplate applications)
|
2013-11-12 12:26:06 +01:00
|
|
|
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!)
|
