Hi world, As you know, we are using both YUI and jquery javascript libraries in Koha. That's too much ! I think jquiry-ui (http://jqueryui.com) is good enough to decide to get rid of YUI. Pro: * jquery much more developed * yui & webdev have problems working together * a lot of informations are available for jquery, including tutorials and books * http://jqueryui.com/docs/Theming/API seems much more clear & easy to use to me than yui css (is it just me ?) * jqueryui comes with (a themable) complete set of icons Cons: ? (Anyone want to argue ?) So, I propose the following roadmap : * new templates should be developed using jquery, not yui * 3.4 would still have both * in 3.6, we get rid of yui Other question : should we have jquery code inside koha (and thus having to take care of the updates) or should we use an external source ? (does this exist ? for yui it does, see yuipath syspref in koha) -- Paul POULAIN http://www.biblibre.com Expert en Logiciels Libres pour l'info-doc Tel : (33) 4 91 81 35 08
