Hi,
As I couldn't find out if someone already build such a file here is (enclosed) my javascript tags file to enable javascript auto-completion ...
Alternative link : http://dl.yent.eu/em.js.tags
I extracted stuff from the W3C JS/DOM reference so it does not include jquery/dojo and such related tags (personally I don't need them) but since it is really easy to add other tags ...
Btw once more I really love geany's flexibility when it comes to customization ...
