[xwiki-users] Modifying macro.mv

Hello everyone, I am trying to modify the way the table of content (toc) macro behaves on xwiki, and I have a few questions concerning that. 1- Is there anywhere else the macro is defined besides in macros.mv? the changes I've made there did not show up on my xwiki instance after I restarted it. 2- what is the point of macros.txt? I was not able to find documentation for what xwiki is doing with that. 3- how would you recommend going about writing a new toc macro? I've been doing that using velocity on a dedicated xwiki page, but I'm not able to call some of the methods that toc macro is using, namely this call: #set ($tocData = ${tdoc.getTOC($init, $max, $numbered)}) Thanks!
