class CfgFunctions { class TAG { class Category { class myFunction {}; }; class OtherCategory { file = "My\Category\Path"; class myFunction {}; // file path will be <ROOT>\My\Category\Path\fn_myFunction.sqf"; }; class DataCategory { requiredAddons[] = { "A3_Data_F" }; // Optional requirements of CfgPatches classes. If some addons are missing, category functions will not be compiled. class myDataFunction {}; }; }; };
In this example, requiredAddons[] is being used as a Category attribute.
Contrary to that, the code seems to looking for a TAG attribute.
I dont know if the Documentation needs to be adjusted or the attribute doesnt work as intended.
I personally think it would be pretty cool if it would work for Categories as indicated in the biki.
