Tankbuster
This command can return a large array, often too large to be diag_log'd or hinted. At the time of writing, my game returned an array with 389 elements. The code below will ignore all the BI addons (they start with a3_) and writes the rest (ie, all your custom addons) to the RPT.
{if (! (["a3_", _x] call BIS_fnc_inString)) then {diag_log _x;} } forEach activatedAddons;
