 You can hook a function like "AddonName:Function()" by replaceing the ":" with a ".".
 For example if the below code is from someone's addon:
+ function AnAddon.Module:FuncName(per1,per2)
-<div style="max-height: 200px; overflow: auto; border: 2px solid black; padding: 0.5em; margin-left: 0.5em">
+   -- Things happen here...
-<pre style="margin: 0; border: 0"><nowiki>
+ end;
-function AnAddon.Module:FuncName(per1,per2)
-	-- Things happen here...
-end;
-</nowiki></pre></div>
 You can use the following to pre-hook it:
+ local original_AnAddon_Module_FuncName = AnAddon.Module.FuncName; -- Store the original function encase you want to use it.
-<div style="max-height: 200px; overflow: auto; border: 2px solid black; padding: 0.5em; margin-left: 0.5em">
+ function AnAddon.Module:FuncName(per1,per2) -- This is the new function to overwrite the original one
-<pre style="margin: 0; border: 0"><nowiki>
+   if (per1 > 10) then
-local original_AnAddon_Module_FuncName = AnAddon.Module.FuncName; -- Store the original function encase you want to use it.
+     ChatFrame1:AddMessage(tostring(per1));
+   else
-function AnAddon.Module:FuncName(per1,per2) -- This is the new function to overwrite the original one
+     original_AnAddon_Module_FuncName(self,...); -- Calls original function like nothing happened
-	if (per1 > 10) then
+   end;
-		ChatFrame1:AddMessage(tostring(per1));
+ end;
-	else
-		original_AnAddon_Module_FuncName(self,...); -- Calls original function like nothing happened
-	end;
-end;
-</nowiki></pre></div>
 Assuming per1 is a number greater than 10 then per2 will be printed and if per1 isn't then the original function will run.
