Lau Help - How to?

I currently use Nexus on Achaea; I have Mush downloaded, but I'm an uber noob when it comes to coding clients. Nexus is OK, but not really all that powerful imo. The only things I really want to know how to do are:

-Set up a color code system for enemies, and possibly color code citizens of cities.

-Learn how to use paths or have an auto walk system set up (think paths on Mush are for only python)

-Have an auto sipper system(been reading about this in another thread)

-Learn how to effectivly gag and replace text for combat messages.

The rest I can pretty much wing, but if anyone could help me, give me some tips, or point me in the right direction, I would be most grateful and thanks ahead of time for any help.

First, let's get the language name right. In another thread you also referred to it as "Lau". It is Lua, not Lau.

• Colour code system? A trigger with a regexp can colour words. Some people have pulled in lengthy word lists from a variable, so a single regexp can match many words.
  
• The auto-walk system basically remembers a path you have walked once, and can turn it into a speedwalk. This can be done without scripting.
  
• I think there are a few posts about auto-sippers, try searching the forum.
  
• You can omit combat messages from output, and then do a Note or ColourNote in a script to replace with something else. Make sure you either use a script file, or send to "Script (after omit)".
