Message:	[quote=Jdiddleymspot] Hi, I don't have a clue about triggers or anything to do with how to code on MUSHclient. Basically, what I want is for when a PC or NPC description is displayed on screen, it will put his/her/its name in brackets after the description. How do I do this? Thanks for the help!

You can't directly put tables into variables. However it is easy enough with serialization:

http://www.gammon.com.au/forum/?id=4960

For example with this test data:



-- example table - in practice you would make an alias to add them

names = {
 ["a funny looking clown"] = "Tom",
 ["a sleepy fellow"] = "John",
 ["a pretty girl"] = "Sarah",

-- more here

}

Put this into the "on world save" callback:


require "serialize"

SetVariable ("saved_names", "names = " .. serialize.save_simple (names))

Now if you look at the (MUSHclient) variable "saved_names" (in the variables configuration dialog) you see this:


names = {
  ["a sleepy fellow"] = "John",
  ["a pretty girl"] = "Sarah",
  ["a funny looking clown"] = "Tom",
  }

This will now be saved as part of the world file, whenever you save that.

Next time (using the "world open" script callback) you put the names back like this:


assert (loadstring (GetVariable ("saved_names") or "")) ()

That converts the "string" table into an actual table.

So much for saving and loading.

Now to use in the trigger. Do the following whenever the list of names changes:


function getNames ()
 local t = {}
 for k, v in pairs (names) do
   table.insert (t, k)
 end
 SetVariable ("names_match", table.concat (t, "|"))
end

I use a second table here to convert the descriptions/names into a numerically-keyed table of just the descriptions. Then table.concat puts a "|" between each one.

Thus now names_match is:


a sleepy fellow|a pretty girl|a funny looking clown

Finally we can use the variable names_match in the trigger by putting it there with "expand variables" checked. Also note the use of the "!" which stops MUSHclient trying to put a backslash in front of the "|" characters ...


<triggers>
  <trigger
   enabled="y"
   expand_variables="y"
   ignore_case="y"
   match="^(.*?)(@!names_match)(.*?)$"
   omit_from_output="y"
   regexp="y"
   send_to="14"
   sequence="110"
  >

-- show each style in its original colour

for i, style in ipairs (TriggerStyleRuns) do
  ColourTell (RGBColourToName (style.textcolour), RGBColourToName (style.backcolour), style.text)

  -- if person's description, append their name
  if style.text == "%2" then
    ColourTell ("white", "", " (" ..
      (names ["%2"] or "unknown") ..
       ")")
   end -- if
end

Note ""  -- start new line

  </trigger>
