Inside Lua regular expressions you can "escape" the square brackets by putting % in front of them. eg. %[

that would mean something like this?


if not string.match (line, "^%[ [%a%d]%]: ")



"match bracket space [all.letters all.digits] bracket colon space"


did i got it a bit right?

[EDIT] nope, i didn't. got the title to show, but not the items worn. :(

Can you give more information please. Not just quote tiny parts of what you are trying to match on. So you've posted the alias. Now post the entire thing (lines) from the MUD you are trying to match on.

to drag the window around, does it has to be a plugin?
i know i like it when my inv and 2 backpacks are resizing at will on my right side of the window, because they see eachother.

but i would like to drag my equipment window around, which is created according to the inv alias.
cause it's size is stationary.

i read about the dragging, but i couldn't find the part where i can just copy/paste a specific part into my alias.

I need some help trying to figure out how to do this. I've searched this forum up and down using words I thought would relate to what I'm trying to do.

I want to use this code...


local battle = {}
local max_width = WindowTextWidth (win, font, "Battle")

-- loop until end of Battle text

while true do
  local line, wildcards, styles = wait.match ("*")

  -- see if end of inventory

  if string.match (line, "&amp;lt;Battle&amp;gt; Input command for *. +attack +item +switch +run") then
    break
  end -- if

  -- save battle line
  table.insert (battle, styles)



and make it break up multiple values on each line that are separated by the pipe character so I can turn them into variables and / or table values

For instance,

|---oxooso-----------|----------xoxoxs----|
|Curtis              |                    |
|Fang                |Rat                 |
|--------------------|--------------------|
|Joe                 |                    |
|Jason               |Bird                |
|--------------------|--------------------|
<Battle> Input command for Fang. +attack +item +switch +run 



I want to be able to turn each of these "table cells" into an actual table value so I can use them later (by displaying them in a mini window.

To explain the output above, Curtis owns a creature called Fang. Fang is a Rat. Joe owns a creature called Jason. Jason is a Bird.


Is there a simple way to do this, or should I follow the guidance on FAQ #37 and create multiple triggers to accomplish this?

In this case I simply need to have six seperate table items that I can refer to. I might consider using subtables to put "Fang" and "Rat" under "Curtis" and same with Joe.

This data gets refreshed during each turn where the "creature" might change.

All this stuff follows the basic idea in FAQ 37. You find a starting pattern (eg. "Your inventory is:"). You capture lines until an end pattern (eg. "End of inventory"). If there is no specific end pattern you just capture lines "that look like inventory".

In your case your starting line seems to be some "=" signs followed by one or more of O, X, S and so on. So that should be easy.

And the end seems to start with "<Battle>". So that's easy too.

As for the middle lines, excepting the hyphen lines, you should be able to break up the data, quite possibly by column position, trim trailing spaces, convert to numbers where appropriate, and save into a table.

I've already been able to put the data into a miniwindow, but I haven't quite been able to figure out how to turn the data into variables. I have no programming experience whatsoever (except formula building in Excel, which doesn't count), so I'm pretty much running with my head cut off trying to figure this out.

I'm the type of person who needs to understand every little thing about something to get that "aha!" moment where everything just clicks.




for instance,

while true do
  local line, wildcards, styles = wait.match ("*", trigger_flag.OmitFromOutput)


I understand that "while true do" is a conditional statement.
I understand that "local line" is creating a variable called "line".
I also understand what " wait.match ("*", trigger_flag.OmitFromOutput)" is doing

but I don't really understand why/what the "wildcards, styles" part is doing here.


And although I really want to understand how that works, I REALLY want to know how to brake up a line of output into variables without creating a second trigger, and resorting to wildcards.

It will help to read the Programming in Lua book. Quite a nice read.

Anyway, functions in Lua can return multiple things.

So for a line like this:


line, wildcards, styles = wait.match (...)


We assume that wait.match is returning 3 things. And from the names we guess that we are getting back the matching line, any wildcards, and the style runs (the colours). There is only one wildcard in this particular case, so wildcards [1] and 'line' are going to be the same thing.

Your data looked pretty positional to me (ie. fixed-width) so the simplest thing would be to take "line" and just break it up. Say the first part was 20 characters long (after the "|" character) you might say:


mobname = string.sub (line, 2, 20)


Where 2 is the start column, and 20 is the end column.

And so on for the other stuff.

I have had quite some succes in creating several windows for different containers in Aardwolf.

but i noticed a different problem, when storing huge amounts of potions in a single bag.

I was given the following string.match to capture the amounts of a single named item

 if not string.match (line, "^%([ %d]%d%) ") then


But it only works when it's a 2 digit amount:

(46) Potion


when i get to a 3 digit amount:

(101) Potion

then the window dissapears.

Any idea's?

Would indeed match 2 digit numbers. Maybe:
