Hi,
I'm trying to move mud minimap to separate miniwindow. This is for Nodeka mud and the problem is that the start and the end of map cannot be triggered by some text pattern. However, I have found out that Nodeka sends some nonprintable chars at the beggining and end of the map.

I have created this plugin so far:


<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE muclient>
<!-- Saved on Monday, May 18, 2009, 8:38 PM -->
<!-- MuClient version 4.40 -->

map_line      = false
map           = ""

    map = map .. packet
    packet_left = ""
  elseif not map_line and map_start_ind and map_end_ind then      -- whole map inside of 1 packet
    map = string.sub(packet, map_start_ind, map_end_ind)
    packet_left = string.sub(packet, 1, map_start_ind)..string.sub(packet, map_end_ind)

    UpdateMap()
  else                                                    -- corner cases - more maps in one packet etc.
    packet_left = packet
  end
  return packet_left
end

function UpdateMap()
  AnsiNote(map)
  map=""
end

map_start_reg and map_end_reg are the regular expressions that mark the beginning and the end of map. As you can see, they are nonprintable chars. AFAIK I can match nonprintable chars only by regexp and only from raw packets, which complicates the situation. This plugin works, but I would like to change the UpdateMap function to draw the map into the miniwindow. The problem is that map string contains raw text with ANSI escapes. Is there any good way to write this text with colors into miniwindow? I can create my own function in Lua to convert the ANSI into the styled text with the help of regexp, but it might be both quite complex and the result might slow down the things as well.

Sorry for not escaping the patterns for the forums.
map_start_reg and map_end_reg should have two \ everywhere, otherwise the plugin won't work. I'm using the MUSHClient from WINE and working with clipboard is tricky sometimes :)

BTW MUSHClient under WINE has some problems but I guess it doesn't belong to this thread.
