Tables can be keyed on strings or numbers (amongst other things), so it can't afford to type-cast for you.

Ok, finally got it figured out... it seems that the only time that Lua doesn't take care of type casting for you is with table keys. this now works:

function ChangeColour( sTrig, sLine, wildcards )
  if colourcodes[ wildcards[2] ] ~= nil then
    colours[ tonumber( wildcards[1] ) ] = wildcards[2]
    ColourNote( colourcodes[ "@W" ],         "", "Colour "..wildcards[1].." set to ",
                colourcodes[ wildcards[2] ], "", wildcards[2] )
  else
    ColourNote( colourcodes[ "@W" ], "", wildcards[2].." is an invalid selection " )
  end
end
It is much easier to fight for one's ideals than to live up to them.

What pairs is that?

Can you tprint the wildcards?

I am trying to have a plugin with changeable display colours. I'm having a large problem with the colour changing script though, and I can't figure out why.

function ChangeColour( sTrig, sLine, wildcards )
  print( wildcards[1].." "..wildcards[2] )
  require "tprint"
  tprint( colours )
  tprint( colourcodes )
  print( ( colours[ wildcards[1] ] or "nil" ).." "..( colourcodes[ wildcards[2] or "" ] or "nil" ) )
  if colourcodes[ wildcards[2] ] ~= nil then
    colours[ wildcards[1] ] = wildcards[2]
  else
    ColourNote( colourcodes[ "%W" ], "", wildcards[2].." is an invalid selection " )
  end
end

all the prints are just for debugging this odd problem. Here is what happens when it is run:

1 @R
1="@G"
2="@W"
"@B"="#78BCFF"
"@C"="#5AFFFF"
"@m"="#BE32FF"
"@y"="#E3BF65"
"@W"="white"
"@M"="#FF5AFF"
"@b"="#5E5EFF"
"@c"="cyan"
"@R"="#FF5A5A"
"@G"="palegreen"
"@r"="red"
"@Y"="#FFFF5A"
"@w"="#E1E1E1"
"@g"="#2CCE2C"
nil #FF5A5A

somehow colours[1] is showing up as nil when printed using the wildcard, but not when going through the pairs.
