Heya,

I'm trying to figure out how I can write a logging plugint that doesn't just log the straight up text, but the colours as well in html format.

Any ideas on how I could start this project?

Go to the plugins page and look at the ANSI_Log plugin.

That does a similar thing. Rather than outputting ANSI codes, generate the appropriate HTML <font color=blah> stuff.

Problem is, I need to detect what colours are being used on the output, I.E.

You have recovered balance on all limbs.

is shown as green on black..

How would I see that via scripting?

That's why I suggested that plugin. Did you look at it?

Around here:


for line = firstline to lastline

  styles = GetLineInfo (line, 11)   ' how many styles

  '
  '  process all styles runs in this line
  ' 

  for style = 1 to styles
 
  '
  '  find text style (ANSI code)
  '
    
  fgcolour = GetStyleInfo (line, style, 14) ' RGB colour of style text

 '
 '  now do background
 '
 bgcolour = GetStyleInfo (line, style, 15) ' RGB colour of style background
   
'  ... and so on

  next
next


That gives you the RGB colours. Then simply use RGBColourToName to convert that to an HTML colour.

Erm, can't you just use the MC auto-html-logging feature?

Hah. Yep.

Sometimes we get into the 'working with what we have' aspect of the plugins that we forget that we actually do have this stuff already.

Unless he wants multiple logs, in which case he'll have to script it a bit.

Assuming for some reason the HTML logging doesn't work for you, another simpler approach these days it to write a plugin using Lua, that has a trigger. In Lua you can get a fourth argument to triggers that is a style list for the matching line. Then simply go through the style list and output the HTML. Pretty easy, and you can make the trigger include/exclude the lines you want.

This sort of thing would do the job, roughly:


function html_log (name, line, wildcards, styles)
  for _, v in styles do
    AppendToNotepad ("log", 
      '<span style="color: ',
      RGBColourToName (v.textcolour),
      '"; background: ',
      RGBColourToName (v.backcolour),
      '">',
      FixupHTML (v.text),
      '</span>');
  end -- for
  AppendToNotepad ("log", "\r\n");
end  -- function  html_log


Example output:


<span style="color: silver"; background: black">&lt;1000/1000hp 100/100m 110/110mv 2000/315816750xp&gt; </span>
