Yes, I found that myself already:

var st: gtksource.Style = gtksource.getStyle(style, "text")
assert(st != nil)
objectGet(st, "foreground", addr str, nil)

This way I can access the default text foreground and background
colors. Unfortunately it took me some hours to find that...

But it would be nice if we could use these colors

  <!-- Global Settings -->
  <style name="current-line"                background="#eeeeec"/>
  <style name="current-line-number"         background="#eeeeec"/>
  <style name="draw-spaces"                 foreground="#babdb6"/>
  <style name="background-pattern"          background="#f3f3f3"/>

  <!-- Bracket Matching -->
  <style name="bracket-match"               foreground="white" background="gray" bold="true"/>
  <style name="bracket-mismatch"            foreground="white" background="red" bold="true"/>

  <!-- Right Margin -->
  <style name="right-margin"                foreground="#000000" background="#000000"/>

  <!-- Search Matching -->
  <style name="search-match"                background="yellow"/>


in the same way as these starting with :def

  <!-- Comments -->
  <style name="def:comment"                 foreground="blue"/>


Seems not to work, in the *.lang files the map-to works not with the "Global Settings".
