   3 #  Generate node tree from verbose logfile
   4 #
   5 #  HOWTO USE
   6 #  =========
   7 #
   8 #  First of all, you need to recompile modules slideshow and canvas
   9 #  with VERBOSE=t set in the environment, and debug=t defined at the
  10 #  build tool command line. Then run your slideshow and redirect stdout
  11 #  to a file.
  12 #
  13 #  Then, call 'nodetree.sh trace-file > tree.ps' to generate a
  14 #  PostScript file for the AnimationNode tree generated during the show.
  15 #  Since these easily get pretty huge, use only one page, and try to
  16 #  limit the slide content (which have effects assigned, that is) to
  17 #  the bare minimum (to reproduce your bug, or whatever you need this
  18 #  for).
  19 #
  20 #  The generated output will have all nodes color-coded with their state
  21 #  at the point when the tree was dumped (see colors.sh for the color
  22 #  codes)
  23 #
  24 #  When looking for the mechanics that generate the relevant output,
  25 #  grep for the DEBUG_NODES_SHOWTREE macros in the slideshow source:
  26 #  Each such place dumps the current node tree to the trace output. Thus,
  27 #  if you need to check the tree state at other places or times, just add
  28 #  a DEBUG_NODES_SHOWTREE
