2006-11-21 Emmanuele Bassi <ebassi@openedhand.com> * configure.ac: Enable debug messages also when --enable-debug is set to "minimum". * clutter/Makefile.am: * clutter/clutter-debug.h: Move all debugging macros inside this private header; make all debug macros depend on the CLUTTER_ENABLE_DEBUG compile time define, controlled by the --enable-debug configure switch; add G_LOG_DOMAIN define. * clutter/clutter-main.c: Clean up the debug stuff; add command line argument parsing using GOption; the debug messages now are triggered like this: CLUTTER_DEBUG=section:section:... clutter-app or like this: clutter-app --clutter-debug=section:section:... where "section" is one of the sections listed in clutter-main.c, or "all", for all sections; each section is bound to a flag, which can be used to define a domain when adding a debug note using the CLUTTER_NOTE() macro; the old CLUTTER_DBG() macro is just a wrapper around that, under the CLUTTER_DEBUG_MISC domain; CLUTTER_NOTE() is used like this: CLUTTER_NOTE (DOMAIN, log-function); where log function is g_printerr(), g_message(), g_warning(), g_critical() or directly g_log() - for instance: CLUTTER_NOTE (PANGO, g_warning ("Cache miss: %d", glyph)); will print the warning only if the "pango" flag has been set to the CLUTTER_DEBUG envvar or passed to the --clutter-debug command line argument. similar to CLUTTER_SHOW_FPS, there's also the --clutter-show-fps command line switch; also, the --display and --screen command line switches have been added: the first overrides the DISPLAY envvar and the second controls the X screen used by Clutter to get the root window on the display. * clutter/clutter-main.h: * clutter/clutter-main.c: Add extended support for GOption in Clutter; use clutter_init_with_args() to let Clutter parse your own command line arguments; use instead clutter_get_option_group() to get the GOptionGroup used by Clutter if you want to do the parsing yourself with g_option_context_parse(). The init sequence has been verified, updated and moved into common functions where possible. * clutter/pango/pangoclutter-render.c: * clutter/*.c: Include "clutter-debug.h" where needed; use CLUTTER_NOTE() instead of CLUTTER_DBG(). * examples/super-oh.c: Use the new clutter_init_with_args() function, and add a --num-hands command line switch to the SuperOH example code controlling the number of hands at runtime.
