source: code/trunk/data/gui/scripts/NotificationLayer.lua @ 8729

Last change on this file since 8729 was 8729, checked in by rgrieder, 13 years ago

Merged unity_build branch back to trunk.

Features:

  • Implemented fully automatic build units to speed up compilation if requested
  • Added DOUT macro for quick debug output
  • Activated text colouring in the POSIX IOConsole
  • DeclareToluaInterface is not necessary anymore

Improvements:

  • Output levels now change appropriately when switch back and forth from dev mode
  • Log level for the file output is now also correct during startup
  • Removed some header file dependencies in core and tools to speed up compilation

no more file for command line options

  • Improved util::tribool by adapting some concepts from boost::tribool

Regressions:

  • It is not possible anymore to specify command line arguments in an extra file because we've got config values for that purpose.
  • Property svn:eol-style set to native
