Logging

All logging levels are defined in jsb_log_severity.def.h:

  • VeryVerbose: very trivial messages (omitted by default even if JSB_DEBUG is on)
  • Verbose: trivial messges (will not output in the editor panel)
  • Debug: not important, also used by console.debug
  • Info: general level, also used by console.info
  • Log: used by console.log
  • Trace: used by console.trace, with stacktrace anyway
  • Warning: used by console.warn
  • Error: used by console.error, unexpected but not critical errors
  • Assert: used by console.assert, print only if assertion failed
  • Fatal: critial errors

By default, VeryVerbose is omitted at compile-time. You can change it in jsb.config.h by setting JSB_MIN_LOG_LEVEL to VeryVerbose.
Verbose messages will be displayed only if the --verbose flag is set on the command line for the godot executable, and they will appear exclusively in the console (launch from IDE, or start godot from the command line).
