Logging

Quarkdown features ways to log content to standard channels.

• .log {message} logs to stdout at info level (-Dloglevel=info or below);
• .debug {message} logs to stdout at debug level (-Dloglevel=debug or below);
• .error {message} throws a runtime error, which is then handled according to the error manager:
  • By default, the error message is logged to stderr (-Dloglevel=error or below) and an error box is shown in the document;
  • If the program was executed in strict mode (--strict), a full stack trace is logged to stderr and the program exits.
