grappa allows a small level of configuration to customize behavior and error reporting.


  • use_colors bool - Defaults to True - Enables/disables showing ANSI colored text in error exception messages.
  • show_code bool - Defaults to True - Enables/disables showing code fragment with the line that originally caused the error in the exception message.
  • debug bool - Defaults to False - Enables internal debug mode. This would output a lot of stuff into stdout. Only intended to be used for grappa developers.

New configuration option can be added in the future


import grappa

# Disables code output in error messages
grappa.config.show_code = False
# Enables colored error messages
grappa.config.use_colors = True
