- PyGRASS message interface
- =========================
- The PyGRASS message interface is a fast and exit-safe
- interface to the `GRASS C-library message functions <http://grass.osgeo.org/programming7/gis_2error_8c.html>`_.
- This class implements a fast and exit-safe interface to the GRASS
- C-library message functions like: G_message(), G_warning(),
- G_important_message(), G_verbose_message(), G_percent() and G_debug().
- Usage:
- >>> msgr = Messenger()
- >>> msgr.debug(0, "debug 0")
- >>> msgr.verbose("verbose message")
- >>> msgr.message("message")
- >>> msgr.important("important message")
- >>> msgr.percent(1, 1, 1)
- >>> msgr.warning("Ohh")
- >>> msgr.error("Ohh no")
- >>> msgr = Messenger()
- >>> msgr.fatal("Ohh no no no!")
- Traceback (most recent call last):
- File "__init__.py", line 239, in fatal
- sys.exit(1)
- SystemExit: 1
- >>> msgr = Messenger(raise_on_error=True)
- >>> msgr.fatal("Ohh no no no!")
- Traceback (most recent call last):
- File "__init__.py", line 241, in fatal
- raise FatalError(message)
- FatalError: Ohh no no no!
- >>> msgr = Messenger(raise_on_error=True)
- >>> msgr.set_raise_on_error(False)
- >>> msgr.fatal("Ohh no no no!")
- Traceback (most recent call last):
- File "__init__.py", line 239, in fatal
- sys.exit(1)
- SystemExit: 1
- >>> msgr = Messenger(raise_on_error=False)
- >>> msgr.set_raise_on_error(True)
- >>> msgr.fatal("Ohh no no no!")
- Traceback (most recent call last):
- File "__init__.py", line 241, in fatal
- raise FatalError(message)
- FatalError: Ohh no no no!
