Libinsane logs

Libinsane

By default, all logs from libinsane go to stderr. This may not be what you want (debug logs are very verbose).

This can be changed by defining a callback to handle logs using functions from log.h.

Libinsane-gobject

You have to create an object implementing the interface Libinsane.Logger and pass it to libinsane_register_loggger().

Example 1

from gi.repository import Libinsane  # noqa: E402


class ExampleLogger(GObject.GObject, Libinsane.Logger):
    def do_log(self, lvl, msg):
        if lvl <= Libinsane.LogLevel.WARNING:
            return
        print("{}: {}".format(lvl.value_nick, msg))


def main():
    Libinsane.register_logger(ExampleLogger())

Example 2

class ExampleLogger(GObject.GObject, Libinsane.Logger):
    def do_log(self, lvl, msg):
        if lvl <= Libinsane.LogLevel.INFO:
            return
        print("{}: {}".format(lvl.value_nick, msg))
        sys.stdout.flush()

    Libinsane.register_logger(ExampleLogger())
