Description

Users of MAFW can enable the display of log and informational messages selectively in run-time. To do so you need to invoke mafw_log_init(), which takes a string describing what levels of messages to log; others are all disabled. You can override this compile-time specification by setting the $MAFW_LOG environment variable.

The specification string is like "[domain]:level[,[domain]:level]*", where `domain' is the log_domain argument of g_log, and `level' is either "ERROR", "CRITICAL", "WARNING", "MESSAGE", "INFO", "DEBUG", "ALL", "PRINT" or "-" (lettercase is not taken into account) telling the minimum required urgency of messages to be logged (ie. don't log less important messages).

"-" means don't log anything from that domain. If `domain' is "default" `level' applies to all messages for which G_LOG_DOMAIN wasn't defined. Otherwise if the `domain' part is empty `level' will apply to domains not specifically mentioned in the string.

All possible values of `level' except "ALL" and "PRINT" makes g_print() silent. If `level' is "ALL" the domain is effectively ignored by the filtering mechanism (ie. it's processing is left as it was). "PRINT" is like "-", but leaves g_print() enabled.

Some examples:

# silence everything
MAFW_LOG=":-" ./app
# silence 'foo'
MAFW_LOG="foo:-" ./app
# only mafw messages less important than message
MAFW_LOG="mafw:warning" ./app
# all from mafw-dbus
MAFW_LOG="mafw-dbus:debug" ./app
