Mail::SpamAssassin::LoUser(Contributed Perl DocumMail::SpamAssassin::Logger(3)
NAME
       Mail::SpamAssassin::Logger - SpamAssassin logging module
SYNOPSIS
         use Mail::SpamAssassin::Logger;
         $SIG{__WARN__} = sub {
           log_message("warn", $_[0]);
         };
         $SIG{__DIE__} = sub {
           log_message("error", $_[0])  if !$^S;
         };
METHODS
       add_facilities(facilities)
           Enable debug logging for specific facilities.  Each facility is the
           area of code to debug.  Facilities can be specified as a hash
           reference (the key names are used), an array reference, an array,
           or a comma-separated scalar string. Facility names are case-
           sensitive.
           If "all" is listed, then all debug facilities are implicitly
           enabled, except for those explicitly disabled.  A facility name may
           be preceded by a "no" (case-insensitive), which explicitly disables
           it, overriding the "all".  For example: all,norules,noconfig,nodcc.
           When facility names are given as an ordered list (array or scalar,
           not a hash), the last entry applies, e.g. 'nodcc,dcc,dcc,noddc' is
           equivalent to 'nodcc'.  Note that currently no facility name starts
           with a "no", it is advised to keep this practice with newly added
           facility names to make life easier.
           Higher priority informational messages that are suitable for
           logging in normal circumstances are available with an area of
           "info".  Some very verbose messages require the facility to be
           specifically enabled (see "would_log" below).
       log_message($level, @message)
           Log a message at a specific level.  Levels are specified as
           strings: "warn", "error", "info", and "dbg".  The first element of
           the message must be prefixed with a facility name followed directly
           by a colon.
       dbg("facility: message")
           This is used for all low priority debugging messages.
       info("facility: message")
           This is used for informational messages indicating a normal, but
           significant, condition.  This should be infrequently called.  These
           messages are typically logged when SpamAssassin is run as a daemon.
       add(method => 'syslog', socket => $socket, facility => $facility)
           "socket" is the type the syslog ("unix" or "inet").  "facility" is
           the syslog facility (typically "mail").
       add(method => 'file', filename => $file)
           "filename" is the name of the log file.
       add(method => 'stderr')
           No options are needed for stderr logging, just don't close stderr
           first.
       remove(method)
           Remove a logging method.  Only the method name needs to be passed
           as a scalar.
       would_log($level, $facility)
           Returns false if a message at the given level and with the given
           facility would not be logged.  Returns 1 if a message at a given
           level and facility would be logged normally.  Returns 2 if the
           facility was specifically enabled.
           The facility argument is optional.
       close_log()
           Close all logs.
