Log::Log4perl::Appender::File - Log to file
use Log::Log4perl::Appender::File;
my $app = Log::Log4perl::Appender::File->new(
filename => 'file.log',
mode => 'append',
autoflush => 1,
umask => 0222,
);
$file->log(message => "Log me\n");
This is a simple appender for writing to a file.
The log() method takes a single scalar. If a newline character
should terminate the message, it has to be added explicitely.
Upon destruction of the object, the filehandle to access the file is flushed and closed.
If you want to switch over to a different logfile, use the
file_switch($newfile) method which will first close the old
file handle and then open a one to the new file specified.
$mode is set to the
string "append". Will clobber the file
if set to "clobber". If it is "pipe", the file will be understood
as executable to pipe output to. Default mode is "append".
autoflush, if set to a true value, triggers flushing the data
out to the file on every call to log(). autoflush is on by default.
umask to use when creating the file, determining
the file's permission settings.
If set to 0222 (default), new
files will be created with rw-r--r-- permissions.
If set to 0000, new files will be created with rw-rw-rw- permissions.
If you're printing out Unicode strings, the output filehandle needs
to be set into :utf8 mode:
my $app = Log::Log4perl::Appender::File->new(
filename => 'file.log',
mode => 'append',
utf8 => 1,
);
To manipulate the output filehandle via binmode(), use the
binmode parameter:
my $app = Log::Log4perl::Appender::File->new(
filename => 'file.log',
mode => 'append',
binmode => ":utf8",
);
A setting of ":utf8" for binmode is equivalent to specifying
the utf8 option (see above).
Design and implementation of this module has been greatly inspired by
Dave Rolsky's Log::Dispatch appender framework.
