NAME
Log::Dispatch::File - Object for logging to files
SYNOPSIS
use Log::Dispatch::File;
my $file = Log::Dispatch::File->new( name => 'file1',
min_level => 'info',
filename => 'Somefile.log',
mode => 'append' );
$file->log( level => 'emerg', message => "I've fallen and I can't get up\n" );
DESCRIPTION
This module provides a simple object for logging to files under the Log::Dispatch::* sys-
tem.
METHODS
* new(%p)
This method takes a hash of parameters. The following options are valid:
* name ($)
The name of the object (not the filename!). Required.
* min_level ($)
The minimum logging level this object will accept. See the Log::Dispatch doc-
umentation on Log Levels for more information. Required.
* max_level ($)
The maximum logging level this obejct will accept. See the Log::Dispatch doc-
umentation on Log Levels for more information. This is not required. By
default the maximum is the highest possible level (which means functionally
that the object has no maximum).
* filename ($)
The filename to be opened for writing.
* mode ($)
The mode the file should be opened with. Valid options are 'write', '>',
'append', '>>', or the relevant constants from Fcntl. The default is 'write'.
* close_after_write ($)
Whether or not the file should be closed after each write. This defaults to
false.
If this is true, then the mode will aways be append, so that the file is not
re-written for each new message.
* autoflush ($)
Whether or not the file should be autoflushed. This defaults to true.
* permissions ($)
If the file does not already exist, the permissions that it should be created
with. Optional. The argument passed must be a valid octal value, such as
0600 or the constants available from Fcntl, like S_IRUSR|S_IWUSR.
See "chmod" in perlfunc for more on potential traps when passing octal values
around. Most importantly, remember that if you pass a string that looks like
an octal value, like this:
my $mode = '0644';
Then the resulting file will end up with permissions like this:
--w----r-T
which is probably not what you want.
* callbacks( \& or [ \&, \&, ... ] )
This parameter may be a single subroutine reference or an array reference of
subroutine references. These callbacks will be called in the order they are
given and passed a hash containing the following keys:
( message => $log_message, level => $log_level )
The callbacks are expected to modify the message and then return a single
scalar containing that modified message. These callbacks will be called when
either the "log" or "log_to" methods are called and will only be applied to a
given message once.
* log_message( message => $ )
Sends a message to the appropriate output. Generally this shouldn't be called
directly but should be called through the "log()" method (in Log::Dispatch::Output).
