Log::Dispatch::File - Object for logging to files
version 2.70
use Log::Dispatch;
my $log = Log::Dispatch->new(
outputs => [
[
'File',
min_level => 'info',
filename => 'Somefile.log',
mode => '>>',
newline => 1
]
],
);
$log->emerg("I've fallen and I can't get up");
This module provides a simple object for logging to files under the
Log::Dispatch::* system.
Note that a newline will not be added automatically at the end of a message
by default. To do that, pass newline => 1.
NOTE: If you are writing to a single log file from multiple processes, the
log output may become interleaved and garbled. Use the
the Log::Dispatch::File::Locked manpage output instead, which allows multiple processes
to safely share a single file.
The constructor takes the following parameters in addition to the standard
parameters documented in the Log::Dispatch::Output manpage:
- filename ($)
The filename to be opened for writing.
- mode ($)
The mode the file should be opened with. Valid options are 'write',
'>', 'append', '>>', or the relevant constants from Fcntl. The
default is 'write'.
- binmode ($)
A layer name to be passed to binmode, like ``:encoding(UTF-8)'' or ``:raw''.
- close_after_write ($)
Whether or not the file should be closed after each write. This
defaults to false.
If this is true, then the mode will always be append, so that the file is not
re-written for each new message.
- lazy_open ($)
Whether or not the file should be opened only on first write. This defaults to
false.
- autoflush ($)
Whether or not the file should be autoflushed. This defaults to true.
- syswrite ($)
Whether or not to perform the write using perlfunc/syswrite(),
as opposed to perlfunc/print(). This defaults to false.
The usual caveats and warnings as documented in perlfunc/syswrite apply.
- 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 perlfunc/chmod 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.
