NAME
    Log::Dispatch::File - Object for logging to files

VERSION
    version 2.70

SYNOPSIS
      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");

DESCRIPTION
    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 Log::Dispatch::File::Locked output instead, which allows
    multiple processes to safely share a single file.

CONSTRUCTOR
    The constructor takes the following parameters in addition to the standard parameters documented
    in Log::Dispatch::Output:

    *   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 "syswrite" in perlfunc(), as opposed to "print" in
        perlfunc(). This defaults to false. The usual caveats and warnings as documented in
        "syswrite" in perlfunc 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 "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.
