.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module provides a simple object for logging to files under the
Log::Dispatch::* system.
.PP
Note that a newline will \fInot\fR be added automatically at the end of a message
by default. To do that, pass \f(CW\*(C`newline => 1\*(C'\fR.
.SH "CONSTRUCTOR"
.IX Header "CONSTRUCTOR"
The constructor takes the following parameters in addition to the standard
parameters documented in Log::Dispatch::Output:
.IP "\(bu" 4
filename ($)
.Sp
The filename to be opened for writing.
.IP "\(bu" 4
mode ($)
.Sp
The mode the file should be opened with. Valid options are 'write',
\&'>', 'append', '>>', or the relevant constants from Fcntl. The
default is 'write'.
.IP "\(bu" 4
binmode ($)
.Sp
A layer name to be passed to binmode, like \*(L":encoding(\s-1UTF\-8\s0)\*(R" or \*(L":raw\*(R".
.IP "\(bu" 4
close_after_write ($)
.Sp
Whether or not the file should be closed after each write. This
defaults to false.
.Sp
If this is true, then the mode will always be append, so that the file is not
re-written for each new message.
.IP "\(bu" 4
autoflush ($)
.Sp
Whether or not the file should be autoflushed. This defaults to true.
.IP "\(bu" 4
syswrite ($)
.Sp
Whether or not to perform the write using \*(L"syswrite\*(R" in perlfunc(),
as opposed to \*(L"print\*(R" in perlfunc(). This defaults to false.
The usual caveats and warnings as documented in \*(L"syswrite\*(R" in perlfunc apply.
.IP "\(bu" 4
permissions ($)
.Sp
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.
.Sp
See \*(L"chmod\*(R" 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:
.Sp
.Vb 1
\& my $mode = \*(Aq0644\*(Aq;
.Ve
.Sp
Then the resulting file will end up with permissions like this:
.Sp
.Vb 1
\& \-\-w\-\-\-\-r\-T
.Ve
.Sp
which is probably not what you want.
