=head1 NAME
File::MMagic::XS - Guess File Type With XS (a la mod_mime_magic)
=head1 SYNOPSIS
use File::MMagic::XS;
my $m = File::MMagic::XS->new();
$m = File::MMagic::XS->new('/etc/magic'); # use external magic file
my $mime = $m->get_mime($file);
# use File::MMagic compatible interface
use File::MMagic::XS qw(:compat);
my $m = File::MMagic::XS->new();
$m->checktype_filename($file);
=head1 DESCRIPTION
This is a port of Apache2 mod_mime_magic.c in Perl, written in XS with the
aim of being efficient and fast, especially for applications that need to be
run for an extended amount of time.
There is a compatibility layer for File::MMagic. you can specify :compat
when importing the module
use File::MMagic::XS qw(:compat);
And then the following methods are going to be available from File::MMagic::XS:
checktype_filename
checktype_filehandle
checktype_contents
addMagicEntry
Currently this software is in beta. If you have suggestions/recommendations
about the interface or anything else, now is your chance to send them!
=head1 METHODS
=head2 new(%args)
Creates a new File::MMagic::XS object.
If you specify the C<file> argument, then File::MMagic::XS will load magic
definitions from the specified file. If unspecified, it will use the magic
file that will be installed under File/MMagic/ directory.
=head2 clone()
Clones an existing File::MMagic::XS object.
=head2 parse_magic_file($file)
Read and parse a magic file, as used by Apache2.
=head2 get_mime($file)
Inspects the file specified by C<$file> and returns a MIME type if possible.
If no matching MIME type is found, then undef is returned.
=head2 fsmagic($file)
Inspects a file and returns a MIME type using inode information only. The
contents of the file is not inspected.
=head2 fhmagic($fh)
Inspects a file handle and returns a mime string by reading the contents
of the file handle.
=head2 ascmagic($file)
Inspects a piece of data (assuming it's not binary data), and attempts to
determine the file type.
=head2 bufmagic($scalar)
Inspects a scalar buffer, and attempts to determine the file type
=head2 add_magic($magic_line)
Adds a new magic entry to the object. The format of $magic_line is the same
as magic(5) file. This allows you to add custom magic entries at run time
=head2 add_file_ext($ext, $mime)
Adds a new file extension to MIME mapping. This is used as a fallback method
to determining MIME types.
my $magic = File::MMagic::XS->new;
$magic->add_file_ext('t', 'text/perl-test');
my $mime = $magic->get_mime('t/01-sanity.t');
This will make get_mime() return 'text/perl-test'.
=head2 error()
Returns the last error string.
