NAME

File::MMagic::XS - Guess File Type With XS (a la mod_mime_magic)

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);

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!

METHODS

new(%args)

Creates a new File::MMagic::XS object.

If you specify the 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.

parse_magic_file($file)

Read and parse a magic file, as used by Apache2.

get_mime($file)

Inspects the file specified by $file and returns a MIME type if possible. If no matching MIME type is found, then undef is returned.

fsmagic($file)

Inspects a file and returns a MIME type using inode information only. The contents of the file is not inspected.

fhmagic($fh)

Inspects a file handle and returns a mime string by reading the contents of the file handle.

ascmagic($file)

Inspects a piece of data (assuming it's not binary data), and attempts to determine the file type.

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

error()

Returns the last error string.
