File::MMagic::XS - Guess File Type With XS (a la mod_mime_magic)
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);
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!
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.
Clones an existing File::MMagic::XS object.
Read and parse a magic file, as used by Apache2.
Inspects the file specified by $file and returns a MIME type if possible. If no matching MIME type is found, then undef is returned.
Inspects a file and returns a MIME type using inode information only. The contents of the file is not inspected.
Inspects a file handle and returns a mime string by reading the contents of the file handle.
Inspects a piece of data (assuming it's not binary data), and attempts to determine the file type.
Inspects a scalar buffer, and attempts to determine the file type
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
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'.
Returns the last error string.
