Manual Reference Pages - FILE::TYPE (3)
File::Type - determine file type using magic
my $ft = File::Type->new();
# read in data from file to $data, then
my $type_from_data = $ft->checktype_contents($data);
# alternatively, check file from disk
my $type_from_file = $ft->checktype_filename($file);
# convenient method for checking either a file or data
my $type_1 = $ft->mime_type($file);
my $type_2 = $ft->mime_type($data);
File::Type uses magic numbers (typically at the start of a file) to
determine the MIME type of that file.
File::Type can use either a filename, or file contents, to determine the
type of a file.
Returns a new File::Type object.
Takes either data or a filename, determines what it is, and passes the
argument through to the relevant method below. If the argument is a
directory, returns undef.
Opens $filename (if possible; if not, returns undef) and returns the MIME
type of the file.
Matches $data against the magic database criteria and returns the MIME
type of the file.
* Add additional magic match criteria
Some magic definitions in the mime-magic file used in the creation of this
module vary from those in other apps (eg image/x-png not image/png).
File::MMagic and File::MimeInfo perform the same job, but have a number
of problems that led to the creation of this module.
File::MMagic inlines a copy of the magic database, and uses a DATA
filehandle, which causes problems when running under mod_perl.
File::MimeInfo uses an external magic file, and relies on file extensions
rather than magic to determine the mime type.
As a result, File::Type uses a seperate module and script to create the
code at the core of this module, which means that there is no need to
include a magic database at all, and that it is safe to run under mod_perl.
File::Type::Builder, which generates the code at the heart of this module.
File::Type is built from a mime-magic file from cleancode.org. The original
can be found at <http://cleancode.org/cgi-bin/viewcvs.cgi/email/mime-magic.mime?rev=184.108.40.206>.
