File::LibMagic::FFI - Determine MIME types of data or files using libmagic
version 0.06
use File::LibMagic;
my $magic = File::LibMagic->new;
# prints a description like "ASCII text"
print $magic->describe_filename('path/to/file'), "\n";
print $magic->describe_contents('this is some data'), "\n";
# Prints a MIME type like "text/plain; charset=us-ascii"
print $magic->checktype_filename('path/to/file'), "\n";
print $magic->checktype_contents('this is some data'), "\n";
This module is a simple Perl interface to libmagic. It provides the same full undeprecated interface as File::LibMagic, but it uses FFI::Platypus instead of XS for its implementation, and thus can be installed without a compiler.
This module provides an object-oriented API with the following methods:
my $magic = File::LibMagic->new;
my $magic = File::LibMagic->new('/etc/magic');
Creates a new File::LibMagic::FFI object.
Using the object oriented interface provides an efficient way to repeatedly determine the magic of a file.
This method takes an optional argument containing a path to the magic file. If the file doesn't exist, this will throw an exception.
If you don't pass an argument, it will throw an exception if it can't find any magic files at all.
my $mime_type = $magic->checktype_contents($data);
Returns the MIME type of the data given as the first argument. The data can be passed as a plain scalar or as a reference to a scalar.
This is the same value as would be returned by the file command with the -i option.
my $mime_type = $magic->checktype_filename($filename);
Returns the MIME type of the given file.
This is the same value as would be returned by the file command with the -i option.
my $description = $magic->describe_contents($data);
Returns a description (as a string) of the data given as the first argument. The data can be passed as a plain scalar or as a reference to a scalar.
This is the same value as would be returned by the file command with no options.
my $description = $magic->describe_filename($filename);
Returns a description (as a string) of the given file.
This is the same value as would be returned by the file command with no options.
The FFI version does not support the deprecated APIs that File::LibMagic does.
