file::type::builder

File::Type::Builder(3)					User Contributed Perl Documentation				    File::Type::Builder(3)

NAME

       File::Type::Builder - parse mime-magic and generate code

SYNOPSIS

	   my $build = File::Type::Builder->new();

	   while (<magic>) {
	     chomp;
	     my $parsed = $build->parse_magic($_);

	     my $code	= $build->string_start($parsed);
	     (or string_offset or beshort)
	   }

DESCRIPTION

       Reads in the mime-magic file format and translates it to code.  (This documentation would be longer if I really expected anyone other than
       me to run the code.)

METHODS

   new
       Creates a new File::Type::Builder object.

   parse_magic
       Pulls apart a line of a mime-magic file using a string of regular expressions.

       An example mime-magic file can be found in cleancode CVS at http://cleancode.org/cgi-bin/viewcvs.cgi/email/mime-magic.mime?rev=1.1.1.1
       <http://cleancode.org/cgi-bin/viewcvs.cgi/email/mime-magic.mime?rev=1.1.1.1>

   string
       Builds code to match magic that's of type string.

       Has to do some cleverness to make the regular expression work properly.

   be
       Builds code to match 'beshort' and 'belong' magic (eg audio/mpeg, image/jpeg).

PRIVATE METHODS

   _substr_matching
       Sometimes the data is smaller than the offset we're looking for in the file. If this is the case, then the file is obviously not of that
       type, and furthermore we should avoid issuing a couple of warnings that Perl would otherwise emit.

       This subroutine generates this code.

   _get_escapes
       Returns a reference to a hash defining characters that should not be escaped.

TODO

	   * Add handlers for other magic types (bedate, byte, etc)

	   * Make verbosity/logging nicer.

	   * Find more edge cases.

	   * Remove redundant 'if (length $data > 0)' check.

       Longer term:

	   * Fix for multiple magic format types?

BUGS

       Incomplete. Some known issues with odd entries in mime-magic. Skips some mime-magic lines.

SEE ALSO
