Encode::Alias(3pm)					 Perl Programmers Reference Guide					Encode::Alias(3pm)

NAME

       Encode::Alias - alias definitions to encodings

SYNOPSIS

	 use Encode;
	 use Encode::Alias;
	 define_alias( newName => ENCODING);

DESCRIPTION

       Allows newName to be used as an alias for ENCODING. ENCODING may be either the name of an encoding or an encoding object (as described in
       Encode).

       Currently newName can be specified in the following ways:

       As a simple string.
       As a qr// compiled regular expression, e.g.:
	     define_alias( qr/^iso8859-(d+)$/i => '"iso-8859-$1"' );

	   In this case, if ENCODING is not a reference, it is "eval"-ed in order to allow $1 etc. to be substituted.  The example is one way to
	   alias names as used in X11 fonts to the MIME names for the iso-8859-* family.  Note the double quotes inside the single quotes.

	   If you are using a regex here, you have to use the quotes as shown or it won't work.  Also note that regex handling is tricky even for
	   the experienced.  Use it with caution.

       As a code reference, e.g.:
	     define_alias( sub { return /^iso8859-(d+)$/i ? "iso-8859-$1" : undef } , '');

	   In this case, $_ will be set to the name that is being looked up and ENCODING is passed to the sub as its first argument.  The example
	   is another way to alias names as used in X11 fonts to the MIME names for the iso-8859-* family.

       Alias overloading

       You can override predefined aliases by simply applying define_alias().  The new alias is always evaluated first, and when neccessary,
       define_alias() flushes the internal cache to make the new definition available.

	 # redirect SHIFT_JIS to MS/IBM Code Page 932, which is a
	 # superset of SHIFT_JIS

	 define_alias( qr/shift.*jis$/i  => '"cp932"' );
	 define_alias( qr/sjis$/i	 => '"cp932"' );

       If you want to zap all predefined aliases, you can use

	 Encode::Alias->undef_aliases;

       to do so.  And

	 Encode::Alias->init_aliases;

       gets the factory settings back.
