NAME

typemap - A tool for manipulating typemaps

VERSION

version 0.001

SYNOPSIS

 typemap --merge +Magic

DESCRIPTION

This script can modify, create and write Perl XS typemap files. If you don't know what a typemap is, please confer the perlxstut and perlxs manuals.

ARGUMENTS

• file <filename>

  The file that we're manipulating, this defaults to typemap.

• merge <module-name>

  This option takes an ExtUtils::Typemaps module name as argument, and will merge that into the current typemap. The prefix + is replaced with ExtUtils::Typemaps:: for convenience. This may be passed multiple times.

• no-replace

  This will disable replacing existing entries.

• add-string <content>

  This will parse a string entry and merge it into the typemap.

• add-file <filename>

  This will parse a file and merge it into the typemap.

• add-type <c-type> <xs-type>

  This will add a type mapping entry to the typemap. It takes two arguments: a C type (e.g. double) and an XS type (e.g. T_NV).

• add-input <xs-type> <code>

  This will add an input entry to the typemap. It takes two arguments: an XS type (e.g. T_NV) and a piece of code to associate with it (e.g. '$var = ($type)SvNV($arg);').

• add-output <xs-type> <code>

  This will add an output entry to the typemap. It takes two arguments: an XS type (e.g. T_NV) and a piece of code to associate with it (e.g. 'sv_setnv($arg, (NV)$var);').

• remove-type <c-type>

  This takes a C type as its only argument, and will remove the type mapping for that type.

• remove-input <xs-type>

  This takes an XS type as its only argument and will remove the associated input entry.

• remove-output <xs-type>

  This takes an XS type as its only argument and will remove the associated output entry.
