NAME

ExtUtils::Typemaps::Cmd - Quick commands for handling typemaps

SYNOPSIS

From XS:

INCLUDE_COMMAND: $^X -MExtUtils::Typemaps::Cmd \
                 -e "print embeddable_typemap(q{Excommunicated})"

Loads ExtUtils::Typemaps::Excommunicated, instantiates an object, and dumps it as an embeddable typemap for use directly in your XS file.

DESCRIPTION

This is a helper module for ExtUtils::Typemaps for quick one-liners, specifically for inclusion of shared typemaps that live on CPAN into an XS file (see SYNOPSIS).

For this reason, the following functions are exported by default:

EXPORTED FUNCTIONS

embeddable_typemap

Given a list of identifiers, embeddable_typemap tries to load typemaps from a file of the given name(s), or from a module that is an ExtUtils::Typemaps subclass.

Returns a string representation of the merged typemaps that can be included verbatim into XS. Example:

print embeddable_typemap(
  "Excommunicated", "ExtUtils::Typemaps::Basic", "./typemap"
);

This will try to load a module ExtUtils::Typemaps::Excommunicated and use it as an ExtUtils::Typemaps subclass. If that fails, it'll try loading Excommunicated as a module, if that fails, it'll try to read a file called Excommunicated. It'll work similarly for the second argument, but the third will be loaded as a file first.

After loading all typemap files or modules, it will merge them in the specified order and dump the result as an embeddable typemap.
