# [NAME](#NAME)

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

# [SYNOPSIS](#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](#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](#EXPORTED_FUNCTIONS)

## [embeddable\_typemap](#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.
