Alien::wasmtime

Find or download wasmtime for use by other Perl modules

SYNOPSIS

use Alien::wasmtime;
use FFI::Platypus 1.00;

my $ffi = FFI::Platypus->new(
  api => 1,
  lib => [Alien::wasmtime->dynamic_libs],
);

DESCRIPTION

NOTE: If you want to call WebAssembly from Perl you want to use Wasm or Wasm::Wasmtime instead.

This Alien provides wasmtime a library runtime for Wasm (WebAssembly). It's intended to be used by FFI (not XS) to build Wasm bindings for Perl.

METHODS

dynamic_libs

my @libs = Alien::wasmtime->dynamic_libs;

Returns the list of libraries needed to use wasmtime via FFI.

ENVIRONMENT

• ALIEN_WASMTIME_VERSION

  Override the version of wasmtime downloaded. To get the latest development release you can install with:

  $ env ALIEN_WASMTIME_VERSION=dev cpanm Alien::wasmtime

CAVEATS

Wasm and wasmtime is a moving target at the moment, so expect breakage until it becomes stable.

Normally Aliens should try to use the system library before downloading from the internet. Since wasmtime isn't provided by many package managers yet, we skip this step for now. In the future we will support probing of the system wasmtime.

This Alien is geared for use with FFI only.

SEE ALSO

• Wasm

  High level interface to WebAssembly which uses wasmtime under the covers.

• Wasm::Wasmtime

  Lower-level direct interface to Wasmtime itself from Perl.

• FFI::Platypus

  Foreign function interface to dynamic libraries in perl via libffi.
