v0.4.0

What's Changed

Breaking Changes

• #315

HTTP calls will be disallowed by default now. If you want to enable HTTP you need to specify the hosts that the plug-in is allowed to communicate with. If you want to allow all hosts you can set it to {allowed_hosts: ["*"]} in the manifest. However, this isn't recommended unless you have some trust in the plug-in or are controlling the networking by some other means.

• #335

In this PR we are creating an implicit context so people don't need to know about it if they don't care. In some languages function signatures have changed to make context an optional argument when creating a plug-in.

Full Changelog: v0.0.1...v0.1.0

RELEASE v0.1.0

Extism is the universal plug-in system. Run WebAssembly extensions inside your app. Use idiomatic Host SDKs for Go, Ruby, Python, Node, Rust, C, C++, OCaml, Haskell, PHP & more (others coming soon).

Things may be incomplete or undocumented or difficult to install, but not for long!

This is a preview to share progress on a usable version while we wrap up some docs, automation, package distribution, installation process, etc.

Preview Installation & Usage

Try the extism CLI:

• Install from https://github.com/extism/cli, read usage in the README.md
• Some Host SDKs are available via respective package managers / distribution systems. Try those!

Or:

• Clone the repository.
• Copy the language SDK you want to use (./node, ./ruby, ./python etc are language SDKs in the root of the repo).
• Download a pre-built release for your system (attached below), or build the project from source (see the Makefile in the root, make build).
• Install libextism.{so|dylib} and extism.h into your library and include paths respectively. (sudo make install does this)

Expect the entire process above to be simplified away soon...
