owi

owi is an OCaml toolchain to work with WebAssembly. It provides an interpreter as an executable and a library.

To get started, have a look at the quickstart section of the README.

API

• Owi.Parse Module providing functions to parse a wasm script from various kind of inputs.
• Owi.Types Types of text modules, as produced by the parser. Many parts of it are reused later in the interpreter.
• Owi.Compile Utility functions to compile a module until a given step.
• Owi.Check Initial check done on a module.
• Owi.Simplify Module to simplify a text module. It contains the types of simplified modules.
• Owi.Typecheck Module to typecheck a simplified module.
• Owi.Link Module to link a simplified/extern module and producing a runnable module along with a link state.
• Owi.Log Module to enable or disable the printing of debug logs.
• Owi.Interpret Module to interpret a linked module.
• Owi.Script Module to execute a full Wasm script.
• Owi.Pp Module to pretty print the various types such as text module or simplified module.
• Owi.Value Module to define externref values in OCaml. You should look in the `example` directory to understand how to use this before reading the code...
