A WebAssembly import dependency linker

Waldo

A WebAssembly import dependency linker.

Goals

• Simplify the process of managing imports.
• Be toolchain-agnostic.
• Create a clean, simple, glue code that – itself – is engine-agnostic.
• Reduce code duplication in instances where you need multiple WebAssembly modules
• Define import libraries in JavaScript.
• Export typings for your module's glue code and exports.

Usage

waldo [OPTIONS] --output <OUTPUT> <PATH>

Arguments:
  <PATH>  The path to the WebAssembly file to find imports for

Options:
  -L, --lib <LIBRARIES>       Add a library to look for imports in
  -D, --define <DEFINITIONS>  Define a variable for the libraries to use (used by `import.meta.definitions.name`)
  -o, --output <OUTPUT>       The path to write the generated glue code to
  -h, --help                  Print help
  -V, --version               Print version

Defining a library

@linkage({ namespace: "env" })
function sum(a, b) {
	return a + b;
}
