The Common WebAssembly API is a minimal specification of the standard API for non-Web WebAssembly usermode environments.

A few new types (which all lower to primitive WASM types) are introduced in types.md.

The CWA API is organized as namespaces, which each corresponds to a specific set of API functions.

CWA API functions should be accessible via the external module named cwa.

Every namespace should contain only lower-case ASCII characters in its name, and have its definitions in ns/{namespace}.md.

Every function should contain only lower-case ASCII characters, digits(0-9), and _ in its name, and the first character cannot be a digit.

Functions from namespaces are visible to WebAssembly modules with the name {namespace}_{function}.

If you are not sure, open an issue to discuss your idea first.

After you've finished writing the definitions & explanations of your new namespaces/functions, open a pull request and we would be happy to review :-)
