Tooling

WARNING: severely out of date. The uw8 binary includes a lot of the tool features below.

The Web Assembly Binary Toolkit includes a few useful tools, eg. wat2wasm to compile the WebAssemby text format to binary wasm and wasm2wat to disassemble wasm binaries.

If you don't like the look of the .wat text format, you might want to take a look at CurlyWas, a curly-braces infix syntax for WebAssembly.

Once you have a size-efficient .wasm file, you can use uw8-tool (currently included in the MicroW8 repository) to strip off sections of the WebAssembly module that are provided by the MicroW8 platform.

Writing code for MicroW8 in C, Rust, AssemblyScript etc. should absolutely possible but no examples are provided, yet.
