`nwc`, a NanoWasm compiler

nwc is a command-line tool that takes a MVP WebAssembly file and appends NanoWasm custom sections to it, so that NanoWasm-capable interpreters such as nanowasm can consume them.

Building from source

nwc only requires a C99 environment to build. The build system is based on CMake and can be configured using the conventional process in CMake projects:

cmake -B build

Then, build with:

cmake --build build/

Usage

The command below shall generate a NanoWasm-compatible file given by out from a MVP WebAssembly file given by infile:

nwc <infile> <outfile>

Take into account that infile must not contain any NanoWasm custom sections.
