Building MRuby for WASM
The Dockerfile builds everything needed. It puts the two required files at /build/ruby.js, /build/ruby.wasm. In order to extract these two files from the build, you can start a container with a bind-mount and copy them out. For example:
docker build -f ./lib/interfacets/mruby/build.dockerfile -t mruby .
docker run -v./build:/build2 mruby cp /build/ruby.js /build/ruby.wasm /build2
