holyc

Installation

npm install -g holyc

The first installation will be slow.

holyc++ path/to/something.cpp

The WASM binary will then be available at something.cpp.wasm.

name	description
`--show-wast`	Show wast output
`--no-clean`	Disable cleaning of intermediate formats

Emscripten is able to compile the libc where Holyc won't.

You can easily reproduce this benchmark by following C_to_wasm.

hello.c:

int main() {
  return 0;
}

Emscripten:

file	size (bytes)
hello.wasm	21856
hello.js (loader)	99710

Holyc:

file	size (bytes)
hello.wasm	78
hello.js (loader)	unknown currently (see here for a hint)
