Hot Reload Support

[couturecraigj]

I would really like to see one of these new WASM compilers include Hot Reload Support. I tried this and it crashes. Is there anything that I can do to make this work with hot reload? I have some ideas for simpler programs...

A trivial approach would be to simply strip the rusty types then transform it into more javascripty language...

  string
    .replace(/extern.*;/gm, '')
    .replace(/use.*;/gm, '')
    .replace(/#\[.*\]/gm, '')
    .replace(/eprintln!/gm, 'console.log')
    .replace(/extern (.|\n)[^}]*\}/gm, '')
    .replace(/pub fn (\w*)/gm, 'module.exports.$1 = function $1')
    .replace(/{.[^}]*}/gm, '%s')
    .replace(/\) -> \w* {/gm, '){')
    .replace(/: (i32|f32)/gm, '')
    .replace(/eprintln!/gm, 'console.log')
    .replace(/^(\s[^\n]*)\n}/gm, 'return $1; }')
    .replace(/(\s|\n)(\s*)/gm, ' ');

Do you know if this is possible?!?!?

I just wish we could sorta run things exactly the same in development as production without having to worry about comment things out in development.
