ScrapboxでRubyを動かす

ruby-head-wasm-wasiを使ってScrapboxでRubyを動かしてみる

お試し

以下のコードを開発コンソールに貼り付けてる

code:js

await (async () => {

const { run } = await import("/api/code/villagepump/ScrapboxでRubyを動かす/script.js");

const result = await run(

`9.times do |x|

9.times do |y|

end

puts

end`

);

alert(result);

})();

動かないもの

code:script.js

import { DefaultRubyVM } from "../../takker-dist/ruby-head-wasm-wasi-min/mod.js";

// Fetch and instntiate WebAssembly binary

const response = await fetch(wasmURL);

const buffer = await response.arrayBuffer();

const module = await WebAssembly.compile(buffer);

export const run = async (code) => {

// この辺 Rudy on Browserの真似

const outputBuffer = [];

const stdout = (line) => outputBuffer.push(line);

const { vm } = await DefaultRubyVM(module, {

consolePrint: true,

consoleHandler: { 1: stdout, 2: stdout },

});

vm.printVersion();

try {

const result = vm.eval(code);

if (outputBuffer.length === 0) return result.toString();

return outputBuffer.join("");

} catch(e) {

if (e instanceof Error) throw e;

return e;

}

};
