lolcode.macro v1.3.1
LOLCODE-to-JavaScript compiler babel macro
A fully functioning LOLCODE-to-JavaScript compiler implemented as a Babel macro. You never thought you wanted this and now here it is. Youβre welcome. π±
Let me start by proving that this crazy contraption works π
https://codesandbox.io/s/github/Swizec/lolcode.macro-example
Here you have a CodeSandbox with the legendary FizzBuzz implemented in LOLCODE. A Babel macro compiles it to a JavaScript function at build-time and you use it as any ole JavaScript at runtime.
LOLCODE goes in π±
HAI
I HAS A count ITS 1
IM IN YR fizzbuzz UPPIN YR count TIL BOTH SAEM count AN 30
I HAS A div ITS MOD OF count AN 3
IT R BOTH SAEM 0 AN div
O RLY?
YA RLY
VISIBLE "Fizz"
MEBBE BOTH SAEM 0 AN MOD OF count AN 5
VISIBLE "Buzz"
NO WAI
VISIBLE count
OIC
IM OUTTA YR fizzbuzz
KTHXBYE
JavaScript comes out βοΈ
var fizzbuzz = function (stdlib) {
return function () {
var IT;
var count = 1;
for (; !stdlib["BOTH SAEM"](count, 30); count++) {
var _IT = void 0;
var div = stdlib["MOD OF"](count, 3);
_IT = stdlib["BOTH SAEM"](0, div);
if (_IT) {
var _IT2 = void 0;
console.log("Fizz");
} else if (stdlib["BOTH SAEM"](0, stdlib["MOD OF"](count, 5))) {
var _IT3 = void 0;
console.log("Buzz");
} else {
var _IT4 = void 0;
console.log(count);
}
;
}
;
};
}(lolcode_macro_dist_lolstdlib__WEBPACK_IMPORTED_MODULE_2__["default"]);
Taken from Chrome DevTools source maps. That's after Webpack and Babel do their thing. Intermediate output from lolcode.macro
is modern JavaScript with lets and consts.
How to use
Install from NPM
$ npm install lolcode.macro
Then import and use similarly to CSS-in-JS or GraphQL
import { lolcode } from "lolcode.macro";
import lolstdlib from "lolcode.macro/dist/lolstdlib";
const fizzbuzz = lolcode`
