Compile MiniSat to WebAssembly using emscripten.
Note: This is a fork of https://github.com/jgalenson/research.js where we only care about the minisat directory.
MiniSat (http://minisat.se) will be cloned from the original repository (https://github.com/niklasso/minisat) and patched in order to be compatible with emscripten. Most notably minisat-wasm will parse the DIMACS input from a string instead of a file.
- make
- emscripten
Follow the instructions on https://kripken.github.io/emscripten-site/docs/getting_started/downloads.html in order to install emscripten and all of its dependencies.
Invoke make to build minisat-wasm using emscripten.
Invoke make test to build and test minisat-wasm.
Invoke make clean to clean project.
Usage of minisat-wasm as a CommonJS module is demonstrated in test.js:
const Module = require("./minisat-wasm.js");
let solve = null;
Module.onRuntimeInitialized = () => {
try {
solve = Module.cwrap("solve", "string", ["string", "number"]);
if (solve) {
run();
}
}
catch (error) {
console.error(error.message);
}
};
function run() {
assert("p cnf 3 2\n1 -3 0\n2 3 -1 0", "SATISFIABLE");
assert("p cnf 1 2\n1 0\n-1 0", "UNSATISFIABLE");
assert("Hello, world!", "");
}
function assert(dimacs, expected) {
let result = solve(dimacs, dimacs.length);
console.log(`Got: ${result}`);
console.log(`Expected: ${expected}`);
console.log(`Success: ${result === expected}`);
console.log("--------------------------------");
