memphis-js

memphis-js is the thin JavaScript wrapper for the Memphis WebAssembly build.

It unifies the three existing consumer patterns:

• Ozark: inspect (lex, parse, compile)
• Tupelo: run the Memphis REPL (createRepl)
• Shreve: run a script (run)

Initial API

import { getMemphis } from "@fromscratchcode/memphis-js";

const memphis = await getMemphis();

memphis.lex("x = 1");
memphis.parse("x = 1");
memphis.compile("x = 1");
memphis.run("print('hi')");

const repl = memphis.createRepl({ engine: "treewalk" });
repl.insertText("1 + 1");
const step = repl.submit();
repl.free();

Notes

• run() reflects the current Rust wasm export and uses the treewalk engine.
• createRepl() supports both "treewalk" and "bytecode_vm".
• getMemphis() initializes the wasm module once and returns a cached runtime facade.
