Compiler

Portable compiler sources that compile to both JavaScript using tsc and WebAssembly using asc.

Architecture

Usage

import assemblyscript from "assemblyscript";
...

Building

Building to JavaScript

To build the compiler, run:

npm run build

The rebuild automatically when there are changes, do:

npm run watch

Building to WebAssembly

To build the compiler to a WebAssembly binary, run:

npm run bootstrap

Uses the AssemblyScript compiler compiled to JavaScript to compile itself to WebAssembly, building to WebAssembly again using itself compiled to WebAssembly. Builds to build/. Performs a git diff to make sure that both the initial and the final artifacts are the same. Note that this builds the compiler as a library, while the asc frontend setting it up and feeding it source files is JavaScript for now.

Running asc with the WebAssembly variant:

asc [options...] --wasm build/assemblyscript.release-bootstrap.js

Running the compiler tests with the WebAssembly variant:

npm run test:compiler -- --wasm build/assemblyscript.release-bootstrap.js
