Dynasty Logo

Dynasty is a dynamically-typed, lazily evaluated, purely functional programming language that compiles to JavaScript.

Examples

You can find some Dynasty programs in the examples folder.

The most interesting ones are the Brainfuck interpreter and the Calculator web app.

The standard library and runtime code can be found in the core folder.

Building & running the compiler

Prerequisites

  • GHC (>= 9.6)
  • cabal (>= 3.8)

(Both can be installed via ghcup)

To compile Dynasty programs, use the following command:

cabal run . -- <target-dir>

The first invocation may take a while, since it will also build the compiler's dependencies.

By default, the compiler outputs a file named main.js. You can include it in a <script> tag inside an HTML document to load it in the browser, or run it directly using a JS runtime like Node.js, Deno, or Bun.

VS Code Extension

To install the VS Code extension, run ./dynasty-vscode/install.sh.
