AoE2 Random Map Scripting for humans

JavaScript parser and linter for Random Map Scripts (RMS) for the Age of Empires II video game.

• Online playground (repo)
• VS Code extension (repo)
• Sublime Text package (repo)

Mangudai is published as an NPM package compatible with Node.js and browsers.

npm install mangudai

Use a tool like Webpack or Rollup to include Mangudai in your front-end app.

The code is compiled to ES5 (old and stable JavaScript) before publishing, so the module has maximum compatibility out-of-the-box.

Let's parse an RMS script into an Abstract Syntax Tree (AST) and lint it.

import { parse, lint } from 'mangudai'

const { ast, errors } = parse('<PLAYER_SETUP> \n random_placement')

if (errors.length) {
  console.log('Unable to parse the script! Probably invalid syntax.', errors)
} else {
  const lintErrors = lint(ast)
  console.log(`Linter found ${lintErrors.length} problems.`, lintErrors)
}

Mangudai is written in TypeScript and exports all relevant typings.

• parse( script: string ) => { ast: Script, errors: ParseError[] }

• lint( ast: Script ) => LintError[]

This project is still in its early development stage. Any help is greatly appreciated! Feel free to ask questions in issues. PRs accepted.
