# Darabonba Code Generator for C++

## Installation

Darabonba Code Generator was designed to work in Node.js. The preferred way to install the Generator is to use the [NPM](https://www.npmjs.com/) package manager. Simply type the following into a terminal window:

```shell
npm install @darabonba/cpp-generator
```

## Usage

Generate C++ Code

```javascript
'use strict';

const path = require('path');
const fs = require('fs');

const parser = require('@darabonba/parser');
const CppGenerator = require('@darabonba/cpp-generator');

const sourceDir = "<Darabonda package directory>";
const outputDir = "<Generate output directory>";

// generate AST data by Darabonba Parser
let packageMetaFilePath = path.join(sourceDir, 'Darafile');
let packageMeta = JSON.parse(fs.readFileSync(packageMetaFilePath, 'utf8'));
let mainFile = path.join(sourceDir, packageMeta.main);
let ast = parser.parse(fs.readFileSync(mainFile, 'utf8'), mainFile);

// initialize generator
let generatorConfig = {
    ...packageMeta,
    pkgDir: sourceDir,
    outputDir
};

let generator = new CppGenerator(generatorConfig);

// generate cpp code by generator
generator.visit(ast);

// The execution result will be output in the 'outputDir'
```
