What is Mustgen?

Mustgen is a very simple file generator based on handlebars. It takes {{mustached}} template and javascript object as a map with values and file definitions, then generates string using handlebars, and writes it to a file.

Why it exists?

It was created as an alternative code generator for Entitas.

Quick start

0. Have Node.js installed

If you don't have node.js installed on your machine, install from Node.js website.

1. Go to your project path

$ cd pathToYourProject

1. Install Mustgen

2. Add template hello.hbs at root of your project

Hello {{name}}.
Random words: {{#words}}{{.}} {{/words}}
And this is block of {{name}} {{lastname}}.

3. Add map.js at root of your project

var helloFile = {

            lastname: "King"
module.exports = {
    files: [helloFile],
    helpers: {},
    partials: {},
    // For safety reasons, output folder name  
    // should contain '_generated'.
