Tiny Export

Export tool for Tiny - Arduboy sprite and scene editor.

Install

mkdir thing
cd thing
npm init -f
npm intall tiny-export

Usage

Create config for your export:

// config.js
const path = require('path');
 
const root = __dirname;
 
module.exports =  {
  target: path.join(root, 'src'),
  cache:  {
    payload: path.join(root, 'payload-cache.json'),
    readable: path.join(root, 'payload-readable.json')
  },
  url: 'https://...your-app-id.cloudfunctions.net/export-project',
  token: 'token for project you want to export'
};

Create fetch.js which will fetch and cache locally your current project (sprites, scenes):

// fetch.js
let config = require('./config');
let { run } = require('tiny-export');
 
run(config, async runtime => {
 
  await runtime.fetch();
 
});

Run fetch:

node ./fetch.js

Create generate.js which will take cached json and generate C++ code:

// generate.js
let config = require('./config');
let { run } = require('tiny-export');
let path = require('path');
 
let local = filename => path.join(__dirname, filename);
 
run(config, async runtime => {
 
  let payload = await runtime.project();
 
  let pair = async (filename, props) => {
    let file = ext => runtime.render(local(`templates/${filename}.${ext}.ejs`), props);
    await Promise.all([
      runtime.write(`${filename}.cpp`, file('cpp')),
      runtime.write(`${filename}.h`, file('h'))
    ]);
  }
 
  await pair('tiny', payload);
 
});

For this example I'm generating tiny.cpp and tiny.h using tiny.cpp.ejs and tiny.h.ejs (which are identical for this example):

<%# templates/tiny.cpp.ejs %>
<%# templates/tiny.h.ejs %>
namespace Tiny {
  // Project: <%= title %> 
 
  // Sprites 
<% project.sprites.forEach(sprite => { %>
  // <%= sprite.index %>: <%= sprite.identifier %> <%= sprite.size.width %> <%= sprite.size.height %> 
<% }) %>
}

Run generate:

node ./generate.js
