TouchDevelop

TouchDevelop is a touch-friendly app creation environment for iPad, iPhone, Android, Windows, Mac, Linux developed with <3 at Microsoft Research. Our mobile-friendly editor makes coding fun, even on your phone or tablet!

This repo contains the source code of the TouchDevelop editor. If you are intending to write TouchDevelop scripts, you probably want to go to touchdevelop.com:

• stable: https://www.touchdevelop.com/app
• beta: https://www.touchdevelop.com/app/beta

• blog: https://www.touchdevelop.com/blog
• Hour Of Code tutorials: https://www.touchdevelop.com/hoc

What's in this repo?

The repo is mostly written in Typescript with tiny pieces of HTML gluing.

This repo contains the source code for:

• the browser client
• the compiler
• the editor
• the runtime
• the node.js client

However, you will not find the cloud backend code here. Indeed, https://www.touchdevelop.com takes care of storing and managing the scripts.

Contributing

There are many ways to contribute to TouchDevelop.

• submit bugs and help us verify fixes as they are checked in.
• review the source code changes
• contribute bug fixes or features.

If you're not a developer but still would like to help, we've got more tasks for you!

• help translate the user inferface: do you use TouchDevelop and speak a foreign language? You can help!

Building

In order to build TouchDevelop, ensure that you have Git and Node.js installed.

Clone a copy of the repo:

git clone https://github.com/Microsoft/TouchDevelop.git

Change to the TouchDevelop directory:

cd TouchDevelop

Install dependencies:

npm install jake -g
npm install tsd@next -g
tsd reinstall
npm install

Build:

export TD_SOURCE_MAPS=1 # optional, will slow down your build
jake

Running

After building, you can run TouchDevelop from a local node server by running:

jake local

The local instance can be accessed at http://localhost:4242/editor/local/.

Tests

jake test

Cleaning

jake clean

Documentation

All the docs are available online at https://www.touchdevelop.com/docs.

The docs are authored as TouchDevelop scripts in TouchDevelop itself. You can fork them and send pull requests from TouchDevelop itself to update them. You can update the local cache of documents by running this command:

jake update-docs

More handy commands

Our catch-all tool is build/client.js, which is compiled from tools/client.ts. Some of the common invocations of client.js are exposed as Jake targets.

# assumes TD_UPLOAD_KEY and TD_UPLOAD_USER are set, uploads a new test build
jake upload
# update the files in generated/
jake update-docs

Find out about other commands directly:

node build/client.js

The client.js is built by default.

The various repositories in the tree

• ast: contains the lexer, parser, type-checker and ast definitions for the TouchDevelop language
• browser: feature-detection
• editor: the TouchDevelop user interface that drives the website: hub, script list, editor itself
• generated: files needed for the build that are re-generated manually once in a while
• intellitrain:
• json:
• lib: the libraries exposed to TouchDevelop scripts, written in TypeScript
• libcordova: Apache Cordova specific implementations
• libnode: Node.JS specific implementations
• libwab: WebAppBooster implementations, used by the Windows Phone client
• libwinRT: (deprecated) WinRT specific implementations
• mc: Minecraft bindings
• noderunner: runs in the cloud, and parses TouchDevelop scripts / compiles them by responding to requests on /api.
• node-webkit: configuration files for the node-webkit app creation
• officemix: office mix app host
• rt: various run-time support libraries for the TouchDevelop application: in-browser storage, cloud connection, promises, DOM utilities...
• runner: the run-time system for generated TouchDevelop apps; that is, once a TouchDevelop script is packaged as an app (webapp, cordova app, etc.), runner.js is the runtime system and the stub is in webapp
• shell: shell app used by Azure and node-webkit; basically a way to serve files locally
• storage: code for syncing your locally-stored scripts and the cloud storage, in the TouchDevelop application
• tools: internal tools that are part of the build (pre-processing)
• webapp: the stub file that is used to generate the HTML5 Web App when exporting a script
• www: the base files that make up the TouchDevelop website (html and css)

Structure of the generated website / app

When packaged, as the website or as an app, the directory structure is flat. That is, the CSS and HTML files from www/ as well as the generated .js files from build/ all end up in the same directory. That way, index.html can refer to main.js without worrying.

When running locally (via jake local), the local node server knows where to find the right files to give the illusion that all files are in the /editor/local/ directory of the web server.
