Welcome to Cappuccino!

Introduction

Cappuccino is an open source framework that makes it easy to build desktop-caliber applications that run in a web browser.

With Cappuccino, you don't concern yourself with HTML, CSS, or the DOM. You write applications with the APIs from Apple's Cocoa frameworks and the Objective-J language.

System Requirements

To run Cappuccino applications, all you need is a HTML5 compliant web browser.

You can develop Cappuccino applications with only a simple text editor on any platform.

If you are on a Mac, our integration with Xcode leverages the world-class visual development tools from Apple to create complex applications with minimal coding.

Node.js version alpha

There is currently an ongoing effort to switch JavaScript platform from Narwhal to Node.js. To try the Node.js version, do the following:

1. Install Node.js and npm from the Node.js website.

2. Run npm set prefix ~/.npm. This will set the default install location for npm to ~/.npm. The reasoning behind this is outlined in the section about permission issues below.

3. Add this line to your .zshrc or equivalent config file.

   export PATH="~/.npm/bin:$PATH"

4. Restart your shell.

5. Run npm install -g @objj/cappuccino.

6. Done! See below for basic usage.

Permisson issues

By default npm uses /usr/local/lib/node_modules as the install location for globally installed packages. This causes problems since users typically lack write permissions there. It is therefore recommended to either use a version manager, or change npm's default install location manually (which is what we did above). For more details on how to do this, see this article.

Basic usage

If the install succeeded you will be able to do the following to create a simple Cappuccino application:

1. capp gen HelloWorld
2. cd HelloWorld
3. python3 -m http.server
4. Go to localhost:8000 in your web browser.

Building Cappuccino from source

If you want to build Cappuccino from source you should clone the GitHub repository at https://github.com/cappuccino/cappuccino/ and checkout the node branch. Then you can use the command jake install to install Cappuccino and its tools locally.

To build from source, do:

1. git clone https://github.com/cappuccino/cappuccino.git

2. cd cappuccino

3. git checkout node

4. npm install

5. Make any desired changes to the codebase.

6. Make sure the environment variable CAPP_BUILD is set. This is done by adding the line

   export CAPP_BUILD="/path/to/cappuccino/build/directory"

   to your .zshrc or equivalent config file and of course changing the path to where you want to build Cappuccino.

7. Run jake install to build and install Cappuccino.

Beware that building and installing Cappuccino from source will overwrite the binaries installed from npm. To undo this, simply run npm install -g @objj/cappuccino again.

Getting Started

To write you first application, download the starter package.
