Technology

The following technologies are used for Malt.io:

• Git
• Google App Engine
• Python
• Webapp2
• Jinja2
• HTML5
• CoffeeScript
• Less
• Gravatar
• Stripe
• Nose and Jasmine

Getting Started

You can run a local copy of the site for development. Several prerequisites must be installed and configured first. I highly suggest checking out the Sublime Text 2 editor, grabbing the Sublime Package Control add-on and installing the CoffeeScript, LESS, and PEP8 packages.

On Ubuntu Linux:

sudo apt-get install git python-pip nodejs npm

# Get Google AppEngine
wget http://googleappengine.googlecode.com/files/google_appengine_1.7.1.zip
unzip google_appengine_1.7.1.zip

# Get other dependencies
pip install pycco nose NoseGAE nose-exclude
npm install --global coffee-script less uglify-js jasmine-node

# Get Malt.io codebase
git clone https://github.com/danielgtaylor/malt.io.git

# Run the development server
cd malt.io
./genStatic.sh
../google_appengine/dev_appserver.py .

You should now be able to access the site at http://localhost:8080/

On Windows:

• Install GitHub

  • Set the shell in tools -> options -> default shell to Git Bash

• Install Python 2.7.x

• Install Python easy_install

• Install Node.js

• Install Google AppEngine

• Modify your PATH

  1. Right-click on Computer in the Start Menu, select Properties
  2. Click Advanced system settings
  3. Click Environment variables
  4. Select PATH and click Edit in the top half of the window
  5. Ensure your path contains python, python scripts, app engine and npm: ...;C:\Program Files\Google\google_appengine;C:\Python27;C:\Python27\Scripts;C:\Users\username\AppData\Roaming\npm\

• Click Clone in Windows above to clone Malt.io

• Then run Git Shell from your start menu and do:

  # Install other dependencies
  easy_install pycco nose NoseGAE nose-exclude
  npm install --global coffee-script less uglify-js jasmine-node
  
  # Run the development server
  cd malt.io
  ./genStatic.sh
  dev_appserver.py .

You should now be able to access the site at http://localhost:8080/

Static Files

Malt.io uses CoffeeScript and Less, which are languages built on top of Javascript and CSS, respectively. You should never modify the Javascript or CSS files manually.

In order to see changes to these files in the browser you must first regenerate their compiled Javascript and CSS. A script is provided for this:

cd malt.io
./genStatic.sh

This script generates a main CSS file, a main Javascript file, and updates query strings so that browser caching isn't an issue. You must run this script to see your changes.

To see changes to the Python code or Jinja2 templates, just ensure the development server is running and reload the page in your browser. The development server handles reloading updated files automatically.

Documentation

You can generate code documentation for both the server-side Python and client-side CoffeeScript:

cd malt.io
./genDocs.sh

You will see a bunch of new HTML files in the docs directory. There is one documentation file per file of source code.

Unit Testing

Unit tests are built into the project in the form of doctests and UnitTest subclasses for Python, and Jasmine tests for CoffeeScript. You can run the entire test suite with the following:

cd malt.io
./runTests.sh

This will test all the server-side Python excluding the contrib folder, and all the client-side CoffeeScript.

Unit tests should be run before doing a commit. This helps to ensure that nothing breaks on the live site. Unit tests will be run before any pull request is accepted, so please make sure your changes do not break existing code!

Code Overview

The following describes the general layout of the code within this project:

• contrib: third party packages
  • paodate: date handling
  • stripe: payment processing
  • unidecode: unicode transliteration
• handlers: http request handlers that render pages
• models: datastore model definitions and methods
• static: non-dynamic files served by the web server
  • img: images
  • scripts: client-side coffeescripts and javascripts
  • styles: less and css stylesheets
• templates: html template files using jinja2
• app.yaml: google appengine app definition
• main.py: main script entrypoint
• settings.py: site settings
• urls.py: maps regular expressions to handlers
• util.py: various utility methods
