If you are a developer and want to help build CodaLab, this page will explain how to to get started.
To use and test the submission process, a queue server will need to be installed. RabbitMQ installs easily on Linux and Windows and requires no configuration out of the box for testing purposes. A database besides SQLite is recommended. MySQL and Postgres work on Windows, Linux and Mac.
CodaLab is built with Python, supporting development on local machines with Windows, Linux, Mac and BSD. If something is broken, please open a new issue.
In this section, we will walk you through installing Python 2.7.x, installing prerequisites, and running the CodaLab site in a local virtual environment.
Assuming a fresh Ubuntu install the following commands should get you started. Environment variables are used to control settings for a flexible build process. The build script will accept an environment variable, CONFIG_MODULE_PATH, to a location of an installable python source package which will get installed and be used as the settings module, which is specifically specified with DJANGO_SETTINGS_MODULE.
Install Python 2.7. For current Debian-based Linux distributions (such as Ubuntu), BSD and Mac Python 2.7 is usually installed. However Redhat-based Linux distributions, such as RHEL and CentOS, are sometimes behind the curve and do not have Python 2.7. As of this writing, CentOS 6.4 is at Python 2.6, which is well on its way to EOL. Python 2.6 may work, but code will be written with 2.7 and 3.3+ in mind. Below are instructions for Ubuntu Linux 13.04+.
sudo apt-get install python-pip
sudo pip install --upgrade pip
pip install virtualenv
sudo apt-get install git
Install the prerequisites for MySQL-Python.
sudo apt-get install build-essential python-dev libmysqlclient-dev
Install Compass (optional)
If you want to make changes to CodaLab's stylesheets via SCSS files, you will need to install Compass. Note that this step is only required if you plan to make any changes to stylesheets.
Install Ruby from http://rubyinstaller.org/downloads/. (Version 1.9.3 is recommended). During installation be sure to select the option to add Ruby to your PATH.
Open a command window and install compass by executing:
sudo gem install compass
Take the following steps to generate the css files after you've made changes to the scss files in the sass folder:
Alternatively, you can run the
compass watchcommand to start a process which will automatically re-generate the files when changes are made:
compass watch .
Install Java from https://www.java.com/en/download/.
Add Java bin folder to the PATH environment variable.
Download and extract Closure from http://dl.google.com/closure-compiler/compiler-latest.zip.
