OCTAL's Source

This source is licensed under GPLv3, see LICENSE.txt (note: metacademy's content is CC BY SA 3.0).

OCTAL is based upon Metacademy: https://github.com/metacademy/metacademy-application With a live demo at http://www.metacademy.org

The following instructions bring up a development version of OCTAL. Look at the production directions for creating a production-level OCTAL server.

Installation

Preliminary requirements

• python 2.7X: NB: install python-devel if you're using a package manager such as apt-get. The following command should print a path (if this command raises an exception, make sure that you have the python-devel version installed):

        python -c 'from distutils.sysconfig import get_makefile_filename as m; print m()'
  

• gcc: Install gcc (OSX users: installing the OSX developer tools is probably the easiest way to do this). The following command should not throw an error:

    gcc -v
  

• pip Install pip; here are pip's installation instructions. The following command should not throw an error:

    pip -V
  

• node.js (needed to run tests): Install node The following command should not throw an error:

    node -v
  

• Make sure you have installed the following packages:

    freetype-devel gcc-gfortran (Linux)
    freetype gfortran (Mac OS X, via homebrew)
    easy_install virtualenv (both)
  

• On Mac OS X, setup freetype:

    ln -s /usr/local/opt/freetype/include/freetype2 /usr/local/include/freetype
  

Mac OSX and *nix

1. create a top-level octal directory in a desired location, e.g. mkdir -p ~/MyProjects/octal

2. go to the top-level octal directory cd ~/MyProjects/octal

3. from your top-level octal directory, clone the application repo:

    git clone https://github.com/danallan/octal-application.git
   

4. go to the octal-application directory

    cd octal-application
   

5. install the octal application (note: this project uses a virtual environment for development):

    make
   

   If you are on OS X and have a version of Xcode >= 5.1, you might need to prefix the above command with this:

    ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future make
   

Optional: create a superuser

    python app_server/manage.py createsuperuser

Scipy dependency

OCTAL currently depends scipy. Scipy can be tricky to install (pip install scipy won't work unless you have all of the systems-level dependencies), but Google might help here. Once that's done, link its site-packages folder to to your virtual environment's lib/python2.7/site-packages/ folder. One example (you might have to adapt to your install):

    ln -s /usr/local/lib/python2.7/site-packages/scipy lib/python2.7/site-packages/

Execution

Mac OSX and *nix

1. start the virtual environment (you must do this for each new session)

    source ../meta_venv/bin/activate
   

2. start the test servers

    ./run_test_servers.sh
   

3. Open localhost:8080 with a modern javascript-enabled browser

Note: the initial search may take some time to load (the backend must load the graph into memory), but all subsequent pages should load much quicker.
