OSCAd 2.0: Open Source Compliance Advisor

OSCAd is written in the Python programming language and uses the Pyramid Web Framework and Jinja2 Engine for templating. Translations are based on gettext message catalogs. Translations in the templates are done with the in the templates integrated i18n facilities. In normal Python code translationstring is used.

OSCAd is tested with

  • CPython 2.6
  • CPython 2.7
  • CPython 3.2
  • CPython 3.3
  • PyPy 2.1 (Python 2.7)

When the documentation mentions the python binary it always means the binary in your virtualenv. So be sure to activate the virtualenv or specify the absolut path to the binary. For more information about virtualenv take a look at http://www.virtualenv.org/

History

OSCAd is an interactive version of the Open Source License Compendium (OSLiC). It has been created to allow anyone to make sure they comply with the licenses of Open Source components they are using.

This software is the successor to the original OSCAd application written by Karsten Reincke from the Deutsche Telekom. You can find the original software on https://github.com/dtag-dbu/oscad. We thank Mr. Reincke and the Deutsche Telekom for allowing us to be part of a great community and for entrusting us with further development of OSCAd. The Deutsche Telekom will continue to maintain and develop the OSLiC document.

Installation

  • Make sure virtualenv and pip are installed
# apt-get install python-virtualenv python-pip
  • Create and activate a new virtualenv
$ cd $OSCAD_DIR
$ virtualenv venv
$ source venv/bin/activate
$ pip install -e .
$ pip install waitress
  • Start the application with the development configuration
$ pserve development.ini

Tests

  • For the testsuite with all versions use tox
  • If testing a single version use python setup.py test
  • The tests will require additional packages, which will be installed automatically
  • The integration tests will need a PHP version of OSCAd installed. As each run of the testsuite will issue >800 requests to that, so it is higly advisable to use a local instance for testing. The location of this instance has to be specfied in development.ini

Translations

To translate the application have a look at the locale directory in the packages, most notably oscad/locale.

The translation workflow is a standard gettext workflow eased by the integration with the Babel translation toolkit.

The translation toolchain should be with used with Python 2 (not Python 3), however the application itself also supports Python 3.

First we exctract translateable messages from the templates and code file. This updates the global translations template oscad/locale/oscad.pot.

$ python setup.py extract_messages

Then update all the existing language specific message catalogs, or only a single catalog:

$ python setup.py update_catalog

# or
$ python setup.py update_catalog -l fr

This places updated catalogs in the subdirectories in oscad/locale/. You can edit them with your favourite gettext editor or as plaintext files (you should know about the format then)

Now the updated catalogs can be compiled into binary files which can be read by the application:

$ python setup.py compile_catalog

It is also possible to create catalogs for new languages:

$ python setup.py init_catalog -l es

Theming

There are several ways to customize the appearance of the application via themes. A theme consists of a normal python module containing a set of static assets, template (-snippets) or translations. One theme is directly bundled with the application. It is located in the directory oscad_theme_basic/. To be recognized as a python module it has to contain a file __init__.py which can be empty.

Builtin templates and static assets can be overridden shipping a resource of the same name and type in a theme. For possible ways of customization look for places in the code where templates are loaded either via a template renderer or via template inclusion. When overriding translations make sure to use the correct gettext domain.

As themes are normal packages they don't have to be in the applications source tree to be used. Just install them into your virtualenv or put them on sys.path.

Themes are activated with the configuration directive themes. The plural form indicates, that it's possible to configure multiple cascading themes. The value of the configuration directive is a whitespace delimited list of theme names which should be importable. Otherwise an exception is thrown at startup.
