# RDFLib developers guide

## Introduction

This document describes the process and conventions to follow when developing RDFLib code.

Please be as Pythonic as possible (PEP 8).

Code will occasionally be auto-formatted using `autopep8` - you can also do this yourself.

Any new functionality being added to RDFLib should have doc tests and unit tests. Tests should be added for any functionality being changed that currently does not have any doc tests or unit tests. And all the tests should be run before committing changes to make sure the changes did not break anything.

If you add a new cool feature, consider also adding an example in `./examples`

## Running tests

Run tests with nose:

Specific tests can either be run by module name or file name. For example:

    $ python run_tests.py --tests rdflib.graph
    $ python run_tests.py --tests test/test_graph.py

## Writing documentation

We use sphinx for generating HTML docs, see Writing RDFLib Documentation

## Continous Integration

We used Travis for CI, see:

> https://travis-ci.org/RDFLib/rdflib

If you make a pull-request to RDFLib on GitHub, travis will automatically test you code.

## Compatibility

RDFLib>=3.X tries to be compatible with python versions 2.5 - 3

Some of the limitations we’ve come across:

> - Python 2.5/2.6 has no abstract base classes from collections, such `MutableMap`, etc.
> - 2.5/2.6 No skipping tests using `unittest`, i.e. `TestCase.skipTest` and decorators are missing => use nose instead
> - no `str.decode('string-escape')` in py3
> - no `json` module in 2.5 (install `simplejson` instead)
> - no `ordereddict` in 2.5/2.6 (install `ordereddict` module)
> - `collections.Counter` was added in 2.6

## Releasing

Set to-be-released version number in `rdflib/__init__.py`

Add `CHANGELOG` entry.

Commit this change, and tag it with:

    git tag -a -m 'tagged version' X.X.X

When pushing, remember to do:

    git push --tags

Upload tarball to pypi with:

    python setup.py sdist upload

Set new dev version number in the above locations, i.e. next release -dev: `8.9.2-dev` and commit again.
