Instead of returning tuples with fully expanded scopes return walker instances that internally know how to avoid recomputing the visible scopes (they do this by caching each visibility level and looking in the local cache before computing the scope and storing it in the cache). This makes the usage more uniform and avoids returning different items depending on what is found; making the code easier to follow and understand. Also makes the scope walker call to '_extract_atoms' to go via a static method so that if it is ever desired to alter what '_extract_atoms' does it can be more easily done (using standard inheritance).

Testing and requirements
Requirements
Because this project has many optional (pluggable) parts like
persistence backends and engines, we decided to split our requirements
into three parts: - things that are absolutely required (you can't use
the project without them) are put into requirements-pyN.txt
(N being the Python major version number used to
install the package). The requirements that are required by some
optional part of this project (you can use the project without them) are
put into our tox.ini file (so that we can still test the
optional functionality works as expected). If you want to use the
feature in question (eventlet or the
worker based engine that uses kombu or the sqlalchemy persistence backend or
jobboards which have an implementation built using kazoo ...), you should add that
requirement(s) to your project or environment; - as usual, things that
required only for running tests are put into
test-requirements.txt.
Tox.ini
Our tox.ini file describes several test environments
that allow to test TaskFlow with different python versions and sets of
requirements installed. Please refer to the tox documentation to understand how
to make these test environments work for you.
Developer documentation
We also have sphinx documentation in docs/source.
To build it, run:
$ python setup.py build_sphinx
