Find all the unique imports in your library, automatically, because who likes do it by hand? Keeping track of imports in a rapidly evolving library is a terrible chore for which I have great distaste.

depfinder is not yet on pypi. For now, clone it from github and install it:

git clone git@github.com:ericdill/depfinder
cd depfinder
python setup.py install

Then use it!

python -c "
import depfinder;
tups = list(depfinder.iterate_over_library('.'));
for tup in tups:
    print(tup)"

You should see

('setup', './setup.py', ImportCatcher: {'required': {'setuptools'}})
('test', './test.py', ImportCatcher: {'required': {'depfinder'}})
('depfinder', './depfinder.py', ImportCatcher: {'required': {'stdlib_list'}, 'builtin': {'__future__', 'ast', 'sys', 'os'}})

iterate_over_library is a function that yields tuples of module_name, full_path_to_module and ImportCatcher objects.

• module_name is the name of the module (i.e., the file name without the .py suffix)
• full_path_to_module is the full path to the file
• ImportCatcher is a data bucket for information that was obtained by rendering the module_name as an Abstract Syntax Tree (AST) and searching the tree for import nodes.
