This is 'pydoctor', an API documentation generator that works by static analysis.

It was written primarily to replace epydoc for the purposes of the Twisted project as epydoc has difficulties with zope.interface. If it happens to work for your code too, that's a nice bonus :)

pydoctor puts a fair bit of effort into resolving imports and computing inheritance hierarchies and, as it aims at documenting Twisted, knows about zope.interface's declaration API and can present information about which classes implement which interface, and vice versa.

The default HTML generator requires Twisted.

There are some more notes in the doc/ subdirectory.

Tox development environment

Since Python 3 is not yet supported, you the case in which your default tox runs with Python 3, call the tox as:

python2 -m tox -e pyflakes

Sphinx Integration

HTML generator will also generate a Sphinx objects inventory using the following mapping:

  • packages, modules -> py:mod:
  • classes -> py:class:
  • functions -> py:func:
  • methods -> py:meth:
  • attributes -> py:attr:

Configure Sphinx intersphinx extension:

intersphinx_mapping = {
'pydoctor': ('http://domain.tld/api', None),


Use external references:

:py:func:`External API <pydoctor:pydoctor.model.Documentable.reparent>`


It can link to external API documentation using Sphinx objects inventory using the following cumulative configuration option:


Releasing a new package

Releasing a new version is done via Travis-CI. First commit the version update to master and wait for tests to pass. Create a tag on local branch and then push it:

git tag 1.2.3
git push --tags
