Module contents:

• module_doc(module, *, sort_key=<function <lambda> at 0x10c5913a0>, filter_key=<function <lambda> at 0x10c591a80>, method_names=None): Fetch the docstrings from a module and assemble a MarkDown document.

  Parameters:

  • module: the module or module name to inspect
  • sort_key: optional key for sorting names in the documentation; default: name
  • filter_key`: optional test for a key used to select or reject keys to appear in the documentation
  • method_names: optional list of method names to document; the default is to document __init__, then CONSTANTS, the dunders, then other public names

• obj_docstring(obj): Return a docstring for obj which has been passed through stripped_dedent.

Release Log

Release 20260531: Some markup tweaks and a fix.

Release 20250426:

• module_doc: new doc_item inner function to format an item, now using a list instead of a heading - more compact and readable.
• module_doc: restore mangled command usage.
• module_doc: provide a short summary of every module top level name before the full docs.

Release 20241007:

• module_doc: for subclasses of cs.fsm.FSM embed an SVG state transition diagram.
• module_doc: put HTML named anchors on the headings.
• module_doc: use BaseCommand.extract_usage() with BaseCOmmand subclasses.

Release 20240709: module_doc: do not insert a BaseCommand usage into the docs, the BaseCommand.init_subclass will be doing that for us.

Release 20240630.1: module_doc: build the usage message from an instance of the baseCommand, needed since the last cs.cmdutils release.

Release 20240630: module_doc: insert the class usage message for subclasses of BaseCommand.

Release 20240422: module_doc: only list things in all if provided.

Release 20240412: module_doc: classes: MRO: suppress classes which are not immediate superclasses.

Release 20220311: module_doc: class members no longer rendered as headings, too verbose.

Release 20210306: Drop noise leaked into output.

Release 20210123:

• module_doc: include properties/descriptors.
• DISTINFO: this is not Python 2 compatible, drop tag.

Release 20200718:

• New is_dunder(name) function to test whether name is a dunder name.
• module_doc: new method_names parameter to report only specific attributes from a class - default is all public names and most dunder methods - things without docs are not reported.
• Assorted small changes.
