I' writing a new extension for Sphinx as a domain offering multiple directives, roles and indices for the hardware description language VHDL. This extension shall be able to auto document language constructs. In VHDL, we have e.g. entities/architectures or packages/package bodies. These could be documented as pairs in individual docutils documents, so each language construct has an individual URL (or page in PDF) in the documentation.
I'm looking for a solution to create new documents in Sphinx/docutils. According to the docutils API description, a document is the root element to a doctree (documentation tree). According to the Sphinx documentation, directives are items in the doctree that get consumed and can emit new nodes to the surrounding doctree. So it's a translation/replacement approach.
Non of the documentation seams to offer a way to create new document.
Looking at the autodoc
extensions, there are 2 sides. There is sphinx.ext.autodoc
coming with Sphinx. It offers .. auto***
directives to automatically document Python language constructs. It requires a user to place dozens to hundreds of auto-directives into the ReStructured Text. Of cause it automatically document e.g. classes or modules, but for a huge project it's a lot of work.
In addition, there is autoapi, which reads the Python code for a given package or module and generates ReST files on the fly when Sphinx is loaded. Then these files - containing auto-directives - are processed.
As I understand, autoapi workaround the problem of creating now docutils documents, by writing ReST files, so Sphinx generates document instances with a doctree, and then autodoc from Sphinx jumps in and replaces them with content from doc-strings.
So my questions after all investigations I did so far:
- How can I create docutils or Sphinx document to get a HTML file per item I want to auto document?
- Or do I always need to do a hack like autoapi from Carlos Jenkins and create ReST files as dummies or with auto directives, so I can use the replacement capabilities of Sphinx/autodoc from directive to documentation nodes?
Why don't I like the autoapi approach? I have parse VHDL files as input in form of a Code Document Object Model (CodeDOM). I don't want to serialize parse VHDL file into ReST, to parse it again, construct again a model of my source files, so I can then translate to documentation nodes like sections, paragraphs and lists.
I have all available to generate doc-nodes for docutils, but I need multiple documents, so I can distribute the content to hundreds of documentations file (HTML files).
