haystack-pydoc-tools

---

Tool to generate Docusaurus-compatible Markdown API references from Python docstrings. It uses griffe to parse source code and griffe2md to render the output.

Installation

pip install haystack-pydoc-tools

Usage

The tool reads YAML configuration files and generates Markdown API docs.

Process a single config file:

haystack-pydoc config.yml [output-directory]

Process a directory of config files (in parallel):

haystack-pydoc pydoc/ output/

A pydoc-markdown alias is also available for backward compatibility.

Output behavior

Each config must specify a filename. By default, the file is written in the current working directory; if an output directory is provided, the file is written there instead.

Configuration

Each .yml file describes which modules to document and how to render the output.

Minimal example

loaders:
  - search_path: [src]
    modules:
      - haystack.components.generators.chat.openai
      - haystack.components.generators.chat.azure
renderer:
  title: Generators
  id: generators-api
  description: Enables text generation using LLMs.
  filename: generators_api.md

Full example

loaders:
  - search_path: [../src]
    modules:
      - haystack.components.generators.chat.openai
      - haystack.components.generators.chat.azure
processors:
  - type: filter
    documented_only: false    # include objects without docstrings
    skip_empty_modules: false  # keep modules even if they have no content
renderer:
  title: Generators API
  id: generators-api
  description: Enables text generation using LLMs.
  filename: generators_api.md

When the processors section is omitted, defaults apply: documented_only: true, skip_empty_modules: true.

Legacy example

The tool also accepts the older pydoc-markdown-style configs. Most fields are ignored but don't cause errors.

loaders:
  - type: haystack_pydoc_tools.loaders.CustomPythonLoader  # ignored
    search_path: [../src]
    modules:
      - haystack.components.generators.chat.openai
      - haystack.components.generators.chat.azure
    ignore_when_discovered: ["__init__"]  # ignored
processors:
  - type: filter
    expression:              # ignored
    documented_only: true
    do_not_filter_modules: false  # ignored
    skip_empty_modules: true
  - type: smart    # ignored
  - type: crossref  # ignored
renderer:
  type: haystack_pydoc_tools.renderers.DocusaurusRenderer  # ignored
  title: Generators API
  id: generators-api
  description: Enables text generation using LLMs.
  markdown:
    descriptive_class_title: false   # ignored
    classdef_code_block: false       # ignored
    descriptive_module_title: true   # ignored
    add_method_class_prefix: true    # ignored
    add_member_class_prefix: false   # ignored
    filename: generators_api.md
