pydoc2markdown 0.8.0

Convert Python docstrings to Markdown documentation.

PyDoc2Markdown

Convert Python docstrings into clean, structured Markdown documentation.

PyDoc2Markdown turns Python docstrings into plain Markdown that is easy to read, easy to commit, and easy to publish anywhere. Point it at your source tree and it can generate module docs, a navigation-ready docs directory, or a maintained API section inside your README.

It is built for projects that want documentation to stay close to the code without taking on a full documentation framework. The output works well on GitHub, GitLab, MkDocs, and any other Markdown renderer.

What you get:

• Plain .md files instead of a custom docs runtime
• Useful output with almost no setup
• A CLI for day-to-day use and a small library API for automation
• Features that help docs stay current: --check, --prune, README sync, navigation pages, and --report

A good fit for:

• Python libraries that want lightweight API docs in the repo
• Internal tools and services that keep docs next to the code
• Projects that want README API sections without manual copy-paste
• Teams that prefer Markdown files over framework-specific documentation stacks

Why PyDoc2Markdown?

Documentation generators like Sphinx are powerful but often come with noticeable setup: themes, conf.py, extensions, and custom builders to get the exact output you want. pdoc and mkdocstrings are lighter, but they still pull you toward a broader documentation stack.

PyDoc2Markdown takes a different approach: minimal setup, no framework lock-in, plain Markdown output. Point it at a Python project and get structured docs that work anywhere: GitHub, GitLab, MkDocs, or any Markdown renderer.

• No conf.py - works out of the box
• No framework lock-in - generates plain .md files
• Minimal dependencies - Jinja2 + docstring-parser
• Practical defaults - useful CLI output before you write any config

Features

• Docstring parsing - Extract Google and NumPy style docstrings, with basic reStructuredText field support via docstring-parser.
• Markdown generation - Produce clean Markdown files with customizable Jinja2 templates.
• README API sections - Create or update a generated API reference block in README files, in summary or detailed mode.
• Auto-generated index & TOC - Each module gets a Table of Contents; an index.md with package grouping is created automatically.
• Navigation layout - Generate a docs entrypoint with package pages and API files under api/.
• Output toggles - Control built-in TOC, source links, compact sections, class metadata, Public API, attributes, returns, raises, and member visibility from CLI or pyproject.toml.
• CI-friendly checks - Verify generated docs are up to date with --check.
• Coverage report mode - Inspect undocumented modules, classes, functions, exports, and parameter docs with --report.
• Managed cleanup - Preview or remove stale generated Markdown with --prune and --dry-run.
• Module filtering - Include or exclude source files with glob patterns.
• Parameter defaults - Show which function arguments are required or optional.
• Source links - Link generated classes, functions, and methods back to source code.
• Package grouping - Output files are organized into subdirectories matching the package structure.
• Built-in themes - Choose between default (detailed) and minimal themes, or supply your own template.
• CLI & API - Use via command line or import as a Python library.
• Recursive processing - Scan entire packages in one command.
• Type-aware - Respects type hints and annotations.
• Advanced constructs - Supports property, classmethod, staticmethod, dataclass, Enum, TypedDict, Protocol, ABC, Pydantic, and __all__.

Requirements

• Python >= 3.10
• Dependencies: Jinja2, docstring-parser
• Optional: watchdog (for --watch mode)

Installation

# Base installation
pip install pydoc2markdown

# With file watcher support
pip install pydoc2markdown[watch]

Visual Tour

Here is the kind of navigation-first Markdown output the project generates from the included sample package:

Try It In 30 Seconds

Clone the repository and run PyDoc2Markdown against the included sample project:

pydoc2markdown examples/sample_project/src --recursive --nav --readme \
  --readme-path examples/sample_project/README.md \
  -o examples/sample_project/docs

That one command updates the sample project's README API block and creates a navigation-first docs layout you can inspect immediately:

examples/sample_project/
|-- README.md
|-- src/shop_demo/
`-- docs/
    |-- index.md
    |-- shop_demo.md
    `-- api/shop_demo/
        |-- inventory.md
        `-- orders.md

Sample Project

The sample project is a tiny shop package with dataclasses, an enum, typed functions, properties, and Google-style docstrings. It is the fastest way to understand what PyDoc2Markdown actually produces in a real repo layout.

You can inspect the whole workflow side by side:

• source code
• generated docs index
• README API section

You can also create the same kind of demo project locally:

pydoc2markdown --demo

By default this writes to pydoc2markdown-demo/. Use --demo-output to choose another directory. Existing non-empty directories are not overwritten.

Before And After

This is the same idea in a tighter input -> output view:

Start with normal Python code and docstrings:

def calculate_total(items: list[Product], discount: float = 0.0) -> float:
    """Calculate the discounted order total.

    Args:
        items: Products to include in the total.
        discount: Discount ratio between 0 and 1.

    Returns:
        Total price after discount.

    Raises:
        ValueError: If discount is outside the accepted range.
    """

PyDoc2Markdown turns it into Markdown with headings, parameter tables, return types, and raised exceptions:

### `calculate_total`

Calculate the discounted order total.

**Parameters:**

| Name | Type | Default | Description |
|------|------|---------|-------------|
| `items` | `list[Product]` | *required* | Products to include in the total. |
| `discount` | `float` | `0.0` | Discount ratio between 0 and 1. |

**Returns:** `float`
Total price after discount.

**Raises:**
- `ValueError`: If discount is outside the accepted range.

Recipes

Here are a few practical ways teams tend to use PyDoc2Markdown.

Keep API docs in docs/

Generate a navigation-ready docs tree for a package:

pydoc2markdown src/my_package --recursive --nav -o docs

This works well when you want browsable Markdown pages in the repository, MkDocs, or another lightweight docs site.

Keep a README API block in sync

Update a generated API section without touching the rest of the README:

pydoc2markdown src/my_package --recursive --readme --readme-path README.md

This is a good fit for small libraries that want usage notes and API reference in one file.

Use --readme-mode detailed when you want a richer embedded API section:

pydoc2markdown src/my_package --recursive --readme --readme-mode detailed

Gate docs in CI

Fail CI when generated docs are missing, stale, or no longer match the source tree:

pydoc2markdown src/my_package --recursive --nav --readme --check -o docs

Pair this with --prune in local development to keep generated docs tidy after renames and deletions.

Generate docs only for the public surface

Focus on selected packages and skip internal modules:

pydoc2markdown src/my_package --recursive \
  --include "api/*,models/*" \
  --exclude "*/internal/*,*_test.py" \
  -o docs

This is useful when your source tree is larger than the documentation surface you actually want to publish.

  --no-show-raises \
  -o docs

# Check whether generated docs are current without writing files
pydoc2markdown src/my_package --recursive --nav --check -o docs

# Print a documentation coverage report
pydoc2markdown src/my_package --recursive --report

pydoc2markdown src/my_package --recursive --report --report-format json

# Save the report as a CI artifact while still printing it to stdout
pydoc2markdown src/my_package --recursive --report \
  --report-format json \
  --report-output reports/doc-coverage.json

# Preview stale generated Markdown files before removing them
pydoc2markdown src/my_package --recursive --prune --dry-run -o docs

Configuration priority: CLI flags > [tool.pydoc2markdown] in pyproject.toml > built-in defaults.

Configuration

You can initialize default configuration with:

pydoc2markdown --init

This creates or appends a [tool.pydoc2markdown] section in pyproject.toml. If the section already exists, it is left unchanged.

You can also set default values manually in your pyproject.toml:

[tool.pydoc2markdown]
output = "docs"
theme = "default"
recursive = true
show_toc = true
show_source_links = true
compact_sections = false
show_class_metadata = true
show_public_api = true
show_attributes = true
show_returns = true
show_raises = true
show_private_members = false
show_dunder_members = false
public_only = false
member_include = ["Client", "Client.run", "public_*"]
member_exclude = ["Client.helper", "_debug"]
readme_mode = "summary"
readme_title = "API Reference"

Any values set here serve as defaults and can be overridden by CLI flags.

Module Filtering

Use --include and --exclude with --recursive to control which Python files are documented:

pydoc2markdown src/my_package --recursive --exclude "tests/*,*/internal/*,*_private.py"

Patterns use standard shell-style globs and are matched against paths relative to the scanned source root. Patterns without a directory separator also match file names in any package directory, so conftest.py or *_test.py work as convenient basename filters.

When both flags are used, PyDoc2Markdown applies --include first and then removes anything matched by --exclude:

pydoc2markdown src/my_package --recursive --include "api/*,core/*" --exclude "*/generated.py"

Member Filtering

Use member filtering when you want to narrow documentation inside each module, not just choose which files are parsed.

--public-only is the highest-signal option for library projects. When a module defines __all__, PyDoc2Markdown keeps the exported top-level classes and functions in docs, README summaries, single-file output, navigation docs, and --report:

pydoc2markdown src/my_package --recursive --public-only -o docs

Private names such as _helper and _debug are hidden by default. Dunder members such as __repr__ are hidden by default as well. If you want to expose those internals in generated docs, opt in explicitly:

pydoc2markdown src/my_package --recursive \
  --show-private-members \
  --show-dunder-members \
  -o docs

These controls affect:

• generated module docs
• navigation docs
• single-file output
• README API sections
• --report

That keeps the visible docs surface and the reported coverage surface aligned. For class docs, the same filtering rules also apply to attribute tables and Pydantic field tables.

When you need more precision, use --member-include and --member-exclude. Patterns are matched against a few useful forms for the same object:

• bare names like helper or Widget
• class-qualified names like Client.run
• module-qualified names like my_pkg.client.helper
• fully qualified method names like my_pkg.client.Client.run

For example:

pydoc2markdown src/my_package --recursive \
  --member-include "Client,Client.run,public_*" \
  --member-exclude "Client.helper,_debug,*.backup" \
  -o docs

This is applied after file-level include/exclude and alongside public_only, private-member, and dunder-member controls.

Source Links

Use --source-repo to add GitHub source links next to generated class, function, and method headings:

pydoc2markdown src/my_package --recursive --source-repo user/repo -o docs

This expands to a GitHub URL template using the main branch:

https://github.com/user/repo/blob/main/{path}#L{line}

For GitLab, another branch, or a custom host, pass the full template with --source-link:

pydoc2markdown src/my_package --recursive \
  --source-link "https://gitlab.com/user/repo/-/blob/develop/{path}#L{line}" \
  -o docs

Available template variables are {path} for the source-root-relative Python file path, {file} for the filename, and {line} for the 1-indexed definition line.

Output Toggles

PyDoc2Markdown's built-in renderer can be trimmed without writing a custom template. You can set these toggles per run or keep them in [tool.pydoc2markdown].

• show_toc
• show_source_links
• compact_sections
• show_class_metadata
• show_public_api
• show_attributes
• show_returns
• show_raises
• show_private_members
• show_dunder_members
• public_only
• member_include
• member_exclude

For example, this keeps parameter tables but removes Public API, Returns, and Raises blocks from generated docs:

pydoc2markdown src/my_package --recursive \
  --no-show-public-api \
  --no-show-returns \
  --no-show-raises \
  -o docs

README API Sections

Use --readme to create or update a generated API reference in your README:

pydoc2markdown src/my_package --recursive --readme

By default, PyDoc2Markdown updates README.md. Use --readme-path to target a different file:

pydoc2markdown src/my_package --recursive --readme --readme-path docs/index.md

summary is the default README mode and is optimized for a lightweight module overview. It now includes short module summaries, compact counts, and one-line class/function previews. When a module defines __all__, the summary also prioritizes those exported names as the README-facing public API. When README generation runs alongside docs generation, module headings also link back to the generated Markdown pages automatically. For projects with multiple package groups, summary mode also adds lightweight package sections and uses package __init__ docstrings as short intros when available. It also adds an overview line and quick links for the generated module set. Those quick links point to generated docs when available, and otherwise fall back to internal README anchors. Use --readme-mode detailed for a richer embedded API section that reuses the built-in Markdown renderer without per-module TOCs.

Use --readme-title when the generated section should appear under a different heading:

pydoc2markdown src/my_package --recursive --readme --readme-title "Developer API"

When the file already contains PyDoc2Markdown markers, only the generated block between the markers is replaced:

## API Reference

<!-- pydoc2markdown:start -->
<!-- pydoc2markdown:end -->

If the markers are missing, a new ## API Reference section is appended. If the README does not exist, it is created.

Navigation Docs Layout

Use --nav when you want a docs directory that is ready to browse from a single entrypoint:

pydoc2markdown src/my_package --recursive --nav -o docs

This creates a layout like:

docs/
|-- index.md
|-- modules.md
`-- api/
    |-- package.md
    `-- utils.md

The root index.md links to package landing pages and every generated API page. Use --api-dir to change where module pages are written:

pydoc2markdown src/my_package --recursive --nav --api-dir reference -o docs

CI Checks

Use --check in CI to fail when generated documentation is missing or stale:

pydoc2markdown src/my_package --recursive --nav --readme --check -o docs

The command compares the files PyDoc2Markdown would generate with the files already on disk. It exits with 0 when docs are current and 1 when any generated output needs to be updated. It does not write files in check mode.

--check works with normal multi-file output, --nav, --single-file, and README API sections. It cannot be combined with --watch.

Documentation Coverage Report

Use --report when you want a quick documentation audit without writing any Markdown files:

pydoc2markdown src/my_package --recursive --report

The report prints totals plus findings for:

• modules without docstrings
• classes without docstrings
• functions without docstrings
• undocumented __all__ exports
• parameters missing descriptions

The text report also includes an overall coverage percentage and per-category coverage breakdown so you can see where gaps are concentrated.

By default, --report is analysis-only and exits successfully when the report is produced. Use --fail-on when you want selected findings to fail CI:

pydoc2markdown src/my_package --recursive --report --fail-on modules,params

Use --fail-on any to fail on any non-zero finding category.

Use --fail-under when you want to enforce a minimum overall coverage target:

pydoc2markdown src/my_package --recursive --report --fail-under 95

Use --report-summary-only when you want compact CI logs that still show coverage totals and category counts:

pydoc2markdown src/my_package --recursive --report --report-summary-only

Use --report-categories when you want to focus the report on a smaller slice of documentation debt:

pydoc2markdown src/my_package --recursive --report --report-categories modules,params

For automation, JSON output is also available:

pydoc2markdown src/my_package --recursive --report --report-format json

To keep the report as a build artifact, add --report-output:

pydoc2markdown src/my_package --recursive --report \
  --report-format json \
  --report-output reports/doc-coverage.json

Prune Stale Docs

Use --prune to remove stale generated Markdown files that were tracked by PyDoc2Markdown in a previous run but are no longer expected for the current source tree:

pydoc2markdown src/my_package --recursive --prune -o docs

To preview the cleanup first, add --dry-run:

pydoc2markdown src/my_package --recursive --prune --dry-run -o docs

--prune only affects generated Markdown files recorded in the PyDoc2Markdown manifest. It does not try to delete unrelated hand-written Markdown files that may live in the same docs directory.
