Sphinx llms.txt Generator ========================= A `Sphinx`_ extension that generates a summary ``llms.txt`` file, written in Markdown, and a single combined documentation ``llms-full.txt`` file, written in reStructuredText. |PyPI version| |Conda Version| |Downloads| |Parallel Safe| |GitHub Stars| Demo ---- This Sphinx project's `llms.txt`_ and `llms-full.txt`_ files as an example of the default output format. Alternative :ref:`output formats ` are also available. For example: `Markdown`_ and `reStructuredText`_. Highlights ---------- **Zero Configuration** Add the extension to your ``conf.py`` and you're done. The extension automatically collects your documentation and generates both ``llms.txt`` and ``llms-full.txt`` during your normal Sphinx build. **Intelligent Content Processing** Automatically resolves ``include`` directives, transforms relative paths, and handles your documentation structure without manual intervention. **Customizable When Needed** Filter content, include source code files, or integrate with alternative output formats like Markdown for even better LLM compatibility. See :doc:`getting-started` for output format options and :doc:`configuration-values` for all settings. .. seealso:: For better default output without configuration, see `sphinx-llm `_ from NVIDIA. sphinx-llms-txt is best when customized with alternative output formats, content filtering, or source code inclusion. .. toctree:: :maxdepth: 2 getting-started advanced-configuration configuration-values contributing changelog .. _llms.txt: https://sphinx-llms-txt.readthedocs.io/en/latest/llms.txt .. _llms-full.txt: https://sphinx-llms-txt.readthedocs.io/en/latest/llms-full.txt .. _Markdown: https://sphinx-llms-txt.readthedocs.io/en/latest/llms.md.txt .. _reStructuredText: https://sphinx-llms-txt.readthedocs.io/en/latest/llms.rst.txt .. _Sphinx: http://sphinx-doc.org/ .. |PyPI version| image:: https://img.shields.io/pypi/v/sphinx-llms-txt.svg :target: https://pypi.python.org/pypi/sphinx-llms-txt :alt: Latest PyPi Version .. |Conda Version| image:: https://img.shields.io/conda/vn/conda-forge/sphinx-llms-txt.svg :target: https://anaconda.org/conda-forge/sphinx-llms-txt :alt: Latest Conda Version .. |Downloads| image:: https://static.pepy.tech/badge/sphinx-llms-txt/month :target: https://pepy.tech/project/sphinx-llms-txt :alt: PyPi Downloads per month .. |Parallel Safe| image:: https://img.shields.io/badge/parallel%20safe-true-brightgreen :target: # :alt: Parallel read/write safe .. |GitHub Stars| image:: https://img.shields.io/github/stars/jdillard/sphinx-llms-txt?style=social :target: https://github.com/jdillard/sphinx-llms-txt :alt: GitHub Repository stars Getting Started =============== Installation ------------ Directly install by using: .. tab:: via pip .. code-block:: bash pip install sphinx-llms-txt .. tab:: via conda: .. code-block:: bash conda install -c conda-forge sphinx-llms-txt Usage ----- Add the extension to your Sphinx configuration (``conf.py``): .. code-block:: python extensions = [ 'sphinx_llms_txt', ] After the HTML finishes building, **sphinx-llms-txt** will output the location of the output files:: sphinx-llms-txt: Created /path/to/_build/html/llms-full.txt with 45 sources and 6879 lines sphinx-llms-txt: created /path/to/_build/html/llms.txt .. _choosing-output-format: Choosing an Output Format ------------------------- By default, **sphinx-llms-txt** requires no additional configuration and links to raw reStructuredText source files created by the HTML builder.

[#rendered] Directives are expanded and processed before output, so content like autodoc docstrings will be included. Advanced Configuration ====================== This page covers advanced configuration options for the sphinx-llms-txt extension. .. _customizing_llms_files: Customizing the LLMs Files ^^^^^^^^^^^^^^^^^^^^^^^^^^ By default, the extension generates two files: 1. ``llms.txt`` - A summary file in Markdown format 2. ``llms-full.txt`` - A complete documentation file in reStructuredText format You can customize these files in several ways: .. _changing_filenames: Changing Filenames ~~~~~~~~~~~~~~~~~~ You can change the default filenames by setting these values in your ``conf.py``: .. code-block:: python llms_txt_filename = "custom-summary.txt" llms_txt_full_filename = "custom-docs.txt" .. _disabling_file_generation: Disabling File Generation ~~~~~~~~~~~~~~~~~~~~~~~~~ If you only want one of the files, you can disable generation of the other: .. code-block:: python # Disable summary file llms_txt_file = False # Disable full documentation file llms_txt_full_file = False .. _custom_summary: Adding a Custom Summary ~~~~~~~~~~~~~~~~~~~~~~~ The summary file can include a custom description of your project: .. code-block:: python llms_txt_summary = """ This documentation explains how to use MyProject to build amazing applications. The project provides a comprehensive API for handling data processing and visualization. """ .. note:: The summary can span multiple lines and will be properly formatted in the output file. .. _custom_title: Custom Title ~~~~~~~~~~~~ By default, the project name from Sphinx is used as the title in ``llms.txt``. You can override this: .. code-block:: python llms_txt_title = "My Custom Project Documentation" .. _handling_large_documentation: Handling Large Documentation ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ For very large documentation sets, generating the full documentation file might exceed reasonable size limits. You can set a maximum line count and control what happens when that limit is exceeded: .. code-block:: python llms_txt_full_max_size = 10000 # Maximum 10,000 lines llms_txt_full_size_policy = "warn_skip" # Default behavior The ``llms_txt_full_size_policy`` setting controls both the log level and action taken when the size limit is exceeded. It uses the format ``"_"``: **Log levels:** - ``warn``: Log as a warning (default) - ``info``: Log as informational message **Actions:** - ``skip``: Don't create the file (default) - ``keep``: Create the file anyway, ignoring the size limit - ``note``: Create a placeholder file explaining why the full file wasn't generated .. tip:: Use :ref:`excluding_content` to remove less relevant pages and reduce the file size. .. _custom_directive_handling: Custom Directive Handling ^^^^^^^^^^^^^^^^^^^^^^^^^ .. _path_resolution: Path Resolution ~~~~~~~~~~~~~~~ The extension resolves paths in the common directives ``[ 'image', 'figure']`` by default. You can add custom directives to this list: .. code-block:: python llms_txt_directives = [ "my-custom-image-directive", "another-directive-with-paths", ] This ensures that paths in your custom directives are properly resolved in the generated files. .. _excluding_content: Excluding Content ^^^^^^^^^^^^^^^^^ There are several ways to exclude content from the generated ``llms-full.txt`` file: .. _global_exclusion: Global Page Exclusion ~~~~~~~~~~~~~~~~~~~~~~ You can exclude specific pages from being included in the generated files: .. code-block:: python llms_txt_exclude = [ "search", # Exclude the search page "genindex", # Exclude the index page "private_*", # Exclude all pages starting with 'private_' ] This is useful for excluding auto-generated pages, indexes, or content that isn't relevant for LLM consumption. It can also be used to reduce the size of llms-full.txt. .. _page_level_ignore: Page-Level Ignore Metadata ~~~~~~~~~~~~~~~~~~~~~~~~~~~ You can exclude individual pages by adding metadata at the top of any reStructuredText file: .. code-block:: restructuredtext :llms-txt-ignore: true Page Title ========== This entire page will be excluded from llms-full.txt When this metadata is present, the entire page is skipped during processing. .. _block_level_ignore: Block-Level Ignore Directives ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ You can exclude specific sections within a page using ignore directives: .. code-block:: restructuredtext Page Title ========== This content will be included in llms-full.txt. This content will be included again. Block-level ignores can be useful for: - Removing internal notes or TODOs - Hiding implementation details while keeping user-facing documentation .. note:: - Multiple ignore blocks can be used within the same file - Ignore directives work with any indentation level .. _including_code_files: Including Source Code Files ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ You can include source code files from your project at the end of :confval:`llms_txt_full_filename`. Use include/exclude syntax to precisely control which files are included: .. code-block:: python llms_txt_code_files = [ "+:src/**/*.py", # Include all Python files in src "-:src/**/__pycache__/**", # Exclude Python cache files ] Pattern syntax: - **+:pattern**: Include files matching the pattern. Processed first to collect matching files. - **-:pattern**: Exclude files matching the pattern. Applied to filter out unwanted files. Code files are processed as follows: - **Glob patterns**: Use standard glob patterns (``*``, ``**``, ``?``) to match files - **Relative paths**: Patterns are resolved relative to your Sphinx source directory - **Formatting**: Each file is presented with a title and syntax-highlighted code block .. _customizing_code_paths: Customizing Code File Paths ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ By default, the extension automatically detects the relative path from your Sphinx source directory to the git root and strips that prefix from displayed file paths. You can customize this behavior: .. code-block:: python # Manually specify base path to strip llms_txt_code_base_path = "../../" # Disable path stripping entirely llms_txt_code_base_path = "" This helps create cleaner, more readable file paths in the generated documentation. .. _using_html_baseurl: Using HTML Base URL ^^^^^^^^^^^^^^^^^^^ If you want to include absolute URLs for resources in your documentation, you can use Sphinx's built-in ``html_baseurl`` configuration: .. code-block:: python html_baseurl = "https://example.com/docs/" When this option is set, all resolved paths in directives will be prefixed with this URL, creating absolute paths in the generated files. .. _customizing_uri_links: Customizing URI Links in llms.txt ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ By default, the ``llms.txt`` file links to source files in the ``_sources`` directory when available, falling back to HTML pages when sources aren't available. You can customize this behavior using URI templates with :confval:`llms_txt_uri_template`: .. code-block:: python # Default: Link to source files, if _sources exists llms_txt_uri_template = "{base_url}_sources/{docname}{suffix}{sourcelink_suffix}" # Default: Link to HTML pages instead, if _sources doesn't exist llms_txt_uri_template = "{base_url}{docname}.html" # Manual: Link to a custom markdown build llms_txt_uri_template = "{base_url}{docname}.md" .. _available_template_variables: Available Template Variables ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Your URI template can use the following variables: - ``{base_url}`` - The base URL from ``html_baseurl`` configuration (includes trailing slash) - ``{docname}`` - The document name (e.g., ``index``, ``guide/intro``) - ``{suffix}`` - The source file suffix (e.g., ``.rst``, ``.md``) - may be empty if no source file exists - ``{sourcelink_suffix}`` - The suffix from ``html_sourcelink_suffix`` configuration (e.g., ``.txt``) .. tip:: Instead of using the default of linking to ``_sources``, you can generate Markdown and/or reStructuredText files from your documentation and link to those in ``llms.txt``. See :ref:`cmake_workflow` for an example of building both HTML and Markdown and/or reStructuredText in parallel. Note that ``_sources`` is still needed for ``llms-full.txt`` at this time. .. _cmake_workflow: CMake Workflow ^^^^^^^^^^^^^^ This project uses CMake to orchestrate documentation builds across multiple output formats, serving as a simple demo of the functionality. This approach enables parallel builds and integrates well with CI/CD platforms like Read the Docs. Building multiple formats allows you to compare what works best for your docs, as well as allows users to choose which format to feed to their LLM. Use :confval:`llms_txt_uri_template` to configure links to point to your preferred format.
