sphinx-sql 1.0.3

Sphinx extension for autodoc of SQL files.

Introduction

sphinx-sql is a Sphinx documentation extension for building documentation from SQL source files.

* Do you live in a bottomless pit of dispair with “Living documents” in Sharepoint.

* Have you had to troubleshoot a problem and someone has reorganized the documentation tree in Sharepoint?

* Has your company let PMs loose on projects with no idea how to version documentation, so now you have copies of entire doc trees in Sharepoint?

* Do you work on a database first development project?

* Do you look at auto documentation packages and cry siliently because no one cares about DB first development?

* Don’t you wish you could maintain your project documentation with your code base, so you can check out and build the documents anytime you need them?

Having found nothing in the while that could help solve the db first problem, I’ve written sphinx-sql.

The goal of sphinx-sql is to provide an autodoc type module for database first development.

With a bit of standarization of comments in the top of the sql source files, we can maintain documentation that follows the code base.

This implimentation is tested against Greenplum / Postgres, those are the databases I work with on a daily basis. If you want to extend functionality, have a quick look at the contrib section of this document.

Installation

Install from PyPI:

pip install sphinx-sql

Configuration

Configuring Sphinx

In your conf.py for Sphinx enable the extension:

extensions = [
'sphinx_sql.sphinx_sql',
]

Configure toctree

Create a new rst file (we’ll call it autosql.rst) and include it in your toc-tree.

.. toctree::
:maxdepth: 2
:caption: Navigation:

autosql

Configure rst

Add the directive with a relative path from your document build folder to the root of your SQL source in the autosql.rst file.

SQL Documentation
^^^^^^^^^^^^^^^^^

.. autosql::
    :sqlsource: ../../SQL

Add SQL Comments

sphinx-sql recursively looks for all .sql files under the configured sqlource path.

It will extract the first block comment out of each file as well as important

object creatation lines such as CREATE TABLE / VIEW / FUNCTION / LANGUAGE etc.

Comments should adhear to the following formats, otherwise the regex searches will not find the appropriate blocks

Pipe delimiters are used in Parameters, Dependent Objects and Change Log files to create table rows in the documents, spaces don’t matter; everything else is free form text and should appear as you write it.
