Using Sphinx to build a Logbook

In my last post I wrote about using Sublime Text to write a logbook of activities at work. This time I’m going to quickly explain how I build that into a local website using Sphinx.

Why Sphinx?

I first started using Sphinx to build documentation for my slowly developing WIAT software package. With it, I could write comprehensive docstrings in my code and have the entire package automatically documented as HTML among other formats.

Sphinx is widely used for Python documentation and once I got started using it, it seemed like a good tool to build my logbook as well, rather than learning another.

Installing Sphinx in Windows

As I wrote in my last post, installing non-corporate software is more difficult than it used to be. Fortunately, most Python software can still be installed. Even better, however, is installing Anaconda, which produces a locally installed Python environment that includes almost 200 packages, including Sphinx.

Installing Sphinx, therefore, was simply a matter of installing Anaconda. Doing so adds Python to the Windows environment path, so the system will recognise python as an executable program.


I use a chronological structure for my logbook, not differentiating between individual projects. It reflects the way I take notes manually and is basically just a diary.

Each week has its own reStructuredText file, and within that the structure is divided into days and topics.

Sphinx uses an index file to structure a table of contents, so mine might look like this:

My Work Log
This is the index of my work log.

.. Table of contents.
.. toctree::
    :maxdepth: 2

* :ref:`genindex`
* :ref:`search`

Once a month is complete, I produce a sub-index of the weeks in that month (such as 201401), and after a year these go into a folder for the whole year. Meanwhile, the weeks of the current month are listed directly in the index file.

Building the pages

When you run the sphinx-quickstart script, you can specify that Makefiles are produced (a batch file in the case of Windows). The idea then is that all you have to do is run make html on a command line to build the set of HTML files.

Using Sublime Text, it’s possible to simplify that by using a build system. Build systems allow you to specify a series of commands to be executed from within Sublime Text itself.

I used to simply run make html as a build system, but after breaking it somehow, I invoke the Sphinx command directly. Build systems are written in JSON, and look something like this:

    "name": "Build work log",
    "working_dir": "C:\\Users\\pestrickland\\work_log",
    "cmd": ["sphinx-build.bat",

Future improvements and other applications


The system I described has worked well for me so far, but it is still quite manual. I still create a new file every week and populate it with date information. And I still manually update my index file and move files around into month and year folders.

Eventually I would like to automate the majority of this process, so that building the latest logbook each week also moves files around and updates the index where necessary.

A new theme

Sphinx supports theming, a nice example of which is shown on Read the docs. So far I have only used one of the default themes, but it would be nice to customise the look and feel of my logbook, to make it feel more like mine.

An online handbook

At work we often talk about producing a handbook of our internal processes, procedures and methods to estimating effort, assessing systems and writing reports. But not much happens beyond that talk.

A few years ago I started running a local MediaWiki site that I wanted to become a handbook. It proved very useful, but more of an evidence database than a handbook. It was also difficult to share as it was not installed onto the corporate network and wikis are not in favour with the IT decision-makers.

Using Sphinx could provide a simpler manual. Source content could be written and shared as with any other document, and the whole thing could then be built into a set of HTML pages, a single HTML file or even a PDF document. It’s something that I haven’t thought through in much detail so far, but I think it might be worth a shot.
