This site has been generated using Pelican 3.3 for over two years - and I finally found some time to upgrade to the current version of Pelican, 3.6.3. This is how I did the upgrade.

I decided to be lazy and do the upgrade in-place, instead of creating a new virtualenv and copying the content & settings over. Luckily, this worked out OK, after a bit of fiddling around.

I also decided, rather cavalierly, to upgrade all the packages ...

A dummy placeholder image, 200x200 pixels square.

This figure has automatic figure numbering.

I had a feature request for automatic figure numbering, like latex. I was revamping this plugin for Pelican 3.3 anyway - and this didn’t seem too hard - so I decided to add it.

So, the Better Figures & Images plugin now supports automatic figure numbering. To enable this for all posts, just add this to your config file:

FIGURE_NUMBERS = True

If you want to enable this per post, just add this to the metadata ...

There are quite a few changes in Pelican 3.3 - most of them minor, but a few which might mean making some changes to your site in order to upgrade. This is what I did to move my site from Pelican 3.2 to 3.3.

The change that had the biggest impact and took the most work was around image linking - caused by a combination of things. I think I was doing it wrong before and things changed in ...

I’ve recently been corresponding with Denny Dias, from Brazil, who’s converted his blog over to Pelican - and we’ve been helping each other out a bit with building themes and whatnot.

He’s written up his conversion & theme building process - and was generous enough to credit me after he borrowed some of my theme’s logic, from this blog’s GitHub repo.

As he’s such a nice guy - and as I’ve just borrowed his tagsort jinja ...

This is a Pelican plugin to calculate various statistics about a post and store them in an article.stats dictionary. You can see this in action in the sidebar on the left of this site.

Nice touch from medium.com - now available in Pelican.

I wanted to implement the nice little “X min read” thing from Medium - and it turned out that it was easy to provide a few other interesting stats at the same time, for people to use ...

How Figures & Images work in Pelican, by default

By default Pelican does a great job with figures and images, thanks to built-in support in ReStructuredText [1]. Pelican will turn this rst input:

.. figure:: {filename}/images/better-figures-images-plugin-for-pelican/dummy-200x200.png
    :align: right

    This is the caption of the figure.

    The legend consists of all elements after the caption. In this case, the legend consists of this paragraph.

into this HTML output:

<div class="figure align-right">
    <img alt="/static/images/dummy-200x200.png" src ...

As I mentioned previously, this site was put together using Pelican - a static site generator, written in Python.

Blueprint style diagram showing a brown Pelican, flying. The diagram point out it's Yellow Head, Large beak and pouch for fishing, long neck, white chest and grey body.

Pelecanus Occidentalis - the Brown Pelican.

Static site generators take your content, pour it into your templates and output the result as static pre-generated HTML, CSS, JS & image files. You can then just upload the resulting folder of output to your server and you’re done. All you ...

I’ve been meaning to consolidate my personal websites onto this domain for a long, long time. My original personal website, dflock.co.uk, started in the late nineties - and has been getting a bit long in the tooth of late.

Screenshot of the current version of the dflock.co.uk website homepage, at the time of publishing this post. It's kinda green and nineties looking.

Static text files - the gift that keeps on giving.

That site has been up, looking mostly like that, for ~15 years - with zero maintenance or downtime. Nice to know it’s still valid CSS 1.0 :)

When I created ...
