I think I'm ready to mark my second pelican theme 1.0 as "Feature Complete" today! I started off with -what I thought- a simple premise of having a site site took a lot longer than I expected but I'm pretty happy with the site for now. But before I tag it and start working on 2.0, I want to go over what I've done so far.

The first thing I started researching was how to make the site parsable by webcrawlers. Although it's a personal blog, I wanted people to be able to find the content easily.


OpenGraph was the first thing that I came across and appealed to me the most because it's the preferred way of parsing data for Twitter1.

I found it especially rewarding that the tags are also parsed by facebook and my new favorite social network slack.

One of the technical difficulties that I ran into when adding OpenGraph tags was adding the images. The specification for OpenGraph states that images to be used need to be added as meta data in the head of the html. This can be a pain as the other data like title and date can be pulled from the article itself and I didn't want to go through all my old posts to add image meta data.

Luckily, the github user WhiskyEchoBravo had a project that searched the content of the post for images and added the first to the list of tags. I'm a little proud that I helped with issues with pages.

Afterwards, I did run into some frustration when the images that I added to posts wouldn't be as big as I expected.

Ultimately, I think it's because of the mixing and matching of having OpenGraph and twitter specific tags and was solved it by making sure I used the following for my twitter card.

<meta name="twitter:card" content="summary_large_image" />

And now I get the post to unfurl nicely.

This is the styling used by both Bing and Google. I put this in as a challenge to myself to make it work in both instances. I leaned a lot from the example on OrbitingWeb and refined what I was working with using another example that I found on github.

Valid Semantic Tags

For this, I just wanted to use some of those really cool semantic tags that html5 has given to us. When I look at the code for some pages on the internet I see a lot of <div> tags with classes that could be replaced with <main>, <nav>, or <section> tags.

I'm willing to just attribute it to my desire to have my own style or maybe just inexperience, but I'm happy to report that the site passes html validation except for the OpenGraph definitions found in the header.

figure it out

One technical hurdle I ran into was that I wanted my images to be wrapped in the <figure> tag and also have a <figcaption> tag that would have the alternative text.

I searched for a plugin for pelican2, but the closest thing I could find was liquid tags at the time3.

I did find jdittrich figureAltCaption project on github which was a extension for the python-markdown that pelican uses. I even submitted a pull request to allow it to do reference links!

There was a little confusion on getting it to work because pelican has been changing since some of these plugins were created.

Long story short, I had to add the following to my to get it to work.

   # Markdown Plugins
    'extension_configs': {
        'markdown.extensions.codehilite': {'css_class': 'highlight'},
        'markdown.extensions.extra': {},
        'markdown.extensions.meta': {},
    'output_format': 'html5',

Easy to share

I wrote down that I wanted the site to be easy to share and it is when you look at the amount of tags and metadata that is in every page.

At one point, I wanted to add share buttons, but -with the rise in concerns about privacy- I wanted the users of the site to be the ones who would share it.

Also, I'm still working on color schemes so the buttons might clash with whatever I end up with.

One of the underlining principles of this site design is that I wanted it to be accessible to as many people as possible. It's part of the reason that I've worked so hard on making sure that I included so many semantic tags. I didn't think that this was particularly hard to do when you understand what needs to happen before you begin.

The theme doesn't have any errors at this point, but does loose some points because of the way that markdown headers are handled and the fact that I picked a low contrast color for my links. I'll fix it soon.

Conclusion and where I'm going next

Overall, I'm happy with this version of the site and blogging about it has helped me think about what places I want to refine going forward.

List of things to improve

If you want to contribute you can find the theme on github here.

  1. Twitter is still my social network of choice and -despite it's flaws- is not as creepy as facebook. 

  2. Seriously didn't see Chris MacMackin's figure-ref until I was writing this article. I'll have to look into it for my next version. 

  3. I used this to make my previous theme Tufte and did not want to go down that road twice. It is very specific to pelican and I didn't want to dive into more regular expressions when I knew there had to be a solution already created.
