Any potential users still in the market for a static site generator are as spoilt for choice as they're ever likely to get, and people seem to be picking the engine with the most stars that's written in their language of choice. That's a happy enough feedback mechanism for what are mostly good pieces of work, but one that means any adventurous souls with the desire to roll their own new engines will have very little incentive to publish. Frankly there's probably little enough need for them to, whatever innovation there was to be had in what is after all a reasonably straightforward problem domain seems to have been tapped out a while back.
Writing a static blog engine is still an interesting enough side project, it became my go to test when kicking the tyres on any new programming language, and there are certainly plenty of existing examples to learn from, but as the Twitter joke would have it:
Beautiful is better than ugly. Readability counts. Python's grown on me. I turned down a job once years ago because it mostly consisted of writing Python code (also the pay was lousy) but life is full of little ironies. This might be a thing now, this Python thing.
Swift and Python are a nice match. More on that later probably, but for now, speaking of what must surely be well trodden ground, the code used to generate that graph, with something like a first stab at a wrapper function for some matplotlib functions…
Update 15 September 2018: I removed the embedded gist that was here, the gist of course is still available.
