Pelican is the static site generator that I use for my website. This allows me to write my website posts in almost plain text (actually a light-weight markup language named reStructuredText), which are then translated into HTML. As someone who has written his webpages in HTML by hand, I can tell you that this is definitely an improvement.
Although I use LaTeX for things that require high-quality typesetting, these days almost all my other writings are in reStructuredText.
The previous pelican version 3.7 was basically the last Python 2.7 application that I use. So now that pelican supports Python 3, I’m switching. Since Pelican 4 is not in the FreeBSD ports tree yet, I’m installing it myself.
