I write this blog using a combination of
make and a small-ish python script called bari.
It is easy for me to design, write and maintain my own code than inherit someone else’s assumptions and “wants” for their software.
I saw another blog https://blog.notryan.com/ that is also written in a similar spirit – uses only C, and a bash script to generate a “text only” blog and RSS feed.
So, go on, write your own little program(s) to do what you need to get writing. Some of it is yak-shaving; but some yaks are small, some of you are expert shavers. You will figure it out.
