Does anyone even use prolog?

It's not very common, but I feel like prolog doesn't get the credit it deserves. It takes some getting used to, but once you do get the hang of it, it's amazingly powerful.
I worked on a log parser that parsed 10,000 lines per second, backtracked through the logs to verify information or gather further data only when needed without having to cache anything. In any other programming language it would have been a nightmare.
A second project I did: I used DCG to write a "thought/musing organiser" in just 80 lines of code. I used that as the back end for an app.
You can find some pretty creative uses for it. Give it a chance.

It was a legitimate question hahahah, not trying to be sassy

Guess I sounded a bit too preachy myself :)
To answer your question: Rarely
Personally, I wish it was used more widely, but that's just me (probably actually is just me)

P.s: the comment above was my first ever comment on devrant :) and in defence of prolog... Who'da thunk it?

I was asking myself that too, but I guess it has its uses

chances are that your uni does
