Result folder appears empty

[behoppe]

Hi, I installed Nix, cloned this repo, and built the 'ctfp' edition. It looked like it was working, but then it seemed that my result was empty. Eventually I discovered a hidden file .pdf, and renamed that. Voila! That hidden .pdf was the book, which I am now reading.

Thank you.

Hi @drupol and thank you. Below is a transcript of my session, including user errors, which starts after I installed nix, logged out, and logged back in. (So the first command is where I discover that nix is finally working.) Now that I have the book PDF, I don't expect to need nix again, but I'm happy if this helps prevent others from having the same problem.
