I used this code sample when I rewrote my tool MakeMeFish into a cross-shell tool, MakeMe: https://github.com/OakNinja/MakeMe

I wrote a blog post about the conversion (GutHub pages, no tracking) here: https://blog.oak.ninja/development/2026/01/02/makeme-a-cross-shell-makefile-navigator.html

If you want to write a tool and use fzf as a lib, reach out / quote me and I'd be happy to help. fzf is extremely powerful and should be utilized by everyone and everything :)
