rippkgs-index provides no output feedback to user during indexing

[montchr]

When I run rippkgs-index as instructed in the README, I expect to see some kind of confirmation that anything at all is happening.

Currently, the program runs but appears to hang indefinitely because it echoes no output messages.

Until I ran htop and saw high resource usage from the Nix daemon and from the nix eval process, I wasn't sure whether rippkgs-index was working or whether I made some mistake.

Example

Note that I have my NixOS configuration's flake inputs symlinked to /etc/nix/inputs/. I do not think that is related to the issue, however, because I also encountered the same behavior when using inputs.nixpkgs.outPath in a custom script.

rippkgs-index nixpkgs -o $XDG_DATA_HOME/rippkgs-index.sqlite /etc/nix/inputs/nixpkgs
