Guix provides an API, so you could use it from the comfort of the 'guix repl' REPL to query it, using fold-packages. The following repo will surely provide some clues as to how to do that; the following is an example querying all the packages that make use of the emacs-build-system [0] [0] https://notabug.org/apteryx/guix-api-examples/src/master/emacs-packages-manifest.scm Have fun! -- Thanks, Maxim
