Dear guix developers, Mathieu, Please find attached a first version of the cachefilesd service patch. The second patch for documentation will be sent right after. I have a few general newbie scheme questions: - I gathered that #~ / #$ kinds of suspends evaluation / forces it -- is there documentation about this somewhere ? - There's something that looks like a splat operator (only seen in conjuction with forcing evaluation in #$@) -- again i'd be interested in more documentation about this feature -- is this a guix-specific operator? - I don't understand why there are ^L separating services in the scheme files -- is this necessary? A convention? What purpose does it serve? Regarding the patch itself: - i'm not entirely sure the service belongs to services/linux.scm - documentation is hastily written. I have found no way to indent automatically the lisp code in the texi file, which is very painfull -- would there be an emacs solution for this? - there are no automated tests (beyond what I have done by hand locally!), and there's no lint, so I don't really feel confident about it :) Are there tests for services to alleviate my fears? - I've copied some other service for modprobing the required kernel modules before launching the daemon with a one-shot shepherd service. Frankly i'm not happy about this solution, it seems to me that it unnecessarily pollutes the shepherd configuration; maybe some other mechanism (graft?) adjusting the modprobe configuration could be better (better still, autoload the file). Any guidance would be nice (including, that this solution is sufficient for now :)) I had great fun writing this, it reminded me of writing cookbooks during my 'Chef' days. I must confess that the Chef DSL embedded in ruby seemed more concise, and that it provided a way to write a cookbook 'out-of-tree' which was kind of less daunting for newcomers; however it's already amazing that you have this kind of functionality! Kind regards, Jean-Baptiste
