This patch series add ‘remote-eval’, which takes a gexp, remotely deploys everything the gexp refers to, and evaluates it (see for the initial discussion.) So you can have gexps like: #~(execl #$(file-append ffmpeg "/bin/ffmpeg") …) When you evaluate it, this specific ‘ffmpeg’ will be deployed over there. Another example is: (with-imported-modules (source-module-closure '((gnu services herd))) #~(begin (use-modules (gnu services herd)) (map live-service-provision (current-services)))) This gexp, when evaluated remotely, will use your very own (gnu services herd) module and the corresponding Guile (so if you’re on Guile 3 and the remote is still on Guile 2, that’s fine: Guile 3 will first be deployed there.) ‘remote-eval’ allows you to build locally and send the build results, or to send the derivations and build remotely. The use case is for code that deals with state or has a side effect. Otherwise you’d just use a derivation and offload it. There are no tests for ‘remote-eval’ currently. It would need a VM with access to the store, as Jakob explained on guix-devel. Thoughts? Ludo’. Ludovic Courtès (4): gexp: Add 'lower-gexp' and express 'gexp->derivation' in terms of it. Add (guix repl). inferior: Add 'read-repl-response'. Add (guix remote).
