guix size with manifest?

[Spencer Skylar Chan]

Dear Guix,

How do I run guix size with a manifest? Most guix shell commands use -m 
for a manifest file, but guix size uses -m for map-file. Right now I'm using

grep -F \" manifest.scm | cut -d \" -f 2 | xargs guix size

but this would only work for autogenerated manifests from
guix shell --export-manifest and not manifests written by hand.

Thanks,
Skylar

I am interested to hear other ideas, but if you install the manifest
into a profile you can then size the list of packages from the profile
(which should be equivalent to the obtaining the full listing from
shell's export-manifest):

$ guix package --profile=profile --list-installed \
  | cut --fields=4 \
  | xargs guix size \
  | less --quit-if-one-screen

I hope you will not regret this sentence once you see my "one-liner":

$ cat manifest.scm
;; What follows is a "manifest" equivalent to the command line you gave.
;; You can store it in a file that you may then pass to any 'guix' command
;; that accepts a '--manifest' (or '-m') option.

(specifications->manifest (list "gcc-toolchain"))
$ printf '(use-modules (guix packages) (guix derivations) (guix store) (guix profiles) (guix scripts environment) (guix scripts size)) ((@@ (guix scripts size) display-profile) (run-with-store (open-connection) ((@@ (guix scripts size) store-profile) (map (λ (entry) (derivation->output-path (run-with-store (open-connection) (package->derivation (manifest-entry-item entry))))) (manifest-entries (load-manifest "manifest.scm"))))))' | guix repl /dev/stdin

The code is based on the "hack at it until it works" approach, not on the "ok so
I should first try to understand store monads" approach, so I am sure there are
issues with it.  But on my simple example it seems to work.  The path
("manifest.scm") is hard-coded though.
