Hi, I found a procedure like this (then at the top of my system
config.scm's) to be quite useful:

diff --git a/gnu/packages.scm b/gnu/packages.scm
index fb27738..63500ab 100644
- --- a/gnu/packages.scm
+++ b/gnu/packages.scm
@@ -228,6 +228,14 @@ decreasing version order."
                     matching)
             matching)))))

+(define (find-guix-packages list-of-names)
+  (map
+   car
+   (map
+    find-packages-by-name
+    list-of-names)))
+
+
 (define find-newest-available-packages
   (memoize
    (lambda ()


Which could be used in the config like this (for example):

;; Globally-installed packages.
  (packages
   (append
    (find-guix-packages
     '("htop"
       "wget"
       "xmonad"
       "openssh"
       "dmenu"
       "git"
       "xterm"
       "emacs"))
    %base-packages))

and which saves the user from manually entering the use-modules for
the module packages at the top of the config.

I am aware that is maybe still too simplistic. E.g.: It might be good
to check if the name is ambiguous instead of just taking the first
result and throw an error in that case.

As a typical programmer I am allergic to seemingly redundant and
automatable tasks, so I'd love to see something at least similar in
spirit in guix.

Thoughts?

Regards,
Flo
