civodul pushed a commit to branch master
in repository guix.
commit fc2d2339644b408574f0ead4436e751fa423a7e6
Author: Ludovic Courtès <address@hidden>
Date: Tue Nov 10 22:00:53 2015 +0100
guix package: '--search-paths' can report combined search paths.
Partly fixes <http://bugs.gnu.org/20255>.
* guix/scripts/package.scm (search-path-environment-variables): Change
'profile' to 'profiles'; expect it to be a list.
(display-search-paths): Likewise.
(%default-options): Remove 'profile' entry.
(%options) <--profile>: Keep previous values associated with 'profile'
in RESULT.
(guix-package)[process-actions, process-query]: Handle the possible
lack of 'profile' pair in OPTS.

@@ -1347,6 +1347,20 @@ meaning that the returned environment variable
definitions will either
be exact settings, or prefixes or suffixes of the current value of these
variables. When omitted, @var{kind} defaults to @code{exact}.
+This option can also be used to compute the @emph{combined} search paths
+of several profiles. Consider this example:
+
address@hidden
+$ guix package -p foo -i guile
+$ guix package -p bar -i guile-json
+$ guix package -p foo -p bar --search-paths
address@hidden example
+
+The last command above reports about the @code{GUILE_LOAD_PATH}
+variable, even though, taken individually, neither @file{foo} nor
address@hidden would lead to that recommendation.
+
+
@item address@hidden
@itemx -p @var{profile}
Use @var{profile} instead of the user's default profile.
