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:
|
||||
|
||||
@example
|
||||
$ guix package -p foo -i guile
|
||||
$ guix package -p bar -i guile-json
|
||||
$ guix package -p foo -p bar --search-paths
|
||||
@end example
|
||||
|
||||
The last command above reports about the @code{GUILE_LOAD_PATH}
|
||||
variable, even though, taken individually, neither @file{foo} nor
|
||||
@file{bar} would lead to that recommendation.
|
||||
|
||||
|
||||
@item --profile=@var{profile}
|
||||
@itemx -p @var{profile}
|
||||
Use @var{profile} instead of the user's default profile.
