Looking at my manifest file I see that, e.g., the entry for
'python-matplotlib' lists all recursively propagated
dependencies. Differently from this the 'search-paths' entry only lists
the entries defined in the package (in this case none), neglecting the
search paths in the 'propagated-inputs'.
If I understand correctly, this behavior is defined by this function (from
guix/profiles.scm):
(define* (package->manifest-entry package #:optional output)
"Return a manifest entry for the OUTPUT of package PACKAGE. When OUTPUT is
omitted or #f, use the first output of PACKAGE."
(let ((deps (map (match-lambda
((label package)
(gexp-input package))
((label package output)
(gexp-input package output)))
(package-transitive-propagated-inputs package))))
(manifest-entry
(name (package-name package))
(version (package-version package))
(output (or output (car (package-outputs package))))
(item package)
(dependencies (delete-duplicates deps))
(search-paths (package-native-search-paths package)))))
To get all the required search paths recursively we should replace the
last 'manifest-entry' slot with a call to a function like this:
(define (collect-package-search-paths package)
(define (collect-search-paths package)
(let ((propagated-inputs (package-propagated-inputs package))
(search-paths (package-native-search-paths package)))
(append search-paths
(append-map
(match-lambda
((name pkg . rest) (collect-search-paths pkg))
(_ '()))
propagated-inputs))))
(delete-duplicates (collect-search-paths package)))
Or, am I missing how this works?
