|
||
;;; Commentary:
|
||
|
||
;; Information about packages and generations is passed to the elisp
|
||
;; side in the form of alists of parameters (such as ‘name’ or
|
||
;; ‘version’) and their values. These alists are called "entries" in
|
||
;; this code. So to distinguish, just "package" in the name of a
|
||
;; function means a guile object ("package" record) while
|
||
;; "package entry" means alist of package parameters and values (see
|
||
;; ‘package-param-alist’).
|
||
;;
|
||
;; "Entry" is probably not the best name for such alists, because there
|
||
;; already exists "manifest-entry" which has nothing to do with the
|
||
;; "entry" described above. Do not be confused :)
|
||
|
||
;; ‘get-entries’ function is the “entry point” for the elisp side to get
|
||
;; information about packages and generations.
|
||
|
||
;; Since name/version pair is not necessarily unique, we use
|
||
;; `object-address' to identify a package (for ‘id’ parameter), if
|
||
;; possible. However for the obsolete packages (that can be found in
|
||
;; installed manifest but not in a package directory), ‘id’ parameter is
|
||
;; still "name-version" string. So ‘id’ package parameter in the code
|
||
;; below is either an object-address number or a full-name string.
|
||
;;
|
||
;; Important: as object addresses live only during guile session, elisp
|
||
;; part should take care about updating information after "Guix REPL" is
|
||
;; restarted (TODO!)
|
||
;;
|
||
;; ‘installed’ parameter of a package entry contains information about
|
||
;; installed outputs. It is a list of "installed entries" (see
|
||
;; ‘package-installed-param-alist’).
|
||
|
||
;; To speed-up the process of getting information, the following
|
||
;; auxiliary variables are used:
|
||
;;
|
||
;; - `%packages' - VHash of "package address"/"package" pairs.
|
||
;;
|
||
;; - `%package-table' - Hash table of
|
||
;; "name+version key"/"list of packages" pairs.
|
||
;;
|
||
;; - `%current-manifest-entries-table' - Hash table of
|
||
;; "name+version key"/"list of manifest entries" pairs. This variable
|
||
;; is set by `set-current-manifest-maybe!' when it is needed.
