||
;;; 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.
|
||
|
||
;; ‘entries’ procedure 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.
|
||
|
||
;; 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.
