pcache provides a persistent way of caching data, in a hashtable-like structure. It relies on `eieio-persistent' in the backend, so that any object that can be serialized by EIEIO can be stored with pcache.
pcache handles objects called "repositories" (pcache-repository) and "entries" (pcache-entry). Each repository is identified by a unique name, that defines an entry in pcache-directory. Subdirectories are allowed, by the use of a directory separator in the repository name.
Example:
(let ((repo (pcache-repository "plop"))) (pcache-put repo 'foo 42) ; store value 42 with key 'foo (pcache-get repo 'foo) ; => 42 )
Keys can be pretty much any Lisp object, and are compared for equality using eql
Optionally, cache entries can expire:
(let ((repo (pcache-repository "plop"))) (pcache-put repo 'foo 42 1) ; store value 42 with key 'foo for 1 second (sleep-for 1) (pcache-get repo 'foo) ; => nil )
