macro switch ((object &key test key) &body clauses) "Evaluates first matching clause, returning its values, or evaluates and returns the values of DEFAULT if no keys match." macro eswitch ((object &key test key) &body clauses) "Like SWITCH, but signals an error if no key matches." cswitch ((object &key test key) &body clauses) "Like SWITCH, but signals a continuable error if no key matches."

[alexandria-devel] darcs patch: Add #.#+ readtime conditional functions.

Mon Oct 16 10:00:31 CEST 2006 asf(a)boinkor.net * Add #.#+ readtime conditional functions. * This adds functions that can be used in #+#. readtime conditionals, for example: #+#.(alexandria:read-if (find-package :asdf-install)) :yay #+#.(alexandria:read-if-fbound :install :asdf-install :exportedp t) :yay * included in the patch is a commented-out portion that allows the user to activate a #? read syntax. I'm not sure if that fits into the conservativism constraints.

dear list, i've got this patch pending: (defmacro ensure-functionf (&rest places) "Call ENSURE-FUNCTION for each place in PLACES and store back the results." `(progn ,@(mapcar (lambda (place) `(setf ,place (ensure-function ,place))) places))) it might be controversial, so i'll first send it here. if noone complains for a week or two, then i'll push it eventually. -- attila
