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.

[alexandria-devel] switch
by Attila Lendvai 02 Aug '07

hi! i was touching SWITCH and friends to understand #'string= and 'string= and created a shared expander for the 3 variants. in the process i was thinking that removing the :default key arg and testing for a 'cl:otherwise clause would be much more cl-ish, but that would mean an incompatible change. (switch ("xxx" :test #'string=) ("alma" 1) ("korte" 2) (otherwise 42)) opposed to (switch ("xxx" :test #'string= :default 42) ("alma" 1) ("korte" 2)) what do people thing about it? -- attila

[alexandria-devel] HASH-TABLE-NEXT worthwhile to have?
by Samium Gromoff 10 Jul '07

Would it be worthwhile to have something like this: (defun hash-table-next (hash-table) "Returns the first EXIST-P, KEY, VALUE triple in the HASH-TABLE it can get its hands on; otherwise, NIL." (with-hash-table-iterator (fn hash-table) (fn))) ? regards, Samium Gromoff P.S. The original idea belongs to Tobias Rittweiler.
