[alexandria-devel] darcs patch: Add #.#+ readtime conditional functions.
by asf＠boinkor.net 02 Oct '09

02 Oct '09

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, any objections agains this one? [Added simple-style-warning function and condition. attila.lendvai(a)gmail.com**20070827005343] { hunk ./errors.lisp 9 +(define-condition simple-style-warning (style-warning simple-warning) + ()) + +(defun simple-style-warning (message &rest args) + (warn 'simple-style-warning :format-control message :format-arguments args)) + + hunk ./package.lisp 117 + #:simple-style-warning } maybe errors.lisp should be renamed to conditions.lisp? -- attila

[alexandria-devel] Proposed patches

Hello, I would like to propose the following patches for inclusion in Alexandria: Wed Jul 11 15:03:50 WEST 2007 Luis Oliveira <loliveira(a)common-lisp.net> * Remove trailing whitespace in source code Fri Jul 20 01:34:20 WEST 2007 Luis Oliveira <loliveira(a)common-lisp.net> * New function: FEATUREP Added respective documentation in manual as well. Fri Jul 20 01:35:23 WEST 2007 Luis Oliveira <loliveira(a)common-lisp.net> * New macro: NCONCF - Added respective documentation to the manual. - New test: NCONCF.1 Fri Jul 20 01:36:07 WEST 2007 Luis Oliveira <loliveira(a)common-lisp.net> * New macro: COERCEF Added respective documentation to the manual. Thu Jul 26 18:11:10 WEST 2007 Luis Oliveira <loliveira(a)common-lisp.net> * New macro: IGNORE-SOME-CONDITIONS Mon Aug 6 17:02:06 WEST 2007 Stelian Ionescu <sionescu(a)common-lisp.net> * Fix some type declarations for CLISP-compatibility. Type declareations like ((or fixnum null) bar) or (unsigned-byte foo) don't work on CLISP. Must use (type unsigned-byte foo) instead. Thu Aug 23 05:05:00 WEST 2007 Luis Oliveira <loliveira(a)common-lisp.net> * Small fix to REQUIRED-ARGUMENT's control string. Thu Aug 23 05:05:56 WEST 2007 Luis Oliveira <loliveira(a)common-lisp.net> * Simplify IGNORE-SOME-CONDITIONS's docstring. These can be pulled via: darcs pull http://common-lisp.net/~loliveira/darcs/alexandria I also think it'd be useful to add something similar to SB-KERNEL:WITH-ARRAY-DATA. While this can be done portably for displaced unidimensional arrays, I'm not aware of a way to do it portably for multidimensional arrays or adjustable arrays without copying. Is there some policy against implementation-specific code? Thanks, -- Luís Oliveira http://student.dei.uc.pt/~lmoliv/

[alexandria-devel] sans-bind, or programmatic sharing of keyword arguments
by Samium Gromoff 06 Aug '07

06 Aug '07

I've finally catched a recurrent thought in a material-enough state, so i can get together enough mental energy to expand on it. Suppose there are two functions (or macros), %A and A, and, as the notation implies, %A is the lower-level implementing one. Suppose that A is supposed to accept as-is a large part of the keyword arguments %A accepts, and perhaps, accept several of its own, possibly defaulting them to some values. A straightforward implementation would be to accept the same keyword arguments and then re-feed them literally, one by one, to %A. That has obvious disadvantages, though. So, what A could do, is to get &rest arglist, and process it programmatically, by: - filtering out A-specific key-value pairs - binding them (and possibly defaulting) - yielding the A-specificity-free plist ready to be fed to APPLY #'%A (or to ,@), which is doable by ALEXANDRIA:SANS What do you think, folks? regards, Samium Gromoff

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

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
