[alexandria-devel] Fwd: Knuth-Fisher-Yates shuffle
by Sean Ross 19 Dec '07

Hi all, I stumbled across this (http://www.codinghorror.com/blog/archives/001015.html) a little while ago and thought that alexandria's shuffle could do with an update. Please find the attached patch which updates the shuffle function. Cheers, Sean.

[alexandria-devel] starts-with and starts-with-subseq argument order
by Attila Lendvai 26 Nov '07

26 Nov '07

dear list, i've made a silly mistake and defined starts-with-subseq so that the order or the arguments is the opposite of starts-with: (defun starts-with (object sequence &key (test #'eql) (key #'identity)) (defun ends-with-subseq (sequence suffix &key (test #'eql)) i will correct this mistake if there's no objection, but this will break backward compatibility (there were no releases since the patch was added). please speak up if it's not desirable! -- attila

Type declareations like ((or fixnum null) bar) or (unsigned-byte foo) don't work on CLISP. Must use (type unsigned-byte foo) instead. Thu Jul 26 19:11:10 CEST 2007 Luis Oliveira <loliveira(a)common-lisp.net> * New macro: IGNORE-SOME-CONDITIONS Fri Jul 20 02:36:07 CEST 2007 Luis Oliveira <loliveira(a)common-lisp.net> * New macro: COERCEF Added respective documentation to the manual.

Why doesn't alexandria export SANS any more? Darcsweb points to: http://common-lisp.net/cgi-bin/darcsweb/darcsweb.cgi?r=alexandria-alexandri… regards, Samium Gromoff

[alexandria-devel] Proposed patches
by Luís Oliveira 23 Aug '07

23 Aug '07

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

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

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.
