[alexandria-devel] Alexandria/SBCL buglet
by Daniel Herring 02 Nov '08

02 Nov '08

There's a subtle bug in the 'include' target in alexandria/doc/Makefile. include: sbcl --eval '(progn (require :asdf) (require :alexandria) (rename-package :alexandria :alexandria))' \ --eval '(load (merge-pathnames "doc/manual/docstrings" (posix-getenv "SBCL_SOURCE_ROOT")))' \ --eval '(sb-texinfo:generate-includes "include/" :alexandria)' \ --eval '(quit)' mv include/fun-alexandria-type=.texinfo include/fun-alexandria-type-equal.texinfo When the SBCL manual is built, it creates a directory named "docstrings"; so you now have both doc/manual/docstrings and doc/manual/docstrings.lisp Thus (load (merge-pathnames "doc/manual/docstrings" ...) fails with a debugger invoked on a SB-INT:SIMPLE-STREAM-ERROR in thread #<THREAD "initial thread" RUNNING {100274FC21}>: couldn't read from #<SB-SYS:FD-STREAM for "file /path/to/sbcl/doc/manual/docstrings" {1002871401}>: Is a directory [SBCL 1.0.22.7 on x86-64 linux] - Daniel P.S. Since "clean:" is the first target in this Makefile, it runs by default when you simply type `make`. That surprised me; I expected the first rule to be something like all: pdf html or all: echo "Try 'make clean', 'make pdf', or 'make html'."

I'm inclined to agree: (PROG1-LET (X (FOO)) (BAR X) (QUUX X)) is easily taken to mean (LET ((X (FOO))) (PROG1 (BAR X) (QUUX X))) (Well, I'm not sure about abuse part, but readability seems to suffer.)

[alexandria-devel] PROG1-LET
by Volkan YAZICI 27 Oct '08

27 Oct '08

Hi, Do alexandria developers consider including PROG1-LET? (I find it quite useful, and it is included in the very early lines of nearly every of my utils.lisp files.) (defmacro prog1-let ((var val) &body body) `(let ((,var ,val)) ,@body ,var)) Regards.

[alexandria-devel] Testing with Lisps other than SBCL, patches
by Luis Oliveira 21 Aug '08

21 Aug '08

Hello, Yesterday I decided to test Alexandria with a couple of Lisps. The following patches resulted from that session, except MULTIPLE-VALUE-PROG2 whose usefulness is admittedly debatable. Sun Jul 27 04:01:39 WEST 2008 Luis Oliveira <loliveira(a)common-lisp.net> * Mark expected failures for Allegro CL: TYPE=.[234] Sun Jul 27 04:01:30 WEST 2008 Luis Oliveira <loliveira(a)common-lisp.net> * amend COPY-SEQUENCE.1 - can't assume that (upgraded-array-element-type 'fixnum) => fixnum. Fix that. Sun Jul 27 03:54:27 WEST 2008 Luis Oliveira <loliveira(a)common-lisp.net> * tests: mark CLISP failures - COPY-HASH-TABLE.1 causes a stack overflow due to a CLISP bug. - ALIST-HASH-TABLE.1, PLIST-HASH-TABLE.1 fail because HASH-TABLE-TEST returns EXT:FASTHASH-{EQ,EQL}. Sun Jul 27 03:46:35 WEST 2008 Luis Oliveira <loliveira(a)common-lisp.net> * tests: define and use ERRORP - TYPEP returns a generalized boolean. On Lisps like ECL, this detail was causing some tests to fail. ERRORP takes this into account. Sun Jul 27 03:45:07 WEST 2008 Luis Oliveira <loliveira(a)common-lisp.net> * Small fix to COPY-HASH-TABLE - New hash-table was being created with a bogus rehash-size. - Added regression test in another patch. Sun Jul 27 03:43:21 WEST 2008 Luis Oliveira <loliveira(a)common-lisp.net> * Define an alexandria-tests ASDF system. - make it usable for other Lisps besides SBCL. - TEST-OP runs tests both compiled and evaluated. Sun Jul 27 03:37:13 WEST 2008 Luis Oliveira <loliveira(a)common-lisp.net> * New macro: MULTIPLE-VALUE-PROG2 These patches can be pulled via darcs pull http://common-lisp.net/~loliveira/darcs/alexandria -- Luís Oliveira http://student.dei.uc.pt/~lmoliv/

[alexandria-devel] WITH-STRUCT
by Tobias C. Rittweiler 17 Aug '08

17 Aug '08

WITH-STRUCT is the WITH-SLOTS pendant for structures. I think there are different syntactic variants out there. I'm used to the one in SWANK which looks as follows: (defstruct (foo-struct (:conc-name foo-struct.)) slot1 slot2 slot3) (with-struct (foo-struct. slot1 slot2 slot3) *foo-struct* ...) -T.
