merge-pathnames bug with :back component
by Vibhu Mohindra 14 Jun '16

14 Jun '16

CLHS for merge-pathnames specifies that, "This removal of redundant :back keywords is repeated as many times as possible." abcl-1.3.2 The first expression below evaluates correctly, but the second produces an error. FCFS(34): (merge-pathnames (make-pathname :directory '(:relative "a" "b" :back)) (make-pathname :directory '(:absolute "root"))) #P"/root/a/" FCFS(35): (merge-pathnames (make-pathname :directory '(:relative "a" "b" :back :back)) (make-pathname :directory '(:absolute "root"))) #<THREAD "interpreter" {43B4AF3C}>: Debugger invoked on condition of type FILE-ERROR Unsupported directory component BACK. Restarts: 0: TOP-LEVEL Return to top level. For what it's worth, CCL also produces an error. CLISP, ECL, SBCL correctly produce: #P"/root/" (That said, I'm far from a pathname expert and could be completely wrong.) Vibhu

publish system::expand-deftype ?
by Massimiliano Ghilardi 12 Jun '16

12 Jun '16

Hello, for my library https://github.com/cosmos72/cl-parametric-types I need the function introspect-environment:typexpand, which expands DEFTYPE'd types, similarly to what CL:MACROEXPAND does for macros. Even though introspect-environment does not support ABCL, I found that system::expand-deftype does exactly what I need, yet I am wary of using a non-exported symbol from ABCL. Is system::expand-deftype stable enough to be published as an ABCL extension to ANSI CL and to be used to implement introspect-environment:typexpand ? Regards, Massimiliano

function documentation patch

When a function object is given to describe function documentation is not shown (it's shown on the symbol). Because of this, the slime function documentation doesn't show it either.

Format ~$ buglet
by Scott L. Burson 28 Apr '16

28 Apr '16

In 1.3.2, > (format nil "~$" -32.17) --32.17 Negative values are getting a double minus sign. The right fix seems to be, in 'format-dollars', to pass '(abs number)' rather than 'number' to 'sys::flonum-to-string'. -- Scott

ASDF 3.1.7 has been released
by Robert P. Goldman 23 Mar '16

23 Mar '16

ASDF 3.1.7 is a bugfix release, enhancing the 3.1.x ASDF series. To the best of our knowledge, it only fixes bugs, and should thus be a low-risk upgrade for inclusion in implementations. Thanks, as ever, to Faré for many fixes, and to other bug reporters and patch-suppliers. See the Changelog (below) for a summary of changes. Bug fix and portability release: * Fix compilation on Genera. * Fix UIOP:FILE-EXISTS-P for dotfiles on CCL. * Fix infinite loop in source registry configuration that can occur when there are cycles in the filesystem (typically caused by symlinks) on some CL implementations. * Miscellaneous bug fixes. * Documentation improvements. * Restore original Makefile. -- Robert P. Goldman <rpgoldman(a)sift.net> Wed, 23 Mar 2016 09:34:14 -0500

Syntactic sugar to call Java from ABCL?
by EGarrulo 06 Mar '16

06 Mar '16

Hello ABCL developers, has anybody written some macros to make calling Java from ABCL more straightforward? I mean something that, instead of this code from the ABCL documentation: (defun void-function (param) (let* ((class (jclass "Main")) (intclass (jclass "int")) (method (jmethod class "addTwoNumbers" intclass intclass)) (result (jcall method param 2 4))) (format t "in void-function, result of calling addTwoNumbers(2, 4): ~a~%" result))) would let you write something like this, for example: (format t "in void-function, result of calling addTwoNumbers(2, 4): ~a~%" ;; Let's imagine that we have defined a -> macro. (-> |Main.addTwoNumbers| 2 4) Thank you.

Debugging ANSI tests
by Alessio Stalla 07 Feb '16

07 Feb '16

Hi list, in my local copy of ABCL I broke some ANSI tests related to packages and that's not good. I'm lazy so I'm asking here: does someone have a ready recipe to debug the ANSI tests, in particular to place breakpoints inside ABCL's Java code while it is executing the tests? In the minute or so I spent thinking about it before getting lazy, I couldn't figure out how to pass the jdwp incantation to the JVM launched by Ant when testing. Thanks is advance! Alessio
