[Armedbear-devel] Tail recursion
by Ralf Moeller 06 Mar '15

06 Mar '15

Hi all, ABCL does not seem to support tail call optimization right now. Are there any plans to provide this?

[Armedbear-devel] Having trouble with ASDF-JAR
by Robert Dodier 06 Mar '15

06 Mar '15

Hi, I'm trying ASDF-JAR again. I'm working with the svn trunk (current revision 14736). Here's what I get: CL-USER(1): (require 'asdf) ("uiop" "UIOP" "asdf" "ASDF") CL-USER(2): (require 'abcl-contrib) Using probed value of abcl-contrib: 'NIL'. ("ABCL-CONTRIB") CL-USER(3): (require 'asdf-jar) #<THREAD "interpreter" {13AD88B}>: Debugger invoked on condition of type SIMPLE-ERROR Don't know how to REQUIRE ASDF-JAR. I guess I'm doing something wrong? Thanks for your help, Robert Dodier _______________________________________________ Armedbear-devel mailing list Armedbear-devel(a)common-lisp.net http://mailman.common-lisp.net/cgi-bin/mailman/listinfo/armedbear-devel

[Armedbear-devel] Installing ABCL?
by Robert P. Goldman 06 Mar '15

06 Mar '15

Sorry if this is a stupid question, but is there a way to install ABCL in the standard sort of location (e.g., /usr/local/bin and /usr/local/lib, etc.)? I see that there's a copy of install-sh in the ABCL source, but I don't see a way to invoke it. I looked with find . \( -name '.git' -prune \) -o -type f -exec fgrep -q install-sh {} \; -print but didn't find anything. I have lots of bleeding edge lisp implementations because of needing to test ASDF, so was looking to figure out how to install using GNU stow for easy rebuilding and testing. [sorry if this is all handled by some Java thing like ant that I don't understand.] thanks, r _______________________________________________ Armedbear-devel mailing list Armedbear-devel(a)common-lisp.net http://mailman.common-lisp.net/cgi-bin/mailman/listinfo/armedbear-devel

[Armedbear-devel] ABCL and RMI
by Robert Goldman 06 Mar '15

06 Mar '15

I am trying to profile (using jvirtualvm) a program that I have compiled ABCL into. I'm using ABCL to script the application, and rapidly prototype extensions. The program is the PRISM model checker (http://www.prismmodelchecker.org/) for anyone who is interested. Oddly, I find that the profiler's call graph shows not just my top level main() program as a root, but also multiple jobs running RMI TCP connection. These are all in the idle state, but seem to be chewing up a lot of CPU. There are 16 of these processes and an RMI thread scheduler. Is there any way that ABCL could be causing this to happen? I don't see any use of RMI in the host PRISM program, but then I don't see it in ABCL, either. _______________________________________________ Armedbear-devel mailing list Armedbear-devel(a)common-lisp.net http://mailman.common-lisp.net/cgi-bin/mailman/listinfo/armedbear-devel

[Armedbear-devel] Strange behaviour of unexporting and defpackage
by Eitaro Fukamachi 06 Mar '15

06 Mar '15

Hi ABCL developers, I found a strange behaviour of cl-colors happening only on ABCL. [Issue] Symbols won't be exported on ABCL https://github.com/tpapp/cl-colors/issues/6 Though cl-colors unexports all symbols before defpackage when reloading the system, the :export clause in defpackage seems to be ignored. https://github.com/tpapp/cl-colors/blob/master/package.lisp#L5-L19 Any ideas?

[Armedbear-devel] How to get a fresh session or instance
by Robert Dodier 06 Mar '15

06 Mar '15

Hi, is there a way to get a fresh session or instance of ABCL, short of reloading all the classes? Ideally I'd like to be able to have two or more instances which exist at the same time and are independent of each other. I believe the answer to this question is "no", but I just want to make sure I am not overlooking something. If indeed it's not possible now, what would it take to make it happen? I see there is a certain amount of static data -- would it be necessary to replace that with (just for the sake of discussion) a hash table which takes a session or instance id as a key? Any thoughts on this topic will be appreciated. best, Robert Dodier _______________________________________________ Armedbear-devel mailing list Armedbear-devel(a)common-lisp.net http://mailman.common-lisp.net/cgi-bin/mailman/listinfo/armedbear-devel

Hi, Are there any GUI toolkits for the Bear? I am thinking in particular of something like Seesaw for Clojure.

[Armedbear-devel] EQUALP raises type-error comparing large bignums to floats (patch attached)
by Massimiliano Ghilardi 06 Mar '15

06 Mar '15

If a bignum exceeds the largest representable single-float, EQUALP will raise a type-error when comparing it to a single-float. The same problem happens with double-floats. I am reporting this because my understanding of CLHS http://www.lispworks.com/documentation/lw51/CLHS/Body/f_equalp.htm#equalp tells that EQUALP is not supposed to raise errors at all: "Exceptional Situations: None." How to reproduce: ;; =========== double-floats =========== (= (ash 1 1024) most-positive-double-float) NIL (equalp (ash 1 1024) most-positive-double-float) ; Evaluation aborted on #<TYPE-ERROR {215F90FE}>. ;; =========== single-floats =========== (= 340282360000000000000000000000000000000 0.0f0) NIL (equalp 340282360000000000000000000000000000000 0.0f0) ; Evaluation aborted on #<TYPE-ERROR {1CFFC364}>. In attachment the detailed stacktrace and a proposed patch to fix this problem.
