Fwd: possible abcl bug: incorrectly deletes "unused" local function
by Erik Huelsmann 05 Apr '15

Hi Erik, ABCL appears to remove a function definition that it incorrectly thinks is unused. I've attached abcl-bug.lisp. Here is a transcript: ---- ABCL (fails) VibhuMondrasMBP:Desktop vibhu$ abcl.sh Armed Bear Common Lisp 1.3.1 Java 1.8.0_11 Oracle Corporation Java HotSpot(TM) 64-Bit Server VM Low-level initialization completed in 0.394 seconds.

[Armedbear-devel] Advancements in preparing ASDF system in ABCL for WAR
by Mark Evenson 06 Mar '15

06 Mar '15

A notice for those interested in my recent work in deploying ABCL as a WAR binary artifact of [an update to abcl-servlet][1], which is where I am collecting my ideas on implementation in an open source form. After locating the ASDF ABCL-SERVLET/BUILD definition, one may CL-USER> (abcl-servlet/prepare :hunchentoot) to create necessary packaging of Hunchentoot and its transitive ASDF dependences to [<file:hunchentoot/build/web/asdf/>][2] for merging into Java Servlet WAR archives. I’ve got a 100 Mib deployment WAR out of this system that has been running in production for six months now, but comments on how to generalise are welcome. [1]: https://bitbucket.org/easye/abcl-servlet/commits/e3bf36e015f2b5168d3e1d3d54… [2]: https://bitbucket.org/easye/abcl-servlet/src/b0e7e5353d6c92a1990ed1bb5500be… -- "A screaming comes across the sky. It has happened before but there is nothing to compare to it now." _______________________________________________ Armedbear-devel mailing list Armedbear-devel(a)common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/armedbear-devel

[Armedbear-devel] How to load compiled Lisp stuff from a jar
by Robert Dodier 06 Mar '15

06 Mar '15

Hi, I think maybe this topic has been covered before but I wonder what's the state of the art. I want to have a Java program load a compiled Lisp program contained in a jar so that I can then call functions in the Lisp code. For the record, the program in question is Maxima. Calling Lisp functions worked fine when the compiled code was unpacked (i.e. just in a directory) but I seem to recall it is not simply a matter of packing it into a jar. Or is it? Thanks for any advice. best, Robert Dodier PS. I apologize in advance for any gross misunderstanding on my part. _______________________________________________ Armedbear-devel mailing list Armedbear-devel(a)common-lisp.net http://mailman.common-lisp.net/cgi-bin/mailman/listinfo/armedbear-devel

[Armedbear-devel] Access to private methods from ABCL?
by Robert Goldman 06 Mar '15

06 Mar '15

Is there some way to find a private method and make it accessible, somewhat like the way JSS can make a private field accessible? Thanks! _______________________________________________ Armedbear-devel mailing list Armedbear-devel(a)common-lisp.net http://mailman.common-lisp.net/cgi-bin/mailman/listinfo/armedbear-devel

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?

[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
