[armedbear-devel] Calling java from lisp
by Arnaud Bailly 06 Apr '12

06 Apr '12

Hello (again), I am trying to invoke java code from lisp code following http://common-lisp.net/project/armedbear/doc/abcl-user.html. Here is the code I am trying to run: CL-USER> (defun java-format (fmtstring &rest args) (let* ((string-class (jclass "java.lang.String")) (array-of-objs (jclass "[Ljava.lang.Object;")) (method (jmethod string-class "format" string-class array-of-objs))) (jcall method fmtstring args))) JAVA-FORMAT And here is what I got when I try to run it: > (java-format "" "%d %08.d %s" 1 2 3) Wrong number of arguments for public static java.lang.String java.lang.String.format(java.lang.String,java.lang.Object[]): expected 2, got 1 [Condition of type PROGRAM-ERROR] Restarts: 0: [RETRY] Retry SLIME REPL evaluation request. 1: [*ABORT] Return to SLIME's top level. 2: [ABORT] Abort thread. Backtrace: 0: (#<FUNCTION {53C470B}> #<PROGRAM-ERROR {76F2D004}> #<FUNCTION {53C470B}>) 1: (APPLY #<FUNCTION {53C470B}> (#<PROGRAM-ERROR {76F2D004}> #<FUNCTION {53C470B}>)) 2: (SYSTEM::RUN-HOOK SYSTEM::*INVOKE-DEBUGGER-HOOK* #<PROGRAM-ERROR {76F2D004}> #<FUNCTION {53C470B}>) 3: (INVOKE-DEBUGGER #<PROGRAM-ERROR {76F2D004}>) 4: org.armedbear.lisp.Lisp.error(Lisp.java:381) 5: org.armedbear.lisp.Java.jcall(Java.java:880) 6: org.armedbear.lisp.Java$pf_jcall.execute(Java.java:755) 7: org.armedbear.lisp.Primitive.execute(Primitive.java:135) 8: (JCALL #<java.lang.reflect.Method public static java.lang.String j.... {451CF2D}> "" ("%d %08.d %s" 1 2 3)) 9: (JAVA-FORMAT "" "%d %08.d %s" 1 2 3) 10: (SYSTEM::%EVAL (JAVA-FORMAT "" "%d %08.d %s" 1 2 3)) 11: (EVAL (JAVA-FORMAT "" "%d %08.d %s" 1 2 3)) --more-- What am I doing wrong ?

But I see your point about API changes, especially for a non-major release. I guess right now we're bike-shedding. Let's hear what Pascal prefers, but I'm leaning towards your version as well at the moment. I'm not hell-bent on it, just wanted to point that out since I did consider that even though my patch doesn't mention such considerations. Ville-code is sometimes like that, it's well thought-out and minimal, modify anything and things break (for certain values of "break"), but I'm not the best user of explanatory comments on the planet. :)

[armedbear-devel] run-program :environment nil
by Pascal J. Bourguignon 28 Mar '12

28 Mar '12

(lisp-implementation-version) --> "1.0.1" The documentation of extensions:run-program is misleading: :environment An alist of STRINGs (name . value) describing the new environment. The default is to copy the environment of the current process. The alist doesn't describe the NEW environment, it is only MERGED into the current environment. Now of course, I consider the current behavior to be a bug: (text-stream-contents (extensions:process-output (extensions:run-program "env" '() :wait t :environment 'nil))) --> ("NNTPSERVER=news.individual.net" "ESHELL=/bin/bash" …) I would expect: (text-stream-contents (extensions:process-output (extensions:run-program "env" '() :wait t :environment 'nil))) --> () and: (text-stream-contents (extensions:process-output (extensions:run-program "env" '() :wait t :environment '(("LC_CTYPE" . "C"))))) --> ("LC_CTYPE=C")) Which would match what the documentation says. Also, in a shell environment, an empty variable is not the same as an inexistant variable, so I cannot just loop over all the existing variables to set them to an empty string. I see no SYSTEM::%PROCESS-BUILDER-ENV-REM function… -- __Pascal Bourguignon__ http://www.informatimago.com/ A bad day in () is better than a good day in {}.

[armedbear-devel] ABCL on jdk-1.7.0_03
by Mark Evenson 21 Mar '12

21 Mar '12

I've just run abcl-1.1.0-dev the ANSI-COMPILED tests on jdk-1.7.0_03 with reasonable looking results of 31 failures, which is roughly the same number as those run with jdk-1.6.0_31 (some of the tests use randomly generated data so they sometimes either fail or succeed). Previously, I think that we weren't even completing the ANSI-COMPILED test suite due to issues in the character set encoding, so I think we should now more fully endorse running ABCL on Java7.

[armedbear-devel] compiling lisp files outside Java and calling it after with abcl
by scarbonell＠ono.com 02 Mar '12

02 Mar '12

Hi,I'm trying to compile a lisp application and I get a lot of errors with java abcl. I thought that if I try to compile this lisp files outside of abcl with other systems, perhaps, I could then call this compiled functions lisp files from ABCL (look like a jar file of lisp compiled files). Is this possible?How can I compiled this files outside ABCL? Some examples?Thanks

[armedbear-devel] Upcoming abcl-1.1 branch
by Mark Evenson 25 Feb '12

25 Feb '12

On [#abcl]() yesterday, ehu and easye discussed how it would be a good idea to start packing up for shipping abcl-1.1 out the door. [#abcl]: http://webchat.freenode.net/?randomnick=1&channels=abcl&prompt=1&uio=d4 Out of our brief discussion, we'd like to branch the trunk in about a week, stabilize with testing, and then release abcl-1.1.0 on 14-FEB-2012. So, unless there are objections, we'd like to start by asking everyone who was thinking of patching something, to think about getting some time in the next week to get something done. All potential contributions are welcome. If you were going to document something, now's the time! [Rudi added real BibTex-based markup to the Manual][1], so even something as trivial as fixing the references would be appreciated. [1]: http://code.google.com/p/abcl-dynamic-install/source/detail?r=5c7faeeb35408… yers in CONS, Mark -- "A screaming comes across the sky. It has happened before, but there is nothing to compare to it now."

[armedbear-devel] Patch for ABCL to dynamically load CFFI JNA requirement
by Mark Evenson 24 Feb '12

24 Feb '12

Please consider the referenced patch for inclusion in cffi-0.10.7. Comments towards improvments solicited. Improvements to ABCL CFFI implementation: o autoload the 'jna.jar' dependency if possible (requires abcl-1.1.0-dev) o initial implementation of callbacks Needs ABCL specific tests, but I can load CL+SSL with this patch. [1]: http://slack.net/~evenson/abcl/cffi/abcl-cffi-20120224a.diff Cheers, easyE -- "A screaming comes across the sky. It has happened before, but there is nothing to compare to it now."
