I think so too. However, there are a few too many of these to start changing them over now. Or does anybody feel like hacking up a perl script to get it done? :-) Bye, Erik.

[armedbear-devel] abcl on AppEngine

Here's the first abcl "app" running on Google AppEngine: http://1.latest.abcl-test.appspot.com/hello . It's not much, but it's a start ;). -- All the best, Alex Muscar

[armedbear-devel] Using Java Libraries
by nitralime 19 Oct '09

19 Oct '09

Hi folks, I'm searching for a (more systematic) documentation (or tutorial) about how to use Java libraries from ABCL. I couldn't find anything else except the examples on "http://trac.common-lisp.net/armedbear/browser/trunk/abcl/examples/abcl". Is there any such tutorial (or documentation) at all? Any feedback is very much appreciated! Regards Nik

Hi, I've been messing around with the code.

[armedbear-devel] ABCL on Google App Engine (progress)
by Erik Huelsmann 19 Oct '09

19 Oct '09

Today, on IRC (irc://irc.freenode.net/#abcl), Alex and I have been working on getting ABCL to run on GAE (Google App Engine). We didn't complete our work, but since this mailing list has a wider audience than the IRC channel, I thought I'd forward our progress (his typing) to the mailing list. Possibly there are additional people interested. If others want to join in this effort to get ABCL running on GAE, I could commit the code to the examples directory in the repository. From there, we could make this a joint effort. One of the things we were running into is that we knew how to get a stream to the first-servlet.abcl file, but not how to get a path/URL to it. Can anybody contribute by answering how we should? When we know, we can do with the existing public functions, if there's not way, we need to make additional functions public. Bye, Erik. ---------- Forwarded message ---------- From: Alex Muscar <muscar(a)gmail.com> Date: Sun, Oct 18, 2009 at 6:13 PM Subject: The GAE bits To: ehuels(a)gmail.com Still hackish, though :(. We'll talk more about this tomorrow. -- All the best, Alex Muscar

[armedbear-devel] Serious bug involving UWP
by Tobias C. Rittweiler 18 Oct '09

18 Oct '09

Steps to reproduce: * ABCL from svn, updated a few minutes ago. * Slime from CVS. * M-x slime-scratch * Put (defun test (x) ,bar) in the buffer * Press C-c C-c You'll see "Evaluation aborted." in the minibuffer even though the debugger should have popped up complaining about comma not being inside backquote. C-c C-c is SWANK-COMPILE-STRING in swank-abcl.lisp. If you follow the control flow, you'll see that in SLDB-LOOP (we come here through *DEBUGGER-HOOK*) in swank.lisp, __the UNWINDED-PROTECT's protected form is *never* executed and it goes straight to the cleanup forms.__ -T.

[armedbear-devel] ABCL 0.16.1 released
by Erik Huelsmann 18 Oct '09

18 Oct '09

On behalf of the ABCL development team, I would like to announce the new ABCL release: 0.16.1 This release is a maintenance release on the 0.16 version line. In total four issues have been fixed: - In case of unsuccessful completion of a COMPILE call, ABCL would leak (= not correctly clean up behind itself) temporary files - In some cases, an exception thrown by a GO or RETURN-FROM form would not be correctly caught, causing the thread in which it occurs to terminate - Honor appearance of *&allow-other-keys* in CLOS MAKE-INSTANCE argument checking - More careful checking of 'null' arguments when processing stack frames Should you have any comments, remarks or bugs to be found in this release, please contact the developers through the mailing list mentioned on the ABCL project home page <http://common-lisp.net/project/armedbear/>.

[armedbear-devel] How to build the abcl.jar file within Eclipse
by dusan lukic 16 Oct '09

16 Oct '09

Hi all, I've downloaded ABCL from http://common-lisp.net/project/armedbear/ site, and, on it's building & running page, I've read that I can build abcl.jar file within Eclipse. I already have Eclipse installed on my computer, so can anyone, please, tell me how to do it. I do not have much experience with Eclipse, so a step-by-step procedure is preferred. Thanks, in advance.

Re: [armedbear-devel] [armedbear-cvs] r12180 - trunk/abcl/src/org/armedbear/lisp
by Erik Huelsmann 15 Oct '09

John, The commit below removes temporary file use from the COMPILE function. This is the minimal requirement to get running on GAE. So, I hope that you'll be using ABCL as of this version in your testing. I'm eager to learn about your progress. If you run into issues, please don't hesitate, we definitely want to fix them. If at all possible I'm for doing that ASAP. Bye, Erik.
