ABCL on jailbroken iPhone
by Vibhu Mohindra 12 Aug '15

12 Aug '15

My jailbroken iPhone has GNU classpath[0] and jamvm[1] installed. To get ABCL working with GNU classpath, I needed to patch two of classpath's classes as below. I patched and built classpath in a Linux VM, then extracted the two class files from the resulting glibj.zip and inserted them into the iPhone's /usr/share/classpath/glibj.zip . I've reported these modifications to: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67188 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67189 the latter of which may be an ABCL problem, not a GNU classpath one.

Proposal to improve the loading of the abcl-contrib dependency.
by Ralph Ritoch 03 Aug '15

03 Aug '15

Hi, I have run into an issue with making executable abcl jars when the jar depends on, and provides, abcl-contrib. As far as I can tell abcl looks for abcl-contrib in the following locations. 1. Looks for a jar named abcl-contrib.jar in the classpath determined by probing the classloader for the jars it provides. 2. Looks in the directory of the jars in the classpath for a file named abcl-contrib.jar Neither of these solutions work if the currently executing jar includes abcl-contrib and isn't named abcl-contrib.jar. The following code proves that it is relatively easy to add this capability. (in-package 'sys) (sys:add-contrib (make-pathname :defaults (java:jcall "toString" (svref (java:jcall "getURLs" (sys:boot-classloader)) 0)))) This code properly loads abcl-contrib when the executing jar provides abcl-contrib, while (require 'abcl-contrib) does not. My proposal is to add a file named abcl-contrib/version.lisp to the abcl-contrib.jar, possibly in the /META-INF directory to avoid any potential conflicts with java, and to have sys:find-contrib look for this file in the resources provided by the classpath. The contents of this file is not important. This change makes it possible to include the abcl-contrib "dependency" directly inside the jar application that is currently running, regardless of the name of the jar file. Therefore, applications which make use of abcl-contrib can be distributed as a single jar. For maven users, this means that their uberjars will work by just including abcl and abcl-contrib as dependencies. For ant users they would probably need to extract abcl-contrib and include the extracted files in their generated jar which I believe can be fully automated. It would be relatively easy for me to produce a patch to provide this feature as part of ABCL. It may be possible to provide this feature as an add-on, but the functions needed within the system package are private (not exported) so it would be difficult, if not impossible, to implement this feature as an add-on. I would like your feedback on this issue. If this is a feature you want, or if you have any specific objections to including this feature in ABCL, please let me know. Best Regards, Ralph Ritoch

Build ABCL with Maven using these updated POM files.
by Ralph Ritoch 03 Aug '15

03 Aug '15

Hi, I have created some maven POM files which can be used to build and deploy ABCL with maven. There have been a few modifications to these over the past few days and there is probably room for improvement but these make it possible to build and depoy ABCL with the normal maven lifecycle. Included are the following pom.xml => abcl\pom.xml (abcl-parent) main-pom.xml => abcl\main\pom.xml (abcl) contrib-pom.xml => abcl\contrib\pom.xml (abcl-contrib) Note: Filenames are relative to the trunk so they include the abcl prefix. These have been posted as a gist on github at https://gist.github.com/rritoch/70f9f211c523499b794a I have tested by deploying to my localrepo and the abcl artifact is functional. Additional work may be needed on the abcl-contrib artifact POM because I'm unsure how to test it. The file size is similar to the one generated by ant so it may be correct. Best Regards, Ralph Ritoch

Are you looking for an idea for an ABCL project?
by Ralph Ritoch 01 Aug '15

01 Aug '15

Hi, I was invited by someone in the virt.x community to add ABCL to the virt.x project http://vertx.io/ . I don't foresee having the time to do the integration this year but if anyone is interested it looks like there are many in the Java development community who are interested in using common-lisp in their JVM applications. The virt.x system supports maven and integration with vert.x will most likely require that the maven integration issues, including integration of abcl-contrib from the classpath (maven) be resolved before integration will be possible. I don't currently use virt.x but it looks like a good system for large teams with diverse programming backgrounds. Best Regards, Ralph Ritoch

bug?
by Alejandro Zamora Fonseca 27 Jul '15

Hi! Just now playing a little with ABCL(1.3.2), I saw some strange behaviour: CL-USER> '(2 . 5) (2 . 5) CL-USER> '(2 . 5 . 5) (2 . 5) CL-USER> (equal '(2 . 5) '(2 . 5 . 5)) T while other implementations give me an error when i type '(2 . 5 . 5) it's a bug or ANSI CL allows this? greetings, Alejandro -- Este mensaje le ha llegado mediante el servicio de correo electronico que ofrece Infomed para respaldar el cumplimiento de las misiones del Sistema Nacional de Salud.

Bordeaux-threads issues
by Stelian Ionescu 22 Jul '15

22 Jul '15

Hi, can somebody take a look at the Bordeaux-threads support for ABCL? The test suite hangs on Travis-CI.org during automatic tests so I guess there's something wrong there. TraviCI runs Ubuntu 12.04 LTS on x86_64. Thanks. -- Stelian Ionescu a.k.a. fe[nl]ix Quidquid latine dictum sit, altum videtur.

Getting Java Class objects, and JSS
by John Pallister 08 Jul '15

08 Jul '15

Hello list, I'm working on getting ABCL + the Jetty <http://www.eclipse.org/jetty> web server + SLIME working together as a development environment for Google App Engine web apps[1]. This seems to be what the Clojure people have done <http://www.hackers-with-attitude.com/2009/08/intertactive-programming-with-…>: run your own Jetty server & SWANK server, then load the GAE JARs to provide the same emulated services as the GAE SDK's development server. I've been working through the "Embedding Jetty" tutorials[2] and making reasonable progress (with help from Mark Evenson and others on #abcl - thanks Mark!). I've been doing it all in Lisp (so far), making my own servlet classes using JNEW-RUNTIME-CLASS. Ideally I'd like to make an ABCL library equivalent to (a subset of) Compojure <https://github.com/weavejester/compojure> (and appengine-magic <https://github.com/gcv/appengine-magic>). Some of the tutorials have code like: context.addServlet(HelloServlet.class, "/"); Is it possible to get Class objects for Java classes I've made with JNEW-RUNTIME-CLASS (or indeed for any other Java class)? I've been using "raw" JCLASS & JMETHOD etc. calls to experience just how painful that really is, but I'm apprehensive about using JSS <http://abcl.org/trac/browser/trunk/abcl/contrib/jss/README.markdown> and paying the runtime dynamic dispatch penalty, given that on GAE time is money. Something more like a SLIME plug-in that looked up & cached classes, methods & fields at editing time (perhaps also parsing Java expressions) and generated "statically typed" code would be nice (possibly using code from e.g. JDEE <http://emacswiki.org/emacs/JavaDevelopmentEnvironment> and/or CEDET <http://cedet.sourceforge.net/>) - has anyone else thought about this? Cheers, John :^P (hoping HTML email to the list isn't a social faux pas) [1] I have a page of initial notes and links at https://johnp.net/jpkb/wiki/AbclOnGae [2] https://wiki.eclipse.org/Jetty/Tutorial/Embedding_Jetty, http://www.eclipse.org/jetty/documentation/current/embedding-jetty.html -- John Pallister john(a)johnp.net john(a)synchromesh.com

Licensing Issues
by Hamda Binte Ajmal 04 Jul '15

04 Jul '15

Hello, I am using ABCL to run lisp files in my Java code. ABCL is covered by the GNU General Public License with Classpath exception, meaning that you can use ABCL in your application without the requirement to open the sources to your application. So, I conclude the GNU GPL is not going to effect the license of my Java Code, BUT, what about the lisp code I load using ABCL? Would it have to be released under GNU GPL ? Regards, Hamda

Create Instance throws exception when Java Project located on network drive
by Hamda binte Ajmal 03 Jul '15

03 Jul '15

If the java project that is using ABCL is located on a network drive, Method Create isntance throws this exception: Exception in thread "AWT-EventQueue-0" java.lang.ClassCastException: org.armedbear.lisp.Nil cannot be cast to org.armedbear.lisp.Pathname at org.armedbear.lisp.Load.loadSystemFile(Load.java:329) at org.armedbear.lisp.Interpreter.initializeLisp(Interpreter.java:172) at org.armedbear.lisp.Interpreter.createInstance(Interpreter.java:72) ....... I believe this has something to do with the the path. (path \\fs2\14233205\NetBeansProjects\HamdaBinteAjmal-interface- 1ed1d2022f90 ) Please note that both the abcl.jar and the java project are located on a network drive. Anyway to resolve this? Regards, Hamda
