Unable to quickload Drakma + CL+SSL on ABCL 1.3.2 - (Failed to read artifact descriptor for net.java.dev.jna:jna)
by Paul Nathan 27 Sep '15

Hello, I just downloaded ABCL 1.3.2 for OSX (curl -L -O http://abcl.org/releases/1.3.2/abcl-bin-1.3.2.tar.gz) and tried to load a few things in. Drakma & CL+SSL failed to load for me. I have copied the tracebacks to the end of the email. Please advise: is this my own error or something with ABCL? Is there more information you would like?

Better integration between ABCL & Java
by Blake McBride 30 Aug '15

30 Aug '15

Greetings, I worked hard on a project to link ABCL with a very large Java application. Although the addition of ABCL to that project failed, the work I did could be of use, and with some effort could be made to solve the problem I had. I believe the original problem I had would be a very common problem in similar circumstances. My pre-existing Java application has almost 10,000 classes! I wasn't about to create lisp cover functions for each java method. I also wasn't going to use a convoluted syntax to get to java each time. What I did was create some Java and Lisp code that, through reflection, caused the system to auto-generate a complete set of CLOS classes to mirror my primary java application classes - including the class hierarchy. The methods in these CLOS classes would call the Java methods. With this, when in Lisp, I could just use all of my Java classes and methods as regular CLOS classes and methods. It's use of Java classes and methods internally was transparent to lisp. All of this worked fine. The problem I ran into was the fact that Java can have several methods with the same name but different arguments. So, the Java method being called depended on the types and number of arguments too (not just the class of the instance and the method name). I never solved this, although I think it could be. I just ran out of time and steam, as well as other non-technical reasons. The reason I bring this all up now is because I am unclear about what problems Ralph is trying to solve. I thought what I have done may be of use. Thanks. Blake McBride

All conformance ansi-test's passed
by Ralph Ritoch 27 Aug '15

27 Aug '15

Hello, I have been able to get ABCL to pass all of the ansi conformance tests. While this is not an official ABCL release, all of the modifications I made are released under the MIT license and may be freely integrated into ABCL at the discretion of the maintainers. To embed this conforming version into your java applications add the following dependencies which have been released at maven central. <dependency> <groupId>com.vnetpublishing.lisp</groupId> <artifactId>jrelisp-abcl-impl</artifactId> <version>0.0.2</version> </dependency> <dependency> <groupId>com.vnetpublishing.lisp</groupId> <artifactId>jrelisp-abcl-contrib</artifactId> <version>0.0.2</version> </dependency> The source code for this release can be found at https://github.com/rritoch/jrelisp-abcl/tree/55e808d3c0084d16d1ed04c36a6f5a… . While I have moved some files around it is still an ABCL implementation that is mostly backwards-compatible with the official ABCL releases. Moving forward it is likely that any future development on these branches will further deviate from ABCL. I am not claiming that this solves EVERY compliance issue but I have found solutions for each of the ansi conformance test failures. Any remaining compliance issues can be considered a bug. My primary intention of passing every test is to lock the build process so that builds will fail if any of the ansi tests fail. It is unlikely that future modifications to these forks will have any relevance to ABCL. I will likely continue developing features that are needed for modern application development and therefore are of little interest to some, if not all, of the ABCL maintainers. That being said, v0.0.2 is the best release to source conformance solutions from for ABCL as it passes every conformance test. Any future releases will no longer be based on improving ABCL but be for the purpose of better supporting modern application development. Best Regards, Ralph Ritoch

loading lisp files from inside the java jar
by Hamda Binte Ajmal 18 Aug '15

18 Aug '15

Hi, I am sending this message again, as the last thread went a little too far. I have developed a Java Application that runs lisp code at the back end, and I use ABCL for that. Before using the lisp commands, I load a few .lisp files so that I can call the functions defined in those files. Everything works fine as long as I run the application from Netbeans. When I run the application from the jar file, it throws 'File not found error'. as the lisp files are not a part of file system inside the project jar. I tried to follow the suggestions given by Mark (load “jar:file:/absolute/path/to/file.jar!/path/within/jar/setup.lisp”) It shows the same File not found error. Am i missing something here? As suggested by Ralph to use (load-system-file "path/to/resource.lisp"), I tried to use that, but I was unable to access sys package, please let me know how to do this. I find the help documentation and tutorials very confusing, and difficult to understand. Any hints will be appreciated. Thanking in anticipation. Regards, Hamda NUIG, Ireland.

This "idiot" refactored a very small portion of your code making it MUCH faster, and also passed more than 90% of the tests ABCL is currently failing, leaving only 3 ansi-tests that are still failing. If I'm an idiot it doesn't say much about you since you've been working on this for years and I've only been working on it for weeks.

Lisp filepath issues when running application directly from jar file
by Hamda Binte Ajmal 17 Aug '15

17 Aug '15

Hi, I was working on an application, that loads a few lisp files using lisp command (load "fullfilepath.lisp") from java using ABCL. This file in turn loads the other lisp files located in same folder hierarchy, and then i call lisp functions (defined in these files) from java and everything works perfect as long as I run the application from Netbeans. Close to deployment, I tested the application by running it from jar file, I found that there are issues with filepaths, as the files are not a part of file-system, and hence not accessible using a file-path. Does anyone has any idea how to fix this issue ? I tried many things, like URL url = LispConnector.class.getResource("/Aima/aima/quicklisp/setup.lisp");String path = url.getFile();File f = new File(path); path = f.getAbsolutePath(); path = path.replace("\\", "/"); which returns [image: enter image description here] But which is wrong as this is not a valid file path and does not exists so lisp : (load "filepath") fails here. When I use the code String path = url.toURI();File = new File(path); path = path.getAbsolutePath(); Again it works fine while running from netbeans, but shows error "URI is not hierarchical" error while running the jar file. Has anyone encountered this issue, please help. -- Hamda Binte Ajmal NUIG, Ireland

Hello, Since you are loading resources and not from the filesystem you probably want to utilize the load-system-file function which I believe is provided by the :sys package. I'm not sure how portable this is so you may want to add some additional control logic if you want portability.

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
