Applied to SLIME CVS HEAD. Thanks for the patch! I tested with abcl-0.{15,16} and HEAD with the patch working as I expected. Keeping compatibility with more ancient versions of ABCL takes a too much of my scant resources, but if someone is stuck with a previous version of ABCL they wish to maintain compatibility with SLIME CVS HEAD, drop me an email to work something out. For those following the "old" armedbear-j-devel(a)lists.sourceforge.net list, and perhaps wondering why things have been so quiet lately, note that we moved [ABCL specific traffic to common-lisp.net][1] some months ago.

[armedbear-devel] [ANN] Snow 0.1 released - GUI library for ABCL
by Alessio Stalla 15 Sep '09

15 Sep '09

Greetings everyone, I am pleased to announce the first public release of my "Snow" library, available at http://alessiostalla.altervista.org/software/snow/index.php It is a declarative DSL for creating GUIs (Swing-only for now) built on ABCL 0.16. It supports Cells by Ken Tilton and MiG Layout (a declarative, CSS-like layout manager for Swing and SWT). As a bonus, Snow includes the GUI versions of ABCL's inspector, debugger and REPL. Snow is to be considered alpha quality. In particular, % of Swing supported is ridiculously small, and little testing has been performed. If you feel brave enough to play with it, let me know about your experience. Cheers, Alessio

[armedbear-devel] [from abcl-dev] Question on ABCL-SCRIPT
by Mark Evenson 15 Sep '09

15 Sep '09

Over on the abcl-dev blog OMouse said... I have a question: how do you change the eval/load-script stuff so it doesn't use the ABCL-SCRIPT package? I'm trying to add extensive scripting to a game but I'd like to be able to switch the package so that the scripter can use a huge bunch of variables without me having to :export them. Can anyone help with this question? I must sheepishly confess to not having much experience with ABCL-SCRIPT yet, but the question seems to ask for refinements in our implementation. Posting a reply on the [abcl-dev blog][1] would be great. [1]: http://abcl-dev.blogspot.com/2009/09/abcl-0160-released.html#comments -- "A screaming comes across the sky.

[armedbear-devel] Loading ABCL fasls from JARs
by Erik Huelsmann 14 Sep '09

14 Sep '09

Hi Mark, Today I was thinking about what to write in our bi-weekly blog. Then I remembered you committed the support for loading FASLs from JARs. Would you -or someone else- want to write a blog entry on the ABCL-DEV blog to make this feature world-known? Of course, if you don't have time, that's fine too. It's just that I suddenly figured it would be a nice subject to blog about. Bye, Erik.

[armedbear-devel] asdf regression
by Alan Ruttenberg 11 Sep '09

11 Sep '09

asdf::oos used to take a :verbose argument. It no longer does. This breaks some of my code (I'm trying to migrate to the latest abcl so I can test/use the jar file feature - thanks Mark!) (I've worked around it for now) -Alan

[armedbear-devel] Summarizing "In-memory compilation status"
by Erik Huelsmann 10 Sep '09

10 Sep '09

As pointed out, Alessio added some primitives required to add in-memory compilation. However, the rest of the thread seems to mix a number of issues and their progress. As a result, I thought a summary might be in order. There were several things "in-memory" versus "using files": 1. Compilation of functions in our JSR-223 support (Alessio changed ABCL's behaviour here) 2. Compilation of lisp forms into compiled functions 3. Compilation of lisp files into fasls With respect to (1): This is where Alessio changed ABCL's behaviour to use COMPILE instead of COMPILE-FILE, eliminating the use of a single temporary file. With respect to (2): Currently, ABCL uses a temporary file for each "compiland" (FLET/LABELS defined function, LAMBDA, DEFUN) in the forms to be compiled. This file is created with a ".cls" extention. After it's written, it gets loaded into the running jvm by loading the bytes in a byte array. That byte array is then resolved to a class. ABCL uses its own class loader to do so. Because the the bytes get written and read without this being required by the Java class loader, there should not be a need to write the bytes out to a file. After the file has been read into memory, the temporary file gets deleted. With respect to (3): Each "compiland" in a file to be compiled leads to a ".cls" file, which is created as a temp file, then read into memory and after that written into the ".abcl" file - which as noted is in fact a .zip file. The intermediate temp file is then deleted. This process too takes much more I/O (what if you're compiling to a network drive with this kind of I/O?!) then required. It's with respect to items (2) and (3) that I'd like to see things changed. In case of (2) there's no reason to send output to any type of disc, while in case (3) it would be beneficial to write our output straight into the ZIP file, instead of using intermediary files. I'm looking for a good solution to both cases. One of the things I came up with is some kind of "storage factory" which would be a function to be called which either generates a stream sending output to the ZIP, or an in-memory stream or a file-backed stream if that's still required. So, what are your comments to that? Bye, Erik.

[armedbear-devel] [OT] best way to structure and deploy a project
by Alessio Stalla 09 Sep '09

09 Sep '09

Hello everyone, I have a question which is not exactly pertinent with the development of ABCL, but which imho can start a useful discussion. Please forgive me if this is too OT. I have a project with sources in two languages, Java and Lisp. It is an Eclipse project, but the IDE does not make difference. The project is a library, not an end-user application. Currently it is structured as follows: src/java - Java source code src/lisp - Lisp source code lib/ - third-party libraries, both Java (jars) and Lisp (directories). The Java code is compiled by the IDE and put in an output directory. The Lisp source files are treated by the IDE as normal, non-source files, and copied verbatim into the same ouput folder as the Java classes. When I run the project from the IDE, I launch a class which compiles and loads the Lisp systems using asdf. This works for me locally, but thinking about distributing the project to users, this approach has some drawbacks: - Lisp files must be true files, they can't be in a Jar (asdf doesn't understand jars). - Lisp files are recompiled every time, since the IDE always overwrites the Lisp source files in the output directory. - If I make a jar, it will contain Lisp source files, not binaries, since binaries are unknown to the IDE. Ideally I'd like to do what ABCL does, i.e. create one big jar containing .class files and compiled Lisp files. Lisp sources could be compiled by the IDE or by a script, I don't care. Still, I would like to maintain the use of asdf (since some of my dependencies use it and loading them manually is too much of a hassle). I don't know how I can do this. I have also thought about leaving everything as-is, and when I'll distribute the library as a jar, have it extract at runtime the Lisp source files from the jar in a temporary directory and instruct asdf to search for systems in that directory. I will also need the lib/ folder to be in a known place, since asdf has to load stuff from there too (but this is less of a problem since I can make the library user configure that place, and use a sensible default otherwise). I am wondering if a cleaner approach exists, and if someone has experience in this regard. Cheers, Alessio

[armedbear-devel] In-memory compilation status
by John Pallister 08 Sep '09

08 Sep '09

Hello list, I'm interested in trying to get ABCL running (and preferably REPL-ing & compiling) on a certain cloud computing platform that has a JVM with no access to a file system. The Wiki page for JSR-223 and the sample code both mention that "compilation using the runtime compiler has been removed due to inconsistencies with evaluation and file-based compilation", since May '09. Browsing the mailing list archives suggests that people have been working on removing the need for temporary files since then, but I can't find any mention of "inconsistencies". The thread "Save-image w/Serialization - progress report" from April ends with Sig. Stalla in the process of implementing a byte-array-output-stream, then silence... Can someone comment on the state of runtime compilation, preferably entirely in-memory without reference to a file system? Basically I'd like to be able to compile stuff to a byte array, store the array as a blob in a memcache and/or other datastore, then pull it out again as required and load it via a custom classloader. Is this doable, or would it be easier to port ParenScript to Clojure (which is currently my Plan B)? Cheers, and it's great to see the ABCL project still going strong! John :^P P.S. If anyone is going to be in Hamburg at the weekend and wants to chat about this stuff, that'd be great! -- John Pallister john(a)johnp.net john(a)synchromesh.com
