[armedbear-devel] Spaces in pathnames (jar:file:/x/y/z/a space/...)
by Theam Yong Chew 11 Jul '11

11 Jul '11

Dear ABCL developers, While ABCL can handle spaces (& others) in file pathnames just fine, a space in jar file pathnames still doesn't work. I have confirmed this on Linux, Mac and Windows. An example using Cygwin, $ java -jar abcl.jar Armed Bear Common Lisp 0.24.0 Java 1.6.0_20 Sun Microsystems Inc. Java HotSpot(TM) Client VM Low-level initialization completed in 0.625 seconds. Startup completed in 4.438 seconds. Type ":help" for a list of available commands. CL-USER(1): (load "jar:file:e:/My Dropbox/temp/a space/hello.jar!/hello.abcl") #<THREAD "interpreter" {9AC0F5}>: Debugger invoked on condition of type FILE-ERROR Failed to create URI from 'e:/My Dropbox/temp/a space/hello.jar': Illegal character in opaque part at index 10: file:e:/My Dropbox/temp/a space/hello.jar Restarts: 0: TOP-LEVEL Return to top level. (and yeah, this particular path already has a space character in "My Dropbox" along with my original intended "a space" folder) By the way, thanks for the :wildcard directory support (I've only just tested that, it works for me now!). Yong.

[armedbear-devel] json-rpc?
by Axel Rauschmayer 27 Apr '11

27 Apr '11

I think ABCL would make an excellent Ajax server. As such, it would have to support json-rpc. Any suggestions as to how to make this happen? The first part is obviously the server, where the two choices that I can see are Hunchentoot and a servlet container such as Tomcat. In the latter case, I would expect to use a technique like abcl-web (which seems a little bit complicated, but doable). The second part is the JSON parsing. How would I do that? Via CL-JSON? Via Yason? Via a Java library? Sorry for these newbie questions. I’m just getting started with Common Lisp and ABCL. Thanks, Axel -- Axel.Rauschmayer(a)ifi.lmu.de http://www.pst.ifi.lmu.de/~rauschma/

[armedbear-devel] translate-logical-pathname downcasing paths inconsistently
by Jonathan P. Bona 27 Feb '11

27 Feb '11

As the following code and transcript demonstrate, translate-logical-pathname appears to be downcasing paths inconsistently: ;;; test.cl (setf (logical-pathname-translations "foo") '(("foo:bar;*.lisp" "/FooRoot/bar/*.lisp") ("foo:*.lisp" "/FooRoot/*.lisp"))) ;;; In the following pathname translation, the entire path is downcased (pprint (translate-logical-pathname "foo:bar;foobar.lisp")) ;;; In each of the next two, the entire path EXCEPT for the host is downcased -- ;;; the host is unchanged (pprint (translate-logical-pathname "foo:foobar.lisp")) (pprint (translate-logical-pathname "foo:Foobar.lisp")) --- Armed Bear Common Lisp 0.24.0 Java 1.6.0_22 Apple Inc. Java HotSpot(TM) Client VM Low-level initialization completed in 0.478 seconds. Startup completed in 1.386 seconds. Type ":help" for a list of available commands.

[armedbear-devel] :case :common
by pjb＠informatimago.com 27 Feb '11

27 Feb '11

CLHS says: 19.2.2.1.2.2 Common Case in Pathname Components For the functions in Figure 19-2, a value of :common for the :case argument that these functions should receive and yield strings in component values according to the following conventions: * All uppercase means to use a file system's customary case. * All lowercase means to use the opposite of the customary case. * Mixed case represents itself. Note that these conventions have been chosen in such a way that translation from :local to :common and back to :local is information-preserving.

The customary case is lower case (case significant on this particular file system, but 99.999% of the files on unix are lower case). Therefore I would expect to get #P"test.lisp" Notice that: (make-pathname :name "test" :type "lisp" :case :common) should produce #P"TEST.LISP" and that: (make-pathname :name "Test" :type "Lisp" :case :common) should produce #P"Test.Lisp" And that I understand "yeld strings in component values" to mean that the processing should be done on each parameter independently. -- __Pascal Bourguignon__ http://www.informatimago.com/ A bad day in () is better than a good day in {}.

[armedbear-devel] abcl and maxima
by Reinhard Oldenburg 27 Feb '11

27 Feb '11

Dear All, after quite a while I came back to running maxima on abcl becaus there is an increasing interest in incorporationg maxima in Java based projects. Some time ago Mark explained that in principal loadinf form jars can be done, but it seems that it ned some time to twea maxima-load.lisp so that it loadsfrom a jar containing all the abcl files. Has anything happend on this in the meantime?

[armedbear-devel] Support for -- in parameter lists
by Ville Voutilainen 20 Feb '11

20 Feb '11

It's common that a double-dash (--) alone can be used to tell a command line parser to stop interpreting further arguments. So, I implemented that very feature for ABCL in r13226. Lo and behold: given a test snippet, saved in cmdline.lisp: (loop for item in *command-line-argument-list* do (format t "got arg ~a~%" item)) we can do ./abcl --batch --eval '(load "cmdlinetest.lisp")' -- hops hups jee jee --eval '(format t "hah~%")' -- -- -- Armed Bear Common Lisp 0.25.0-dev-svn-13225M Java 1.6.0_22 Sun Microsystems Inc.

Hi "all", thanks for the great amount of answers. Seems that the best way to handle my problem is to pack the necessary file within the jar file.

Replace "for each top-level form" with "for each function definition" and it's 100% correct ;) A. _______________________________________________ armedbear-devel mailing list armedbear-devel(a)common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/armedbear-devel

[armedbear-devel] newbie question
by Lukas Georgieff 16 Feb '11

16 Feb '11

Hi, I am new to ABCL and have a question to it's capabilities:My goal is to load an exsting part of a system coded in lisp into Java and to use the lisp code as basic library for a java application. Currently my approach is to load the lisp code with:Interpreter interpreter = Interpreter.createInstance();interpreter.eval("(load \"my-lisp-code.lisp\")");... So the lisp code must be present in the project every time it is running.Is there any chance to translate the lisp code to a Java source file by using ABCL? So it would not be necessary to provide the lisp code in the java application after it is translated once. Best regards Lukas

[armedbear-devel] 'unsafe-p-removal' branch integrated in trunk
by Erik Huelsmann 15 Feb '11

15 Feb '11

Just a second ago, I've merged the unsafe-p-removal branch to trunk. It's been sitting in its own branch, completed, for about 4 weeks, waiting for us to release 0.24.0 - which cleared trunk for destabilizing changes. The purpose of the change is to push the responsibility of maintaining stack consistency (ie. prevent 'stack inconsistency' class verification exceptions) to pass2. Before, this responsibility was a joint effort between pass1 and pass2, with a heavy focus on pass1. However since we started inlining local functions, not enough information is available in pass1 anymore to execute its responsibilities correctly. In pass2 all information is available to take on this responsibility and with some additional infrastructure, that's what this change achieves. Due to the fact that quite a bit of pass2 code has been refactored, the change could have a slightly destabilizing effect on trunk. Please help test your software on ABCL to make sure we release - when we do - code as stable as ever! Bye, Erik.

Hi, In order to see if we have enough material to contend timeslots in GSoC2011, I've started a list of proposed projects right here: http://trac.common-lisp.net/armedbear/wiki/GSoC2011 Please, if you have Trac access feel free to nominate and describe your project directly on the wiki, or send your reaction as a response to this one if you don't! Bye, Erik.
