[ANN] ABCL 0.21 released
On behalf of the developers of ABCL (Armed Bear Common Lisp) I'm glad to be able to announce the 0.21.0 release. ABCL is a Common Lisp implementation implemented in Java and running on the JVM, featuring both an interpreter and a compiler. The compiler targets the JVM directly meaning that its output is runnable ... 28 Jul 2010 16:15

ASDF-INSTALL + ClozureCL + SLIME + NTEmacs: cannot install package
Hello, I'm trying to make ASDF-INSTALL to work on SLIME (snapshot on 6 July 2010) on Windows XP. I'm following hints given at http://trac.clozure.com/ccl/wiki/HintsForAsdfAndOpenmcl and http://common-lisp.net/project/asdf-install/tutorial/index-save.html. I issue these commands at SLIME's REPL: (require :as... 28 Jul 2010 07:25

Today's NY Times has a long op-ed piece on that stupid monkey experiment. Oddly, I am only mentioning, not recommending it: analysis does not seem all that hot. kt -- http://www.stuckonalgebra.com "The best Algebra tutorial program I have seen... in a class by itself."

accumulate function in Lisp
Apologies in advance if this is a naive question, since I'm new to Lisp (my background is Forth). Is there an intrinsic function in Common Lisp which will iterate over each element of the list and apply a binary function between an integer and the list element. The return value should be an integer. I'm familiar... 25 Jul 2010 12:57

floating point output?
I guess it is somewhere in the CLHS, but I can't find it. How can I print a floating point number as the C printf function does it? I want always 1.0E-5, regardless of the number type of the argument: CL-USER > (format t "~g" 1e-5) 1.0E-5 NIL CL-USER > (format t "~g" 1d-5) 1.0D-5 NIL CL-USER > (format t ... 26 Jul 2010 01:56

disable debugger
I asked this before to be able to ignore divisions by zero and I was told this is implementation dependent (I use ECL 8.12); but can't I at least with a certain trick/code that is implementation independent ignore those or assign them a certain value when the division by zero occurs? I know with (setf * de... 27 Jul 2010 12:49

What's the spec for emacs lisp virtual machine ?
What's the spec for emacs lisp virtual machine ? Where are the complete set of virtual machine commands ? Where is the theory for such a virtual machine in the clearest description ? (not general theory, but one applicable directly to understanding emacs vm.) Does the emacs lisp operate as a stack push/pop o... 2 Aug 2010 15:50
