Multiple evaluation 20 29 (7/25/2008 5:28:02 PM) comp.lang.lisp This is not a question about preventing accidental multiple evaluation in macros, but rather about forcing multiple evaluation in functions. Let's say I want to create a list of 5 random numbers like this: (m... Ari

Stack access--Am I looking for continuations? 6 23 (7/8/2007 11:29:17 PM) comp.lang.lisp I'm writing a recursive function, and I find myself asking, how many invocations of this function are currently on the stack? What's the value of a local variable 5 invocations down the stack? I could give the... Ari

Setting content-type and encoding on XMLHTTPRequest 0 172 (12/23/2006 3:22:25 AM) comp.lang.javascript When I send an XML document over XMLHTTPRequest, IE encodes it in UTF-16, but fails to set the "encoding" part of "Content-Type:" header. According to rfc 2616, default encoding in HTTP is ISO-8859-1. Parsing a... Ari

intrinsic size of an Image 13 20 (12/5/2006 12:23:27 AM) comp.lang.javascript Image.width returns the width of an image as it is displayed on a browser page, which may be different from the image's intrinsic size if the 'img' element had a 'width' attribute specified. Is there a reliabl... Ari

method combinations 13 29 (7/18/2006 2:01:49 AM) comp.lang.lisp I have a class that has methods specialized on it that are expensive. I want to inherit from this class to include slots that can hold precomputed values of these expensive methods. I want to make it so that if... Ari

loop with an optional limit? 3 32 (7/16/2006 7:12:43 AM) comp.lang.lisp I'm trying to write a function that reads forms from a file. The caller may optionally specify a maximum number of forms to read; if that variable is null, the function should read forms until eof. Is there a w... Ari

Silly argument for a unix DIRECTORY: 6 35 (7/13/2006 11:48:33 PM) comp.lang.lisp I get this warning when I pass a string as :directory to make-pathname in CMUCL: Silly argument for a unix DIRECTORY: "/home/ari/foo" What makes this a silly argument? Ari. -- Elections only count as free ... Ari

multiple namespaces 5 24 (6/26/2006 7:57:11 AM) comp.lang.lisp Common Lisp has separate namespaces for functions and values. What are the tradeoffs? There are two cases I've seen where one is easier to use than the other, but I'm sure there must be others. One case is whe... Ari

What's more idiomatic? 29 33 (10/20/2005 7:23:26 AM) comp.lang.lisp Performance issues aside, which one of these expressions is more idiomatic in Common Lisp? (mapcar #'foo (mapcar #'bar list)) (mapcar #'(lambda (i) (foo (bar i))) list) Ari. -- Elections only count as free... ari

Variable capture 9 21 (10/18/2005 9:00:42 PM) comp.lang.lisp Is it accurate to say that variable capture can only occur in macros that introduce local variable bindings? IOW, can capture occur in a macro that has no LET operators or macro calls that expand to LET, like D... ari

MAP (and variants) vs LOOP - Popular opinion observation? 60 31 (8/2/2006 11:17:40 PM) comp.lang.lisp It seems to me that popular opinion leans toward LOOP in favor of map and variants where either would apply, for the following reasons, to mention a few: 1. LOOP is more readable 2. LOOP is more efficient 3... j_mckitrick (424)
