flets in macros 18 30 (12/17/2004 12:50:47 PM) comp.lang.lisp I'm writing a macro, map-collect, that performs a mapping function over a list or lists and binds COLLECT and NEXT to functions that allow the following: (map-collect mapcar (item '(1 2 3 4 5 6)) (collect it... Chris

Slot accessors and syntax 47 25 (12/14/2004 10:53:50 AM) comp.lang.lisp Coming from C#, the most painful aspect of Lisp seems to me to be using objects. Yes, the system is more powerful. But the syntax just isn't made for it. When I have an object foo-inst of class foo, with slots ... Chris

Replacing subsequences 21 33 (12/10/2004 12:38:22 PM) comp.lang.lisp I had a need just now to replace one substring in my string with a different substring, of a different length (for quoting parameters to SQL queries, incidentally). It appears that accomplishing this isn't stra... Chris

Lisp code security 45 32 (12/5/2004 12:13:52 AM) comp.lang.lisp Hi everyone, I'm interesting in defining a subset of Lisp that is safe in the sense that any arbitrary code written in the subset can be executed without fear of the code compromising the security of the syste... Chris

Interesting simulation ideas 20 23 (12/4/2004 10:18:38 PM) comp.lang.lisp There have been a few newbies (including me) programming simulators recently, and after doing my rather boring Battleship simulation, I was wondering if there's something a bit more interesting out there to sim... Chris

Battleship simulator 5 41 (12/1/2004 8:14:57 AM) comp.lang.lisp Hi everyone, I've programmed a simulator for the game battleship (description included in file) so I could try out a few different strategies (idle curiosity, mainly) and I thought I'd let you all know in case... Chris

Changing word break behavior in emacs 6 82 (11/25/2004 8:52:34 AM) comp.emacs Is there a way to change the way Emacs treats word breaks? For instance, coming from a windows background, it really annoys me that M-f puts you at a different point than M-b. I'd also like to be able to tell i... Chris

Lispers and Emacs 8 23 (11/24/2004 12:39:27 PM) comp.lang.lisp Hi all, I've spent the past evening hacking on SLIME. I was roused into an Emacs frenzy by a building frustration and a straw: finding the slime-indent-and-complete-symbol function. I had never really been abl... Chris

CL subset? 16 32 (11/21/2004 1:44:13 AM) comp.lang.lisp I've read that a program can be a conforming subset implementation of CL in the case that any programs written in that subset will run as intended, unmodified, on a fully conforming CL implementation. The prima... Chris

Lisp collections 103 44 (9/21/2004 3:04:01 AM) comp.lang.lisp Coming from a C# background, one thing I've begun to miss in lisp is a nice, flexible array/collection feature. Let me describe the .NET ArrayList class. It's built over a fixed-length array that's reallocated... Chris

FORMAT question. 22 22 (12/11/2004 10:55:56 AM) comp.lang.lisp Hi. How format-string should look like? (format t format-string 1 2 3) ==> 1 2 3 2 1 Is this possible? Regards, Szymon. ... r5z-u28s_g1d (88)

(; comment suggestion) 22 33 (12/12/2004 6:57:57 PM) comp.lang.lisp Many times I and others have had problems with comment lines - if they get word wrapped, there's an error message. I have a suggestion to alleviate this problem: make a semicolon a function, just like the rest... sky1 (37)

Python, XML. and now .Net? 6 38 (12/12/2004 10:25:19 PM) comp.lang.lisp Following a link from LtU today, i cam across CodeDom for .Net : http://www.15seconds.com/issue/020917.htm What this seems to be is a method of parsing abitrary source code into a Tree Structure (like s-exps... drewc (225)

Another question, pass a function to the function pointer 4 36 (12/13/2004 11:19:36 PM) comp.lang.lisp Now, if I have a pointer to a function defined, how can I pass a function to the struct. For example, can I use a defun? (defun test-c (a-the-int) (print "--X")) (def-c-struct test-pointer-function (a int)... berlin.brown (230)

CLisp case sensitivity 145 33 (12/14/2004 3:49:17 AM) comp.lang.lisp I've read that Common Lisp is case sensitive, but have also noticed that Allegro has a way of creating a case-sensitive image. Can the same thing be done with clisp (on GNU/Linux)? ... tgagne (595)

Garbage Collection and Games #3 21 34 (12/17/2004 10:15:33 PM) comp.lang.lisp Hi all, I have recently been doing some research into Garbage Collectors, and playing around with CMUCL's GC. Since there has been a lot of disscussion about Lisp and games in here over the last few months, I f... philip.haddad (66)

Argument evaluation order 13 34 (12/18/2004 11:00:13 AM) comp.lang.lisp hi, At the moment i'm reading the book Successful Lisp and read this: "When a list form is a function call, its arguments are always evaluated in order, from left to right. As in other programming languages, ... chrizel (2)

converting dynamic to lexical scope 7 24 (12/19/2004 1:28:34 PM) comp.lang.lisp hi i have this function i wrote for a lisp which uses dynamic scoping. QUESTION: How would i convert the function to use lexical scope? Can it be done with a macro? Or is there some other trick that i should... jimka (490)
