To LISP or not to LISP?
I know there have always been tons of posts on game AI boards asking about
LISP, what it is, and if it's used in commercial games.
Given that LISP is used in few commercial games, is it worth becoming fluent
I am considering persuing it for two reasons:
A.) It is used in academic papers. Being fluent in LISP allows a person to
stay on top of the latest developments in AI.
B.) It can be embedded into game engines. I heard that Halo uses an embedded
LISP-like language for AI. Could embedded LISP-style languages benificial in
the long run?
I've been reading through LISP by Winston & Horn in my free time for the
past year, and I have to say that while I'm familiar with many of LISP's
features, when it comes to coding in LISP, I have the speed and
effectiveness of a slug.
What's with this language? There are too many parentheses and stuff. I
really like the transparency of lists in LISP, and have researched the
benefits of functional programming, but I'm still not convinced that I can
code anything in LISP with more ease than I could in C++.
Should I persue LISP until I am fluent in it? Any advice?

How about, when trying to decide "what is lisp" or to apply "lispp" to
some _thing_, we just go very low level and somewhat retro and mostly
As a straw-man: a lisp is any language implementation which includes a
run time system with some recognizably lispish types (cons pairs,
numbers, symbols) having their familiar properties (latent typing,
gc-based memory management), and implemented in a recognizably
traditional way (or a brilliant new way, worthy of being added to the
design space). In the language implemented, programs are expressed in
s-exp syntax and th...Which lisp for a (lisp) novice?

Trying to get a handle on CLOS, I grabbed my Kinkos copy of "On Lisp"
and jumped far ahead to the CLOS chapter. In section 25.1, there is a
footnote (which in the .pdf version is for page 349) which reads:
"Efforts to sum up Lisp in a single phrase are probably doomed to
failure, because the power of Lisp arises from the combination of at
least five or six features."

It exists a page that defines a tiny Lisp in Lisp very tersely.
I'm pretty sure to have seen it on the list about one year ago.
However I'm not able to find it again.
I wonder if Pascal Bourguignon exhibited this program, not absolutely
sure to remember.
Please have you got any idea about this small program ?

I'm deeply interested in Lisp. I'm learning it through Peter Seibel's
One comment I find a lot when people talk about Lisp is that Lisp is
wonderful, but CL has a lot of problems (problems I cannot understand
due to my newbieness). Now, I don't want to learn the wrong Lisp.
What do people mean by Lisp in this context? Is it Lisp 1, Lisp 1.5,
the particular dialect they used and fall in love with?
If this unidentified Lisp is so great, why don't they use it and avoid
all the pitfalls of CL?

Why would you want to do that? I'm sure many elementary Lisp and Scheme
interpreters in C are available on the internet. I assume that you mean
"common functions in lisp" and not "Common Lisp functions."

I don't use aquamacs anymore, but it respects .emacs IIRC. So if you
add a load path to your .emacs it should correctly work as it would in
any other variant. You may want to check out the bu...My road to Lisp (or why Lisp for poker software)
I was asked in a different thread to elaborate on why I chose Lisp to
write poker room software, whether I had to convince my backers, etc.
Poker room software, if you are wondering, is the client that you

client connects to.
The short answer is http://userpages.umbc.edu/~bcorfm1/C++-vs-Lisp.html

lisp textbooks of the time, like Toureztky's [I'm not too sure of all
the publication dates of all those, but I think that if they had
existed, we wouldn't have felt the need to write one of our own!]
We never published it... But wait, this gets more interesting!

compilers you know involves lisp-level program transformation, and how
much actually involves traduction to machine code ?

I am in a programming languages class, and Lisp has me freaked out! I
have a basic programming assignment where we make some functions and
then make a function EVALUATE that takes in a combination of those
functions as a list from a .data text file, and evaluates it.
Here's what is tearing me up: how do I program here? I am used to
using a text editor (pico) in our Unix system, and making a .c or .cpp
or .f or .p file, and then compiling it, and then running it, perhaps
with file or command line i/o. I can't figure out how to get this
I have my functions written, but I can't even test them out because I
don't know even know it all is supposed to be run.
In gcl, our Lisp environment, you enter it by typing "gcl", and then
exit it by (bye). You can type Lisp expressions at the prompt while
gcl. I am totally confused.
Can anyone help me get oriented, or is there a link? Our professor is
not that available to a working student, even by email.

I had an idea earlier, after reading the various threads and articles on
Reddit's switch to Python. The problem, people say, is that Lisp has a
library deficiency, so why not call Python's library code from Lisp?
A while ago, I needed to use Python as an embedded scripting language, so I
found out how to do this. Shelling out to Python was not an option because
it's grossly inefficient (and not Windows-friendly), but Python is actually
embeddable, in a fashion where it is called from a DLL, and remains
resident in memory until Lisp wants to execute Python code (as text)...Cross-lisp questions and my #lisp experience
Summary: I have recently tried to inquire about Common Lisp web
frameworks vs Scheme web frameworks on #lisp (I know, it smells like a
flamebait, but I really didn't mean that). This post is a summary of my
experiences, as well as a restatement of my questions.
I originally learned Lisp at age 10 (about 20 years ago), used it in
college (about 10 years ago) ant only returned to it about a year ago
due to Paul Graham's recent advocacy. Naturally, I figured that the
best hacker real estate is in web programming because this is the only
way to escape the long shadow of C/C++/Java. I sett...Lisp-1 and Lisp-2 in harmony.

Dwim stands for "Dispatch, in a way that is intelligent and meaningful".
The arguments to dwim are evaluated according to Lisp-1 rules. Any argument

in the variable or function namespace. If the innermost scope which has
a binding for the symbol has a binding in both namespaces, the tie is
resolved in favor of the variable binding. (I thou...
