I am a college student who dream of being a great programmer some day.
Now I am quite familiar with C, Perl, awk, shell programming , while not
quite familiar with c++ and java. I installed linux on my PC and played
happily with it, now reading books on UNIX system calls.
I was told that to be a good programmer, you must learn LISP, although
you might never use it in your real life programming, it will teach you
how to make good programs, is it true?
If so, where shall I start to learn LISP, Lisp interpreters does not seem
to install in my LINUX system. But I guess that I shall be able to program
lisp in Emacs, right?
could anyone give us some hints on starting to learn lisp???
Thanks

I can only speak for myself, but I have learnt much more about
programming by learning Lisp. The things I have learnt by programming
in Lisp also benefits my programming in other (lesser) languages. So
even if you are unlucky and don't end up in a place where they do
development in Lisp, you benefit by learning Lisp (as I see it).
However, several places hire Lisp programmers, even in the Real Life,
so I presume (and know) they use it in Real Life :-)

I would recommend, if you have previous programming experience, that
you get hold of a good Lisp book (e.g Paul Graham's "ANSI Common Lisp"
which I liked a lot) and get hold of a good Lisp environment suitable for
learning. Luckily there are several good Lisp environments for Linux,
where I tend to prefer Franz' Allegro Common Lisp which has a Trial
Edition. Xanalys also has a nice environment in Lispworks. There
also exist a few free (as in speech) Lisp compilers which can be used
(CLISP, CMUCL, Poplog, ..).

Every additional computer language and programming paradigm you
are exposed to makes you a better programmer, as you will slowly
acquire different ways of thinking about problems.

Isn't the Steele book the definitive text on Lisp? Anyway, it's
probably the best reference manual.

YMMV, but I use the HyperSpec as reference manual. You may find it at
http://www.xanalys.com/software_tools/reference/hyperspec.html
(I also have Steele (cltl2) as backup in case I need another
explanation to back up the one in the HyperSpec, but I don't
have the URL where I found it handy)

One reason I recommend Common Lisp is that it covers more paradigms than
any other language I'm familiar with.

It used to be the reference. It never was a good book to learn Lisp
from. I have a copy, which is sometimes helpful, but I use the
Hyperspec and the appendix of "ANSI Common Lisp" more often.
I have no good way of judging beginning Lisp books, since I've learned
it in my own way over many years, but Graham's looks as good as any.

Thanks for all the kindly replies.
Now I had download CLisp from www.franz.com and installed it successfully.
I also borrowed 3 books on Lisp,(Steele, Norvig,Abelson et al.)
Now I have all the stuff needed to get my hands dirty with Lisp. :)
Any hints on how to learn Lisp effectively?
Thanks again!

You can't go wrong with Norvig's book. Start with Parts I and III.
Abelson et al. uses Scheme and not Common Lisp so it will be of limited
value to learning Common Lisp. It is a great book though.

Think of a program you'd really like to write, then start to write it.
Pester this group when you get stuck. Half way through, realise that
you could do it a lot better given what you know by then. Throw it away
and start a different problem/language that looks more interesting.
Publish anything that you do complete on the net under the GPL. Iterate
'til you grow old and die.

I'd like to take this a bit further.
Many programs require structuring, sorting and searching of data, and
this can be done elegantly and efficiently in Lisp. But if one has a
C-like programming background, the entire code/data structures are often
constructed in a "conventional" manner, so that the underlying power of
Lisp does not shine through.
I would like to emphasize the non-mechanical use of Common Lisp. By that
I mean code that is not directly mappable, ie has no single simple
relation to the data it manipulates.
To get a better feel of what can really be done with Lisp, you could
choose some domain where applications are difficult to implement, or
even demonstrate, in most conventional languages. Examples are
planning, goal-searching, and simulation, which you will find in the
books by Winston&Horn and Graham.
Such examples show the kind of thinking you must apply, before going to
the keyboard. They also illustrate an earlier comment (by Erik Naggum,
about reinventing Lisp), that with other languages, you must write a
horrendous amount of utility routines before you can even start on your
actual problem.

that's odd. Linux systems are very well supported by Lisp systems.
which Linux are you using? if you are using the programmers' favorite

package system, and Franz Inc offers a trial edition for Linux that you
basically download and install.

you will, but Emacs Lisp is a _really_ ancient dialect of Lisp, with lots
of interesting stuff missing. the modern Lisp is Common Lisp.

IMO any programmer should learn a Lisp language. I would be happy if I
started earlier really using it.

Strange, I installed CMUCL, have a Franz Allegro trial version running
and installed Xanalys (was Harelequin) Lispworks. First the trial
version and now the professional version.
System here Debian slink/potatoe, Kernel 2.2.15, glibc 2.1.2.
The following books have opened my eyes for the beauty of Lisp. Paul
Norvigs Artificial Intelligence Programming and even move Grahams ON
LISP.

Hi,
More than Lisp, I would recommend learning as many languages as
possible. In fact (and I will probably be shot at dawn for saying this
on this group) I can see arguments for learning either Haskell (or ML)
or Scheme before Lisp:
- Lisp is great because it supports so many different styles of
programming. Recently I translated an interpreter for a small language
from C to Lisp (the reason isn't important) and although the result was
very ugly Lisp code it was not difficult to do. In other words (rather
like moving from C to C++) you can continue programming "as you used to"
without coming to understand the good bits of Lisp. Learning Haskell
instead would protect you from yourself and force you to think about
functional programming.
- A book that will probably improve your programming significantly is
Abelson + Sussman's "Structure and Interpretation of Computer Programs".
This is an acknowledged classic that uses Scheme. Scheme is a Lisp,
historically, but these days it's treated as separate language. You
might find that working through that book, with Scheme, is the best way
to become a better programmer. If you take this route, however, I would
strongly recommend returning to Common Lisp - Scheme is a very "slimmed
down" version of Lisp and Common Lisp includes many many features that
make programming more productive (someone else, Erik I think, said in
another post that people "reinvent Lisp" - that's especially true of
Scheme programmers, imho).
As for starting to program in Lisp - check out www.lisp.org for much
useful info. Get both CLtL2 and the hyperspec in electronic form as
references, if you can (links at www.lisp.org). Graham's book "On Lisp"
is not intended for beginners, but I would suggest you try and read it
as soon as you feel comfortable with the language.
I use CLISP which is in included in SuSE Linux - you can download
binaries for most platforms from www.cons.org. Allegro give away a
version of Lisp for Redhat (not Debian, afaik) and CMUCL is in Debian.
More info at www.lisp.org. You can cross-install packages for different
Linuxes (eg CMUCL is packaged for Debian, but you can install on other
unixes) but it's not always trivial - ask Linux groups for specific
details (the CLISP binaries are generic Linux, afaik, but you may need
to check which C library you are using - maybe I'm the only dinosaur not
running glibc these days).
Andrew
PS There's a sketchy review of programming languages on my web pages at
www.andrewcooke.free-online.co.uk/index.html if you want further
language recommendations (follow the link in the text).
PPS As a self-taught programmer (no CS degree) I understand what you
mean about wanting to become a better programmer. The great thing is
that you continue to improve and improve - either I'm a very slow
learner or it just never stops :-)

More or less, yes.
Of course, I wouldn't say "must learn Lisp" but rather "is privileged
by being able to learn Lisp."
Lisp is fun!
As for using Lisp, you will find a lot of prejudice against Lisp going
around which might discourage you from using it for real life
programming. However, this is mostly just prejudice and nothing more.

Don't use Emacs Lisp for anything but programming Emacs. It is an
ancient and inferior Lisp.
> could anyone give us some hints on starting to learn lisp???
"Structure and Interpretation of Computer Programs" (SICP) by Abelson
and Sussman with Sussman talks about programming in general, using
examples in the Lisp variant Scheme. There are many implementations
of Scheme for Linux. (scsh, guile, scm, stalin, ...)
Scheme is a _very_ small Lisp, suitable for learning, but not for much
else. (In my opinion, of course) Some claim that when learning Lisp
you should ignore Scheme and go right to Common Lisp. I think Scheme
is worth learning, but only because SICP is a damn good book and you
should have a Scheme system handy for trying out the examples and
exercises.
"ANSI Common Lisp" by Graham is about modern Common Lisp, which is the
Lisp to use for anything serious. It is a tutorial type book. There
are many variants of Common Lisp, most of which works on Linux. Look
at http://www.cons.org/, http://www.franz.com/ and
http://www.harlequin.com/
"On Lisp" by Graham is a more advanced tutorial type book. I found
the most interesting part of the book was about Lisp macros. Lisp has
a macro system that is above and beyond _anything_ you can find in any
other language. This book explains them and gives lots of examples.
Some claim that it goes way too far in using macros.
On the reference side, the Hyperspec is it. This is a reworking of
the official language standard into HTML and heavily cross-linked.
It is really a wonder to behold and a joy to use.
"Paradigms of Artificial Intelligence Programming: Case Studies in
Common Lisp" (PAIP) by Norvig is a _very_, _very_ good book. You
should have read "ANSI Common Lisp" or a similar book first though.
The title of PAIP may seem daunting but don't let it stop you. The
book is very readable, once you are able to read Lisp programs
semi-fluently.
I just did a web search to get the title right, and found the
following quote which I fully agree with:
I tell my students to think of Steele's book as the Oxford English
Dictionary and Norvig's as the complete works of Shakespeare. -
Prof. Wendy Lenhert (Massachusetts)
"Steele's book" in the above is "Common Lisp the Language". (CLtL)
This a reference type book. Unfortunately it is out of date, so
personally I use the Hyperspec only. (References need to be up to
date)
CLtL has a few chapters that never made it into the ANSI standard.
Some day I should read them.
If you have decided at this point that Lisp is your future main
programming language, wether anybody pays you for it or not, you might
want to look at "The Art of the Metaobject Protocol" (AMOP) by
Kiczales, Rivieres and Bobrow.
There is also a book called "Lisp" by Winston and Horn which I have
never read but which is often recommended by others.

On second thought: I think I recommend reading PAIP _before_ OL since
this will make you more critical of OL. OL is good, but _should_ be
read critically.

I feel that ideally you should learn at least one major language from each of
the major forms, and even some things that aren't exactly really languages.
My current selection would run (in no particular order):
Lisp, FORTH, C, Ada95, OCaML, assembler, MS Excel macros
With this as a basis, there are options: Snobol, Eiffel.
And then the "hot" languages: Java, HTML, XML, MS Visual Basic, C++ {these
are in what I think of as the appropriate order [N.B.: This list changes
frequently!]}
That's ideal. That's also a multi-year program. Most folk pick a small
selection from that on various bases (e.g., what's supported locally).

I was a bit surprised to see MS Excel macros here - I've never used
Excel, but will be installing it soon at work. Why did you include it?
Are Excel macros something like SQL (ie could that last item have been
Prolog or SQL?) (apologies to Prolog users ;-)?

Thanks. My post probably made more sense to the telepathic amongst you
who realised I was confusing Excel and Access... (Access is the DB
product, I think). Anyway, in that case, I guess I'd add Prolog to the
original list (although I suppose once you've read almost any Lisp book
you'll have met the basics - all three I've read (Norvig, A&S, On Lisp)
seem to implement some kind of Prolog)

I think this is an interesting way of looking at the world. Although lisp is
`cool' (that is common lisp and this is in comparison to cool ;) I'm sure
there are many other things that would make you (or me or whoever) a better
programmer than simply learning to programme in lisp. Learning lisp is a good
start tho'.
