Which is the best implementation of LISP family of languages for real
world programming ?
http://wiki.alu.org/Implementation
Kindly pick one from commercial and one from open-source .
The criteria is :
libraries, gui interface and builder, libraries for TCP, and evolving
needs.
Please compare LISP and its virtues with other languages such as
javascript, python etc.
I put javascript in the context that it is very similar in its
architecture (homoiconic ie same representation for data-structures
and operations, ie hierarchical, which means nested-lists<=> n-ary
tree<=> binary tree<=> linked-list<=> dictionary<=> task-subtask,
and implicitly based on what C calls pointers, and at machine level
the indirect addressing of memory) to lisp family.
I put python in the context that it has the most extensive libraries
and shares the build-fix virtue of lisp highlighted by Paul Graham in
his books. Python is touted for its rapid prototyping of guis. It
syntax enforces stable format which guards against programmer malice
or sloppiness - so that there is a certain level of legacy code
readability.
Both have eval but not clear what is the implementation efficiency to
justify the habit of excessively using it.
Certainly, lisp/scheme are excellent for learning the concepts of
programming languages due to its multi-paradigm nature and readily
available code of the elementary interpreter.
Is there an IDE for these lispish-scheming languages ? Is there
quality implementation for Eclipse ? Emacs pre-supposes some knowledge
of these so that newbie can get stuck. Also, emacs help is not very
good.
Is there a project whereby the internal help of emacs (analogous to
its man pages) are being continuously being updated AND shared ? I
have never seen updates to the help. Perhaps, the commercial people
are doing it, even from the posts of the newsgroups, but the public
distros or these newsgroups have NEVER made such an announcement.
Explanations integrated into the help are more important than the
books - its like the wikipedia incorporated into emacs.
Is there support for the color highlighting of the code by hovering as
on this page ?
http://community.schemewiki.org/?lexical-scope
Which book/paper has the briefest minimal example of gui design along
XML nested/hiearchical elements with event-listeners for lisp/scheme ?
Thanks
I have used several available LISP systems such as the Gigamonkeys CLISP
Lispbox, and the Clozure Common LISP.
The system which I currently am using is the Franz Allegro Common LISP.
It is a commercial product; and so far I have had no problems with the
Allegro. (NB: I am using the Express version. I feel that the full scale
commercial license is not exceedingly expensive.)
(Right now I'm studying and working with the exercises in Peter Norvig's
book Paradigms of Artificial Intelligence Programming. I have done 16 of
the 25 chapters.)
This is not an advertisement. If someone wishes to criticize that
product, or if someone would like to suggest some other equally usable
implementation, of course please feel free to do so.

You said that you also want one implementation from open-source.
Amongst these, the best one according to my experience is the Clozure
Commmon Lisp.
(Disclaimer: I have not used the Embeddable Common Lisp, and not the
Armed Bear Common Lisp, and not the Clojure Commmon Lisp. The reason
for this is the fact that after beginnninng to use the Allegro, I felt
that I need not personally test any more Lisp implementations.)
Maybe it could be a good idea for someone to write an academic study of
all these available Lisp implementations. Even Interlisp still lives,
as it was recently noted in this newsgroup. (I did not check the
Google. Has someone alredy done so? Ie. studied the existing many Lisp
implementations?)
