0.1)            How can I browse ftp sites and their data without
                        using my own disk space (unless I want to keep
                        data), and locate files on ftp sites, given
                        pathname fragments?

Answer:

        This question might seem tangential at first (and I suppose it
is). But it is vitally important, as resources such as papers,
documentation, code and software tools become more numerous and
distributed.

        There is a set of Emacs-Lisp ("elisp") code, called
"ange-ftp.el", which makes 'ftp' use transparent within GNU Emacs (GNU
Emacs is available via anonymous ftp from prep.ai.mit.edu). This
package attempts to make accessing files and directories using FTP
from within GNU Emacs as simple and transparent as possible.  A subset
of the common file-handling routines are extended to interact with
FTP. Using these routines, one is able to access remote files and one
would any other local file, without having to write it locally to
disk. The result is an immense virtual global filesystem.
        The routines are available via anonymous ftp (naturally!) as
tut.cis.ohio-state.edu:/pub/gnu/emacs/elisp-archive/as-is/ange-ftp.tar.Z,
(incidentally, if you already had "ange-ftp.el", you could paste the

front of it, and copy the file.) My current version is dated 22
October 1991.
        Another useful bit of elisp is "saveconf.el". It saves the
Emacs buffer list and window configuration between editing sessions.
So, one can have several buffers, with several files open (as I
usually do), quit and restart Emacs, and have the state preserved,
cursor locations and windows included. Happily, it works well with
"ange-ftp.el", so that even remote files are restored (after possibly
having to prompt for passwords). "context.el" is also available via
anonymous ftp from cis.ohio-state.edu, as
pub/gnu/emacs/elisp-archive/saveconf.el.Z. Also look for
"tree-dired.el" which provides for hierarchical directory editing.
        Incidentally, it was very easy to produce references for the
above tools, thanks to another tool called "archie", developed at
McGill University. Dubbed a "resource discovery tool" by its authors,
it comes in very handy when one knows what tools are needed but not
their availability. Archie consists of a server for this information
(basically from a database of directory trees from "all known"
anonymous ftp sites, updated once per month), and a client, which may
be run via 'telnet' from the server machine itself (frowned upon...),
or from a standalone client available from that machine (...highly
encouraged, for the considerable host load win). Some clients even
perform ftp tasks based on user response to search results. There are
clients available for dumb and X terminals as well as for (of course)
Emacs. Poke around archie.mcgill.ca for a client and documentation.

        Porting these tools (or at least new interfaces to them) to
Smalltalk would be a great project. I'm working on it in my spare
time. I'd love to hear from any interested people.

1.2)            What Smalltalk archives are there?

Answer:

        There are many. Most of them simply archive GNU smalltalk, but
there are also a few large archives containing many interesting and
varied sources. All of the sites may be retrieved by invoking 'archie
smalltalk' (see above reference to 'archie').
        For convenience, descriptions of a few of the archives follow.
If you have a site/announcement you'd like included, please let me

Abstract to the working document

        This document describes an object-oriented description
language for musical parameters, events and structures known as the
Smallmusic Object Kernel (SmOKe) .  In object-oriented software terms,
the representation is described in terms of software class hierarchies
of objects that share state and behavior and implement the description
language as their protocol.
        The authors believe this representation, and its proposed
linear ASCII description in Smalltalk-80 syntax, to be well-suited as
a basis for: (1) concrete description languages in other languages,
(2) specially-designed binary storage and interchange formats, and (3)
use within and between interactive multi-media, hypermedia
applications in several application domains.

3.1)            Can someone recommend a good introduction to
                        Model-View-Controller concepts?

Answer:


Newsgroups: comp.lang.smalltalk
Subject: Re: MVC -- good introductions?
Date: 8 Mar 92 18:26:40 GMT
Organization: Florida International Univ.

Look at Chapter 10 in the following book that just came out:

Programming in an Object-Oriented Environment,
by Raimund K. Ege

Academic Press, Inc., San Diego, CA, 1992, hardcover,
ISBN 0-12-232930-9

To order call 1-800-321-5068.

(also: Academic Press Limited, London, United Kingdom)

It presents a complete and thorough introduction to all object-oriented
concepts. It contains a large
example/case study, and a comparison of major OO programming languages.

In addition, the book extends the object-oriented view
to all elements of the programming environment: data structures
and algorithms, programming tools, user interfaces, data bases and
software design.

Chapter 10 is on user interfaces: it describes and illustrates
the Smalltalk MVC paradigm (also: InterViews)

The book

        Smalltalk-80: A Practical Introduction
        (ISBN 0-273-03105-8)

        by Philip D. Gray & Ramzan Mohamed, 1990
        and published by Pitman (at least in the UK)

contains two chapters on interactive applications and the MVC.

I found it very helpful when first learning about the MVC.

Newsgroups: comp.lang.smalltalk
Subject: Re: how are st80 views and controllers used?
Date: 12 Mar 92 14:12:48 GMT
Organization: UTexas at Arlington, Linguistics

There are two papers on MVC that provide an introductory overview of
the pre-version 4.0 ST80 scheme.  Much of what's in them also applies
to version 4.0.  I understand that one of PPS's priorities in the
forthcoming version 4.1 will be improved documentation.  We'll see how
well they explain the new windowing scheme launched in version 4.0.
It would certainly be helpful to get an overview of what's going on
before plunging into the source code of the myriad new classes.

(1) A Cookbook for using the Model-View-Controller User Interface
Paradigm in Smalltalk-80 by Glenn E. Krasner and Stephen T. Pope,
ParcPlace Systems, copyright 1988.

(2) Applications Programming in Smalltalk-80: How to Use
Model-View-Controller (MVC) by Steve Burbeck, Softsmarts, Inc.,
copyright 1987.


The second paper is probably no longer available.  I think Softsmarts
is the company that used to sell a version of Smalltalk for 80286
machines but went out of business some years ago.  The phone number on
the paper is listed as 415-327-8100 (Palo Alto, California).  You may
try asking ParcPlace (or, less likely, Digitalk) if they have copies
of Burbeck's paper.

3.3)            What are the "blue book", "purple book", etc?

The books are actually cream or tan. The color referred to is the color

The purple book is an update/revision of the blue book, with the
section on the abstract bytecode machine omitted (because it was out
of date, according to Adele).

3.4)            Who are some employers of Smalltalk programmers?

Answer:


Newsgroups: comp.lang.smalltalk
Subject: Smalltalk employers file
Date: 18 Sep 92 16:32:43 GMT
Organization: University of Illinois, Dept. of Comp. Sci., Urbana, IL

        I've noticed a rash of job offers here (I approve of them) and
decided that I should distribute my list of companies hiring
Smalltalkers.  I have collected this over the years and give it to my
students.  However, the size of the list is significantly greater than
the number of my students, so I decided to make it public. I would be
happy to add entries, remove entries, or make other changes to it.  If
you are an employer then you might want to take a look at it to see
whether you like what I say about you, and let me know if you don't.
I'll change it, though I like *short* entries and have shortened
almost everything in here.

        The file is in the Smalltalk archive in
/st-docs/smalltalk-jobs.  You can ftp it from st.cs.uiuc.edu or you
can use the e-mail archive server (see the recent FAQ).  Europeans
note that this will automatically show up in the Manchester archive in
a day or so.

Organization: DB and ES Subdivision, TU Vienna

Ok, here are the comments I received about the Smalltalk Report.
While the sample base is quite small, the response seems
overwhelmingly favorable.  Thanks to all who responded.

        Markus

---------------------------------------------------------------------
I have subscribed since the first issue and I find it to be an excellent
combination of theoretical and practical articles. John Pugh (of LaLonde
and Pugh) is the editor.

On the other hand, I will warn you to expect subscription headaches with
SIGS Publications. They are probably the worst I've ever dealt with and
our technical librarian agrees. They are barely capable of processing a
renewal let alone a new subscription or problem.
---------------------------------------------------------------------
We subscribe, last issue was about 20 pages, 2 articles, 3 columns.
I would call it a must read publication.
---------------------------------------------------------------------
I think its pretty good. (But then I should mention, I write for it!) It tends
toward intermediate, with lots of practical tips and examples.

(This was not an answer to my question, but I include it for completeness.)

3.6)            Is there a GNU Smalltalk tutorial?

Answer:

        Yes.


Date: 28 Feb 1993 03:00:10 GMT
Organization: Sun Microsystems Inc., Mountain View, CA

        Andy Valencia has very graciously provided an extended
tutorial document describing the Smalltalk language with respect to
GNU Smalltalk.  It covers a wide variety of topics, and provides a
general introduction to object oriented programming concepts.

        You may FTP a copy from the usual GNU locations in a few days
(after it has propagated).  Currently, it may be found at:

    prep.ai.mit.edu: pub/gnu/smalltalk-tutorial.ps.Z  (postscript)

-or-

    prep.ai.mit.edu: pub/gnu/smalltalk-tutorial.txt.Z  (ASCII)

Check it out -- this looks really good!

   Just curious. Thanks

        This is probably in the FAQ list [it is now...  --crl], but
here goes anyway.  GNU Smalltalk tries to be syntax compatible with
the language described in the blue/purple book (ST-80: the Language*).
I think the only discrepancy is that GNU Smalltalk doesn't allow block
local temporary variables.
