Conference hydra::amiga_v1

Just to piggyback on John's question (sorry John):

Does a smalltalk implementation exist for the Amiga?  I would love to play
with it at home.

	Paul

I thought I saw something listed in the Amiga product guide from AM; I'll
check when I get home.

There is a smalltalk on Fred Fish 37, although I haven't had time to
download it and to play with it.

    There's a real challenge for you! why not use "C" and write an
    ADA compiler for the Amiga?  What better way to learn ADA! And,
    you won't have to worry about what to do with all your spare time
    for about the 2 years.

You know, it's funny you said that. I dug up a book I bought back in 1987
named "Software Engineering with ADA". It's the complete ANSI standard
with "oo design and methodology" chapters.

I thought this morning "hmm, maybe I could write a compiler". As I shook
my head I almost fell down the stairs. Took that as a hint...

    I'm currently taking a summer course at ULowell in c++. Before the
    course began I contacted the professor to find out what compiler they
    were using - they weren't - it's a provide your own (suggestion was
    to purchase Borland). When I told him I had an Amiga, he suggested I try 
    porting g++. Fortunately, someone else had already ported it to VMS and 
    ULowell also has recently installed it on their Ultrix machine. So the
    necessity of having it running on the Amiga has disappeared.

    I had started with the port. So far, all I've managed to do is:

    - get the g++ tar.z file from decwrl
    - uncompress it
    - untar it on vms
    - generate an lharc file and
    - download all 1.5 meg of it to my 500. (2 hour download!)

    I'm just at the point where I'm playing with the makefile to see how
    it differs from Lattice lmk.

    Before I go any further with this, I figure I'd ask if anyone else were
    attempting a port or had ported g++ to the Amiga. I haven't seen anything
    on usenet. I'll most likely continue with it, but how successful I'll be
    depends on my available time to hack. I'm sure the course will be long
    over by the time I get done or give up.

There are also available on Fish disks:

OPS5c		- an OPS5 to C compiler (FF358)
Scheme		- interpreter (FF149)
SBProlog	- Prolog interpreter/compiler (FF140,FF141)
PowerLOGO	- interpreter (FF377)

I wonder if there is a more recent version of SBProlog or if CProlog was ported
on Amiga.

G'day!
 
I have seen postings in this group about a possible Amiga version of Eiffel
(which is a recent object-oriented language & very nice to use).
 
There is a new strongly typed object-oriented language being developed
at the International Computer Science Institute at Berkeley.  This new
language is called Sather.  Sather is a variant of Eiffel, syntactically
very similar but simplified and optimized.  They claim that Sather has
performance 4 to 50 times that of Eiffel.
 
The good thing about Sather is that its in the public domain.  Full source
for a Sparc beta version is available from icsi-ftp.berkeley.edu in directory
pub/sather.  Sather (like Eiffel) compiles to C and thus should be fairly
portable.  The run-time-system should be the most difficult part to port to
the Amiga.  The Sather compiler itself is written in Sather, thus source in C
(generated from Sather) is included.
 
Documentation (.ps) is also available from the ftp site.
 
I'm interested in porting but if somebody wants to take charge of any
serious attempt, do so.
I think we can give up hope of compiling anything serious with Lattice C,
I might try using GCC or compiling it on a Sun-3 and using the SOBJA program
(from the Amiga GCC port) which converts Sun-3 object code to Amiga object
code.

There will be an Amiga Eiffel.  It is in the beta testing stage now.

There are some problems that I have with Sather.  First of all it is not a
pure sub-set of Eiffel.  There are differences in the syntax such as with
arrays and genericity.  All assertions use the keyword "assert" instead of 
Eiffel's keywords.  And there are other keyword changes.  Also, I have heard
that the compiler isn't very type-safe.  Personally, I feel that could have
been a purer subset of Eiffel and still met its objectives.

Go for it.  I was tempted to try it myself.  But I am too busy getting the 
Eiffel version finished.

You will save yourselves a lot of time by going with gcc or Matt's DICE.
Sadly IMOO Lattice/SAS C with human coders in mind and not as intermediate
object coders.  SAS and Aztec can not handle calls to other functions 
greater than 32K in the same object file!  Also beware of the limitations
on SAS's macros.  Also watch out for SAS's scanf()  most un-UNIX like.

    re "I think we can give up compiling anything serious with Lattice C"
    	Gee don't tell this to the developers of Amiga Dos, and any of the
    Many fine products that are available on the Amiga. I think Lattice C
    is a good implementation for a micro based computer. I rather doulbt
    that you could not write an application that can be done in any other
    language given a programmer with the right talents. I admit it looks
    like OOP is it for the future(but not yet proven in the real world)
    but to write lattice C so soon , smacks of snobbery. I also know that
    some think VI is a good editor too, so you never know. 
    								bill 

	I agree that we can discard Lattice C.  The current product is
	SAS C for the Amiga.
