I am in search for a visual programming environment for the following
languages:

1. Pascal (www.freepascal.org)
2. ML (www.smlnj.org)
3. Prolog (www.swi-prolog.org)
4. Smalltalk - GNU (www.smalltalk.org/versions.html)

Not necessarily one program for all 4 (although that would by nice);
you can provide 4 seperate programs. The programing environment must
follow specifications / versions of the compilers on the respective
websites listed above.

By visual programming environment, I am referring to something like
Microsoft Visual C++ 6.0 in that you have a programming pane with
syntax coloring, files pane, and debugging pane (and of course the
debugging abilities such as being able to step through the program
execution etc).

I am running Microsoft Windows XP SP1. The programs provided should be
free or nearly free, and should be Windows based.

Request for Question Clarification by maniac-ga on 10 Sep 2003 17:20 PDT

Hello Jgortner,

Would you consider using Emacs - which can...
 - support all four languages requested (plus many more)
 - source displayed with keyword and comment highlighting and/or
coloring
 - also has a variety of "electric modes" where it will align text,
show balancing () or {} and a number of other syntax directed
operations
 - has a "speedbar" which operates as a file selection tool. Emacs
also can "edit" a directory and open files directly from the
directory.
 - debugging is integrated with a variety of debuggers (at a minimum -
can run the debugger within the window, but for some languages will
also track with the source code).
 - and allows you to manage this from a single window or multiple
windows [your choice]
 - is customizable to support a variety of capabilities

It IS free software, however it may not appear as polished as you
would expect. There is an extensive FAQ at
  http://www.gnu.org/software/emacs/windows/ntemacs.html
Please review this and if this is acceptable - let me know so I can
prepare a proper answer. If not, please say a little more about what
features you must have / not have so I can find a proper set of tools.

Clarification of Question by jgortner-ga on 10 Sep 2003 23:41 PDT

Thank you very much for the response! Here are my feelings...

I used emacs a while back and remember it being quite raw. However, I
do know my list of necessary languages are old and I am sure there are
not many options. I would prefer a more user friendly environment
(like Borland Jbuilder or something), but if your search is
unsucessfull please let me know.

Also, here is a list of specific reasons I am looking for a visual
programming environment which should help you more adaquatly
understand what I am looking for:

-- multiple panes for programming, debugging, program output, and
project files
-- syntax coloring and automatic formatting / indentation
-- debugging capabilities which include walking through execution
while viewing both program output and program variables
-- adaquate compiler errors (tell me which line number, file, etc.)
-- ability to have open / edit multiple files
-- ability for "projects", organization for programs with multiple
files


OPTIONAL but would like
-- integrated help
-- ability to change editor colors (font and background)

I am somewhat flexible, but would like to know of any compromises I
must make before deciding. Thanks so much for your time! It's greatly
appriciate and should help me do well in my comparative languages
class.
