Um, this is called a compiler.

I think you meant the opposite:

"anyone know a tool that can retreive Ada 95 source from a object code
?"

The answer to that is no.

No, (based on the subject line given, I believe) he means "is there a reverse
engineering tool to be recommended that can generate object diagrams etc. from
Ada source code?"

I don't recommend any because I haven't used any in a long time.  But in the
other direction, I like UMLStudio (www.pragsoft.com).

www.artinsansw.com have an Ada->UML tool going through beta-testing just
now I believe. This is part of their "Real-time Studio Pro". This isn't
intended for
home/student/hobbiest use though.

www.ilogix.com are going to have one (by the end of the year?). Again, this
is
probably not going to be available unless you have deep pockets.

I like Pat's UMLStudio for home use too ;-)

Ah. Yes, that is one definition of "reverse engineering". I was using
the older definition. I guess I'm showing my age?

Cadre Teamwork and Rational Rose could both do that.
I'm not impressed with the results of either.

Rose output is better than doing the whole thing
by hand, but you'll still do MOST of it by hand.

Teamwork was so bad, it would be BETTER to start
from scratch, but that was more than eight years
ago.  By now, they've probably either fixed it
or dropped it.

What is about ASIS? ASIS provides exaclty what you are

Ahh yes, the saga of Teamwork.

I understand it was originally developed at GE Aerospace (my first
employer), and then sold to Cadre. Cadre later sold it to Cayenne, who
renamed it "ObjectTeam".

In the last 2 years, the following happened: Cayenne then sold it to
Sterling, who already had a CASE tool called COOL:JEX. They apparently
liked the name better than the product, as they dropped their COOL:JEX
codebase and renamed ObjectTeam as COOL:JEX. Then Sterling got bought
out by Computer Associates and briefly renamed it to COOL:Teamwork
before selling it to Telelogic a couple of months later. Telelogic
renamed it "Tau", then later "Tau UML Suite"


I used Teamwork back in the pre-UML days (1989), but we never tried
code generation or reverse engineers. I used the ObjectTeam (not
realizing it was the same product), and can vouch that its
reverse-engineering still sucked. For instance, it wanted to make each
enumeration type ID a class instance. %-(  I haven't used any of its
later incarnations, so I can't vouch for them.

Teamwork's reverse engineering algorithm in 1990
generated Buhr diagrams from Ada, with an algorithm like:

For each subprogram or task in the input,
   generate a new separate diagram containing one subprogram
          and an invocation arrow.
   put the name of the subprogram in the box
   put the parameters on the invocation.
end

So to make them usable, you go through all the diagrams
or source to identify all the packages (source is easier).
Then you manually create each package.  Then you create
all the visible subprograms/tasks in each package.  You
can cut and paste names and parameters from the revenged*
diagrams, or from source.  Guess which is easier!  :-)
Once you go through this step to make the model useful
for anything at all, you have to maintain it in that format,
because to reveng it again means doing all this over!

As for code generation:  It generated ONLY the skeleton,
i.e., only that which was obvious from the diagrams:
declaration, parameters, begin, exception, end.  It inserted
special comments to divide each compilation unit into
NINE sections.  Each section was stored in a separate
file, which so-called "code generation" pasted back
together.  These sections had to be maintained by hand,
but to syntax check or use any other tools, you had to
run the generator.  If you ever edit a compilable file,
see above comment about "reveng it again"


*the reverse engineering tool was called reveng - appropriate!

StP by Aonix has Reverse Engineering module. I have never used the
Reverse Engineering module before, but I guess it can provide what you
want.
