Seeking some of that old-time Smalltalk religion

John Lam

3/22/2006 3:59:00 PM

I know there are some Smalltalk folks who hang out here, so I'd like to pose
perhaps a fairly ignorant question:

How far away is irb from a Smalltalk development environment?

Put another way, what must need to be done to get to a Smalltalk development
environment? Will being able to load / save image files get me closer (have
folks done this by serializing the ObjectSpace tree to disk already)? Or am
I just going to have to experience it for myself to get the gestalt of
Smalltalk IDEs?

Thanks for any & all insight ...

<disclaimer>Not being a Smalltalk guy myself...</disclaimer>

I'd guess that it's quite a long way from IRB to a modern Smalltalk IDE:
IRB doesn't have a graphical UI for example. But I've heard there are
quite a number of decent Ruby IDE's out there.

Note also, that marshaling object graphs doesn't help here because that
doesn't capture methods. So the tool would have to keep track of
defined variables and methods and store them somehow.

Kind regards

I've been working on a Self/Squeak type interface environment for Ruby:
http://www.mike-austin.com/interface-design/Ruby-I...

I think Self and Squeak are pioneers in live design, but I find them a little
over-complex. Ruby-Inertia is being designed from scratch using SDL, OpenGL
and FreeType. I've written prototypes of it in C++, Io and Dylan also. So
far, Ruby seems to be the easiest (I wonder why? :) Nothing to release yet, it
needs a little more work.

The short answer is light years away. Go over to
http://www.objec... and download the free Community Edition of
Dolphin and see for yourself. It makes all other IDE's look antiquated.

Whoops - that's right. Is it possible to persist Ruby's AST as well as the
live object graph? I guess I'm going to have to spend some time digging into
the sources to see how the AST hangs together and whether that would even
make any sense.

Thanks

ParseTree can be used with Ruby2Ruby to persist some of the AST.
There are limitations though.

I forgot about ParseTree - thanks for making it!
