they did with IronPython; creating a tokenizer, a parser and an AST. I would
also envisage moving away from an image based model to a file based model. I’m
sure there are many out there who see this a blasphemy but I always saw this as
an impediment to Smalltalk being taken up by the general programming
population, even as far back as Smalltalk /V I saw this problem with me fellow

sooner but I am fighting off a cold. <br>

Gary I definitely have time to work on this project starting next week. <br>
<br>
I think agree with Steve when he says: "The easiest way to get this up and
running would probably be to have a look at SmaCC and #Smalltalk"<br>
<br>
Why reinvent the wheel when there is a working model to create a baseline for
an IronSmalltalk implementation. I have been in contact with one of the authors
of #Smalltalk and he was great about answering a few questions. Tomorrow
I am going to take another look at the #Smaltalk code and implementation. <br>
<br>
I'm open to any other Ideas that you and Steve ma have.<br>

<p class=MsoNormal>I took a look at the latest snapshots of the IronRuby code
from svn://<a href="http://rubyforge.org/var/svn/ironruby" target="_blank">rubyforge.org/var/svn/ironruby</a>
but I wasn't able to build it this time.<br>
<br>
There's an in-depth article about the DLR and IronPython at <a
href="http://msdn.microsoft.com/en-us/magazine/cc163344.aspx" target="_blank">http://msdn.microsoft.com/en-us/magazine/cc163344.aspx</a>.
Python builds nicely and you can execute sample scripts but the code seems to
have been refactored quite a bit since then and the tutorial is now quite hard
to follow. The source is at <a href="http://www.codeplex.com/IronPython"
target="_blank">http://www.codeplex.com/IronPython</a> - you will need to
install TortoiseSVN and a thing called SvnBridge to get the latest code from
Microsoft. The license is BSD-compatible.<br>
<br>
Both these projects and the underlying DLR seem to assume that dynamic
languages are scripting languages. I think that this is not entirely consistent
with the way Smalltalk works, but I suppose there's no reason you couldn't
build a Smalltalk compiler that works as a scripting language. You would need
to do something like this to bootstrap the environment anyhow.<br>
<br>
One of the things I like about Smalltalk is that all the tools (e.g.
Transcript, Workspace, Code Browsers and Debuggers) are all written in
Smalltalk (it's tortoises all the way down!). I think it would be interesting
to implement these components in a library that could be loaded into an
application domain for development purposes. I don't think that using vim or
emacs to develop Smalltalk code would be particularly productive and some
native tools would provide a more incremental development environment than
Visual Studio.<br>
<br>
To get started on a project like this I guess you would need to have a look at
building a Smalltalk Language Provider. The easiest way to get this up and
running would probably be to have a look at SmaCC and #Smalltalk - I think the
parsing and code generation would be much the same whether you're targeting the
CLR or the DLR.<br>
<br>
A key milestone might be to have something that's self hosting. If the DLR was
packaged as a DLL instead of a project dependency, then you could write the
compiler in Smalltalk instead of C#.<br>
<br>
The code is here <a href="http://www.refactory.com/Software/SharpSmalltalk/"
target="_blank">http://www.refactory.com/Software/SharpSmalltalk/</a> - I think
it's already self-hosting on the CLR. I believe that John Brant discussed some
of the conceptual differences between Smalltalk and .NET on comp.lang.smalltalk
a few years ago.<br>

<p class=MsoNormal style='margin-bottom:12.0pt'>Could be interesting. I'm not
using Windows much anymore but my PC should be here in a couple of weeks. I
managed to build IronRuby from source at one point. Based on what I've read on
various blogs it sounds like it should be possible to extract the DLR from
that, but maybe your contacts in MS can point us at a DLR-specific svn
repository ;-)<br>
<br>
I suggest we set up a google or yahoo group to drive into the details. Anyone
who's interested in helping or lurking can follow along there.<br>

talking to the dynamic languages team out there and got really fired up about

so, to date, it has gone nowhere. However, coincidentally, I am now in a
position to start working on it again. I'm in the process of getting my head
around the DLR and the ANSI Smalltalk spec so, as yet, no actual code has been
written, but I'm going to be getting to that soon (for some definition of soon
<grin>). As for do I need help? Hell yeah! LOL, are you (or anybody else)

the creating an IronSmalltalk implementation. Is someone currently working on
IronSmalltalk ? If so do they need any help?<br>
