Thanks Igor. I will have to explore this option when I get time. It
seems a lot to learn.
I have downloaded the videos and slides. I also downloaded Bruce
Eckel's "Thinking in C++" books.
And also thanks Stéphane for the reference the Greenberg pdf.

When you say make a VM plugin are talking about not using NB?
I am not quite sure what you are talking about doing. I would like to
understand better.
the VM plugin is a module written in C, which provides own set of primitives,
which you can use in a language. There's a lot of plugins for VM existing.
I think you can find some sources if you google for 'squeak plugin',
also i did some slides for smalltalk summer school
(http://rmod.lille.inria.fr/web/pier/blog/2011-01-23).

Regarding the wrapper, is that a wrapper around the DLL?
not necessary DLL, but in most cases, yes.
Any education on how to do what you are talking about would be greatly
appreciated. Enough to get me going in the right direction with links or
something.
I have not read the documentation regarding writing a C++ app yet, as I do
not know C++.
I'll have to see what I need to do to learn C++. :)
I agree that this would be the most efficient way with regards to the
application. If it is within reason educationally close in time spent to
Clojure time educationally, I would definitely consider this direction. I
realize anything like this is just a guess and estimate as to my ability to
learn either Clojure or C++.
Thanks for the encouragement and education.

Hi, Jimmie
i took a brief look at the library and interfaces it provides.
To my opinion, if i would need to use it, i'd rather make a VM plugin for
it.
First, since its C++, and you need to write wrapper, making wrapper as
a VM plugin
is better than just another C library which you need to link via FFI.
Connecting to java: yes its possible, but then it means that you will
have a java runtime
in your process, which is much heavyweight..
Just want to say, that if efficiency is issue, i would go for VM plugin.
But since you are not me, the price of learning C++/Java may be too
high, and i understand why
you looking for alternatives. But in your place i would advise you to
learn C++ basics. It will open a door
to other languages of C family (because of similar syntax & rules).
You may/will need it one day anyways :)

Clojure->java -> c++
i would just write C++ code
The API is either Java or C++ or .NET.
I agree that no sane person would go Clojure->Java->C++ :)
Clojure would provide the option of interfacing natively the Java API,
without having to write Java. But then I am left developing in Clojure,
unless I decide to serve to Pharo via http/websockets.
As I do not currently know Java or Clojure or C++, it currently seemed
like
learning Clojure as the optimal path of least resistance.
That is with a belief that I could learn Clojure better, easier, faster
than
C++, or at least a sufficient subset of C++ to work with NB.
If I could learn a subset of C++ sufficient to interface NB/Pharo with
ForexConnect, then I would be happy to do so.

Especially if I had a roadmap to help provide me with said proficiency
and
that I could do so in equal or less time than spending with Clojure.
It is a pragmatic decision. Long term I want to spend my time in Pharo
and
not in Clojure or C++, which is why I am attempting what at the moment
requires the least effort or at least by best guess appears to be so.
I have found nothing that I can program and interactively explore and
experiment with better that Smalltalk/Pharo. It is most definitely my
preference to do so. And I so greatly appreciate all of the efforts being
made to make it an option more of the time.
JavaConnect that Stéphane mentioned looks very interesting.
I really appreciate your input into this. I can gauge the effort to learn
Clojure and I find it reasonable. C++ seems from the outside to be more
daunting. I could be wrong. Let me know if you have a different opinion.
Thanks.
Jimmie
