I know the subject line is quite a mouthful! Sorry about that.
I’ve managed to embed a Ruby interpreter into my application and I can
call Ruby functions from the code in my application. It works fine and
returns results to me as expected. I can also ask it to run a script
for me.
Now, I’d like to get it to do some automation for me. My project starts
up, loads a few things, sets a few properties, etc. I’d like to be able
to automate this using the embedded interpreter. I expect the code in
the script may be as simple as:
set_default_color(0x00ff0000)
set_screen_size(800,600)
…and so on.
Now, as I understand it, in my application, I need to these C functions
in it:
VALUE set_default_color (VALUE color)
VALUE set_screen_size (VALUE w, VALUE h)
… and so on.
I just don’t know what to do next! I’m not even sure what I should
search for - should I like at how to create an extension? Does that
mean that I need to get into the mkmf, etc. and compile some things for
it to work (I shudder because my primary environment is Borland C++
Builder/ Turbo C++ and I had enough worries getting the interpreter to
be compiled in).
To use the script from the embedded interpreter, can I just ask it to
run the script?
I’m sorry if some of the questions/ explanations are a bit vague. Any
help/ direction is greatly appreciated.
does have the necessary to help me connect the dots. I was staring at
the example for quite a while before I sent the email out, but I guess I
just didn’t see it.

I don’t see anything wrong in the subject line.

Grats.

Well, the Pickaxe has a chapter on this stuff.
There also is rb_define_module_function(VALUE model, char *name,
VALUE(*func)(), int argc) and rb_define_singleton_method taking the same
arguments. I never tried any of these, and don’t quit know how to tell a
module function from a singleton function from a system function. (The
last one is in Kernel, the other two can be in any module or class.)

Haha, thanks for that!

Ya, actually wisdom strikes soon after one requests for help. I did
find the necessary stuff in one of the links that I had been staring at
for a while… and after that, it was easy enough to connect up the dots
to get things moving.
Thanks for the example. I followed the procedure for defining a module
and then creating the functions within it. Not sure if I eventually
want it to be that way but I know enough now to keep exploring.

mfg, simon … l
Might I ask what “mfg” stands for?
Mit freundlichen Grüßen (with friendly greetings – more or less like
“Best wishes”).
It was just a friendly question piggy-backed to my response to the
original reply. But, I understand what you mean. I could have avoided
the responses that followed.
By the way, thanks for the link - it’s quite neat!
Mfg,
Mohit.
