I am not sure if this is the right list for this kind of question.
I am considering embedding guile in an application, and have some
questions about doing this. The application will be using GTK.
I see three possible ways of doing this one of which may not be a
way at all:
1. Using GTK's event loop for control and processing guile events
either one at a time or a glob.
2. Using Guile's event loop (or whatever it is referred to) and
processing GTK events either one at a time or a glob.
3. Run Guile in a seperate thread.
I am pretty sure 2 is possible and 1 is not. I do not see a way in Guile
to control the flow of the interpreter. GTK does provide such a mechanism
so 2 should be possible. 3 seems possible but may increase the complexity
of the design.
The application will have certain drawing primitives which I wish to be
user extendable using Guile, and possibly also extending the UI as well.
What would be ideal is to have my own event loop something like:
while (1)
{
/* Process GTK events */
gtk_main_iteration ();
/* Process guile events */
gh_process_events ();
}
Is this possible or does anybody have any suggestions for doing this?
Thanks for any help.

Do you know about guile-gtk?

Guile does not have events just like C does not have events. You
don't need to do something special to 'keep Guile running'. However,
you need to take the same care in your Scheme programs to keep Gtk
running as you need to in C code.

Guile-gtk offers this option...

and also this. Guile-gtk can run the Gtk event loop in a separate
Guile thread.
Does this help?

No. I will have to look into it. It looks promising.
