Dear All
I am trying to embed Ruby inside an application, a GTK widget server
which recieves ruby instructions to manage a Graphical User Interface
- see http://starynkevitch.net/Basile/guisdoc.html for more; I just
coded a Python based GTK widget server and want to port it to Ruby,
which should be easy, since my code was designed to plug into several
different scripting engines (provided they can load a script file and
interpret a C string).
I have some scoping problems; it seems that definition of functions
parsed by rb_load_file are not visible later when evaluating a C
string using rb_eval_string_protect? so I am running rb_load_file on a
file (guisdemo_rubyscript in my code) which contains
def start(welcomsg)
$stderr.printf(“start %s\n”, welcomsg)
#etc
end
and then I fo rb_eval_string_protect of a string like the following 2 lines
#request1
start(“foobar”)
and the start function is unknown
You can download my sample code (which uses ruby-gnome2-all-0.6.0 and
ruby 1.8 [1]) under http://starynkevitch.net/Basile/guis-1.2.post1.tgz
then add . to your $PATH, do a make; make a symbolic link fro ruguis
to ruguis-scripter in your path and run
./guisdemo_rubyscript -T -D -p ./guisdemo_client
Also, I would like ruby to avoid catching SIGINT; Can I do a simple
signal(SIGINT,SIG_DFL) or should I be more careful? (when sent a
SIGINT my app crashs inside Ruby).
At last, I would like to be able to set the “source file name”
(actually to a string like ‘request#123’) explicitly before calling
rb_eval_string but tb_eval_string does a rb_source_filename already
Note 1: even if ruby-gnome2-all-0.6.0 is not really for ruby-1.8 I
believe this is not my problem, since it appears without calling any
ruby-gnome2 (actually ruby-gtk2) primitives
