Hi All,
Hi. I was looking for someone to speak to regarding a few questions
that I had about IDL. I would be glad if someone can aswer my
question:
a) Given that we are moving towards CORBA, we would like to specify all
our interfaces ( all of them not
necessarily pertaining to client/server) in IDL. i.e., the
interfaces we specify must be capable of being used
by CORBA (which is OK) AND be available in any scripting language -
PERL, PYTHON, TCL etc. I recently
evaluated an open system tool called SWIG (Simplfied Wrapper and
Interface Generator) that allows one
to define classes or C-functions in an interface file (with ANSI
C/C++ syntax). After the SWIG generator
is run on the interface, it outputs the bindings required for a
particular target scripting language - tcl,
python, perl, etc. These interface defined classes/functions are
then directly available in the target scripting
language. For instance, if example.i contained a function "int
fact(int);" and example.c contained the
implementation for the function, running SWIG on example.i will
produce a wrapper file that, when
built together with the implementation file, makes the function
available in the target scripting language.
Thats SWIG in a nutshell and fits well with our needs.
Now, with CORBA's IDL in the picture, we are faced with defining
client/server interfaces in CORBA
specific IDL. But, we'd like to define ALL interfaces - be it
scripting languare interfaces, CORBA interfaces
- in ONE type of IDL and generate either a) Scriping language
bindings or b) CORBA client/server bindings.
This allows for consistency in interface definition even for
disparate usage of these interfaces.
My question is: Is there any support for generating Scripting
language bindings from CORBA IDL or a
translator (less preferable) that can translate from CORBA IDL to a
scripting language IDL ??
I realize that I may have to direct these questions to the
appropriate CORBA implementation Vendor.
But, I figured I would turn turn here for any suggestions!
Thanks a million!
