Well, there's always a programming language which has
more features than another. However documentation,
libraries, software-engineering tools and developer
community have also to be accounted for.
So whenever a special features is deemed necessary
but not available in the language I suggest to use
E.g. you cannot express grammars in C/Java for
parsing so usually you stick to yacc/bison/flex/cups etc.
In C++ BOOST provides capabilites to express a parser
by means of template metaprogramming but compile times
are huge. In my opinion are old fashioned parser
generators more transparent.
So it's probably not worth the trouble.
I have successfuly implemented a simple code generator
for real-time control applications in Python
which outputs C-source.
Today I'd suggest to use XML-files to describe
the problem and generate source code from it.
Source code needed for assembling the final
result could also be embedded into the XML-files.
Eclipse uses a kind of JSP to generate code
from templates. (Examples exist
for generating source code for enumerations
which are not yet supported by Java)
However it's still very primitive.
At the rapid pace at which Eclipse
is developed I am curious what way it is going to take.
