Unfortunately, the world is a bit more complex, with billions lines of
existing code, customers that don't share Ada enthusiasm, not to
mention library code voids.
Don't get me wrong. I like Ada enough to be doing a project in it
right now, even thought Objective-C (it's on Mac) would have been a
better choice (libraries, libraries, libraries, compiler problems with
signals).
But let me give you a few examples:
- For a program that analyzes and transforms a C program I'd use SML
or O'Caml, because of their library code (ckit, FrontC), and pattern
mathing.
- For linux kernel development I'd use C, because otherwise I'd have
zero chances to commit my work.
- For a web e-commerce site I'd use WebObjects (now Java, but I
prefered it in Obj-C), because it will be the quickest to develop.
- Even the most Ada-centric company in the world uses tons of legacy C
code, and I don't think they will rewrite it in Ada any soon. Of
course, that code is causing them a lot of problems, but would you
call their business decision to stay with it, wrong?
- (vicious) There's also a company that is pursuing a subset of Ada,
with annotations. Are they wrong, should they switch to full Ada and
drop their annotations?
- (vicious) Would you use Ada instead of VDM or Z?
Final example, I am sincerely interested in the resolution, you may
perceive it as a challenge for an Ada zealot:
- http://state-threads.sourceforge.net/ how would you do this in Ada
(thread = task)? http://citeseer.ist.psu.edu/681845.html describes why
I would want this.
I really don't know wether to start a six months and up, high risk,
project to modify the GNAT runtime, or just use this library in C.
Regards,
Wojtek
