Well, I thought I would explain that it is a bit stalled, sadly.
I have managed to read a lot of the Barnes book on Programming in Ada 2012. Well, over half anyway. I read a lot whilst on a cruise!
It is a tad more verbose than I am used to, but overall I would have to say it does look good. The very strong typing, and the fact that all types allow value range controls, all make for much safer code. Even the multi-tasking looks interesting.
I have got to the stage that I would like to try using it, and that is where I have come unstuck, sadly.
A lot of the code I work on, and code I start from scratch even, is run on a linux environment. I have a load of our own C libraries which we use extensively, but of course linux has a lot of C libraries that are used for all sorts of things. I am not against re-working our own libraries - some of the key ones are XML manipulation and SQL front end for the standard client library. I am sure both can be done in Ada with no problem, but I am not re-working OpenSSL from scratch in Ada.
The problem is that to use these from Ada I would have to find or code interfaces or new libraries. That is going to make a huge hurdle for any code I need to write. I get the impression that there are some Ada wrappers and libraries available, but I am struggling to find them.
I mean, is there an Ada library for mysqlclient interface, or openSSL for TLS? Heck, what about something really simple to start with like popt library? There must be a good Ada XML library?! If I can find libraries or wrappers for a large list of key functions that we use regularly on linux then maybe I can start using Ada, but right now it is not looking promising.
There is one closed project we work on, and have for many years. It is a project where every library and functions is written from scratch, including the operating system. It was suggested long ago that maybe we should use Ada, and I decided against it. In hindsight maybe that was a mistake, as it would have been a perfect case where we did not rely on any external systems and could have started from scratch in Ada. That project is the FireBrick. There is even some chance we may start using some Ada modules in future... But that would have been cool - a complete operating system from scratch all based on Ada. I am kicking myself for not doing that when we started now. Sorry Cliff.
If I do make more progress, I'll let you know, but for now it is stalled.
