I've recently begun my foray into Concurrent Programming using Ada,
Lucid, and Erlang. Considering playing with Occam also.
What Ada libraries, that are in common use, would you recommend are best
suited to Concurrent programming? I intend to keep the "core" of my
applications well seperated from any dependencies on the host platform.
Nonetheless I'm aware of the fact that different libraries are better
suited to different platforms when concurrency is involved.
I'm also investigating ways to attach "command" tools to my Ada apps.
i.e. Like a scripting language, an SQL console, a Prolog or Lisp console,
etc... How have you guys done this in the past?
Any advice would be greatly appreciated.

I maintain an Ada component library (fully platform-independent) which
provides some lock-free containers as well as some blocking synchronization
primitives like mutexes and events. It also provides plain containers.

The library also provides string processing and parsing tools, which can be
used for building interpreters. As an example of use an Ada 95 parser is
provided.

Ada is a building-block language. Its language features operate
orthogonally, so you can mix and match as you see fit.
The easiest thing is to use the (sequential) container library already
included in the language, and then use whatever other building blocks
(e.g. protected objects) you need to satisfy your concurrency needs.
If you describe your specific need, we can probably show you what to
do.

Right now I'm building a library for an Internet Protocol I'm designing
called "Ferret". Think of it like a new and modernised Gopher. It uses
DAP services instead of the Filesystem Hierarchy used by Gopher. I'm
using it to tie together multiple network data sources (Web, Ftp,
etc...) into a single coherent whole, that can be queried and searched
using your preferred command language (Rexx, Perl, Lisp, SQL, Prolog,
etc...)
This is a pretty hefty task, but once the core libraries are in place,
the rest should be trivial.
I plan to use PolyOrb as an optional middleware between nodes on the
local Ferret network.
Eventually I'll bring in some sort of document markup tool. Probably
based on RuleML. The only catch is that Ferret documents are prohibited
from containing any Presentation information. Period.
The preliminary research work has already been done with the old Gopher
service.
The World Wide Web is bloated and top heavy.
And quite frankly, I'm sick of sifting through websites and google
rankings. At least I can catalog the information across my local network
in a more sane fashion. And theres plenty of information to manage here.
Dont worry, I'll let you know when my grand plan hits the ground in a
glorious fireball. Heh.

The PragmAda Reusable Components contain a number of protected data structures
and other concurrency-related components such as task decouplers and safe
semaphores.
http://pragmada.home.mchsi.com/
Note that the PragmARCs are Ada 95 and use private types in ways that are
prohibited by the current standard.

I'm curious about these now-prohibited ways. If you have the time to give some
example it would be great.
Thanks!
