That's also true for the gconf librarie (that have the same purpose for
Gnome).

But we are maybe to far from Ada.Directories/Text_IO goals. 
I would prefer a new API for this purpose.

Ada 2005 presentation at Ada-Belgium event now on-line

[Dirk Craeynest]

FYI.

At the Ada-Belgium evening event earlier this year, Pascal Leroy,
Senior Software Engineer with IBM France and chairman of the ISO Ada
Rapporteur Group (ARG), gave a technical overview of the most important
improvements that are currently under consideration for inclusion in
Ada 2005.

We are pleased to announce that a copy of his presentation is now
available on-line on the Ada-Belgium web pages.

The "tree structured directories" addressed by Ada.Directories are on
their way out.  Under Windows, for instance, there's a separate directory
called the Registry (which I understand will disappear in the next major
release) and there is a (rarely used) additional directory level called
file resource forks.  It doesn't appear that Ada.Directories applies to
either of those.  It's also become rather obvious that objects need to be
"filed" in multiple ways; a single tree is inadequate.  The next version
of Windows is supposed to address this issue (searching?  relational
database?).  Ada.Directories will nicely standardize the multiple
incompatible directory operations packages of today, but that part of
Ada05 will become obsolete not long after introduction.  IMHO

For Windows probably "yes" and you always have Claw.Registry to use in
that case but for the bulk of embedded work this package will do
nicely. I'm guessing the same is true for Linux/Un*x/VMS but I don't
even have an Ada95 compiler for these.

Just a thought - I don't know the Windows Registry at all but from
what I've seen it is itself a tree structure. Could an implementation
of Ada.Directories (and I guess Ada.Text_IO) wrap the calls to
Claw.Registry? i.e. use A.D to traverse the Registry and A.T to
read/write actual values?

Note that Pascal's presentation includes a brief summary of the new
standard container library.
