Asis.Ada_Environments.Associate (..., Parameters => ...);

Asis.Ada_Environments.Associate (..., Parameters => ...);

[Hibou57 (Yannick Duchêne)]

Query to ASIS users :

The “ Asis Asis.Ada_Environments ” specification file does not
document the “ Parameters ” argument. Searching the web about it, I've
found a documentation called “ ASIS for GNAT ”, here :
http://www.gnu-darwin.org/www001/src/ports/devel/asis/work/asis-3.15p-src/documentation/asis_rm.txt

This document list some parameters in the “ § Parameters of
Asis.Ada_Environments.Associate Procedure ”

I just wonder if these are standard parameter or ASIS-for-GNAT
specific parameters.

Sure I'm not the only one interested in such a question :p

Its talking about tree files, which may seems to be GNAT specific,
while other implementations may have similar concept.

No need to search the web; that file is included in the GNAT ASIS
installation, in html, info, and pdf; gnat/share/doc/asis/*

asis_rm.txt 3.1 says they are implementation specific.

It appears the ASIS standard document is not freely available, so it's
hard to be sure.

I do not have a desktop search engine, this may be why I did not find
it there.
I've check it is, indeed.

As the specification file does not give any reference, I suppose too.

May be another GNAT specific stuff : I could not get ride of ASIS
warning messages while I open an ASIS context. No standard ASIS
methods seems to provide abilities to manage this. These messages are
written on an error stream, but I could not redirected these with
either Ada.Text_IO.Set_Error or Ada.Wide_Text_IO.Set_Error.

That's right. I can't give you a copy of the Standard unless you're actively 
involved in working on it. We did make the "Committee Draft" version 
available through the SIGAda working group - but it has lots of errors that 
are being corrected.

In any case, I went and read the standard for 
Asis.Ada_Environments.Associate, and I don't see any description at all of 
what the parameters mean. However, the description of type Context gives a 
bit more idea of what is meant. But there is nothing in the standard about 
the contents of these parameters. Moreover, there is this sentence: "The 
concrete mechanism of this association is implementation-specific." You're 
welcome to guess at exactly what this means (there is a lot of such text in 
the Asis standard!)

Anyway, I would expect the actual values used for Name and Parameters in 
Associate to be completely defined by the implementation.
