[Announcement] Ada0Y.Directories - alpha release

[Announcement] Ada0Y.Directories - alpha release

[Martin Dowie]

Under the premise of 'release early, release often' I'm announcing an alpha
release of "Ada0Y.Directories". This is an implementation of AI-248
(http://www.ada-auth.org/cgi-bin/cvsweb.cgi/AIs/AI-00248.TXT). Also included
are AdaBrowse generated html pages containing the AI text as comments to
each subprogram and some test programs.

It isn't 100% complete but it can currently:
 - set/get current directory
 - create/destroy directories
 - create paths
 - search for files/directories (including wildcards)

The URL is:
http://www.martin.dowie.btinternet.co.uk/

It has been implemented and tested on WinNT/WinXP using GNAT 3.15p.

If you can confirm other configurations please send me details via the
'feedback' links and I'll include a table.

If you find any bugs please also send 'feedback'.

Great! (Noticed that the tests where missing. No tests.zip file it says)

"The exception Use_Error is propagated if
    -- the external environment does not support the creation of a directory
    -- with the given name (in the absence of Name_Error) and form. "

hi;

Man of the functions in that package raise the above exception.

Does the standard allow the user to obtain a specific error as to why
the exception occured? In practice, one would want to know WHY the error
occured, not just that AN error occured. 

For example, in Unix, one can read the error number to find more information
about why a function failed (returned -1 for example).  Is it possible to
get this info from the detailed of the exception itself here with Ada somehow?

Depends...There is no errno or multi-returnvalue but usually the idea here
is to use different exceptions for cases that should
be processed differently and provide the extra "programmer info" type stuff
from something like Ada.Exceptions.Exception_Message

I'll look into providing more detailed error reasons where possible, though
I may consentrate on just getting functionality in first - I only have about
15 minutes a day to devote to this :-)

spend you 15 min today on reading:

http://adacl.sourceforge.net/html/______Include__AdaCL-OS-Command__adb.htm

look for  "procedure Start".

Actualy the LGPL:

--  modify it under the terms of the GNU Library General Public

--  version 2 of the License, or (at your option) any later version.

But there is no pragma for it.

I see, but check a bit about that license because I remembered some
discussions that it was not so nice.

Ada0Y.Directories - updated

[Martin Dowie]

I've uploaded a new version of Ada0Y.Directories at:

http://www.martin.dowie.btinternet.co.uk/

New features in this version are:
  o Copy and rename files
  o Added support for Simple, Base and Full Names
  o Added support for file extensions
  o Added support for modification time*
  o Simple directory name simplification
  o Added exception messages
  o Updated the tests
  o Added more info from the AI as comments to the package spec
  o Added more AdaBrowse tags
  o Added "pragma License" information
  o Created HTML using GNATHTML

* On Win32 this is GMT and not the value seen in Explorer.

Still not 100% compliant but probably good enough for applications.

Thanks to those who have already sent feedback, the more the
better! I'm particularly interested to here from people using
something of than WinNT/WinXP.

Martin
