GNATBench 2.1.0 (free) and file/procedure naming case

GNATBench 2.1.0 (free) and file/procedure naming case

[John McCabe]

Hi

I've just got a new PC so I've installed GNAT 2008. I like Eclipse so
I've installed that with GNATBench.

Now, some time last year I had a problem with GNATBench in that, when
I tried to build a project, it came up with an odd message about not
being able to execute the command "<some nonsense string>" etc. That
still happens, so I've sorted it the same way I did back then which is
to make sure I have a version of make called make.exe in my path.

However the latest thing I have is that GNATBench doesn't appear to
maintain the casing I use for files/folders and procedure. For
example, I put in TestAdaProj as the project name and MyMain as the
main procedure and it creates folders and files called testadaproj and
mymain.adb respectively. Is there something I've done wrong here that
anyone can think of.

This is a newer version of GNATBench than I used before, yet it still
seems to have all sorts of issues (possibly trivial, but very
annoying).

Has anyone got any idea what's happening with Hibachi? That seems to
have gone completely dead.

Thanks for your help.
John

Try putting the following in your GPR file:

package Naming is
   for Casing use "mixedcase";  --  otherwise, default is "lowercase"
end Naming;

This is described in the GNAT User's Guide (section 11.11, Naming
Schemes).

I haven't tried this myself since I use GNAT's default naming
conventions.  Regarding GPR files, I've found it better to edit them
manually (in Eclipse) rather than use the GNATbench (or GPS) project
properties editor.

I lurk on the Hibachi mailing list. List traffic dropped to near zero
long ago, so it is effectively dead. I don't miss it. GNATbench is
much better if you are using GNAT as your compiler.

For what it's worth, chances are that may work fine, but this issue
happens when creating a project from Eclipse. If I then set that value
and rename all my files and folders to what I wanted in the first
place, the Ada Project Explorer in Eclipse gets totally lost.

It's so phenomenally frustrating; I can't see that I'm doing anything
particularly odd or unusual, yet every time I try to use GNATBench it
just seems to put all sorts of obstacles in my way instead of just
working!

Maybe it's just me!

Oh dear. Seemed like such a good idea.

You're using the paid for version though aren't you? Perhaps that just
works better!

Maybe you are confused between unit names and file names. In the Ada
world, we care about units (the content), not so much about files (the
container).

In the case of Gnat, it has precise rules for matching unit names with
file names, and it requires all *file* names to be lowercase. This is
because case is not significant in Ada; there must be some convention to
make sure that BLAH Blah and bLaH all fetch the same file - here blah.ads.

In short: name your units as you please, and let the environment choose
the appropriate file name for you.

I don't think this can be right. See the GNAT Project Manager page on
*file* naming:
http://gcc.gnu.org/onlinedocs/gcc-4.1.0/gnat_ugn_unw/Naming-Schemes.html#Naming-Schemes

Personally, though, I'd go with the default: lower-case filenames,
mixed-case Ada names (and, John, I think you'd have a better chance of
getting GNATbench to use mixed case in some predictable way if you
Used_Underscores ratherThanRunningThingsTogether)

Yes, of course, you can change the convention from the default one, but
I think the problem the OP had is that *some* files had names that did
not follow the default (or any other) convention.

So my advice can become: choose any convention you like for file names,
but once you have it, let the environment deal with file names. And by
all means, be consistent.

Agreed

I haven't used GNATBench, but part of the problem may be that the GNAT tools 
on Windows convert file names to lowercase.  Long ago, using different cases 
(i.e. on command line calls) would cause internal GNAT errors.  The same 
issue did not impact Linux (etc).

With the standard GNAT tools, the files they create are lowercase, but they 
will find files of any case.  I don't know if if manually renaming the files 
would work here.
