Un-crunching

Un-crunching

[Phaedrus]

On a similar note to Martin's un-separating note, does anybody know how to
"un-crunch"
filenames?  I've got a LOT of files whose names have been crunched with
gnatkr down
to 8+3 format, and now Gnat isn't happy with the shortened names.  Is there
a utility to parse
the packages and give them a standard filename?  I had hoped that a
parameter with gnatkr
would have been able to undo it, but that doesn't seem to be the case.
Sure, I could write a utility,
but I'd rather not reinvent the wheel.  Or maybe I'm missing a Gnat
parameter that would make it
happier with the crunched names?  I'd really rather not have to rename all
of these files!

TIA,
Phaedrus

I once tried to "un-crunch", for documentation and easy reference, gnats
own libraries but I have never been successful.

Read the manual, tried various commandline options and it didn't work. So
could you elaborate on your answer, please. I would realy be gratefull. 

With regards.

you'll have to give more information than that.

1) Describe your files, giving the file name and the Ada name of the
compilation unit it contains

2) show the command you executed

3) show what the result was.

otherwise we are just shooting in the dark.

Yes, I've seen this too and never found a (quick) work around.

Works perfectly well as per documentation with any other files, in
my experience.

This is rather sad. Finding the actual specification for a package
"grep"ing throu all the sources is that terefic.

Re: Un-crunching

"Reading between the lines," it seems what you want to do is to
"browse" source files from the standard Ada library.

GNAT provides two easy and effective ways to do this, viz.:

  1.  Use the emacs editor with ada-mode

  2.  Use gnathtml (a perl script) to generate navigable html
       pages showing the source code.

Both of these methods provide color syntax highlighting, and
navigation from a reference to an identifier to its declaration.

Emacs also provides a clickable list of references to an identifier.

I use emacs for developing, and provide html files for projects at
certain milestones in a public directory, so the files can be
browsed by others.

The perl script has a switch that specifies whether you want to
include the standard library in the generated html.

Or  3.  Get AdaBrowse (an executable) and use that to generate
        navigable html. AdaBrowse is GPL'ed, executables pre-built
        for Win NT/2k/XP; for Linux, re-build from the sources.

Oops, the correct URL is of course

Sorry for the typo.

From what I recall, GnatChop has always had a 'special exception' to
always krunch Ada.*, System.*, Gnat.*, etc.  This made some sense back
when I was using GNAT on DOS, since it meant GNAT library files would
always have the same names.  I don't know why it's still there (DOS
doesn't seem all that big a market for GNAT these days, and I don't
know if there are any other ports with the same filename limitation).

I think I recall Robert Dewar once explaining that this was part of
the "rules" GnatChop uses, but if it happened that was long long ago.

  Do a global replace of "Ada" by "Qdq", do gnatchop, global replace
in reverse?  But, as pointed out, you probably don't really want
unkrunching, but rather some sort of source browser tool.

I have tried several but I can not get to grip with any of the classic

While gnathtml does provide some nice output it still does not solve the
main problem: these cryptic, outdated, unreadable and plain horrible dos
style filenames.

Thats because the table of content is based on filenames and not on package
names.

Well, not your fault I guess and gnathtml is a good tip after all.

Ah! As others have said, gnatchop has a special exception for Ada.*,
System.*, and (maybe?) Gnat.* packages.

To fix this, get the source for gnatchop, delete the special
exception, and recompile.

One of these days, I may do that myself. For now, Emacs Ada-mode knows
how to browse to those files when needed, so I'm happy.
