Hello,

Could anybody tell me if there is a library or kind of program which tells
me the structure of a disk? I mean if there is a way to show the structure
of a folder (with subfolders and files).

Thanks in advance

  Could you be more specific about what you want?  Under DOS or Windows
command line, you can use "tree foldername" to display the subfolders.
I have a program that displays the tree showing sizes of files & folders.
There are libraries that let your program step through a directory
and its subdirectories.  There are also platforms which don't have folders,
or even disks!

Hi, 

If you are using Gnat, look at Gnat.Directory_Operations.

This package provides the necessary primitives to traverse
a directory and change directories from within code.

If you need to detect that a file within the directory is
a sub-directory, use the function "Is_Directory" from
Gnat.Os_Lib.

For more detailed file information bind to the OS code of
your choice. On linux for example, I bound to all the 
necessary functions to be able to "stat" from within an Ada 
procedure which enables me to ignore sockets etc.


Pseudo-code :

GDOP renames Gnat.Directory_Operations;

Store Directory name of interest in a queue

loop

   Is the directory name queue empty ?
   YES : Exit loop
   NO  : 
       Get the Directory name and GDOP.Open it.

       while GDOP.Read (... opened directory) /= no more files

           Do what you want with the file name.

           Is the file name a directory ?
           YES : Add the name to the directory name queue.
           NO  : No Action

       end loop;

       GDOP.Close ( ... opened directory).       

end loop;

It is just under DOS. I need to show folders, files and sizes.

Thans in advance

As I haven't clear enought I must point that I need to make a program in ADA
which shows trees, files, sizes, etc. If anybody knows a library in ADA
please tell me!!!

Thanks in advance

It is not for homework, I'm just writting a program for fun. If you want a
certify I can send you a declaration signed by me and my lawyer :-)

See You Soon!

  Look at the recent thread on "Directory listings and path names" for
pointers to the proposed standard, and to several currently available
libraries.

Aaah... in that case there are two tools using GNAT.* resources
- see htmltree and html_dir in gnatpaqs.zip, URL below:

Happy programming!
