See Debian Reference on Debian site which should be displaying such

 area number of packages
 main38064

This is for upcoming wheezy :)

 I have an idea of roughly 20,000 in my head, but cannot remember why I think 
 it and it may be vastly out.  Nor into which of my two categories the figure

 excluding non-Debian sources) is:
 
 $ aptitude search '~A^stable~ODebian' | wc -l

 My numbers are still a bit bigger than the count from the Packages file, 
 but don't know why (it doesn't seem to be due to virtual packages).

I think your number is about right for squeeze.

Debian FAQ package number is not scripted.  So needs to file bug report
to package.

 Because ~s (?section()) doesn't correspond to main/contrib/non-free.

 In theory true, but in practice:

 $ apt-cache show nvidia-glx | grep ^Section
 Section: non-free/x11

 This means a search for contrib or non-free with ~s will succeed, but
 not for for main, since packages in main don't advertise the archive
 component in the Section field.

Thanks for the correction. Although I consider this a cheat or a bonus
depending on the point of view, it's a practical one because AFAIR
dpkg-query doesn't have a ${Archive} option.

Maybe from Synaptic? It lists a total of packages it can fetch in the

testing and unstable and Synaptic reports 43132 packages is available.

But the question might be, what's a package, and what's a libary? Just

Edit your /etc/apt/sources.list to have only the line

Then

   apt-get update

and look at the output.

Add contrib to the line above and repeat, Do the same with main added.

Source or binary packages? If you consider source packages then Open 
Office counts as one package, but if you consider binary packages it 
will be a lot more (especially since Debian Maintainers have the good 
habit of splitting big packages to accommodate various use cases.
 
 I have an idea of roughly 20,000 in my head, but cannot remember why I think

http://www.debian.org/intro/about mentions over 29000. aptitude gets 
me 43004 binary packages for squeeze (i386, of which contrib 271 and 
non-free 583) so those should be source packages:

$ aptitude search ~Astable | wc -l
43004
$ aptitude search ~Astable~scontrib | wc -l
271
$ aptitude search ~Astable~snon-free | wc -l
583

(~s works because the archive component is part of the section name for 
packages not in main)

Kind regards,
Andrei

Thanks!  That is exactly what I wanted to know.  I have not got Synaptic 
installed, since I prefer the command line for package management.  Perhaps 
the information is also available in aptitude's n-curses interface.  I didn't 
think to look. :-(  There is also probably a command line way to do it in 
either apt-get or aptitude.  I just don't know it. :-(

 But the question might be, what's a package, and what's a libary? Just
 my thoughts though.

D'oh!  I had thought (or rather, clearly not thought) that for present 
purposes that wasn't all that significant.  Though come to think of it, that 
may be why I had the figure of 20,000 in my head.  Applications and not 
libraries.

So I asked the wrong question anyway.

Thanks for all the pointers!

'apt-cache stats' from the same machine gives:

Total package names: 37481 (750 k)
Total package structures: 37481 (2,099 k)
  Normal packages: 28432
  Pure virtual packages: 390
  Single virtual packages: 3261

  Missing: 5140

Total Provides mappings: 5838 (117 k)
Total globbed strings: 133 (1,465 )
Total dependency version space: 734 k
Total slack space: 49.2 k
Total space accounted for: 10.1 M

Being X-less, there's no Synaptic, however on my sid workstation,
Synaptic reports '39614 packages listed' as being the sum of stats'
'Normal packages' and 'Mixed virtual packages', which would be 28,690
here.

Re: Number of Debian packages available.

2012-10-16 Thread Ralf Mardorf
FWIW tons of packages doesn't mean tons of apps etc., since of the
strange policy to split some packages in an insane way, e.g. the jackd
packages are split really insane. Or does any package depend to libjack
without jackd? And if so, why?

There often is the argument that shared libs will keep a system small,
but bad hard dependencies often enlarge a system. On Arch there e.g. is
a dependency to systemd. I use intitscripts, not systemd, but have got
systemd installed. On Debian for example there's a hard dependency to
pulseaudio for some apps, even if it's completely useless.

And FWIW, meta-packages only summarize some other packages, so the count
of packages gives information about big nothing.

2 Cents,
Ralf

 Because ~s (?section()) doesn't correspond to main/contrib/non-free.

In theory true, but in practice:

$ apt-cache show nvidia-glx | grep ^Section
Section: non-free/x11

This means a search for contrib or non-free with ~s will succeed, but 
not for for main, since packages in main don't advertise the archive 
component in the Section field.

Care to provide some examples? Looking through the reverse dependencies

kde-telepathy-call-ui. If you meant dependency to libpulse, then the

We don't know anything about Lisi's use case, so this is maybe a bit

Jackd could be a suggested dependency, if you don't use jackd, why
should the app link against the lib? The app should link against it, as
soon as you configure the app to use jackd and than you need jackd
completely, not only the lib.

Ok, I only know one GNOME package, but to use GNOME you need this
package.

Yesno. I also like to hear about the count of packages, but this
information is nearly useless.

As far as I know (not my area of expertise, but I have been struggling 
to compile XBMC for my Raspberry Pi recently), such capabilities are 
compile time options.

When you compile an application with output capability to jackd and/or 
pulseaudio the corresponding library becomes a hard dependency (i.e. the 
application may even crash if the library is not installed).

Or would you expect regular users to recompile applications just to 
choose between plain alsa, pulseaudio or jackd output?

Kind regards,
Andrei

No, compiling shouldn't be needed. This is a discussion we very often
had on jack mailing list, when split packages failed.
I don't know why an app should crash, as long as it doesn't try to
access the missing lib. It might crash, I don't know, but it should be
possible to get an app without jackd support and to load jackd support
as a plugin or something like that. There was a mail about Iceweasel and
language support some minutes ago. All language packages get installed
by default, so they could become one package. Ok, it's possible to
remove them manually, after installing, pff, it's also possible to
delete the files manually after installing ;).

Yes, but that depends on how the application is written. Some use 
plugins (vlc), others have compile time options (mplayer, XBMC).
