No, it is as modern package managers work. Also 'port' in MacPorts has 
similar options (they call these packages 'requested'). For example, on 
OSX I have installed only 21 (chosen by me, i.e. *requested*), but the 
total number of package installed (as a result of dependencies) is 254. 
In principle reinstalling the 21 packages should reinstall all the 254 
but sometimes the dependencies change. Having a less package to 
reinstall makes simpler to follow the process of 
installation/re-installation.

I think Cygwin has this (maybe I read this on the list) but I don't 
remember, exactly, the command.. :-(

In any case, Happy New Year.

Ciao,
  Angelo.

Once installed, Cygwin does not distinguish between packages that were 
chosen for installation and those that were installed as dependencies.

This is a shame. As Warren said, this makes it impossible for something like
"apt-get autoremove" to exist on Cygwin. I have request for this already

http://github.com/transcode-open/apt-cyg/issues/26

I am going to implement it, but it will only work for packages installed with
the script, not with setup.exe.

This is the fourth or fifth time you have persisted in this rudeness, even after Yaakov called you down for it the first time and told you it would not be tolerated here.
I’m calling attention to it so he and Corinna will see it for what it is, not just a benign link.

It is not rude. I have made it very clear to Andrey and everyone that his posts
on my threads are not welcome.

If you can find a single time that he has replied contructively to one of my
posts, then perhaps I will reconsider my actions. This includes his reply you
quoted. (hint: it’s not)

And *I* made it clear that you don't get to decide who says what around 
here[1].  You said you were going to abide by this[2], and your further 
participation here is dependent on your doing so.

I wasn't aware that 'apt-cyg' was supported or encouraged on this list 
as a package management tool. If you're looking to add this 
functionality for the benefit of the wider Cygwin community then your 
time would be better spent adding the desired features to 'setup' and 
'cygcheck'.

To that end, Andrey was correct, constructive and concise -

A list of installed packages (no dependencies)

[Angelo Graziosi]

Is there in Cygwin a command to recover a list of installed packages 
chosen by the user without the dependencies?

For example, the archlinux package manager with

pacman -Qqe > pkglist

can save the list of package chosen by the user only and this is useful 
in case one wants/needs to reinstall all the packages.

Happy New year!

Ciao,
  Angelo.

This sounds contradictory to what you're asking above.  If you want to
re-install all the packages, you need the dependencies too to make a
useful (re)install.  To get the list of packages that are currently
installed, use 'cygcheck -cd'.

pacman -e lists only packages explicitly installed, leaving out packages automatically installed to satisfy dependencies.

Basically, it gives you a much shorter list than if you simply list all installed packages, without changing the result if you ask the package manager on a different, freshly-installed box to install “just” those on the shorter list.

DPKG-based OSes must maintain a similar list, because they are able to detect when an automatically-installed package is no longer needed as a result of removing the last explicitly-installed package that depended on it.  (apt-get autoremove).
