Add progress indicator during installation of dependencies

[jan.matousek@…]

During installing dependencies for some port, progress meter would improve the user experience. I see that time progress meter will be impossible (or pretty nontrivial) to add, but simple count of dependencies that will be installed (recursively, see #11892) will greatly improve the knowledge of how much work will be done.

The port output with progress meter can for example look like this:

bash-3.2# port install meld
--->  Installing dependency py-gtk2 (1 / 2)
--->  Fetching py-gtk2
--->  Verifying checksum(s) for py-gtk2
--->  Extracting py-gtk2
--->  Configuring py-gtk2
--->  Building py-gtk2 with target all
--->  Staging py-gtk2 into destroot
--->  Installing py-gtk2 2.12.1_0+darwin_9
--->  Activating py-gtk2 2.12.1_0+darwin_9
--->  Cleaning py-gtk2
--->  Installing dependency py-gnome (2 / 2)
--->  Fetching py-gnome
...

Now the port output look like this:

bash-3.2# port install meld
--->  Fetching py-gtk2
--->  Verifying checksum(s) for py-gtk2
--->  Extracting py-gtk2
--->  Configuring py-gtk2
--->  Building py-gtk2 with target all
--->  Staging py-gtk2 into destroot
--->  Installing py-gtk2 2.12.1_0+darwin_9
--->  Activating py-gtk2 2.12.1_0+darwin_9
--->  Cleaning py-gtk2
--->  Fetching py-gnome
...

With just two dependencies it is no big difference. But when installing whole gnome as dependency, the progress meter becames more helpfull.

Sounds like a good idea. It could become difficult if you specify multiple ports on the command line as we currently don't check how many ports are going to be installed. A change that would also be needed to add a "pretend" option (didn't we already have a ticket for that? Can't find one).

See also #15939.

I've been wanting this :-)

tlmgr has a nice count when you do an update all:

[1/95] linguex...
[2/95] myfont...

etc.

This count of course doesn't delve into dependencies, but even without that it'd a great help to just have some idea.

cc me too. Also it would be good to know if the dependencies include a large build like a different version of gcc.

[ryandesign (Ryan Carsten Schmidt)]

That might be nice, but MacPorts has no information about how "large" a build is.

I think this is similar to #5001
