Hi, I'd like to propose a feature to pacman/makepkg, allow users to create new meta-packages quickly.
Just let them define name,[description],and dependencies.

I imagine something like:
$pacman --meta myNvidia --desc "local NV install with openCL" --depends nvidia, opencl, someother<=1.3.37

which would create a PKGBUILD with appropriate (name,desc,depends, provides,conflicts) fields, download deps, call makepkg, pacman -U the meta-package.


#1 no more forgotten opt-depends

disadvantage of today's optdepends is they are installed as explicit, so when i go through my list of packages to removed unused ones, I usually wonder what that lib/pkg is good for there. Meta pkg would handle this gratefully.

#2 work projects

I tend to work on several projects, where each requires specific apps for work, so I install them, when the project is over, I would like to wipe them off, but usually forget which were those.

$pacman --meta midi --desc "computer generated music" --depends abcmidi,mp32midi,dino

I think I could implement this in shell, but dont have enough pacman knowledge to do it in pacman itself.

What do you think about the idea and design?
I believe the implementation part shouldnt be too complex, as all tools are already in place, just to hook them up appropriately.

Cheers, Mark

This task depends upon

I really don't think this functionality belongs in pacman or makepkg. This is far more appropriate as a standalone tool. I don't know if it's still around, but I think Xyne once provided a tool that did what you want:


and there's still his somewhat related tool makedep that you may want to look at:

Ok, thanks for the links. I believe it could be a nice feature for pacman/makepkg (as for example, support for installing from cvs repos and colors is comming to makepkg)
Anyways, I mentioned Xyne here: https://bugs.archlinux.org/task/11337 (btw, nice bug# :), and asking for metapax sources + his opinion).
Mentioned to "yaourt people" here: https://aur.archlinux.org/packages/yaourt/ ,because I didnt find other place to reach upstream.

Metapax's main function was simply to convert a file containing a name, description and a list of packages to a PKGBUILD and build it. It would be easier to write a script from scratch than sift through the Metapax functions to see how it works.

After I wrote the above, I took a look at the old code and started to rewrite a simplified version, but I quickly realized that the easiest way would be to simply create the .PKGMETA file manually and add it to an empty tar.xz archive.

Fwiw, I agree that this functionality is better left to a separate utility.

Xyne, thanks for looking at the sources. What do you mean by a .PKGMETA file?

If you dont think pacman is a good place, I'll either make a separate script, or try to add it to yaourt/packer.

Should the bug be closed?

Sorry, I meant .AURINFO files. Read the release announcement for AUR 2.1.0: https://mailman.archlinux.org/pipermail/aur-dev/2013-March/002428.html

I think you should make a separate script. It is a package creator and should not be shoehorned into a package manager.

You can probably request closure of this thread as I doubt it will ever be implemented in Pacman.

Yes, Andrew! Wow. That's exactly what I've been wanting! :)
Would you like to make an AUR package? Or should I.

Many thanks, this is perfect.

Feel free to make an AUR package, I don't have any plans to.

One more, big KUDOS Andrew! :)
The pkg is in AUR, everyone enjoy.

I think we can close .. me going consolidate all the packages accumulated throught time.
