[Solved] How to retrieve just pkgver from an installed package

Package A is installed

Package B depends on A and needs to be set to the same version package A has.

pacman -Q somename | sed 's/somename //'

Does remove the name but leaves the pkgrel value .
It's also not suitable to put directly in a string .

How to use the version of A in the pkgver() function of B ?

This sounds like a bad idea from the start. Why would the pgkver of B depend on A? It's then *not* the pkgver of B but something else entirely. A package's pkgver depends on it's own source. You can have versioned dependencies if you need the same versions installed, but having B misrepresent what version it is would not support this goal at all.

But if you really just want a sed command to extract the version number:

... | sed 's/[^ ]* \([^-]*\)-.*/\1/'

The AUR llvm-minimal-git package has been getting more complex and an increased number of splits for various reasons .

I am considering to switch it to separate packages (similar to llvm/clang in repos ) that will build from a specific snapshot of the sourcecode .

Puttting the snapshot in its own package seems like a simple way to ensure all use that exact version .
I could have all of them run the same pkgver() used in the snapshot package, but copying the value from the snapshot pacakge feels cleaner .

Your sed command does deliver the value.

Edit : getting the command output into a var was easy using a bashism.
