Arch Linux User Repository

prepare() is eyebrow-raising. Firstly, VCS packages usually package a "nightly" release -- I would expect this package to be tracking master, not the latest release. Further, instead of doing the checkout manually, you could instead append #tag=$_latest_release (with _latest_release computed as currently) to the source URL to have makepkg do the checkout for you (I don't recommend it, but it's better than the status quo).

Next, pkgver() can be dramatically simplified, given upstream tags their releases properly -- it suffices to use

git describe --tags --long | sed  's/^[^0-9]*//;s/\([^-]*-g\)/r\1/;s/-/./g'

Also, please use PEP517 builds, as explained in wiki.

Finally, and most significantly, you're missing a bunch of the dependencies -- see setup.py for details. (I'll skip adding the tests, given this is already getting long)

The below fixes these (and also adds =$pkgver to provides as explained in https://gitlab.archlinux.org/pacman/namcap/-/issues/96)
