That output makes sense! Your simple PKGBUILD doesn't contain the source variable, which I'd say is required, even if empty (edit: no, source mustn't be empty!)

After adding a source line source=('test'), the output is fine, only complaining about missing checksums, Maintainer tag, description in PKGBUILD, url and license.

It is a valid PKGBUILD. It should not error with a lack of source array. Note that the Arch Linux "base" package has no source array.

sekret, I don't know what would give you the idea that the source array is required. See metapackages, for example.

Sorry, my comment was bullshit! Please ignore :-( It's clearly a bug!

Reassigning to the actual namcap maintainer...

This appears to be a regression from  FS#23258 .
Furthermore this issue also occurs on PKGBUILDs with architecture-specific sources, like anydesk-bin from the AUR:

I stumbled about this bug while trying to run namcap on base ("asp checkout base && cd base/trunk && namcap PKGBUILD" leads to exception "KeyError: 'source'"). What is preventing it from being fixed?

It is fixed in namcap-git, currently we're just waiting for a release is all.

What's the expected time before a new namcap is being released? This bugs me each time, namcap is being re-packaged (and thus, my manual patch is being overwritten by pacman again).

Also wondering - it's either not fixed or the same bug has regressed again
