Rua fails to install split packages where pkgname != pkgbase

[Morganamilo]

For example when installing libc++ rua tries to fetch the libc++abi pkgbuild even though it doesn't exist.

If I try to install libc++abi directly it tries to pull llvm in as a dependency even though it is not a dependency. Hitting M to effectively skip installing it then causes makepkg because of the missing dependency. Even though using makepkg directly works fine.

In order to install libc++abi, the following pacman packages will need to be installed:
  llvm
And the following AUR packages will need to be built and installed:
  libc++abi

Proceed? [O]=ok, Ctrl-C=abort. o

Packages need to be installed:

    pacman -S --asdeps --needed llvm

Enter S to `sudo` install it, or install manually and press M when done. m

And as another example of this there's clion-jre.

[vn971]

Yeah. I know of this problem.. The proper solution is probably to use the AUR web (json) API.

[Morganamilo]

Oh I figured the LLVM dep out now. There used to be an aur package called libc++abi. And because the backing git repo is never removed, rua fetches the very old .SRCINFO file from that.

[vn971]

Oh, I understood it now. We shouldn't git clone when analyzing dependencies then, instead only use it when all dependencies are checked via AUR JSON API, and when user confirms the actions.

It seems sad that we have to rely on AUR JSON API more and more though, to my tastes.
