On Void, `helm-system-packages` asks about missing apt dependencies

[emacsomancer]

When I run helm-system-packages in Emacs on my Void machine, I get the message:

Dependencies are missing (apt-get, apt-cache, apt-mark), please install them

I don't see anything in the instructions about specially configuring the system to know that it's Void.

I also tried (require helm-system-packages-xbps) but that only give me one additional command helm-system-packages-xbps-refresh, which seems to work, but does not give me an interface to system packages.

Thanks for the report.

The xbps package is clearly outdated, but the setup should not be. Look at https://github.com/emacs-helm/helm-system-packages/blob/master/helm-system-packages.el#L637, you'll see it should try to detect XBPS based on the existence of the xbps-query command.

Now it's weird that it matches dpkg for you. Do you have a dpkg command on your system? What does which dpkg return in a shell?

[emacsomancer]

Yes, I did have the (in the Void repos) dpkg package installed (I don't recall what for); removing it resolved the issue (is there a way to manually/forcefully choose which package manager to have helm-system-packages attach to? rather than letting it automatically do so? In the case I need the dpkg package installed, for instance?)

[Ambrevar]

Sadly no. But there is an easy fix: extract the package manager list from the `helm-system-packages' function into a variable. The user could then customize the variable to choose what is looked up.

I can't fix this right now. Would you be able to send a patch? I'd happily merge it then :)

[emacsomancer]

Yes, I can work on a patch, though it might take me a little bit to get round to this.
