Linux: OpenSUSE package count about pfetch-rs HOT 5 CLOSED

What distro did you base your bedrock installation on and what package manager are you using?

from pfetch-rs.

openSUSE Tumbleweed and original pfetch used Bedrock's package manager(pmm) to check how many packages are installed

from pfetch-rs.

Thank you for reporting this. I couldn't find the usage of either pmm or zypper in the original pfetch source code (these are all package managers checked) so it is strange that it counted them for you there. The solution seems to be to implement a zypper package count (ideally in libmacchina).

from pfetch-rs.

I just looked more into this and this issue lead me down a rabbit hole.

libmacchina already supports RPM package count, which is the backend used by zypper by interacting with its sqlite database directly. However, it turns out that RPM also supports different database formats (bdb and ndb), where ndb is used by OpenSUSE. It will probably be really hard to create an implementation that directly accesses this ndb file, as this is a RPM native database implementation with no libraries I could find supporting it (for more detail see Macchina-CLI/libmacchina#154).

So to get a package count on OpenSUSE, the options are to either change the RPM backend from ndb to sqlite (has to be done by the user), work on an implementation that gets the info from the bdb file directly (really hard) or just invoke an rpm process like the original pfetch did it (really slow).

I will probably implement the last one for now to have a package count on OpenSUSE (although being really slow) that can be disabled with the PF_FAST_PKG_COUNT option similar to nix.

With version 2.6.1, openSUSE package count has gotten significantly faster, as long as the rpm-devel package is installed.
