How to extract from rpm

[kpcyrd]

Hello! :)

I found this parsing library and I already figured out how to use rpm::Package::parse and get_file_entries(), but I couldn't figure out how to read a file from the archive. It seems rpm::FileEntry does not have any way to be read.

Do you have any pointers?

Thanks!

There isn't an API for that yet unfortunately. We absolutely need one though. Maybe I can find some time for that this week.

This for the quick reply, is there a way I could work around this in the meantime? :)

The payload is (99.999% of the time) just a standard SVR4 CPIO archive. You can process it with a CPIO library of choice.

I see, I assume it's available in this field (which makes sense):

In the meantime I wrote a somewhat chaotic solution based on /usr/bin/bsdtar:
