Got it! I managed to convert my module to Ruby using y2r.

Here’s what I did:

1) install openSUSE 13.1 from scratch (don’t forget to add C/C++ development tools) 2) install all updates and reboot (important! there’s a newer yast2-core in the “oss” repo.) 3) install some needed packages: # zypper in ruby-devel libxml2-devel libxslt-devel unsquashfs

4) extract y2r-master.zip (from https://github/yast/y2r) and run (as root): # gem install y2r

(beware that it needs to download some sources from the internet)

5) extract the base installation media root image: # unsquashfs /boot/x86_64/root

This will create a “squashfs-root” directory. It contains all possible YaST modules that may be referenced in the code.

6) run y2r: # y2r2.0 -M squashfs-root/usr/share/YaST/modules <your YCP module>

And the magic happens.

Now on to debug the Ruby code :)

Great that you succeed, just please do not forget to check if you are affected by well known bugs in y2r - https://github.com/yast/y2r/blob/master/KNOWN_BUGS.md especially escaped characters can do some mess. Usually easiest way to check it is grep ycp source for escaped characters and manually fix ruby sources. If you need any help with debugging ruby source, don't hesitate to ask here or on our IRC freenode#yast Josef

Hello all,

I finally had time to try converting my YCP module again. As mentioned earlier, I had to upgrade my yast2-core to something after 2.24.x. I tried upgrading just this package on openSUSE 12.3 (using the package from 13.1), but apparently it___d break a LOT of stuff.

I decided to try upgrading the whole system to 13.1, recompiled y2r___ and now it fails further while trying to load LibStorage.so. I tried feeding it the LibStorage.so from the installation image via LD_PRELOAD, but got an ___undefined symbol: PL_thr_key___ error. Since the installation image used Perl 5.16.2 and I am now on Perl 5.18, I downgraded Perl to 5.16 with the same results.

I saw in another forum that this missing symbol indicates that this .so module was compiled in a pthread-enabled Perl interpreter, and the one supplied with the system is not, which I find odd. Where can I find the source to LibStorage.so so I can recompile it, or is there a way to skip loading it in y2r?

No, there is no way to skip it, but it looks like strange upgrade way, as in 13.1 we do not get such bug report.
