Subject: Fritzing parts are missing
Date: Thu, 10 Nov 2022 02:06:07 +0100

I've come to notice that Fritzing currently does not work in Guix.  The
program starts but greets the user with a bunch of warnings/error
pop-ups.  One being about "142 parts" missing or not being found and
indeed: the parts pane remains empty and Fritzing therefor unusable.

I've come up with the following patch.  It is not optimal (there's still
some warnings and it makes use of an ugly hack to get rid of a certain
"Unable to find parts git repository" message) but with that patch
Fritzing is in a usable state.

It doesn't really matter *what* this returns, right?  At least I 
can't find any observable difference.  And as noted on IRC, this 
‘base32’ format is unique to Guix and Nix.

Could you explain the mechanism behind this, er, mechanism?

Kind regards,

T G-R

Resending this to debbugs since the mail previously was only sent to Tobias


Hi Tobias

Thanks for the review!

The line in question will make all functions return prematurely that are
intended to use libgit2 (that's why the git_libgit2_init is
patched).  Fritzing still reports "Sorry, we have a problem with the
swapping mechanism.
Fritzing still works, but you won't be able to change parts
properties.Error 1", but seems to work fine apart from that.

Since the content of the returned String doesn't seem to matter (as long
as it's not an empty string) I've adjusted it to a less ugly "true".


I'm sorry i don't have the capacity to provide a more satisfying
solution ATM but at least Fritzing is back to a usable state.


Best wishes,
g
