I'm afraid I'm going to have to orphan this package as the upstream maintainer has made katrain exceedingly difficult to package in a way that aligns with AUR best practices (at least, it's beyond my skill/ability to do so). Using pip to install packages within a pkgbuild is not the "proper" way to do it, but the setuptools workflow has been removed making pip the only method of installation AFAICT.

For now it looks like installing directly from upstream using pip and/or poetry is probably the best way to go until someone with more knowledge of how to package build systems like this is able to take over.

Just an update on kivymd, it looks like the katrain maintainer started work on bumping the kivymd version to 1.x but the branch has been idle since September. It would be a big help to the project to contribute if anyone has the skills or interest!

For now, the workaround unfortunately is to manually downgrade to python-kivymd 0.104.2/0.104.1.

Sorry for the delay on updating--it looks like v1.15 changed the build/install system quite a bit and I need to iron out those issues.

As an alternative way of installing and running Katrain, this might work:

pacman -S python-pipx
pipx install katrain
~/.local/bin/katrain

About the issue I reported earlier: I installed katrain using pipx install katrain, and now it works. Not sure what the difference is between the pip version and the aur version.

After a recent update of my system (manjaro), Katrain freezes right after I try to place a stone on the board. Tried reinstalling, then deleting the .katrain folder, as well as downgrading the only dependency that was upgraded in the last update (python-certifi), but nothing seems to work. Any help would be appreciated. Thank you!

I tried to pin the depends version of python-kivymd to 0.104.1 as mentioned but I got an error stating python-kivymd=0.104.1 as a missing dependency.

I assume I've just done something stupid, but can anyone show the relevant section of the PKGBUILD file for reference?

[...]you can modify the PKGBUILD to build 0.104.2 instead

Note that only 0.104.1 works.

With 0.104.2, you get the following MRO errors:

What version of python-kivymd do you have installed? The current version in the arch repos (1.x) is incompatible with katrain unfortunately--you can modify the PKGBUILD to build 0.104.2 instead

Seems that I spoke far too soon. I tried running Katrain and it simply will not load. I ran it with the debug option enabled and this was the output:

@bradwood & @alegebro, yes it builds just fine now and thank you for your work. I'm sure many of us appreciate it. :) I know I certainly do (despite not being able to beat Katrain even on a 9x9 as yet)!
