Snakemake 8 compatibility

[tbenavi1]

Hello,

I recently updated my version of Snakemake to version 8, and now Verkko doesn't work. Specifically, I get the following error:

snakemake: error: unrecognized arguments: --reason

According to https://github.com/snakemake/snakemake/blob/main/docs/getting_started/migration.rst, "--reason" is deprecated since it is always true now.

Would it be possible to update Verkko to work with Snakemake 8? Thanks so much.

No plans in the short term (next few months). Snakemake 8 is a major breaking change (like python 3 vs 2) and so, if we support it the users on snakemake 7 would be unable to run verkko. I expect there to still be more users of snakmake 7 than 8 so when we do upgrade I'd hope verkko to detect/use both. For now, I recommend sticking with snakemake 7 and/or using a conda environment to use snakemake 7 for verkko.

When running on python3.12, there are errors w/invalid escape characters and finally an error with the constructed resource strings:

/home/runner/work/verkko/verkko/lib/verkko/Snakefiles/c1-buildStore.sm:55: SyntaxWarning: invalid escape sequence '\`'
  # make sure we weren't given compressed read

Would make sense to address this when we update to Snakemake 8.
