are there are any snippets of joker code online or larger projects written in joker? I tested some small scripts
Joker is not really intended for "large" projects, whatever "large" means. I think its sweet spot is scripts / automation. We use it for some infrastructure automation / glue, and our largest script is ~ 1.3K of LOC, not counting @hlship’s multi library (https://github.com/hlship/multi). That said, if anyone uses Joker for something more sophisticated it'd be very interesting to hear about it.
Joker v0.15.4
is released https://github.com/candid82/joker/releases/tag/v0.15.4
