This is my code for the Advent of Code 2019 puzzles, done in the muon programming language. This is a very new, incomplete and in-development programming language that I just started using for fun, so the solutions might be less elegant than they could/should be!
To build, install muon and run:
# $MUON_LIB should point to the muon/lib directory from the muon repo
$ mu ${MUON_LIB}/*.mu --args main.args
