@pier4r I run it through bolt for convenience but language is the same so this can also run with puppet:

romain@zappy ~/Projects/aoc % bolt apply day2.pp -t localhost
Starting: install puppet and gather facts on localhost
Finished: install puppet and gather facts with 0 failures in 2.8 sec
Starting: apply catalog on localhost
localhost: Scope(Class[main]): 13809
localhost: Scope(Class[main]): 12316
Started on localhost...
Finished on localhost:
  changed: 0, failed: 0, unchanged: 0 skipped: 0, noop: 0
Finished: apply catalog with 0 failures in 4.44 sec
Successful on 1 target: localhost
Ran on 1 target in 7.29 sec
romain@zappy ~/Projects/aoc % puppet apply day2.pp --modulepath $PWD/..
Warning: Scope(Class[main]): 13809
Warning: Scope(Class[main]): 12316
Notice: Compiled catalog for zappy.blogreen.org in environment production in 0.81 seconds
Notice: Applied catalog in 0.01 seconds

The ideal would in fact be a plan, so that we do not need to pass an unneeded target 😄 :

romain@zappy ~/Projects/aoc % mkdir plans
romain@zappy ~/Projects/aoc % echo 'plan aoc::day2 {' > plans/day2.pp
romain@zappy ~/Projects/aoc % cat day2.pp >> plans/day2.pp
romain@zappy ~/Projects/aoc % echo '}' >> plans/day2.pp
romain@zappy ~/Projects/aoc % bolt plan run aoc::day2
Starting: plan aoc::day2
13809
12316
Finished: plan aoc::day2 in 0.8 sec
Plan completed successfully with no result

I really have to use bolt, I thought it was a tad different but it seems like scriptable puppet. I am losing opportunities there.
