dron VS cron

I was annoyed by cron/fcron limitations and figured systemd is the way go because of its flexibility and power, but also was annoyed about manually managing tons of unit files. So I wrote a tool with a config that looks kinda like a crontab, but uses systemd (or launchd on mac) behind the scenes: https://github.com/karlicoss/dron#what-does-it-do

E.g. a simplest job definition looks like this

  job(every(mins=10), 'ping https://beepb00p.xyz', unit_name='ping-beepb00p')

Maybe instead of demons with config files that have more and more bespoke syntax, it's better to go all the way to a library that provides the basic loop functionality? Like https://github.com/c-blake/cron or something similar in C or whatever.

Maybe not, but it's an idea worth considering...

https://github.com/c-blake/cron might interest you. This uses "job" from GP in the sense of "cron jobs", although GP meant something much more broad by "jobs in C". ;-)

The key idea is portable to any prog.lang. you might like, although many will not be as run-time efficient as Nim, C, etc. and many may not be as syntax safe as Nim.
