What if cron and systemd had a baby?

Project mention: Fcron Is the Best Cron | news.ycombinator.com | 2023-10-14

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')

Thanks!
Multiple targets is definitely the plan, and GLSL is my next priority. Metashade can currently generate HLSL for the DX12 version of https://github.com/ppenenko/glTFSample/tree/metashade_demo, and there's also a Vulkan version of that demo using GLSL. So implementing GLSL generation for that would be a great proof of concept and a test bed: HLSL and GLSL generated from single source and producing identical rendering results.
The diagram on slide 31 of my presentation shows how implementation is currently inherited between the Metashade packages. The future GLSL generators should inherit common functionality from the "rtsl" package, just like the existing HLSL generators. However, I expect heavy refactoring to be necessary because I was initially targeting just one language and so not all code is implemented at the appropriate level.
BTW, here's a poll where you can vote for a target language you'd like to see prioritized: https://github.com/ppenenko/metashade/discussions/17
