Terminal Command to generate list of numbers from human readable representation - Atreyagaurav/numrng

This feels like it should already be a feature in a terminal. But I didn't find anything that let me do this efficiently.

I had a rust library for converting list like 1-4,8-10 into vectors, but thought I'd expand it into a command line command as well, as it is really useful when I want to run batch commands in parallel using templates.

I wanted to share it since it might be a useful simple command for many people.

Bash can do discontinuous ranges
undefined

$ echo {{1..3},{7..8}} 1 2 3 7 8
- Thank you. I did think there might be a way.
  My program is basically doing printf "%d\n" {{1..3},{7..8}} in that case. Can bash do step? like 1:2:10 would be 1,3,5,7,9
  
  Yes, just give the step as the third number: {1..10..2}
  
  {1..10..2}
  Wow, that's nice to know. I guess my program will at least make it easier since you can type it in a more humane way, but not essential.
  
  There's also seq:
  undefined
  
  $ seq 1 2 10
  This will print the numbers starting from 1, incrementing by 2 until you get to 10.
  
  Seq will only print one sequence, though. The program's focus is discontinuous range. Something like: 1:2:10,20:2:30
