Moreutils's ts C implementation
I searched for ts written in C for better performance and less memory consumption, and I found nothing. So I decided to write m own ts in C.
PROS & CONS: Moreutils ts: pros:
- available in repositories
- configurable with patterns cons:
- slow on big files
- big memory footprint (relatively)
Moreutils ts C: pros:
- fast
- small memory footprint
- suitable for embedded cons:
- not in distro repos
- don't have pattenrs (WIP)
