I went hunting today, for a package that I had used to colorize text. There are tons of those out there of course. But - what if you want to filter the text and colorize based on a set of rules?
There's probably a lot of stuff out there for that, too. Colord for example, runs as a daemon in Linux.
Another package, is grc, found at this GitHub site: https://github.com/garabik/grc
Use Case:
I had a log that was printing information related to exchanges with different servers. I decided to color these so that messages from Server A were green, Server B were blue, etc. In this way, I could do really cool things like suppress messages from Server B (no colorization). Or, I could take Control Plane messages from, say, Server C, and highlight those Yellow.
This came in very handy during a Demo, where people were watching the messages display in rapid succession on a large screen.
