I'm interested in the rainbow library (which does reference figlet https://github.com/arsham/rainbow/blob/master/README.md#see-...), but only to see if it's any faster than the painfully slow Ruby implementation of lolcat.
There are a couple of benchmarks and you can run them with: $ go test -bench=.
It's funny that despite the fact that GUIs with mice, menus and things have been around for a bloody long time: you can't beat a terminal prompt for many tasks. Mind you my terminals these days looks rather better than the twinax connected beasts of yesteryear that I looked after. I don't remember transparency options on those.
Have a look at https://github.com/nojhan/liquidprompt for more eye-candy for your prompt - it does look rather good and I've been using it on one machine for at least a year with no snags. However that project may be needing an active developer judging by the last commit and Issues.
This does not reduce the enormous efforts of the author to include all the different ecosystems, thought.
