Most of these utilities appear to rely upon embedding commands into the
OS SHELL prompt. You could embed pretty much anything to be run as part of
the prompt display. https://github.com/dvorka/hstr/blob/master/CONFIGURATION.md#bash-history-settings
Since source for HSTR is available, nothing prevents you from recoding
everything in Python -- though I'm fairly certain Python may be a bit
slower unless you can take advantage of compiled C libraries (regex,
perhaps). Based upon the animated GIF, you'll have to master the curses
library from Python.
