Package escapes has a handful of useful functions for when you're wanting to send formatting escape sequences to the terminal while tracking the width of your output for alignment purposes. The escape sequences always restore things back to 'normal' when done, which could be considered suboptimal when adding styles but keeps things sane. This does not use terminfo, and just relies on ECMA-48 and related ANSI standards; see https://en.wikipedia.org/wiki/ANSI_escape_code for too much and yet too little detail.
