An escape sequence starts with an <ESC> +## character (commonly \e[), followed by one or more formatting codes +## (its possible) to apply more that one color/effect at a time), +## and finished by a lower case m. For example, the formatting code 1 +## tells the terminal to print the text bold face. This is acchieved as: +## \e[1m Hello World! +## +## But if nothing else is specified, then eveything that may be printed +## after 'Hello world!' will be bold face as well. The code 0 is thus +## meant to remove all formating from the text and return to normal: +## \e[1m Hello World! \e[0m +## +## It's also possible to paint the text in color (codes 30 to 37 and +## codes 90 to 97), or its background (codes 40 to 47 and 100 to 107). +## Red has code 31: +## \e[31m Hello World! \e[0m +## +## More than one code can be applied at a time. Codes are separated by +## semicolons. For example, code 31 paints the text in red. Thus, +## the following would print in red bold face: +## \e[1;31m Hello World! \e[0m +## +## Some formatting sequences are, in fact, comprised of two codes +## that must go together. For example, the code 38;5; tells the terminal +## that the next code (after the semicolon) should be interpreted as +## a 256 bit formatting color. So, for example, the code 82 is a light +## green. We can paint the text using this code as follows, plus bold +## face as follows - but notice that not all terminal support 256 colors:## +## \e[1;38;5;82m Hello World! \e[0m +## +## For a detailed list of all codes, this site has an excellent guide: +## https://misc.flogisoft.com/bash/tip_colors_and_formatting +## +## +## +## +## +## TODO: When requesting an 8 bit colorcode, detect if terminal supports +## 256 bits, and return appropriate code instead +## +## TODO: Improve this description/manual text +## +## TODO: Currently, if only one parameter is passed, its treated as a +## color.
