# Extended Formatter that supports ANSI colors.
#
# The basic mapping of ANSI colors is as follows:
#
# | reset | bold | dark | underline | blink | negative
# MOD | 0 | 1 | 2 | 4 | 5 | 7
#
# | black | red | green | yellow | blue | magenta | cyan | white
# FG | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37
# BG | 40 | 41 | 42 | 43 | 44 | 45 | 46 | 47
#
# The output is done by: "\e[#{mod};#{fg};#{bg}m#{string}\e[0m"
# The suffix is to reset the terminal to the original state again.
