Quite often colors are used not to format all of the text in color, but to highlight certain parts of it. The function ansicolor.highlight_string takes this a bit further by allowing you to pass in a list of pairs that represent the start and end offsets in the string that you want highlighted.
../snippets/using_highlights_1.py
Every list of pairs that is passed in is considered a highlighting layer and gets a new color. Where layers overlap this is indicated by applying:
- bold (two layers overlap),
- reverse (three layers overlap),
- bold and reverse (four layers overlap).
Four layers is the maximum, because after that there is no further distinction possible. See ansicolor.demos.demo_highlight for an exhaustive example.
