Module Pretty

Functions for pretty ascii output (colors, etc.)

By default a set of tags are added to stdout and stderr. To activate them call Format.pp_set_tags fmt true. Colors can be added to another formatter with the function add_colors.

Tags must be added to the format string with @{<tag> what you want@}. They can be arbitrarily nested. For instance to print a string in red with part of it bold do

Format.printf "@{<red>I'm red. @{<b> I'm bold red.@}@}"
