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.@}@}"

The font tags available are:

n : normal
b : bold
/b : cancel bold
dim : dimmer color
u : underline
/u : cancel underline
i : italicize
/i : cancel italicize
/bl : cancel blinking

The color (foreground) tags are:

black
red
green
yellow
blue
magenta
cyan
gray
default
c:0-255 give directly the color number on 256 colors terminals

And their bright version

black_b
red_b
green_b
yellow_b
blue_b
magenta_b
cyan_b
gray_b
default_b

The background color tags are:

bg_black
bg_red
bg_green
bg_yellow
bg_blue
bg_magenta
bg_cyan
bg_gray
bg_default

And their bright version

bg_black_b
bg_red_b
bg_green_b
bg_yellow_b
bg_blue_b
bg_magenta_b
bg_cyan_b
bg_gray_b
bg_default_b
