Use ANSI escape codes https://en.wikipedia.org/wiki/ANSI_escape_code to put some colors on the terminal.
This uses tags in format strings to specify the style. Current styles are the following:
Example:
set_color_default true;;
Format.printf
"what is your @{<White>favorite color@}? @{<blue>blue@}! No, @{<red>red@}! Ahhhhhhh@.";;status: experimental
val set_color_tag_handling : t -> unitadds functions to support color tags to the given formatter.
set_color_default b enables color handling on the standard formatters (stdout, stderr) if b = true as well as on sprintf formatters; it disables the color handling if b = false.
with_color "Blue" pp behaves like the printer pp, but with the given style. status: experimental
with_colorf "Blue" out "%s %d" "yolo" 42 will behave like Format.fprintf, but wrapping the content with the given style status: experimental
val to_string : 'a printer -> 'a -> stringval stdout : tval stderr : tPrint into a string any format string that would usually be compatible with fprintf. Similar to Format.asprintf.
Similar to sprintf but never prints colors
Alias to Format.fprintf
val ksprintf :
f:(string -> 'b) ->
('a, Format.formatter, unit, 'b) format4 ->
'aksprintf fmt ~f formats using fmt, in a way similar to sprintf, and then calls f on the resulting string.
