Sets primary (default) font
Elixir v1.2.6 IO.ANSI
Functionality to render ANSI escape sequences.
ANSI escape sequences are characters embedded in text used to control formatting, color, and other output options on video text terminals.

Types
Functions
Sets foreground color
Sets the foreground color from individual RGB values.
Valid values for each color are in the range 0 to 5.
Sets background color
Sets the background color from individual RGB values.
Valid values for each color are in the range 0 to 5.
Checks if ANSI coloring is supported and enabled on this machine.
This function simply reads the configuration value for
:ansi_enabled in the :elixir application. The value is by
default false unless Elixir can detect during startup that
both stdout and stderr are terminals.
Formats a chardata-like argument by converting named ANSI sequences into actual ANSI codes.
The named sequences are represented by atoms.
It will also append an IO.ANSI.reset/0 to the chardata when a conversion is
performed. If you don’t want this behaviour, use format_fragment/2.
An optional boolean parameter can be passed to enable or disable
emitting actual ANSI codes. When false, no ANSI codes will emitted.
By default checks if ANSI is enabled using the enabled?/0 function.
Examples
iex> IO.ANSI.format(["Hello, ", :red, :bright, "world!"], true)
