IO.ANSI.format
You're seeing just the function
format
, go back to IO.ANSI module for more information.
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 be emitted.
By default checks if ANSI is enabled using the enabled?/0
function.
Examples
iex> IO.ANSI.format(["Hello, ", :red, :bright, "world!"], true)
[[[[[[], "Hello, "] | "\e[31m"] | "\e[1m"], "world!"] | "\e[0m"]
