IO ANSI Plus

Build Status

Functionality to render ANSI escape sequences. Clone of module IO.ANSI but supporting named Xterm colors.

Installation

Add io_ansi_plus to your list of dependencies in mix.exs:

def deps do
  [
    {:io_ansi_plus, "~> 0.1"}
  ]
end

Notes

In addition to the 16 standard ANSI colors<sup>1</sup> and their background counterparts, this package also supports the 256 Xterm colors (foreground and background).

Most of these 256 colors were given names like:

For the full list of color names, see the Color Samples section below.

You can use color number atoms for the few colors that are unnamed:

alias IO.ANSI.Plus, as: ANSI
["Hello, ", :color163, "world!"] |> ANSI.format(true) |> IO.puts()
["Hello, ", :color163_background, "world!"] |> ANSI.format(true) |> IO.puts()

Any color can have multiple names, for example, :moccasin and :navajo_white for color code 223.

For details, see file config/persist_colors.exs.

Shortcuts

The package also provides shortcuts to drop the format calls in the following expressions:

alias IO.ANSI.Plus, as: ANSI
["Hello, ", :brown, "world!"] |> ANSI.format(true) |> IO.puts()
["Hello, ", :purple, "world!"] |> ANSI.format(true) |> IO.write()
[:aqua, "Garry, your move:", :reset, " "] |> ANSI.format(true) |> IO.gets()

The above expressions can be respectively shortened to:

alias IO.ANSI.Plus, as: ANSI
["Hello, ", :brown, "world!"] |> ANSI.puts(true)
["Hello, ", :purple, "world!"] |> ANSI.write(true)
[:aqua, "Garry, your move:", :reset, " "] |> ANSI.gets(true)
