ansicolors.lua

ansicolors is a simple Lua function for printing to the console in color.

Installation

Put the file ansicolors.lua somewhere where your Lua interpreter will be able to find it. Then:

  local ansicolors = require 'ansicolors'

Usage

  local colors = require 'ansicolors'
  print(colors('%{red}hello'))
  print(colors('%{redbg}hello{%reset}'))
  print(colors('%{bright red underlined}hello'))

Testing

This application uses telescope in order to perform the tests. Install telescope, and then execute

  tsc specs/ansicolors_spec.lua

Notice that the tests will only work on an ANSI-compatible machine (windows isn’t ANSI-compatible)

Windows

Windows console, by default, isn’t capable of handling ANSI color codes correctly. This library tries to detect whether it is on a windows machine (by looking at package.path) and in that case it suppresses all ANSI control characters (the text appears devoid of color, but legible).
