Small helper utility to make your CLI program output 🌈 coloured by means of configurable markup styles. Think of it as your CLI-mate :)

1. Add the dependency to your shard.yml:

   dependencies:
     climate:
       github: Sija/climate.cr

2. Run shards install

require "climate"

message = "Usage: {#{PROGRAM_NAME}} <required-arg> [optional-arg]"

# you can call `Climate.parse` method directly
puts Climate.parse(message)

# or use a `String#climatize` extension
puts message.climatize

Default styles are:

• <> colored in green (keeping delimiters)
• [] colored in yellow (keeping delimiters)
• {} colored in blue (hiding delimiters)
• !¡ colored in red (hiding delimiters)

You can change the global settings with a #configure block:

Climate.configure do |settings|
  # use defaults
  settings.use_defaults!

  # and/or configure your own styles
  settings.styles << Climate::Style.new(
    delimiters: {'?', '¿'},
    keep_delimiters: false,
    colors: {
      fore: :magenta,
      back: :default,
    },
    decoration: :bold
  )
end

For the colors and decoration reference values see documentation for the Colorize module (which Climate uses under the hood).
