### Attributes

options[RW]

### Public Class Methods

new(options = {}) click to toggle source

Create a new instance, valid options are in DEFAULT. In the background a new thread will be running that checks the QUEUE and processes all messages that are being sent to it. This is done to make output nicer and readable.

    # File lib/ramaze/log/xosd.rb, line 53
    def initialize(options = {})
      @options = DEFAULT.merge(options)

      super(@options[:lines])

      @options.each do |key, value|
        next if IGNORE.include?(key)
        value = @options[:font_size] if key == :font
        send("#{key}=", value)
      end

      Thread.new(self) do |xosd|
        loop do
          items = []
          lines = xosd.options[:lines]
          items << QUEUE.shift until QUEUE.empty? or items.size >= lines

          unless items.empty?
            # pad up with empty lines to avoid dragging around old messages.
            items << [:info, ' '] until items.size >= lines

            items.each_with_index do |(tag, message), i|
            xosd.color = xosd.options[:colors][tag.to_sym]
            xosd.display(message, i)
            end
          end
          sleep xosd.options[:timeout]
        end
      end
    end

### Public Instance Methods

log(tag, *messages) click to toggle source

Pushes all messages it gets on the QUEUE for further processing.

    # File lib/ramaze/log/xosd.rb, line 87
    def log(tag, *messages)
      messages.each do |message|
        QUEUE << [tag, message]
      end
    end
