# Compass::BrowserSupport

### Constants

ASPECTS
SIMPLE_FUNCTIONS

### Public Instance Methods

add_support(function, *aspects) click to toggle source

Adds support for one or more aspects for the given simple function Example:

    Compass::BrowserSupport.add_support("image", "moz", "webkit")
    # => Adds support for moz and webkit to the image() function.

This function can be called one or more times in a compass configuration file in order to add support for new, simple browser functions without waiting for a new compass release.

    # File lib/compass/browser_support.rb, line 21
    def add_support(function, *aspects)
      aspects.each do |aspect|
        unless ASPECTS.include?(aspect)
          Compass::Util.compass_warn "Unknown support aspect: #{aspect}"
          next
        end
        unless supports?(function, aspect)
          SIMPLE_FUNCTIONS[function.to_s] ||= []
          SIMPLE_FUNCTIONS[function.to_s] << aspect.to_s
        end
      end
    end

has_aspect?(function) click to toggle source

    # File lib/compass/browser_support.rb, line 57
    def has_aspect?(function)
      SIMPLE_FUNCTIONS.has_key?(function.to_s) && SIMPLE_FUNCTIONS[function.to_s].size > 0
    end

remove_support(function, *aspects) click to toggle source

Removes support for one or more aspects for the given simple function Example:

    Compass::BrowserSupport.remove_support("image", "o", "ms")
    # => Adds support for moz and webkit to the image() function.

This function can be called one or more times in a compass configuration file in order to remove support for simple functions that no longer need to a prefix without waiting for a new compass release.

    # File lib/compass/browser_support.rb, line 43
    def remove_support(function, *aspects)
      aspects.each do |aspect|
        unless ASPECTS.include?(aspect)
          Compass::Util.compass_warn "Unknown support aspect: #{aspect}"
          next
        end
        SIMPLE_FUNCTIONS[function.to_s].reject!{|a| a == aspect.to_s}
      end
    end

supports?(function, aspect) click to toggle source

    # File lib/compass/browser_support.rb, line 53
    def supports?(function, aspect)
      SIMPLE_FUNCTIONS.has_key?(function.to_s) && SIMPLE_FUNCTIONS[function.to_s].include?(aspect.to_s)
    end
