less_config.rb

##
#
# Awestruct::Extensions:LessConfig is a classic type of awestruct extension.
# If configured in the project pipeline and site.yml it will configure
# the jborg_fonts_path and jborg_images_path Less variables based on site properties.
#
# Configuration:
#
# 1. configure the extension in the project pipeline.rb:
#    - add compass_config dependency:
#
#      require 'less_config'
#
#    - put the extension initialization in the initialization itself:
#
#      extension Awestruct::Extensions::LessConfig.new
#
# 2. This is an example site.yml configuration:
#
#    jborg_fonts_url: https://static.jboss.org/theme/fonts
#    jborg_images_url: https://static.jboss.org/theme/images
#
