parse_icons_from_icomoon.rb

# Usage:
# run the file with the dev.svg from icomoon (not the plain svg)
# ruby parse_icons_from_icomoon.rb /path/to/iconfont.dev.svg

require 'nokogiri'

file = ARGV[0]

svg = File.open(file)
document = Nokogiri::XML(svg)
glyphs = document.css('glyph')

name_and_chars = glyphs.map do |glyph|
  name = glyph['data-tags'].to_s.downcase.gsub(/[- \_]/, '_').gsub(/[^a-z0-9\_]/, '')
  char = glyph['unicode'].to_s
  [name, char]
end

name_and_chars = name_and_chars.reject {|name, char| name == '' || char == ''}
name_and_chars = name_and_chars.sort

string = name_and_chars.map{|name, char|
  "  #{name}: '#{char}'"
}.join(",\n")

puts "{\n#{string}\n}"
