Here's a modified version that supports sections:

data = File.read("filename.ini")

ini_hash = {}
ini_hash[""] = section_hash = {}   # default unnamed section

data.each do |line|
   if /^\[.+\]$/ =~ line    # section headers are surrounded by brackets
     ini_hash[line.chomp.gsub(/[\[\]]/, '')] = section_hash = {}
   else
     key,value = line.chomp.split("=")
     section_hash[key] = value
   end
end

# example of walking through the whole thing
ini_hash.each do |k, v|
   puts "-#{k}-"
   v.each {|sk, sv| puts "  #{sk}=#{sv}"}
end

# example of accessing a value by section and key
v = ini_hash['section']['key']
