dot_xen

=======

A gem that provides reading and writing of xen files

Usage

=====

mpro% irb            

>> require 'lib/dot_xen'

=> true

>> puts XenConfigFile::Parser.new.simple_parse(File.read("spec/fixtures/ey00-s00348.xen")).to_s

#  -*- mode: python; -*-

kernel = "/boot/vmlinuz-2.6.18-xenU"

memory = 712

maxmem = 4096

name = "ey00-s00348"

vif = [ "bridge=xenbr0" ]

root = "/dev/sda1 ro"

vcpus = 1

cpu_cap = 100

disk = [ 

         "phy:/dev/ey00-data4/root-s00348,sda1,w",

         "phy:/dev/ey00-data4/swap-s00348,sda2,w",

         "phy:/dev/ey00-data4/gfs-00218,sdb1,w!",

         ]

=> nil

There's two parts to this

The .simple_parse traverses the tree and builds the representation using the models in lib/xen/ast.rb.  It'll return nil if the document is invalid.
