Parsing Puppet YAML log in Python

[Sharuzzaman Ahmat Raslan]

Hi all,

Yesterday I emailed Kirill Simonov, the creator of PyYAML, to get help to parse Puppet YAML file.

He gladly helped with the following code. This code is for parsing Puppet log, but I'm sure you can modify it to parse other Puppet YAML file.

The idea is to create the correct loader for the Ruby object, then PyYAML can read the data after that.

Here goes the code:

#!/usr/bin/env python

import yaml

def construct_ruby_object(loader, suffix, node):


    return loader.construct_yaml_map(node)



def construct_ruby_sym(loader, node):


    return loader.construct_yaml_str(node)



yaml.add_multi_constructor(u"!ruby/object:", construct_ruby_object)


yaml.add_constructor(u"!ruby/sym", construct_ruby_sym)




stream = file('201203130939.yaml','r')


mydata = yaml.load(stream)


print mydata

Thanks!  I had just figured this out myself about a week ago :)  I didn't think to post to the group.
