Hello ,
I was trying to write a custom function which would run on puppet master
take input a ini file , parse a section of that ini file and assign
its value to a variable .
Something like
$test = iniread('example.ini', 'Program', 'path')
This would assign the value to test variable when the functions runs on the
puppet master.
iniread.rb file looks like
require 'rubygems'
require 'inifile'
module Puppet::Parser::Functions
newfunction(:iniread, :type => :rvalue) do |args|
raise(Puppet::ParseError, 'inifile read(): Wrong number of arguments ' +
"given (#{args.size} for 3)") if args.size != 3
filename = args[0]
section = args[1]
key = args[2]
file = IniFile.load(filename)
data = file[section]
value = data[key]
return value
end
end
It gives an error while running
Error 400 on SERVER: undefined method `[]' for nil:NilClass at
/etc/puppetlabs/puppet/modules/example/manifests/init.pp:45
init.pp has
$test =iniread("example.ini", "Program", "path")
Doing that in ruby works
require 'inifile'
filename = ARGV[0]
section = ARGV[1]
key = ARGV[2]
file = IniFile.load(filename)
data = file[section]
InstPath = data[key]
puts InstPath
Help to this would be really appreciated.
Regards,
Ritesh
