Craig , i looked at that module puppetlabs-inifile, it allows to change
the settings in ini file , i want to read/parse a ini file , assign a
value to a variable.
@henrik you were correct problem was with iniFile.load class . Now the
functions looks like
require_relative 'inifile'
*This allows me to keep inifile.rb file inside the function directory. Is
this correct ?*
Puppet::Parser::Functions.newfunction(
:inireadvalue, :type => :rvalue,
:arity => 3,
:doc => "Reads an .ini file and...") do |args|
filename = args[0]
section = args[1]
key = args[2]
if !File.exist?(filename)
raise(Puppet::ParseError, 'inireadvalue(): Path and file provided does not
exists ' +
'Provide the correct path')
end
fileload = IniFile.load(filename)
data = fileload[section]
value = data[key]
return value
end
Thanks for your help.
Regards,
Ritesh Nanda
