Question

Given the following format (.properties or .ini):

propertyName1=propertyValue1
propertyName2=propertyValue2
...
propertyNam         


        

Answer 1

This is what i had written to parse file and set it as env variables which skips comments and non key value lines added switches to specify hg:d

• -h or --help print usage summary
• -c Specify char that identifies comment
• -s Separator between key and value in prop file

• and specify properties file that needs to be parsed eg : python EnvParamSet.py -c # -s = env.properties

  import pipes
  import sys , getopt
  import os.path
  
  class Parsing :
  
          def __init__(self , seprator , commentChar , propFile):
          self.seprator = seprator
          self.commentChar = commentChar
          self.propFile  = propFile
  
      def  parseProp(self):
          prop = open(self.propFile,'rU')
          for line in prop :
              if line.startswith(self.commentChar)==False and  line.find(self.seprator) != -1  :
                  keyValue = line.split(self.seprator)
                  key =  keyValue[0].strip() 
                  value = keyValue[1].strip() 
                          print("export  %s=%s" % (str (key),pipes.quote(str(value))))
  
  
  
  
  class EnvParamSet:
  
      def main (argv):
  
          seprator = '='
          comment =  '#'
  
          if len(argv)  is 0:
              print "Please Specify properties file to be parsed "
              sys.exit()
          propFile=argv[-1] 
  
  
          try :
              opts, args = getopt.getopt(argv, "hs:c:f:", ["help", "seprator=","comment=", "file="])
          except getopt.GetoptError,e:
              print str(e)
              print " possible  arguments  -s  -c < comment char >     \n  Try -h or --help "
              sys.exit(2)
  
  
          if os.path.isfile(args[0])==False:
              print "File doesnt exist "
              sys.exit()
  
  
          for opt , arg  in opts :
              if opt in ("-h" , "--help"):
                  print " hg:d  \n -h or --help print usage summary \n -c Specify char that idetifes comment  \n -s Sperator between key and value in prop file \n  specify file  "
                  sys.exit()
              elif opt in ("-s" , "--seprator"):
                  seprator = arg 
              elif opt in ("-c"  , "--comment"):
                  comment  = arg
  
          p = Parsing( seprator, comment , propFile)
          p.parseProp()
  
      if __name__ == "__main__":
              main(sys.argv[1:])
