[python] Properties file in python (similar to Java Properties)

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))))
