My application was 100% developed in pure Python. I found very useful and easy to create a config file with
.py extension and than simply load it in every code. Something like this:
ENV = 'Dev' def get_settings(): return eval(ENV) class Dev(): ''' Development Settings ''' # AWS settings aws_key = 'xxxxxxxxxxxxx' aws_secret = 'xxxxxxxxxxxxxxxxx' # S3 settings s3_bucket = 'xxxxxxxxxx' ... ...
And than in my code I just import this file and use settings, this way I have one file that easy to manage and that contains all aprameters I need.
Howewer recently I had to move part of my code to Java. And now I’m struggling with configurations.
What are the “standard” way to create a config that would be easily accessible from both languages? (My Java skills are very limited, if you can five me a brief example in Java it would be great)
Have a look at ConfigParser in Python
The syntax on this file looks like this:
[Section] my_option = 12.2 my_option2 = other_value [Section2] my_voption = my_value
You read it this way:
import ConfigParser config = ConfigParser.ConfigParser() config.read('example.cfg') config.getfloat('Section', 'my_option') # returns 12.2
It works for a couple of types and if you can’t find a type, you can use the
eval function in Python. Finding an equivalent to Java shouldn’t be too hard. Or even parsing this file using Java shouldn’t be too hard.
