I have a very tricky situation (for my standards) in hand. I have a script that needs to read a script variable name from ConfigParser. For example, I need to read
self.post.id
from a .cfg file and use it as a variable in the script. How do I achieve this?
I suppose I was unclear in my query. The .cfg file looks something like:
[head]
test: me
some variable : self.post.id
This self.post.id is to be replaced at the run time, taking values from the script.
test.ini:
[head]
var: self.post.id
python:
import ConfigParser
class Test:
def __init__(self):
self.post = TestPost(5)
def getPost(self):
config = ConfigParser.ConfigParser()
config.read('/path/to/test.ini')
newvar = config.get('head', 'var')
print eval(newvar)
class TestPost:
def __init__(self, id):
self.id = id
test = Test()
test.getPost() # prints 5
This is a bit silly.
You have a dynamic language, distributed in source form.
You're trying to make what amounts to a change to the source. Which is easy-to-read, plain text Python.
Why not just change the Python source and stop messing about with a configuration file?
It's a lot easier to have a block of code like this
# Change this for some reason or another
x = self.post.id # Standard Configuration
# x = self.post.somethingElse # Another Configuration
# x = self.post.yetAnotherCase # A third configuration
it's just as complex to change this as it is to change a configuration file. And your Python program is simpler and more clear.
