sourcing a python config file?

I wrote simple python program that rips, encodes, and gets song data from the cddb. I would like to give the user the option of customizing it to there taste. So I want to make a config file that I can store in /etc/pythonriprc or in ~/.pythonriprc. for example it would look like this

config file

Code:

# if you would like to specify the location of you music directory uncomment the following

#music_dir = '/home/shane/location/of/directory'

# if you would like to permantey set the bitrate used please unmcooment the following

#bit_rate = 192

is their a way to direct my script to use the variables set is this file?

You could use something like this section of the python tutorial. (As a shortcut, look into execfile()).

Something like this would work:

Code:

import re



pattern = "\'(.*?)\'"



file = open('/path/to/config.conf', 'r')

for line in file.readlines():

    if line.startswith('music_dir'):

        music_dir = re.findall(pattern, line)[0]

        print music_dir

    elif line.startswith('bit_rate'):

        bit_rate = re.findall(pattern, line)[0]

        print bit_rate

        

file.close()

Basically all this does is check each line to see if it starts with either 'music_dir' or 'bit_rate'. If it does then it extracts the string that is between the single quotes and sets that to the variable. So everything would have to be inside single quotes. The config would look like this:

Code:

# if you would like to specify the location of you music directory uncomment the following

music_dir = '/home/shane/location/of/directory'

# if you would like to permantey set the bitrate used please unmcooment the following

bit_rate = '19'

This is pretty limited but it does the trick.

@Crashed_Again

that would work :-) No need to reinvent the wheel, which I do all to often. I usually spend half a day working on an algorythm, then find out later there was aready a module made for the task.

thanks Matir for the link, it seems something as simple as

Code:

execfile('/etc/pythonrip.rc')

would work.

No problem. You might want to check if the file exists first, just to be clean about it. :)

I will do something like this

Code:

import os

if os.path.isfile('/etc/pythonriprc.py'):

    execfile('/etc/pythonriprc.py')

Yep, that makes sense. Might want to spit an error/warning if it doesn't exist, depending on how badly you want them to have such a config file :)

Ideally I wnat to use Distutils to install my modules, main script and config file. I looked at the docs, it semed a little involved , but not to hard.
