ConfigObj change key=value to key = value which I don't want to

Question

I have conf file with content:

key1=value1
key2=value2
font="\"Font\""

and it's used like values in bash script.

When I change some value with cgi+python3 and ConfigObj 4.7.0:

def set_conf_values(filename, param, value):
    config = ConfigObj(filename)
    config['%s' % param] = value
    config.write()

the conf file is rewriten and the format is new:

key1 = value1
key2 = value2
font = `\"Font\"`

Event for values which is untouched. That's break my Bash script it takes keys as commands...

I hope there is option to avoid that but can't find such thing in docs.

I need \" escape. The problem is that ConfObj add spaces before and after delimiter = — Topper, Jun 17 '19 at 10:20

There does not seem to be any meaningful way to control the output of ConfigObj. ConfigParser, though, has a space_around_delimiters=False keyword argument that you can pass to write.

config.conf:

[section1]
key1=value1
key2=value2
font="\"Font\""

code:

import configparser
from validate import Validator


def set_conf_values(filename, section, param, value):
    config = configparser.ConfigParser()
    config.read(filename)

    print({section: dict(config[section]) for section in config.sections()})
    config[section]['%s' % param] = value
    with open('config2.conf', 'w') as fid:
        config.write(fid, space_around_delimiters=False)

filename = 'config.conf'
set_conf_values(filename, 'section1', 'key2','value2_modified')

config2.conf (output):

[section1]
key1=value1
key2=value2_modified
font="\"Font\""

The dreadful thing about ConfigParser is that it REALLY wants section names. There are elaborate workarounds for this, but this code will get you started.

ConfigObj change key=value to key = value which I don't want to
