Configuration settings library

[misterlisty]

Is there a library or method to store settings(preferably in json) that survives reboots.

[misterlisty]

Haven't tried yet, but assume the file has to have an initial json string first?

@misterlisty I'm not sure what you want me to say, other than the fact that you probably have a syntax error in your JSON file

i get an error... syntax error in JSON

@misterlisty You need to make an object instead of using it like a method, and not use keyed params. Example:

from config import Config
c = Config()
c.get("existing_key")
c.set("existing_key","whatever_value")
c.save()

[misterlisty]

from config import Config

try:
Config.set(key="here",value="there") #failes with function missing required positional argument #0
Config.save()
devname = Config.get("here")
print("devname",devname)
except Exception as e:
print("config testfailed",e)

Just use the json lib and open/write it manually. Something like this

import json

class Config:

    def __init__(self,filename="config.json"):
        self.filename = filename
        self.data = self.__read_file()

    def __read_file(self):
        with open(self.filename) as data:
            return json.load(data)

    def set(self,key,value):
        self.data[key] = value

    def get(self,key):
        return self.data[key]
    
    def save(self):
        with open(self.filename,'w') as f:
            f.write(json.dumps(self.data))
