Developpers

If your favorite DNS provider is missing from the list, please consider contributing. Your class just needs to inherit from Updater and possess the following methods to work in dynDNS_updater

class YourProviderUpdater(Updater):
    def initialize(self):
        your_logic = "please write unit tests along the way"

    def check_and_update(self):
        your_logic = "please write unit tests along the way"

Onboarding

• poetry: dependency manager
• black: code formater

git clone https://github.com/zar3bski/dynDNS_updater.git
cd dynDNS_updater
poetry install 

This will create a virtual env with all dev dependencies
