The Extension Loader

The loader is a simple script that loads extensions one by one from the ext_dir as specified in the config.toml file.

The code looks like this

def load_extension(path, name):
    sys.path.append(path)
    try:
        return importlib.import_module(name, package=path)
    except ImportError:
        return None

Hence, any extension that has the same name as other extensions the user already has installed or is part of the standard library, can cause conflicts. It is recommended not to name them so.

Every extension must have a pre_fetcht and post_fetch functions. pre_fetch is called before a repository is fetched and post_fetch after as shown below. Both the functions should take in a url as a parameter.

def pre_fetch(url):
    # do something

def post_fetch(url):
    # do something
