From 9ee64797011b541b38e68610a746eb6f303ab63d Mon Sep 17 00:00:00 2001 From: Anton Hvornum Date: Sun, 21 Mar 2021 15:04:23 +0100 Subject: Enabling load_instructions() to set a temporary namespace, and then reverting it after the instructions are loaded. This is to temporarly override the namespace during import - enabling avoidance of triggering __name__ checks, and at the same time reverting back the namespace automatically to enable .execute() on the script (reusability of classes) --- archinstall/lib/profiles.py | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) (limited to 'archinstall') diff --git a/archinstall/lib/profiles.py b/archinstall/lib/profiles.py index 5d425a22..ef7bba00 100644 --- a/archinstall/lib/profiles.py +++ b/archinstall/lib/profiles.py @@ -125,7 +125,9 @@ class Script(): else: raise ProfileNotFound(f"Cannot handle scheme {parsed_url.scheme}") - def load_instructions(self, namespace=None): + def load_instructions(self, namespace=None, reset_namespace=False): + original_namespace = self.namespace + if namespace: self.namespace = namespace @@ -135,6 +137,9 @@ class Script(): print(f"Imported {self} into sys.modules with namespace {self.namespace}.") + if reset_namespace: + self.namespace = original_namespace + return self def execute(self): @@ -173,7 +178,7 @@ class Profile(Script): # if __name__ == 'moduleName' if '__name__' in source_data and '_prep_function' in source_data: print(f"Checking if {self} has _prep_function by importing with namespace {self.namespace}.py") - with self.load_instructions(namespace=f"{self.namespace}.py") as imported: + with self.load_instructions(namespace=f"{self.namespace}.py", reset_namespace=True) as imported: if hasattr(imported, '_prep_function'): return True return False -- cgit v1.2.3-54-g00ecf
