Python: how to handle imports #1535

Open maximiliankaul opened 1 month ago

maximiliankaul commented 1 month ago

How should we handle imports in Python? The current approach (VariableDeclaration without fqn) is not satisfactory and should be improved. What is the correct way to model this in the CPG?

Import Alias
FQN
Multiple imports in one import_stmt
Type: class? variable? ...?
relative module paths
import *

@KuechA re-started this discussion.

Probably similar as I do it in Go, but the whole system probably needs to be overhauled. Also slightly related to #1533

import * from X is basically the same as using namespace X in C++ import aliases also handled in Go with the aliases property in the scope manager, but this is a rather ugly hack

We can start working on this, once #1536 is merged.
