How to set environment variables in vscode for debugging?

Question

I have a fairly large python/c++ program that runs as follow:

. set_env.sh -option A -option B
python run.py

The set_env.sh script modifies the PYTHONPATH and does all sort of export in order to point to the right c++ program. When running these two commands in the terminal, that works just well, however, using the debugger breaks it all.

I try running ". set_env.sh -option A -option B" in preLaunchTask but it seems the debugger can't see the new PYTHONPATH.

How can I make the debugger run the the set_env and consider the new PYTHONPATH ?

I had a similar problem and could solve it by setting environment variables in the "env" field of the launch.JSON file. This shoudl be stored in a .vscode folder in your project root, here is the docs: https://code.visualstudio.com/docs/python/debugging

I discovered the "env" field in this snippet here: https://gist.github.com/slaveofcode/b4c18efc99c16029913cde3fd2dba3ce

Not sure how to configure this dynamically with the -option A -option B however. Hope this helps :)
