But, if you wish to... (:

./run-with-env.sh /path/to/ida -A /path/to/idb.i64

• Buy IDA Pro (very important)
• Install IDA Pro (also very important)
• ln -s $PWD $HOME/.idapro/plugins/idagui
• Make sure IDA is using the same python 3.12 as uv is using
  • This step might be unnecessary for 9.2, I've heard
• uv sync
• See the above Usage section

uv sync --all-groups && code .

Why not?
