argcomplete does not work with aws-vault

I’ve got custom Python script and added argcomplete to it using instructions from https://kislyuk.github.io/argcomplete/. One note - I need to call it using aws-vault cause my script works with Amazon and I need credentials setup before script logic work.

If I call my lptl.py directly autocomplete works:

$ python3 lptl.py --
--ansible-repo-path    --help                 --skip-app-start       --test-slaves-count
--app-version          --servers-list         --test-environment     --test-slaves-ips
--config               --show-test-plan-only  --test-scenario-name   
--debug                --skip-app-deploy      --test-scenario-path

But when I call it with wrapper, it is not, pressing TAB after following command line results to nothing:

$ aws-vault exec shared-test-full -- python3 lptl.py --

Could anybody help solving this issue?

BTW, I use macOS.

P.S.: Also I’ve got virtualenv, don’t know if it affects, but I installed argcomplete both to local and global environments.

Solved by incapsulating aws-vault call into Python script and passing environment from it to internal aws subprocess calls. Now autocompletion works fine.

argcomplete does not generally work with arbitrary command line wrappers. To understand why, check the section of the documentation describing the protocol (https://kislyuk.github.io/argcomplete/#argcomplete-autocomplete-parser). When you run your command through a wrapper, the wrapper must be aware of the argcomplete protocol (in particular, it must forward fd 8 to the wrapped subprocess). I don’t think it’s possible to make argcomplete work with this utility.
