aws_completer does nothing: is it Arch or AWS?

0BADC0DE · 2026-03-12 16:58:30

The aws_completer tool thayt comes with extra/aws-cli-v2 (mine is v2.33.22-1) does nothing.
It's supposed to output something to implement shell auto-completion.
It outputs nothing, thus the question so I can file a bug.

TIA

import os

if os.environ.get('LC_CTYPE', '') == 'UTF-8':
    os.environ['LC_CTYPE'] = 'en_US.UTF-8'
from awscli.autocomplete.main import autocomplete


def main():
    # bash exports COMP_LINE and COMP_POINT, tcsh COMMAND_LINE only
    command_line = (
        os.environ.get('COMP_LINE') or os.environ.get('COMMAND_LINE') or ''
    )
    command_index = int(os.environ.get('COMP_POINT') or len(command_line))

    try:
        autocomplete(command_line, command_index)
    except KeyboardInterrupt:
        # If the user hits Ctrl+C, we don't want to print
        # a traceback to the user.
        pass


if __name__ == '__main__':
    main()

Adding a couple of print command like these:

    print(command_line)
    print(command_index)

reveals that the command_line string is empty ('') while command_index is 0.
My question still stands.

I don't know this.

Do the docs help?

That tool is/was supposed to generate bash autocompletion stuff.

You have to perform some steps to make it work.

for bash it would be this command :

$ complete -C '/usr/bin/aws_completer' aws

(taken from https://docs.aws.amazon.com/cli/latest/ … etion.html )
