Shell completion (Bash)

[yermulnik]

I'm looking into adding Bash completion locally. Per the https://github.com/benkehoe/aws-sso-util#quickstart the "main" command to produce shell completion code is _AWS_SSO_UTIL_COMPLETE=source_bash aws-sso-util, which I don't know why produces empty output for me — is this expected/known or did I manage to tangle my local setup somehow?

aws-sso-util is installed via Homebrew and OS is Ubuntu Jammy if it might be important:

> brew info aws-sso-util

Appreciate any help.

I'm afraid I can't be of much help directly; shell completion is a feature of click, the CLI library. The docs for completion are here: https://click.palletsprojects.com/en/8.1.x/shell-completion/ let me know if you do or don't make progress!

@benkehoe Does this mean that _AWS_SSO_UTIL_COMPLETE=source_bash aws-sso-util does produce non-empty output to you?

[benkehoe]

Aha: I missed updating the documentation. In click 8 (which aws-sso-util requires as of v4.31), the value changed from source_bash to bash_source (and similar for other shells) (no idea why). It was working for me using the click 8 docs, but the links in the README here and the example were using the click 7 version.

@benkehoe Worked like a charm! Thanks a lot for looking into this!
