Testing wanted: Bash completions overhaul

[DannyBen]

Hey all,

I have updated how Bashly generates Bash completions, through Completely.
This is a substantial overhaul, but it is intended to be backwards compatible.

If your Bashly project uses Bash completions, I would love your help testing the new implementation and reporting anything that looks wrong.

You can install the Bashly prerelease with:

gem install bashly --pre

This prerelease depends on a prerelease of Completely, so the matching completion generator should be installed automatically.

What changed

• Generated completion scripts are now position-sensitive instead of simple list-based completions.

• Generated completions no longer re-offer flags that were already provided.

• Positional args can now be completed according to their position.

• Positional args with allowed will include those values in the generated completions.

• Args now support their own completions list:

  args:
  - name: path
    help: File or directory to process
    completions:
    - <file>
    - <directory>

• Command-level completions is still supported for backwards compatibility, but is no longer the recommended way to define positional-arg completions:

  commands:
  - name: view
    help: View a directory, system user, or git branch
    completions:
    - <directory>
    - <user>
    - $(git branch 2> /dev/null)

What needs real world testing

• Completion generation on existing Bashly projects should produce useful, functional Bash completions.
• Args and flags with allowed or completions should suggest those values in the right place.
• Existing command-level completions should still work for positional args that do not define their own allowed or completions.

If you test this, please comment with your Bashly version, shell/Bash version, and a small config snippet or reproduction if something does not behave as expected.
