Owner

Feature

Provide shell completion for gpg-publish that covers:

Flags: --check, --verbose, --nsupdate, --ttl, --domain, --label-only, --version
Target argument: Complete email addresses from the private GPG keyring (gpg --list-keys --with-colons to extract UIDs), file paths, and the literal - for stdin.

Approach options

Built-in completion output — Add a --completion bash|zsh|fish flag that emits the shell-specific completion script (like kubectl completion bash).
External completion scripts — Ship static completion files in a completions/ directory.

Option 1 is more maintainable since the completion stays in sync with the actual flags.

Key completion

For the target argument, offer completions from:

gpg --list-keys --with-colons 2>/dev/null | awk -F: '/^uid:/ {print $10}' | grep -oP '<\K[^>]+'

This lists all email addresses in the user's public keyring.

Shells to support

bash (most common on Linux servers)
zsh (default on macOS)
fish (nice to have)
