For values that depend on runtime state (e.g., available environments, project names):
# In bash completion, call the CLI with --json for machine-readable output
local items=$(mycli list --json 2>/dev/null | jq -r '.[]' 2>/dev/null)
COMPREPLY=( $(compgen -W "${items}" -- "${cur}") )
Print setup instructions when running mycli completion:
# Bash: Add to ~/.bashrc
eval "$(mycli completion bash)"
# Zsh: Add to ~/.zshrc
eval "$(mycli completion zsh)"
# Fish: Run once
mycli completion fish > ~/.config/fish/completions/mycli.fish
mycli completion bash | bash # Should not error
mycli completion zsh # Should output valid zsh script
mycli completion fish # Should output valid fish script
