--init show zsh: parse error near `>&'

[alps2006]

A strange problem on z.lua --init

z.lua$ eval "$(lua z.lua --init)" 
# output error
zsh: parse error near `>&'

I found the error location at -h|--help) local arg_mode="-h" ;;, and i resolved by escaping --help , but why only --help?

which version of zsh are you using? I haven't encountered this before in zsh.

Thanks for your reply, the detail is below.

I am not sure if there is some side effect (mostly in other shells) when changing -- to \--. so I made another revise, please try out the latest version:

I have found the reason why i cannot use --help only, because there is a global alias that overrides --help entirely.

# bat to render --help
alias -g -- --help='--help 2>&1 | bat --language=help --style=plain'

thank you very much, i close it.
