Re: Bug#246305: zsh: completion for sudo doesn't add commands under root's path

[Clint Adams <clint@zsh.org>]

This is how to achieve the equivalent effects with the patch at the
bottom, which could probably use some deuglification/optimization.
Should I commit?

> zstyle ':completion:*:sudo:*' command-path delete . .. '../*'

zstyle -e ':completion:*:sudo:*' command-path 'reply=(${path:#(.|..|../*})'

> zstyle ':completion:*:sudo:*' command-path append /usr/local/bin /opt/bin

zstyle -e ':completion:*:sudo:*' command-path 'reply=($path /usr/local/bin /opt/bin)'

> zstyle ':completion:*:sudo:*' command-path prepend ~/bin /usr/local/bin

zstyle -e ':completion:*:sudo:*' command-path 'reply=(~/bin /usr/local/bin $path)'

> zstyle ':completion:*:sudo:*' command-path assign /bin /usr/bin /usr/sbin

zstyle ':completion:*:sudo:*' command-path /bin /usr/bin /usr/sbin

zstyle -e ':completion:*:sudo:*' command-path 'reply=(~/bin $path /usr/local/bin /opt/bin)'
Though I don't see the significance of path order.
