highlighting for sudo commands

[oschmid]

zsh can complete commands that are on root's path but not on user's path by adding the following to .zshrc

zstyle ':completion:*:sudo::' environ PATH="/sbin:/usr/sbin:$PATH" HOME="/root"

But these commands aren't being properly highlighted by zsh-syntax-highlighting. Instead of green (valid command) they are appearing red (invalid command). Is there a setting similar to environ to change this?

I just checked this bug. It seems to have been fixed since it was reported.

So let us close it.

Can you describe the working setup? I can still reproduce it on debian with zsh-5.1 under zsh -f, even if I set both the environ and command-path styles. It only works for me if I add /sbin to my $PATH.

(Reopening until we figure this out.)

[guidovansteen]

Sorry for the noise. /sbin was added my $path when I tried this earlier today. Thanks for reopening!

In 0.4.1 commands from root's path are highlighted in red. During 0.5.0 development they were shown in default (like any not-otherwise-special word), but 757d047 (in 0.5.0-to-be) restores the behaviour of 0.4.1.

Various ideas:

• Can we obtain the secure_path option from sudoers(5)?
• We could inspect the environ PATH or command-path completion style in the :completion:…:sudo context. (Why that context? Because that's the context the style definition's context patterns would match. Yes, this is somewhat hacky.)
• We could take a wild guess with ${path//\/bin/\/sbin}.

Or we could do something else entirely:

• Never highlight the foo in sudo foo as an unknown command.
