zmodule add homebrew completion with if condition

[cattyhouse]

According to homebrew
they have completion files in $(brew --prefix)/share/zsh/site-functions
and the dir has something like this on my system : _bat _brew _fd _mpv _rg _yt-dlp

so adding in .zimrc

...
zmodule /opt/homebrew/share/zsh --fpath site-functions
zmodule completion
...

works like a charm.

But NOT this:

zmodule $(brew --prefix)/share/zsh --fpath site-functions
# zimfw says : no matches found: $(brew --prefix)/share/zsh

And NOT even this with a if condition:

if type brew &>/dev/null && [[ $(uname) == Darwin ]] ; then zmodule /opt/homebrew/share/zsh --fpath site-functions ; fi
# not working

any suggestions? thanks

EDIT: i wanted to add a if condition because my .zimrc is shared with a bunch of linux machines.

You need to set Homebrew's environment variables before trying what you shared above:

eval "$(/opt/homebrew/bin/brew shellenv)"

I personally have this in my .zprofile to ensure it's evaluated before my .zshrc (and therefore before Zim).

(source: Homebrew installation script, which explicitly prompts the user to add this line to .zprofile)

@antoineco thanks, that will export HOMEBREW_PREFIX, so i can use it within .zimrc, that's wonderful. what about the if condition.

[antoineco]

It will also update your PATH so type brew will also work.

[cattyhouse]

oh right, i forgot the $path issue. thanks again!

finally i come up with a clean and arbitrary if condition without adding the eval to .zprofile:

# in ~/.zimrc
if [[ -d /opt/homebrew/share/zsh ]] && [[ $(uname) == Darwin ]] ; then
    zmodule /opt/homebrew/share/zsh --fpath site-functions
fi
# but before
zmodule completion

• Warp : does not add the completion provided by brew.
• Terminal & iTerm2 : everything works here. 🎉

For Intel

# in ~/.zimrc
if [[ -d /usr/local/share/zsh/site-functions ]] && [[ $(uname) == Darwin ]] ; then
    zmodule /usr/local/share/zsh/site-functions --fpath .
fi
# but before
zmodule completion

For ARM | M1 ..

# in ~/.zimrc
if [[ -d /opt/homebrew/share/zsh ]] && [[ $(uname) == Darwin ]] ; then
    zmodule /opt/homebrew/share/site-functions --fpath .
fi
# but before
zmodule completion

thanks, we can also test [[ $(uname -m) == arm64 ]] , true if it's Apple Silicon, false if it's Intel.
