Homebrew packages aren't correctly counted on M1 macs

[jasonappah]

Hi there! I've been using macchina in my terminal setup for a while and it's been awesome! I noticed that macchina reports the wrong number of installed brew packages on Apple Silicon Macs. macchina displays 0, and I confirmed with brew list that I've got a lot more than that :)

It looks like libmacchina is trying to manually count installed packages in /usr/local/Cellar and /usr/local/Caskroom, but when being run with Apple Silicon CPUs, brew installs ARM packages by default to /opt/homebrew/Caskroom and /opt/homebrew/Cellar, which I'm assuming is to avoid conflicts with any potential x86 packages installed for use under Rosetta.

I think the solution to this should just be to switch the root path based on the current system architecture, but perhaps it'd be better to count packages installed for all architectures and not just the one currently being used? I'm not a huge Rust person but I'd love to help out where I can!

Output of `brew list -1 -l` (I'm just noticing the zero count here too 🤔 )

Hi!

If I understand correctly, you'd like to see libmacchina count the packages in:

• /opt/homebrew/Caskroom
• /opt/homebrew/Cellar
• /usr/local/Caskroom
• /usr/local/Cellar

If on Apple Silicon the last two directories don't exist, then their count will be "0", and it'll just return the count of the first two.

EDIT: We count things in-house, so don't worry about that "0" count there. EDIT 2: Should be fixed with https://github.com/Macchina-CLI/libmacchina/commit/4067dc4d474426889eadd2a6989ca8d876df0c4f EDIT 3: See https://github.com/Macchina-CLI/libmacchina/commit/168daf164a1d472f260ea720e039b57e853a6fd3 as the previously mentioned commit was failing because of some variable naming issues.

It shouldn't take long for a new release to come out that features this new change, so I guess I'll close this for now.

EDIT: v1.1.7 is out but give it some time for the homebrew team to update it in their repos :)

[jasonappah]

Awesome - thanks for pushing a fix so quickly!

[grtcdr]

Of course :)

And thank you for taking the time to write us a detailed report.
