Yes, the grep script parses the JSON for compatible gnome-shell verions numbers to set up the depends array correctly. Surprisingly, also traditional tools like grep are regularly updated still today, find exactly the weird unintended behaviour I rely upon to do so and forbid it. The issue affected all my gnome-shell-extension-* packages and is fixed now. More details can be found in the respective commit to the package collection <https://github.com/dffischer/gnome-shell-extensions/commit/785f0a35c7760de237ddfe2e53c959132be200d1>.

Thanks for pointing out the change in metadata.json. It is indeed most probably the culprit. I will fix this in the next few days.

Hi, There is a bug in the PKGBUILD: gnome-shell-extension-maximus-two-git/PKGBUILD: line 52: compatibles: bad array subscript It is probably because the metadata.json is written differently. In the last Github master version: "shell-version": [ "3.16", "3.18" ], The bug is caused by this: local compatibles=($(\ find -path ./pkg -type d -prune -o \ -name metadata.json -exec grep -Pzo '(?s)(?<="shell-version": \[)[^\[\]]*(?=\])' '{}' \; | \ tr '\n," ' '\n' | sed 's/3\.//g;/^$/d' | sort -n -t. -k 1,1)) cat metadata.json depends+=("gnome-shell>=3.${compatibles[0]}") local max="${compatibles[-1]}" # <---- It stops here with the error below

When trying to install, I get the following error: grep: unescaped ^ or $ not supported with -Pz /tmp/pacaurtmp-user/gnome-shell-extension-maximus-two-git/PKGBUILD: line 51: compatibles: bad array subscript

I get the following error, if I try to install the extension: Error: Schema org.gnome.shell.extensions.maximus could not be found for extension maximus@luis.pabon.auronconsulting.co.uk.

You should add 'wmctrl' as a dependency. Without it, the extension will generate a long list of error notifications that read "Execution of 'wmctrl' failed: Command not found" (as well as, obviously, not working).

This extension is not developed any further long since and does not work with Gnome Shell 3.16 and up. Users are advised to switch to gnome-shell-extension-maximus-two-git.

Added xorg-xprop as a dependency, fixed url.

Please add xorg-xprop as dependency. Fails without it.
