#!/bin/sh
# Waybar custom/pacdiff: shows count of unresolved .pacnew/.pacsave files.
# Source of truth is `pacdiff -o` (output mode — lists differing files,
# does nothing). Hidden when zero. Mako fires once when the count goes
# from "no problems" to "non-zero" (i.e. on the post-`pacman -Syu`
# settle), so you're nudged exactly once per upgrade wave.
#
# Click handler runs `DIFFPROG='nvim -d' sudo pacdiff` in a floating
# ghostty. DIFFPROG is propagated through sudo-rs by the env_keep policy
# in etc/sudoers-rs (no -E needed — env_keep is unconditional pass-through).
