From 6b3ab420ad6e4ffbd12ae8f6c0b4d95488d941c9 Mon Sep 17 00:00:00 2001 From: Jonny Barnes Date: Sun, 9 Aug 2026 12:38:16 +0100 Subject: [PATCH] Follow light/dark appearance in the tmux status bar MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The status bar was five hardcoded tangere-dark colours, so in light mode the pale #fdfdd9 text landed on a white background and became unreadable. That was the real reason Auto appearance "never worked with the terminal setup" — ghostty was switching correctly all along. Split the colours into tmux-light.conf and tmux-dark.conf. The dark file is extracted byte-exact from the previous config; the light file is the same layout with each colour swapped for the tangere-light palette entry at the same index, so roles are preserved (text on an accent uses the theme background, which inverts from #1a2938 to #fdfdfa). tmux 3.6+ learns the terminal's theme over OSC 2031, so this keys off the appearance change itself rather than a schedule, and behaves identically whether that came from Auto at sunrise/sunset or a manual toggle. Three hooks: the two theme hooks react to a change, and client-attached covers a client attaching mid-way, since those two only fire on a change. Sourcing is idempotent so the overlap is harmless. This replaces the dark-mode-notify launchd agent removed in 59d5622, which could not have worked: it re-sourced .zshrc inside each shell, but the status bar belongs to the tmux server. Verified by round trip: flipping to Light switched #{client_theme} and applied the light palette, and returning to Dark restored it. A running nvim does not follow a live change (docs: the TUI sets 'background' on startup); noted in the README.
