# span-codeman.sh — open a Codeman window stretched across ALL displays, so that
|
|
# in-page floating session panels can be dragged from one physical monitor to
|
|
# the other. Spawned by the header "multi-monitor" button (POST
|
|
# /api/system/span-displays), or run by hand at the desk.
|
|
#
|
|
# ── PREREQUISITE (one-time, manual) ──────────────────────────────────────────
|
|
# System Settings → Desktop & Dock → turn OFF "Displays have separate Spaces",
|
|
# then LOG OUT and back in. Until you do, macOS keeps every window on a single
|
|
# display and this script's window will clamp to one monitor instead of spanning.
|
|
# (Equivalent CLI: `defaults write com.apple.spaces spans-displays -bool true`,
|
|
# still needs a re-login. Revert with `-bool false`.)
|
|
#
|
|
# Why a maximized --app window and not fullscreen: browser fullscreen is
|
|
# per-display and will NOT span. We size a windowed app to the union of all
|
|
# displays instead. macOS only.
|
|
#
|
|
# ── REMOTE CLIENT (Codeman server on another machine) ────────────────────────
|
|
# The header "multi-monitor" button spawns this script SERVER-SIDE, so it opens
|
|
# the window on the SERVER's displays and is gated to a macOS server. If your
|
|
# Codeman runs elsewhere (e.g. a headless Linux box reached over Tailscale) and
|
|
# YOUR monitors are on a Mac, the button can't help — the server can't open a
|
|
# window on your machine. Instead, run this script LOCALLY on the Mac and pass
|
|
# the remote URL as the argument:
|
|
# ./span-codeman.sh "https://your-codeman.example.ts.net"
|
|
# The osascript/browser launch all happen on the Mac; only the page is served
|
|
# remotely, so the spanning window lands on your monitors. The "separate Spaces"
|
|
# prerequisite above still applies on the Mac.
