# List, monitor status, and jump across opencode popup sessions from a single
# picker — plus persistent per-agent indicators in every tmux status line.
# Source this file from your tmux config:

#   run-shell ~/.config/tmux/plugins/tmux-opencode-session-manager/opencode_session_manager.tmux

# It reads user options (with sensible defaults) and installs the key bindings.
#
# Floating vertical indicator stacks are impractical in tmux: the only overlay
# primitives are popups and menus, which cover terminal content and vanish on
# dismissal. The persistent per-agent indicators therefore live as a compact
# right-aligned group in status-right (bottom-right, just left of the
# hostname) — the only native always-visible UI. One indicator per tracked
# agent: a state glyph plus a short directory label.

# --- Persistent status-line indicators ---------------------------------------
# Prepend the statusline segment to status-right, preserving the user's
# existing content and styling. The segment hides itself while the picker
# popup is open (picker.sh sets @opencode_picker_open for exactly that
# span): the picker already shows every agent's state, so the indicators
# would only duplicate it. Idempotent and self-healing across reloads: the
# previously installed segment (remembered verbatim, so glob metacharacters
# in styles can't misfire) is stripped by length before the current one is
# prepended, so re-sourcing never duplicates and upgrades apply.
