# launch-tui.sh — build and launch the TUI against a remote anchor.
# Starts a local daemon then opens the Bubble Tea terminal UI.
#
# SETUP: copy this file to launch-tui.sh (gitignored) and set ANCHOR below.
#
# Usage:
#   ./launch-tui.sh
#   ALIAS=alice NETWORK=friends ./launch-tui.sh
#
# Optional env vars (all have defaults):
#   ANCHOR      anchor WebSocket URL          (required — edit below)
#   NETWORK     network name to join          (default: "friends")
#   ALIAS       display name                  (default: $USER)
#   DATA_DIR    identity + message store dir  (default: ~/.waste-$ALIAS)
#   IPC_PORT    local daemon IPC port         (default: 17337)
#   SHARE_DIR   directory to share with peers (optional)
