# example-usage.sh — Example showing how to use the tailscale-gitea module
# Issue: timmy-home#385 — Standardized Tailscale IP detection module

set -euo pipefail

# --- Basic Usage ---
# Source the module to automatically set GITEA_BASE_URL
SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
source "${SCRIPT_DIR}/tailscale-gitea.sh"

# Now use GITEA_BASE_URL in your API calls
echo "Using Gitea at: $GITEA_BASE_URL"
echo "Tailscale active: $GITEA_USING_TAILSCALE"

# --- Example API Call ---
# curl -sf -H "Authorization: token $TOKEN" \
#   "$GITEA_BASE_URL/repos/myuser/myrepo/issues"

# --- Custom Configuration (Optional) ---
# You can customize behavior by setting variables BEFORE sourcing:
#
#   TAILSCALE_TIMEOUT=5    # Wait 5 seconds instead of 2
#   TAILSCALE_DEBUG=1      # Print which endpoint was selected
#   source "${SCRIPT_DIR}/tailscale-gitea.sh"

# --- Advanced: Checking Network Mode ---
if [[ "$GITEA_USING_TAILSCALE" == "true" ]]; then
  echo "✓ Connected via private Tailscale network"
else
  echo "⚠ Using public internet fallback (Tailscale unavailable)"
fi

# --- Example: Polling with Retry Logic ---
poll_gitea() {
  local endpoint="${1:-$GITEA_BASE_URL}"
  local max_retries="${2:-3}"
  local retry=0

  while [[ $retry -lt $max_retries ]]; do
    if curl -sf --connect-timeout 2 "${endpoint}/version" > /dev/null 2>&1; then
      echo "Gitea is reachable"
      return 0
    fi
    retry=$((retry + 1))
    echo "Retry $retry/$max_retries..."
    sleep 1
  done

  echo "Gitea unreachable after $max_retries attempts"
  return 1
}

# Uncomment to test connectivity:
# poll_gitea "$GITEA_BASE_URL"
