# EasyEnv CLI — 从 catalog.yml 解析模块并 docker compose up/down
# Windows: Git Bash / WSL

ROOT="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
CATALOG="${ROOT}/catalog.yml"

usage() {
  cat <<'EOF'
用法: ./easyenv.sh <list|up|down|path> [module_id]

  list           列出 catalog.yml 中全部模块
  up <id>        在模块目录执行 docker compose up -d
  down <id>      在模块目录执行 docker compose down
  path <id>      打印模块相对路径

示例:
  ./easyenv.sh list
  ./easyenv.sh up mysql
  ./easyenv.sh down redis
