# --- 日志配置 ---

# 1. 确保日志目录存在
LOG_DIR = "logs"
if not os.path.exists(LOG_DIR):
    os.makedirs(LOG_DIR)

LOG_FILE = os.path.join(LOG_DIR, "vs_app.log")

# 2. 定义日志格式 (包含时间)
# 格式示例: [2023-10-27 10:30:01] [INFO] [MainThread] [TAG] Message...
LOG_FORMAT = '[%(asctime)s] [%(levelname)s] [%(threadName)s] %(message)s'
DATE_FORMAT = '%Y-%m-%d %H:%M:%S'

# 3. 获取日志级别
log_level_str = os.environ.get("VSC_LOG_LEVEL", "INFO").upper()
log_level = getattr(logging, log_level_str, logging.INFO)

# 4. 配置 logging (同时输出到控制台和文件)
logging.basicConfig(
    level=log_level,
    format=LOG_FORMAT,
    datefmt=DATE_FORMAT,
    handlers=[
        # 输出到控制台
        logging.StreamHandler(sys.stdout),
        # 输出到文件 (追加模式，UTF-8编码)
        logging.FileHandler(LOG_FILE, mode='a', encoding='utf-8')
    ]
)
