轻量级结构化日志库,提供彩色终端输出和上下文绑定

Project description

dictlog

English

structlog 启发的轻量级结构化日志库,提供彩色终端输出和上下文绑定。

相比 structlog,dictlog 的方法签名完全标注了类型,编辑器可以正常补全和提示。

功能肯定没有 structlog 强大,但是终于不用再看编辑器的错误提示了。

由于是基于系统库 logging 实现,使用上完全兼容。

Demo

特性

  • 结构化日志 + key-value 上下文绑定(bind/unbind
  • 彩色终端输出,紧凑格式
  • 支持 6 种日志级别:TRACE < DEBUG < INFO < WARNING < ERROR < CRITICAL
  • 支持子 logger(用 . 分隔名称)
  • exception() 方法自动附加异常堆栈
  • 开箱即用,零配置
  • 完整的类型标注,编辑器友好

安装

dictlog 在 PyPI 上已经有别人申请了,但是我也没想到更好的名字,所以就先通过 git 安装吧。

pip install git+https://github.com/uiautodev/dictlog.git@x.x.x
# 或使用 uv
uv add git+https://github.com/uiautodev/dictlog.git@x.x.x

要求 Python >= 3.9。

使用

import dictlog

# 基本用法
log = dictlog.get_logger("myapp")
# 调整日志级别,与 logging.DEBUG 等价,默认是 WARNING
log.level = dictlog.DEBUG

# 支持的日志级别:TRACE(5) < DEBUG(10) < INFO(20) < WARNING(30) < ERROR(40) < CRITICAL(50)
log.trace("detailed debug info", user_id=123)  # 最详细的调试信息
log.debug("debug message", port=8080)
log.info("server started", port=8080)

# 绑定上下文,后续调用自动携带
log = log.bind(user="alice")
log.info("user logged in")          # 自带 user=alice
log = log.unbind("user")
log.info("context removed")         # 不再包含 user

dictlog 是如何调用 logging 的

log = dictlog.get_logger("foo", name=123)
log.info("hello")

等价于

root_log = logging.getLogger("dictlog")
if not root_log.handlers:
    handler = logging.StreamHandler()
    handler.setFormatter(_formatter)  # ColorFormatter
    root_log.addHandler(handler)
log = logging.getLogger("dictlog.foo")
log.info("hello %s", "name=123")

如果不想使用 dictlog. 开头,可以通过修改 dictlog._ROOT_NAME 实现

开发

# 安装依赖
uv sync

# 运行 pre-commit hooks
uv run pre-commit run --all-files

# 运行示例
uv run dictlog.py
