A useful logging library for Python
Project description
NsparkleLog日志库
描述
NsparkleLog 是一个高性能的日志库,设计之初就注重性能和多线程支持。与其他日志库相比,NsparkleLog 在处理大量日志条目时表现出色。
性能对比
我们对比了 NsparkleLog 和 Loguru 的性能,结果显示:
- NsparkleLog:
- 总耗时:2.77 秒
- 平均每条日志耗时:0.000277 秒
- Loguru:
- 总耗时:4.06 秒
- 平均每条日志耗时:0.000406 秒
这意味着 NsparkleLog 的性能比 Loguru 快约 36%。
主要特点
- 多线程支持:使用队列和线程高效处理并发日志记录
- 自定义锁机制:确保线程安全的同时最大化性能
- 从底层实现:避免对第三方库的依赖,进一步优化性能
安装
pip install NsparkleLog
测试质疑
- 如果您对测试结果感到质疑,可以自己修改下列测试脚本
from NsparkleLog import logger as NsparkleLogger
from loguru import logger as LoguruLogger
import time
# 测试参数
num_messages = 10000
test_message = "This is a test log message."
# 测试 NsparkleLog
nsparkle_times = []
for i in range(num_messages):
start_time = time.time()
NsparkleLogger.info(test_message)
end_time = time.time()
nsparkle_times.append(end_time - start_time)
nsparkle_duration = sum(nsparkle_times)
nsparkle_avg_time = nsparkle_duration / num_messages
# 测试 Loguru
loguru_times = []
for i in range(num_messages):
start_time = time.time()
LoguruLogger.info(test_message)
end_time = time.time()
loguru_times.append(end_time - start_time)
loguru_duration = sum(loguru_times)
loguru_avg_time = loguru_duration / num_messages
# 输出结果
print(f"NsparkleLog total duration: {nsparkle_duration:.2f} seconds")
print(f"NsparkleLog average time per message: {nsparkle_avg_time:.6f} seconds")
print(f"Loguru total duration: {loguru_duration:.2f} seconds")
print(f"Loguru average time per message: {loguru_avg_time:.6f} seconds")

更新了可以自定义渲染日志字段消息的功能,美化显示
- 用法
from NsparkleLog import LogManager , Levels , StreamHandler , Formatter
logBodyColor = {
"localtime": "cyan",
"ProcessName": "green",
"threadName": "yellow",
"name": "blue",
"funcName": "magenta",
"filename": "cyan",
"lineno": "cyan",
"msecs": "cyan",
}
consoleHanlder = StreamHandler()
console_fmt = Formatter(colorMode=True)
console_fmt.configuateColor(logBodyColor,True)
consoleHanlder.setFormatter(console_fmt)
LogManager.config(
handlers=[consoleHanlder],
level=Levels.TRACE, # type: ignore
colorMode=True
)
logger = LogManager.getLogger('test')
logger.info('test')

修复颜色渲染bug
[2024/6/26 21:32]
更新了HTML标签字体渲染
- 用法如下,这里用 cyan 作为示例
from NsparkleLog import logger
logger.trace("<cyan>Hello World</cyan>")
logger.debug("<cyan>Hello World</cyan>")
logger.info("<cyan>Hello World</cyan>")
logger.warning("<cyan>Hello World</cyan>")
logger.error("<cyan>Hello World</cyan>")
logger.fatal("<cyan>Hello World</cyan>")
- 你也可以用 Color 类来查看所有自带的颜色
from NsparkleLog import Color
print(Color.GetAvaliableColor())
- 当然了,也允许你动态的添加颜色
from NsparkleLog import Color
Color.regColor(50,"test_color")
- 如果你有自定义的等级想渲染注册好的颜色或者使用原来的颜色,不要忘了映射噢~
from NsparkleLog import LevelColor , logger
LOGG = 25
logger.addNewLevel("LOGG",LOGG)
LevelColor.mapLevelToColor(LOGG,"cyan")
logger.log(LOGG,"hello world")
[2024/6/22 15:26]
更新了NsparkleLogHandler类用于转发logging日志消息到NsparkleLog日志库
- 用法如下
from NsparkleLog import NsparkleLogHandler
import logging
logger = logging.getLogger("test")
handler = NsparkleLogHandler()
logger.addHandler(handler)
logger.setLevel(logging.DEBUG)
logger.debug("debug")
logger.info("info")
logger.warning("warning")
logger.error("error")
logger.critical("critical")
[2024/6/21 17:26]
更新了一个config接口用于配置日志
- 用法
from NsparkleLog import LogManager , Levels , StreamHandler
LogManager.config(
handlers=[StreamHandler()],
level=Levels.TRACE,
colorMode=True,
)
logger = LogManager.GetLogger("test")
logger.trace("Hello, World!")
logger.debug("Hello, World!")
logger.info("Hello, World!")
logger.warning("Hello, World!")
logger.error("Hello, World!")
logger.fatal("Hello, World!")
[2024/6/5 22:14]
更新了类似loguru的catch装饰器
- 现在可以用@logger.catch来捕获函数中的异常并打印堆栈
from NsparkleLog import logger
@logger.catch
def test():
raise Exception("this is a test exception")
test()
output:
2024-06-05 22:13:03.793 | ERROR | MainProcess.MainThread | main.wrapper | NsparkleLog\core\_logger.py:60 - 发生异常:
An Fatal Error has occurred: Exception: This is an exception
Traceback (most recent call last):
at wrapper in (f:\python_play\NsparkleLog\NsparkleLog\core\_logger.py:58)
at test in (f:\python_play\NsparkleLog\asynctest.py:12)
[2024/6/4 21:52]
更新trace方法
- trace方法现在支持withStackTrace参数,如果为True,则包含堆栈跟踪,否则只记录信息
from NsparkleLog import logger
logger.trace("This is a trace message",withStackTrace=True)
output:
2024-06-04 21:50:44.840 | TRACE | MainProcess.MainThread | main.<module> | asynctest.py:3 - This is a trace message
Stack Trace:
at <module> in (f:\python_play\NsparkleLog\asynctest.py:3)
[2024/6/2 14:01]
更新了logger.exception接口
from NsparkleLog import logger
try:
raise Exception
except Exception as e:
logger.exception(e)
[2024/6/1 18:51]
完善多线程,多进程,异步的安全
[2024/5/30 21:33]
日志库不用再需要显示调用close方法来释放资源,主线程退出后会自动释放资源
更新了setLevel接口用于设置日志级别过滤
- 同时修复了一个addNewLevel可能会覆盖自己日志库定义等级的bug
from NsparkleLog import logger
from NsparkleLog.core._level import Levels
logger.setLevel(Levels.INFO)
logger.trace("Trace message") # 过滤
logger.debug("Debug message") # 过滤
logger.info("Info message")
logger.warning("Warning message")
logger.error("Error message")
logger.fatal("fatal message")
添加了addNewLevel方法来提升灵活性
from NsparkleLog import logger
TEST = 25
logger.addNewLevel("test", TEST, 91, "bright_magenta")
logger.log(TEST, "test")
FileHandler用法
from NsparkleLog import logger
from NsparkleLog.core._handler import FileHandler
from NsparkleLog.core._formatter import Formatter
filehandler = FileHandler(filename="test.log", mode="a+")
fmts = Formatter() #懒得设置格式直接这样也行
filehandler.setFormatter(fmts)
logger.addHandler(filehandler)
logger.trace("Trace message")
logger.debug("Debug message")
logger.info("Info message")
logger.warning("Warning message")
logger.error("Error message")
logger.fatal("fatal message")
