Features:

• 日志服务模块化，每个模块可以共享使用
• 日志模块与输出模块相互独立，可以是N:N的关系(比如，一个日志模块可以输出到独立的文件中)
• 文件输出模式可以按照轮转、周期、文件大小来控制输出日志的数量
• 日志模块之间可以是继承关系，采用.来确定关系，一些模块属性也会从父模块中继承到子模块中
• 日志记录输出类型有多种，详见root.__type__, 各类型之间是"或"的关系，并能随着继承关系传递,到子模块
• 配置文件可以实时修改，即时生效，无需重启应用程序
• 支持终端彩色输出
• 可根据函数调用栈分级输出日志，方便查看函数的调用次序

配置文件模板

[global]
# Global configure.
# Logger accesses this config-file per <check_config_interval>,
# that will reload this config-file that be modified and validate
# the new strategy.
# The 'interval' is by Second Unit if the last charactor is 's/S',
# on 'm/M' by minute, others are not supported(default is 's').
check_config_interval = 5s

[screen_output]
# ouput configure.
# Support : STDOUT,FILES,SHUTDOWN
type = shutdown

[file_output]
# ouput configure.
# Support : STDOUT,FILES,SHUTDOWN
type = FILES

# Log file name
name = http
dir = ./log

# Single file size.
# The 'size' is by MBytes Unit if the last charactor is 'M',
# on 'K' by KBytes, others do not supported(default is 'M').
# If value is ''(null), the file size is unlimited.
# Default value is 1M
single_file_size = 2M

# Max index of rolloever.
# For example : <rolloever> = 5
# 2008-08-08.log(current), 2008-08-08.log.1, 2008-08-08.log.2,
# 2008-08-08.log.3, 2008-08-08.log.4, 2008-08-08.log.5(lasted).
# Default value is 0
rolloever = 5

# Support : Seconds.
# How long create a new log file.
# If value is ''(null), this abbtribute will be disable.
# Default value is 0

[modules]
##
# Support : ALLS|TRACE|DEBUG|WNING|ERROR|RINFO|FATAL|SHUTDOWN
# Log type is hereditable, all of modules inherit from <root>
# If value is ''(null), the root has not strategy.
# Don't delete this attribute !!!.
root.__type__ = ERROR|RINFO
# Example :
# http_server = TRACE|RINFO      # actually is root.http_server
# http_server.request = DEBUG
# ftp_server.download = RINFO|FATAL
# If you want to close the logger of this module, you must type `SHUTDOWN'
# and not ''.
# ftp_server.upload = SHUTDOWN
# If value is ''(null), the module's configure inherits from its parent

# Mode of log-msg be output
# If value is ''(null), the output default set to `NULL'
root.__output__ = file_output

# Max length of one log record(not include format string!!), Bytes Unit
# Default value is 511

# user's log modules
# example:
root.main.__type__ = DEBUG|TRACE
