[Log4cplus-devel] Header line for file appenders

[Steve H. <sha...@mi...>]

Hello all,

I have recently run into a situation in which it would have been really convenient if the file appenders had some way to add a header line to the top of each file.  I don't mind doing the coding for this, but first wanted to throw the idea out there to see if someone else may have a better idea for implementation.

My plan was to simply add an attribute to the file appenders named something like "FileHeader" which would contain a string.  That string would be inserted as the first line in each file.  For example:

log4cplus.temperatureLogger=DEBUG, A2
log4cplus.appender.A2=log4cplus::DailyRollingFileAppender
log4cplus.appender.A2.File=log/temperature
log4cplus.appender.A2.layout=log4cplus::PatternLayout
log4cplus.appender.A2.Schedule=DAILY
log4cplus.appender.A2.MaxBackupIndex=2
log4cplus.appender.A2.FileHeader=Date Temperature1 Setpoint1 Temperature2 Setpoint2%n
log4cplus.appender.A2.layout.ConversionPattern=%D{%Y-%m-%d %H:%M:%S.%q}  %m%n

Or should this be implemented in the layout?


Thoughts?
