Work on LOGCXX-515 started by Robert Middleton.
-----------------------------------------------
> Add macros to utilize libfmt formatting for messages
> ----------------------------------------------------
>
> Key: LOGCXX-515
> URL: https://issues.apache.org/jira/browse/LOGCXX-515
> Project: Log4cxx
> Issue Type: New Feature
> Reporter: Robert Middleton
> Assignee: Robert Middleton
> Priority: Major
> Fix For: 0.12.0
>
>
> Create macros that use fmt::format to create the log message.
>
> The prototype looks like this:
> {code:java}
> #define LOG4CXX_INFO_FMT(logger, ...) do { \
> if (logger->isInfoEnabled()) {\
> logger->forcedLog(::log4cxx::Level::getInfo(),
> fmt::format( __VA_ARGS__ ), LOG4CXX_LOCATION); }} while (0)
> {code}
> Usage:
> {code:java}
> LOG4CXX_INFO_FMT( logger, "This is a message that has some kind of {}
> information in it", "useful" );
> {code}
> This is slightly faster at runtime than using the MessageBuffer class with
> operator<< all the time, and much clearer. Conveniently, the coloring
> provided by libfmt also shows up on the output.
>
> is there a better name than LOG4CXX_INFO_FMT?
