[Log4cplus-devel] Implementing %r in PatternLayout

[Malcolm S. <Mal...@Pr...>]

I've made the following modification for my needs (I need the %r option
supported).  I hope this (or something like it) can be added in a future
release.

 

PatternLayout.cpp

==============

 

// might want to use a new global - using this for now since it is
always initialized

namespace log4cplus

{

  extern helpers::Time TTCCLayout_time_base;

}

 

class RelativeTimeConverter : public PatternConverter  {

  public:

   RelativeTimeConverter(const FormattingInfo& info,

     const log4cplus::tstring& pattern);

   virtual log4cplus::tstring convert(const InternalLoggingEvent&
event);

 

private:

  log4cplus::tstring format;

};

 

 

////////////////////////////////////////////////

// RelativeTimeConverter methods:

////////////////////////////////////////////////

 

log4cplus::pattern::RelativeTimeConverter::RelativeTimeConverter

                                               (const FormattingInfo&
info,

                                                const
log4cplus::tstring& pattern)

: PatternConverter(info),

  format(pattern)

{

}

 

log4cplus::tstring

log4cplus::pattern::RelativeTimeConverter::convert

                                            (const InternalLoggingEvent&
event)

{

  log4cplus::helpers::Time const rel_time = event.getTimestamp () -
log4cplus::TTCCLayout_time_base;

  return rel_time.getFormattedTime(format, true);

}

 

 

// in void
log4cplus::pattern::PatternParser::finalizeConverter(log4cplus::tchar c)

case LOG4CPLUS_TEXT('r'):

    {

        log4cplus::tstring dOpt = extractOption();

        if(dOpt.empty ()) {

            dOpt = LOG4CPLUS_TEXT("%H:%M:%S:%q");

        }

        pc = new RelativeTimeConverter(formattingInfo, dOpt);

    }

    break;
