#include <Rcpp.h>

// thanks to Simon for the macro magic
// problem #1: R internals uses "private" and "class" as 
//             member names. So a C++ compiler is confused
//             when we include Connections.h
//             this workaround uses the preprocessor to rename
//             class as class_name and private as private_ptr
#define class class_name
#define private private_ptr

Log Message Normalization Module

Module Name: mmjsonparse

Description:

This module provides support for parsing structured log messages that follow the CEE/lumberjack spec. The so-called "CEE cookie" is checked and, if present, the JSON-encoded structured message content is parsed. The properties are than available as original message properties.

Sample:

nicebread

These code snippets have been tested on R 3.1.0 and Mac OS 10.9.3. They presumably do *not* work on R 2.X!

## Enter these commands in the Mac OS Terminal

# use faster vecLib library
cd /Library/Frameworks/R.framework/Resources/lib
ln -sf  /System/Library/Frameworks/Accelerate.framework/Frameworks/vecLib.framework/Versions/Current/libBLAS.dylib libRblas.dylib

# return to default settings
cd /Library/Frameworks/R.framework/Resources/lib
