RcppLogger

Simple lightweight header-only logging framework for Rcpp. Lets you chain stuff together using the standard << notation. Not threadsafe.

Usage

After installing the package,

#install_package("devtools")
devtools::install_github("njanetos/RcppLogger")

include the header file RcppLogger.h somewhere.

If you want to use RcppLogger as part of a package, put the line

LinkingTo: RcppLogger

in your DESCRIPTION and then include the header file in your C++ code using #include <RcppLogger.h>.

Here is an example of how to use the logger:

#include <RcppLogger.h>
using namespace RcppLogger;
logger logg(ALL);

logg.info() << "General information";
logg.warning() << "This is " << "a warning.";
logg.error() << "This is an error.";

logg.configure(QUIET);

logg.info() << "This won't be displayed.";
logg.warning() << "Neither will this.";
logg.error() << "This also won't be displayed.";

logg.configure(WARNING);

logg.info() << "This won't be displayed";
logg.warning() << "This will.";
logg.error() << "Errors will be displayed as well.";

Output:

[INFO] General information
[WARNING] This is a warning.
[ERROR] This is an error.
[WARNING] This will.
[ERROR] Errors will be displayed as well.
