This GitHub is part of

• the Travis C++ Tutorial
• the Travis R Tutorial

The goal of this project is to have a clean Travis CI build, with specs:

• Build system: qmake
• C++ compiler: gcc
• C++ version: C++98
• Libraries: STL and Rcpp
• Code coverage: none
• Source: one single file, main.cpp

Less complex builds:

• Use STL only: travis_qmake_gcc_cpp98
• No Rcpp: travis_r_minimal

Architecture

This setup allows for independent C++ and R development. The C++ function do_magic_cpp is used by both the C++ project and the R package.

The C++ project

• domagic.pro: qmake project file
• main.cpp: contains the main function
• src/do_magic_cpp.h: header file with the do_magic_cpp function declaration
• src/do_magic_cpp.cpp: source file with the do_magic_cpp function definition

Note that the C++ code is not tested directly. The R package does this.

The R package

• domagic.Rproj: RStudio project file
• R/do_magic_r.R: defines the do_magic_r function, which calls the do_magic_cpp function
• /tests/testthat/test-do_magic.R: tests the do_magic_r function
