Boiler plate for C++ projects

This is a boiler plate for C++ projects. What you get:

Sources, headers and mains separated in distinct folders
Access to Google Tests
Use of CMake for much easier compiling
Continuous testing with Travis-CI, with support for C++17.
Code coverage reports, including automatic upload to Coveralls.io
Code documentation with Doxygen

Structure

.
├── CMakeLists.txt
├── app
│   └── main.cpp
├── include
│   ├── example.h
│   └── exampleConfig.h.in
├── src
│   └── example.cpp
└── tests
    ├── dummy.cpp
    └── main.cpp

Sources go in src/, header files in include/, main programs in app/, and tests go in tests/ (compiled to unit_tests.x by default).

If you add a new executable, say app/hello.cpp, you only need to add the following three lines to CMakeLists.txt:

add_executable(hello.x app/hello.cpp)   # Name of exec. and location of file.
add_dependencies(hello.x engine)        # engine is the library built from src/*.cpp
target_link_libraries(hello.x engine)   # Link the executable to the 'engine'.

You can find the example that builds the example in app/main.cpp under the Build section in CMakeLists.txt. If the executable you made does not use the library in src/, then only the first line is needed.

Building

Build by making a build directory (i.e. build/), run cmake in that dir, and then use make to build the desired target.

Example:

> mkdir build && cd build
> cmake .. -DCMAKE_BUILD_TYPE=[Debug | Coverage | Release]
> make
> ./main.x
> make gtest     # Makes and runs the tests.
> make coverage  # Generate a coverage report.
> make doc       # Generate html documentation.

.gitignore

The .gitignore file is a copy of the Github C++.gitignore file, with the addition of ignoring the build directory (build/).

Services

If repository is activated with Travis-CI, then unit tests will be built and executed on each commit.

If repository is activated with Coveralls, then deployment to Travis will also calculate code coverage and upload this to Coveralls.io.

Setup

When starting a new project, you probably don't want the history of this repository. To start fresh you can use the setup script as follows:

> git clone https://github.com/bsamseth/cpp-project  # Or use ssh-link if you like.
> cd cpp-project
> sh setup.sh
