Code Organization

• src: a single file to run example cases
• src/utils: some utility functions, including complexify.h and ind for arrays
• src/euler: currently the Roe solver, both primal and forward-mode differentiated version

Code Facilities

Use the TIME macro for timing things. Note that the macro returns an object which can be printed to an std::ostream.

using namespace Ticon;  // important!
std::cout << "elapsed time = " << TIME(setCourseAndSpeed(heading, speed)) << std::endl;

C++ Notes

• Put everything in a namespace
• Do not indent code inside a namespace
• Currently we use raw pointers rather than std::vector or std::array. This helps with Julia compatability, but should be reconsidered in the future (boundschecking would be nice).
• use auto whenever possible
• Always initialize data members of classes (especially those for which the default initialization is undefined)

CMake Notes

prefer target_* functions to *, ie. target_include_directories to include_directories. The idea is for each target to tell anyone who tries to link to it what they need to do (what library to link to, where the header files are found etc.) The top level CMakeLists.txt should use include to get the CMakeLists.txt of all components of the package.

Try to avoid lateral includes whenever possible. The main CMakeLists.txt should include every major component, and therefore make names available to each other.

CMAKE_CURRENT_LIST_DIR gives the directory of the current CMakeLists.txt file being run. Use this to set paths whenver possible.
