C++ Development

Building

# With Make
make

# With CMake
mkdir -p build && cd build
cmake ..
make

# Direct compilation
g++ -std=c++20 -Wall -Wextra -Werror -o program main.cpp

Testing

# With Makefile test target
make test

# With CTest (CMake)
cd build && ctest -V

# With Google Test
./build/tests/run_tests

Static Analysis

# Cppcheck
cppcheck --enable=all --std=c++20 --error-exitcode=1 src/

# Clang-tidy
clang-tidy src/*.cpp -- -std=c++20

# Clang static analyzer
scan-build make

Memory Checking

# Valgrind
valgrind --leak-check=full ./program

# AddressSanitizer
g++ -fsanitize=address -g -o program main.cpp

# UndefinedBehaviorSanitizer
g++ -fsanitize=undefined -g -o program main.cpp

Formatting

# Format with clang-format
clang-format -i src/*.cpp include/*.hpp

# Check without changing
clang-format --dry-run --Werror src/*.cpp include/*.hpp

TDD Cycle Commands

# RED: Write test, run to see it fail
cd build && make && ctest -V

# GREEN: Implement, run to see it pass
cd build && make && ctest -V

# REFACTOR: Clean up, ensure tests still pass
cd build && make clean && cmake .. && make && ctest -V
clang-format --dry-run --Werror src/*.cpp
