Code Guidelines

Always investigate before making changes. Add logging and test cases as needed.
Write test cases (both end-to-end and unit) to demonstrate bugs before fixing those bugs.
Avoid duplicating work. Put shared utilities in the main /src folder.
Comment well, but don't overcomment. Assume the reader knows C++ and can read the code.
Split code into multiple files. Avoid long files if possible.
Always update the relevant documentation in the /docs folder. Create new documentation if need be.

Commands

Build with cmake --build build.
Run the tests with build/Tests.
Run a file in the project's programming language with build/CLI -t <file>. Add -e for verbose mode.
