Project Overview
cuber is a simple cube timer application.
Build System
- Generator: Ninja
- CMake minimum: 3.21
- C++ standard: C++23
Commands
cmake -S . -B build -GNinja
ninja -C build
./build/cuber
Dependencies
Dependencies are managed via custom Find*.cmake scripts in deps/.
These scripts use FetchContent under the hood to download and build
libraries automatically. They are shared with the nerv project.
To add a new dependency:
- Copy the corresponding
Find<name>.cmakefromnerv/deps/ - Add
find_package(<name> REQUIRED)toCMakeLists.txt - Link with
<name>::<name>intarget_link_libraries()
CMake Module Path
deps/ is added to CMAKE_MODULE_PATH so find_package() resolves
to the custom scripts instead of system-installed packages.
Coding Conventions
- Language: C++23
- Trailing return type for function signatures
- 4-space indentation
- No semicolons after closing braces for namespaces/classes
autofor obvious types (e.g.auto main(...) -> int)<>includes only for system headers (std, OS, etc.)""includes for third-party dependencies (e.g.fmt,nlohmann/json)- Include order:
- C++ standard library headers (
<chrono>,<vector>, etc.) - (blank line)
- C standard library headers (
<stdlib.h>,<string.h>, etc.) - (blank line)
- OS-specific headers (Windows API, POSIX, etc.)
- (blank line)
- Third-party dependencies (
"fmt/core.h", etc.) - (blank line)
- Local/project headers
- C++ standard library headers (
Shell Scripts
- Always use
#!/bin/shshebang for shell scripts - Scripts must be POSIX compliant (no bashisms)
- When providing commands to users:
- Windows/PowerShell: use
`for line continuation - Unix/Linux/macOS: use
\for line continuation
- Windows/PowerShell: use

Platform Support
The nerv project supports Windows, Linux, Emscripten, and Android via
Platform.cmake and Flags.cmake. These can be added to cuber/deps/
when cross-platform support is needed.
