When defining configuration flags and options, use practices that ensure compatibility across different preprocessors and build environments. For macro-based configuration flags, use integer values (0/1) instead of boolean literals (true/false) to avoid preprocessor compatibility issues. Additionally, consider using runtime configuration mechanisms (like config objects or flags) instead of compile-time options when flexibility is needed.
Example of safer macro definitions:
// Safer - use integer values
#define PRINT_CHANGES 0
#define PRINT_SKIPS 0
// Or use properly defined constants
#define PRINT_CHANGES FALSE // where FALSE is defined as 0
// Instead of potentially problematic boolean literals
#define PRINT_CHANGES false // may cause preprocessor issues
For configuration mechanisms, prefer runtime configuration over compile-time when possible:
// Better - runtime configuration via config object
YGConfig config;
config.callMeasureCallbackOnAllNodes = true;
// Instead of compile-time only
#ifdef YOGA_CALL_MEASURE_CALLBACK_ON_ALL_NODES
This approach ensures better portability across different compilers and preprocessors while providing more flexibility for users of your code.
