36-50: Review thescope_logstructure for potential improvements.The
scope_logstructure uses rvalue references for its constructor parameters, which is unusual and might lead to confusion or errors if misused. Typically, structures like this should use const references unless there is a specific need to consume the passed arguments.Consider changing the constructor to take const references instead of rvalue references to avoid unnecessary complexity and potential bugs:
- scope_log(int&& i_, std::string&& str) + scope_log(const int& i_, const std::string& str) : i{i_} , key{str} { if (i <= LOG_LEVEL) { PHARE_LOG_START(i, key.c_str()); } }This change makes the code more robust by preventing unintended modifications to the original variables passed to the constructor.

1-1: Address TODO comments and review potential performance implications.While the code is generally well-structured and uses modern C++ practices, there are TODO comments that suggest incomplete areas that might need further attention. Additionally, considering the complexity of the operations within the
initializemethod, it would be beneficial to review the performance implications, especially in terms of memory and computational efficiency.Would you like me to help in addressing these TODO comments or perform a more detailed performance analysis?

PHARE_LOG_LINE_STRis a positive change, aligning with the objectives to reduce console output verbosity and improve logging mechanisms.

Ensure macro definitions are consistent across build configurations.
The macro PHARE_LOG_LINE_SS is defined differently based on the build configuration. It's important to ensure that the macro behaves consistently or is disabled appropriately across different configurations to prevent runtime errors and maintain code clarity.
Verify that the macro is either consistently defined or appropriately disabled across all configurations. If disabling is the choice, ensure that it does not lead to any unresolved references during compilation in release mode.

this is so we do not print lines during release mode with -DNDEBUG

@PhilipDeegan, thank you for the clarification. The conditional definition of the macro makes sense to avoid unnecessary logging in release mode with -DNDEBUG. This approach is indeed appropriate for optimizing performance and reducing output clutter in production environments.

Refactor the macro parameter for consistency.
The macro PHARE_LOG_LINE_SS uses s as a parameter, which is inconsistent with the change noted in the alterations summary that suggests it should be str. This inconsistency can lead to confusion and potential errors in macro usage.
Consider renaming the parameter to match the intended usage and documentation:
-#define PHARE_LOG_LINE_SS(s) PHARE_LOG_LINE_STR((std::stringstream{} << s).str());
+#define PHARE_LOG_LINE_SS(str) PHARE_LOG_LINE_STR((std::stringstream{} << str).str());Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

because it's a macro, it would not be advisable to use the input parameter str as it might conflict with the stringstream::str() call
There was a problem hiding this comment.
@PhilipDeegan, you're absolutely right. Using str as a parameter name in the macro could indeed lead to conflicts with the stringstream::str() method. Keeping the parameter name as s is the best approach to avoid any potential issues. Thanks for the clarification!
