Basic Usage Example¶
This example demonstrates how to use siddiqsoft::ScopeTrace for scope tracing, nested scope timing (sub_scope()), info, trace, warning, and error logging, exception capture, and string formatting.
#include <iostream>
#include <thread>
#include <stdexcept>
#include <siddiqsoft/ScopeTrace.hpp>
void worker()
{
// Create nested scope from process singleton
auto scope = siddiqsoft::ScopeTrace::GetInstance().sub_scope("worker", siddiqsoft::LogLevel::trace);
scope.info("Worker starting task with ID={}", 42);
scope.trace("Low-level trace details for worker setup");
// Create a child nested scope ("worker/subtask") with warning threshold
auto sub = scope.sub_scope("subtask", siddiqsoft::LogLevel::warning);
std::this_thread::sleep_for(std::chrono::milliseconds(10));
sub.warn("Resource usage reached {}%", 85);
}
void perform_operation()
{
auto scope = siddiqsoft::ScopeTrace::GetInstance().sub_scope("perform_operation", siddiqsoft::LogLevel::trace);
worker();
try {
throw std::runtime_error("Simulated failure in sub-system");
}
catch (const std::exception& e) {
// Exception handler shortcut with custom formatted contextual details
scope.exp(e, "Error encountered during operation execution");
}
}
int main()
{
// Obtain process-wide singleton ScopeTrace instance
auto& scope = siddiqsoft::ScopeTrace::GetInstance("main", siddiqsoft::LogLevel::trace);
scope.info("Application initialization complete");
perform_operation();
return 0;
}
Sample Console Output & Coloring¶
Executing the example above outputs formatted log entries to std::cerr with dynamic depth spaces, ISO 8601 UTC timestamps, and ANSI colors:
