#include <console_trace_listener.h>

Definition

Directs tracing or debugging output to either the standard output or the standard error stream.

Namespace: xtd::diagnostics

Library: xtd.core

Examples: The following example shows how to use xtd::diagnostics::console_trace_listener class.
#define DEBUG // Force debug mode even if example is builded in release.
#include <memory>
#include <thread>
#include <xtd/xtd>
using namespace std;
using namespace std::literals;
using namespace std::this_thread;
using namespace xtd::diagnostics;
int main() {
debug::listeners({make_shared<console_trace_listener>()});
debug::write_line("Begin");
debug::indent();
for (auto step = 1; step <= 10; step++) {
debug::write_line("working step {}...", step);
sleep_for(300ms);
}
debug::unindent();
debug::write_line("End");
}
// This code produces the following output :
//
// Begin
// working step 1...
// working step 2...
// working step 3...
// working step 4...
// working step 5...
// working step 6...
// working step 7...
// working step 8...
// working step 9...
// working step 10...
// End

◆ console_trace_listener() [1/2]

xtd::diagnostics::console_trace_listener::console_trace_listener ( )

Initializes a new instance of the xtd::diagnostics::console_trace_listener class with trace output written to the standard output stream.

Remarks: This constructor initializes a xtd::diagnostics::console_trace_listener object to write messages to either the std::cout or the std::cerr stream. Its xtd::diagnostics:::console_trace_listener::name property is initialized to an empty string ("").

◆ console_trace_listener() [2/2]

xtd::diagnostics::console_trace_listener::console_trace_listener ( bool use_error_stream )

Initializes a new instance of the xtd::diagnostics::console_trace_listener class with an option to write trace output to the standard output stream or the standard error stream.

Parameters

use_error_stream true to write tracing and debugging output to the standard error stream; false to write tracing and debugging output to the standard output stream.

Remarks: This constructor initializes a xtd::diagnostics::console_trace_listener object to write messages to either the std::cout or the std::cerr stream. Its xtd::diagnostics::console_trace_listener::name property is initialized to an empty string ("").
