levelStr() method from fcf::NTest::Logger class

const char* levelStr() const

void levelStr(const char* a_level)

Class: fcf::NTest::Logger

Package: fcfTest

File: test.hpp ( link_to_the_declaration_in_the_file , link_to_the_implementation_in_the_file )

Available from version: 1.0.4

Returns or sets a new log level value in string format

Data Return Mode:

Returns a pointer to a static string representing the current log level name

The levelStr() method converts the current fcf::NTest::ELogLevel of the logger into its human-readable string representation ("off", "ftl", "err", "wrn", "att", "log", "inf", "dbg", "trc", "all"). This is useful for logging the current verbosity level or for debugging the logger's state Data Recording Mode:

Sets the logger's verbosity threshold using a string identifier (e.g., "dbg", "err")

The levelStr method provides a convenient way to adjust the logging threshold at runtime using human-readable string identifiers. It internally maps the provided string to the corresponding fcf::NTest::ELogLevel enumeration

Arguments

cons char* a_level

- A pointer to a null-terminated string representing the desired log level. Valid identifiers include: "off", "ftl", "err", "wrn", "att", "log", "inf", "dbg", "trc", "all".

Result

const char*

- A pointer to a static string containing the level name

Example: Printing the current log level

fcf::NTest::logger().levelStr("dbg"); std::cout << "Current log level: " << fcf::NTest::logger().levelStr() << std::endl; // Output: Current log level: dbg

Example: Using within a custom prefix

fcf::NTest::logger().appendPrefixFunc([]( fcf::NTest::Logger& a_logger, fcf::NTest::Logger::MessageContext& a_messageContext) { return "[" + fcf::NTest::Logger::toLevelStr(a_messageContext.level) + "] "; }); fcf::NTest::log() << "Message with level in prefix." << std::endl;

Example: Simple recording

Switching the logger to debug mode using a string.

// Set level to Debug fcf::NTest::logger().levelStr("dbg"); fcf::NTest::dbg() << "Debug information is now visible." << std::endl;

Example: Integration with command-line logic

Commonly used when parsing configuration or command-line arguments to set verbosity

std::string userConfiguredLevel = "err"; fcf::NTest::logger().levelStr(userConfiguredLevel.c_str()); fcf::NTest::inf() << "This message will not be displayed."; fcf::NTest::err() << "This message will be displayed.";
