Member Function Documentation

◆ configure_from_env()

void ncorr::log::Logger::configure_from_env ( )

Apply NCORR_LOG_LEVEL / NCORR_LOG_FILE / NCORR_LOG_CONSOLE.

Runs once automatically on first use; calling again re-applies them.

Definition at line 147 of file log.cpp.

◆ console_level()

Level ncorr::log::Logger::console_level ( ) const

Definition at line 172 of file log.cpp.

◆ enabled()

bool ncorr::log::Logger::enabled ( Level l )

True if a message at l would reach any sink.

Use to guard expensive message construction in hot loops.

Definition at line 200 of file log.cpp.

◆ file_level()

Level ncorr::log::Logger::file_level ( ) const

Definition at line 177 of file log.cpp.

◆ instance()

Logger & ncorr::log::Logger::instance ( )

static

Definition at line 131 of file log.cpp.

◆ set_console_enabled()

void ncorr::log::Logger::set_console_enabled ( bool on )

Enable or disable console output entirely.

Definition at line 190 of file log.cpp.

◆ set_console_level()

void ncorr::log::Logger::set_console_level ( Level l )

Definition at line 162 of file log.cpp.

◆ set_file()

bool ncorr::log::Logger::set_file ( const std::string & path )

Open (or replace) the file sink.

An empty path closes the file sink.

Returns: false if path could not be opened (file sink left closed).

Definition at line 182 of file log.cpp.

◆ set_file_level()

void ncorr::log::Logger::set_file_level ( Level l )

Definition at line 167 of file log.cpp.

◆ set_verbose_format()

void ncorr::log::Logger::set_verbose_format ( bool on )

Include timestamp + source location in console output too (the file sink always includes them).

Off by default to keep the console readable.

Definition at line 195 of file log.cpp.

◆ write()

void ncorr::log::Logger::write	(	Level	l,
		const char *	file,
		int	line,
		const std::string &	msg
	)

Emit a fully-formed message (trailing newlines are trimmed) at l.
