In this example, `submodule` is considered a sublogger of `module` and `app` the parent of `module`. A sublogger implicitly inherits all sinks and the log level of the parent, unless explicitly configured otherwise. + +The hierarchical tree of loggers always contains the root logger at the top. The root logger itself does not have a parent, nor a name. It can be accessed via `l3pp::Logging::getRootLogger()`. + +Each logger is assigned a log level, or is configured to inherit the log level of the parent (with the special log level `l3pp::LogLevel::INHERIT`). Note that the root logger cannot inherit a log level. Any log entry with a lower level is filtered out and will not be logged. + +A logger can also be assigned one or more sinks. By default, a logger will log to both the sinks of its parent, as well as its own sinks. Should a logger only use it own sinks, it should be set to non-additive (using `Logger::setAdditive(false)`). + +Sinks +----- +A sink provides an output for loggers. Loggers may define multiple sinks, and sinks may be shared between loggers. Sinks are associated with a formatter and a log level. The log level specifies the minimum level of a message for it to be output (independent of the log level of a logger), and by default permits all log messages. A formatter formats the log messages before being output. By default, a simple formatter is used which prints the log level, message and a newline, but other formatters can be specified. + +Formatters +----- +A formatter shapes a log message before being sent to its final destination. A non-configurable simple formatter exists, as well as a template-based formatter. The latter specifies the format of a message by means of its template arguments, see `l3pp::makeTemplateFormatter`. + + +Basic Usage +===== + +A logger object can be accessed via `l3pp::Logger::getLogger()` or `l3pp::Logger::getRootLogger()`. By default, the root logger does not output anywhere. Therefore, a sink should be added. An initial configuration may look like this: + + l3pp::Logger::initialize(); + l3pp::SinkPtr sink = log4carl::StreamSink::create(std::clog); + l3pp::Logger::getRootLogger()->addSink(sink); + l3pp::Logger::getRootLogger()->setLevel(log4carl::LogLevel::INFO); + +In this demo, a single sink is created that passes log messages to the standard logging stream `std::clog`. All messages must have at least level `LVL_INFO` before being printed. + +The actual logging is performed using a handful of macros. +These macros + + +Considerations +===== + +Performance +----- +While the use of hierarchical loggers and multiple sinks with associated formatters gives a lot of flexibility, it comes at a certain price. As the configuration is done at runtime (and may even change at runtime), the question whether a certain message is printed can only be answered at runtime. Therefore, every message, whether you will ever see it or not, has to pass through the logger and cost runtime. + +To mitigate this, we suggest the following: + +Create a preprocessor flag (like `ENABLE_LOGGING`) and define your own set of logging macros. +If this flag is defined, make your macros forward to the `L3PP_LOG_*` macros. +If this flag is not defined, make your macros do nothing. + + +Multiple usages in the same project +----- +Assume you have an application that uses L3++ for logging as well as some other library that also uses L3++. +L3++ will play nicely in this scenario (partly, it was designed for this case). + +However, you should take care of a few things: +* Colliding loggers: Prefix your loggers with some unique prefix. +* Colliding macros: If you implement the aforementioned `ENABLE_LOGGING` macro, prefix your macros with your project name. Otherwise, these macros will collide. + + +Implementation Details +===== + +Sinks +----- +A sink is a class that provides some `log` method. Any class that inherits from `l3pp::Sink` can be used. + +As of now, two implementations are available: +* FileSink: Writes to a output file. +* StreamSink: Writes to any given `std::ostream`, for example to `std::cout`. + +Formatters +----- +A formatter is a functor that given a log entry, provides a formatted string. The base class `Formatter` provides some very simple formatting, whereas `TemplateFormatter` provides more control over the shape. Internally, a `TemplateFormatter` streams its arguments to a stream before constructing the string. The special types `FieldStr` and `TimeStr` can be used to format particular attributes of a log entry. diff --git a/resources/3rdparty/l3pp/formatter.h b/resources/3rdparty/l3pp/formatter.h new file mode 100644 index 000000000..846a8d5e2 --- /dev/null +++ b/resources/3rdparty/l3pp/formatter.h @@ -0,0 +1,158 @@ +/** + * @file formatter.h + * @author Harold Bruintjes + * + * Define the Formatter class, used to format output of a sink + */ + +#pragma once + +#include +#include + +namespace l3pp { + +/** + * Formats a log messages.
