logsys

A C++17 high performance log messages library.

You can use this libery in two different ways. As header-only library or as linkable library.

If you want to use the log library in another dynamic link libary, the linkable approach is the way to go. You will lose a little performance in exchange for the configurability of the log library in the main application that uses your library.

If you want to use the log library in a application project you can configure the log library completely at compile time and use the header-only approach.

Configuration

Usage

There are three functions you need to know:

• Log a message
• Log a message bound to a code block
• Log a message bound to a code block and catch any exceptions

Log a message

auto log(LogCallable&& message_producer)noexcept
-> void;

Log a message bound to a code block

auto log(LogCallable&& message_producer, Body&& body)
-> std::invoke_result_t< Body&& >;

Log a message bound to a code block and catch any exceptions

auto exception_catching_log(LogCallable&& message_producer, Body&& body)noexcept
-> std::conditional_t< std::is_void_v< std::invoke_result_t< Body&& > >,
    bool, optional< std::invoke_result_t< Body&& > > >
