Changelog

v0.2.0 (beta-draft)

• Switch to spdlog/1.8.2 version in conanfile.
• Make a core logr class independent from traits class. This allows having the same base class (as a root) for logers based on traits.
• Make adjustments in cmake-scripts for packaging in conan-center-index.
• Rethinking write-to msg builder wrapped output. Introduce a wrapper for output in write-to message builders. This allows a message builder to receive out by reference and also by value. Thus it is a breaking change as previously using fmt::format_to(out, ...) doesn't work anymore. The following ways to use write-to message builders are possible:

    int x = make_int();
    std::string s = make_string();

    // All the logging is equivalent.

    // Out by value.
    logger.info( [&]( auto out ) {
        format_to( out, "Write-to message builder 1,  int:'{}', str: '{}'", x, s );
    } );
    logger.info( [&]( auto out ) {
        out.format_to( "Write-to message builder 2,  int:'{}', str: '{}'", x, s );
    } );
    logger.info( [&]( auto out ) {
        ::fmt::format_to( out.buf() "Write-to message builder 3,  int:'{}', str: '{}'", x, s );
    } );

    // Out by reference.
    logger.info( [&]( auto & out ) {
        format_to( out, "Write-to message builder 1,  int:'{}', str: '{}'", x, s );
    } );
    logger.info( [&]( auto & out ) {
        out.format_to( "Write-to message builder 2,  int:'{}', str: '{}'", x, s );
    } );
    logger.info( [&]( auto & out ) {
        ::fmt::format_to( out.buf() "Write-to message builder 3,  int:'{}', str: '{}'", x, s );
    } );
