Each revision brings new features and improvements which make our lives as engineers easier and our code more expressive. Although C++23 is a smaller update than 20, partially due to the pandemic, there\u2019s still plenty of new features to unwrap and get stuck into, let\u2019s take a look at some of these.<\/p>\n<h3>Features<\/h3>\n<h2><span style=\"font-weight: 400;\">Deducing this<\/span><\/h2>\n<p>In C++ non-static member functions have an implicit \u201cthis\u201d argument, which points to the invoking object. The \u201cdeducing this\u201d paper extends the language to allow \u201cthis\u201d to be explicitly declared in the method signature.<\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"cpp\">\/\/ before\r\nclass Foo\r\n{\r\npublic:\r\n    void doSomething()\r\n    {\r\n        std::cout &lt;&lt; this-&gt;mValue &lt;&lt; 'n';\r\n    }\r\nprivate:\r\n    int mValue;\r\n};\r\n \r\n\/\/ after\r\nclass Foo\r\n{\r\npublic:\r\n    void doSomething(this Foo const&amp; self, int i);\r\n    {\r\n        std::cout &lt;&lt; self.mValue &lt;&lt; 'n';\r\n    }\r\nprivate:\r\n    int mValue;\r\n};\r\n<\/pre>\n<p><span style=\"font-weight: 400;\">By making the \u201c<\/span><i><span style=\"font-weight: 400;\">this\u201d <\/span><\/i><span style=\"font-weight: 400;\">explicit the member method can deduce the value category of the invoking expression. So the method can tell if it\u2019s being called on an l-value or r-value and if it is const or volatile.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The main use case for this is code de-duplication, the <\/span><a href=\"https:\/\/www.open-std.org\/jtc1\/sc22\/wg21\/docs\/papers\/2021\/p0847r6.html\"><span style=\"font-weight: 400;\">paper<\/span><\/a><span style=\"font-weight: 400;\"> is well worth a read and showcases its advantages. However there is one use case that is directly applicable to the Maven code base, the ability to remove the Curious Recurring Template Pattern (CRTP).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The following code snippet is a simplified version of a base class in our serialisation library.<\/span><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"cpp\">template&lt;typename DerivedType&gt;\r\nclass WriterBase\r\n{\r\npublic:\r\n    template&lt;concepts::String T&gt;\r\n    void serialize(T const&amp; value)\r\n    {\r\n        derived().writeString(value.data(), value.size());\r\n    }\r\n \r\nprivate:\r\n    DerivedType&amp; derived() { return *static_cast&lt;DerivedType*&gt;(this); }\r\n    DerivedType const&amp; derived() const { return *static_cast&lt;DerivedType const*&gt;(this); }\r\n};\r\n \r\nclass SimpleWriter : public WriterBase&lt;SimpleWriter&gt;\r\n{\r\npublic:\r\n    void write(char const *data, std::size_t size)\r\n{\r\n    \/\/ do actual writing here\r\n}\r\n \r\n};\r\n<\/pre>\n<p><span style=\"font-weight: 400;\">But with explicit access to this:<\/span><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"cpp\">class WriterBase\r\n{\r\npublic:\r\n    template &lt;typename Self, typename T&gt;\r\n    void serialize(this Self &amp;&amp;self, T const&amp; value)\r\n    {\r\n        self.writeString(value.data(), value.size());\r\n    }\r\n};\r\n \r\nclass SimpleWriter : public WriterBase\r\n{\r\npublic:\r\n    void write(char const *data, std::size_t size)\r\n    {\r\n        \/\/ do actual writing here\r\n    }\r\n \r\n};\r\n<\/pre>\n<p><span style=\"font-weight: 400;\">It may not seem like a big change but:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">We\u2019ve removed the need for all the casting with the derived() methods<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">We have access to the derived type directly in the method that needs it<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">We\u2019ve removed the need to template WriterBase<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">At Maven we pride ourselves in the way we leverage templates to solve problems generically and also to achieve better runtime performance. The cost we pay is higher compile times. So any reduction in templated code (without sacrificing performance) is welcome.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Monadic operations on std::optional<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Std::optional is an important vocabulary type, facilitating expressive APIs that can be explicit with their error handling. Introduced in C++17 it saw no extension in C++20 (other than being made constexpr). C++23 brings new monadic operations to optional which enables better chaining of operations.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Imagine we have the following API:<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"cpp\">void subscribe(std::optional&lt;int&gt; id);<\/pre>\n<p><span style=\"font-weight: 400;\">The specifics of subscribe are unimportant, but we do know that we need an optional integer id. Now suppose we read that id as a string from a file, we might end up with the following situation<\/span><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"cpp\">const std::optional&lt;std::string&gt; idString = readIdFromFile();\r\nif (const auto id = idString ; id)\r\n{\r\n    subscribe(std::stoi(*id));\r\n}\r\n<\/pre>\n<p><span style=\"font-weight: 400;\">We\u2019ve got to get the value, check if it\u2019s empty and if not do a cast. The new transform method (which returns the result of an optional from a function if the optional has a value, or an empty optional) helps us collapse all this down<\/span><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"cpp\">subscribe(readIdFromFile().transform([](const auto &amp;s) {\r\n    return std::stoi(s);\r\n}));\r\n<\/pre>\n<p><span style=\"font-weight: 400;\">This is so useful we already have a hand rolled version of this in our code base, which we can now look to replace with a standardised version, further simplifying our code.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Range improvements<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">One of the core improvements in C++20 was the introduction of ranges. C++23 extends its API with new functionality. We already use ranges extensively, but one welcome new addition is zip_transform. This takes a function object and one or more views and produces a view whose ith element is the result of calling the function object on the ith element of the input views. This is useful in the following scenario, say we have a collection of key value stores (e.g. std::vector&lt;std::unordered_map&gt;) and we have a collection of keys we want to remove from the key value stores.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A naive solution would look like this:<\/span><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"cpp\">void process(auto const &amp;toRemove, auto &amp;dataStores)\r\n{\r\n    auto iter1 = toRemove.begin();\r\n    auto iter2 = dataStores.begin();\r\n \r\n    while (iter1 != toRemove.end())\r\n    {\r\n        iter2-&gt;erase(*iter1);\r\n        ++iter1;\r\n        ++iter2;\r\n    }\r\n}\r\n<\/pre>\n<p><span style=\"font-weight: 400;\">This doesn&#8217;t feel like modern C++, we\u2019re manually looping and doing our own iterator bookkeeping. However with the new ranges API:<\/span><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"cpp\">bool process(auto const &amp;toRemove, auto &amp;dataStores)\r\n{\r\n    auto res = std::views::zip_transform(\r\n        [](auto const &amp;a, auto &amp;b) { return b.erase(a); },\r\n        toRemove,\r\n        dataStores);\r\n \r\n    return std::ranges::all_of(res, [](auto const &amp;a) { return a == 1; });\r\n}\r\n<\/pre>\n<p><span style=\"font-weight: 400;\">As an added bonus we can also easily check if the erasure happened!<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Conclusion<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Keeping up to date allows us to fully leverage the language and stay at the bleeding edge of what is possible. We have a dockerised build system which reduces the friction for upgrading compilers. We\u2019re currently building with gcc12 and clang14 and rolling out the clang15 image, so we are ready for the above new features as soon as they make their way into the compilers.<\/span><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Introduction At Maven we are always excited to adopt a new version of C++.
