templates

Thanks to C++20, lambdas become more powerful. From the various lambda improvements, template parameters for lambdas are my favorite ones.

Admittedly, I present in this post a few small improvements to templates and to C++20 in general. Although these improvements may seem not so impressive to you, they make C++20 more consistent and, therefore, less error-prone when you program generic.

Variadic templates are a C++ feature that looks quite magic the first time you see them. Thanks to C++ Insights, most of the magic disappears. 

Today's post from Andreas is about template instantiation. C++ Insights helps you a lot to get a deeper insight into this automatic process.

I assume you saw the additional keywords typename or template used before a name in a template. Me too. Honestly, I was quite surprised. Today's post is about dependent names and various template parameters.

I often teach the basics to templates. Templates are special. Therefore, I encounter many misconceptions which cause surprises. Here are a few of them.

Today, I finish the C++ core guidelines rules to templates with a big surprise for many C++ developers. I write about the specialisation of function templates.

Today, I write about the few remaining rules to templates. Because a collective name is missing, they put the heterogenous rules to templates in the section other. The rules are about best practices but also about surprises. 

The type-traits library supports type checks, type comparisons, and type modifications at compile time. Right! Today, I write about type modifications at compile time.

My journey through programming at compile time began in the last posts with template metaprogramming. Today, I jump from C++98 to C++11. This is a jump to the type-traits library which is template metaprogramming in a standardised way.
