Back to Basics: Templates in C++ - Nicolai Josuttis - CppCon 2022

It feels, to me, i have to know all of c++. Idk why. Whenever he waives his hands on some somewhat deprecated or irrelavant topics or on some dark corners, i t feels unsatisfactory...

Super Sir, impressed :)

thank you. even better the second time around! : )

Great talk

That's a pure pleasure to listen to the prelection like this. Thank you!

Keep C++ away from stupid politics

Great talk man!

We need an "if compiles{" expression that takes the first branch if the code in that branch compiles 😅

Good stuff...

Hands down the best templates course I've ever had. Thanks!!

Very useful

C with better structure, which is c++.

This is why a TypeEval function is screaming to be created. I am 100% certain the std::people can create a better one than I can. Typeid() doesn't actually consider a tuple of string/int/string the same type as a tuple of variant/variant/map as the same types so there is no secure way to funnel them into whatever place or process they need to be. A bool function is totally fine as long as it is general (i.e. one container type instance should match with another, and with its type-name, regardless of their particular flavor of chaos inside). Knowing everything at compile time is neither realistic nor creatively workable. "Strongly typed" needs to not just be a begrudging neurosis or a religious mantra but also lead to supplying the proper tools for the coder to secure this strength on his or her end.

CppCon please keep politic out.

Do you job. Do not go politic.

Wow, this is trippy. Didn't know this was a thing:

if constexpr (requires {coll.push_back(val);})

love his tshirt. where can I get one?

I call function templates for 145 000 different types, so I end up with 145 000 functions generated. Wow, really nice feature.

Wow the master himself. His book on templates is excellent. Thanks for this video.

Excellent talk, thank you.

Great talk. I believe that understanding templates reveals most of the C++ programming language.

Looks pretty exciting!

Very good! Thank you for the talk!

This is exactly what I was looking for! Great talk!

Templates are pretty awesome now, as is this talk ;)

A truly insightful talk!

Very cool talk. Always good to recapitulate the basics - there are to many things we use without understanding the underlying tech and history.
BTW: Where can I get this awesome T-Shirt?

Josuttis, thank you.

Well done! Engaging throughout.

Nico is a great speaker, I've been looking forward to this one!

nice talk.
i had one query on slide no.31, why recursive call to "if" statement when you know number of var args. why not "range for".
