C++ as Assembly 2.0 - Hello Nim - Viktor Kirilov - code::dive 2019

*Abstract*

In C++ it takes more than 5000 lines of code to properly implement optional - a value and a bool (hopefully without bugs and design flaws - fingers crossed! and let's not mention build times…).

Nim is a statically typed systems and applications programming language which offers some of the most powerful metaprogramming capabilities. It is the next iteration of imperative language design and aims to dethrone C/C++ for high-performance coding - among its rivals are Rust and D. Nim is also perfectly suited for software typically written in C#, Java, JavaScript, etc. - basically all types of software. Nim can bridge the gap between business logic and high performance, sprinkling improved developer productivity on top. Nim is compiled to C/C++ (and JavaScript among others) and thus interoperability is straightforward and without any performance penalties - lots of existing C/C++ software can be reused and built upon.

The talk outline is as follows:
- the landscape of (compiled & high performance) programming languages and their use in the industry
- thoughts on the evolution of C++ and where it fits
- introduction to Nim - features and capabilities
- metaprogramming and introspection in Nim (HTML DSL example)
- the whole-program compilation model of Nim - how the compiler actually works and what the generated C++ code looks like
- a thorough comparison with C++ (language features and workflow)
- interfacing with C++
- the future of the language and ways to go forward

It's time to treat C++ as assembly and the C++ ecosystem as just another platform which a language such as Nim can target. Typescript is a bright example of a better tool for software development on top of a stable system.

*About the Speaker - Viktor Kirilov*

With 7 years of professional experience with C++ in the games and VFX industries, Viktor currently spends his time writing open source software (since 01.01.2016) - and occasionally doing some contract work. His latest work has been the implementation of hot code-reloading at runtime for the Nim programming language. He is also the author of doctest - "The fastest feature-rich C++11 single-header testing framework". His interests are the making of games and game engines, high-performance code, data-oriented design, cryptocurrencies, optimizing workflows and incorporating good practices in the software development process such as testing and the use of modern tools like static analysis or instrumentation. Viktor is from Sofia, Bulgaria and his profession is his hobby.

Keep in mind that for the first 18 minutes or so the HDMI capture didn't work so they later sync-ed the .pdf slides I sent them which don't have the animations of bullet points and code highlights.

Excellent talk, I'm definitely sold on Nim.

Very nice presentation, thank you Viktor.

Does this have anything to do with either C++ or assembly?

"...aims to dethrone C/C++..." "...compiles to C/C++." Sigh.
