std::quoted is a C++14 utility that simplifies reading and writing quoted strings.
When used during stream insertion, it will surround the given string with quotes and escape any internal quotes.
When used during stream extraction, the extraction will read the entire quoted string, remove surrounding quotes (if any) and unescape internal quotes.

Correction for previous #dailybiteofcpp.
Unfortunately, I have misinterpreted a corner case behaviour of std::async, and it managed to survive in the example.
The packaged task will not be run automatically when the future is destroyed. You still need to call .wait() or .get() manually.
Thanks to Pavel Pokutnev on LinkedIn for pointing it out.

The C++11 std::async is a simple tool for launching asynchronous tasks to either start a task in parallel or to defer execution on the same thread.
The benefit of std::async is simplicity, as std::async directly returns a std::future; however, we pay for that simplicity with a lack of control.

Tuesday common C++ interview problem: Bus routes.
Given a list of bus routes, where route[i] = {b1,b2,b3} means that bus i stops at stops b1, b2 and b3; determine the smallest number of buses you need to reach the target bus stop starting at the source.
Return -1 if the target is unreachable.

Do you think dependency management in C++ is a pain? Well, I wrote two articles about dependency management with CMake that might change your opinion.
The first part is about using OS-specific package managers and linking installed libraries to CMake, fetching prebuilt releases from git, or using dependencies from submodules. You can read it here: https://medium.com/@nerudaj/dependency-management-in-cmake-part-1-421c6b36417e
The second part is about package managers specific to C++, namely vcpkg and CPM, and how to work with those: https://medium.com/@nerudaj/dependency-management-in-cmake-part-2-478f63794eb5
Hope it helps somebody!
If std::expected should be widely adopted, then #cpp needs an equivalent of Rust's ? operator to quickly return and propagate the error upwards.
Otherwise exceptions have much better ergonomics.

One downside of standard views is their behaviour when marked as const.
As is typical with reference types, views do not respect const. Unfortunately, on top of that, certain combinations of views and ranges require mutability.
With the C++23 std::views::as_const, we can leave the views mutable while enforcing the immutability of the underlying data.

@dustin I had high hopes for it initially, but as the complexity grew…
Right there with you in not enjoying it. I miss Objective-C!
I always felt that Obj-C was what C++ should have been. (C++ is another language that seemed interesting at first, but eventually collapsed under its own weight IMHO.)
TIL that C++ std::map has a "hinted insertion operator" for better performance when you insert a list of sorted items: https://devblogs.microsoft.com/oldnewthing/20230522-00/?p=108226 #cplusplus
I've been on a couple of #Cpp #CplusPlus pod casts with #CppClub recently: https://cppclub.uk/meetings/2023/161/ and https://cppclub.uk/meetings/2023/161/
They are a great way to keep up to date and have both been very interesting.
Question: is a C++ member function defined inside the class definition inlined in the final binary or not?
PS: If you are going to ask about some specific standard, let's pick, say, C++17.
C++ has been around for a long time but has changed significantly since 2011. A new standard, referred to as C++11 was introduced then, marking the beginning of a new era of frequent updates.
If you haven't used C++ since before C++11, you have a lot to catch up on, so where do you start? No worries, Frances Buontempo has you covered: https://bit.ly/3Bhnt7Z

The two arguably most important algorithms in the standard library are the divide and conquer std::lower_bound and std::upper_bound.
These algorithms provide O(logn) boundary lookup on sorted random-access ranges.

So let me get this straight. The Boost C++ library can only be compiled using a bespoke b2 build system that doesn't use a normal make/cmake/whatever workflow, but in order to do that you first have to compile b2 itself using C++.
But worse than that, Boost tries to work out the toolchain itself instead of using best practise conventions like $CC and $CXX, which makes it totally incompatible with environments like conda!

The C++23 added the std::spanstream, effectively a std::stringstream equivalent operating on a borrowed contiguous range.
std::spanstream can be used to directly parse text stored in raw memory, string_views or string literals.
When using std::spanstream for writing, the std::spanstream will write as much output as fits into the output span, which can be inconvenient.

@veronica @lodurel Roughly accurate…
1. #BASIC (C64, Apple IIgs) 1990-?
2. #assembly 1992-1994
3. #HyperCard 1994-1996
4. #CPlusPlus 1997-2001
5. #VisualBasic, #VBA 1999-2001
6. #JavaScript 2003-
7. #VBScript 2003-2004
8. #PHP 2005-
I try random #programming languages here and there but this has really been it. The flavor-of-the-month JavaScript frameworks keep me busy.
In what order did you learn your #programming languages, and what years were you active with them? I'll start:
1. #Ruby 2005-2007 2013-2016
2. #CSharp 2006-2012
3. #AdaLang 2010-2012
4. #CLang 2010
5. #Java 2011
6. #Python 2011-2022
7. #CPlusPlus 2011-2022
8. #RustLang 2016-
I have been able to reduce the overhead to 5-10% which is acceptable (if not ideal).
Things I learned:
* std::views::join is weird
* std::vector{std::move(object)} creates a local copy of object because initializer_lists were created by the devil
Question to #cplusplus folks:
It is nice and easy to reformulate loops as a series of view-transformations, as long as I always transform single-element → single-element; but if individual steps can turn 1→n elements, I need to create a vector of return values and add a join (for each step).
This introduces lots of moves and has a very measurable performance overhead (~30% total program runtime here). Are there better options?
Maybe with coroutines? Can they be chained?
Boosts appreciated ❤️
I've been reading "C++ has become a legacy language" a lot recently; I'm curious what you think.
Has or will C++ become a legacy language in the near future? For this poll, "legacy language" means a language that is mostly driven by inertia and enthusiasts and does not or should not be used for new projects.
Please boost for reach.
@collin refactoring without needing to worry too much, knowing you are safe from synchronization and memory safety issues while still getting highly performant code are awesome. As soon as you stop writing #RustLang like X (no matter if X is #Ruby, #Python or #CPlusPlus), yes, it absolutely sparks joy!
