As it stands now, every concept has exactly and only one definition. As such, the relationships between concepts are known and fixed. Consider the following:

The "(optional)" marker in cppreference.com documentation

Asked 2022-Jan-04 at 14:27

Last week, I had a discussion with a colleague in understanding the documentation of C++ features on cppreference.com. We had a look at the documentation of the parameter packs, in particular the meaning of the (optional) marker:

(Another example can be found here.)

I thought it means that this part of the syntax is optional. Meaning I can omit this part in the syntax, but it is always required to be supported by the compiler to comply with the C++ standard. But he stated that it means that it is optional in the standard and that a compiler does not need to support this feature to comply to the standard. Which is it? Both of these explanations make sense to me.

I couldn't find any kind of explanation on the cppreference web site. I also tried to google it but always landed at std::optional...

QUESTION

Understanding the point of supply blocks (on-demand supplies)

Asked 2021-Oct-05 at 23:02

I'm having trouble getting my head around the purpose of supply {…} blocks/the on-demand supplies that they create.

Live supplies (that is, the types that come from a Supplier and get new values whenever that Supplier emits a value) make sense to me – they're a version of asynchronous streams that I can use to broadcast a message from one or more senders to one or more receivers. It's easy to see use cases for responding to a live stream of messages: I might want to take an action every time I get a UI event from a GUI interface, or every time a chat application broadcasts that it has received a new message.

But on-demand supplies don't make a similar amount of sense. The docs say that

An on-demand broadcast is like Netflix: everyone who starts streaming a movie (taps a supply), always starts it from the beginning (gets all the values), regardless of how many people are watching it right now.

Ok, fair enough. But why/when would I want those semantics?

The examples also leave me scratching my head a bit. The Concurancy page currently provides three examples of a supply block, but two of them just emit the values from a for loop. The third is a bit more detailed:

...

ANSWER

Answered 2021-Oct-05 at 23:02

Given you mentioned Supply.merge, let's start with that. Imagine it wasn't in the Raku standard library, and we had to implement it. What would we have to take care of in order to reach a correct implementation? At least:

Produce a Supply result that, when tapped, will...
Tap (that is, subscribe to) all of the input supplies.
When one of the input supplies emits a value, emit it to our tapper...
...but make sure we follow the serial supply rule, which is that we only emit one message at a time; it's possible that two of our input supplies will emit values at the same time from different threads, so this isn't an automatic property.
When all of our supplies have sent their done event, send the done event also.
If any of the input supplies we tapped sends a quit event, relay it, and also close the taps of all of the other input supplies.
Make very sure we don't have any odd races that will lead to breaking the supply grammar emit* [done|quit].
When a tap on the resulting Supply we produce is closed, be sure to close the tap on all (still active) input supplies we tapped.

Good luck!

Why does VSCode not recognize the JavaScript spread operator and autocompletes instead?

Asked 2021-Sep-10 at 11:39

I have been struggling with a really annoying behaviour of Visual Studio Code recently.

Whenever I try to use the JavaScript spread syntax VSCode automatically autocompletes the next piece of code (wrongly). Note I am NOT hitting TAB. Here's a demonstration of what I'm talking about:

Can comparison operator be defaulted outside of class definition in C++20?

Asked 2021-Sep-05 at 13:32

Starting from C++20, the compiler can automatically generate comparison operators for user classes by means of operator ==() = default syntax. But must this operator be defaulted only inside the class definition or can it be after the class definition as well?

ANSWER

Answered 2021-Jul-28 at 06:48

One possible avenue to explorer would be to add the action commit-status-updater in order to set yourself the status check you want.

A simple Github Action that allows us to update the status of a commit.

GitHub does not update the status of a commit when running workflow and therefore tools that rely on the context/status of a given commit are not compatible with it.

Currently the action supports pull_request and push events:

When the event is pull_request, the action will set the status to the last commit in the pull request at the moment the workflow was triggered.

When the event is push, the action will set the status to the last commit pushed at the moment the workflow was triggered.
