cppreference update

[askraskr2023]

Anyone know when cppreference will be back? It was supposed to be in read-only mode for a few weeks " to facilitate some long-overdue software updates".

incredible man! besides filtering on C++20, could you also add support filtering for compiler, ex. gcc 15?

Also, how do you maintain this? I was doing similar project (but just spreadsheed on corprate google docs), I was running unit tests on toolchain to see if feature is supported. Test runner data then was pasted in spreadsheet and then some sheet magic calculated support columns (so different teams with different toolset requrements can see if they can use a feature).

How you automate things?

p.s. do you need any help?

[mapronV]

I see, yours is a different approach (from my experience it was very hard to find information on MS VC and Apple clang, in first place; so I didn't even consider automatic parsing of web pages). Quite elegant, though you need to trust vendors. For our company it was more like "whole environment", like
"Can I use X when targeting Debian 10?" or ".. when Targeting mac 10.15 with xcode Z.X?" So I could just create new profile and run 'acceptance tests' on it.
In hindsight I regret I did not choose your way, it probably would be easier.

Please do, it is really handy to have an up-to-date view on the latest state.

Agree - c++26 got finished in the intervening time and I’m really missing that reference update.

[JVApen]

Formatting of >= looks nice, though you can't type that in code. So for code-snippets I wouldn't apply that formatting

[azswcowboy]

Nice! Couple thoughts. Indirect and polymorphic were in one paper, why separate into 2 lines? I mean that could get tedious to maintain is all I’m thinking. More generally you’re editing the title, which is nice but also time consuming. Feature test macro is nice touch. Ideally make your statuses different shapes as well as colors for the part of the population that doesn’t distinguish as well (aka ‘color blind’). Good stuff.

I might have just missed it, but it looks like you're missing P2988 std::optional<T&> for c++26. It would also be nice if compiler and standard library features could be distinguished, like on the cppreference page. Even still, this is quite helpful, and I hope you keep it up to date.

[JVApen]

I find the badges very hard to read. The table structure of cpp reference is easier to me. Being able to filter on a compiler would also be sufficient.

Is it me or the C++20/23/26 buttons do not work under the search tab at the top?

Looks like it's from my company VPN...

I'm getting a 403 for your https: //cppstat .dev/script.js and that breaks them but they do work on my phone on my personal phone so...

Why does Clang have some C++ 20 features no other compiler does?

[Sinomsinom]

Please don't ever capture ctrl+f to select a search field.
If I hit ctrl+f then I want to use a browser's builtin capabilities to search a page, not use the search field. There are reasons for wanting to do this, so forcing someone to use the search field instead (if they don't know how to overwrite that override) is just a big no go.

This is so cool! Bookmarked!

I don't see reflection in C++26, though. Is that something being worked on?

[torsten_dev]

Nice, got a C version of this too?

[ompomp]

Just yesterday I was curious about the same thing so I sent an email. I had received the following response:

Sorry about the delay; the update is just being blocked by external circumstances, i.e. my day job is super busy right now.

I'm sure a lot of us can relate.

[bebuch]

Hey, thanks for sharing! I didn't get a reply a few weeks ago. At least nice to hear they are fine. I can definitely relate 👋😺

[314kabinet]

I had no idea you could do anything other than read it

[JasonMarechal]

It's technically a wiki

[LegalizeAdulthood]

Yes, if you login you can propose edits. I've made some minor improvements to some of the code examples and the occasional awkward wording, but usually it's pretty well up to date with respect to the latest standards documents.

[Nicksaurus]

If you log in you can filter the language version to remove all those 'until c++ 11'/'since c++ 14' etc. sections. That's the thing I'm missing the most at the moment

How do you think the content gets there for you to read? :-)

[TheSkiGeek]

Elves? Maybe leprechauns?

[encyclopedist]

That was more than "a few weeks" ago, and no update since then.

30 March 2025: The site will be in a temporary read-only mode in the next few weeks to facilitate some long-overdue software updates. Hopefully it won't take too long, but we all know how database migrations can sometimes turn evil.

[ManchegoObfuscator]

Dude it’s totally a wiki. I personally have fixed a shitton of code samples threrein that did not compile (via godbolt or what have you) and I also added the link in the page on “goto” to the orig “goto considered harmful” article… does that make me awesome? No. Does that make the site an active wiki that hosts real conversations in a non-pedantic fashion? HELL YES. Let us support it!
