No, the point was you want don't get a warning and it will silently wrap. You can scroll up if you've forgotten.

And it is false. My default configuration C++ project created in Clion shows it very clearly, and even pesters to use int32/int64 over int/long.

But as usual the default fallback when you're wrong about C++ is "uh yeah but lotta footguns amirite"

As if there aren't enough that we need to start making them up...

And yet RedHat's recommended compiler flags for GCC [0], for example, do not appear to catch the wrapping assignment in the above example code.

Ah yes, of course the goalpost was "you need to customize your settings to catch it" above.

Now that the default in the most beginner friendly of IDEs catches it, the goalpost is "my pet source of customization designed with C++98 in mind doesn't catch this"

Of course, even your pet source of customization caught up: https://developers.redhat.com/blog/2021/04/06/get-started-wi...

If by "caught up", you mean talked about clang-tidy in a separate post, which is definitely not a GCC compiler flag, then sure.

The goalpost, since you're insistent on being explicit about it, was whether a C/C++ compiler "with reasonable flags" will catch the implicit wrap. GCC is a very popular compiler, and to be honest, I'm still not sure how to get it to warn on the above code, if doing so is possible.

Edit: Just read the rest of the thread, it's -Wconversion, which I suppose makes sense. Ignore me, point taken.

If said beginning friendly IDE is used by only a couple percent of the ecosystem, it seems disingenuous to use it as proof this isn't a problem in this context?

[BoorishBears]

Ok so we're going to keep shifting the goalposts, now it's "there aren't enough beginners relative to total usage so beginner friendly IDE isn't enough"...

I mean MSVS uses Clang-tidy too, Clang-tidy integrates style guides provided by Mozilla and Google.

Most C++ Google projects have clang-tidy configs.

Clang-tidy is literally table-stakes for modern C++ tooling.

Github shows 970,000 commits related to setting up clang-tidy

But uh, yeah, let's see where the goalpost skitters to next.

-

The irony is I said above, C++ has enough footguns without sticking your fingers in your ears and ignoring boring, easy to setup, widely well known and well used tooling.

But in the war against C++ no stone must be left unturned.

C++ is a tiny fraction of all the code I've written in my life but it irks me to no end that people can't deal with the idea that language safety can improve, that tooling can be considered part of that safety. Or rather they can... unless they're talking about C/C++

[lazide]

I’m definitely not moving any goalposts I know of!

I thought the point I had been making, as had others, is that by default this is an easy footgun.

There are all sorts of things that can be added on to all languages to help - if you know it’s a problem worth solving, etc. which is inevitably after you’ve footgunned yourself with it bad enough you felt the need to research how to prevent it.

Other languages just do the safer thing (or most compilers By default warn at least about common footguns) more - which is the whole point of this thread?

[BoorishBears]

There was one point, C++ won't warn you by default .

But tooling that is incredibly common, that beginners will run into even if they take the path of least resistance, and experts will use because it enforces standards at the very least, covers it.

Like Js without linters is a minefield, but everyone accepts you should lint your Js. Why does that change when C++ is involved?
