Are #defines and -D defines treated differently in C++?
<awang>
I'm trying to deal with this VS 2017 15.8 extended aligned storage thing
<awang>
And I trip the static_assert if I use #define in the .cpp before including any headers
<awang>
But don't trip it if I define the macro on the command line
<egg|work|egg>
O_o ?
<egg|work|egg>
what aligned storage thing
<awang>
VS used to be non-conforming when instantiating std::aligned_storage with an alignment > alignof(max_align_t)
<awang>
It just used min(alignment, alignof(max_align_t)
<awang>
The new VS does the right thing, but that breaks binary compatibility, so there's a static_assert to force you to pick one behavior or the other
<awang>
The static_assert is hidden behind some #ifdefs, but I can't seem to skip the static_asserts

UmbralRaptop: how pedantic do you want your answer
<UmbralRaptop>
moderately pedantic
<egg>
UmbralRaptop: basically the "Greek and Coptic" block is \mathrm
<egg>
but that depends on your typesetting style; in french greek is always roman
<egg>
at the end of the day if you're not doing fancy typesetting and you're not relying on italicizing for semantics the greek and coptic block is fine, otherwise treat it as mathrm (and same for basic latin)
<egg>
UmbralRaptop: i.e. if it's a context where ax + b is OK, cos (ωt + φ) is fine too; if it's a context where you would write 𝑎𝑥 + 𝑏, write cos (𝜔𝑡 + 𝜑), unless you are doing french typesetting, in which case write cos (ω𝑡 + φ)

Since I don't use italics in IRC, diapsid, or synapsid website, those should be okay. Sounds like I need additional care in LaTeX.

eyes the AAS stylesheet.
<egg>
UmbralRaptop: so XeLaTeX with the unicode-math package will emit those for you
<egg>
UmbralRaptop: basically when you are at the level of typesetting finery that requires the mathematical alphanumeric symbols, you very quickly slip the bounds of what can be done in plain text and use Unicode + additional markup to achieve the desired rendering
<egg>
bofh: which is why it's not really a problem that mathrm is unified with basic latin/greek and coptic
<egg>
bofh: these alphabets are for stuff like mathml
<egg>
(actually a lot of this was explicitly made for mathml)
awang has quit [Ping timeout: 198 seconds]
<bofh>
egg: wait, how does this being for mathml imply that it's not a problem that mathrm is unified with basic latin/greek?
<egg>
bofh: because the higher markup means that the browser knows that it should select a math font for this stuff (which is within mathml markup), which better be a serif font
<bofh>
egg: but if it were not unified you could do the same *without* higher markup just as well
<egg>
but you can't use \frac etc., you can't actually render equations in plain text
<bofh>
Yes, but you can get a large amount of the way often using just unicode chars and combining chars. You can't do *layout*, but often that's unnecessary.
<egg>
hell, you can't even use ^ and _, and the superscripts aren't designed for that anyway
<egg>
bofh: you *can* do a large amount (far more readable than just TeX source) in plain text, but for that you don't really need the mathematical alphanumeric symbols
<egg>
in cos (ω^(k/2) t + φ), the readability issue isn't the italicization of t and k
<egg>
when you get to the level of typesetting refinement where you care about mathrm mathbf mathit and whatnot, you want layout too
<egg>
bofh: you even have a plethora of papers with layout and no mathbf mathrm mathit distinction, in the typewriter era
<egg>
~handwritten greek and diacritics and typewriter latin at weird offsets~
<egg>
bofh: fraktur is a thing that may actually improve readability in a plain text context, since it has a very standard distinctive meaning (but there's no unification issue there, they didn't unify basic latin with fraktur :-p)
<egg>
also a very distinctive look, which means that even in a poorly typeset or a handwritten environment you will preserve the fraktur-"normal stuff" distinction
