Mnot what keenan meant
Aah
Aoh wait
literally something that transpiles c/c++ into c#?

Dyeah
Athere is something out there that exists
AI think it only works with C though
Ait's used in StbImageSharp
Mnot all C is transpilable to C#
TClangSharp handles basically everything it can. The stuff it can’t handle is stuff like templates, because there is no equivalent
TIt could try to do generics and type checks in some cases, but it doesn’t translate cleanly without interface constraints
And of course you can’t implement such interfaces on existing types you don’t own
And of course you can’t implement such interfaces on existing types you don’t own
Dcould you not pre "expand" the macros then translate that to C#?
Lthat wont work for the macros themselves
Lsure you can preprocess it
Lbut after you preprocess it then you can no longer try to turn those macros into function calls
La good amount of libs provide macros for end users to use
TRight. ClangSharp even handles many types of macros
But there’s plenty where it only works expanded directly inline

Doh, so you were talking about macros that I as a consumer of an api would use
TYou can’t really make std::vector port to C# for example
Mdoes stack memory in c# behave like c
TYou can get something close manually, but it doesn’t work when done automatically
Dcouldn't you just replace things like vector with list<T>?
Myeah, but you can't generically do that for any C++ class
TNot always, you can do things like vector<t>* in c++ for example
TAnd otherwise it’s by value
TIterators as well are done via template expansion
TThe issue isn’t whether or not you can find an equivalent, it’s about whether you can automatically do that such that it can be done by a tool
Dso rather than doing a convert from syntax A to B, you would need to do a whole bunch of detecting code patterns and do the best you can to replicate it in C#
TRight. And for something like a library, you can’t determine the full set to find a valid type to port to
TThat is, you can’t do “whole program analysis”
TFor something like mimalloc, I can get like 75% automatically done and then need to do the other 25% by hand
But doing the whole thing by hand is significantly better perf, maintainability, and readability wise

TBecause as a human I can rationalize things that are lost in the C AST (macro expansions) and can opt for cleaner or more efficient alternatives using C# syntax that isn’t necessarily 1-1 but achieves the desired outcome and intent of the original source

The Use functions rely on reflection doing the right things, which isn't necessarily correct on AOT.

Pwill look tomorrow, annoy me in about 12 hours
Pokay i'm going to have a shower now
Mcya!
Pwhen i come back that PR better be green or someone else is doing the release haha
P(i've just checked and you need Nitro to post the release notes in #announcements, and I am NOT writing a blog again)
Mif anyone has an idea for a better implementation for this, let me know
i wonder if the JIT can devirtualize something like this?

Mperks, GO SHOWER
Kid also include numerics vector3
MPLEASE
Koh wait numerics vector3 doesnt implement inumberbase does it
Mye
Mexactly
Poh i thought you were going to make a comment about how you can't make it green to which i was going to point you to the most approved PR in GitHub history https://github.com/dotnet/sdk/pull/22262
Mi'm not a maintainer
Pbut yes that'll be implied
