Odin isn’t as well known as Zig, true. But what you seemed to argue was that this was a deliberate choice by the Odin community: to look for hype on Hacker News rather than doing the leg work of getting a Wikipedia article about the languag

What works for Rust works for Rust. My intent is to make code feel similar to C namespacing. What works and what doesn’t is fairly contextual, depending other language semantics as well.

Destructors and Ownership implies RAII and all the design and architecture that are assumed with such things. This is far from C semantics, and so out of scope for C3. Any RAII language will be considered a C++ competitor, not a C alternati

I asked and got Bas's[1] permission to use C3 as a name when I first started out. [1] Bas van den Berg, the author of C2.

It is possible to use a single-header library as part of C3 libraries or your project. However, it must be noted that this will inhibit the ability to cross compile, as the compilation of the header is outsourced to the natively installed C

C3 allows arbitrary extensions of any types, so things like `vec1.dot(vec2)` is actually implemented as a generic method macro over all vector types added by the math module. Given Zig's preference for closed modules, I don't expe

Back in the day when C's closest competitor was Pascal, C wasn't particularly hard to use. Pascal was easier for manipulating strings and C better at doing low level data manipulation. But at the time there was little need for hig

No, they are the same.

Ah, that is indeed true. However, the plan is to have the language fixed at 1.0, only updating stdlib and tooling after that.

If you want to have your own Base32 where giving a padding = 0xFF instead returns an error, it's commonplace to have a wrapper that will explicitly do the check and return an error if it fails, and otherwise call the function: ma

I tried Zig in 2017-2018 span (and as part of research I've read quite a bit of Zig over the years). To me the language had some details not previously tried out: special operators for wrapping ops, error value based error returns and

There is an overlap between module and class namespacing through static members and functions. Zig sees this and says "let's only have the latter" (on structs), which means among other things that in Zig a file is a structure

I don't like to say "never", because other things make change that invalidates previous conclusions. For example, let's say that for some reason macros were removed (this is very unlikely to happen, but as a thought ex

It's a good language, you should try it out as well.

If I would have liked, I could have done something like `import std::io::file as file;` but I noticed that we keep getting this issue that we’re renaming things all of the time, and usually in the same way. This is why path shortening is th

Blake2 and other hashes are most welcome. As for HashMap you are completely correct: there are many different types of maps that are needed. Concurrent maps, insertion ordered maps etc. And even variations of the small things: are keys copi

This is not that novel. It is inspired by the similar feature in the Odin language.

Also, `fn` is used to make type inference for lambdas syntactically simple. But I would lie if I said I haven’t been considering removing `fn` many times. But there are good reasons for keeping it, despite the break with C.

Isn’t it a somewhat unfair characterization that ”C3 promotes itself more” and ”is pushed on HN and other social media” and that because of this C2 for some reason experiences harm? C2 is over 11 years now. C3’s recent breakthrough this las

The difference here is that a preprocessor runs before parsing and semantic analysis. In C3 compile time if runs in the analysis step, so after parsing. So the macros and compile time execution occurs after parsing in C3, but in C everythin

But you have to. Ambiguities hint at lack of redundancies that also affects code reading. When you quickly scan something like `file.open` vs `file::open` the former is also more unclear to a reader without more context.
