I deliberately removed the "static" methods, so that above would not be allowed. Why I found that to be a good idea is a longer discussion. The main motivation why it is nice to have it this way is that it's straightforward t

No, that's probably not a good description. I'm not saying you will appreciate the language, but it is basically C. - "Failables" (which is somewhat like Result) offers an alternative to error handling which mostly mirro

Some things are hard to get rid of due to LLVM, but I'm doing my best to reduce them.

- Format strings, are you thinking about string interpolation or? - A module isn't a file in C3 but that's a deep subject to get into. - Automatic C header file import is something Zig is also touting as a feature. This was someth

`ptr = array` vs `ptr = &array` (no [0] needed) is also part of being able to capture array sizes during compile time for macros, and also being able to copy arrays by value in an easy way. I don't think there would have been a way

For the docs, have a look here: http://www.c3-lang.org With a primer for C programmers: http://www.c3-lang.org/primer/ It should compile fine on MacOS and Linux. There is CI for Windows but the readme is mi

Agreed, haven’t heard of that until I read about it (I’m 48, living and working in Sweden)

Could another approach be taken, where local variables are considered implicitly “register”? In that case this simple example has no problem whatsoever. It does arise unnecessarily if the address of a local is taken but does not escape, but

There are many ways to approach macros. Zig’s approach with compile time evaluation handles many of them. Esp since types can be created on the fly. Another approach, which is strongly inspired by the ASTEC project for C, is what I use for

It should be noted that Zig’s int promotion rules are currently broken though.

On the other hand, leave out “pub” and Zig won’t compile it…

So, consider passing a struct A stored in the global variable “foo” to the function “bar” in the parameter “baz”. This function makes a modification to the global “foo”. The compiler cannot know this happens and so the value of “baz” is now

UML died because while people were buying UML to live the dream that programming could now be reduced to charting classes, real programming doesn’t work like that. All it added was some meaningless documentation that looked impressive but g

No, I'm aware of it. GCC also has a similar feature as a C extension. I picked those languages because they very clearly use the same keyword.

If I may venture a guess, it is because this way there is no limit in regard to jumps within or out of a function. Since Go retains `goto`, function based is easier to implement. In addition, non-local jumps, such ones constructed by setjmp

I’ll buy it so that my kids can grow up learning basic in the old school way. The Spectrum basic was one of the best back in the day. I’ve been teaching them using a C64 emulator but that Basic is pretty lacking.

Having a full size C64 that’s based on emulation I would respectfully like to disagree. First of all the emulations all end up with minor glitches. Second, a machine like the Spectrum Next outclasses most emulator based machines by running

As alternative, I introduced “failables” into my programming language C3. It has the benefits of Go error handling but none of the downsides. I wrote two blog posts as I developed the idea: https://dev.to/lerno/a-new-er

Yeah you should totally do like Sweden where dead remains at a constant high level and where reduction to a low number of cases per day is very very far away. This “almost lockdown” strategy is almost equally hurtful for the economy but wil

I wonder how they propose to solve exceptions, destructors, constructors and overloading while being more compatible with C than D. Apparently a beta was promised for "early 2019" according this: https://github.com&#x2F

It’s interesting how “evolutionary approach” is used. Compare with C2: http://www.c2lang.org/ I think that in the case of C2 it’s still a language that will rely on the same paradigms as C, whereas C-for-all is more of a “k

My take on why OO - as usually taught and practiced - is problematic: https://link.medium.com/GEgk2vjLpZ In short: it requires a lot of up front design and abstract thinking, plus the idea to architecture a program around s
