While designing an ADL based API, I got bitten by ADL and accidentally called a function from the std namespace. I think I'll switch to deducing this instead #cpp #cplusplus #adl

I have a question for people with better theoretical background on #ObjectOriented #programming and especially for #CPlusPlus developers.

#askFedi #fediHelp Is the following pattern known and does it have a name?

I have a number of classes (call them C1, C2, etc) that all derive from the same class B. I have a superclass (template, actually) D that derives from C1, C2 etc. To have a single B, the standard solution is to go with virtual inheritance to close the diamond (so far, so good).

I think there would be still space for systems programming language with a constraint from day zero that it would 1:1 compatible with plain C”s binary layout and memory model:

1. Roughly just .text, .bss, .rodata and ,data.
2. No symbol mangling at all.

All the memory safety etc. fancy features would be then designed within exactly those constraints.

#Rust is essentially a derivative of C++ when compiled to binary, which does not really make it a strong competitor for plain #C. It can substitute C in many cases for sure, just like C++ did, but there’s always need for minimal systems programming language, which also looks elegant in binary, not just in source code.

A compiled C program can be quite easily understood with a binary with no debug symbols at all if you understand the CPU architecture well enough. That is, and will be a strong asset for C.

All you nutcases still using #Perl, what's actually wrong with it?

Dear Fediverse,

in case you care, I'd love if you'd vote for this issue of mine:

Serious constant evaluation and C++ modules seem to live on different planets.

Thanks, much appreciated! 🩷

If you're doing a lot of work in C/C++/Rust consider using sccache to cache compilations. It's easy to set up and will save you a lot of time and a huge amount of power.

https://github.com/mozilla/sccache

As an example this is just a couple of hours of work on Firefox, it saved me from re-running the compiler almost 90% of the time.
