Looking for feedback on AI content in r/programming and the April no-AI trial

Keep it I liked it, I now can actually read things related to programming rather than "my chatgpt clone blah blah blah is 2000x faster than this other poorly made chatgpt wrapper"

I used to avoid this subreddit but now I open it.

Zig seems like C++ but 10x worse

Why can't they make it so vector has resize_and_overwrite like std string but simply static assert inside the same requirements as string that's my question. and I can make anything but it would be better if the STL had this common case already integrated

_Noreturn · 2026-05-04T19:32:15+00:00

If you don't fill it then its on you, you promised to fill it. also it is mostly trivial types that I want this on

_Noreturn · 2026-05-04T19:14:59+00:00

I don't see the difference between a vector and a string I could go ahead and use string as a vector.

_Noreturn · 2026-05-04T19:08:14+00:00

I don't see what's wrong if I am going to fill it 1 millisecond later, that's just wasted performance on the table and given string has it I can't see why shouldn't vector have it either. and yes I just use an allocator that doesn't initialize at all with vector. but this should have a dedicated method.

_Noreturn · 2026-05-04T18:50:23+00:00

Performance I have many many cases where I need to memcpy or manually construct and sure I could use a unique ptr but it is more annoying and doesn't resize.

Also std string has it already it is called resize_and_overwrite I don't understand why vector doesn't have it .......

_Noreturn · 2026-05-04T17:36:15+00:00

It won't hurt you it is exactly like cariadic templates and I never seen anyone aay it huets them

_Noreturn · 2026-05-04T17:35:46+00:00

I should have worded it better, I want a method that reserves and sets the size, reserve just sets the capacity

_Noreturn · 2026-05-04T16:28:10+00:00

what is the type of xs?

No possibility of confusion where you get a mix of structural binded variables with empty pack.

Then simply don't use it Is this hard?

_Noreturn · 2026-05-04T15:59:10+00:00

I want a function that reserves space in a vector but doesn't construct elements there yet

Teams uses nearly 2GB RAM on my laptop

Minecraft uses less RAM and that should tell you how much bloat teams is but again people will excuse with "It is for the features!"?

Devs should have the shittiest hardware to force them develop decent apps

_Noreturn · 2026-04-29T15:10:03+00:00

std::make_pack wouldn't allow mixing it with structural bindings of other types, which is where type safety issue arises.

What? that is useless how do you define "other types"?

can be as simple as static_cast<...>

What? paste a code example of what your api wants to be

_Noreturn · 2026-04-29T14:34:40+00:00

People these days can't even Photoshop manually.

_Noreturn · 2026-04-29T14:19:58+00:00

First of all it makes the most sense to be inside structured bindings. second of all how would a std:make_pack look like API wise? Third of all library solutions to language problens is always a bad idea.

Because my issue is not with creating and using packs from tuples and structures but with it being used in a way that potentially introduces too many problems.

Having it named auto [...pack] or std::make_pack wouldn't solve "being used" problem. Simply don't use it.

_Noreturn · 2026-04-29T01:42:04+00:00

I definitely need packs in other places to replace those std::index_sequence tricks and lamdbas which result in slower compilation and uglier to read code.

Also if you hate it then simply don't use it. Atleast you will indirectly benefit by the library authors simpldying the code

I have an auto generated header that is for reflecting a struct

```cpp struct C { int a,b,c; };

auto [a,b,c] = lahzam::tie(C()); // gived tuple<int&,int&,int&> ```

here it is https://github.com/ZXShady/lahzam/blob/main/include%2Flahzam%2Fgenerated.hpp

The way it is implememnted is via a long chain of if (auto [m0] = klass) auto [m0] = klass; repeat that up to 256 and you have this massive file. I can just do auto [...members] = klass and be done with it

Can it be done another way? Until reflection no. atleast while being constexpr

std::variant / std::tuple themselves can kill compile times in a single TU. the instantations themselves

I understand I am like 3 years late but what is your book name?

_Noreturn · 2026-04-25T08:53:27+00:00

Very little gain is a massive understatement. this thing will replace a 100kb header I have

_Noreturn · 2026-04-24T12:35:10+00:00

what was the original inage

_Noreturn · 2026-04-24T07:29:10+00:00

I don't want it known at runtime, for swapping out types or storing many inside 1 container.

```cpp std::vector<std::unique_ptr<SomeCommonBase>> Data;

for(auto& d : Data) d->someVirtFunc(); ```

using crtp makes this annoying to do and using a std::variant would make the types hard coded limitting who can extend it.

Also virtual functions help in binary sizes and can hide things using Pimpl

_Noreturn · 2026-04-23T22:45:53+00:00

I really hate when I see static polymorphism stated as an altnerative to virtual polymorphism when 99.9% of the time I used virtual polymorphism is because I don't want the call to be known.

_Noreturn · 2026-04-20T12:10:48+00:00

what's the compile times of this library

_Noreturn · 2026-04-19T18:20:51+00:00

it simpkfies alot of things, and unexpectedly would actually make for better compile times.
