I'm learning C++ and as starting project I'd like to build a simple TUI program, something like neofetch. Do you have any suggestions of a good library I can use to manage the TUI? After some research I sumbled upon ncurses, which seems quite old tho, and notcurses, which to me looks quite cool. Which of the two would you recommend? Are there any better libraries? I thought that maybe, being quite widely used, ncurses is more worth learning, but I'm open to different opinions.

This one was quite a struggle, thought I'd share for the C++ programmers here.

I have a use case where for many function templates I have to instantiate them for a bunch of different parameter types, e.g. unary, binary and ternary functions where each argument can be one of 9 different types, giving 9, 9^2 = 81 or 9^3 = 729 instantiations of each function. Clearly I don't want to write those out as explicit template instantiations, and using macros is error prone too.

I've found this approach with std::variant and std::visit to be useful. Would appreciate any insight on edge cases where this may not work, or other suggested approaches.

I use Helix Editor and by default it uses clangd as LSP server.

But when I use "newer" C++20 features I get warning messages in the editor that they are only available in "later" C++ versions or I get straight up error messages.

So how do I tell clangd that I am writing C++20 code? I am guessing passing an argument (-std=c++20) or creating a "project properties" file...

This is the Helix Editor configuration file, languages.toml:

[[language]]
name = "cpp"
language-server = { command = "clangd", args = [] }
auto-format = true

Please let me know the right way to do it.

Recently I end up using structs everywhere as functions parameters to basically get named function parameters and better default arguments. Are there any downsides to this? So far the only annoying thing is to have to define those structs.

struct FunParams{
    int i = 5;
    float f = 3.14f;
    std::string s = "hello";
};

void Fun(const FunParams& params){}

int main(){
    Fun({.s = "hi there"});
}

I follow (probably too many) a bunch of news source regarding programming, and a few weeks ago I started putting everything in a RSS reader, so that I can a single feed/app to go to (instead of remembering every day/week to check x, y, a websites), so I made a script for totw/cpp to help them generate an RSS feed when a new tip is posted.

It might need a few more tweaks to be perfect (markdown to html to XML CDATA sometimes messes up), but it works well and I can finally enjoy reading tips easily anytime, and so can you!

im new in c++ and i am creating a version of cat for practicing what i have learned so far. What im doing for managing the command line arguments is converting them to library strings and then using them, but now i have the doubt if it is the correct / most optimal way to do it

Do you want to encrypt something and include it into your application? Don't want to use pre-build step? Encrypt it at compile-time! Decrypt it at run-time, assuming end-user knows the key or password. Plain-text is not stored inside your binary file. https://github.com/MarekKnapek/mk_clib#constexpr-aes-256-encryption-and-run-time-decryption
