Parse command line arguments by defining a struct. Contribute to p-ranav/structopt development by creating an account on GitHub.

Structopt for C++ is a library that simplifies parsing command line arguments by allowing developers to define a struct that represents their program's expected inputs. Instead of manually writing argument parsing… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

   How to program in Rust as if it was old school C++ with pointers▲24

   Basically wrap your data struct in Option>> Better yet, use your custom type that provides few helper functions that make using it as nice as old C++ pointers. Obviously there's no pointer arithmetic, but it works great for dynamically allocated structures like trees or linked lists. Please comment how it's a horrible idea that will bring doom to me and my family. fn main() { struct Data { pub number: i32 } // struct Data { int number; }; let mut p:Pointer = Pointer(None); // Data *p = NULL; println!("{}", p.is_none()); // printf(p == NULL ? "true\n" :…

    I built a Cargo-like build tool for C/C++▲177

    I love C and C++, but setting up projects can sometimes be a pain. Every time I wanted to start something new I'd spend the first hour writing CMakeLists.txt, figuring out find_package, copying boilerplate from my last project, and googling why my library isn't linking. By the time the project was actually set up I'd lost all momentum. So, I built Craft - a lightweight build and workflow tool for C and C++. Instead of writing CMake, your project configuration goes in a simple craft.toml: [project] name = "my_app" version = "0.1.0" language = "c" c_standard = 99 [build] type = "executable"…

    Cppmatch – Rust-Like Pattern Matching and Error Handling for C++▲42

    I've created cppmatch, a lightweight, header-only C++ library that brings Rust-inspired pattern matching and error handling to C++. It tries to imitate the functionality of the questionmark (?) operator in C++ by using a macro that uses the gcc extension https://gcc.gnu.org/onlinedocs/gcc/Statement-Exprs.html This allows to create exceptionless code with non-intrusive error-as-value that unlike Exceptions, makes it clear which kinds of error a function can generate and forces you to handle (or ignore) them. The ? operator translates to *expect* To handle the errors I…

    Modifying Clang for a Safer, More Explicit C++▲76

    Modified C++ Inspired by the paper "Some Were Meant for C" by Stephen Kell, I decided to show that it's possible to iterate C++ to be safer, more explicit, and less error-prone. Here's a possible starting point: I didn't invent a new language or compiler, but took the world's best compiler, clang, and modified it to begin iterating towards a new furture of C++. Naming things is hard, so I call this 'Modified C++'. Some of the following could be implemented as tooling in a linter or checker, but the idea is to update the compiler directly. I also wanted to learn more about clang. This…

    I built this software to help users who need to do static code analysis for C/C++ codebase. This can help you to explore the ASTs interactively. It can replace the Clang ast dump completely and also you can search the code/ASTs in a structual way. For example you can search a function which matches specific name or number of paremeters.

    An expression parser supporting multiple types▲33

    This C library is part of a main project aimed at providing a reactive key-value (KV) database. The data is typed (numbers, strings, dates, or booleans) and can include formulas with references to other entries. Clients connected to this database receive a real-time data stream with updates to the subscribed keys, allowing them to react to changes and their dependencies. Essentially, it’s like building a distributed Excel, where data and formulas dynamically update across the system. I couldn’t find any libraries that offered the full set of features I needed for evaluating expressions, so I…
