pystring

A Python-style string manipulation library in modern C++.

• Python-like slicing: s(1, 4) → "bcd"
• Negative indices
• +, *, ==, [] operators
• split(), join(), strip(), startswith(), endswith(), count()
• Prefix/suffix checks: starts_with(), ends_with()
• Substring counting: count("na") → 2

Installation

1. Clone pystring into your own project directory:

git clone https://github.com/gowthaman-01/pystring.git

2. Your project structure might look like:

your_project/
├── CMakeLists.txt
├── main.cpp
└── pystring/              ← cloned here

3. In your own CMakeLists.txt, add these lines to build your app and link pystring:

add_executable(my_app main.cpp)

add_subdirectory(pystring)
target_link_libraries(my_app PRIVATE pystring::pystring)

💡 Replace my_app with the name of your own CMake executable target.

⚠️ Warning

This library uses modern C++ features like if constexpr and std::is_arithmetic_v, so you must enable C++17 in your project:

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

If you don’t, you may get errors like:

error: no template named 'is_arithmetic_v' in namespace 'std'

Usage

See docs/usage.md for more detailed examples.

#include <pystring.hpp>

int main() {
    pystring s("hello world");
    auto sliced = s(0, 5);
    std::cout << sliced.get() << "\n";    // "hello"
}
