PString: A C++ String Library with Python-style Operations

PString is a C++ string library designed to emulate the behavior and functionality of Python's str type. Developed as a modified component of the sapy project.

Install

git clone https://github.com/EPTansuo/PString
cd PString && mkdir build && cd build
cmake .. -DCMAKE_INSTALL_PREFIX=/usr
make && sudo make install 

Example

demo.cpp:

#include <iostream>
#include <pstring.h>

int main(){
    PString str = "  Hello, World!  ";

    // Python-style split
    auto str_split = str.split(",");
    std::cout << str_split[0].upper() << std::endl;
    
    // Python-style join
    auto str_joined = PString(":").join(str_split);
    std::cout << str_joined << std::endl;

    // Python-style slice
    auto str_sliced = str.slice(6, 1, -1);
    std::cout << str_sliced << std::endl;

    // Python-style strip
    auto str_stripped = str.strip();
    std::cout << str_stripped << std::endl;

    // ...
}

Compile and run:

g++ demo.cpp -lpstring -o demo
./demo
