BoltUI ⚡

BoltUI simplifies the creation of graphical user interfaces (GUIs) in C++ by redirecting program output to a web-based interface. This package aims to provide a seamless experience for new C++ developers by replacing iostream functionalities like cout and cin with web-based UI components.

Why Use BoltUI?

• Simplified UI Creation: Easily redirect C++ output to a web interface.

• Cross-Platform: With WebAssembly, your BoltUI program can run across all modern browsers.

• Developer-Friendly: Reduce friction for new C++ developers entering the realm of GUI development.

• Rich Outputs: Incorporate images, markdown formatting, and user interactions within the C++ program output.

🛠️ Installation

Prerequisites

1. Emscripten: Install Emscripten to compile C++ to WebAssembly.

Steps

1. Clone the Repository: git clone https://github.com/LehuyH/boltui.git

2. Include boltui.hpp: Add #include "boltui.hpp" in your C++ project.

🚀 Quick Start Example

#include "boltui.hpp"

using namespace std;

int main(){
  UI ui;

  ui << ui.markdown("# Hello, welcome to the Cat Shop!");

  ui << ui.markdown("## Who do you want to adopt ?");

  ui.font("monospace");
  ui << ui.setw(20) << "Whiskers" << ui.setw(20) <<
  ui.image("http://placekitten.com/300/200") 
  << endl;

  ui << endl << endl << endl;

  ui << ui.setw(20) << "Meowtastic" << ui.setw(20) <<
  ui.image("http://placekitten.com/200/200") 
  << endl;

  ui << endl << endl << endl;
  ui.font("sans");

  return 0;

}

🧰 Usage

BoltUI provides a set of functionalities to streamline C++ console output and interaction. First create a new instance of the UI class like so:

UI ui;

Now, you can use all of BoltUI's feature. Here are some common functions and their usage:

Output Functions

• UI& operator<<(const std::string& input): Outputs a string to the UI.

  ui << "Hello, World!";

• UI& operator<<(int input): Outputs an integer to the UI.

  int num = 42;
  ui << num;

• UI& operator<<(float input): Outputs a float number to the UI.

  float value = 3.14f;
  ui << value;

• UI& operator<<(bool input): Outputs a boolean value to the UI.

  bool status = true;
  ui << status;

Input Functions

• UI& operator>>(std::string& input): Reads a line of text from the UI.

  string userInput;
  ui >> userInput;

• UI& operator>>(int& num): Reads an integer value from the UI.

  int number;
  ui >> number;

• UI& operator>>(float& num): Reads a float value from the UI.

  float value;
  ui >> value;

• UI& operator>>(bool& num): Reads a boolean value from the UI.

  bool status;
  ui >> status;

Formatting Functions

• UI& setw(int width): Sets the field width for the next output.

  ui.setw(10) << "Field Width";

• UI& setfill(const std::string& input): Sets the fill character for the next output.

  ui.setfill('*') << "Filled Text";

• UI& getline(std::string& input): Reads a line of text from the UI and stores it in the given string.

  string userInput;
  ui.getline(userInput);

Special Functions

• UI& markdown(std::string input): Renders a Markdown-formatted string in the UI.

  ui.markdown("# Title\n## Subtitle\n- Bullet point 1\n- Bullet point 2");

• UI& image(std::string input): Displays an image in the UI using its URL.

  ui.image("https://example.com/image.png");

🔨 Build

To compile and build your C++ code with BoltUI, follow these steps:

1. Run the following command in your terminal:

em++ boltui.cpp (ADD OTHER SOURCE FILES HERE) -s WASM=1 -o ./dist/main.js -s EXPORTED_RUNTIME_METHODS=getValue -s NO_EXIT_RUNTIME=1 -s DEFAULT_LIBRARY_FUNCS_TO_INCLUDE='$stringToNewUTF8' -s ASYNCIFY

Replace (ADD OTHER SOURCE FILES HERE) with any additional source files your project requires.

2. This command will generate the necessary output in the ./dist directory.

3. You can then upload the contents of the ./dist folder to any static hosting service to run your application.
