Fibonacci Calculator

Overview

The Fibonacci Calculator is a cross-platform desktop application built using Rust and Tauri. It allows users to input a number and computes its Fibonacci value,

Features

• User friendly interface with an input field and a button to calculate fibonacci numbers.
• Error handling to ensure only valid numbers are processed.
• Built with Rust for performance and reliability.
• Utilizes Tauri for a lightweight desktop application.

Setup Instructions

1. Clone the repository:

   git clone https://github.com/micheal-ndoh/Fibonacci_app.git
   cd fibonacci-app

2. Install Rust and Tauri: Ensure you have Rust installed. Follow the instructions on the Rust website to install Rust. Then, install Tauri by following the Tauri setup guide.

   Install rust using:

   curl --proto '=https' --tlsv1.2 https://sh.rustup.rs -sSf | sh

   If it fails then try installing the dependencies manually and install rust again:

   sudo apt update
   sudo apt install libwebkit2gtk-4.0-dev \
   build-essential \
   curl \
   wget \
   file \
   libssl-dev \
   libgtk-3-dev \
   libayatana-appindicator3-dev \
   librsvg2-dev

   Install tauri using:

   cargo install tauri-cli

3. Install frontend dependencies: Navigate to the src directory and run:

   npm install

4. Run the application: From the src tauri directory, run:

   cargo tauri dev

   alternatively

   npm run tauri dev

5. Build the application: From the src directory, run:

   cargo tauri build

   alternatively

   npm run tauri build

6. Run the application: Navigate to the src-tauri/target/release directory and run the generated executable.

   ./fibonacci-calculator

...

7. Package the application: Firstly list all the targets for which you want to build the application using and install the one you wish to using to build the application.

   rustup target list

   Install/add using

   rustup target add <name of target>

   Then from the src directory, run the following commands for each target:

   For macOS (.dmg):

   cargo tauri build --target x86_64-apple-darwin

   For Windows (.exe):

   cargo tauri build --target x86_64-pc-windows-gnu

   For Linux (.AppImage):

   cargo tauri build --target x86_64-unknown-linux-gnu

8. Install the application on Linux: Ensure all required dependencies are installed:

   sudo apt update
   sudo apt --fix-broken install
   sudo apt install libwebkit2gtk-4.1-0 libgtk-3-0

   Then install the .deb , rpm or appimage package use the following command:

   sudo dpkg -i fibonacci-calculator_0.1.0_amd64.deb

   sudo rpm -i fibonacci-calculator-0.1.0.x86_64.rpm

   Make the appimage executable and run;

   sudo chmod +x fibonacci-calculator.AppImage
   ./fibonacci-calculator.AppImage

9. Install the application on Windows: Run the .exe file.

10. Install the application on macOS: Run the .dmg file.

Usage

• Enter a number in the input field and click the "Calculate" button to calculate the Fibonacci number.
• The result will be displayed below the input field.
• You can input multiple numbers in sequence but separate them by commas.

Error Handling

The application ensures that only valid numbers are processed and if an invalid number is entered, an error message is displayed but it was handle so that the user can try again by entering a valid number.

Bonus Features

• Added multiple calculation feature to compute multiple Fibonacci numbers in sequence.
• This application can be packaged as an installable .exe, .dmg, or .AppImage.
• The application can be optimized for performance.
• The application can be distributed as a desktop application.

TODO

• Add more features to the application.
• Optimize the application for performance.
• optimize the application for size.
• Add more languages to the application.
• Add an icon for the application.

DONE

• Add more themes to the application.
