OussamaMater / Programming-Language-Recommendation-Expert-System

An Expert System to help you pick a programming language.

Project Setup Guide

Overview

An Expert System that suggests the most suitable programming language based on your interests and preferences.

The system is built with Laravel, Livewire, FastAPI, and Experta.

Manual Setup

You can avoid this configurational step by using the Docker installation process.

Before setting up the project, make sure you have the required dependencies:

• Python >= 3.9
• PHP >= 8.0
• pip
• composer
• npm

Installing Dependencies

The following example works for Debian Based Linux Distributions.

Update the system

sudo apt update && sudo apt upgrade -y

Install Python

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt install python3.9

Install pip

sudo apt install python3-pip

Install PHP

sudo apt get install -y php8.1-cli php8.1-common php8.1-mysql php8.1-zip php8.1-gd php8.1-mbstring php8.1-curl php8.1-xml php8.1-bcmath

Install composer

curl -sS https://getcomposer.org/installer -o /tmp/composer-setup.php

sudo php /tmp/composer-setup.php --install-dir=/usr/local/bin --filename=composer

Install npm

sudo apt install nodejs npm

Setting the Web Application

Make sure you are in the web-app directory

cd src/web-app

Install composer dependencies

composer install

Install npm dependencies and build the assets

npm install
npm run build

Create the .env file and generate the application encryption key

cp .env.example .env
php artisan key:generate

Update the package.json file by swapping the scripts section with the one below

"scripts": {
    "dev": "vite",
    "build": "vite build"
},

Update the expert.php config file

'endpoint' => 'http://localhost:5500/detect',

Setting the Expert System

Install all the requirements

pip install --no-cache-dir --upgrade -r dockerfiles/expert-system/requirements.txt

Running the project

Start the expert system

python main.py

Start the built-in web server

php artisan serve

You can now access the server at http://localhost:8000.

Docker Setup

Make sure Docker is installed.

If you are using a Windows 10/11, you need to know that Windows uses WSL (Windows Subsystem for Linux), which is a layer between Windows and Linux, this makes Docker slow and browser requests may take 30-60 seconds to be completed.

Spin up the containers

docker-compose up -d --build app

Running the command will expose 3 services with the following ports:

• Nginx - :80
• PHP - :9000
• FastAPI - :5500

Install composer dependencies

docker-compose run --rm composer install

Install npm dependencies and build the assets

docker-compose run --rm npm install
docker-compose run --rm --service-ports npm run build

Create the .env file and generate the application encryption key

cp .env.example .env
docker-compose run --rm php artisan key:generate

You can now access the server at http://localhost.

Configuration

Add Questions

You can add questions to help get better results by editing the src/web-app/questions.json file.

A question is a json object that has two fields:

• "question": The question displayed to the user.
• "fact": The information sent to the system to reason about the problem in case the user answers with "yes".

"18": {
    "question": "You want to code to build websites?",
    "fact": "web"
}

Add Languages

You can add new languages to be displayed to the user as a result by editing the src/web-app/languages.json file.

Make sure you have a rule that leads to the newly defined language using the facts you have, otherwise it will never be displayed, to do so, edit the src/expert-system/expert.py and follow the docs here.

A language is a json object that has three fields:

• "logo": The filename of the language's logo placed in src/web-app/resources/images.
• "description": A brief description about the language.
• "infos": A link for more insightful information about the language.

"c/c++": {
    "logo": "c-logo.png",
    "description": "C++ is a powerful general-purpose programming language. It can be used to develop operating systems, browsers, games, and so on.",
    "infos": "https://www.programiz.com/cpp-programming"
}
