Intro

Foodbox is a tool designed to make it easy for employees to check the daily lunch menu. The lunch vendor posts the menu on their website as an image, and this project automates the process of sharing that information with everyone. The key features include:

  • Crawling: Fetching the daily menu image from the food vendor's website.
  • OCR Processing: Using Tesseract OCR to extract text from the menu image.
  • Data Structuring: Analyzing and organizing the menu for each date into a structured format.
  • Notification: Sending the lunch menu via a Slack bot at the beginning of each workday, so everyone knows what's for lunch.

The goal is to ensure everyone has quick and easy access to the lunch menu, without needing to search for it manually.

Deployment

Prerequisites

  • Docker
  • Docker Compose
  • Java 21+
  • tesseract-ocr

Configuration

after git clone, make .env file in the same directory as docker-compose.yml and fill in the following values:

SLACK_TOKEN=your_slack_token
SLACK_CHANNEL=#your_slack_channel
CLOVA_URL=your_clova_url_here(general)
CLOVA_SECRET_KEY=your_clova_secret_here

Run

git clone https://github.com/ArgonetDevStudio/foodbox.git
cd foodbox
./gradlew clean build
docker compose up -d

Development Environment Setup

1. Install Tesseract

To extract text from menu images, you'll need to install Tesseract OCR.

MacOS

brew install tesseract

Ubuntu

sudo apt install tesseract-ocr
sudo apt install libtesseract-dev

2. Download Traindata

To improve accuracy for Korean text, download kor.traineddata from tesseract-ocr/tessdata_best and place it in your Tesseract data directory.

3. Note for Apple Silicon Users

If you encounter an UnsatisfiedLinkError related to libtesseract.dylib on macOS with Apple Silicon (M1/M2/M3...), it's likely because the native Tesseract library cannot be found by the Java application. To resolve this, configure your application to tell JNA where to find the Tesseract library:

  1. Option A: In Code Add this line before using Tess4J:

    System.setProperty("jna.library.path", "/opt/homebrew/opt/tesseract/lib");

  2. Option B: In Gradle Build File If you're using Gradle, add the following to your build.gradle:

    test {
    systemProperty "jna.library.path", "/opt/homebrew/opt/tesseract/lib"
}

bootRun {
    systemProperty "jna.library.path", "/opt/homebrew/opt/tesseract/lib"
}
