PDF Scripts Usage Guide

Project Structure

• project.scala - Contains all dependencies for the project
• openpdfzio.sc - Contains the PdfService trait and implementation
• example_usage.sc - Contains examples of how to use PdfService

Running the Examples

Option 1: Run with Scala CLI (Recommended)

# Run the basic example
scala-cli run example_usage.sc --main-class PdfServiceExample

# Run the invoice example  
scala-cli run example_usage.sc --main-class FunctionalPdfExample

# Run the safe example with error handling
scala-cli run example_usage.sc --main-class SafePdfExample

Option 2: Run all files together

# This will compile all .sc files in the directory together
scala-cli run . --main-class PdfServiceExample

Option 3: Compile and run

# Compile first
scala-cli compile .

# Then run
scala-cli run . --main-class PdfServiceExample

How It Works

1. Dependencies: All dependencies are centralized in project.scala
2. Automatic Import: Scala CLI automatically compiles all .sc files in the same directory together
3. PdfService Usage: The PdfService trait and PdfServiceLive implementation from openpdfzio.sc are available in example_usage.sc
4. ZIO Layer: The service is provided via PdfService.live layer

Output

Running any of the examples will create an output.pdf file in the current directory.

Key Points

• No explicit import of openpdfzio.sc needed - Scala CLI handles this automatically
• All using directives are centralized in project.scala to avoid conflicts
• The PdfService uses ZIO for effect management and resource safety
