PDFBox Crystal

A Crystal language port of Apache PDFBox - an open-source library for working with PDF documents.

About Apache PDFBox

Apache PDFBox is a Java library that allows:

• Creation of new PDF documents
• Manipulation of existing PDF documents
• Extraction of content from PDF documents
• Command-line utilities for PDF operations

This Crystal port aims to bring the powerful PDF manipulation capabilities of Apache PDFBox to the Crystal programming language.

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     pdfbox:
       github: dsisnero/pdfbox

2. Run shards install

Usage

require "pdfbox"

# TODO: Add Crystal-specific usage examples
# This will include PDF creation, manipulation, and content extraction

Development

This project follows Crystal development best practices and includes a Makefile for common tasks:

Using the Makefile

make help              # Show all available commands
make submodule-init    # Initialize Apache PDFBox submodule
make submodule-update  # Update Apache PDFBox submodule to latest
make deps              # Install Crystal dependencies
make format            # Format Crystal code
make lint              # Run Crystal linter (ameba)
make lint-fix          # Run Crystal linter and fix issues
make test              # Run Crystal tests
make quality           # Run all quality checks (format, lint, test)
make clean             # Clean build artifacts

Manual Commands

crystal tool format    # Format Crystal code
ameba                  # Run Crystal linter
ameba --fix            # Fix Crystal linting issues automatically
crystal spec           # Run all tests
shards install         # Install dependencies
shards update          # Update dependencies
