defmodule UmyaSpreadsheet do
  @moduledoc """
  UmyaSpreadsheet is an Elixir wrapper for the Rust `umya-spreadsheet` library,
  which provides Excel (.xlsx, .xlsm) file manipulation capabilities with the
  performance benefits of Rust.

  ## Overview

  This library allows you to:
  - Create new spreadsheets from scratch
  - Read/write Excel files with full formatting support
  - Manipulate cell values, formulas, and styles
  - Move and organize ranges of data
  - Add and manage multiple worksheets
  - Create charts, images, and visual elements
  - Embed OLE objects (Word documents, PowerPoint presentations, etc.)
  - Add data validation and conditional formatting
  - Export to CSV with performance optimizations
  - Apply advanced formatting and styling options

  ## Architecture

  UmyaSpreadsheet follows a modular architecture with specialized function modules:

  ### Core Architecture

  ```
  UmyaSpreadsheet (Main Module)
  ├── UmyaNative (Rust NIF Interface)
  │   ├── Spreadsheet Operations (new, read, write)
  │   ├── Cell Operations (get/set values, formatting)
  │   ├── Sheet Management (add, remove, rename)
  │   └── Native Rust Library (umya-spreadsheet)
  │

      └── WindowFunctions - View settings and window management
  ```

  ### Data Flow

  1. **NIF Layer**: All operations go through the native interface which interfaces with Rust
  2. **Spreadsheet Reference**: Operations work on a Rust-managed spreadsheet reference
  3. **Function Modules**: Specialized modules provide domain-specific functionality
  4. **Error Handling**: Comprehensive error handling with descriptive messages
  5. **Memory Management**: Rust handles memory management for performance

  ### Thread Safety

  The library is designed for concurrent operations:
  - Each spreadsheet maintains its own Rust reference
  - Multiple spreadsheets can be operated on simultaneously
  - Thread-safe patterns are documented in the guides

  ## Performance Characteristics

  - **Memory Efficient**: Rust memory management with minimal Elixir overhead
  - **Fast I/O**: Native Rust file operations for reading/writing
  - **Lazy Loading**: Optional lazy reading for large files
  - **Light Writers**: Memory-optimized writers for simple operations
  - **Concurrent Safe**: Multiple processes can work with different spreadsheets

  ## Compatibility

  - **Excel Versions**: Full support for Excel 2007+ (.xlsx, .xlsm formats)
  - **Elixir Versions**: Compatible with Elixir 1.12+
  - **OTP Versions**: Compatible with OTP 24+
  - **Platforms**: Linux, macOS, Windows (via precompiled NIFs)

  ## Quick Start

      # Create a new spreadsheet
      {:ok, spreadsheet} = UmyaSpreadsheet.new()

      # Set some cell values
      UmyaSpreadsheet.set_cell_value(spreadsheet, "Sheet1", "A1", "Hello")
      UmyaSpreadsheet.set_cell_value(spreadsheet, "Sheet1", "B1", "World")

      # Apply formatting
      UmyaSpreadsheet.set_font_bold(spreadsheet, "Sheet1", "A1", true)
      UmyaSpreadsheet.set_background_color(spreadsheet, "Sheet1", "A1", "#FF0000")

      # Write to file
      UmyaSpreadsheet.write(spreadsheet, "example.xlsx")

  ## Error Handling

  Most functions return either `:ok` or `{:error, reason}` tuples. Common error patterns:

      case UmyaSpreadsheet.set_cell_value(spreadsheet, "NonExistent", "A1", "value") do
        :ok -> IO.puts("Success!")
        {:error, reason} -> IO.puts("Error: \#{inspect(reason)}")
      end
