SeConv Implementation Summary

What Was Built

A modern, well-structured command-line utility for subtitle conversion with:

✅ Features Implemented

1. Modern CLI Framework

   • Using Spectre.Console and Spectre.Console.Cli for a professional CLI experience
   • Colored output with beautiful tables, panels, and formatting
   • Animated spinners during processing
   • Legacy / parameter support converted to modern -- syntax

2. Command Structure

   • convert command - Main conversion functionality with all specified parameters
   • formats command - Lists all available subtitle formats
   • Help system with /?, /help, or --help

3. All Specified Parameters Supported

   • File operations: --inputfolder, --outputfolder, --outputfilename, --overwrite
   • Format options: --encoding, --fps, --targetfps, --resolution
   • Advanced options: --assa-style-file, --ebuheaderfile, --pac-codepage, etc.
   • All processing operations: --FixCommonErrors, --RemoveTextForHI, --SplitLongLines, etc.

4. Clean Architecture

Project Structure

Files Created

1. Commands/ConvertCommand.cs - Main conversion command with all parameters
2. Commands/FormatsCommand.cs - Lists available subtitle formats
3. Core/SubtitleConverter.cs - Core conversion logic (stub)
4. Core/LibSEIntegration.cs - Integration layer with LibSE library (stub)
5. Helpers/HelpDisplay.cs - Beautiful help text display
6. Program.cs - Application entry point with CLI setup
7. README.md - Full documentation

Dependencies Added

• Spectre.Console 0.54.0 - Console UI framework
• Spectre.Console.Cli 0.53.1 - Command-line parsing

Next Steps for Integration

To complete the implementation, integrate with the LibSE library:

1. In LibSEIntegration.cs:

   • Implement GetAvailableFormats() using LibSE's format registry
   • Implement LoadSubtitle() to load subtitle files
   • Implement SaveSubtitle() to save in target format
   • Implement ApplyOperations() for all processing operations

2. In SubtitleConverter.cs:

   • Use LibSEIntegration to load, process, and save subtitles
   • Add proper error handling and progress reporting
   • Implement batch processing for multiple files

3. Testing:

   • Test with real subtitle files
   • Verify all operations work correctly
   • Add unit tests

Usage Examples

# Show help
dotnet run --project SeConv/SeConv.csproj -- --help

# List formats
dotnet run --project SeConv/SeConv.csproj -- formats

# Convert subtitles
dotnet run --project SeConv/SeConv.csproj -- convert *.srt sami

# Convert with options
dotnet run --project SeConv/SeConv.csproj -- convert *.srt subrip --encoding:utf-8 --FixCommonErrors --RemoveTextForHI

# Legacy syntax support
dotnet run --project SeConv/SeConv.csproj -- /convert *.srt sami /encoding:utf-8

Key Design Decisions

1. Spectre.Console - Provides modern, colorful CLI experience out of the box
2. Stub architecture - All integration points clearly marked with TODO comments
3. Backward compatibility - Legacy / syntax automatically converted to -- syntax
4. Extensibility - Easy to add new commands and operations
5. Type safety - Strong typing with command settings classes

Color Output Examples

• ✅ Green for success messages
• ❌ Red for errors
• 💡 Yellow for parameters/options
• 🔵 Cyan for headings
• ⚙️ Animated spinners during processing
• 📊 Beautiful tables for data display
