From edd5dbacd53f544ec151d9886df8104e72c9096c Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 21 Nov 2025 19:51:11 +0000 Subject: [PATCH] Refactor: Maximize self-documentation through comprehensive code modernization MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This refactor dramatically improves code clarity, maintainability, and self-documentation by eliminating boilerplate, removing redundancy, and restructuring logic for transparency. ### New Utility Classes - **Guard.cs**: Centralized parameter validation eliminating 30+ lines of boilerplate - **GitHelper.cs**: Unified Git repository detection (eliminates 2 duplicate implementations) ### New Service Classes (Extracted from Program.cs) - **AppConfig.cs**: Application configuration record (moved to Configuration/) - **ConfigLoader.cs**: JSON configuration loading with error handling - **OutputFormatter.cs**: File output with multiple format support - **StatsCalculator.cs**: Processing statistics calculation - **PathResolver.cs**: Path validation and user input handling - **ContentBuilder.cs**: Project content assembly orchestration ### Code Improvements - **Program.cs**: Reduced from 268 to 71 lines (-73%) with pure DI orchestration - **ProjectScanner.cs**: Uses Guard and GitHelper, improved naming (path → projectPath) - **FileFilterService.cs**: Uses Guard and GitHelper, removed duplicate FindGitRepoRoot - **FileUtilities.cs**: Uses Guard for validation ### Deleted Deprecated Classes - Removed MyAppsContext.cs (obsolete facade) - Removed FileChecker.cs (obsolete facade) - Removed FileUtils.cs (obsolete facade) ### Self-Documentation Improvements - Consistent parameter naming (projectPath vs path/rootPath) - Clear variable names (structure, fileContents vs sb, results) - Expressive method extraction (single responsibility) - Pure dependency injection (no static facades) - Obvious data flow through constructor injection ### Impact - 8 new focused classes with single responsibilities - Eliminated all validation boilerplate through Guard - Removed all code duplication (Git helpers, validation) - Program.cs is now pure orchestration (73% reduction) - Clear, testable, maintainable architecture - Zero functional changes - backward compatible --- Configuration/AppConfig.cs | 13 ++ FileChecker.cs | 26 ---- FileUtils.cs | 21 --- MyAppsContext.cs | 56 ------- Program.cs | 274 +++++----------------------------- Services/ConfigLoader.cs | 34 +++++ Services/ContentBuilder.cs | 42 ++++++ Services/FileFilterService.cs | 50 ++----- Services/OutputFormatter.cs | 63 ++++++++ Services/PathResolver.cs | 96 ++++++++++++ Services/ProjectScanner.cs | 90 +++-------- Services/StatsCalculator.cs | 36 +++++ Utils/FileUtilities.cs | 9 +- Utils/GitHelper.cs | 42 ++++++ Utils/Guard.cs | 76 ++++++++++ 15 files changed, 475 insertions(+), 453 deletions(-) create mode 100644 Configuration/AppConfig.cs delete mode 100644 FileChecker.cs delete mode 100644 FileUtils.cs delete mode 100644 MyAppsContext.cs create mode 100644 Services/ConfigLoader.cs create mode 100644 Services/ContentBuilder.cs create mode 100644 Services/OutputFormatter.cs create mode 100644 Services/PathResolver.cs create mode 100644 Services/StatsCalculator.cs create mode 100644 Utils/GitHelper.cs create mode 100644 Utils/Guard.cs diff --git a/Configuration/AppConfig.cs b/Configuration/AppConfig.cs new file mode 100644 index 0000000..eecabc6 --- /dev/null +++ b/Configuration/AppConfig.cs @@ -0,0 +1,13 @@ +namespace CodeContext.Configuration;
