Walkthrough

Refactors MyCMD from a CLI shell to a JavaFX GUI application. Updates Maven configuration with JavaFX dependencies and plugins, adds GitHub Actions CI/CD workflow, introduces new GUI components (MainApp, TerminalController) with FXML layout and CSS styling, reorganizes build scripts, creates launcher scripts, and simplifies the shell infrastructure with updated core classes.

Changes

Cohort / File(s)	Summary
CI/CD Pipeline .github/workflows/build.yml	Introduces GitHub Actions workflow triggering on push/PR to main, building with Maven and uploading JAR artifacts.
Build Configuration pom.xml, mvnw, mvnw.cmd	Reconfigures Maven project: renames artifactId to MyCMD-GUI, updates version to 1.0.0, replaces Lombok with JavaFX 21 dependencies, updates compiler plugin, replaces jar/spotless plugins with javafx-maven-plugin and maven-shade-plugin; adds Maven wrapper scripts.
Build Scripts scripts/build-linux.sh, scripts/build-windows.bat	Simplifies build process: switches from mvn to ./mvnw/mvnw.cmd, removes multi-step packaging/jpackage logic, outputs single JAR to dist/MyCMD-GUI.jar.
Project Structure .gitignore, lib/.gitkeep, launcher/MyCMD.bat	Expands .gitignore patterns for IDE/build artifacts; adds lib directory placeholder; adds Windows batch launcher setting MYCMD_LAUNCHED env var and launching JAR via javaw.
Shell Infrastructure src/main/java/com/mycmd/Command.java, src/main/java/com/mycmd/CommandRegistry.java, src/main/java/com/mycmd/ShellContext.java, src/main/java/com/mycmd/ShellEngine.java, src/main/java/com/mycmd/StringUtils.java	Refactors core: makes Command's description() and usage() abstract; introduces CommandRegistry for command lookup; simplifies ShellContext to manage only directory and aliases; adds ShellEngine for command execution with error handling; replaces StringUtils Levenshtein logic with simple isEmpty() and join() utilities.
Entry Points src/main/java/com/mycmd/App.java, src/main/java/com/mycmd/ConsoleShell.java	Redirects App.main to launch JavaFX GUI via Application.launch(MainApp.class) with launcher environment check; adds ConsoleShell for developer REPL-like console access.
GUI Components src/main/java/com/mycmd/gui/MainApp.java, src/main/java/com/mycmd/gui/TerminalController.java	Introduces MainApp extending Application to initialize shell components, register built-in commands, load FXML, and configure Stage; adds TerminalController to manage terminal UI with input field, output area, and Enter key handler for command execution.
GUI Resources src/main/resources/com/mycmd/gui/terminal.fxml, src/main/resources/com/mycmd/gui/style.css	Defines FXML layout: AnchorPane with VBox containing TextArea (output) and HBox with prompt label and TextField (input); defines dark CSS theme with cyan accents, Jetbrains Mono font, and gradient background.
Configuration src/main/resources/com/mycmd/config/default.properties	Adds application defaults: name, version, author, dark theme, font size, accent color, background image, default directory, shell history settings.

Estimated code review effort

🎯 4 (Complex) | ⏱️ ~45 minutes

Areas requiring extra attention:

• pom.xml refactoring: Verify JavaFX version compatibility, Maven plugin configurations (javafx-maven-plugin, maven-shade-plugin), and ensure manifest transformer correctly sets the mainClass.
• App.java security check: Validate the MYCMD_LAUNCHED environment variable logic and confirm it properly enforces launcher-only execution.
• ShellContext simplification: Review the removal of history, scanner, and environment variable management to ensure no critical functionality is lost and null/invalid directory checks are sufficient.
• ShellEngine error handling: Confirm IOException handling and unknown command messaging are appropriate for the GUI context.
• JavaFX integration: Verify FXML controller injection, stage initialization, and event handler setup in TerminalController and MainApp are correct.
• Build script changes: Confirm Maven Wrapper invocation works on both Linux and Windows, and that dist directory structure meets deployment requirements.

Poem

🐰 From CLI's command line, we hop to the GUI,
With JavaFX styling under a futuristic sky,
Dark theme and cyan glow, a shell refined,
Build scripts simplified, clean and designed,
MyCMD dances forward, refactored with pride! 🚀
