Sharing iP code quality feedback [for @Eclipse-Dominator] - Round 2

[soc-se-bot-red]

@Eclipse-Dominator We did an automated analysis of your code to detect potential areas to improve the code quality. We are sharing the results below, so that you can avoid similar problems in your tP code (which will be graded more strictly for code quality).

IMPORTANT: Note that the script looked for just a few easy-to-detect problems only, and at-most three example are given i.e., there can be other areas/places to improve.

Aspect: Tab Usage

No easy-to-detect issues 👍

Aspect: Naming boolean variables/methods

Example from src/main/java/duke/command/NoParamCommand.java lines 11-11:

    private boolean invalid;

Suggestion: Follow the given naming convention for boolean variables/methods (e.g., use a boolean-sounding prefix).You may ignore the above if you think the name already follows the convention (the script can report false positives in some cases)

Aspect: Brace Style

No easy-to-detect issues 👍

Aspect: Package Name Style

No easy-to-detect issues 👍

Aspect: Class Name Style

No easy-to-detect issues 👍

Aspect: Dead Code

Example from src/test/java/duke/util/DataParserTest.java lines 53-53:

        // new ParsedData(bye, "b", "c");

Suggestion: Remove dead code from the codebase.

Aspect: Method Length

Example from src/main/java/duke/main/Duke.java lines 139-183:

    public static void main(String[] args) {
        Optional<Boolean> launchWithGui = Optional.empty();
        Optional<String> saveFile = Optional.empty();
        int i = -1;
        while (++i < args.length) {
            switch (LaunchFlagEnum.getFlag(args[i])) {
            case NO_GUI:
                if (launchWithGui.isPresent()) {
                    System.out.println(LaunchFlagErrMsg.CONFLICTING_LAUNCH);
                    return;
                }
                launchWithGui = Optional.of(false);
                break;
            case GUI:
                if (launchWithGui.isPresent()) {
                    System.out.println(LaunchFlagErrMsg.CONFLICTING_LAUNCH);
                    return;
                }
                launchWithGui = Optional.of(true);
                break;
            case SAVE_FILE:
                if (++i == args.length) {
                    System.out.println(LaunchFlagErrMsg.UNSPECIFIED_SAVE_FILE);
                    return;
                }
                saveFile = Optional.of(args[i]);
                break;
            case NULL_FLAG:
                System.out.printf(LaunchFlagErrMsg.UNRECOGNISED_FLAG.toString(), args[i]);
                return;
            case HELP:
                System.out.println(LaunchFlagEnum.getHelp());
                return;
            default:
                System.out.printf(LaunchFlagErrMsg.UNIMPLEMENTED_FLAG.toString(), args[i]);
                return;
            }
        }
        if (launchWithGui.orElse(true)) {
            Launcher.main(saveFile.map(x -> new String[] {x}).orElse(new String[] {}));
            return;
        }
        Duke duke = saveFile.map(x -> createApplication(x)).orElseGet(() -> createApplication());
        duke.run();
    }

Example from src/test/java/duke/util/DataParserTest.java lines 51-106:

    public void dataToCommandTest() {
        ParsedData dummy;
        // new ParsedData(bye, "b", "c");
        for (CommandsEnum c : CommandsEnum.values()) {
            dummy = new ParsedData(c.toString(), "b", "c");
            Command command = DataParser.dataToCommand(dummy);
            assertEquals(command instanceof Command, true);

            if (command instanceof ByeCommand && c == CommandsEnum.BYE) {
                continue;
            }
            if (command instanceof ListCommand && c == CommandsEnum.LIST) {
                continue;
            }
            if (command instanceof MarkCommand && c == CommandsEnum.MARK) {
                continue;
            }
            if (command instanceof UnmarkCommand && c == CommandsEnum.UNMARK) {
                continue;
            }
            if (command instanceof DeleteCommand && c == CommandsEnum.DELETE) {
                continue;
            }
            if (command instanceof TodoCommand && c == CommandsEnum.TODO) {
                continue;
            }
            if (command instanceof DeadlineCommand && c == CommandsEnum.DEADLINE) {
                continue;
            }
            if (command instanceof EventCommand && c == CommandsEnum.EVENT) {
                continue;
            }
            if (command instanceof ByCommand && c == CommandsEnum.BY) {
                continue;
            }
            if (command instanceof FindCommand && c == CommandsEnum.FIND) {
                continue;
            }
            if (command instanceof AliasCommand && c == CommandsEnum.ADDCOMMAND) {
                continue;
            }
            if (command instanceof DeleteAliasCommand && c == CommandsEnum.DELETECOMMAND) {
                continue;
            }
            if (command instanceof SwapFaceCommand && c == CommandsEnum.SWAP) {
                continue;
            }
            if (command instanceof ResetAliasCommand && c == CommandsEnum.RESETALIAS) {
                continue;
            }
            if (command instanceof InvalidCommand && c == CommandsEnum.INVALID) {
                continue;
            }
            fail();
        }
    }

Suggestion: Consider applying SLAP (and other abstraction mechanisms) to shorten methods e.g., extract some code blocks into separate methods. You may ignore this suggestion if you think a longer method is justified in a particular case.

Aspect: Class size

No easy-to-detect issues 👍

Aspect: Header Comments

Example from src/main/java/duke/command/AliasCommand.java lines 20-24:

    /**
     * Create a instance of the deadline command.
     *
     * @param d ParsedData from the command input
     */

Example from src/main/java/duke/command/CommandSelector.java lines 73-77:

    /**
     * Method to get the correct enum based on string version
     *
     * @return returns the Enum for the command
     */

Example from src/main/java/duke/command/DeleteAliasCommand.java lines 18-22:

    /**
     * Create a instance of the deadline command.
     *
     * @param d ParsedData from the command input
     */

Suggestion: Ensure method/class header comments follow the format specified in the coding standard, in particular, the phrasing of the overview statement.
