LittleMissHelpful

“Your mind is for having ideas, not holding them.” – David Allen

Ah Bang Mang frees your mind from remembering the things you need to do. It's:

Text-based
Easy to learn
SUPER FAST to use
Singlish Ui

All you need to do is:

Download it from here.
Double-click it.
Add your tasks.
Let it manage your tasks for you 😉.

And the best part? It’s FREE!

Features:

Managing tasks
Managing deadlines (coming soon)
Reminders (coming soon)

If you are a Java programmer, you can use LittleMissHelpful to practice Java too! Here's the main method:

public static void main(String[] args) {
        new LittleMissHelpful("data/LittleMissHelpful.txt").run();
    }

In build.gradle, the dependencies on distZip and/or distTar causes the shadowJar task to generate a second JAR file for which the mainClass.set("seedu.duke.Duke") does not take effect. Hence, this additional JAR file cannot be run. For this product, there is no need to generate a second JAR file to begin with. Let's remove this dependency from the build.gradle to prevent the shadowJar task from generating the extra JAR file.

Would it be better to refactor this part into the the Parse class as suggested in the project brief week 3?

agreed! Separating all the parsing commands into a separate parse class could make the code look neater

Yes, thank you! I have abstracted out the classes now

This check looks the same as the check for the "mark" command, perhaps can refactor to reduce repetition?

The switch and case statement may come in handy here. (frankly I also never use)

Perhaps can provide some descriptions of what are valid commands

Maybe you can add this comment in the header instead? (i.e. before the public class in Line 10) It may help others to understand your code purpose better!

An idea is that you could make this into an abstract class and have the different methods for the different classes in their respective class files! It's just an alternative way to do it that you can consider.

frymash

In general, I think your code is really well-organised and well-abstracted. This is the first time I've seen someone create a Java file for each command. I also like the vibes your bot's responses give. Good job! LGTM.

Small suggestion involving code consistency but I noticed some files have a line of space between the package statement and the import statement while other files don't. The course's coding standard doesn't really prescribe a set way to go about this, but perhaps you could consider either using one or the other.

Thank you for your feedback! I'll be sure to edit this

Good practice to make the divider a constant so that you don't have to repeat yourself whenever you use it.

Could possibly refactor the if-else statement into a switch-case statement (not 100% necessary but a suggestion).

Was wondering if the switch-case syntax would be more idiomatic here too

Overall LGTM! The naming for class , method and variables is well done and convey their purposes clear!

Would be nice if header comments could be added to class and the public method as part of JavaDoc!
