[Discontinued] ListAddon Extension

`ListAddon Extension`

This extension allows for doing more things with App Inventor Lists. I made this extension with Kodular IDE.

Current version: 1
Release date: 2019-04-21T21:00:00Z
Required permissions: none
Min API required: N/A

I decided the build this extension because I saw we can actually do more things with YailList (a Java object which used in App Inventor for lists.) So I created additional blocks for the built-in list blocks.

`Blocks`

Block Name	Description	Required List Type
BubbleSort	Return a list which sorted by Bubble sorting algorithm.	Number
MinimumNumber	Return minimum number in list.	Number
MaximumNumber	Return maximum number in list.	Number
SimpleSort	Return a sorted list for list which contains strings instead of numbers.	String
Compare	Returns `true` if input lists are same. If not, result will be `false`.	All
GetLastItem	Return last item from any list. It can be useful if you have dynamic list.	All
ToJSONString	Return a strictly syntactically correct JSON text representation of list.	All
Reverse*	Return a reversed list.	All

I wanted to make a universal extension which will work in all App Inventor distros. So maybe we can have “reverse list” block, but other distros still may not have. That’s why I added this block to the extension.
I didn’t add sorting option because you can already have descending sorting by reversing sorted list.

I hope you like it! Don’t forget to report the problems. I will try to do my best to improve this extension.

(by the way I love direct links)

Wow nice one

Btw, It’s like this Extension builder should represent their extensions

Thanks for this very useful extension. In this extension sorting order is available in ascending and better if you implement also in descending order.

Souvik_Bera · April 23, 2019, 2:24am

@7StarMedia The list utils extension by appybuilder also does support descending shorting.

yusufcihan · April 23, 2019, 8:28am

I didn’t add sorting option because you can reverse sorted list then you will have descending sorting.

Maybe I can add sorting option, but this will only increase extension size since you can already select the sorting option.

Can you add sort option for list in list structure?

Liste içinde liste tipi için destek ekleyebilirmisin? Mesela

Liste item1(isim1,isim2,isim3)
item2 (puan1,puan2,puan3)
item3(ekstrabilgi1,e2,e3)

gibi bir listeyi belli bir item e göre sıralasın mesela en yüksek puana sahip olan puan2 ise isim2 ve e2 yi birinci eleman olarak geri döndürsün gibi.

Göz atmam lazım. Aslında belki bunu mantık ve bloklarla yapabilirsin ancak tam emin değilim.

I need to take a look at it. Maybe actually you can do with logic and blocks, but I’m not sure.

Ali_Aydin · April 23, 2019, 10:25pm

I already do it with blocks but if i can do it with extension its make easier.

Bloklarla yaptım lakin eklenti olması daha çok işime gelir

Thanks, (for like and for video) yeah as I said you can revert sorting with “Reverse” block.

Also you don’t need to create new variable for that. You can use Reverse block with Sort directly. Just connect purple block with purple block.

link not work for me …

yusufcihan · September 22, 2019, 7:38am

Thanks for reporting! I fixed it. For preventing the upcoming community download errors, I hosted the file on my website. (Don’t worry, it is a direct download link too )

I’m getting an odd issue. I’m sorting a list of names alphabetically using the SimpleSort method and names that have been entered without capitalization get sorted to the bottom of the list. Is there a way to sort it without taking capitalization into account?

yusufcihan · January 31, 2020, 12:39pm

As I sort items with Java’s own Sort method, it is case sensitive. I can add a method for that when Kodular IDE becomes online again.

You can lowercase your all list items as a workaround.

GaryH · January 31, 2020, 2:11pm

I added the TextBoxTools extension to set the box to capitalized words so that it should result in the names being formatted correctly. Hopefully, that solves the issue unless my users intentionally screw it up. Which, to be realistic, they probably will.

Hi. How to sort

Banana
Water Melon
Apple
Custard Apple

to

Banana
Custard Apple
Apple
Water Melon

Up to 9 I seems it is possible, But if number increases to double digit or more
the result is not as expected.

I tried for 21 Numbers in this way. The result is as following.

The result is coming like this
9. xxxx
8. xxxx
7. xxxx
6. xxxx
5. xxxx
4. xxxx
3. xxxx
21. xxxx
20. xxxx
2. xxxx
19. xxxx
18. xxxx
17. xxxx
16. xxxx
15. xxxx
14. xxxx
13. xxxx
12. xxxx
11. xxxx
10. xxxx

xxxx
