So-called "L" blocks: snap-on else & else if

DaEpikDude

I had a random thought.
We're all familiar with the blocks if and if…else, right?
And we presumably know that you can put an if inside of else to make an else if.
I had a random idea where below the “if” c block, you have an “else if” ‘L’ block and an “else” ‘L’ block.
They snap onto exclusively the “if” block, and sort of extend it, so if you have 10 else ifs, it isn't horribly indented by the end.
Basic idea…

if <> then //Default if block
...
end

else{
...}::control//New snap-on else

else if <> then{
...}::control//New else if

//Example:
if <foo> then
...
end 
else if <bar> then{
...}::control//Presumably these would blend together better

The idea is that you attach the else and else if onto the if, and it makes it one big block all on the same line, instead of it gradually becoming further and further right the more else ifs you add.
Sorry if I didn't explain this very well, it's just a random idea that popped into my head.

I don't see a problem with just using the If else block we already have. No support.

Semi-support? While I would definitely find this useful for the cases where I don't think I need an else, it may come off as confusing.

I understand that, but sometimes it's annoying when you have lots of else if's.
For example:

if <> then 
...
else
if <> then 
...
else
if <> then 
...
else
if <> then 
...
else
...//See how far right this goes after just 4 else if's?
end
end
end
end

Sometimes all those indents get pretty annoying.

Yeah, I'm not sure how to introduce the concept properly, or how to explain that they can only attach to if's and so on.

No Support. This could cause confusion. However, I believe there would be another way to do this. There would be this option to expend an “if, then, else” block by a certain amount just by right clicking it. Like if you want 3 else block inputs, right click on it, choose the option called “Expand”, it will tell you how much you have, but can only have a minimum of 10 though. Since the example is 3 blocks, type 3, to get this:

if <> then {
} else {
} else {
} else {
} :: control

Agree with expand!

Support. I like this creativity for new ideas on how to do Scratch blocks. And because they would be labelled, it would be clear what the blocks do. The only trick is coming up with a reliable visual grammar for the new snap on.

Ooh, yeah, I like the idea of expanding an if…else statement. My only problem is that shouldn't they become else if's instead of else's?

Yeah, the visuals is the main problem with my idea…

I don't see this as annoying, but rather as a way to easily identify which block is which. It's also more similar to some other text based languages. For example, you can't do this:

if <>
else
if <>
else
if <>
else
if <>
else
if <>
else
end
end
end
end
end

You have to do this:

So you can know exactly where each loop ends.

Fair enough, but I think they're both ways of telling where the statement ends: in the Scratch form, the first “else” contains every other else statement, rather than the other form where they are sequential. It really just depends on how you think of it: do you think they should be sequential, or do you think the first statement should contain all the other ones?
Side note: there are languages where they're sequential, for example C++:

if (so and so) {
    ...
} else if (such and such) {
    ...
} else if (whatever) {
    ...
} else {
    ....
}

Not sure what language you're talking about, but the other languages I've seen (all 3 of them) are all sequential.

Ok, I thought so.
Also I'm assuming you meant maximum, not minimum.
My only other problem with your idea is what if you have like 10 else if's and you realise you have one too many? Unless there's a delete button for the extensions, it'd be really inconvenient to have to make another 9-long thing if you accidentally put one too many.
