2. Callbacks are not shown in autocomplete:

We are working on a fix for this as well.

Hey! I’m not sure on whether this is the right place for this as I don’t have access to the bugs category, but I’d like to point out an issue with the APIs for task.spawn & task.defer erroneously warning that you can only input one argument, when in reality you can input up any arbitrary amount.

@JoolCaat , @grif_0 autocomplete should work for ‘x["name"].’ now, can you check if it works for you?

[DevFoyRBX]

Oh yea I been having weird warnings like this all the time, I have no clue how to disable them it’s been happening for me for months

[grif_0 (not_grif)]

Just tested it and it does indeed work. Thanks for the speedy fix.

Last thing, do you by any chance know anything about this?

@grif_0

One thing I have noticed with the module autocomplete is that using a function to require a module based on a name that returns a module doesnt support autocomplete for that module. For example, I have a main function which allows me to require commonly used modules with just the name of it. It returns the module instance, but the autocomplete doesnt show anything for this. Is there something with types I could do or is this a bug with the system?

[OutOfBears (Bear)]

Got some feedback, it seems that double-clicking sometimes will not select the entire word. For example:

[AlaTomKing (Tom)]

Got a problem, tho.

So if you add an if-statement and then add an else to the following, the auto-completion just autocorrects it to ElapsedTime().

Anyway, this is an advantage. So, I don’t need to create a new function just to see what order I have to put the input. I mean, if you create a function and input the first one, the UI just disappears until you skip to the next input. That happened to me.

I have an Intel MBP and I have had an issue like this, it was the colour setting for some reason, have you tried changing it? Apple RGB works well in my experience.

[JoolCaat]

Works, you’re a legend.

I also have an issue with only the new version, where it is auto completing with the wrong symbol, unless remote functions have been changed and I didn’t know. But another thing to note here is it looks like the new version is missing the useful behavior where it would check the context of the script and hide properties accordingly.

(not autocompleting properties that should be indexed with . and not hiding OnClientInvoke which should be hidden)

[gato_todomenso (Kahel)]

we will be able to customize the menu? I think the text it’s way too big and seems hard to read, I would like an option to increase the border size & change the max vertical size of the menu

There is an issue with Callback functions. We have a fix ready, but sadly this one will be delayed for one update after the next one.

This will be cool, we’ll collect and evaluate suggestions from this topic for additional improvements.

[gillern]

When commenting out a line of code that indents the next line, indentation after that will be wrong

[iKaio0991]

Arrow functions in the future ?

[Nootian (Noot)]

I’ve discovered something rather tedious, when typing the word else in, ElapsedTime pops up, and when return is pressed, it replaces else.

Also, ElapsedTime doesn’t include “else” other than removing “ap”(ElsedTime), is that normal?

[caviarbro]

I’ve came across another really annoying “bug”. It always suggest me repeat on first place rather than return and it is slowing my workflow a lot.

[WheretIB]

@sjr04

Will this also work when type casting? That is, if you do (a :: b). , after the period, will autocomplete suggest members of b ?

Yes, if the cast doesn’t have a type error. For example, if ‘a’ is an Instance, ‘(a :: Script).’ will show Script properties.

@sjr04

Also, will event listener parameters be automatically typed?

No, but our team is working on methods to resolve that. Simple cases are simple, but we need to cover some tricky ones with user defined functions if they happen to have overloads or are generic.

@metatablecatmaid

Will developers be able to utilitise with a sort of --!summary comment keyword

Yes, we do have long term plans for that, but it won’t come immediately.

@BenMactavsin

My first question is, are globals that have generic info like these will act like generic functions when generic functions gets re-released?

Yes, they even behave like generic functions in some contexts right now (calling them for example).

@BenMactavsin

And if first answer to that question is a yes, will this trend expand to instance methods like :FindFirstChild ?

We might add generics where appropriate, like for RBXScriptSignal and Instance:Clone.

@Marimariius

Argument types are wonky too ( supposed to show x : number, y : number or something like that )

That function signature should be better now (without magic numbers like 360).

@loueque

Could we get functions in Instance , e.g, childAdded , remove a strikethrough as well, as they’re deprecated, or a heads up (warning)?

childAdded should display as deprecated already.
getChildren and remove aren’t right now, thank you for letting us know, we’ll add this as a bug.

@Weldify

Doesn’t seem to be working with functions placed into dictionaries!

Can you provide a small standalone example?

@LocalWE

Is this intentional behavior?

No.
I can see what the problem is, we are going to address that.

@IAmPinleon

Also, does the autocomplete learn from what you normally type out and have that as the first suggestion?

No.

@EtiTheSpirit

If I try to require this module, I get an error stating the module does not return one value despite this being incorrect

This is a known issue, no ETA on the fix, but we have people working to resolve this.

@paap15

Will you be adding support for getting scripts through WaitForChild, such as when you get scripts from replicated storage on the client

Should be possible, we’ll look into it.

[WheretIB]

We do not plan to add arrow functions.

[redJuli21 (nil)]

So far I’ve been testing out this feature and I like it a lot but I have suggestion, when writing a global like game it will also show it’s deprecated equivalent

It would be better in my opinion to make it show only when you try to write the deprecated equivalent

And autocomplete with the correct one.

[ToldFable (fable)]

This is awesome!

I’ve been reading the Luau wiki, but can’t find a way to have one type inherit stuff from another type. I know pre-baked Roblox types seem to already have this (ex: Part extends BasePart, extends Instance). Is this already a thing? If not, is it planned?

EDIT: Looks like you can use the “&” operator to do this! (see linked post if ur curious)

[Agentotten]

The script editor has always felt lacking so this is a pretty sweet update!
