I will add 2.1 label since for 2.1 there are planned works on new version of gdscript (or possibly another language with strong typing).

[reduz]

python does this stuff with touples, while gdscript does not support touples. I guess this could be added as syntax sugar though

[reduz]

problem is, python an do something like

a,b=b,a

to swap values, for example, should consider it too

[vnen]

From @Dillybob92 in #4863:

---

I was looking over one of my gdscripts earlier today and thought of this

var client = null
var wrapped_client = null
var GlobalScene
var GamePlayer
var GamePlayer2
var Live_Skills = {}
var GO = {"GAME_VERSION":"1.0.1", "volume":0.15, "CAMERASPEED":7}
var ChatMessages = []
var GameChatMessages = []
var tGameMessages = {}
var user = {"muffin": 1}
var players = {}
var Skills = {}
var Items = {}

Could be:

var client = null, wrapped_client = null,
    GlobalScene, GamePlayer, GamePlayer2,
    Live_Skills = {}, GO = {"GAME_VERSION":"1.0.1", "volume":0.15, "CAMERASPEED":7},
    ChatMessages = [], GameChatMessages = [], tGameMessages = {},
    user = {"muffin": 1}, players = {}, Skills = {},
    Items = {}

I think if 2.1 included this, it would be a nice aesthetic feature. I know it's a personal preference and some devs don't like this, but figured I'd throw this idea out there 🎱

[ghost]

Aww I guess Reduz does know :D So up to him, probably a lot other important stuff for 2.1 ++, but thanks @vnen, didn't see this thread :)

[ghost]

holy shit @vnen s memory is next level

[Barina]

It'll be great to have CSV

[DriNeo]

In Pascal or in Nim language like so:

var
    a = 1
    b = 1.0
    c = "Hello"

It might be a bit nicer to read.

[ghost]

I'd love if we're able to do this

var a,b,c,d=1,2,3,4
a,b,c,d=1,2,3,4
var a,b,c,d={1,2,3,4}

Something like that would be much more useful.

[bojidar-bg]

I want to see a real usecase though, I just think it would make oneliners more prominent :(

[akien-mga]

Well such sugar is not particularly useful.

What is useful, however, is:

var a = 1
var b = 2
var c = 3
var a, b, c = c, a, b
print(a, b, c)  # 3, 1, 2

But that's not trivial to implement.

And of course if the above syntax is supported, then multiple assignment to literals should be supported too, so the above could be:

var a, b, c = 1, 2, 3
var a, b, c = c, a, b
print(a, b, c)  # 3, 1, 2

[ghost]

@akien-mga that's precisely what I had in mind

In fact
var a = 1
var b = 2
var a,b = b, a <<< SUPER SUPER useful
or a,b = b,a
swapping variables is such a common thing in every program

[bojidar-bg]

Ok, let's say I agree that it is useful, even though the implementation would be tricky. 😃

[karroffel]

Oh, the other thread was a duplicate.

Anyway, I could look into how I could implement this with help of the pattern matcher. The lazy approach would just reuse the pattern syntax but that's not very pythonic... I guess I'll play around with it a little bit

[CodeDoes]

@vnev var GlobalScene, GamePlayer, GamePlayer2, Live_Skills = {} would lead to problems.
This might be a better way to write it var GlobalScene = GamePlayer = GamePlayer2 = Live_Skills = {}
Or if your goal was multiple {} then this is more understandable: var GlobalScene, GamePlayer, GamePlayer2, Live_Skills = {}, {}, {}, {}

[vnen]

@ClikCode I was just citing @Dillybob92. And for the sample code, I believe the proposal meant that GlobalScene, GamePlayer and GamePlayer2 would be undefined in the line var GlobalScene, GamePlayer, GamePlayer2, Live_Skills = {}. Only the last one would get a value.

I don't have a personal opinion on this subject.

[CodeDoes]

@vnen To my trained pythonic eyes, that code looked like a syntax error. It's not a problem with you or anyone. I just want the code to be readable.

var {
    X=1
    A=2
    B=3
}

How about this? Reuse the ruby-like dictionary.

[ghost]

@ClikCode a b c = 1 2 3 would be more useful so if you really want it that way maybe
var { a b c } = { 1 2 3 }

[CodeDoes]

@trollworkout that could be done with lists var [a, b, c] = [1, 2, 3] I think keep curly brackets for dictionaries. It could also be done without brackets. var a, b, c = 1, 2, 3

[ghost]

@ClikCode You can even omit the comma. You understand why this is a good idea right?

a =1, b = 2, c = 3
var a b c = 1 2 3

a = 1, b = a, c = b
var a b c = 1 a b

a = 1, b = a, c = (null)
var a b c = 1 a

a = null, b = (null), c = (null)
var a b c = null

create a quick variable swap in a function
a b = b a

Reduces the amount of typing for example only one = equal symbol is necessary and adds the ability to quickly assign one variable value to another.

[ghost]

of course this can be written in so many ways i just find this particular way most useful because no comma only 1 equal and only 1 var

[bojidar-bg]

@trollworkout Let s try writing without any commas periods and other punctuation marks whatsoever ok I find this type of listing items variables topics or just things particularly disgusting myself

Here is the above with the "other punctuation marks" back in:

@trollworkout Let's try writing without any commas, periods, and other punctuation marks whatsoever, ok? I find this type of listing items, variables, topics or just things particularly disgusting myself.

[ghost]

how about we don't even bother about it anymore

[ghost]

if you guys not willing to discuss and just willing to disagree or find things i say "disgusting" let's agree to not even bother about it and not even implement it. sounds like a much better approach. why even debate. i suggest we revert to name calling next.

[akien-mga]

Well Bojidar's word might have been a bit strong, but he was just saying he considers your proposal to chain variable declaration with no separator a bad idea, opinion that I share. There is still interest in having the possibility to declare multiple variable at the same time, but the syntax it should have has to be consensual. Unpacking à la Python with a, b = 1, 2 would be nice, but a syntax like a b = 1 2 is just weird and (AFAIK) unprecedented. If no language in the world uses it, there is likely a good reason, and it's good enough for us not to want to consider it.

Now, thanks for killing this issue that we had taken as reference for other similar requests... I guess I'll just reopen the most relevant one.

[ghost]

@akien-mga Please open another issue have your discussion without me because obviously i'm not needed, wanted or invited. That is my ideas are too "disgusting" for you.

[bojidar-bg]

@trollworkout I'm sorry if you think that I think that your whole proposal is bad (double-read the last sentence, just in case). What I meant is that punctuation marks are there for a reason, and I find it hard to understand others without those. I'm not against a, b = 1, 2 and some of the other ideas expressed above.

Finally, if you find my previous comment too terrible to bear, I would gladly remove it and reapologise for it.

[CodeDoes]

troll is being immature. boji had acted immature as well. but troll, you are trolling. if you over react like that you really need to go see a therapist. we are all trying to get along and work on this amazing project

Ok let's stop trying to make each other's diagnostic, case closed.
