Variadic function call with named parameters ? Topic is solved

[Gotjek]

Hi,

I search for this for some time but I can't find the answer.
I read the doc unsuccessfully (https://lexikos.github.io/v2/docs/Functions.htm#VariadicCall).

We can use named parameters when week-end call a function.
It is possible to store these named parameters in a variable, then pass this variable as parameter ?

Here is an example with pseudo-code :

Code: Select all

my_func(day, month, year) {
    MsgBox day " " month " " year
}

my_func(day := 12, month := 04, year := 2022)  ; This works.

params := {%day% : 12, %month% : 04, %year% : 2022}  ; Not sure about the "%"...
my_func(params*)  ; I would like this to work.

You could pass a map instead

Code: Select all

param := Map("day", 12, "month", 04, "year", 2022)

my_func(param)

my_func(params) {
	for key, value in params
		MsgBox key ": " value
}

and you are flexible with the keynames / values

Code: Select all

key1 := "day"
key2 := "month"
key3 := "year"
val1 := 12
val2 := 04
val3 := 2022

param := Map(key1, val1, key2, val2, key3, val3)

/*
param := Map()
param.Set(key1, val1, key2, val2, key3, val3)
*/

my_func(param)

my_func(params) {
	for key, value in params
		MsgBox key ": " value
}

Support was removed, but functionality still remains on v1.

Code: Select all

fn({a: 2, b: 3}*)
fn(a, b) {
   MsgBox % a + b
}

You would have to ask @lexikos if he has any plans to re add named parameters.

Spoiler

Which as you discovered doesn't support

• fn(key:=value)

Code: Select all

fn({a: 2, b: 3}*)
fn(a, b) {
   MsgBox % a + b
}

I was going to check if it respects the order of parameters by changing "a" to "c" but only with that already breaks without getting the answer I wanted .
Edit: I was thinking it worked like arrays. But I rechecked modifying the parameter of the function too and it seems to use what it needs.
But the silent error of v1 was not helpful at all (anyway if it's not supported there's not much to expect).
