is there a way to make use of an infix modifier in a "postfix" kinda way, in othe words being allowed to exclude the trailing param?
This is what i'm trying to do, but i'm forced to trail the DSL with a garbage value, in this case Unit

infix fun postgresql.DESC(value: Unit): postgresql {
			return this
		}

	}


	fun main() {

		postgresql {
			SELECT (
				ListingTable::section, ListingTable::id,
				ListingImageTable::name, ListingImageTable::listingId
			) FROM (
				ListingTable::class
			) LEFT JOIN (
				ListingImageTable::class
			) ON (
				ListingTable::id == ListingImageTable::id
			) WHERE (
				true
			) ORDER BY(ListingTable::modified) DESC Unit


		}

what if the value param had a default value?

[janvladimirmostert]

'infix' modifier is inapplicable on this function: should not have varargs or parameters with default values

[janvladimirmostert]

interesting idea though

[Big Chungus]

Try value: Never

[janvladimirmostert]

I've tried Nothing, after DESC, it still says Expecting an element

[Big Chungus]

Hold on, shouldn't infix functions have a receiver?

[janvladimirmostert]

yes, each of those SELECT, FROM, LEFT, JOIN, ON, WHERE are functions that return the type Postgresql

[Big Chungus]

No, I'm saying your DESC function declaration doesn't have a receiver

[janvladimirmostert]

explain ?

[Big Chungus]

First line of your snippet

[Big Chungus]

Shouldn't it be infix fun postgresql.DESC(...)...

[janvladimirmostert]

not quite following what is meant by a receiver, i've heard the terminology being used, but not sure what it means

[Big Chungus]

Receiver is postgresql in my example above

[Big Chungus]

It's the "this" of the function

[janvladimirmostert]

ah
although that makes no difference

infix fun postgresql.DESC(value: Nothing): postgresql {
			return this
		}

[janvladimirmostert]

i was trying to see if i can make it a regular function call, maybe even DESC() as a last resort

[nanodeath]

you could make DESC a parameter of BY instead

[janvladimirmostert]

yeah, that's a possibility, then make DESC / ASC enums. Will need to see what other edge cases there are that requires an end-of-line type of infix function

let me post this in language proposals, infix functions with default values making the input optional
