Hey guys, how can I call a function extension that is declared in another class?

[kirillrakhman]

jackmiras: the best way is to just make the function top-level

How can I do a top level function?

[kirillrakhman]

just put it outside the class

[jackmiras]

I've done this but I'm having some problems in call the function.

[jackmiras]

Even if I specify the package of the class that holds the extended function the IDE doesn't find the function.

@jackmiras post some code

[jackmiras]

I have this class that has a extension function:

class RequestExtentions {

    fun Request.bodyObject(): Any {
        try {
            return Parser().toKotlin(body())
        } catch (e: Exception) {
            return e
        }
    }

}

[jackmiras]

I would like to call the function above in another class just like the code down below:

override fun post(req: Request, res: Response): Any {
        val platform = req.bodyObject()
    }

[jackmiras]

The problem is that when I try to do this val platform = req.bodyObject() I can't import the bodyObject function

[Andreas Sinz]

i'm not sure this is possible. why not put the extension method outside of the class?

[Andreas Sinz]

or put the extension method next to your fun post(..)

[jackmiras]

The extension function was next to the fun post(...) but this function will repeat along other classes.

[jackmiras]

That's why I would like to move the function to the class RequestExtentions {...}

[jackmiras]

@Andreas Sinz do you know if there is a way to make this work?

[Andreas Sinz]

@jackmiras nope, I don't know any way to do it. just make your extension function a top-level function

[jackmiras]

@Andreas Sinz the top-level function actually work, thanks a lot!!
