nimforum mirror - Can't nest VNode inside other VNode

andrealicheri (orginal) [2023-03-29T20:50:02+02:00] view original

I have this code:


include karax/prelude
import components/main

proc test(): Vnode =
    text("helo")

proc router(data: RouterData): VNode =
    buildHtml(tdiv):
        if data.hashPart == "#/":
            test

setRenderer(router)

but I get this error:


 Error: type mismatch: got <proc (): VNode{.noSideEffect, gcsafe, locks: 0.}>
but expected one of:
proc add(parent, kid: VNode)
  first type mismatch at position: 1

  but expression 'test' is of type: proc (): VNode{.noSideEffect, gcsafe, locks: 0.}

  but expression 'test' is of type: proc (): VNode{.noSideEffect, gcsafe, locks: 0.}

expression: add(test)

Any help?
