8523 :: New wrapping strategy for "c define" ?

• marc (orginal) [2021-10-21T09:23:44+02:00] view original

  Hi guys,

  till nim-1.4.8 I can "wrao a c #define" like in the expample below without problems:

  {.emit: """ #define SQR(x) ((x)*(x)) """.} proc SQR(x: int32): int32 {.importc, noDecl.} echo ("Number: " & {SQR(10)}).fmt

  Since nim-1.6.0 I get the following error now: Error: type mismatch: got <string, set[range 0..65535(int)]>

  Please can someone explain me, what is the new wrapping strategy now for constructs like these?

  Cheers, Marc

  There error is from "Number: " & {SQR10}.

  I think you meant to write fmt"Number: {SQR(10)}"

  Thanks for your hint, ynfle!

  Curious enough that the former syntax also worked before 1.6.0 ...

  I doubt it worked in earlier versions.

  Which version did it work with? You can try any version on choosenim
