4559 :: Is it possible get the export flag of a type symbol

• slangmgh (orginal) [2019-01-16T01:14:29+01:00] view original

  I am writing a macro which need to know if a type symbol is exported or not. But the getImpl doesn't contain export flag. The following code:

  
  import macros
  type
     T1* = object
  
  macro m1(t: typed): untyped =
     echo t.getImpl.treeRepr
  
  m1(T1)
  Run

  The result is:

  
  TypeDef
    Sym "T1"
    Empty
    ObjectTy
      Empty
      Empty
      Empty
  Run

  Is there any way to get the export flag or other way to check if the symbol is exported or not? Thanks.

  You can use when compiles(TYPE SYMBOL):.

  The macro will executed in scope which define the type symbol, so the when compiles will be always true.

  You can check for the export marker in the AST if you instead accept an untyped parameter. There is no macros.isExportedSymbol. PRs are welcome.
