Re: Create type with macro that depends on other types in a type block

[enthus1ast]

Got it! :)

at first i dumped the ast:
    
    
    World {.dumpAstGen.} = ref object
        guids: GUID
        storeHealthAble: Store[CompHealthAble]
        storeDrawAble: Store[CompDrawAble]
        storeNameAble: Store[CompNameAble]
    
    
    Run

this works because the ast that generates this type is passed to the 
dumpAstGen. Then i copied the ast into a new macro and added my generation 
code. The only thing was that i had to put Components into its own type 
section.:
    
    
    type
      Component = enum
        DrawAble, HealthAble, NameAble, FOOAble
    
    
    macro genWorld(left: typed, componentEnum: untyped) =
      
      var typeTree = newNimNode(nnkRecList)
      typeTree.add nnkIdentDefs.newTree(
          newIdentNode("guids"),
          newIdentNode("GUID"),
          newEmptyNode()
        )
      for component in Component:
        typeTree.add nnkIdentDefs.newTree(
          newIdentNode("store" & $component ),
          nnkBracketExpr.newTree(
            newIdentNode("Store"),
            newIdentNode("Comp" & $component)
          ),
          newEmptyNode()
        )
      
      return nnkTypeDef.newTree(
        nnkPragmaExpr.newTree(
          newIdentNode("World"),
          nnkPragma.newTree(
          )
        ),
        newEmptyNode(),
        nnkRefTy.newTree(
          nnkObjectTy.newTree(
            newEmptyNode(),
            newEmptyNode(),
            typeTree
          )
        )
      )
    
    # another type section
    type
        World {.genWorld: Component.}
    
    
    Run
