284 :: accessing a private object field from template

• exhu (orginal) [2013-10-20T15:48:54+02:00] view original

  
  # module A
  TPaulinaContext* = object
          dpy: PDisplay
          rootwin: TWindow
          ......
  
  
  
  
  template step*(c: TPaulinaContext, onWake: stmt): bool =
      bind XNextEvent
      
      bind paulina.TPaulinaContext
      proc templ_step():bool =
          if XNextEvent(c.dpy, addr(c.e)) != 0: # -- here compiler fails to accessc.dpy, c.e
              echo "XNextEvent failed"
              return false
  Run

  
  #module b
  step(c):
      echo("awaken")
  Run

  This code does not compile because of fields of TPaulinaContext are not marked with star and thus not accessible on template instantiation from module B. How can I mark object fields accessible from within template only?

  Currently you can't. You will be able to do this with 0.9.4 once the new symbol binding rules for templates arrive.
