6119 :: template - body issue

• mantielero (orginal) [2020-03-25T22:50:58+01:00] view original

  I am trying to do something like the following:

  template tpl(name:string, body:untyped):untyped =
      proc `name Free`()=
          body
  
  tpl("myname"):
      echo "1"
      echo "2"
  
  mynameFree()
  Run

  What am I missing to make it work?

  Secondly, how could I inspect what the template is generating?

  instead of a string use untyped, i.e.

  template tpl(name:untyped, body:untyped):untyped =
      proc `name Free`()=
          body
  
  tpl(myname):
      echo "1"
      echo "2"
  
  mynameFree()
  Run

  One remaning question is how can I see the result from a template execution. I am not talking about invoking the template. For instance in the example above, is there a way to see how:

  tpl(myname):
     echo "1"
     echo "2"
  Run

  gets converted into:

  proc mynameFree() =
     echo "1"
     echo "2"
  Run

  Use expandMacros, like below:

  import macros
  
  template tpl(name: untyped, body: untyped): untyped =
    proc `name Free`()=
      body
  
  expandMacros:
    tpl(myname):
      echo "1"
      echo "2"
  
  mynameFree()
  Run
