In Specman, warum ist mein Makro-Label für den Code Körper Rückkehr Müll?

Question

Ähnlich wie bei diesem Beitrag http://feedproxy.google.com/~r/cadence/community/blogs/fv/~3/IvdCIla8_Es/extending-multiple-when-subtypes-simultaneously.aspx

Ich möchte ein Makro machen, die Schleife einige umgehen tut Abrollen der when-Subtypisierung und Erbschaftsangelegenheiten Specman hat.

Ich habe angefangen mit:

-- macros.e
<'
define <FOREACH_UNROLL'action> "FOREACH_UNROLL (<UNROLLEES>\[<unrollee'name>,...\]) (<STATEMENTS>{<statement>;...})" as computed {
   print <UNROLLEES>;
   print str_split(<UNROLLEES>,"/ *, */");
   for each in str_split(<UNROLLEES>,"/ *, */") {
      out(it.as_a(string));
      var statements := str_replace( <STATEMENTS>,"\"REPLACE_ME\"",it);
      result =appendf("%s %s;",result,statements);
   };
};
'>


-- main.e
<'
import macros.e
extend sys {
   run() is also {
      FOREACH_UNROLL [baz,foo,bar] {
         out("REPLACE_ME");
         out("part2","REPLACE_ME");
      };
   };
};
'>

Als ich das laufen, erhalte ich:

specman -c 'load $HOME/main; test'

Wenn Sie beim Ausdruck von <UNROLLEES> aussehen:

<UNROLLEES> = "[35]"

Warum <UNROLLEES> Gib mir [35] anstelle des Körpers innerhalb der geschweiften Klammern? 35 ist der ASCII-Wert für #, so dass ich bei einem Verlust bin, warum ich würde ein 35 bekommen ...

P. S. Ich stelle fest, Makros vom Teufel sind, aber ich denke, Code Kopieren ist noch schlimmer. Ich habe dies zu tun, weil Specman nicht wirklich polymorph ist.

Answer 1

Es stellt sich heraus, ich brauchte die Funktion str_expand_dots in meiner Version von Specman (8.2) zu verwenden.

Hier ist die modifizierte macros.e:

define <FOREACH_UNROLL'action> "FOREACH_UNROLL (<UNROLLEES>\[<unrollee'name>,...\]) (<STATEMENTS>{<statement>;...})" as computed {
   -- print str_expand_dots(<UNROLLEES>);
   --print str_expand_dots(<STATEMENTS>);
   -- print str_split(str_expand_dots(<UNROLLEES>),"/ *, */");
   for each  in str_split(str_expand_dots(<UNROLLEES>),"/ *, */") {
      var unrollee := str_replace(it, "[","");
      unrollee = str_replace(unrollee, "]","");
      --out(unrollee);
      var statements := str_replace( str_expand_dots(<STATEMENTS>),"\"REPLACE_ME\"",unrollee);
      result =appendf("%s %s;",result,statements);
   };
};

Modifizierte main.e:

import macros;
extend sys {
   run() is also {
      FOREACH_UNROLL ["baz","foo","bar"] {
         out("REPLACE_ME");
         out("part2","REPLACE_ME");
         if "REPLACE_ME" == "baz" {
            out("found baz");
         };
      };
   };
};

Und die Ausgabe:
