SpadParser(): Public == Private where Public ==> with parse: String -> List Syntax ++ parse(f) parses the source file f (supposedly containing ++ Spad algebras) and returns a List Syntax. The filename f ++ is supposed to have the proper extension. Note that this ++ function has the side effect of executing any system command ++ contained in the file f, even if it might not be meaningful. Private ==> add parse f == parseSpadFile(f)$Lisp : List(Syntax)
