General ⇒ comment partial in source with lstinputlisting

[qianjigui]

Thanks for seeing this post.

I use \lstinputlisting to input some vhdl codes, but I only want some code display in the document. So I try to use \begin{comment} \end{comment}, but I failed.

Maybe there are some ways to solve this question.
\lstinputlisting[first=..., last=...] may be not a good solution.

Code: Select all

-- VHDL source assignment

library ieee;
use ieee.std_logic_1164.all;
use std.textio.all;
use work.text_util.all;

entity assignment is
  --port(a,b:in integer);
end;

-- architecture example
architecture one of assignment is
  signal a,b:integer;
begin
  assign_var:process
    variable a,b:integer;
  begin
    -- (*@ \begin{comment}
    print(output,"var");
    print(output,"var-a:");
    print(output,str(a));
    print(output,"var-b:");
    print(output,str(b));
    print(output,"first assignment");
    --\end{comment} @*)
    a := 4;
    b := 5;

    -- (*@ \begin{comment}
    print(output,"var-a:");
    print(output,str(a));
    print(output,"var-b:");
    print(output,str(b));
    print(output,"assignment");
    --\end{comment} @*)
    a := b;
    b := a;


    -- (*@ \begin{comment}

    print(output,str(a));
    print(output,"var-b:");
