plua_tostring

Declaration

Source position: plua.pas line 18

function plua_tostring(

  L: Plua_State;

  Index: Integer

):ansistring;

Arguments

L

  

PLua_State to work with.

Index

  

Stack index to convert/return.

Function result

AnsiString representing the lua item on the stack at the index provided.

Description

Converts the Lua value at the given acceptable index to a Pascal AnsiString. The Lua value must be a string or a number; otherwise, the function returns NULL. If the value is a number, then plua_tostring also changes the actual value in the stack to a string. (This change confuses lua_next when plua_tostring is applied to keys during a table traversal.)

Example:

function lua_print(l : PLua_State) : integer; cdecl;
var 
  n, c : Integer;
  AString : AnsiString;
begin
  result := 0;
  n := lua_gettop(L);
  AString := '';
  for c := 1 to n do
    AString := AString + plua_tostring(l, c);
  Write(AString);
end;
