32
--  This package is intended to be used in conjunction with its parent unit,
33
--  Ada.Command_Line. It provides facilities for logically removing arguments
34
--  from the command line, so that subsequent calls to Argument_Count and
35
--  Argument will reflect the removals.
36
 
37
--  For example, if the original command line has three arguments A B C, so
38
--  that Argument_Count is initially three, then after removing B, the second
39
--  argument, Argument_Count will be 2, and Argument (2) will return C.

package Ada.Command_Line.Remove is
42

43
 
44
   procedure Remove_Argument (Number : Positive);
45
   --  Removes the argument identified by Number, which must be in the
46
   --  range 1 .. Argument_Count (i.e. an in range argument number which
47
   --  reflects removals). If Number is out of range Constraint_Error
48
   --  will be raised.
49
   --
50
   --  Note: the numbering of arguments greater than Number is affected
51
   --  by the call. If you need a loop through the arguments, removing
52
   --  some as you go, run the loop in reverse to avoid confusion from
53
   --  this renumbering:
54
   --
55
   --    for J in reverse 1 .. Argument_Count loop
56
   --      if Should_Remove (Arguments (J)) then
57
   --        Remove_Argument (J);
58
   --      end if;
59
   --    end loop;
60
   --
61
   --  Reversing the loop in this manner avoids the confusion.

64
   --  Removes arguments in the given From..To range. From must be in the
65
   --  range 1 .. Argument_Count and To in the range 0 .. Argument_Count.
66
   --  Constraint_Error is raised if either argument is out of range. If
67
   --  To is less than From, then the call has no effect.

   procedure Remove_Argument (Argument : String);
70
   --  Removes the argument which matches the given string Argument. Has
71
   --  no effect if no argument matches the string. If more than one
72
   --  argument matches the string, all are removed.
73
 
74
   procedure Remove_Arguments (Argument_Prefix : String);
75
   --  Removes all arguments whose prefix matches Argument_Prefix. Has
76
   --  no effect if no argument matches the string. For example a call
77
   --  to Remove_Arguments ("--") removes all arguments starting with --.
