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

|
|
|
|
procedure Remove_Argument (Number : Positive);
|
|
-- Removes the argument identified by Number, which must be in the
|
|
-- range 1 .. Argument_Count (i.e. an in range argument number which
|
|
-- reflects removals). If Number is out of range Constraint_Error
|
|
-- will be raised.
|
|
--
|
|
-- Note: the numbering of arguments greater than Number is affected
|
|
-- by the call. If you need a loop through the arguments, removing
|
|
-- some as you go, run the loop in reverse to avoid confusion from
|
|
-- this renumbering:
|
|
--
|
|
-- for J in reverse 1 .. Argument_Count loop
|
|
-- if Should_Remove (Arguments (J)) then
|
|
-- Remove_Argument (J);
|
|
-- end if;
|
|
-- end loop;
|
|
--
|
|
-- Reversing the loop in this manner avoids the confusion.

|

|
procedure Remove_Arguments (From : Positive; To : Natural);
|
|
-- Removes arguments in the given From..To range. From must be in the
|
|
-- range 1 .. Argument_Count and To in the range 0 .. Argument_Count.
|
|
-- Constraint_Error is raised if either argument is out of range. If
|
|
-- To is less than From, then the call has no effect.
|
|
|
|
procedure Remove_Argument (Argument : String);
|
|
-- Removes the argument which matches the given string Argument. Has
|
|
-- no effect if no argument matches the string. If more than one
|
|
-- argument matches the string, all are removed.
|
|
|
|
procedure Remove_Arguments (Argument_Prefix : String);
|
|
-- Removes all arguments whose prefix matches Argument_Prefix. Has
|
|
-- no effect if no argument matches the string. For example a call
|
|
-- to Remove_Arguments ("--") removes all arguments starting with --.
