--  Iterators among files
 
package GNAT.Directory_Operations.Iteration is
 
   generic
      with procedure Action
        (Item  :        String;
         Index :        Positive;
         Quit  : in out Boolean);
   procedure Find
     (Root_Directory : Dir_Name_Str;
      File_Pattern   : String);
   --  Recursively searches the directory structure rooted at Root_Directory.
   --  This provides functionality similar to the UNIX 'find' command.
   --  Action will be called for every item matching the regular expression
   --  File_Pattern (see GNAT.Regexp). Item is the full pathname to the file
   --  starting with Root_Directory that has been matched. Index is set to one
   --  for the first call and is incremented by one at each call. The iterator
   --  will pass in the value False on each call to Action. The iterator will
   --  terminate after passing the last matched path to Action or after
   --  returning from a call to Action which sets Quit to True.
   --  Raises GNAT.Regexp.Error_In_Regexp if File_Pattern is ill formed.
 
   generic
      with procedure Action
        (Item  :        String;
         Index :        Positive;
         Quit  : in out Boolean);
   procedure Wildcard_Iterator (Path : Path_Name);
   --  Calls Action for each path matching Path. Path can include wildcards '*'
   --  and '?' and [...]. The rules are:
   --
   --     *       can be replaced by any sequence of characters
   --     ?       can be replaced by a single character
   --     [a-z]   match one character in the range 'a' through 'z'
   --     [abc]   match either character 'a', 'b' or 'c'
   --
   --  Item is the filename that has been matched. Index is set to one for the
   --  first call and is incremented by one at each call. The iterator's
   --  termination can be controlled by setting Quit to True. It is by default
   --  set to False.
   --
   --  For example, if we have the following directory structure:
   --     /boo/
   --        foo.ads
   --     /sed/
   --        foo.ads
   --        file/
   --          foo.ads
   --     /sid/
   --        foo.ads
   --        file/
   --          foo.ads
   --     /life/
   --
   --  A call with expression "/s*/file/*" will call Action for the following
   --  items:
   --     /sed/file/foo.ads
   --     /sid/file/foo.ads
 
end GNAT.Directory_Operations.Iteration;
