-- 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
|
