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;
