## Iterator-based directory walks
|
|
|
|
Provides convenient ways to walk directories based on Ada 2012 user-defined
|
|
iterators.
|
|
|
|
Inspired by [walkdir for Rust](https://github.com/BurntSushi/walkdir).
|
|
|
|
|
|
## Walking a directory tree recursively
|
|
|
|
```ada
|
|
with Ada.Directories;
|
|
with Ada.Text_IO;
|
|
with Dir_Iterators.Recursive;
|
|
|
|
-- ...
|
|
|
|
Dir_Walk : constant Dir_Iterators.Recursive.Recursive_Dir_Walk
|
|
:= Dir_Iterators.Recursive.Walk (Dir);
|
|
|
|
for Dir_Entry of Dir_Walk loop
|
|
Ada.Text_IO.Put_Line(Ada.Directories.Full_Name(Dir_Entry));
|
|
end loop;
|
|
```
|
|
|
|
## Walking a directory tree recursively with a filter
|
|
|
|
Use a filter to prune directories and files from the walk.
|
|
|
|
```ada
|
|
with Ada.Directories;
|
|
with Ada.Text_IO;
|
|
with Dir_Iterators.Recursive;
|
|
|
|
package AD renames Ada.Directories;
|
|
|
|
-- ...
|
|
|
|
procedure Foo (Include_Dot_Files : Boolean; Dir_Root : String) is
|
|
function Filter (E : Ada.Directories.Directory_Entry_Type) return Boolean is
|
|
Name : constant String := Ada.Directories.Simple_Name(E);
|
|
begin
|
|
return Include_Dot_Files
|
|
or else (not (Name'Length > 1 and then Name(1) = '.'));
|
|
end Filter;
|
|
|
|
Walk : constant Dir_Iterators.Recursive.Recursive_Dir_Walk :=
|
|
Dir_Iterators.Recursive.Walk (Dir_Root, Filter'Access);
|
|
begin
|
|
for Dir_Entry of Walk loop
|
|
Ada.Text_IO.Put_Line(Ada.Directories.Full_Name(Dir_Entry));
|
|
end loop;
|
|
end Foo;
|
|
```
