Hi,

I would like to announce 1.0.0 release of 
[ThePath](https://code.dlang.org/packages/thepath) library.
It is now stable (there were no big changes to API in last half 
year).



Following ideas used in design of this library:
- Implement struct `Path` that have to represent
   single path to file or directory.
- Avoid implicit modification of created path as much as 
reasonably possible.
   Any operation on path have to create new instance of `Path`,
   instead of modifying original.
- Simplify naming for frequent operations
   (introducing new type for this allows to do it without name 
collisions).
- Automatic tilde (`~`) expansion when needed
   (for example before file operations),
   thus allowing to easily work with path like `~/my/path`,
   that will be resolved implicitly, without any special work 
needed.
- Make this lib as convenient as possible.
- Do not touch other paths (like URL), except filesystem path.
   Easy construction of path from segments and easy conversion of 
path
   to segments (that is array of strings) could help to deal with 
coversion
   to and from other paths (URL).
- It is designed to work with file system paths of OS it is 
compiled for.
   Thus, there is no sense to work with windows-style paths under 
the linux, etc.
- This lib have to be well tested.




  - automatic expansion of `~` when needed (before passing path to 
std.file or std.stdio funcs)
  - single method to copy path (file or directory) to dest path
  - single method to remove path (file or directory)
  - simple method to `walk` through the path
      - `foreach(p; Path.current.walk) writeln(p.toString);`
      - `foreach(p; Path("/tmp").walk) writeln(p.toString);`
  - simple construction of paths from parts:
      - `Path("a", "b", "c")`
      - `Path("a").join("b", "c")`
  - simple deconstruction of paths
      - `Path("a/b/c/d").segments == ["a", "b", "c", "d"]`
      - `Path("a", "b", "c", "d").segments == ["a", "b", "c", "d"]`
  - overriden comparison operators for paths.
      - `Path("a", "b") == Path("a", "b")`
      - `Path("a", "b") != Path("a", "c")`
      - `Path("a", "b") < Path("a", "c")`
  - `hasAttributes` / `getAttributes` / `setAttributes` methods to 
work with file attrs
  - file operations as methods:
      - `Path("my-path").writeFile("Hello world")`
      - `Path("my-path").readFile()`
  - support search by glob-pattern
      - `foreach(path; Path.current.glob("*.py")) 
writeln(p.toString);`
  - easy access to some standard directories via Path's static 
methods:
      - `Path.current` - returns path to current working directory
      - `Path.tempDir` - returns path to default temporary 
directory



```d
import thepath;


Path app_dir = Path("~/.local/my-app");
Path catalog_dir = app_dir.join("catalog");


     void init() {
         // Note, that automatic '~' expansion will be done before 
checking the
         // existense of directory
         if (!app_dir.exists) {
             app_dir.mkdir(true);  // create recursive
         }
         if (!catalog_dir.exists) {
             catalog_dir.mkdir(true);
         }
     }

     void list_dir() {
         // Easily print content of the catalog directory
         foreach(Path p; catalog_dir.walkBreadth) {
             writeln(p.toAbsolute().toString());
         }
     }

     // Print all python files in current directory
     void find_python_files() {
         foreach(path; Path.current.glob("*.py", SpanMode.breadth))
             // Print paths relative to current directory
             writeln(p.relativeTo(Path.current).toString);
     }

     Path findConfig() {
         // Search for "my-project.conf" in current directories 
and in
         // its parent directories
         auto config = 
Path.current.searchFileUp("my-project.conf");
         enforce(!config.isNull);
         return config.get;
     }
```
