+**Note** `ls()` does not throw, instead outputing a warning to the console if it

+
+We provide `find()` for recursive listing:

+Some parts of `FileManager` are not exactly idiomatic. For example
+`isExecutableFile` returns `true` even if there is no file there, it is instead
+telling you that *if* you made a file there it *could* be executable. Thus we
+check the POSIX permissions of the file first, before returning the result of
+`isExecutableFile`. `Path.swift` has done the leg-work for you so you can just
+get on with it and not have to worry.
+
+There is also some magic going on in Foundation’s filesystem APIs, which we look
+for and ensure our API is deterministic, eg. [this test].

+                              // thus use `realpath` if there are multiple symlinks
 ```

+*Path.swift* has the general policy that if the desired end result preexists,
+then it’s a noop:
+
+* If you try to delete a file, but the file doesn't exist, we do nothing.
+* If you try to make a directory and it already exists, we do nothing.
+* If you call `readlink` on a non-symlink, we return `self`
+
+However notably if you try to copy or move a file without specifying `overwrite`
+and the file already exists at the destination and is identical, we don’t check
+for that as the check was deemed too expensive to be worthwhile.
+
+## Symbolic links
+
+* Two paths may represent the same *resolved* path yet not be equal due to
+    symlinks in such cases you should use `realpath` on both first if an
+    equality check is required.
+* There are several symlink paths on Mac that are typically automatically
+    resolved by Foundation, eg. `/private`, we attempt to do the same for
+    functions that you would expect it (notably `realpath`), we *do* the same
+    for `Path.init`, but *do not* if you are joining a path that ends up being
+    one of these paths, (eg. `Path.root.join("var/private')`).
+
+If a `Path` is a symlink but the destination of the link does not exist `exists`
+returns `false`. This seems to be the correct thing to do since symlinks are
+meant to be an abstraction for filesystems. To instead verify that there is
+no filesystem entry there at all check if `type` is `nil`.
+
+
+## We do not provide change directory functionality
+
+Changing directory is dangerous, you should *always* try to avoid it and thus
+we don’t even provide the method. If you are executing a sub-process then
+use `Process.currentDirectoryURL`.
+
+If you must then use `FileManager.changeCurrentDirectory`.
+
+# I thought I should only use `URL`s?
+
+Apple recommend this because they provide a magic translation for
+[file-references embodied by URLs][file-refs], which gives you URLs like so:
+
+    file:///.file/id=6571367.15106761
+
+Therefore, if you are not using this feature you are fine. If you have URLs the
+correct way to get a `Path` is:
+
+```swift
+if let path = Path(url: url) {
+    /*…*/
+}
+```
+
+Our initializer calls `path` on the URL which resolves any reference to an
+actual filesystem path, however we also check the URL has a `file` scheme first.
+
+[file-refs]: https://developer.apple.com/documentation/foundation/nsurl/1408631-filereferenceurl

+# In defense of our naming scheme

+Chainable syntax demands short method names, thus we adopted the naming scheme
+of the terminal, which is absolutely not very “Apple” when it comes to how they
+design their APIs, however for users of the terminal (which *surely* is most
+developers) it is snappy and familiar.
+
 # Installation

 SwiftPM:

 ```swift
-package.append(.package(url: "https://github.com/mxcl/Path.swift", from: "0.4.1"))
+package.append(.package(url: "https://github.com/mxcl/Path.swift.git", from: "1.0.0"))
 ```

 CocoaPods:

 ```ruby
-pod 'Path.swift' ~> '0.4.1'
+pod 'Path.swift', '~> 1.0.0'
 ```

-Please note! We are pre 1.0, thus we can change the API as we like! We will tag
-1.0 as soon as possible.

 /**
- Represents a platform filesystem absolute path.
+ A `Path` represents an absolute path on a filesystem.

- The recommended conversions from string are:
+ All functions on `Path` are chainable and short to facilitate doing sequences
+ of file operations in a concise manner.
+
+ `Path` supports `Codable`, and can be configured to
+ [encode paths *relatively*](https://github.com/mxcl/Path.swift/#codable).
+
+ Sorting a `Sequence` of paths will return the locale-aware sort order, which
+ will give you the same order as Finder.
+
+ Converting from a `String` is a common first step, here are the recommended
+ ways to do that:

     let p1 = Path.root/pathString
     let p2 = Path.root/url.path
     let p3 = Path.cwd/relativePathString
     let p4 = Path(userInput) ?? Path.cwd/userInput

- - Note: There may not be an actual filename at the path.
+ If you are constructing paths from static-strings we provide support for
+ dynamic members:
+
+     let p1 = Path.root.usr.bin.ls  // => /usr/bin/ls
+
+ However we only provide this support off of the static members like `root` due
+ to the anti-pattern where Path.swift suddenly feels like Javascript otherwise.
+
+ - Note: A `Path` does not necessarily represent an actual filesystem entry.
+ - SeeAlso: `Pathish` for most methods you will use on `Path` instances.

Max Howell	0e061f9cc8	Adds `kind` fixes deleting broken symlinks `delete()` and other functions would check `exists` to do certain behaviors, but `exists` will validate a symlink if the entry is a symlink, thus instead we check if the path is an actual entry now instead.	2019-03-18 19:47:49 -04:00

Max Howell	83c83dcaba	Bundle extensions don’t return optional Paths Rationale: Paths are not guaranteed to exist, the Bundle functions return optional if the path doesn't exist. So we'll provide a sensible default instead and you need to check the result exists at some point instead. This makes more elegant chains, the chain will fail when you operate on it, but you don’t have to do a check for optional first. Or risk a bang.	2019-01-26 15:20:32 -05:00
