-Support for well-typed paths in Haskell. Also provides ByteString based filepath
-manipulation.
+Set of libraries to deal with filepaths and files.
 
 ## Motivation
 
-The motivation came during development of
-[hsfm](https://github.com/hasufell/hsfm)
-which has a pretty strict File type, but lacks a strict Path type, e.g.
-for user input.
+* filepaths should be type-safe (absolute, relative, ...)
+* filepaths should be ByteString under the hood, see [Abstract FilePath Proposal (AFPP)](https://gitlab.haskell.org/ghc/ghc/wikis/proposal/abstract-file-path)
+* file high-level operations should be platform-specific, exception-stable, safe and as atomic as possible
 
-The library that came closest to my needs was
-[path](https://github.com/chrisdone/path),
-but the API turned out to be oddly complicated for my use case, so I
-decided to fork it.
-
-Similarly, [posix-paths](https://github.com/JohnLato/posix-paths)
-was exactly what I wanted for the low-level operations, but upstream seems dead,
-so it is forked as well and merged into this library.
-
-## Goals
-
-* well-typed paths
-* high-level API to file operations like recursive directory copy
-* safe filepath manipulation, never using String as filepath, but ByteString
-* still allowing sufficient control to interact with the underlying low-level calls
-
-Note: this library was written for __posix__ systems and it will probably not support other systems.
-
-## Differences to 'path'
-
-* doesn't attempt to fake IO-related information into the path, so whether a path points to a file or directory is up to your IO-code to decide...
-* trailing path separators will be preserved if they exist, no messing with that
-* uses safe ByteString for filepaths under the hood instead of unsafe String
-* fixes broken [dirname](https://github.com/chrisdone/path/issues/18)
-* renames dirname/filename to basename/dirname to match the POSIX shell functions
-* introduces a new `Path Fn` for safe filename guarantees and a `RelC` class
-* allows pattern matching via unidirectional PatternSynonym
-* uses simple doctest for testing
-* allows `~/` as relative path, because on posix level `~` is just a regular filename that does _NOT_ point to `$HOME`
-* remove TH, it sucks
-
-## Differences to 'posix-paths'
-
-* uses the `word8` package for save word8 literals instead of `OverloadedStrings`
-* `hasTrailingPathSeparator` and `dropTrailingPathSeparator` behave in the same way as their `System.FilePath` counterpart
-* added various functions:
-    * `equalFilePath`
-    * `getSearchPath`
-    * `hasParentDir`
-    * `hiddenFile`
-    * `isFileName`
-    * `isValid`
-    * `makeRelative`
-    * `makeValid`
-    * `normalise`
-    * `splitSearchPath`
-    * `stripExtension`
-* has a custom versions of `openFd` which allows more control over the flags than its unix package counterpart
-* adds a `getDirectoryContents'` version that works on Fd
-
-## Examples in ghci
-
-Start ghci via `cabal repl`:
-
-```hs
--- enable OverloadedStrings
-:set -XOverloadedStrings
--- import HPath.IO
-import HPath.IO
--- parse an absolute path
-abspath <- parseAbs "/home"
--- parse a relative path (e.g. user users home directory)
-relpath <- parseRel "jule"
--- concatenate paths
-let newpath = abspath </> relpath
--- get file type
-getFileType newpath
--- return all contents of that directory
-getDirsFiles newpath
--- return all contents of the parent directory
-getDirsFiles (dirname newpath)
-```

+
+Support for bytestring based filepath manipulation, similar to 'filepath'.
+
+This package is part of the HPath suite, also check out:
+
+* [hpath](https://hackage.haskell.org/package/hpath)
+* [hpath-directory](https://hackage.haskell.org/package/hpath-directory)
+* [hpath-io](https://hackage.haskell.org/package/hpath-io)
+
+## Motivation
+
+This is basically a fork of [posix-paths](https://github.com/JohnLato/posix-paths), which seemed to have stalled development.
+
+There is also a similar library [filepath-bytestring](https://hackage.haskell.org/package/filepath-bytestring), but it doesn't follow an open development model and is cross-platform, which this library is not interested in.
+
+## Differences to 'posix-paths'
+
+* uses the `word8` package for save word8 literals instead of `OverloadedStrings`
+* `hasTrailingPathSeparator` and `dropTrailingPathSeparator` behave in the same way as their `System.FilePath` counterpart
+* has some additional functions
+
+## Differences to 'filepath-bytestring'
+
+* uses the `word8` package for save word8 literals instead of `OverloadedStrings`
+* is not cross-platform (less odd code to maintain)
+* has some additional functions

+# Revision history for hpath-io
+
+## 0.13.2 -- 2020-05-08
+
+* Add getDirsFilesStream and use streamly-posix for dircontents (#34)
+
+## 0.13.0 -- 2020-01-26
+
+* switch to using 'hpath-bytestring' for the implementation (this is now just a wrapper module, mostly)
+
+## 0.12.0 -- 2020-01-20
+
+* breaking API changes
+	* RelC and Fn were removed from `hpath`
+	* further changes to `parseAny`
+
+
+## 0.11.0 -- 2020-01-18
+
+* `writeFile` not allows to set file mode and create file if it does not exist (this broke API)
+* added various new functions:
+	* createDirIfMissing
+	* writeFileL (for lazy bytestring)
+	* isReadable
+	* isExecutable
+	* getModificationTime
+	* setModificationTime
+	* setModificationTimeHiRes
+	* getDirsFiles' (returns filenames instead of paths)
+	* withRawFilePath
+	* withHandle
+
+## 0.10.1 -- 2020-01-13
+
+* Move file check functions to HPath.IO
+* Add 'doesExist'
+* Exception handling of `doesExist`, `doesFileExist`, `doesDirectoryExist` has changed: only eNOENT is catched
+* Exception handling of `isWritable` has changed: just a wrapper around `access` now
+* switch exception handling to `safe-exceptions`
+* Redo file reading API (readFileEOF dropped and now using streamly under the hood, added `readFileStream`)
+
+
+## 0.10.0 -- 2020-01-04
+
+* First version. Split from 'hpath', contains only the IO parts.
+* Now uses streamly for 'copyFile'
+* Fixed tmpdir in hspec

+
+High-level IO operations on files/directories, utilizing type-safe Paths. This uses [hpath-directory](https://hackage.haskell.org/package/hpath-directory) under the hood.
+
+This package is part of the HPath suite, also check out:
+
+* [hpath](https://hackage.haskell.org/package/hpath)
+* [hpath-directory](https://hackage.haskell.org/package/hpath-directory)
+* [hpath-filepath](https://hackage.haskell.org/package/hpath-filepath)
+
+## Motivation
+
+The motivation came during development of
+[hsfm](https://github.com/hasufell/hsfm)
+in order to have a proper high-level API of file related operations,
+while utilizing type-safe Paths.
+
+## Goals
+
+* high-level API to file operations like recursive directory copy
+* still allowing sufficient control to interact with the underlying low-level calls
+* unit-testing exceptions (because yes, people may rely on them)
+
+Note: this library was written for __posix__ systems and it will probably not support other systems.

+-- Stability   :  experimental

+--
+-- This module provides high-level IO related file operations like
+-- copy, delete, move and so on. It only operates on /Path x/ which
+-- guarantees us well-typed paths. This is a thin wrapper over
+-- System.Posix.RawFilePath.Directory in 'hpath-directory'. It's
+-- encouraged to use this module.
+--
+-- Some of these operations are due to their nature __not atomic__, which
+-- means they may do multiple syscalls which form one context. Some
+-- of them also have to examine the filetypes explicitly before the
+-- syscalls, so a reasonable decision can be made. That means
+-- the result is undefined if another process changes that context
+-- while the non-atomic operation is still happening. However, where
+-- possible, as few syscalls as possible are used and the underlying
+-- exception handling is kept.
+--
+-- Note: `BlockDevice`, `CharacterDevice`, `NamedPipe` and `Socket`
+-- are ignored by some of the more high-level functions (like `easyCopy`).
+-- For other functions (like `copyFile`), the behavior on these file types is
+-- unreliable/unsafe. Check the documentation of those functions for details.

+--
+-- For directory contents, this will ignore any file type that is not

hpath/CHANGELOG

@@ -1,3 +1,27 @@
+0.11.0
+	* Many API breaking changes
+	* Remove RelC and Fn, because they complicate API/break semantics (see #29)
+	* Redo 'parseAny'
+	* Unexpose HPath.Internal
+	* Don't preserve trailing path separators (if you need to pass something to a C function that way, do it manually)
+	* Added `rooPath`, `isRootPath`, `getAllComponents`, `getAllComponentsAfterRoot`
+0.10.2
+	* Add `parseAny` and the related QuasiQuoter
+0.10.1
+	* Add quasi quoters for hpath
+0.10.0
+	* split packages, this one now just contains the type-safe Path wrappers
+0.9.2
+	* fix build with ghc-7.6
+	* raise required bytestring version
+	* Tighten base bound to prevent building before GHC 7.6 (by George Wilson)
+0.9.1
+	* fix build with ghc-7.8 and 7.10
+0.9.0
+	* don't force "Path Abs" anymore in IO module, abstract more over Path types
+	* add 'toAbs'
+0.8.1
+	* add 'readFile', 'readFileEOF', 'writeFile' and 'appendFile'
 0.8.0
 	* 'copyDirRecursiveOverwrite', 'copyFileOverwrite', 'easyCopyOverwrite' and 'moveFileOverwrite' have been removed, instead use the versions without the *Overwrite suffix and pass in 'Strict' (for default behavior) or 'Overwrite' as the CopyMode argument
 	* introduced a new 'RecursiveErrorMode' type to allow controlling recursive behavior of 'copyDirRecursive' (use 'FailEarly' for default behavior)

+
+Support for well-typed paths in Haskell.
+
+This package is part of the HPath suite, also check out:
+
+* [hpath-directory](https://hackage.haskell.org/package/hpath-directory)
+* [hpath-filepath](https://hackage.haskell.org/package/hpath-filepath)
+* [hpath-io](https://hackage.haskell.org/package/hpath-io)
+
+## Motivation
+
+The motivation came during development of
+[hsfm](https://github.com/hasufell/hsfm)
+which has a pretty strict File type, but lacks a strict Path type, e.g.
+for user input.
+
+The library that came closest to my needs was
+[path](https://github.com/chrisdone/path),
+but the API turned out to be oddly complicated for my use case, so I
+decided to fork it.
+
+## Goals
+
+* well-typed paths
+* safe filepath manipulation, never using String as filepath, but ByteString
+
+Note: this library was written for __posix__ systems and it will probably not support other systems.
+
+## Differences to 'path'
+
+* doesn't attempt to fake IO-related information into the path, so whether a path points to a file or directory is up to your IO-code to decide...
+* uses safe ByteString for filepaths under the hood instead of unsafe String
+* fixes broken [dirname](https://github.com/chrisdone/path/issues/18)
+* renames dirname/filename to basename/dirname to match the POSIX shell functions
+* allows pattern matching via unidirectional PatternSynonym
+* uses simple doctest for testing
+* allows `~/` as relative path, because on posix level `~` is just a regular filename that does _NOT_ point to `$HOME`

--- Copyright   :  © 2016 Julian Ospald

--- Maintainer  :  Julian Ospald <hasufell@posteo.de>
--- Stability   :  experimental
--- Portability :  portable
---
--- This module provides high-level IO related file operations like
--- copy, delete, move and so on. It only operates on /Path Abs/ which
--- guarantees us well-typed paths which are absolute.
---
--- Some functions are just path-safe wrappers around
--- unix functions, others have stricter exception handling
--- and some implement functionality that doesn't have a unix
--- counterpart (like `copyDirRecursive`).
---
--- Some of these operations are due to their nature __not atomic__, which
--- means they may do multiple syscalls which form one context. Some
--- of them also have to examine the filetypes explicitly before the
--- syscalls, so a reasonable decision can be made. That means
--- the result is undefined if another process changes that context
--- while the non-atomic operation is still happening. However, where
--- possible, as few syscalls as possible are used and the underlying
--- exception handling is kept.
---
--- Note: `BlockDevice`, `CharacterDevice`, `NamedPipe` and `Socket`
--- are ignored by some of the more high-level functions (like `easyCopy`).
--- For other functions (like `copyFile`), the behavior on these file types is
--- unreliable/unsafe. Check the documentation of those functions for details.

--- the following, without descending into the destination if it

---
--- @
---   cp -a \/source\/dir \/destination\/somedir
--- @
---
--- For directory contents, this will ignore any file type that is not

---
--- For `Overwrite` copy mode this does not prune destination directory

--- Safety/reliability concerns:
---
---    * not atomic

---    * an explicit check `throwDestinationInSource` is carried out for the
---      top directory for basic sanity, because otherwise we might end up
---      with an infinite copy loop... however, this operation is not
---      carried out recursively (because it's slow)

---    - `NoSuchThing` if source directory does not exist
---    - `PermissionDenied` if source directory can't be opened
---    - `SameFile` if source and destination are the same file
