## Motivation
|
||||
|
||||
* 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
|
||||
It was after working on a number of projects at FP Complete that use file
|
||||
paths in various ways. We used the system-filepath package, which was
|
||||
supposed to solve many path problems by being an opaque path type. It
|
||||
occurred to me that the same kind of bugs kept cropping up:
|
||||
|
||||
## Projects
|
||||
* Expected a path to be absolute but it was relative, or vice-versa.
|
||||
|
||||
* [![Hackage version](https://img.shields.io/hackage/v/hpath.svg?label=Hackage)](https://hackage.haskell.org/package/hpath) [hpath](./hpath): Support for well-typed paths
|
||||
* [![Hackage version](https://img.shields.io/hackage/v/hpath-filepath.svg?label=Hackage)](https://hackage.haskell.org/package/hpath-filepath) [hpath-filepath](./hpath-filepath): ByteString based filepath manipulation (can be used without hpath)
|
||||
* [![Hackage version](https://img.shields.io/hackage/v/hpath-directory.svg?label=Hackage)](https://hackage.haskell.org/package/hpath-directory) [hpath-directory](./hpath-directory): High-level IO operations for files/directories on raw ByteString filepaths (use hpath-io for the type-safe path version)
|
||||
* [![Hackage version](https://img.shields.io/hackage/v/hpath-io.svg?label=Hackage)](https://hackage.haskell.org/package/hpath-io) [hpath-io](./hpath-io): High-level IO operations for files/directories utilizing type-safe Path
|
||||
* [![Hackage version](https://img.shields.io/hackage/v/hpath-posix.svg?label=Hackage)](https://hackage.haskell.org/package/hpath-posix) [hpath-posix](./hpath-posix): Some low-level POSIX glue code that is not in 'unix'
|
||||
* Expected two equivalent paths to be equal or order the same, but they did
|
||||
not (`/home//foo` vs `/home/foo/` vs `/home/bar/../foo`, etc.).
|
||||
|
||||
* Unpredictable behaviour with regards to concatenating paths.
|
||||
|
||||
* Confusing files and directories.
|
||||
|
||||
* Not knowing whether a path was a file or directory or relative or absolute
|
||||
based on the type alone was a drag.
|
||||
|
||||
All of these bugs are preventable.
|
||||
|
||||
## Approach
|
||||
|
||||
My approach to problems like this is to make a type that encodes the
|
||||
properties I want and then make it impossible to let those invariants be
|
||||
broken, without compromise or backdoors to let the wrong value “slip
|
||||
in”. Once I have a path, I want to be able to trust it fully. This theme
|
||||
will be seen throughout the things I lay out below.
|
||||
|
||||
## Solution
|
||||
|
||||
After having to fix bugs due to these in our software, I put my foot down
|
||||
and made:
|
||||
|
||||
* An opaque `Path` type (a newtype wrapper around `String`).
|
||||
|
||||
* Smart constructors which are very stringent in the parsing.
|
||||
|
||||
* Make the parsers highly normalizing.
|
||||
|
||||
* Leave equality and concatenation to basic string equality and
|
||||
concatenation.
|
||||
|
||||
* Include relativity (absolute/relative) and type (directory/file) in the
|
||||
type itself.
|
||||
|
||||
* Use the already cross-platform
|
||||
[filepath](http://hackage.haskell.org/package/filepath) package for
|
||||
implementation details.
|
||||
|
||||
## Implementation
|
||||
|
||||
### The data types
|
||||
|
||||
Here is the type:
|
||||
|
||||
```haskell
|
||||
newtype Path b t = Path FilePath
|
||||
deriving (Typeable)
|
||||
```
|
||||
|
||||
The type variables are:
|
||||
|
||||
* `b` — base, the base location of the path; absolute or relative.
|
||||
* `t` — type, whether file or directory.
|
||||
|
||||
The base types can be filled with these:
|
||||
|
||||
```haskell
|
||||
data Abs deriving (Typeable)
|
||||
data Rel deriving (Typeable)
|
||||
```
|
||||
|
||||
And the type can be filled with these:
|
||||
|
||||
```haskell
|
||||
data File deriving (Typeable)
|
||||
data Dir deriving (Typeable)
|
||||
```
|
||||
|
||||
(Why not use data kinds like `data Type = File | Dir`? Because that imposes
|
||||
an extension overhead of adding `{-# LANGUAGE DataKinds #-}` to every module
|
||||
you might want to write out a path type in. Given that one cannot construct
|
||||
paths of types other than these, via the operations in the module, it’s not
|
||||
a concern for me.)
|
||||
|
||||
There is a conversion function to give you back the filepath:
|
||||
|
||||
```haskell
|
||||
toFilePath :: Path b t -> FilePath
|
||||
toFilePath (Path l) = l
|
||||
```
|
||||
|
||||
Beginning from version 0.5.3, there are type-constrained versions of
|
||||
`toFilePath` with the following signatures:
|
||||
|
||||
```haskell
|
||||
fromAbsDir :: Path Abs Dir -> FilePath
|
||||
fromRelDir :: Path Rel Dir -> FilePath
|
||||
fromAbsFile :: Path Abs File -> FilePath
|
||||
fromRelFile :: Path Rel File -> FilePath
|
||||
```
|
||||
|
||||
### Parsers
|
||||
|
||||
To get a `Path` value, you need to use one of the four parsers:
|
||||
|
||||
```haskell
|
||||
parseAbsDir :: MonadThrow m => FilePath -> m (Path Abs Dir)
|
||||
parseRelDir :: MonadThrow m => FilePath -> m (Path Rel Dir)
|
||||
parseAbsFile :: MonadThrow m => FilePath -> m (Path Abs File)
|
||||
parseRelFile :: MonadThrow m => FilePath -> m (Path Rel File)
|
||||
```
|
||||
|
||||
The following properties apply:
|
||||
|
||||
* Absolute parsers will reject non-absolute paths.
|
||||
|
||||
* The only delimiter syntax accepted is the path separator; `/` on POSIX and
|
||||
`\` on Windows.
|
||||
|
||||
* Any other delimiter is rejected; `..`, `~/`, `/./`, etc.
|
||||
|
||||
* All parsers normalize into single separators: `/home//foo` → `/home/foo`.
|
||||
|
||||
* Directory parsers always normalize with a final trailing `/`. So `/home/foo`
|
||||
parses into the string `/home/foo/`.
|
||||
|
||||
It was discussed briefly whether we should just have a class for parsing
|
||||
rather than four separate parsing functions. In my experience so far, I have
|
||||
had type errors where I wrote something `like x <- parseAbsDir
|
||||
someAbsDirString` because `x` was then passed to a place that expected a
|
||||
relative directory. In this way, overloading the return value would’ve just
|
||||
been accepted. So I don’t think having a class is a good idea. Being
|
||||
explicit here doesn’t exactly waste our time, either.
|
||||
|
||||
Why are these functions in `MonadThrow`? Because it means I can have it
|
||||
return an `Either`, or a `Maybe`, if I’m in pure code, and if I’m in `IO`,
|
||||
and I don’t expect parsing to ever fail, I can use it in IO like this:
|
||||
|
||||
```haskell
|
||||
do x <- parseRelFile (fromCabalFileName x)
|
||||
foo x
|
||||
…
|
||||
```
|
||||
|
||||
That’s really convenient and we take advantage of this at FP Complete a lot.
|
||||
The instances
|
||||
|
||||
Equality, ordering and printing are simply re-using the `String` instances:
|
||||
|
||||
```haskell
|
||||
instance Eq (Path b t) where
|
||||
(==) (Path x) (Path y) = x == y
|
||||
|
||||
instance Ord (Path b t) where
|
||||
compare (Path x) (Path y) = compare x y
|
||||
|
||||
instance Show (Path b t) where
|
||||
show (Path x) = show x
|
||||
```
|
||||
|
||||
Which gives us for free the following equational properties:
|
||||
|
||||
```haskell
|
||||
toFilePath x == toFilePath y ≡ x == y -- Eq instance
|
||||
toFilePath x `compare` toFilePath y ≡ x `compare` y -- Ord instance
|
||||
toFilePath x == toFilePath y ≡ show x == show y -- Show instance
|
||||
```
|
||||
|
||||
In other words, the representation and the path you get out at the end are
|
||||
the same. Two paths that are equal will always give you back the same thing.
|
||||
|
||||
### Smart constructors
|
||||
|
||||
For when you know what a path will be at compile-time, there are
|
||||
constructors for that:
|
||||
|
||||
```haskell
|
||||
$(mkAbsDir "/home/chris")
|
||||
$(mkRelDir "chris")
|
||||
$(mkAbsFile "/home/chris/x.txt")
|
||||
$(mkRelFile "chris/x.txt")
|
||||
```
|
||||
|
||||
These will run at compile-time and underneath use the appropriate parser.
|
||||
|
||||
### Overloaded strings
|
||||
|
||||
No `IsString` instance is provided, because that has no way to statically
|
||||
determine whether the path is correct, and would otherwise have to be a
|
||||
partial function.
|
||||
|
||||
In practice I have written the wrong path format in a `$(mk… "")` and been
|
||||
thankful it was caught early.
|
||||
|
||||
### Operations
|
||||
|
||||
There is path concatenation:
|
||||
|
||||
```haskell
|
||||
(</>) :: Path b Dir -> Path Rel t -> Path b t
|
||||
```
|
||||
|
||||
Get the parent directory of a path:
|
||||
|
||||
```haskell
|
||||
parent :: Path Abs t -> Path Abs Dir
|
||||
```
|
||||
|
||||
Get the filename of a file path:
|
||||
|
||||
```haskell
|
||||
filename :: Path b File -> Path Rel File
|
||||
```
|
||||

||||
Get the directory name of a directory path:

```haskell
|
||||
dirname :: Path b Dir -> Path Rel Dir
|
||||
```

|
||||
```
|
||||
|
||||
## Review
|
||||
|
||||
Let’s review my initial list of complaints and see if they’ve been
|
||||
satisfied.
|
||||
|
||||
### Relative vs absolute confusion
|
||||
|
||||
Paths now distinguish in the type system whether they are relative or
|
||||
absolute. You can’t append two absolute paths, for example:
|
||||
|
||||
```haskell
|
||||
λ> $(mkAbsDir "/home/chris") </> $(mkAbsDir "/home/chris")
|
||||
<interactive>:23:31-55:
|
||||
Couldn't match type ‘Abs’ with ‘Rel’
|
||||
```
|
||||
|
||||
### The equality problem
|
||||
|
||||
Paths are now stringently normalized. They have to be a valid path, and they
|
||||
only support single path separators, and all directories are suffixed with a
|
||||
trailing path separator:
|
||||
|
||||
```haskell
|
||||
λ> $(mkAbsDir "/home/chris//") == $(mkAbsDir "/./home//chris")
|
||||
True
|
||||
λ> toFilePath $(mkAbsDir "/home/chris//") ==
|
||||
toFilePath $(mkAbsDir "/./home//chris")
|
||||
True
|
||||
λ> ($(mkAbsDir "/home/chris//"),toFilePath $(mkAbsDir "/./home//chris"))
|
||||
("/home/chris/","/home/chris/")
|
||||
```
|
||||
|
||||
### Unpredictable concatenation issues
|
||||
|
||||
Because of the stringent normalization, path concatenation, as seen above,
|
||||
is simply string concatenation. This is about as predictable as it can get:
|
||||
|
||||
```haskell
|
||||
λ> toFilePath $(mkAbsDir "/home/chris//")
|
||||
"/home/chris/"
|
||||
λ> toFilePath $(mkRelDir "foo//bar")
|
||||
"foo/bar/"
|
||||
λ> $(mkAbsDir "/home/chris//") </> $(mkRelDir "foo//bar")
|
||||
"/home/chris/foo/bar/"
|
||||
```
|
||||
|
||||
### Confusing files and directories
|
||||
|
||||
Now that the path type is encoded in the type system, our `</>` operator
|
||||
prevents improper appending:
|
||||
|
||||
```haskell
|
||||
λ> $(mkAbsDir "/home/chris/") </> $(mkRelFile "foo//bar")
|
||||
"/home/chris/foo/bar"
|
||||
λ> $(mkAbsFile "/home/chris") </> $(mkRelFile "foo//bar")
|
||||
<interactive>:35:1-26:
|
||||
Couldn't match type ‘File’ with ‘Dir’
|
||||
```
|
||||
|
||||
### Self-documentation
|
||||
|
||||
Now I can read the path like:
|
||||
|
||||
```haskell
|
||||
{ fooPath :: Path Rel Dir, ... }
|
||||
```
|
||||
|
||||
And know that this refers to the directory relative to some other path,
|
||||
meaning I should be careful to consider the current directory when using
|
||||
this in IO, or that I’ll probably need a parent to append to it at some
|
||||
point.
|
||||
|
||||
## In practice
|
||||
|
||||
We’ve been using this at FP Complete in a number of packages for some months
|
||||
now, it’s turned out surprisingly sufficient for most of our path work with
|
||||
only one bug found. We weren’t sure initially whether it would just be too
|
||||
much of a pain to use, but really it’s quite acceptable given the
|
||||
advantages. You can see its use all over the
|
||||
[`stack`](https://github.com/commercialhaskell/stack) codebase.
|
||||
|
||||
## Doing I/O
|
||||
|
||||
Currently any operations involving I/O can be done by using the existing I/O
|
||||
library:
|
||||
|
||||
```haskell
|
||||
doesFileExist (toFilePath fp)
|
||||
readFile (toFilePath fp)
|
||||
```
|
||||
|
||||
etc. This has problems with respect to accidentally running something like:
|
||||
|
||||
```haskell
|
||||
doesFileExist $(mkRelDir "foo")
|
||||
```
|
||||
|
||||
But I/O is currently outside the scope of what this package solves. Once you
|
||||
leave the realm of the `Path` type invariants are back to your responsibility.
|
||||
|
||||
As with the original version of this library, we’re currently building up a
|
||||
set of functions in a `Path.IO` module over time that fits our real-world
|
||||
use-cases. It may or may not appear in the path package eventually. It’ll
|
||||
need cleaning up and considering what should really be included.
|
||||
|
||||
**Edit:** There is now
|
||||
[`path-io`](https://hackage.haskell.org/package/path-io) package that
|
||||
complements the `path` library and includes complete well-typed interface to
|
||||
[`directory`](https://hackage.haskell.org/package/directory) and
|
||||
[`temporary`](https://hackage.haskell.org/package/temporary). There is work
|
||||
to add more generally useful functions from Stack's `Path.IO` to it and make
|
||||
Stack depend on the `path-io` package.
|
||||
|
||||
## Doing textual manipulations
|
||||
|
||||
One problem that crops up sometimes is wanting to manipulate
|
||||
paths. Currently the way we do it is via the filepath library and re-parsing
|
||||
the path:
|
||||
|
||||
```haskell
|
||||
parseAbsFile . addExtension "/directory/path" "ext" . toFilePath
|
||||
```
|
||||
|
||||
It doesn’t happen too often, in our experience, to the extent this needs to
|
||||
be more convenient.
|
||||
|
||||
## Accepting user input
|
||||
|
||||
Sometimes you have user input that contains `../`. The solution we went with
|
||||
is to have a function like `resolveDir`:
|
||||
|
||||
```haskell
|
||||
resolveDir :: (MonadIO m, MonadThrow m)
|
||||
=> Path Abs Dir -> FilePath -> m (Path Abs Dir)
|
||||
```
|
||||
|
||||
Which will call `canonicalizePath` which collapses and normalizes a path and
|
||||
then we parse with regular old `parseAbsDir` and we’re cooking with
|
||||
gas. This and others like it might get added to the `path` package.
|
||||
|
||||
## Comparing with existing path libraries
|
||||
|
||||
### filepath and system-filepath
|
||||
|
||||
The [filepath](http://hackage.haskell.org/package/filepath) package is
|
||||
intended as the complimentary package to be used before parsing into a Path
|
||||
value, and/or after printing from a Path value. The package itself contains
|
||||
no type-safety, instead contains a range of cross-platform textual
|
||||
operations. Definitely reach for this library when you want to do more
|
||||
involved manipulations.
|
||||
|
||||
The `system-filepath` package is deprecated in favour of `filepath`.
|
||||
|
||||
### system-canonicalpath, canonical-filepath, directory-tree
|
||||
|
||||
The
|
||||
[`system-canonicalpath`](http://hackage.haskell.org/package/system-canonicalpath)
|
||||
and the
|
||||
[`canonical-filepath`](http://hackage.haskell.org/package/canonical-filepath)
|
||||
packages both are a kind of subset of `path`. They canonicalize a string
|
||||
into an opaque path, but neither distinguish directories from files or
|
||||
absolute/relative. Useful if you just want a canonical path but doesn’t do
|
||||
anything else.
|
||||
|
||||
The [`directory-tree`](http://hackage.haskell.org/package/directory-tree)
|
||||
package contains a sum type of dir/file/etc but doesn’t distinguish in its
|
||||
operations relativity or path type.
|
||||
|
||||
### pathtype
|
||||
|
||||
Finally, we come to a path library that path is similar to: the
|
||||
[`pathtype`](http://hackage.haskell.org/package/pathtype) library. There are
|
||||
the same types of `Path Abs File` / `Path Rel Dir`, etc.
|
||||
|
||||
The points where this library isn’t enough for me are:
|
||||
|
||||
* There is an `IsString` instance, which means people will use it, and will
|
||||
make mistakes.
|
||||
|
||||
* Paths are not normalized into a predictable format, leading to me being
|
||||
unsure when equality will succeed. This is the same problem I encountered
|
||||
in `system-filepath`. The equality function normalizes, but according to
|
||||
what properties I can reason about? I don’t know.
|
||||
|
||||
```haskell
|
||||
System.Path.Posix> ("/tmp//" :: Path a Dir) == ("/tmp" :: Path a Dir)
|
||||
True
|
||||
System.Path.Posix> ("tmp" :: Path a Dir) == ("/tmp" :: Path a Dir)
|
||||
True
|
||||
System.Path.Posix> ("/etc/passwd/" :: Path a b) == ("/etc/passwd" :: Path a b)
|
||||
True
|
||||
System.Path.Posix> ("/tmp//" :: Path Abs Dir) == ("/tmp/./" :: Path Abs Dir)
|
||||
False
|
||||
System.Path.Posix> ("/tmp/../" :: Path Abs Dir) == ("/" :: Path Abs Dir)
|
||||
False
|
||||
```
|
||||
* Empty string should not be allowed, and introduction of `.` due to that
|
||||
gets weird:
|
||||
|
||||
```haskell
|
||||
System.Path.Posix> fmap getPathString (Right ("." :: Path Rel File))
|
||||
Right "."
|
||||
System.Path.Posix> fmap getPathString (mkPathAbsOrRel "")
|
||||
Right "."
|
||||
System.Path.Posix> (Right ("." :: Path Rel File)) == (mkPathAbsOrRel "")
|
||||
False
|
||||
System.Path.Posix> takeDirectory ("tmp" :: Path Rel Dir)
|
||||
.
|
||||
System.Path.Posix> (getPathString ("." :: Path Rel File) ==
|
||||
getPathString ("" :: Path Rel File))
|
||||
True
|
||||
System.Path.Posix> (("." :: Path Rel File) == ("" :: Path Rel File))
|
||||
False
|
||||
```
|
||||
|
||||
* It has functions like `<.>/addExtension` which lets you insert an
|
||||
arbitrary string into a path.
|
||||
|
||||
* Some functions let you produce nonsense (could be prevented by a stricter
|
||||
type), for example:
|
||||
|
||||
```haskell
|
||||
System.Path.Posix> takeFileName ("/tmp/" :: Path Abs Dir)
|
||||
tmp
|
||||
```
|
||||
|
||||
I’m being a bit picky here, a bit unfair. But the point is really to show
|
||||
the kind of things I tried to avoid in `path`. In summary, it’s just hard to
|
||||
know where things can go wrong, similar to what was going on in
|
||||
`system-filepath`.
|
||||
|
||||
### data-filepath
|
||||
|
||||
The [`data-filepath`](https://hackage.haskell.org/package/data-filepath) is
|
||||
also very similar, I discovered it after writing my own at work and was
|
||||
pleased to see it’s mostly the same. The main differences are:
|
||||
|
||||
* Uses `DataKinds` for the relative/absolute and file/dir distinction which
|
||||
as I said above is an overhead.
|
||||
|
||||
* Uses a GADT for the path type, which is fine. In my case I wanted to
|
||||
retain the original string which functions that work on the `FilePath`
|
||||
(`String`) type already deal with well. It does change the parsing step
|
||||
somewhat, because it parses into segments.
|
||||
|
||||
* It’s more lenient at parsing (allowing `..` and trailing `.`).
|
||||
|
||||
The API is a bit awkward to just parse a directory, requires a couple
|
||||
functions to get it (going via `WeakFilePath`), returning only an `Either`,
|
||||
and there are no functions like parent. But there’s not much to complain
|
||||
about. It’s a fine library, but I didn’t feel the need to drop my own in
|
||||
favor of it. Check it out and decide for yourself.
|
||||
|
||||
## Summary
|
||||
|
||||
There’s a growing interest in making practical use of well-typed file path
|
||||
handling. I think everyone’s wanted it for a while, but few people have
|
||||
really committed to it in practice. Now that I’ve been using `path` for a
|
||||
while, I can’t really go back. It’ll be interesting to see what new packages
|
||||
crop up in the coming year, I expect there’ll be more.

Support high-level IO operations on files/directories, utilizing ByteString
|
||||
as FilePaths.
|
||||
|
||||
This package is part of the HPath suite, also check out:
|
||||
|
||||
* [hpath](https://hackage.haskell.org/package/hpath)
|

* [hpath-filepath](https://hackage.haskell.org/package/hpath-filepath)

## Motivation
|
||||
|
||||
This is basically a fork of [directory](https://hackage.haskell.org/package/directory), but is a complete rewrite and the API doesn't follow the directory package.
|
||||
|
||||
## Differences to 'posix-paths'
|
||||
|
||||
* 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

# HPath-filepath
|

|

[![Gitter chat](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/hasufell/hpath?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge) [![Hackage version](https://img.shields.io/hackage/v/hpath-filepath.svg?label=Hackage)](https://hackage.haskell.org/package/hpath-filepath) [![Build Status](https://api.travis-ci.org/hasufell/hpath.png?branch=master)](http://travis-ci.org/hasufell/hpath) [![Hackage-Deps](https://img.shields.io/hackage-deps/v/hpath-filepath.svg)](http://packdeps.haskellers.com/feed?needle=hpath-filepath)
|
||||
|
||||
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

[![Gitter chat](https://badges.gitter.im/Join%20Chat.svg)](https://gitter.im/hasufell/hpath?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge) [![Hackage version](https://img.shields.io/hackage/v/hpath-io.svg?label=Hackage)](https://hackage.haskell.org/package/hpath-io) [![Build Status](https://api.travis-ci.org/hasufell/hpath.png?branch=master)](http://travis-ci.org/hasufell/hpath) [![Hackage-Deps](https://img.shields.io/hackage-deps/v/hpath-io.svg)](http://packdeps.haskellers.com/feed?needle=hpath-io)
|
||||
|
||||
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.

-- 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.

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`
