## Hacking Overview
The main data structure for the IO related File type is in
[HSFM.FileSystem.FileType](./../src/HSFM/FileSystem/FileType.hs#L93), which
should be seen as a library. This is the entry point where
[directory contents are read](./../src/HSFM/FileSystem/FileType.hs#L465)
and the File type in general [is constructed](./../src/HSFM/FileSystem/FileType.hs#L302).
The File type uses a safe Path type under the hood instead of Strings,
utilizing the [hpath](https://github.com/hasufell/hpath) library.
Note that mostly only absolute paths are allowed on type level to improve
path and thread safety.
File operations (like copy, delete etc) are defined at
[HSFM.FileSystem.FileOperation](./../src/HSFM/FileSystem/FileOperations.hs)
which use this File type.
Only a GTK GUI is currently implemented, the entry point being
[HSFM.GUI.Gtk](./../src/HSFM/GUI/Gtk.hs). From there it flows down
to creating a [MyGUI object](./../src/HSFM/GUI/Gtk/Data.hs#L51) in
@ -61,8 +75,6 @@ This leads to the following benefits:
* we can reason about filepaths and rely on them to be valid (don't confuse that with "they exist")
* filepath functions like `(</>)` are now predictable and safe in contrast to the version from the `filepath` package
The [hpath](https://hackage.haskell.org/package/hpath) library does exactly that for us.
The only problem with this approach is that most libraries are still String
based. Some provide dedicated `Foo.ByteString` modules though, but it
might be necessary to fork libraries.

could already be out of date. There are two approaches to make this less
sucky:
* use the hinotify library on GUI level to refresh the view (and the File representation in memory) whenever the contents of a directory changes
* when we stuff something into the copy buffer, it is not saved as type `File a`, but as `Path Abs`... when the operation is finalized then the file at the given path is read and the copy/move/whatnot function carried out immediately
* when we stuff something into the copy buffer, it is not saved as type `File a`, but as `Path Abs`... when the operation is finalized via `runFileOp`, then the file at the given path is read and the copy/move/whatnot function carried out immediately
This means we should only interact with the `HSFM.FileSystem.FileOperation`
module via the operation data types `FileOperation`, `Copy` and `Move` and
the `runFileOp` function. This doesn't completely solve the problem, but for
the rest we have to trust the posix functions to throw the proper exceptions.
In addition, we don't use the `directory` package, which is dangerous
and broken. Instead, we use the [HPath.IO](https://hackage.haskell.org/package/hpath/docs/HPath-IO.html).

the posix functions, so we have proper control over the internals
and know the possible exceptions.
### Exception handling
@ -97,7 +116,7 @@ Exceptions are good. We don't want to wrap everything in Maybe/Either types
unless we want to handle failure immediately. Otherwise we need to make
sure that at least at some point IOExceptions are caught and visualized

`IOException` and [HPathIOException](https://hackage.haskell.org/package/hpath/docs/HPath-IO-Errors.html#t:HPathIOException).

It's also important to clean up stuff like filedescriptors via
functions like `bracket` directly in our low-level code in case

-- Some functions are just path-safe wrappers around

-- 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

-- 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.
