System.IO.HVFS.InstanceHelpers
Description
Utilities for creating instances of the items defined in System.IO.HVFS.

- newMemoryVFS :: [MemoryNode] -> IO MemoryVFS
- newMemoryVFSRef :: IORef [MemoryNode] -> IO MemoryVFS
- type MemoryNode = (String, MemoryEntry)
- data MemoryEntry
- nice_slice :: String -> [String]
- getFullPath :: HVFS a => a -> String -> IO String
- getFullSlice :: HVFS a => a -> String -> IO [String]
HVFSStat objects
data SimpleStat Source
A simple System.IO.HVFS.HVFSStat class that assumes that everything is either a file or a directory.
Constructors

Instances
HVFS objects & types
MemoryVFS
An in-memory read/write filesystem. Think of it as a dynamically resizable ramdisk written in Haskell.
newMemoryVFS :: [MemoryNode] -> IO MemoryVFS Source
Create a new MemoryVFS object from an existing tree.
An empty filesystem may be created by using [] for the parameter.
newMemoryVFSRef :: IORef [MemoryNode] -> IO MemoryVFS Source
Create a new MemoryVFS object using an IORef to an
existing tree.
type MemoryNode = (String, MemoryEntry) Source
The basic node of a MemoryVFS. The String corresponds to the filename,
and the entry to the contents.
data MemoryEntry Source
The content of a file or directory in a MemoryVFS.
Constructors
| MemoryDirectory [MemoryNode] | |
| MemoryFile String |

Utilities
nice_slice :: String -> [String] Source
Similar to NameManip but the first element
won't be /.
nice_slice "/" -> [] nice_slice "/foo/bar" -> ["foo", "bar"]
getFullPath :: HVFS a => a -> String -> IO String Source
Gets a full path, after investigating the cwd.
getFullSlice :: HVFS a => a -> String -> IO [String] Source
Gets the full path via getFullPath, then splits it via nice_slice.
