| Synopsis |
|
|
|
|
| HVFSStat objects
|
|
| data SimpleStat |
| A simple System.IO.HVFS.HVFSStat
class that assumes that everything is either a file
or a directory.
| | Constructors | | SimpleStat | | | isFile :: Bool | True if file, False if directory
| | fileSize :: FileOffset | Set to 0 if unknown or a directory

|
| HVFS objects & types
|
|
| MemoryVFS
|
|
| data MemoryVFS |
| An in-memory read/write filesystem. Think of it as a dynamically
resizable ramdisk written in Haskell.
| | Instances | |
|
|
| newMemoryVFS :: [MemoryNode] -> IO MemoryVFS |
| 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 |
| Create a new MemoryVFS object using an IORef to an
existing tree.
|
|
| type MemoryNode = (String, MemoryEntry) |
| The basic node of a MemoryVFS. The String corresponds to the filename,
and the entry to the contents.
|
|
| data MemoryEntry |
| The content of a file or directory in a MemoryVFS.
| | Constructors | | | Instances | |
|
|
| Utilities
|
|
| nice_slice :: String -> [String] |
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 |
| Gets a full path, after investigating the cwd.
|
|
| getFullSlice :: HVFS a => a -> String -> IO [String] |
| Gets the full path via getFullPath, then splits it via nice_slice.
