./wip/hs-safer-file-handles, Type-safe file handling

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ]

Branch: CURRENT, Version: 0.10, Package name: hs-safer-file-handles-0.10, Maintainer: pho

This package adds three safety features on top of the regular
System.IO file handles and operations:

* Regional file handles. Files must be opened in a region. When the
region terminates all opened files are automatically closed. The
main advantage of regions is that the handles to the opened files
can not be returned from the region which ensures no I/O with closed
files is possible.

* Explicit IOModes. The regional file handles are parameterized by the
IOMode in which they were opened. All operations on handles
explicitly specify the needed IOMode. This way it is impossible to
read from a write-only handle or write to a read-only handle for
example.

* Type-safe filepath creation and manipulation using the pathtype
package.

The primary technique used in this package is called "Lightweight
monadic regions" which was invented by Oleg Kiselyov and Chung-chieh
Shan. See:
http://okmij.org/ftp/Haskell/regions.html#light-weight
