libghc-atomic-write-dev - 0.2.1.0-1+b1 main

Atomically write to a file on POSIX-compliant systems while preserving
permissions.
.
On most Unix systems, `mv` is an atomic operation. This makes it simple to
write to a file atomically just by using the mv operation. However, this will
destroy the permissions on the original file. This library does the following
to preserve permissions while atomically writing to a file:
.
* If an original file exists, take those permissions and apply them to the
temp file before `mv`ing the file into place.
.
* If the original file does not exist, create a following with default
permissions (based on the currently-active umask).
.
This way, when the file is `mv`'ed into place, the permissions will be the
ones held by the original file.
.
This library is based on similar implementations found in common libraries in
Ruby and Python.
.
This package provides a library for the Haskell programming language.
