[![Build Status](https://travis-ci.org/dchest/safefile.svg)](https://travis-ci.org/dchest/safefile) [![Windows Build status](https://ci.appveyor.com/api/projects/status/owlifxeekg75t2ho?svg=true)](https://ci.appveyor.com/project/dchest/safefile)

Go package safefile implements safe "atomic" saving of files.

Instead of truncating and overwriting the destination file, it creates a
temporary file in the same directory, writes to it, and then renames the
temporary file to the original name when calling Commit.


### Installation

// Created temporary file /home/ken/sf-ppcyksu5hyw2mfec.tmp

defer f.Close()

_, err = io.WriteString(f, "Hello world")
if err != nil {
	// ...

// Wrote "Hello world" to /home/ken/sf-ppcyksu5hyw2mfec.tmp

err = f.Commit()
