Package atomicfile provides *os.File wrapper to allow atomic file writes. Works on Linux, macOS, and Windows.
All writes will go to a temporary file.
Call Close() explicitly when you are done writing to atomically rename the file making the changes visible.
Call Abort() to discard all your writes.
This allows for a file to always be in a consistent state and never represent an in-progress write.
Standard go get:
$ go get github.com/sashka/atomicfile
import "github.com/sashka/atomicfile"
// Prepare to write a file.
f, err := atomicfile.New(path, 0o666)
// It's safe to call f.Abort() on a successfully closed file.
// Otherwise it's correct to discard the file changes.
defer f.Abort()
// Update the file.
if _, err := f.Write(content); err != nil {
return err
}
// Make chan

f.Close()
