README

tempfile

An implementation of ioutil.TempFile, but also with an additional parameter for a deterministic suffix.

This is a workaround for https://github.com/golang/go/issues/4896.

Example

import "github.com/tink-ab/tempfile"

myFile, err := tempfile.TempFile("", "my-prefix", "my-suffix")
if err != nil {
    handleError(err)
}
defer myFile.Close()
defer func() {
    if err := os.Remove(myFile.Name()); err != nil {
        handleRemovalError(err)
    }
}()

Functions

func TempFile

func TempFile(dir, prefix string, suffix string) (f *os.File, err error)

TempFile creates a new temporary file in the directory dir with a name beginning with prefix and ending with suffix, opens the file for reading and writing, and returns the resulting *os.File. If dir is the empty string, TempFile uses the default directory for temporary files (see os.TempDir). Multiple programs calling TempFile simultaneously will not choose the same file. The caller can use f.Name() to find the pathname of the file. It is the caller's responsibility to remove the file when no longer needed.
