var DefaultDirPerms = os.FileMode(0750)
DefaultDirPerms is default permissions for directories
View Source
var DefaultFilePerms = os.FileMode(0640)
DefaultFilePerms is default permissions for files
View Source
var Dir = os.TempDir()
Dir is path to temporary directory
View Source
var ErrNilTemp = fmt.Errorf("Temp struct is nil")
ErrNilTemp is returned if temp struct is nil

Types ¶
type Temp ¶
type Temp struct {
Dir string
DirPerms os.FileMode
FilePerms os.FileMode
// contains filtered or unexported fields
}
Temp is basic temp struct
func NewTemp ¶
NewTemp creates new Temp structure
Example ¶
tmp, err := NewTemp()
if err != nil {
panic(err.Error())
}
tmp.DirPerms = 0700
tmp.FilePerms = 0600
Output:
func (*Temp) Clean ¶
func (t *Temp) Clean()
Clean removes all temporary objects (files and directories)
Example ¶
tmp, err := NewTemp()
if err != nil {
panic(err.Error())
}
tmp.MkDir()
// All temporary data (directories and files) will be removed
tmp.Clean()
Output:
func (*Temp) MkDir ¶
MkDir creates temporary directory
Example ¶
tmp, err := NewTemp()
if err != nil {
panic(err.Error())
}
// Create a temporary file with an auto-generated name and suffix "myapp"
// The suffix is optional and can be omitted.
tmpDir, err := tmp.MkDir("myapp")
if err != nil {
panic(err.Error())
}
err = os.WriteFile(tmpDir+"/test.txt", []byte("Test data\n"), 0644)
if err != nil {
panic(err.Error())
}
Output:
func (*Temp) MkFile ¶
MkFile creates temporary file
Example ¶
tmp, err := NewTemp()
if err != nil {
panic(err.Error())
}
// Create a temporary file with an auto-generated name and suffix ".txt"
// The suffix is optional and can be omitted.
fd, filename, err := tmp.MkFile(".txt")
if err != nil {
panic(err.Error())
}
defer fd.Close()
fmt.Fprint(fd, "Test data\n")
fmt.Printf("Test data written to %s\n", filename)
Output:
func (*Temp) MkName ¶
MkName returns name for temporary object (file or directory)
Example ¶
tmp, err := NewTemp()
if err != nil {
panic(err.Error())
}
// Create a temporary file with an auto-generated name and suffix ".txt"
// The suffix is optional and can be omitted.
filename := tmp.MkName(".txt")
if filename == "" {
panic("Can't create name for temporary file")
}
err = os.WriteFile(filename, []byte("Test data\n"), 0644)
if err != nil {
panic(err.Error())
}
