func DefaultString ¶

func DefaultString(value, defaultValue string) string

DefaultString returns the value if it's not empty, otherwise returns the default value

func ExpandPath ¶

func ExpandPath(path string) (string, error)

func ExpandPathPOSIX ¶

func ExpandPathPOSIX(path string) (string, error)

p, err := ExpandPathPOSIX("~/test")
if err != nil {
	log.Fatal(err)
}

_, last := filepath.Split(p)
fmt.Println(last)

p, _ = ExpandPathPOSIX("~NONEXISTINGUSER/path/to/file")
fmt.Println(p)

p, _ = ExpandPathPOSIX("/path/to/file/tilde/~")
fmt.Println(p)

p, _ = ExpandPathPOSIX("")
fmt.Println(p)

p, _ = ExpandPathPOSIX("")
fmt.Println(p)

Output:
test
~NONEXISTINGUSER/path/to/file
/path/to/file/tilde/~

func GenerateUUID ¶

func GenerateUUID() string

GenerateUUID generates a random UUID v4 string. Returns a 36-character UUID in format "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx".

Example:

id := utils.GenerateUUID()
// Output: "550e8400-e29b-41d4-a716-446655440000"

func GenerateUUIDShort ¶

func GenerateUUIDShort() string

GenerateUUIDShort generates a short 8-character UUID string. Higher collision probability than full UUID - use carefully in production.

Example:

id := utils.GenerateUUIDShort()
// Output: "550e8400"

func GenerateUUIDv5 ¶

func GenerateUUIDv5(namespace uuid.UUID, fields []string) (string, error)

GenerateUUIDv5 generates a deterministic UUID v5 from namespace and fields. Same inputs always produce the same UUID. Fields are joined with '|' separator.

Parameters:

• namespace: UUID namespace (e.g., uuid.NameSpaceDNS)
• fields: Non-empty strings to generate UUID from

Returns error if fields is empty or contains empty strings.

Example:

id, err := utils.GenerateUUIDv5(uuid.NameSpaceDNS, []string{"user", "john.doe"})
