Variables

Type Visibility Attributes Name Initial
integer, public, parameter :: UUID_LEN = 32

Hex UUIDv4 length.
integer, public, parameter :: UUID_FULL_LEN = 36

Full UUIDv4 length (with hyphens).
character(len=*), public, parameter :: UUID_DEFAULT = repeat('0', UUID_LEN)

Default ID (hex).

Functions

public impure elemental function dm_uuid4() result(uuid)

Generates random UUIDv4 (RFC 4122) in hexadecimal format, i.e., without hyphens (32 characters long). The PRNG has to be seeded before the first invocation by calling dm_init() once.

Arguments

None

Return Value character(len=UUID_LEN)

public impure elemental function dm_uuid4_hyphens() result(uuid)

Returns UUIDv4 with hyphens (36 characters long). The PRNG has to be seeded before the first invocation by calling dm_init() once.

Arguments

None

Return Value character(len=UUID_FULL_LEN)

public pure elemental function dm_uuid4_hyphenize(uuid) result(str)

Returns given UUID with hyphens, i.e., turns string 00000000000000000000000000000000 into 00000000-0000-0000-0000-000000000000. The function does not validate the passed indentifier.

Arguments

Type IntentOptional Attributes Name
character(len=UUID_LEN), intent(in) :: uuid

Return Value character(len=UUID_FULL_LEN)

public pure elemental function dm_uuid4_is_valid(uuid) result(valid)

Returns .true. if given UUID in hex format is a valid UUIDv4. Only lower-case letters are valid.

Arguments

Type IntentOptional Attributes Name
character(len=*), intent(in) :: uuid

UUIDv4 to validate.

Return Value logical
