Outdated egg!

This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for the CHICKEN 5 version of this egg, if it exists.

If it does not exist, there may be equivalent functionality provided by another egg; have a look at the egg index. Otherwise, please consider porting this egg to the current version of CHICKEN.

Documentation

Provides access to the OSSP UUID Library. This document does not supplant the OSSP UUID Library documentation.

The OSSP UUID Library is not included in this distribution. The library source is available at the above URL. See the Issues section below for more information.

UUID Variants

V1: DCE 1.1 variant UUID of version 1
V1-MC: DCE 1.1 variant UUID of version 1 with random MAC address

V4: DCE 1.1 variant UUID of version 4
V5: DCE 1.1 variant UUID of version 5

Predicates

uuid?

[procedure] (uuid? UUID) => boolean

Is UUID a uuid?

uuid-nil?

[procedure] (uuid-null? UUID) => boolean
[procedure] (uuid-nil? UUID) => boolean

Is UUID the nil-uuid?

uuid-compare

[procedure] (uuid-compare UUID1 UUID2) => integer

Returns the comparison of UUID1 and UUID2 as -1, 0, or 1.

uuid=?

[procedure] (uuid=? UUID1 UUID2) => boolean

Are UUID1 and UUID2 equal?

uuid<?

[procedure] (uuid<? UUID1 UUID2) => boolean

Does UUID1 order below UUID2?

uuid>?

[procedure] (uuid>? UUID1 UUID2) => boolean

Does UUID1 order above UUID2?

uuid<=?

[procedure] (uuid<=? UUID1 UUID2) => boolean

Does UUID1 order below or the same as UUID2?

uuid>=?

[procedure] (uuid>=? UUID1 UUID2) => boolean

Does UUID1 order above or the same as UUID2?

Operations

uuid-clear!

[procedure] (uuid-clear! UUID) => uuid

Overwrites the existing UUID with the nil-uuid.

uuid-clone

[procedure] (uuid-copy UUID) => uuid
[procedure] (uuid-clone UUID) => uuid

Returns a copy of the UUID.

make-uuid

[procedure] (make-uuid [VARIANT [NAMESPACE NAME]]) => uuid

Returns a uuid VARIANT, or the nil-uuid when missing.

The NAMESPACE and NAME are required for V3 and V5 variants.

VARIANT is a symbol.

NAMESPACE and NAME are string.

The symbols time and random are synonyms for V1 and V4, respectively.

string->uuid

[procedure] (string->uuid STRING) => uuid

Returns a new uuid from the external STRING representation.

uuid->string

[procedure] (uuid->string UUID) => string

Returns the external string representation of UUID.

uuid-load!

[procedure] (uuid-load! UUID [NAMESPACE]) => uuid

Overwrites the existing UUID with the NAMESPACE indicated uuid. When missing "nil" is assumed.

NAMESPACE is a string.

uuid-load

[procedure] (uuid-load [NAMESPACE]) => uuid

Returns a new uuid with the NAMESPACE uuid. When missing "nil" is assumed.

NAMESPACE is a string.

uuid-import

[procedure] (uuid-import STRING) => uuid

Returns a uuid from the external STRING representation.

uuid-import-binary

[procedure] (uuid-import-binary STRING) => uuid

Returns a uuid from the external STRING binary representation.

uuid-import-siv

[procedure] (uuid-import-siv STRING) => uuid

Returns a uuid from the external STRING single integer value representation.

uuid-export

[procedure] (uuid-export UUID) => string

Returns the external string representation of UUID.

uuid-export-binary

[procedure] (uuid-export-binary UUID) =>

Returns the external binary-string representation of UUID.

uuid-export-text

[procedure] (uuid-export-text UUID) => string

Returns the external text representation of UUID.

uuid-export-siv

[procedure] (uuid-export-siv UUID) => string

Returns the external single integer value representation of UUID.

Auxillary Procedures

uuid-version

[procedure] (uuid-version) => integer

Returns OSSP UUID Library version as an unsigned-long.

Errors

Errors generated by the OSSP UUID Library are signalled using a condition of (exn uuid), with properties message, and code.

Argument errors are signalled using error.

Usage

(require-extension uuid-ossp)

Notes

The uuid?. uuid-null?, uuid-compare, uuid=?, uuid<?, uuid>?, uuid<=?, uuid>=?, make-uuid, uuid-copy, uuid-clear!, string->uuid, uuid->string share the same signature as the corresponding routines in the uuid-lib extension.
Requires at least release 1.5.0 of the OSSP uuid Library.
Installation of this egg might require manual intervention. Please see the uuid-ossp-fix.[ch] files which isolate the system header confilicts caused by the OSSP uuid.h header.
The build uses the uuid-config tool to locate the proper include directory.
Reed Sheridan has pointed out that the Debian system renames the library, as an existing library of the same name already exists. For example, uuid.h is ossp/uuid.h.
