Description
|
|
===========
|
|
|
|
``shortuuid`` is a simple python library that generates concise, unambiguous,
|
|
URL-safe UUIDs.
|
|
|
|
Often, one needs to use non-sequential IDs in places where users will see them,
|
|
but the IDs must be as concise and easy to use as possible. ``shortuuid`` solves
|
|
this problem by generating uuids using Python's built-in ``uuid`` module and then
|
|
translating them to base57 using lowercase and uppercase letters and digits, and
|
|
removing similar-looking characters such as l, 1, I, O and 0.

Installation
|
|
------------
|
|
|
|
To install ``shortuuid`` you need:
|
|
|
|
* Python 2.5 or later in the 2.x line (earlier than 2.6 not tested), or any 3.x.
|
|
|
|
If you have the dependencies, you have multiple options of installation:
|
|
|
|
* With pip (preferred), do ``pip install shortuuid``.
|
|
* With setuptools, do ``easy_install shortuuid``.
|
|
* To install the source, download it from
|
|
https://github.com/stochastic-technologies/shortuuid and do
|
|
``python setup.py install``.
|
|
|
|
Usage
|
|
-----
|
|
|
|
To use ``shortuuid``, just import it in your project like so:
|
|
|
|
>>> import shortuuid
|
|
|
|
You can then generate a short UUID:
|
|
|
|
>>> shortuuid.uuid()
|
|
'vytxeTZskVKR7C7WgdSP3d'
|
|
|
|
If you prefer a version 5 UUID, you can pass a name (DNS or URL) to the call and
|
|
it will be used as a namespace (uuid.NAMESPACE_DNS or uuid.NAMESPACE_URL) for the
|
|
resulting UUID:
|
|
|
|
>>> shortuuid.uuid(name="example.com")
|
|
'wpsWLdLt9nscn2jbTD3uxe'
|
|
>>> shortuuid.uuid(name="http://example.com")
|
|
'c8sh5y9hdSMS6zVnrvf53T'
|
|
|
|
You can also generate a cryptographically secure random string (using
|
|
`os.urandom()`, internally) with:
|
|
|
|
>>> shortuuid.ShortUUID().random(length=22)
|
|
'RaF56o2r58hTKT7AYS9doj'
|
|
|
|
|
|
To see the alphabet that is being used to generate new UUIDs:
|
|
|
|
>>> shortuuid.get_alphabet()
|
|
'23456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz'
|
|
|
|
If you want to use your own alphabet to generate UUIDs, use ``set_alphabet()``:
|
|
|
|
>>> shortuuid.set_alphabet("aaaaabcdefgh1230123")
|
|
>>> shortuuid.uuid()
|
|
'0agee20aa1hehebcagddhedddc0d2chhab3b'
|
|
|
|
``shortuuid`` will automatically sort and remove duplicates from your alphabet to
|
|
ensure consistency:
|
|
|
|
>>> shortuuid.get_alphabet()
|
|
'0123abcdefgh'
|
|
|
|
If the default 22 digits are too long for you, you can get shorter IDs by just
|
|
truncating the string to the desired length. The IDs won't be universally unique
|
|
any longer, but the probability of a collision will still be very low.
|
|
|
|
To serialize existing UUIDs, use ``encode()`` and ``decode()``:
|
|
|
|
>>> import uuid ; u = uuid.uuid4() ; u
|
|
UUID('6ca4f0f8-2508-4bac-b8f1-5d1e3da2247a')
|
|
>>> s = shortuuid.encode(u) ; s
|
|
'cu8Eo9RyrUsV4MXEiDZpLM'
|
|
>>> shortuuid.decode(s) == u
|
|
True
|
|
>>> short = s[:7] ; short
|
|
'cu8Eo9R'
|
|
>>> h = shortuuid.decode(short)
|
|
UUID('00000000-0000-0000-0000-00b8c0b9f952')
|
|
>>> shortuuid.decode(shortuuid.encode(h)) == h
|
|
True
|
|
|
|
Class-based usage
|
|
-----------------
|
|
|
|
If you need to have various alphabets per-thread, you can use the `ShortUUID` class, like so:
|
|
|
|
>>> su = shortuuid.ShortUUID(alphabet="01345678")
|
|
>>> su.uuid()
|
|
'034636353306816784480643806546503818874456'
|
|
>>> su.get_alphabet()
|
|
'01345678'
|
|
>>> su.set_alphabet("21345687654123456")
|
|
>>> su.get_alphabet()
|
|
'12345678'
|
|
|
|
Command-line usage
|
|
------------------
|
|
|
|
`shortuuid` provides a simple way to generate a short UUID in a terminal::
|
|
|
|
$ python3 -m shortuuid
|
|
fZpeF6gcskHbSpTgpQCkcJ
|
|
|
|
|
|
(Replace `python3` with `py` if you are using Windows)
|
|
|
|
|
|
Compatibility note
|
|
------------------
|
|
|
|
Versions of ShortUUID prior to 1.0.0 generated UUIDs with their MSB last, i.e.
|
|
reversed. This was later fixed, but if you have some UUIDs stored as a string
|
|
with the old method, you need to pass `legacy=True` to `decode()` when
|
|
converting your strings back to UUIDs.
|
|
|
|
That option will go away in the future, so you will want to convert your UUIDs
|
|
to strings using the new method. This can be done like so:
|
|
|
|
>>> new_uuid_str = encode(decode(old_uuid_str, legacy=True))
