Vasuki

About
Vasuki generates different kinds of random unique identifiers, tokens, and words.
It can be used as a library and as an HTTP service, aiming to provide effortless
identifier generation for your applications.
A public instance of the HTTP service is available at https://api.hiveeyes.org/vasuki/.

Synopsis
# UUIDv4 universally unique identifier.
vasuki uuid

# ULID universally unique lexicographically sortable identifier.
vasuki ulid

# Gibberish random, pronounceable pseudo-words
vasuki gibberish

# MomentName short epoch slugs
vasuki moment

# Nagamani19 short, unique, non-sequential identifier.
vasuki naga19

Install
Prerequisites
pip install vasuki
With service API:
pip install 'vasuki[service]'
Please note this software is a work in progress, and its interfaces may change.
For those reasons, if you use it as a dependency in your own programs, version
pinning is always recommended.

Features

Unique ID generators

UUIDv4 universally unique identifier
ULID universally unique lexicographically sortable identifier
Gibberish random, pronounceable pseudo-words
MomentName, a short epoch slug
Nagamani19, a short, unique, non-sequential identifier based on Hashids
and a custom Epoch starting on January 1, 2019.

Time and randomness is usually taking from the system
as implemented by the libraries underpinning this package.

Slugifiers

six-nibble-name converts six nibbles (three bytes) into a 4-character name

Optional service API
The fine responder library optionally exposes the machinery as HTTP API.

Examples

Identifier generation
# UUIDv4
vasuki uuid
d192b464-d32c-48f1-9c23-0fe04a4e8133

# ULID
vasuki ulid
01DEFKXYCJ0E91DQY0YPWZY01D

# Gibberish
vasuki gibberish
shoomly

# MomentName
vasuki moment
Zese

# Nagamani19
vasuki naga19
Xm3k6mWq

With transformations
Vasuki can apply uppercase or lowercase transformation to the
generated identifier or word:
# UUIDv4, uppercase
vasuki uuid --upper
43FA0272-CA48-40AE-8CC1-204302D91D89

# ULID, lowercase
vasuki ulid --lower
01defkz01k47dqkvcyhy0mz06e

With variable word length
vasuki gibberish --size medium
schreblyiopp

Slug tools
vasuki slug 42 --format=sixnibble
Baca

Multiple tokens at once
vasuki naga19 --count 10
vasuki gibberish --size large --count 50

HTTP API
Start the Vasuki service as daemon:
vasuki service
Example requests would look like:
# UUIDv4
/unique/uuid

# Uppercase UUIDv4
/unique/uuid?upper=true

# Multiple ULIDs
/unique/ulid?count=10

# Very short Nagamani19
/unique/naga19?size=small

Development
Acquire sources:
git clone https://github.com/daq-tools/vasuki
cd vasuki
Install development sandbox:
python3 -m venv .venv
source .venv/bin/activate
pip install --editable='.[service,develop,docs,test]'
vasuki --version
Run linter and software tests:
poe check

Disclaimer
The algorithms and procedures curated here generate different kinds of random and
pseudo-random identifiers, tokens, names or passwords.
While some generated tokens max out on the randomness and uniqueness
aspects like UUIDs, others compromise on the time vs. space domain but focus
more on human memorability and empathize with their common sense and humor.
Saying that, it is important to understand their properties and features when using
those identifiers in different contexts. YMMV.
For more in-depth information, enjoy reading Understanding UUIDs, ULIDs and String
Representations and its corresponding discussion.

Etymology
Kurma is one of the avatars of Vishnu. He appears in the form of a tortoise
or turtle to support the foundation of the cosmos, while the gods and demons
churn the cosmic ocean with the help of serpent Vasuki to produce the nectar
of immortality.
Vasuki is a naga serpent king, occasionally coiling around Kurma’s or Shiva’s
neck, who blessed and wore him as an ornament. He is described as having
a gem called Nagamani on his head.
