coolname 2.2.0

Random name and slug generator

Do you want random human-readable strings?

>>> from coolname import generate_slug
>>> generate_slug()
'big-maize-lori-of-renovation'
>>> generate_slug()
'tunneling-amaranth-rhino-of-holiness'
>>> generate_slug()
'soft-cuddly-shrew-of-expertise'

Features

• Generate slugs, ready to use, Django-compatible.

  >>> from coolname import generate_slug
  >>> generate_slug()
  'qualified-agama-of-absolute-kindness'

• Generate names as sequences and do whatever you want with them.

  >>> from coolname import generate
  >>> generate()
  ['beneficial', 'bronze', 'bee', 'of', 'glee']
  >>> ' '.join(generate())
  'limber transparent toad of luck'
  >>> ''.join(x.capitalize() for x in generate())
  'CalmRefreshingTerrierOfAttraction'

• Generate names of specific length: 2, 3 or 4 words.

  >>> generate_slug(2)
  'mottled-crab'
  >>> generate_slug(3)
  'fantastic-acoustic-whale'
  >>> generate_slug(4)
  'military-diamond-tuatara-of-endeavor'

  Note: without argument, it returns a random length, but probability of 4‑word name is much higher. Prepositions and articles (of, from, the) are not counted as words.

• Use in command line:

  $ coolname
  prophetic-tireless-bullfrog-of-novelty
  $ coolname 3 -n 2 -s '_'
  wildebeest_of_original_champagne
  ara_of_imminent_luck

• Over 10¹⁰ random names.

  Words	Combinations	Example
  4	1010	talented-enigmatic-bee-of-hurricane
  3	108	ambitious-turaco-of-joviality
  2	105	prudent-armadillo

  >>> from coolname import get_combinations_count
  >>> get_combinations_count(4)
  62620779367

• Hand-picked vocabulary. sexy and demonic are about the most “offensive” words here - but there is only a pinch of them, for spice. Most words are either neutral, such as red, or positive, such as brave. And subject is always some animal, bird, fish, or insect - you can’t be more neutral than Mother Nature.

• Easy customization. Create your own rules!

  >>> from coolname import RandomGenerator
  >>> generator = RandomGenerator({
  ...   'all': {
  ...     'type': 'cartesian',
  ...     'lists': ['first_name', 'last_name']
  ...   },
  ...   'first_name': {
  ...     'type': 'words',
  ...     'words': ['james', 'john']
  ...   },
  ...   'last_name': {
  ...     'type': 'words',
  ...     'words': ['smith', 'brown']
  ...   }
  ... })
  >>> generator.generate_slug()
  'james-brown'
