User Guide

All random strings are generated by methods of the Fabulist class. Have a look at the Reference Guide for details.

Some Examples

This code:

from fabulist import Fabulist
fab = Fabulist()

# Print a random noun:
print(fab.get_word("noun"):

# Print a random adjective, tagged 'positive':
print(fab.get_word("adj", "#positive"):

# Print a random name, prefix with Mr./Mrs. and allow a middle-initial:
print(fab.get_name("mr:middle"):

# Print three random fragments, prefix with a/an:
for s in fab.generate_quotes("Look, $(noun:an:#animal)!", 3):
    print(s)

will produce something like this:

obligation
kind
Mrs. Julia P. Hughes
Look, a tiger
Look, an eagle!
Look, a bug!

General Template Syntax

Templates are plain strings with embedded macros. Macros are formatted like $(...) and contain a word-type and optionally one or more modifiers, separated by colons (":"), for example
$(noun) or $(noun:plural:#animal).

These macros can be embedded into template strings and will be replaced by random variations: "Look at the beautiful $(noun:plural:#animal)!"

Supported Word Types

  • adj: Adjective
    Word-form modifiers: comp, super, antonym.
    Tags: #negative, #positive
  • adv: Adverb
    Word-form modifiers: comp, super, antonym.
    Tags: #degree, #manner, #negative, #place, #positive, #time
  • noun Noun
    Word-form modifiers: plural
    Tags: animal
  • verb: Verb
    Word-form modifiers: ing, past, pp, s
    Tags: -
  • @<num>: Reference
    A special type to reference another macro in the template (see :=<num> modifier below)

NOTE: Use uppercase word-type name for capitalized results, e.g. $(Noun).
NOTE: The :antonym modifier is not yet implemented.

Special Word Types:

  • name: Generate person names
    See Modifiers for Names below.
  • num: Generate random numbers
    See Modifiers for Numbers below.
  • pick: Generate random value from a selection
    See Modifiers for Choices below.

Modifiers

Word Form Modifiers

By default, words are generated in their base form ('lemma'). At most one word-form modifier may be added to change this:

  • :comp Comparative (adj, adv)
    $(adv) => "fast", $(adj:comp) => "faster"
  • :ing (verbs only)
    $(verb) => "run", $(verb:ing) => "running"
  • :past past form (verbs only)
    $(verb) => "arise", $(verb:past) => "arose"
  • :plural (nouns only)
    $(noun) => "injury", $(noun:plural) => "injuries"
  • :pp past perfect form (verbs only)
    $(verb) => "arise", $(verb:pp) => "arisen"
  • :s -s/-es form (verbs only)
    $(verb) => "bash", $(verb:s) => "bashes"
  • :super superlative (adj, adv)
    $(adj) => "big", $(adj:super) => "biggest"

Additional Modifiers

These modifiers can used in addition to one word-form modifier:

  • :an
    Prepend "a " or "an "
    $(noun) => "essay", $(noun:an) => "an essay"
  • :antonym
    Adverbs and adjectives only: Use the opposite word. This is especially useful in combination with back-references:
    "Don't be $(adj:=1). Be $(@1:antonym) instead!"
    (NOTE: Not yet implemented!)
  • :#<tags>
    Only allow results tagged with this category.
    Pass multiple tags separated by '|', e.g.:
    $(noun:#animal), $(adv:#manner|positive)
    Note that first names are tagged with #f and/or #m for female/male:
    $(name:#m) => "John Doe"
  • :=<num>
    Store result for back-reference using @<num>.
    "One $(noun:=1) is good, but two $(@1:plural) are better."

Modifiers for Names

Names are produced by the Fabulist.get_name() method or using a $(name) macro.

These modifiers are available for names only:

  • :first only use first name
    $(name) => "Diana Chapman", $(name:first) => "Diana"
  • :last only use last name
    $(name) => "Diana Chapman", $(name:last) => "Chapman"
  • :middle generate a middle initial
    $(name) => "Diana Chapman", $(name:middle) => "Diana S. Chapman"
  • :mr prepend "Mr." or "Mrs."
    $(name) => "Diana Chapman", $(name:mr) => "Mrs. Diana Chapman"

NOTE: If neither :first nor :last is given, it is assumed that both parts are requested.

NOTE: Use #m or #f tags to restrict to male/female names:
$(name:#m) => "George Clarkson", $(name:first:#f) => Cindy

Modifiers for Numbers

Random numbers within a given range are produced by the Fabulist.get_number() method or using a $(num) macro.

The num word type only accepts on modifier with a special syntax:

  • $(num:min,max,width), e.g.
    $(num:1,999,3) => "042"
  • $(num:min,max)
    $(num:1,999) => "42"
  • $(num:max)
    $(num:999) => "42"

Modifiers for Choices

Random numbers within a given range are produced by the Fabulist.get_choice() method or using a $(pick) macro.

$(pick:CHOICES) where CHOICES may be a

  • A comma separated list of strings:
    $(pick:foo,bar,baz) => "bar"
  • A single string of characters
    $(pick:abc) => "c"

Special characters can be escaped by a backslash:
$(pick:!#\,\:) => ","

NOTE: It is recommended to use the raw string syntax (r"...") to ensure that the backslash is always passed correctly:
get_quote(r"$(pick:!#\:)")

Tips & Tricks

Mix fabulist macros with standard python formatting to insert random numbers for example:

import random
from fabulist import Fabulist

fab = Fabulist()
count = random.randint(2, 100)
color = random.choice(["red", "green", "yellow"])
template = "I need {count} {color} $(noun:plural).".format(count=count, color=color)
res = fab.get_quote(template)

Load additional custom word list from a file or static list. Note that the data formats must match the word list type.

fab = Fabulist()
# Load stock lists
fab.load()
# Add entries from custom file
fab.verb_list.load("my/verbs.txt")
# Add entries dynamically
data = [
  {"lemma": "The Beatles", "plural": False, "tags": ["band"]},
  {"lemma": "Rolling Stones", "plural": False, "tags": ["band"]},
  {"lemma": "foobar"},
  ]
for d in data:
  fab.noun_list.add_entry(d)
fab.update_data()

Generate Blind Text

In addition to the above functionalities, Fabulist also features some methods to produce blind text, also known as Lorem Ipsum.

See the Fabulist.get_lorem_*() methods for details.

Some examples here:

>>> fab.get_lorem_words(10)
['tation', 'placerat', 'officia', 'blandit', 'nisi', 'elit', 'eu', 'mazim', 'sadipscing', 'suscipit']

>>> fab.get_lorem_sentence()
Dolores takimata lorem nihil dignissim officia dolore voluptate nostrud commodo deserunt.

>>> fab.get_lorem_paragraph(3, dialect="pulp", entropy=1)
Do you see any Teletubbies in here? Do you see a slender plastic tag clipped to my shirt with my name printed on it? Do you see a little Asian child with a blank expression on his face sitting outside on a mechanical helicopter that shakes when you put quarters in it?

>>> fab.get_lorem_paragraph(3, dialect="trappatoni")
Es gibt keine deutsche Mannschaft spielt offensiv und die Name offensiv wie Bayern. Ist klar diese Wörter, ist möglich verstehen, was ich hab gesagt? Danke. Offensiv, offensiv ist wie machen wir in Platz.

>>> fab.get_lorem_paragraph(3, dialect="faust")
Zerstoben ist das freundliche Gedränge, Er scheint mir, mit Verlaub von Ew. Gnaden, Mir geht es wie der Katze mit der Maus.

>>> fab.get_lorem_paragraph(3, dialect="romeo")
Would I were sleep and peace, so sweet to rest! That monthly changes in her circled orb, I shall forget, to have thee still stand there,

>>> fab.get_lorem_text(3, keep_first=True)
