pytracery

You can install the tracery package using pip.

pip install tracery

Alternatively, you can download the source code and install it manually using setup.py.

python setup.py install

To use tracery in Python, define your grammar rules using a Python dictionary. You then initialize a tracery.Grammar object with these rules. You can also add modifiers (like base_english) to enable transformations like capitalization. Use grammar.flatten() with a rule name enclosed in # symbols (e.g., "#origin#") to generate the expanded text.

import tracery
from tracery.modifiers import base_english

rules = {
    'origin': '#hello.capitalize#, #location#!',
    'hello': ['hello', 'greetings', 'howdy', 'hey'],
    'location': ['world', 'solar system', 'galaxy', 'universe']
}

grammar = tracery.Grammar(rules)
grammar.add_modifiers(base_english)
print(grammar.flatten("#origin#"))  # prints, e.g., "Hello, world!"

You can run the tracery module from the command line to generate text from a JSON Tracery grammar file.

Arguments:

• json: The input JSON file containing the grammar.
• number (optional): The number of lines to generate. Defaults to 1.

Examples:

Generate one line:

python -m tracery potterpapers.json

Generate three lines:

python -m tracery potterpapers.json 3
