#Haikus Haikus is a Python library for finding haikus in arbitrary text using NLTK. It simply finds 5 and 7 syllable phrases that form haikus in a 5,7,5 pattern.
##Installation Use pip!
pip install -e git+https://github.com/wieden-kennedy/haikus#egg=haikus##Usage It's easy to find haikus in text with Haikus. Simply instantiate a HaikuText object with your choice of text and ask it to find haikus.
from haikus import HaikuText
f = open("/tmp/my_term_paper.txt", "r")
text = HaikuText(text=f.read())
haikus = HaikuText.get_haikus()HaikuText's get_haikus() function will return a Haiku instance for every haiku in the text. Haiku's get_lines() method will return a list of lines in the haiku.
haiku = haikus[0]
print haiku.get_lines()
# oh look, a haiku from your term paper! ["abraham lincoln", "was a president one time", "he freed many slaves"]##Haiku Evaluation Haikus includes functions for evaluating Haiku objects based on their contents. Haiku's calculate_quality() method will calculate the quality of a Haiku instance based on a set of evaluators. You can use the set of weighted evaluators provided by Haikus or create your own set of weighted evaluators.
haiku.calculate_quality()
# this will return the haiku's quality according to the DEFAULT_HAIKU_EVALUATORS
MY_RAD_EVALUATORS = [
#look at these evaluator, weight tuples!
(IsAwesomeEvaluator, 1),
(ContainsDogEvaluator, 0.75),
]
haiku.calculate_quality(evaluators=MY_RAD_EVALUATORS)
#this will calculate the quality accordin to MY_RAD_EVALUATORSYou can create your own evaluators by inheriting from haiku.evaluators.HaikuEvaluator and implementing the
evaluate() method. See haiku.evaluators for some examples.
