chirptext 0.1a7

ChirpText is a collection of text processing tools for Python.

ChirpText is a collection of text processing tools for Python. It is not meant to be a powerful tank like the popular NTLK but a small package which you can pip-install anywhere and write a few lines of code to process textual data.

Main features

• Quick text-based report generation

• Web fetcher with responsible web crawling ethics (support caching out of the box)

• Text annotation framework (TTL, a.k.a TextTagLib format) which can import/export JSON or human-readable text files

• CSV helper functions

• Helper functions and useful data for processing English, Japanese, Chinese and Vietnamese.

• Console application template

• Application configuration files management which can make educated guess about config files’ whereabouts

Installation

pip install chirptext
# pip script sometimes doesn't work properly, so you may want to try this instead
python3 -m pip install chirptext

Note: chirptext library does not support Python 2 anymore. Please update to Python 3 to use this package.

Sample codes

Web fetcher

from chirptext import WebHelper

web = WebHelper('~/tmp/webcache.db')
data = web.fetch('https://letuananh.github.io/test/data.json')
data
>>> b'{ "name": "Kungfu Panda" }\n'
data_json = web.fetch_json('https://letuananh.github.io/test/data.json')
data_json
>>> {'name': 'Kungfu Panda'}

Using Counter

from chirptext import Counter, TextReport
from chirptext.leutile import LOREM_IPSUM

ct = Counter()
vc = Counter()  # vowel counter
for char in LOREM_IPSUM:
    if char == ' ':
        continue
    ct.count(char)
    vc.count("Letters")
    if char in 'auieo':
        vc.count("Vowels")
    else:
        vc.count("Consonants")
vc.summarise()
ct.summarise(byfreq=True, limit=5)

Output

Letters: 377
Consonants: 212
Vowels: 165
i: 42
e: 37
t: 32
o: 29
a: 29

Sample TextReport

# a string report
rp = TextReport()  # by default, TextReport will write to standard output, i.e. terminal
rp = TextReport(TextReport.STDOUT)  # same as above
rp = TextReport('~/tmp/my-report.txt')  # output to a file
rp = TextReport.null()  # ouptut to /dev/null, i.e. nowhere
rp = TextReport.string()  # output to a string. Call rp.content() to get the string
rp = TextReport(TextReport.STRINGIO)  # same as above

# TextReport will close the output stream automatically by using the with statement
with TextReport.string() as rp:
    rp.header("Lorem Ipsum Analysis", level="h0")
    rp.header("Raw", level="h1")
    rp.print(LOREM_IPSUM)
    rp.header("Top 5 most common letters")
    ct.summarise(report=rp, limit=5)
    print(rp.content())

Output
