Malicious npm Package Targets Solana Developers and Hijacks Funds
A malicious npm package targets Solana developers, rerouting funds in 2% of transactions to a hardcoded address.
clean-text
User-generated content on the Web and in social media is often dirty. Preprocess your scraped data with clean-text
to create a normalized text representation. For instance, turn this corrupted input:
A bunch of \\u2018new\\u2019 references, including [Moana](https://en.wikipedia.org/wiki/Moana_%282016_film%29).
»Yóù àré rïght <3!«
into this clean output:
A bunch of 'new' references, including [moana](<URL>).
"you are right <3!"
clean-text
uses ftfy, unidecode and numerous hand-crafted rules, i.e., RegEx.
To install the GPL-licensed package unidecode alongside:
pip install clean-text[gpl]
You may want to abstain from GPL:
pip install clean-text
NB: This package is named clean-text
and not cleantext
.
If unidecode is not available, clean-text
will resort to Python's unicodedata.normalize for transliteration.
Transliteration to closest ASCII symbols involes manually mappings, i.e., ê
to e
.
unidecode
's mapping is superiour but unicodedata's are sufficent.
However, you may want to disable this feature altogether depending on your data and use case.
To make it clear: There are inconsistencies between processing text with or without unidecode
.
from cleantext import clean
clean("some input",
fix_unicode=True, # fix various unicode errors
to_ascii=True, # transliterate to closest ASCII representation
lower=True, # lowercase text
no_line_breaks=False, # fully strip line breaks as opposed to only normalizing them
no_urls=False, # replace all URLs with a special token
no_emails=False, # replace all email addresses with a special token
no_phone_numbers=False, # replace all phone numbers with a special token
no_numbers=False, # replace all numbers with a special token
no_digits=False, # replace all digits with a special token
no_currency_symbols=False, # replace all currency symbols with a special token
no_punct=False, # remove punctuations
replace_with_punct="", # instead of removing punctuations you may replace them
replace_with_url="<URL>",
replace_with_email="<EMAIL>",
replace_with_phone_number="<PHONE>",
replace_with_number="<NUMBER>",
replace_with_digit="0",
replace_with_currency_symbol="<CUR>",
lang="en" # set to 'de' for German special handling

Carefully choose the arguments that fit your task. The default parameters are listed above.
You may also only use specific functions for cleaning. For this, take a look at the source code.
So far, only English and German are fully supported. It should work for the majority of western languages. If you need some special handling for your language, feel free to contribute. 🙃
clean-text
with scikit-learn
There is also scikit-learn compatible API to use in your pipelines. All of the parameters above work here as well.
pip install clean-text[gpl,sklearn]
pip install clean-text[sklearn]
from cleantext.sklearn import CleanTransformer
cleaner = CleanTransformer(no_punct=False, lower=False)
cleaner.transform(['Happily clean your text!', 'Another Input'])

Pull requests are especially welcomed when they fix bugs or improve the code quality.
If you don't like the output of clean-text
, consider adding a test with your specific input and desired output.
