Profy

Profy is a Python fork of Blaspsoft/blasp, focused on the core profanity filtering engine rather than Laravel integration. It ports Blasp's dictionary-driven, obfuscation-aware matching into a standalone Python package.

The repository lives at mantleCurve/profy.

Install

pip install profy-filter

The import package is profy:

from profy import filter_text, clean_text, check_text

result = filter_text("This is f-uuck!ng noisy")

print(result.is_offensive)      # True
print(result.clean)             # This is ********* noisy
print(result.unique_words)      # ['fucking']
print(result.score)             # severity-weighted score from 0 to 100

assert check_text("f**k")
assert clean_text("shit") == "****"

Development

python -m pip install -e ".[dev]"
python -m pytest

Reuse a Filter

Create a ProfanityFilter when you need to process many strings with the same options.

from profy import ProfanityFilter, Severity

shield = ProfanityFilter(
    languages=["english", "spanish"],
    mask="#",
    minimum_severity=Severity.MODERATE,
    allow=["heck"],
    block=["internal-ban-word"],
)

result = shield.check("clean this text")
print(result.to_dict())

Options

filter_text() and ProfanityFilter() accept:

• languages: a language name or iterable. Bundled data includes english, spanish, german, and french.
• all_languages: use every bundled language dictionary.
• allow: words that should never be flagged.
• block: extra words that should always be flagged.
• mask: a replacement character or callback (word, length) -> str.
• minimum_severity: mild, moderate, high, or extreme.

Result Shape

{
    "original": "This is shit",
    "clean": "This is ****",
    "is_offensive": True,
    "score": 40,
    "count": 1,
    "unique_words": ["shit"],
    "severity": "high",
    "words": [
        {
            "text": "shit",
            "base": "shit",
            "severity": "high",
            "position": 8,
            "length": 4,
            "language": "english",
        }
    ],
}

Scope

This fork intentionally ports the profanity filter itself, not Blasp's Laravel service provider, middleware, Eloquent helpers, events, facades, or cache layer.

Upstream Sync

Use scripts/sync_from_blasp.py to fetch the latest Blasp PHP repository, export updated dictionary/config data into Profy's Python package, and generate an implementation-change report for PHP files that need manual port review.

python scripts/sync_from_blasp.py

Release

Alpha releases use PEP 440 versions such as 0.1.0a1 and Git tags such as v0.1.0a1. The GitHub Actions release workflow runs tests, builds the source distribution and wheel, uploads them as artifacts, and attaches them to the GitHub Release.
