Flake8 plugin that detects and reports any emoji characters in Python source code. Helps keep your codebase clean, consistent, and free from unwanted Unicode emojis.

---

Features

Note: Do not set the same category in both --ignore-emoji-types and --only-emoji-types, as only takes precedence over ignore.

• Scans Python files for all Unicode emoji characters (including multi-codepoint clusters).

• Raises a linting error (EMO001) when emojis are found.

• Supports filtering by emoji categories:

  • --ignore-emoji-types=PEOPLE,FOOD
  • --only-emoji-types=FLAGS

• Works seamlessly with Flake8 and pre-commit hooks.

• Lightweight and dependency-minimal (regex and emoji required).

---

Installation

pip install flake8-no-emoji

---

Usage

Run normally via flake8:

flake8 app

flake8 --select=EMO

Example output:

/example.py:3:10: EMO001 Emoji detected in code

---

Configuration

You can configure categories to ignore or allow exclusively.

Ignore certain categories

flake8 --ignore-emoji-types=PEOPLE,FOOD

This ignores emojis in the PEOPLE and FOOD categories, but still reports others.

Allow only specific categories

flake8 --only-emoji-types=FLAGS

This only reports FLAGS emojis, ignoring everything else. (Note: only takes precedence over ignore.)
