EPITA C Coding Style Checker - validates C code against EPITA coding standards

EPITA C Coding Style Checker

A fast C linter for EPITA coding style rules. Uses tree-sitter for robust AST-based parsing.

Installation

pipx install epita-coding-style

Quick Start

epita-coding-style src/           # Check files/directories
epita-coding-style --list-rules   # List all rules with descriptions
epita-coding-style --show-config  # Show current configuration
epita-coding-style --help         # Full usage info

Configuration

Configuration is auto-detected from (in order):

• .epita-style
• .epita-style.toml
• epita-style.toml
• [tool.epita-coding-style] in pyproject.toml

Priority: CLI flags > config file > preset > defaults

Generate a Config File

epita-coding-style --show-config --no-color > .epita-style.toml

This outputs a complete, commented TOML config you can customize.

Presets

epita-coding-style --preset 42sh src/      # 40 lines, goto/cast allowed
epita-coding-style --preset noformat src/  # Same + skip clang-format

Example Config

# .epita-style.toml
max_lines = 40

[rules]
"keyword.goto" = false  # Allow goto
"cast" = false          # Allow casts

Or in pyproject.toml:

[tool.epita-coding-style]
max_lines = 40

[tool.epita-coding-style.rules]
"keyword.goto" = false

clang-format

The format rule uses clang-format to check code formatting. Requires clang-format to be installed.

The checker looks for .clang-format in the file's directory (walking up to root), or uses the bundled EPITA config.

To disable: set "format" = false in your config, or use --preset noformat.
