# ============================================================
# VARIANT: se-codeowners
# Updated: 2026-06-01

# Fast, consistent repo hygiene before commit.
#
# These hooks complement and do not replace:
# - .editorconfig
# - .gitattributes
# - pyproject.toml
#
# Local usage:
#   uv self update
#   uvx pre-commit install
#   uvx pre-commit run --all-files
#
# Ruff lint runs before Ruff format in pre-commit so autofixes
# are formatted in the same pass.

  # === REPO: PRE-COMMIT HOOKS (cross-platform, zero config) ===
  #
  # These hooks prevent problems that show up later as:
  #   - mysterious diffs
  #   - broken builds on another OS

  - repo: https://github.com/pre-commit/pre-commit-hooks
    rev: v6.0.0

      # === PRE-COMMIT: CHECK FOR COMMON PROBLEMS ===

      - id: check-added-large-files
        name: C1) Prevent accidental commits of large binaries
        args: [--maxkb=2000] # WHY: 2MB is a common threshold for large files

        name: C2) Prevent committing merge conflicts

      - id: check-case-conflict
        name: C3) Check for filename case conflicts

  # === REPO: RUFF PRE-COMMIT (for Python code) ===

  - repo: https://github.com/astral-sh/ruff-pre-commit
    rev: v0.15.12
    hooks:
      - id: ruff-check
        name: D1) Ruff linter with autofix (runs first in pre-commit)
        # WHY: Lint fixes run first so formatter sees the corrected code.
        args: [--fix, --exit-non-zero-on-fix]

      - id: ruff-format
        name: D2) Ruff formatter (runs after linter fixes)
