The Non-Destructive Configuration Steward for Python Projects.

ApexCodexPy

The Non-Destructive Configuration Steward for Python Projects.

ApexCodexPy is a CLI tool designed to enforce consistent linting and typing standards across multiple projects. Unlike standard runners, ApexCodexPy synchronizes your pyproject.toml with a "Gold Standard" configuration without destroying existing project-specific settings or comments.

🚀 Purpose

Modern Python development often suffers from "Config Drift"—where different projects slowly diverge in their ruff or mypy settings. ApexCodexPy solves this by:

Enforcing Standards

Overwriting critical linting rules with a centralized set of best practices.

Preserving Context

Using tomlkit to ensure that your handwritten comments and formatting remain intact.

Dry-Run Capability

Allowing developers to see exactly what would change before any modifications are written to disk.

📦 Installation & Integration

From PyPI

Since ApexCodexPy is available on PyPI, you can add it directly to your project using Poetry:

poetry add apexcodexpy --group dev

🛠 Usage

1. Synchronize Configuration

Align your pyproject.toml with the ApexCodexPy standards.

# Preview changes (Dry Run)
codex update --dry-run

# Apply changes
codex update

2. Run Linting & Formatting checks

Run the enforced toolchain (Ruff and Mypy) on your project.

# Standard run (verbose)
codex lint

# No output (suppress stdout/stderr)
codex lint --silent

3. Auto formating and fixing

Run the enforced toolchain (Ruff and Mypy) on your project.

# Standard run (verbose)
codex fix

# No output (suppress stdout/stderr)
codex fix --silent

🧩 Standards Enforced

ApexCodexPy currently enforces a strict ruff.lint.select list including:

Name	Code
pyflakes	F
pycodestyle (Errors)	E
pycodestyle (Warnings)	W
isort	I
pep8-naming	N
pyupgrade	UP
flake8-bugbear	B
flake8-builtins	A
flake8-comprehensions	C4
flake8-print	T20
flake8-pytest-style	PT
flake8-raise	RSE
flake8-return	RET
flake8-simplify	SIM
flake8-unused-arguments	ARG

It also enforces mypy.strict = true.

👨‍💻 For Developers: How it Works

Non-Destructive Merge

The core logic resides in a functional deep_merge. It takes the project's current TOML and the ApexCodexPy standards, returns a new configuration, and preserves all tomlkit item metadata (inline comments).

Architecture: Strategy Pattern

• Task Protocol: implementations run various tools and report their results.
• Device Protocol: used by reporter to output results.
• Reporter: standard output format.
• PyCodex: Class that ties everything together.

To add a new tool:

• Create a new Task implementation.
• Add the tool's standard config to get_standards().
• Register the task in PyCodex.
• Add CLI command using the above-mentioned PyCodex method.
