Format and lint Python code blocks within Markdown files. Usable as CLI, 
`pre-commit` hook or Python package.

`md-snakeoil` is built on the awesome [`ruff`](https://docs.astral.sh/ruff/)
formatter and linter and helps you to keep your Markdown files looking 
sharp. 🤙🏽

## Quickstart

With [`uv`](https://docs.astral.sh/uv/getting-started/installation/) install 
it as a tool:

```bash
uv tool install md-snakeoil
```

Format and lint Markdown files within a directory (recursively):

```bash
snakeoil path/to/directory
```

That's it! 🚀

> [!NOTE]
> If, your using [`pipx`](https://pipx.pypa.io/stable/installation/), 
> install it with `pipx install md-snakeoil`

## `pre-commit` hook

To run `md-snakeoil` with `pre-commit` add following to your 
`.pre-commit-config.yaml`:

```yaml
repos:
  - repo: https://github.com/JakobKlotz/md-snakeoil
    rev: v0.1.7
    hooks:
      - id: snakeoil
```

## Command Line Interface

The package provides a command-line interface (CLI) using `typer`.

### Help

```bash
snakeoil --help
```

```

```

By default, the line length is set to 79 characters, and the Ruff rules `W` and
`I` are enabled. You can change these defaults using the `--line-length` and
`--rules` options.

### Single Markdown

```bash
snakeoil path/to/file.md
```

### Formatting all files in a directory

```bash
snakeoil path/to/directory
```

This will recursively format and lint the Python code blocks in all Markdown
files within `path/to/directory`. 

For example, format the example files within the `tests/` directory 
(of this repository):

```bash
snakeoil tests/examples
```

```bash
