# mdlink

`mdlink` is a CLI tool to recursively scan Markdown files and validate HTTP/HTTPS links.

## Features

- Scans `.md` files recursively in a directory (or a single `.md` file).
- Extracts Markdown links (`[text](url)`) and naked URLs (`https://...`).
- Ignores image links (`![alt](url)`).
- Checks links with `httpx` and follows redirects automatically.
- Ignores `200 OK` in the report; shows non-200 and request errors.
- Shows final resolved URL in output.
- Asks interactively before rewriting redirected Markdown links.
- Re-checks target URL before writing (must still return `200`).
- Rewrites links via Markdown AST editing (`markdown-it-py`), not string replacement.

## Installation

```bash
python3 -m venv .venv
source .venv/bin/activate
pip install .
```

## Usage

```bash
mdlink /path/to/docs
```

## Options

- `--timeout FLOAT`  
  Per-request timeout in seconds (default: `10.0`).

## Interactive Redirect Rewrite

When a Markdown link redirects, `mdlink` prompts:

```text
Replace old URL with final URL? [y/N]
```

- [broken](https://httpbin.org/status/404)

Only confirmed links are updated.
