# Setu - CLI Markdown Link Checker

`setu` scans your documentation, extracts links, and validates both local file paths and remote URLs concurrently so your docs never suffer from bit rot or broken pathways.

### Motivation
After working on countless projects that all use markdown I find myself running into the same issue, are all my links valid?
A simple typo could redirect users to a dead website or a missing asset and these issues are often caught too late; in production.


## Installation:

Using cargo:

```shell
cargo install setu-cli
```

## Usage:

```
Usage: setu-cli [OPTIONS] [TARGET_PATH]

Arguments:
  [TARGET_PATH]  [default: .]

Options:
  -s, --strict
  -h, --help     Print help
  -V, --version  Print version
```

## Examples:
Use setu to scan the current directory in strict mode
```shell
setu-cli -s
```

To scan a different directory type its path:
```shell
setu-cli ./docs
```

### Concerns Argument

Setu treats remote URL's as OK if _something_ is returned from them, even if thats a `404`, because the site is still _reachable_.
You can flag specific response codes as concerns using the `--concerns` argument: 

```shell
setu-cli --concerns 404,500
```

For example under these rules:

`404 - Faulty`

`401 - Valid`

`500 - Faulty`

## CI Examples

To use this as part of your CI see [the workflow used by this repository](https://github.com/tom-devv/Setu/blob/main/.github/workflows/markdown-checker.yml).

When running `setu-cli` as part of your CI, you should run it in `--strict` mode to terminate the program with exit code 1.
