# :link: Autolink [![Build Status](https://travis-ci.org/hugoabonizio/autolink.cr.svg?branch=master)](https://travis-ci.org/hugoabonizio/autolink.cr)

*Autolink.cr* is a Crystal shard that automatically turns URLs into links.

Example:

```crystal
auto_link("Welcome to my profile https://github.com/hugoabonizio")
# => Welcome to my profile <a href="https://github.com/hugoabonizio">https://github.com/hugoabonizio</a>
```

## Installation

Add this to your application's `shard.yml`:

```yaml
dependencies:
  autolink:
    github: hugoabonizio/autolink.cr
```

## Usage

```crystal
require "autolink"

include Autolink

auto_link("My blog: http://www.myblog.com/", html: {"class" => "menu", "target" => "_blank"})
# => My blog: <a href=\"http://www.myblog.com/\" class=\"menu\" target=\"_blank\">http://www.myblog.com/</a>
```

### Simple autolink

Without providing any HTML options *autolink.cr* will just wrap the URL with ```<a>``` tag.

```crystal
Autolink.auto_link("Welcome to my new blog at http://www.myblog.com/")
# => Welcome to my new blog at <a href="http://www.myblog.com/">http://www.myblog.com/</a>
```

### Custom tag attributes

The ```<a>``` tag can receive custom attributes.

```crystal
Autolink.auto_link("My blog: http://www.myblog.com/", html: {"class" => "menu", "target" => "_blank"})
# => My blog: <a href=\"http://www.myblog.com/\" class=\"menu\" target=\"_blank\">http://
```
