AutoLinker is a basic package for turning website names, and phone numbers into links.
Linkify is a basic package for turning website names into links.
Use this package in your web view to convert web references into click-able links.
This is a very early version. Some of the described options are not yet functional.
## Installation
The package can be installed by adding `auto_linker` to your list of dependencies in `mix.exs`:
The package can be installed by adding `linkify` to your list of dependencies in `mix.exs`:

The following examples illustrate some examples on how to use the auto linker.
```iex

See the [Docs](https://hexdocs.pm/auto_linker/) for more examples
## Configuration
By default, link parsing is enabled and phone parsing is disabled.
See the [Docs](https://hexdocs.pm/linkify/) for more examples
```elixir
# enable phone parsing, and disable link parsing
config :auto_linker, opts: [phone: true, url: false]
```

* `new_window: true` - set to false to remove `target='_blank'` attribute
* `scheme: false` - Set to true to link urls with schema `http://google`
* `truncate: false` - Set to a number to truncate urls longer then the number. Truncated urls will end in `..`
* `strip_prefix: true` - Strip the scheme prefix
* `exclude_class: false` - Set to a class name when you don't want urls auto linked in the html of the give class
* `exclude_id: false` - Set to an element id when you don't want urls auto linked in the html of the give element
* `exclude_patterns: ["```"]` - Don't link anything between the the pattern
* `markdown: false` - link markdown style links
* `email: false` - link email links

* `mention_prefix: nil` - a prefix to build a link for a mention (example: `https://example.com/user/`)
