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`:
```elixir
def deps do
[{:auto_linker, "~> 0.2"}]
[{:linkify, "~> 0.1"}]
end

The following examples illustrate some examples on how to use the auto linker.
```iex
iex> AutoLinker.link("google.com")
"<a href='http://google.com' class='auto-linker' target='_blank' rel='noopener noreferrer'>google.com</a>"
iex> AutoLinker.link("google.com", new_window: false, rel: false)
"<a href='http://google.com' class='auto-linker'>google.com</a>"
iex> AutoLinker.link("google.com", new_window: false, rel: false, class: false)
"<a href='http://google.com'>google.com</a>"
iex> AutoLinker.link("call me at x9999", phone: true)
"call me at <a href=\"#\" class=\"phone-number\" data-phone=\"9999\">x9999</a>"
iex> AutoLinker.link("or at home on 555.555.5555", phone: true)
"or at home on <a href=\"#\" class=\"phone-number\" data-phone=\"5555555555\">555.555.5555</a>"
iex> AutoLinker.link(", work (555) 555-5555", phone: true)
", work <a href=\"#\" class=\"phone-number\" data-phone=\"5555555555\">(555) 555-5555</a>"
iex> AutoLinker.link("[Google Search](http://google.com)", markdown: true)
"<a href='http://google.com' class='auto-linker' target='_blank' rel='noopener noreferrer'>Google Search</a>"
```
See the [Docs](https://hexdocs.pm/auto_linker/) for more examples
## Configuration
By default, link parsing is enabled and phone parsing is disabled.
```elixir
# enable phone parsing, and disable link parsing
config :auto_linker, opts: [phone: true, url: false]
iex> Linkify.link("google.com")
"<a href=\"http://google.com\">google.com</a>"
iex> Linkify.link("google.com", class: "linkified")
"<a href=\"http://google.com\" class=\"linkified\">google.com</a>"
iex> Linkify.link("google.com", new_window: true)
"<a href=\"http://google.com\" target=\"_blank\">google.com</a>"
iex> Linkify.link("google.com", new_window: true, rel: "noopener noreferrer")
"<a href=\"http://google.com\" target=\"_blank\" rel=\"noopener noreferrer\">google.com</a>"
```

* `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 `..`
