-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
```
## Usage
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>"
+```elixir
-iex> AutoLinker.link("call me at x9999", phone: true)
-"call me at <a href=\"#\" class=\"phone-number\" data-phone=\"9999\">x9999</a>"
+iex> Linkify.link("google.com")
+"<a href=\"http://google.com\">google.com</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> Linkify.link("google.com", class: "linkified")
+"<a href=\"http://google.com\" class=\"linkified\">google.com</a>"
-iex> AutoLinker.link(", work (555) 555-5555", phone: true)
-", work <a href=\"#\" class=\"phone-number\" data-phone=\"5555555555\">(555) 555-5555</a>"
+iex> Linkify.link("google.com", new_window: true)
+"<a href=\"http://google.com\" target=\"_blank\">google.com</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>"
+iex> Linkify.link("google.com", new_window: true, rel: "noopener noreferrer")
+"<a href=\"http://google.com\" target=\"_blank\" rel=\"noopener noreferrer\">google.com</a>"
```
-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]
-```
