# Readability
[](https://github.com/MarkHarper/readability/actions/workflows/elixir.yml)
[](https://hex.pm/packages/readability2)
Readability2 is a tool for extracting and curating the primary readable content of a webpage. It's primarily a fork of [readability](https://github.com/keepcosmos/readability) with more up to date dependencies.
Check out The [Documentation](https://hexdocs.pm/readability2/Readability.html) for full and detailed guides
## Installation
If [available in Hex](https://hex.pm/docs/publish), the package can be installed as:
1. Add readability to your list of dependencies in `mix.exs`:
```elixir
def deps do
[{:readability2, "~> 0.4"}]
end
```
2. Ensure readability is started before your application:
```elixir
def application do
[applications: [:readability2]]
end
```
Note: Readability requires Elixir 1.3 or higher.
## Usage
### Examples
#### Just pass a url
```elixir
url = "https://medium.com/@kenmazaika/why-im-betting-on-elixir-7c8f847b58"
summary = Readability.summarize(url)
summary.title
#=> "Why I’m betting on Elixir"
summary.authors
#=> ["Ken Mazaika"]
summary.article_html
#=>
# <div><div><p id=\"3476\"><strong><em>Background: </em></strong><em>I’ve spent...
# ...
# ...button!</em></h3></div></div>
summary.article_text
#=>
# Background: I’ve spent the past 6 years building web applications in Ruby and.....
# ...
# ... value in this article, it would mean a lot to me if you hit the recommend button!
```
#### From raw html
```elixir
### Extract the title.
Readability.title(html)
### Extract authors.
Readability.authors(html)
### Extract the primary content with transformed html.
html
|> Readability.article
|> Readability.readable_html
### Extract only text from the primary content.
html
|> Readability.article
|> Readability.readable_text
### you can extract the primary images with Floki
html
|> Readability.article
|> Floki.find("img")
|> Floki.attribute("src")
```

#### Example
```elixir
url = "https://medium.com/@kenmazaika/why-im-betting-on-elixir-7c8f847b58"
summary = Readability.summarize(url, [clean_conditionally: false])
```
* min_text_length \\\\ 25
* remove_unlikely_candidates \\\\ true
* weight_classes \\\\ true
* clean_conditionally \\\\ true
* retry_length \\\\ 250
**You can find other algorithm and regex options in `readability.ex`**
