## Installation
If [available in Hex](https://hex.pm/docs/publish), the package can be installed as:
1. Add phoenix_html_simplified_helpers to your list of dependencies in `mix.exs`:
```elixir
def deps do
[{:phoenix_html_simplified_helpers, "~> x.x.x"}]
end
```
2. Ensure phoenix_html_simplified_helpers is started before your application:
```elixir
def application do
[applications: [:phoenix_html_simplified_helpers]]
end
```
3. phoenix_html_simplified_helpers need to import(use) your Phoenix project. The following description is adding 'use syntax' into web.ex.
```elixir
def view do
quote do
use Phoenix.View, root: "web/templates"
# Import convenience functions from controllers
import Phoenix.Controller, only: [get_csrf_token: 0, get_flash: 2, view_module: 1]
# Use all HTML functionality (forms, tags, etc)
use Phoenix.HTML
use Phoenix.HTML.SimplifiedHelpers # <- this line.
import MyApp.Router.Helpers
import MyApp.ErrorHelpers
import MyApp.Gettext
end
end
```
Also it is able to import(use) in each view helper files.
```elixir
defmodule MyApp.LayoutView do
use MyApp.Web, :view
import Phoenix.HTML.SimplifiedHelpers.Truncate # <- this line.
import Phoenix.HTML.SimplifiedHelpers.TimeAgoInWords # <- this line.
end
```
4. time_ago_in_words has Gettext module that is changed translation file from project's locale.
```elixir
Gettext.put_locale(Phoenix.HTML.SimplifiedHelpers.Gettext, "en")
Gettext.put_locale(Phoenix.HTML.SimplifiedHelpers.Gettext, "ja")
Gettext.put_locale(Phoenix.HTML.SimplifiedHelpers.Gettext, "es")
```

# And they f... (continued)
```
## time_ago_in_words
```elixir
<%= time_ago_in_words entity.published_at %> ago
```
```elixir
time_ago_in_words Timex.Date.now
# less than 5 seconds
time_ago_in_words Timex.Date.now(:secs)
# less than 5 seconds
time_ago_in_words Ecto.DateTime.utc
# less than 5 seconds
```
### distance_of_time_in_words
```elixir
from = Timex.Date.from({{2015, 10, 31}, {0, 0, 0}})
to = Timex.Date.shift(from, days: 45)
distance_of_time_in_words(from, to)
# about 2 months
Gettext.put_locale(Phoenix.HTML.SimplifiedHelpers.Gettext, "ja")
from = Timex.Date.from({{2015, 10, 31}, {0, 0, 0}})
to = Timex.Date.shift(from, months: 1)
distance_of_time_in_words(from, to)
# 約1ヶ月
Gettext.put_locale(Phoenix.HTML.SimplifiedHelpers.Gettext, "es")
from = Timex.Date.from({{2015, 10, 31}, {0, 0, 0}})
to = Timex.Date.shift(from, months: 18)
distance_of_time_in_words(from, to)
# más de 1 año
