# Elixirize

This adds the `ᐅ` method to Ruby.  It pipes in the returned value of the left as the first parameter of the
Proc _(or anything with `:call` defined)_ on the right.

### Unicode ᐅ

To enter ᐅ you need to:

* **Linux:** type **CTRl-SHIFT-U** and then **1405** followed by the **Space** or **Enter** key.
* **Mac:**  hold the **Option** key while you type **1405** and then release the **Option** key.
* **VIM:** press **CTRL-v** then **SHIFT-U** then **1405** and hit **Enter**.
* **Emacs:** press **CTRL-x** then **8** then **Enter** and type **1405** and hit **Enter**.

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'elixirize'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install elixirize

## Usage

```ruby
def add a, b
  a + b
end

subtract = ->a, b{ a - b }

add(4, 5).ᐅ subtract, 15
# => -6

def divide a, b
  a / b
end

add(40, 60).ᐅ method(:divide), 20
# => 5
```

## Extra

Since Ruby is designed largely to call methods on the object that was returned
I've written the `~` method on `Symbol` to allow method calls on the returned
object rather than only being the first parameter passed in.

**Example:**

```ruby
s = "a b c d"
val = s.
  ᐅ(~:split, " ").
  ᐅ(~:join, "-").
  ᐅ ~:capitalize

val
# => "A-b-c-d"
```

You can mix both behaviors without any issue.

This may seem counter intuitive as it's the same thing as just calling the method
on the object, but consider this a noticeable refactoring step.  If you're designing
a project in a manner where you want results piped in as the first parameter then
the tilde-symbol will be your TODO reminder to convert/refactor how your code base is
implemented.

## Development

After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake test` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
