[![Build Status](https://travis-ci.org/what3words/w3w-ruby-wrapper.svg?branch=master)](https://travis-ci.org/what3words/w3w-ruby-wrapper)

The Ruby wrapper is useful for Ruby developers who wish to seamlessly integrate the [what3words Public API](https://developer.what3words.com/public-api) into their Ruby applications, without the hassle of having to manage the low level API calls themselves.

The what3words API is a fast, simple interface which allows you to convert what3words addresses such as `///index.home.raft` to latitude and longitude coordinates such as `-0.203586, 51.521251` and vice versa. It features a powerful autosuggest function, which can validate and autocorrect user input and limit it to certain geographic areas (this powers the search box on our map site). It allows you to request a section of the what3words grid (which can be requested as GeoJSON for easy display on online maps), and to request the list of all languages supported by what3words. For advanced users, autosuggest can be used to post-process voice output.

All coordinates are latitude,longitude pairs in standard `WGS-84` (as commonly used worldwide in GPS systems). All latitudes must be in the range of `-90 to 90 (inclusive)`.

## Installation

The library is available through [RubyGems](https://rubygems.org/gems/what3words).

You can simply add this line to your application's Gemfile:

```
    gem 'what3words', '~> 3.4'
```

And then execute:

```shell
    $ bundle
```

Or install it yourself as:

```shell
    $ gem install what3words
```

## Usage

Sign up for an API key at [https://developer.what3words.com](https://developer.what3words.com)

See [https://developer.what3words.com/public-api/docs](https://developer.what3words.com/public-api/docs) for all parameters that can be passed to the API calls.

If not using Bundler, require it:

```ruby
    require 'what3words'
```

Then:

```ruby
    what3words = What3Words::API.new(:key => "YOURAPIKEY")
```

Convert to Coordinates: convert a what3words address into GPS coordinates (WGS84)

```ruby
what3words.convert_to_coordinates 'prom.cape.pump'
```

**Expected Output**
```
# => {:country=>"GB", :square=>{:southwest=>{:lng=>-0.195426, :lat=>51.484449}, :northeast=>{:lng=>-0.195383, :lat=>51.484476}}, :nearestPlace=>"Kensington, London", :coordinates=>{:lng=>-0.195405, :lat=>51.484463}, :words=>"prom.cape.pump", :language=>"en", :map=>"https://w3w.co/prom.cape.pump"}
```

## API
### Convert to Coordinates

what3words.convert_to_3wa [29.567041, 106.587875]
```

**Expected Output**
```
# => {:country=>"CN", :square=>{:southwest=>{:lng=>106.58786, :lat=>29.567028}, :northeast=>{:lng=>106.587891, :lat=>29.567055}}, :nearestPlace=>"Chongqing", :coordinates=>{:lng=>106.587875, :lat=>29.567041}, :words=>"disclose.strain.redefined", :language=>"en", :map=>"https://w3w.co/disclose.strain.redefined"}
```

Convert position information to a what3words address in a specific language

```ruby
what3words.convert_to_3wa [29.567041, 106.587875], language: 'fr'
```

**Expected Output**
```
# => :country=>"CN", :square=>{:southwest=>{:lng=>106.58786, :lat=>29.567028}, :northeast=>{:lng=>106.587891, :lat=>29.567055}}, :nearestPlace=>"Chongqing", :coordinates=>{:lng=>106.587875, :lat=>29.567041}, :words=>"courgette.rabotons.infrason", :language=>"fr", :map=>"https://w3w.co/courgette.rabotons.infrason"}
```

Supported keyword params for `convert_to_3wa` call:

* `coordinates` The coordinates of the location to convert to what3words address
* `language` (defaults to en) - A supported what3words address language as an ISO 639-1 2 letter code
* `format` Return data format type. It can be one of json (the default) or geojson

### Autosuggest
Returns a list of what3words addresses based on user input and other parameters.

This resource provides corrections for the following types of input error:
- typing errors
- spelling errors
- misremembered words (e.g. singular vs. plural)
- words in the wrong order

The autosuggest resource determines possible corrections to the supplied what3words address string based on the probability of the input errors listed above and returns a ranked list of suggestions. This resource can also take into consideration the geographic proximity of possible corrections to a given location to further improve the suggestions returned.

See [https://developer.what3words.com/public-api/docs#autosuggest](https://developer.what3words.com/public-api/docs#autosuggest) for detailed information

Supported keyword params for `autosuggest` call:
  * `input` The full or partial what3words address to obtain suggestions for. At minimum this must be the first two complete words plus at least one character from the third word.
  * `language` A supported what3words address language as an ISO 639-1 2 letter code. This setting is on by default. Use false to disable this setting and receive more suggestions in the sea.
  * `n_results` The number of AutoSuggest results to return. A maximum of 100 results can be specified, if a number greater than this is requested, this will be truncated to the maximum. The default is 3.
  * `n_focus_results` Specifies the number of results (must be <= n_results) within the results set which will have a focus. Defaults to n_results. This allows you to run autosuggest with a mix of focussed and unfocussed results, to give you a "blend" of the two.
  * `clip-to-country` Restricts autosuggest to only return results inside the countries specified by comma-separated list of uppercase ISO 3166-1 alpha-2 country codes (for example, to restrict to Belgium and the UK, use clip_to_country="GB,BE").
  * `clip-to-bounding-box` Restrict autosuggest results to a bounding box, specified by coordinates.
  * `clip-to-circle` Restrict autosuggest results to a circle, specified by the center of the circle, latitude and longitude, and a distance in kilometres which represents the radius. For convenience, longitude is allowed to wrap around 180 degrees. For example 181 is equivalent to -179.
  * `clip-to-polygon` Restrict autosuggest results to a polygon, specified by a list of coordinates. The polygon should be closed, i.e. the first element should be repeated as the last element; also the list should contain at least 4 entries. The API is currently limited to accepting up to 25 pairs.
  * `input-type` For power users, used to specify voice input mode. Can be text (default), vocon-hybrid, nmdp-asr or generic-voice.
  * `prefer-land` Makes autosuggest prefer results on land to those in the sea.

### Grid
Returns a section of the 3m x 3m what3words grid for a given area.

See [https://developer.what3words.com/public-api/docs#grid-section](https://developer.what3words.com/public-api/docs#grid-section) for detailed information.

Gets grid for these bounding box northeast 52.208867,0.117540,52.207988,0.116126.

```ruby
what3words.grid_section '52.208867,0.117540,52.207988,0.116126'
```

**Expected Output**
```
# => {:lines=>[{:start=>{:lng=>0.116126, :lat=>52.20801}, :end=>{:lng=>0.11754, :lat=>52.20801}}, {:start=>{:lng=>0.116126, :lat=>52.208037}, :end=>{:lng=>0.11754, :lat=>52.208037}}, {:start=>{:lng=>0.116126, :lat=>52.208064}, :end=>{:lng=>0.11754, :lat=>52.208064}}, ___...___ ]}
```

Supported keyword params for `grid_section` call:
  * `bounding-box` The bounding box is specified by the northeast and southwest corner coordinates, for which the grid should be returned
  * `format` Return data format type. It can be one of json (the default) or geojson

```ruby
what3words.available_languages
```

**Expected Output**
```
# => {:languages=>[{:nativeName=>"Deutsch", :code=>"de", :name=>"German"}, {:nativeName=>"हिन्दी", :code=>"hi", :name=>"Hindi"}, {:nativeName=>"Português", :code=>"pt", :name=>"Portuguese"}, {:nativeName=>"Magyar", :code=>"hu", :name=>"Hungarian"}, {:nativeName=>"Українська", :code=>"uk", :name=>"Ukrainian"}, {:nativeName=>"Bahasa Indonesia", :code=>"id", :name=>"Bahasa Indonesia"}, {:nativeName=>"اردو", :code=>"ur", :name=>"Urdu"}, ___...___]}
```

See [https://developer.what3words.com/public-api/docs#available-languages](https://developer.what3words.com/public-api/docs#available-languages) for the original API call documentation.

### RegEx functions

This section introduces RegEx functions that can assist with checking and finding possible what3words addresses in strings. The three main functions covered are:

`isPossible3wa` – Match what3words address format;
    `findPossible3wa` – Find what3words address in Text;
    `isValid3wa` – Verify a what3words address with the API;

#### isPossible3wa

Our API wrapper RegEx function `isPossible3wa` can be used used to detect if a text string (like `filled.count.soap`) in the format of a what3words address without having to ask the API. This functionality checks if a given string could be a what3words address. It returns true if it could be, otherwise false.

**Note**: This function checks the text format but not the validity of a what3words address. Use `isValid3wa` to verify validity.

```ruby
require 'what3words'

def main
  # Initialize the What3Words API with your API key
  api_key = 'YOUR_API_KEY'
  w3w = What3Words::API.new(:key => api_key)

# Example what3words addresses
  addresses = ["filled.count.soap", "not a 3wa", "not.3wa address"]

# Check if the addresses are possible what3words addresses
  addresses.each do |address|
    is_possible = w3w.isPossible3wa(address)
    puts "Is '#{address}' a possible what3words address? #{is_possible}"
  end
end

if __FILE__ == $0
  main
end
```

**Expected Output**

isPossible3wa(“filled.count.soap”) returns true
    isPossible3wa(“not a 3wa”) returns false
    isPossible3wa(“not.3wa address”)returns false

#### findPossible3wa

Our API wrapper RegEx function `findPossible3wa` can be used to detect a what3words address within a block of text, useful for finding a what3words address in fields like Delivery Notes. For example, it can locate a what3words address in a note like “Leave at my front door ///filled.count.soap”. The function will match if there is a what3words address within the text. If no possible addresses are found, it returns an empty list.

**Note**:

- This function checks the text format but not the validity of a what3words address. Use `isValid3wa` to verify validity.
- This function is designed to work across languages but do not work for `Vietnamese (VI)` due to spaces within words.

```ruby
require 'what3words'

def main
  # Initialize the what3words API with your API key
  api_key = 'YOUR_API_KEY'
  w3w = What3Words::API.new(:key => api_key)

# Example texts
  texts = [
    "Please leave by my porch at filled.count.soap",
    "Please leave by my porch at filled.count.soap or deed.tulip.judge",
    "Please leave by my porch at"
  ]

# Check if the texts contain possible what3words addresses
  texts.each do |text|
    possible_addresses = w3w.findPossible3wa(text)
    puts "Possible what3words addresses in '#{text}': #{possible_addresses}"
  end
end

if __FILE__ == $0
  main
end
```

**Expected Output**

findPossible3wa(“Please leave by my porch at filled.count.soap”) returns ['filled.count.soap']
    findPossible3wa(“Please leave by my porch at filled.count.soap or deed.tulip.judge”) returns ['filled.count.soap', 'deed.tulip.judge']
    findPossible3wa(“Please leave by my porch at”) returns []

#### isValid3wa

Our API wrapper RegEx function `isValid3wa` can be used to determine if a string is a valid what3words address by checking it against the what3words RegEx filter and verifying it with the what3words API.

```ruby
require 'what3words'

def main
  # Initialize the what3words API with your API key
  api_key = 'YOUR_API_KEY'
  w3w = What3Words::API.new(:key => api_key)

# Example addresses
  addresses = [
    "filled.count.soap",
    "filled.count.",
    "coding.is.cool"
  ]

# Check if the addresses are valid what3words addresses
  addresses.each do |address|
    is_valid = w3w.isValid3wa(address)
    puts "Is '#{address}' a valid what3words address? #{is_valid}"
  end
end

if __FILE__ == $0
  main
end
```
**Expected Outputs**

isValid3wa(“filled.count.soap”) returns True
    isValid3wa(“filled.count.”) returns False
    isValid3wa(“coding.is.cool”) returns False

Also make sure to replace `<YOUR_API_KEY>` with your actual API key. These functionalities provide different levels of validation for what3words addresses, from simply identifying potential addresses to verifying their existence on Earth.
