#### `urlParse`

Parses a string as a URL for later use. Equivalent to [url.Parse](https://golang.org/pkg/net/url/#Parse)

##### Example

_`input.tmpl`:_
```
{{ $u := urlParse "https://example.com:443/foo/bar" }}
The scheme is {{ $u.Scheme }}
The host is {{ $u.Host }}
The path is {{ $u.Path }}
```

```console
$ gomplate < input.tmpl
The scheme is https
The host is example.com:443
The path is /foo/bar
```

#### `has`

Has reports whether or not a given object has a property with the given key. Can be used with `if` to prevent the template from trying to access a non-existent property in an object.
