# Ruby Reducers
If any additional arguments was passed, **fx** converts it to a function which
takes the JSON as an argument named `x`.
```sh
export FX_LANG=ruby
```
Example:
```sh
fx data.json 'x.to_a.map {|x| x[1]}'
```
## Dot
Fx supports simple syntax for accessing data, which can be used with any `FX_LANG`.
```sh
$ echo '{"foo": [{"bar": "value"}]}' | fx .foo[0].bar
value
```
