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]}'
|
||
|
|
```
|
||
|
|
|

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
|
||
|
|
```
