What is the best way to get the name of all indexes?

I am currently using _cat/indices and parsing the return of that.. But I wondered if there's a nicer api method that will just return an array of index names?

With /_cat/indices you can add a format parameter to get the results back in either YAML or JSON format:

GET _cat/indices?format=json


GET _cat/indices?format=yaml

A structured result like that might be easier for you to parse automatically?
