Programmatically add field formatting using ES mappings on the .kibana index

I absolutely love the idea of turning certain fields into clickable links, etc.

I would however like to do this programmatically.

This is already possible, you can simply modify the formatter for the field in the index pattern, which is stored in elasticsearch. Feel free to grab a snapshot build, create a formatted field, and inspect the indexpattern is belongs to, everything is stored in the .kibana index.
