[back to package description]

Welcome to aeson-pretty

This is a JSON pretty-printing Haskell library compatible with aeson as well as a command-line tool to improve readabilty of streams of JSON data.

The library provides a single function encodePretty. It is a drop-in replacement for aeson's encode function, producing JSON-ByteStrings for human readers.

The command-line tool reads JSON from stdin and writes prettified JSON to stdout. It also offers a complementary "compact"-mode, essentially the opposite of pretty-printing.
