vj

vj is a command‑line utility that formats JSON data into a more readable layout. It can be installed via the Ruby package manager and invoked to pipe raw JSON streams through a formatter that adds indentation and optional field selection. The tool is useful for developers who need to inspect or debug JSON output from network services or APIs without writing custom pretty‑printing code.

Typical usage involves connecting to a TCP source that emits JSON, then passing the stream to vj with options that specify which keys to display and how to present them. The README shows an example where a live feed from a cryptocurrency chart API is reformatted to show only the symbol and price fields, producing a clean, column‑aligned view.

vj is distributed under a BSD license, is considered stable, and is available as a CLI component for inclusion in development workflows.
