PPJ

A simple Rust CLI that prettifies JSON.

Getting Started

• Install: cargo install ppj
• Build: cargo build
• Run: ppj
• Test: cargo test

Usage

ppj accepts a JSON string as a positional argument, or reads JSON from stdin when no positional input is provided. It outputs pretty-printed JSON to stdout by default.

Basic

• From a positional argument:
  • ppj '{"key":"value","nums":[1,2]}'
• From stdin:
  • echo '{"key":"value","nums":[1,2]}' | ppj

Output to file

Use -o/--out to write the prettified JSON to a file. Parent directories are created if they don’t exist.

• ppj '{"key":"value"}' -o output.json

Print and write

Use -p/--print to also print to stdout when writing to a file.

• ppj '{"key":"value"}' -o output.json -p

Options

• -o, --out <DIR>: Output file path.
• -p, --print: Print prettified JSON to stdout even when --out is set.
