# ydump(1)

JSON pretty printer

## NAME

ydump - JSON pretty printer

## SYNOPSIS

**ydump \[*Options...*\] \[*file*\]**

## DESCRIPTION

**ydump** pretty prints data in the extended **JSON** format of the **yojson** library.  **JSON** stands for JavaScript Object Notation and is a lightweight data-interchange format.

**ydump** reads from standard input if the *file* argument is omitted.

## OPTIONS

- **-o \<file\>**

  pretty print to *file* instead of standard output

- **-std**

  use **JSON** standard syntax only: Convert tuples and variants into standard **JSON,** refuse to print NaN and infinities, require the root node to be either an object or an array.

- **-c**

  compact output

- **-s**

  streaming mode: read and write a sequence of **JSON** values instead of just one (this is the default).

- **-u**

  disable streaming mode: A single **JSON** record is expected.

- **-sort**

  sort object fields (default: preserve internal field order)

- **-ob**

  convert to biniou format and pretty print that (experimental)

- **-version**

  print version and exit

- **-help \| --help**

  print options
