Synopsis

    json_pp [-v] [-f from_format] [-t to_format] [-json_opt options_to_json1[,options_to_json2[,...]]]

Description

Format types:

options to JSON::PP

Acceptable options are:

    ascii latin1 utf8 pretty indent space_before space_after relaxed canonical allow_nonref
    allow_singlequote allow_barekey allow_bignum loose escape_slash indent_length

Multiple options must be separated by commas:

    Right: -json_opt pretty,canonical

    Wrong: -json_opt pretty -json_opt canonical

-v

Verbose option, but currently no action in fact.

-v

Prints version and exits.
