json_xs

JSON_XS(1p)						User Contributed Perl Documentation					       JSON_XS(1p)

NAME

       json_xs - JSON::XS commandline utility

SYNOPSIS

	  json_xs [-v] [-f inputformat] [-t outputformat]

DESCRIPTION

       json_xs converts between some input and output formats (one of them is JSON).

       The default input format is "json" and the default output format is "json-pretty".

OPTIONS

       -v  Be slightly more verbose.

       -f fromformat
	   Read a file in the given format from STDIN.

	   "fromformat" can be one of:

	   json - a json text encoded, either utf-8, utf16-be/le, utf32-be/le
	   storable - a Storable frozen value
	   storable-file - a Storable file (Storable has two incompatible formats)
	   clzf - Compress::LZF format (requires that module to be installed)
	   yaml - YAML (avoid at all costs, requires the YAML module :)
	   eval - evaluate the given code as (non-utf-8) Perl, basically the reverse of "-t dump"
       -t toformat
	   Write the file in the given format to STDOUT.

	   "toformat" can be one of:

	   json, json-utf-8 - json, utf-8 encoded
	   json-pretty - as above, but pretty-printed
	   json-utf-16le, json-utf-16be - little endian/big endian utf-16
	   json-utf-32le, json-utf-32be - little endian/big endian utf-32
	   storable - a Storable frozen value in network format
	   storable-file - a Storable file in network format (Storable has two incompatible formats)
	   clzf - Compress::LZF format
	   yaml - YAML
	   dump - Data::Dump
	   dumper - Data::Dumper
	       Note that Data::Dumper doesn't handle self-referential data structures correctly - use "dump" instead.

EXAMPLES

	  json_xs -t null <isitreally.json

       "JSON Lint" - tries to parse the file isitreally.json as JSON - if it is valid JSON, the command outputs nothing, otherwise it will print
       an error message and exit with non-zero exit status.

	  <src.json json_xs >pretty.json

       Prettify the JSON file src.json to dst.json.

	  json_xs -f storable-file <file

       Read the serialised Storable file file and print a human-readable JSON version of it to STDOUT.

	  json_xs -f storable-file -t yaml <file

       Same as above, but write YAML instead (not using JSON at all :)

	  lwp-request http://cpantesters.perl.org/show/JSON-XS.json | json_xs

       Fetch the cpan-testers result summary "JSON::XS" and pretty-print it.
