json_xs

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 :)

-t toformat

Write the file in the given format to STDOUT.

"fromformat" 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

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 :)

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