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 :)
