JSON_XS(1)            User Contributed Perl Documentation           JSON_XS(1)
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
           cbor - CBOR (RFC 7049, CBOR::XS), a kind of binary JSON
           storable - a Storable frozen value
           storable-file - a Storable file (Storable has two incompatible
           formats)
           bencode - use Convert::Bencode, if available (used by torrent
           files, among others)
           clzf - Compress::LZF format (requires that module to be installed)
           eval - evaluate the given code as (non-utf-8) Perl, basically the
           reverse of "-t dump"
           yaml - YAML format (requires that module to be installed)
           string - do not attempt to decode the file data
           none - nothing is read, creates an "undef" scalar - mainly useful
           with "-e"
       -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
           cbor - CBOR (RFC 7049, CBOR::XS), a kind of binary JSON
           cbor-packed - CBOR using extensions to make it smaller
           storable - a Storable frozen value in network format
           storable-file - a Storable file in network format (Storable has two
           incompatible formats)
           bencode - use Convert::Bencode, if available (used by torrent
           files, among others)
           clzf - Compress::LZF format
           yaml - YAML::XS format
           dump - Data::Dump
           dumper - Data::Dumper
           string - writes the data out as if it were a string
           none - nothing gets written, mainly useful together with "-e"
               Note that Data::Dumper doesn't handle self-referential data
               structures correctly - use "dump" instead.
       -e code
           Evaluate perl code after reading the data and before writing it out
           again - can be used to filter, create or extract data. The data
           that has been written is in $_, and whatever is in there is written
           out afterwards.
EXAMPLES
          json_xs -t none <isitreally.json
       "JSON Lint" - tries to parse the file isitreally.json as JSON - if it
       is valid JSON, the command outputs nothing, otherwise it will print an
       error message and exit with non-zero exit status.
          <src.json json_xs >pretty.json
       Prettify the JSON file src.json to dst.json.
          json_xs -f storable-file <file
       Read the serialised Storable file file and print a human-readable JSON
       version of it to STDOUT.
          json_xs -f storable-file -t yaml <file
       Same as above, but write YAML instead (not using JSON at all :)
          json_xs -f none -e '$_ = [1, 2, 3]'
       Dump the perl array as UTF-8 encoded JSON text.
          <torrentfile json_xs -f bencode -e '$_ = join "\n", map @$_, @{$_->{"announce-list"}}' -t string
       Print the tracker list inside a torrent file.
