cpanel_json_xs − Cpanel::JSON::XS commandline utility
cpanel_json_xs [−v] [−f inputformat] [−t outputformat]
cpanel_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".
|
−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
json-nonref − json according to RFC 7159
json-relaxed − json with all relaxed options
json-unknown − json with allow_unknown
storable − a Storable frozen value
storable-file − a Storable file (Storable has two
incompatible
formats)
bencode − uses one of
Net::BitTorrent::Protocol::BEP03::Bencode,
Bencode or the broken 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 − loose YAML (requires YAML)
yaml-tiny − loose YAML (requires YAML::Tiny or
CPAN::Meta::YAML)
yaml-xs − strict YAML 1.2 (requires YAML::XS)
yaml-syck − YAML (requires YAML::Syck)
cbor − CBOR (via CBOR::XS)
string − do not attempt to decode the file data
sereal − Sereal (via Sereal::Decoder)
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 with sorted
object keys
json-stringify − as json-pretty with allow_stringify
json-relaxed − as json-pretty, but with the additional
options
−>allow_stringify−>allow_blessed−>convert_blessed−>allow_unknown −>allow_tags−>stringify_infnan(1)
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)
bencode − uses one of
Net::BitTorrent::Protocol::BEP03::Bencode,
Bencode or the broken Convert::Bencode, if available (used
by
torrent files, among others)
clzf − Compress::LZF format
yaml − loose YAML (requires YAML)
yaml-tiny − loose YAML (requires YAML::Tiny or
CPAN::Meta::YAML)
yaml-xs − strict YAML 1.2 (requires YAML::XS)
yaml-syck − YAML (requires YAML::Syck)
dump − Data::Dump
dumper − Data::Dumper
string − writes the data out as if it were a string
sereal − Sereal (via Sereal::Encoder)
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 $_, and whatever is in there is written out afterwards.
cpanel_json_xs −t none <isitreally.json
"JSON Lint" − tries to parse the file isitreally.json as JSON − if it is valid JSON, the command outputs nothing, otherwise it will print an error message and exit with non-zero exit status.
<src.json cpanel_json_xs >pretty.json
Prettify the JSON file src.json to dst.json.
cpanel_json_xs −f storable−file <file
Read the serialized Storable file file and print a human-readable JSON version of it to STDOUT.
cpanel_json_xs −f storable−file −t yaml <file
Same as above, but write YAML instead (not using JSON at all :)
cpanel_json_xs −f none −e '$_ = [1, 2, 3]'
Dump the perl array as UTF−8 encoded JSON text.
<torrentfile cpanel_json_xs −f bencode −e '$_ = join "\n", map @$_, @{$_−>{"announce−list"}}' −t string
Print the tracker list inside a torrent file.
lwp−request http://cpantesters.perl.org/show/Cpanel−JSON−XS.json | cpanel_json_xs
Fetch the cpan-testers result summary "Cpanel::JSON::XS" and pretty-print it.

Error: YAML_LOAD_ERR_BAD_MAP_ELEMENT
Compare YAML en− and decoders, and see that YAML::XS generates unparsable YAML <https://github.com/ingydotnet/yaml−libyaml−pm/issues/9>
