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:

-t toformat

Write the file in the given format to STDOUT.

"toformat" can be one of:

-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.
