NAME

jpath - Command-line tool for JSON::Path

VERSION

This document describes version 0.050 of jpath (from Perl distribution App-jpath), released on 2023-02-14.

SYNOPSIS

Usage:

% jpath [OPTIONS] <JSONPATH_EXPR> < data.json

DESCRIPTION

This script provides a simple, relatively straightforward command-line interface for JSON::Path. It accepts JSON input as well as several other formats; and similarly can output JSON or alternative formats.

This script sets $JSON::Path::Safe to 0 so you can eval Perl expressions.

EXIT CODES

0 on success.

99 on command-line options error.

OPTIONS

  • --input=STR, -i

    Pick input format. Available formats: json, yaml (using YAML::Syck), perl. Default is json.

  • --output=STR, -o

    Pick output format. Available formats: json, yaml, perl, and pretty (using Data::Format::Pretty::Console). Default is json.

FAQ

How do I turn off colors and line numbers?

Use COLOR=0 and LINUM=0, respectively. For example:

% LINUM=0 jpath ...

See Data::Format::Pretty::JSON and other Data::Format::Pretty::* for more details.

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

% prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
