DESCRIPTION

This program creates a chart for your data structure, either in the form of an array, array of arrays, hash, array of hashes. You can use it to quickly visualize a data structure on a console.

It accepts input as JSON, or several other alternative formats (see the -i option). It by default outputs the chart as ASCII text. Other formats will be supported in the future.

This is an early release. More options, chart types, will be added in the future.

EXIT CODES

0 on success.

1 on failure.

99 on command-line options error.

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.
