NAME

App::DPath - Cmdline tool around Data::DPath

SYNOPSIS

This module provides a cmdline tool around Data::DPath.

Query some input data with a DPath to stdout.

Default data format (in and out) is YAML, other formats can be specified.

  $ dpath '//some/dpath' data.yaml

Use it as filter:

  $ dpath '//some/dpath' < data.yaml > result.yaml
  $ cat data.yaml | dpath '//some/dpath' > result.yaml
  $ cat data.yaml | dpath '//path1' | dpath '//path2' | dpath '//path3'

You can define different input/output formats (yaml, json, xml, ini, dumper, tap, flat) with -i and -o.

See documentation for the dpath utility for more.

DEFAULT COMMAND CHEATING

The dpath tool is based on App::Cmd which is using sub commands. All the above examples use the default subcommand search which is silently inserted into the argument/options list if no subcommand is given.

So instead of

  $ dpath -i json -o dumper data.json

you can also write

  $ dpath search -i json -o dumper data.json

Other available subcommands are help and commands.

The built in help always fully refers to subcommands.
