App::PipeFilter::JsonCut - return specified fields from a JSON stream
VERSION
version 0.003
SYNOPSIS
Here is the jcut(1) pipeline filter.
#!/usr/bin/perl
use App::PipeFilter::JsonCut;
exit App::PipeFilter::JsonCut->new_with_options()->run();DESCRIPTION
App::PipeFilter::JsonCut implements the jcut(1) pipeline filter. It's modeled after the UNIX cut(1) utility. Please see jcut(1) for usage instructions.
This class subclasses App::PipeFilter::Generic::Json.
PUBLIC ATTRIBUTES
o
The o() attribute specifies one or more fields to extract from input and write to output. All other fields will be discarded. MooseX::Getopt sets o() to the values of the -o options from the command line.
PUBLIC METHODS
transform
The transform() method iterates over its input and returns new records composed of only the fields named in the o() attribute.

perldoc -m App::PipeFilter::JsonCutApp::PipeFilter::JsonPath is a similar pipeline filter that understands JSON::Path expressions. Evaluating JSON::Path expressions incurs noticeable overhead for large data sets, so use jcut(1) whenever possible.
App::PipeFilter has top-level documentation including a table of contents for all the libraries and utilities included in the project.
