= Wukong-Meta
Wukong-Meta is a Wukong plugin which extracts metadata about models, processors, flows, and jobs from a deploy pack.
== Installation
Just make sure Wukong-Meta is somewhere in your deploy pack's Gemfile
# in Gemfile.rb
gem 'wukong-meta'and do a bundle update to ensure the code is installed and availabl
locally within your deploy pack.
== Usage
Wukong-Meta provides the wu-show command which can be used to show
metadata.
Try it without any arguments to produce a listing of all models, processors, flows, and jobs it can find within the deploy pack.
$ bundle exec wu-show
You can also pass a specific kind of object
$ bundle exec wu-show models
$ bundle exec wu-show processors
$ bundle exec wu-show dataflows
$ bundle exec wu-show jobs
Or the name of a specific model, processors, dataflow, or job (as reported in the second column of the above output):
$ bundle exec wu-show MyModelName
$ bundle exec wu-show my_processor
$ bundle exec wu-show my_dataflow
$ bundle exec wu-show my_job
The wu-show command colorizes output based on the type of the
object. You can see a legend of what colors correspond to what kinds
of objects:
$ bundle exec wu-show legend
=== Output Formats
The wu-show command can output its data in several different
formats, controlled by the --to option.
Try JSON output
$ bundle exec wu-show processors --to=json
Or TSV
$ bundle exec wu-show processors --to=tsv
The default behavior is equivalent to --to=text.
