Nodeattr

Ruby implementation of nodeattr.

The goal is to replicate functionality of nodeattr as defined by the Genders library developed by LLNL.

Current implementation is very limited in that only simple gender query works. This will be expanded upon to provide union, intersection, and exclusion of genders. Values are also not yet supported, but are planned for a future update.

Included are the nodeattr class and the nodeattr command line tool.

Installation

Add this line to your application's Gemfile:

gem 'nodeattr'

And then execute:

$ bundle

Or install it yourself as:

$ gem install nodeattr

Class Usage

require 'nodeattr'

n = NodeAttr.new

if nodes = n.query(@gender)
  puts nodes.join(@sep)
end
