== Welcome to Printr Printr is an interface to serial/usb/plain_file printers on *nix systems. You can use it with your udev rules etc. It is built as a rails engine, and should be used as a gem. You can pull the latest edition from this repo, or: #Gemfile gem 'printr' Then run bundle install The rails g printr:install and rails g printr:views If you pass in a :scope, it will set that to the view directory. Normally it is: app/views/printr/view.prnt.erb, if you don't want it to be that, you can set the :scope rails g printr:views printer_views would install the views to app/views/printer_views/#{view}.prnt.erb The default source for printer configurations is :yaml, and expects a printrs.yml file to be present in RAILS_ROOT/config/, you can also feed it off of an ActiveRecord, in initializers/printr.rb config.printr_source = {:active_record => { :class_name => YourActiveRecordClass, :name => :attribute_name, :path => :attribute_name } } If you set the scope, make sure to add: config.scope = 'the_scope_you_passed' Where: :name must be an attribute of the active record object, and the value it resolves to must be a snake_case_name :path must be the full path to the printer, like /dev/som0 or /home/user/printer.txt ==Basic Usage: @printer = Printr.new @printer.the_name_of_some_printer "text" ==Advanced Usage Create a printr folder in your views directory for your rails app. name the view #{some_name}.prnt.erb So for instance, say you want an item view: /views/printr/item.prnt.erb Then somewhere in your app, call: @printer = Printr.new @printer.the_name_of_some_printer "item",binding
