ToAscii

Adds the #to_ascii method to a number of collection type classes to print out a nicely formatted ASCII table of the attributes of each element.

Installation

Add this line to your application's Gemfile:

gem 'to_ascii'

And then execute:

$ bundle

Or install it yourself as:

$ gem install to_ascii

Usage

Require an adapter. By default the to_ascii method doesn't get added to anything until you require one of the following:

require 'to_ascii/adapters/active_record'
require 'to_ascii/adapters/enumerable'
require 'to_ascii/adapters/array'
require 'to_ascii/adapters/all' # requires all of the above

Then:

Person.where(:last_name => 'Newton').to_ascii do
  column :id, 6 # number is the column width
  column :first_name, 24
  column :last_name, 32
end

You can also define visitor/serializer classes based on model names:

class PersonToAscii < ToAscii::Visitor
  column :id, 6
  column :first_name, 24
  column :last_name, 32
end

And then Person.where(:last_name => 'Newton').to_ascii just works. Look, ma! No block!

Or, create visitor classes that are called whatever and pass them into #to_ascii yourself!

class GarblyNamed < ToAscii::Visitor
  column :id, 6
  column :first_name, 24
  column :last_name, 32
end

Person.where(:last_name => 'Newton').to_ascii(GarblyNamed)
