Improvise

Improvise generates random words by learning from existing text.

Installation

Add this line to your application's Gemfile:

gem 'improvise'

And then execute:

$ bundle

Or install it yourself as:

$ gem install improvise

Require the 'improvise' gem:

require 'improvise'

Create a new dictionary with depth 3:

dict = Improvise::ForwardDictionary.new(3)

Or create a reversed dictionary with depth 3:

dict = Improvise::ReverseDictionary.new(3)

Learn from a list of existing words:

dict.learn!([
    'ruby', 
    'sapphire', 
    'pearl', 
    'diamond', 
    'amethyst', 
    'topaz', 
    'emerald'
])

Generate a 6-letter word:

dict.generate_word(6)

Generate a 7-letter word, starting with 'top':

dict.generate_word(7, 'top')

Write a dictionary in Ruby's Marshal format to a file called 'dict.bin':

dict_file = File.open('dict.bin', 'w')
Improvise::IO::DictionaryWriter.write(dict_file, dict)

Write a dictionary in Ruby's Marshal format, gzipped, to a file called 'dict.bin.gz':

dict_file = File.open('dict.bin.gz', 'w')
Improvise::IO::DictionaryWriter.write(dict_file, dict, gzip: true)

Write a dictionary in json format, gzipped, to a file called 'dict.json.gz':

dict_file = File.open('dict.json.gz', 'w')
Improvise::IO::DictionaryWriter.write(dict_file, dict, format: :json, gzip: true)

Note: writing a dictionary closes the passed IO object.

Restore a dictionary from a file called 'dict.bin' in Ruby's Marshal format:

dict_file = File.open('dict.bin', 'r')
dict = Improvise::IO::DictionaryReader.read(dict_file)

Restore a dictionary from a file called 'dict.bin.gz' in Ruby's Marshal format, gzipped:

dict_file = File.open('dict.bin.gz', 'r')
dict = Improvise::IO::DictionaryReader.read(dict_file, gzip: true)

Restore a dictionary from a file called 'dict.json.gz' in json format, gzipped:

dict_file = File.open('dict.json.gz', 'r')
dict = Improvise::IO::DictionaryReader.read(dict_file, format: :json, gzip: true)

Note: reading a dictionary closes the passed IO object.

A command-line interface to the library has been provided under the name 'improvise'. Run improvise --help to get a list of available commands.
