A textmate like folder search using picky. This is just a prototype.

textmate.rb

require 'picky'
require 'facets'
require 'facets/array/combination.rb'

Picky.logger = Picky::Loggers::Silent.new

input = ARGV

Folder = Struct.new(:id, :name)
folders = Dir[ENV['HOME'] + "/**"].
  each_with_index.map { |name, idx| Folder.new(idx, name) }

puts folders
  
include Picky # So we don't have to type Picky:: everywhere.

class Textmate < Partial::Strategy
  def each_partial token, &block
    token.split('/').each do |word|
      chars = word.chars.to_a
      1.upto(word.size) do |n|
        chars.combination(n).each { |comb| 
          yield comb.join }
      end
    end
  end
end
    
folder_index = Index.new(:folders) do
  source folders
  category :name, partial: Textmate.new
end

folder_index.index

puts 

folder_search = Search.new folder_index

require 'pp'
result = folder_search.search input.join(' ')
puts result
pp result.allocations

I'm glad :) One thing you can assume with Picky is that it's relatively fast - without wanting to sound glib. When overriding internals be sure not to allocate too many resources, especially in code that's called many times. But you know all that already :) Have fun! It's a great idea and I'd love to see it go somewhere!
