Picky on MacRuby example script

picky-tryout.rb

# coding: utf-8
require 'rubygems'
# require fileutils to use FileUtils. Otherwise an error gets raised.
# uninitialized constant Picky::Backends::Helpers::File::FileUtils (NameError)
# 	from /Volumes/Home/Projects/utf8/picky/server/lib/picky/backends/prepared/text.rb:66:in `open'

require 'fileutils'
require 'picky'

include Picky

Utf8Symbol = Struct.new(:id, :symbol, :bytecode, :html_entity, :description)
symbols = [
  Utf8Symbol.new(1, '🐒', 'f09f9092', '&#128018', 'MONKEY'),
  Utf8Symbol.new(2, '🐵', 'f09f90b5', '&#128053', 'MONKEY FACE'),
  Utf8Symbol.new(3, '🙈', 'f09f9988', '&#128584', 'SEE-NO-EVIL MONKEY'),
  Utf8Symbol.new(4, '🙉', 'f09f9989', '&#128585', 'HEAR-NO-EVIL MONKEY'),
  Utf8Symbol.new(5, '🙊', 'f09f998a', '&#128586', 'SPEAK-NO-EVIL MONKEY')
]

monkey_index = Index.new(:monkey_index) do
  source { symbols }
  indexing removes_characters: /[^a-z0-9\-\s\"\~\*\:\,]/i,
           splits_text_on: /[\s\-]/
  category :description
end

monkey_search = Search.new(monkey_index) do
  searching removes_characters: /[^a-z0-9\-\s\/\_\&\.\"\~\*\:\,]/i, # Picky needs control chars *"~:, to pass through.
            stopwords:          /\b(and|the|of|it|in|for)\b/i,
            splits_text_on:     /[\s\/\-\&]+/
end

monkey_index.load rescue monkey_index.index

p evil_monkeys = monkey_search.search("evil").ids

Indexing by default splits only on \s, so SEE-NO-EVIL is indexed as is. So add option splits_text_on: /\s-/ to index EVIL as a word to have it be found.

I hope that helps :)

Nice script, btw :)

Thanks for your help.
I'm really trying to get it working, but I fail even with this script.
No matter what ruby I am using, the result is always an empty array. I think something else must be wrong with my script. I'll sleep over it.

 $ rm -rf index/; ruby picky-tryout.rb
.Picky is indexing using a single process: TD Done in 0s.
[]
$ rm -rf index/; macruby picky-tryout.rb

:S
I'll run it in the morning and will write you if I am successful. Cheers!

Hi Lukas,

I just saw what it is. I was too focused on the Picky code when in fact it was in the Ruby part. A Struct takes a list of params, not a hash of params. So it should be

Utf8Symbol.new(1, '', 'f09f9092', '&#128018', 'MONKEY'),
Utf8Symbol.new(2, '', 'f09f90b5', '&#128053', 'MONKEY FACE'),
Utf8Symbol.new(3, '', 'f09f9988', '&#128584', 'SEE-NO-EVIL MONKEY'),
Utf8Symbol.new(4, '', 'f09f9989', '&#128585', 'HEAR-NO-EVIL MONKEY'),
Utf8Symbol.new(5, '', 'f09f998a', '&#128586', 'SPEAK-NO-EVIL MONKEY')

(The gist comment had problems with the special characters, so I removed them)

What happens now is that a hash is passed to the @id instance variable, the rest of the attributes being nil.

You should also let the hypen through in the removes_characters, so that it can split on it, if I am not mistaken.

Cheers :)

Haha, shame on me... I've overseen the problem with the Struct initialization too. I'm more used to OpenStruct these days...
And indeed removes_characters: must keep the hyphen. So I changed those on indexing and searching.
Anyways, it works now! Thank you so much for your time you spend helping me out with this.

$ rm -rf index/; macruby picky-tryout.rb

[3, 4, 5]

So that's where those evil monkeys are...!

Now worries, glad to help :)
