Ranges and comparisons meet Turkish language.

NOTICE: This gem can create one-dimensional ranges like a..z and multi-dimensional ranges like aa..az. It can't create complex ranges like a..abc right now. I have intended to add this feature in the near future.


Add this line to your application's Gemfile:

gem 'turkish_ranges'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install turkish_ranges


require 'turkish_ranges'

include TurkishRanges

# Creating new texts

# Comparing texts containing Turkish letters
TrText.new('Ğ')      > TrText.new('Ü')       # false
TrText.new('abbası') < TrText.new('abbasi')  # true

# Creating ranges containing Turkish letters
full_upcase_range = TrText.new('A')..TrText.new('Z')
# => [A, B, C, Ç, D, E, F, G, Ğ, H, I, İ, J, K, L, M, 
#     N, O, Ö, P, Q, R, S, Ş, T, U, Ü, V, W, X, Y, Z]

full_downcase_range = TrText.new('A')..TrText.new('Z')
# => [a, b, c, ç, d, e, f, g, ğ, h, ı, i, j, k, l, m,
#     n, o, ö, p, q, r, s, ş, t, u, ü, v, w, x, y, z]

# => [aa, ab, ac, aç, ad, ae, af, ag, ağ, ah, aı, ai, aj, ak, al, 
#     am, an, ao, aö, ap, aq, ar, as, aş, at, au, aü, av, aw, ax]
