Have you seen this thing in new Ruby (2.3+)?
(1..10).cover(2)
# NoMethodError: undefined method `cover' for 1..10:Range
# Did you mean? cover? <---- ThisIf you wanted to provide same functionality for your code ("Lexem x is not recognized. Did you
mean y?") you can use did_you_mean gem bundled with
your Ruby. But it is a bit hard: gem's dictionary lookup interface is a bit hard to follow, and
moreover, it changes dramatically from Ruby 2.3 to Ruby 2.4, and standalone gem version (available
for Ruby 2.1-2.2) has one more different interface.
did_you solves this problem by providing simple, Ruby version-agnostic inteface to did_you_mean
gem.
Important: This library's sole purpose is providing simple, consistent interface between
different did_you_mean versions. If your only target version is Ruby 2.4, you can just go with
did_you_mean's current way:
DidYouMean::SpellChecker
.new(dictionary: %w[param return tag abstract])
.correct('params')Install it as a gem did_you or add gem 'did_you' to your Gemfile. (On Ruby < 2.3 it will install
old did_you_mean, on newer ones has no additional dependencies.)
Then just...
# First parameter is word you want to check, second -- known words in the context
DidYou::Spell.check('params', %w[param return tag abstract]) # => ["param"]That's it. ¯\_(ツ)_/¯
