English Sentence to Camel-cased method name

Question

I had to convert a series of sentences into camel-cased method names. I ended writing something for it. I am still curious if there's something simpler for it.

Given the string a = "This is a test." output thisIsATest

I used for following:

a.downcase.gsub(/\s\w/){|b| b[-1,1].upcase }

Answer 1

"active_record".camelize(:lower)

output : "activeRecord"

use these

Answer 2

Not sure it's better as your solution but it should do the trick:

>> "This is a test.".titleize.split(" ").join.camelize(:lower)
=> "thisIsATest."

• titleize: uppercase every first letter of each word
• split(" ").join: create an array with each word and join to squeeze the spaces out
• camelize(:lower): make the first letter lowercase

You can find some more fun functions in the Rails docs: http://api.rubyonrails.org/classes/ActiveSupport/CoreExtensions/String/Inflections.html

Answer 3

"Some string for you".gsub(/\s+/,'_').camelize(:lower) #=> "someStringForYou"

1. gsub: Replace spaces by underscores
2. camelize: java-like method camelcase

Answer 4

You might try using the 'English' gem, available at http://english.rubyforge.org/

require 'english/case'

a = "This is a test."

a.camelcase().uncapitalize() # => 'thisIsATest
