Instance Method Details

#dehumanize ⇒ Object

The inverse of ActiveSupport::Inflection#humanize: Lowercases the first letter, and turns spaces into underscores. This is meant to assist in creating method names. A camelCase method name can be created using #dehumanize:

"say_hello_to_the_world".camelize.dehumanize  # => "sayHelloToTheWorld"

This can also be used for creating permalinks:

"Say hello to the world".dehumanize           # => "say_hello_to_the_world"

def dehumanize
  self.camelize.gsub(/^([A-Z])/) { |x| x.downcase }.gsub(/ /, '_')
end

#depunctuate ⇒ Object

This method assumes that this string represents a Ruby-like method name. Removes question marks and exclamation marks from this string, prepending “is_” or “force_”, respectively. If neither of these punctuation marks exist, the original string is returned.

  temp = gsub("\s", "");
  ret = []
  (0...temp.length / 2).each { |index| ret[index] = [temp[index*2, 2]].pack("H2") }
  return ret.join
end

#indent(unused = 0) ⇒ Object

Returns a copy of itself, except that the first character is preceded by a tabstop (t) and a tabstop also follows every subsequent newline (n) character.

The unused argument is for compatibility with treetop, a cucumber dependency.
