I'm doing some code generation and need to convert from CamelCase to
whatever_this_is_called. Wikipedia has a page for CamelCase but not
underscore separated words.
I'm thinking that someone must have done this already, and got the
edge cases sorted out, so rather than coming up with a wheel with an
iron tyre I'd search... for what? Is there a single correct term
for how we name methods in Ruby?
Thank you,
Hugh

Hi,
Ruby on Rails have similar things. You should take a look at Active Support, and particulary the ActiveSupport::CoreExtensions::String::Inflections class. The "underscore" method can be used to transform a string from CamelCase to underscore_seprated_words.

class String
# "FooBar".snake_case #=> "foo_bar"
def snake_case
return self unless self =~ %r/[A-Z]/
self.reverse.scan(%r/[A-Z]+|[^A-Z]*[A-Z]+?/).reverse.map{|word| word.reverse.downcase}.join '_'
end
# "foo_bar".camel_case #=> "FooBar"
def camel_case
return self if self =~ %r/[A-Z]/ and self !~ %r/_/
words = self.strip.split %r/\s*_+\s*/
words.map!{|w| w.downcase.sub(%r/^./){|c| c.upcase}}
words.join
end
end
