Ruby tools is a collection of handy functions for Emacs ruby-mode. You can turn a string to symbol, symbol to string, single to double quote string, double to single quote string, clear string, interpolate and more...

I recommend installing via ELPA, but manual installation is simple as well:

(add-to-list 'load-path "/path/to/ruby-tools")
(require 'ruby-tools)

When ruby-mode is started, ruby-tools-mode will automatically start.

Once started, this functionality is available:

Insert:

foo(:bar)

Place cursor on :bar, then press C-' and you will see:

foo('bar')

Insert:

foo('bar')
foo("bar")

Place cursor on bar, then press C-: and you will see:

foo(:bar)
foo(:bar)

Insert:

foo('bar')

Place cursor on bar, then press C-" and you will see:

foo("bar")

Insert:

foo("bar")

Place cursor on bar, then press C-' and you will see:

foo('bar')

Insert:

foo('bar')

Place cursor on bar, then press C-; and you will see:

foo('')

Insert:

foo('bar')
foo("bar")
`bar`
%(bar)

Place cursor on bar, then press # and you will see:

foo('b#ar')
foo("b#{}ar")
`b#{}ar`
%(b#{}ar)

• Add/remove parenthesis on function call/definition
• re-builder for Ruby regex syntax

Contribution is much welcome! Ruby tools is tested using Ecukes. When adding new features, please write tests for them!
