Hash and Curly Braces inside a Ruby String with snippets

I was looking for a way to save myself an annoyance in Vim when interpolating a value inside a Ruby string.

Problem

GIVEN that the cursor is inside a Ruby string

WHEN I type #

THEN Vim should insert into the text #{}

AND my cursor should be between the curly braces

AND after I finish typing inside the curly braces there should be a way to jump out of them.

Solution

snippet #
	#{${1}} ${2}

Thus, when I type #-TAB:

1. Vim adds the curly braces
2. Places the cursor inside the braces
3. And when I finish typing, I can press tab to jump out.

I never used the original snippet anyway, because I use Tim Pope’s excellent plugin, Vim Commentary.
