The current regex for ruby constants has an error and matches way more than it should. It overwrites the reserved words and most variable names with bright blue - making it hard to read. Change the regex to match exactly 1 of $|@|@@ instead of matching 1 or 0.

## Here is an example for Ruby.

## Constants

## Some unique things we want to stand out

## Regular expressions
|

## Shell command expansion is in `backticks` or like %x{this}. These are
