Regex to replace values that include part of match in replacement in sublime?

Question

I've come up with this regex that finds all words that start with $ and contain _ underscores:

\$(\w+)_(\w+)

I'm basically searching for variables, like $var_foo etc.

How do I replace stuff using the regex groups?

For example, how can I remove the underscore and make the next letter uppercase, like $varFoo ?

The replacement expression is:

\$\1\u\2

• \1, \2 are the captures (or $1, $2)
• \u up-cases (see the Replacement String Syntax section).

See the Regular Expressions chapter ^{(in the TextMate docs)} for more information.

There's already a package that does this, and more:

Sublime text 3 does not take regex in the "Replace With" field. If I put a regex there, it just dumps that regex as string in the editor. How can I use regex in "Replace" field in sublime? Basically, I want to search all words (basically hex colour values) beginning with "#" and add some string before and after that word. Using "\#\w+", I can find all such words, but if I do string1\#\w+string2, it outputs it as it is, without replacing regex with actual word. – Olympiaolympiad
