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 basi

Answer 1

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:
