Using regex to duplicate a selection and replacing some characters

Question

Probably a terrible title.

I am trying to take the following:

Joe Dane
Bob Sagget
Whitney Houston
Some
Other
Test

And trying to produce:

JOE_DANE("Joe Dane"),
BOB_SAGGET("Bob Sagget"),
WHITNEY_HOUSTON("Whitney Houston"),
SOME("Some"),
OTHER("Other"),
TEST("Test"),

I'm using Notepad++ and am close but not good enough at regex to figure out the remaining expression. So far, this is what I have:

Find what: (^.*)
Replace with: \1 \(\"\1\"\),
Produces: Joe Dane("Joe Dane"),

I've tried replacing with: \U$1 \(\"\1\"\), but this also impacts the second instance of \1 with upper case. It also does not replace the whitespace with an underscore _.

Answer 1

This can be done in a single step.

If you don't have more than 2 words in a line:

• Ctrl+H
• Find what: ^(\S+)(?: (\S+))?$
• Replace with: \U$1(?2_$2)\E\("$0"\),
• CHECK Wrap around
• CHECK Regular expression
• Replace all

Explanation:

^               # beginning of line
(\S+)           # group 1, 1 or more non space
(?: (\S+))?     # non capture group, a space, group 2, 1 or more non space, optional
$

Replacement:

\U          # uppercased
$1          # group 1
(?2_$2)     # if group 2 exists, add and underscore before
\E          # end uppercase
\("$0"\),   # the whole match with parens and quote

If you have more than 2 words (up to 5), use:

• Find ^(\S+)(?: (\S+))?(?: (\S+))?(?: (\S+))?(?: (\S+))?

• Replace: \U$1(?2_$2)(?3_$3)(?4_$4)(?5_$5)\E\("$0"\),

I you have more thans five word, add as many (?: (\S+))? as needed.
