Trying to duplicate lines and parse list in NPP

Question

Given a list of profile image links in markdown with varying name lengths:

![[Last, First.jpg]]
![[Longerlast, Longerfirst.jpg]]
etc

How can I convert to the following using regex in NPP?

![[Last, First.jpg]]
::Last, First
![[Longerlast, Longerfirst.jpg]]
::Longerlast, Longerfirst
etc

I was able to isolate the first and last patterns through trial and error, but am running into a wall before a complete solution.

Answer 1

• Ctrl+H
• Find what: ^!\[\[(.+?)\.jpg]]\K
• Replace with: \n::$1
• TICK Wrap around
• SELECT Regular expression
• UNTICK . matches newline
• Replace all

Explanation:

^           # beginning of line
!\[\[       # literally ![[
(.+?)       # group 1, 1 or more any character, not greedy
\.jpg]]     # literally .jpg]]
\K          # forget all we have seen until this position

Replacement:

\n          # liebreak, you can use \r\n for Windows EOL
::          # ::
$1          # content of group 1 i.e. last, first
