Trying to duplicate lines and parse list in NPP


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.


Solution

  • 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
