Creating a tally count of line duplicates

[a-raccoon]

Hello, I am wondering if Notepad++ has the ability to not just remove duplicate lines, but also count them and generate a tally table. Here is a javascript website that does what I’m looking for, but I would love if NPP also had this capability.

fox
fox
dog
cat
fox
cat
fox

becomes

COUNT    | LINE
-----------------------------------------------------
       4 | fox
       2 | cat
       1 | dog
-----------------------------------------------------
       7 | TOTAL LINES

There isn’t a native function within Notepad++, however a search through this forum found this post with a PythonScript program that with slight modification could do a line histograph. I note your example suggested your lines are in fact single words each on a different line, so if that’s the case then the program as it stands should work.

Its here.

Thanks for the find @terry-r, I’ll find that PythonScript plugin and play with it.

I assume I should be able to change the regex pattern to suit my needs in the line editor.research('\w+', match_found) to something like editor.research('^.*$', match_found) to perform a histogram by line.

Much appreciated.
