Fellow Notepad++ Users,

Could you please help me with the following search-and-replace problem I am having?

I want to delete all lines with dates older than a week old.

Here is how I would like the data to look.

To accomplish this, I have tried using the following Find/Replace expressions and settings.

I have found no help from someone doing this.

Thank you.

Is there any reason you just didn’t continue posting to THIS thread?

It cannot be done this way, because how are you going to tell Find/Replace what “a week” means?

And why did you say “following” when nothing follows?

Here’s a simple PythonScript that seems to accomplish the goal:

# -*- coding: utf-8 -*-
from __future__ import print_function

from Npp import *
import datetime as dt
import time

#-------------------------------------------------------------------------------

class T23284(object):

    def __init__(self):
        date_current = dt.datetime(*time.localtime()[:6])
        def replace_func(m):
            date_in_question = dt.datetime(*time.strptime(m.group(1), '%m/%d/%y')[:6])
            return '' if (date_current - date_in_question).days > 7 else m.group(0)
        editor.rereplace(r'(?-s)^,\d*?,\d*?,(\d{2}/\d{2}/\d{2}).*(\R|\z)', replace_func)

#-------------------------------------------------------------------------------

if __name__ == '__main__': T23284()
