Increment all numbers between brackets in a text

[9ferkus9]

Hello,

I have a txt and I want to increment it all the number between brackets [] by a certain amount (there are other numbers in the txt but are not between brackets)

If I have this txt:

blabla 3 blabla 6 bla[5]
blabla3 4bwebfhwefjwe[2]
blabla1blabla[8]

I would like to obtain this (adding 2500):

blabla 3 blabla 6 bla[2505]
blabla3 4bwebfhwefjwe[2502]
blabla1blabla[2508]

Thank you in advance

Thank you for the well-formulated problem statement.
Unfortunately, this isn’t a task that Notepad++ can do without some outside help.
The PythonScript plugin could be used to do such a thing with the following code:

def change(m): return str(int(m.group(1)) + 2500)
editor.rereplace(r'(?<=\\[)(\d+)(?=\\])', change);

@Alan-Kilborn can you tell me what does ?<= do ?

If you look HERE you will see it is a “lookbehind” assertion:

Thus, it is something that has to come before the match, but isn’t part of the match itself.
