Do the following

copy the script
goto Plugins->Python Script->New Script
give it a meaningful name and press save button
paste the script into the newly ceated document
save it
open one of your BR! Source files
click on Plugins->Python Script->Scripts->NAME_OF_THE_NEWLY_CREATED_PYTHONSCRIPT

If you want to know the details, let me know.

Eko palypse

btw, when it works like you want and want it to be available automatically
on every npp startup we need to create a USER startup.py but
I guess this can be discussed it the script is useful to you at all

Michael Miller31

Thanks for putting the time into this!

First, will this work on 64 bit N++?

I had some trouble finding a version of Python Script that was compatible but I managed to find a beta version.

also, I’m getting this error.

Traceback (most recent call last):
File “C:\Users\mmiller\AppData\Roaming\Notepad++\plugins\Config\PythonScript\scripts\create_strings.py”, line 4, in <module>
import ctypes
File “C:\Program Files\Notepad++\plugins\PythonScript\lib\ctypes_init_.py”, line 7, in <module>
from _ctypes import Union, Structure, Array
ImportError: No module named _ctypes

Eko palypse

Yes, as I’m using x64 version as well.
Where did you download pythonscript plugin from?
Why didn’t you use Plugin Manager?
The official release channel for python script plugin is here.

Michael Miller31

I don’t have plugin manager so I went through http://docs.notepad-plus-plus.org/index.php?title=Plugin_Central .

Thanks for dealing with my idiocy. Going through plugin manager worked perfectly. Is there any way I can donate for your time?

@Michael-Miller31

Is there any way I can donate for your time?

yes, we urgently need 5 macbook pro’s. 👍
thanks in advance. 😂

Eko palypse

Thank you very much for asking and yes there is one thing
you could do if you like :-)
It might sound strange but if you have or know a cooking recipe
which is worth testing - I would appreciate.
I know tastes are different so … :-)

Eko palypse

@Meta-Chuh

REALLY - macbooks … NOWADAYS … :-D

Michael Miller31

I will get you a recipe when I get home from work. :-)

The macbooks will take some time. :-D

Michael Miller31

https://imgur.com/a/GWRaqec @Eko-palypse here’s my favorite recipe for muffins. :-D

Thanks again for your help.

I also realized afterwards that there are a few internal functions that end with $ and don’t start with fn but I just modified the regex to take care of them.

Eko palypse

@Michael-Miller31

thank you thank you very much - very much appreciated - I LOVE MUFFINS (who doesn’t ?)
And also nice to see that you already made the script do what you want.
Have a nice day.

@Michael-Miller31

Much better to have an actual recipe than simply all the talk of “baking cookies” that goes on around here sometimes!

Eko palypse

Help, I need somebody help I need somebody heeeelllppp :-D

Meta Chuh

@Eko-palypse

yesterday … all my troubles seemed so far away :-D

Alan Kilborn

I see the Beatles song lyrics references, but I’m unsure why Eko started it??
