No module named Npp

Alina Gubanova · Jun 20, 2019, 5:49 PM

Hi everyone!

I am trying to convert files in the directory into the UTF-8 format. This is the code:

import os;
import sys;
import Npp;
from Npp import notepad

filePathSrc="somedirectoty " # Path to the folder with files to convert

for root, dirs, files in os.walk(filePathSrc):
    for fn in files:
        if fn[-4:] == '.txt':
             notepad.open(root + "\\" + fn)
             console.write(root + "\\" + fn + "\r\n")
             notepad.runMenuCommand("Encoding", "Convert to UTF-8 without BOM")
             notepad.save()
notepad.close()

So when I try to run it, I get an error message “No module named Npp”. What do you think could be an issue? Thank you!

@Alina-Gubanova

In the Pythonscript console window if you type from Npp import notepad, does it succeed?

If it succeeds, and you then try notepad.new() does a new editing tab open?

Alina Gubanova · Jun 20, 2019, 6:21 PM

Yes, both work. the new tab opens with notepad.new().

@Alina-Gubanova

Did you create your script by doing Plugins (menu) > Pythonscript > New Script and then giving a filename? Then to run it Plugins (menu) > Pythonscript > Scripts > pick-your-named-file-from-the-list ?

Alina Gubanova · Jun 20, 2019, 6:32 PM

Okay, so I am pretty sure I did that previously, but I tried creating a new one just now, and it’s not showing up on the list. What would be the best directory to save it and do I have to add anything to the path?

Alina Gubanova · Jun 20, 2019, 6:34 PM

I have saved the previous ones to the directory in C:…\Notepad++\plugins\PythonScript\scripts

Alan Kilborn · Jun 20, 2019, 6:35 PM

@Alina-Gubanova

Well, I use a portable version of Notepad++, and the default it comes up with is ...\npp.7.7.bin\plugins\Config\Pythonscripts\scripts\ so if you are using an installed version of N++ it is going to be different but it should be relatively similar.

You are naming your script with a .py extension, right?

(I really can’t tell your level of Python expertise from your postings).

Alina Gubanova · Jun 20, 2019, 6:41 PM

Okay, so I was saving it to the default folder then. Found it now, sorry for confusion, had to reload N++ multiple times. The script is automatically saved as .py. Still getting the same mistake.
And no worries, my python expertise is not high, so I’d rather make sure that every step is correct.

You are in an area where I don’t think I can provide further help, but @dail is typing, so… :)

Alina Gubanova · Jun 20, 2019, 7:40 PM

@Alan-Kilborn thanks for your help anyway!

Hello, @alina-gubanova, @alan-kilborn, and All,

Among my numerous portable versions of Notepad++, installed on my laptop, I considered the most recent one, where the Python script was installed => I tested the Alina’s script with Notepad++ v7.6.3 !

As this version is located in D:\@@\763\... :

First, I created a folder named D:\@@\763\Test
Then I created two ANSI files, in folder Test
I opened N++ v7.6.3 and the Python console
I used the Python script, below which worked as expected : The two files, in the Test folder, have been saved with the new UTf-8 encoding, without any trouble !

import os;
import sys;
import Npp;
from Npp import notepad

filePathSrc="D:\\@@\\763\\Test" # Path to the folder with files to convert

for root, dirs, files in os.walk(filePathSrc):
    for fn in files:
        if fn[-4:] == '.txt':
             notepad.open(root + "\\" + fn)
             console.write(root + "\\" + fn + "\r\n")
             notepad.runMenuCommand("Encoding", "Convert to UTF-8")
             notepad.save()
notepad.close()

and after executing the script, it wrote, on console :

Python 2.7.15 (v2.7.15:ca079a3ea3, Apr 30 2018, 16:22:17) [MSC v.1500 32 bit (Intel)]
Initialisation took 125ms
Ready.
D:\@@\763\Test\File_1.txt
D:\@@\763\Test\File_2.txt

As you can see, in the script :

Of course, I just changed the value of the variable filePathSrc
I also changed the line :

         notepad.runMenuCommand("Encoding", "Convert to UTF-8 without BOM")

by the line :

         notepad.runMenuCommand("Encoding", "Convert to UTF-8")

This detail supposes that @alina-gubanova is using, a very old version of N++ ;-))

Best Regards,

guy038

dail · Jun 20, 2019, 7:52 PM

@Alina-Gubanova How are you launching the script? Inside of Notepad++?

Alina Gubanova · Jun 20, 2019, 7:56 PM

@dail yes.
So these are my steps:
Run -> Python (where I saved C:…\Python2.7\Lib\idlelib\idle.py “$(FULL_CURRENT_PATH)”) -> IDLE opens up in a new window -> press F5 -> Traceback (most recent call last): File "C:\Users\agubanova\Notepad++\plugins\PythonScript\scripts\new script.py", line 3, in <module> import Npp; ImportError: No module named Npp

Alina Gubanova · Jun 20, 2019, 7:58 PM

@guy038 thank you so much for putting your time in such a detailed explanation. I should definitely update my N++ version :)
I followed every step of your explanation, and I still get an error. When you Run the script what is the directory that you use?

I suspect mine could be wrong. Is it C:…\Python2.7\Lib\idlelib\idle.py “$(FULL_CURRENT_PATH)” ?

You could have said that in the beginning and saved some time. You can’t run a Pythonscript that way. It isn’t going to know about the special “notepad” objects. You have to run it from the Pythonscript menu, as I said earlier.

Hi, @alina-gubanova,

Before, describing the tree structure of my D:\@à\763 folder, note two points :

The install folder of a portable N++ version must be different from, either, C\Program files and C\Program files (x86)
Any local installation of Notepad++ needs the zero-length file, doLocalConf.xml, along with the executable notepad++.exe

This file, installed by default, assures you that any file created and/or handled by Notepad++, will be located inside the installation folder ;-))

Depending of your system, follow one of these links, below, to download the last portable N++ v7.7.1

https://notepad-plus-plus.org/repository/7.x/7.7.1/npp.7.7.1.bin.zip

https://notepad-plus-plus.org/repository/7.x/7.7.1/npp.7.7.1.bin.x64.zip

Just create any folder in your system and extract the contents of the archive in this folder !

On the other hand, I’m using the PythonScript v1.3.0.0 ( PythonScript_Full_1.3.0.0.zip ) but you’ll find the latest release v1.4.0.0 , below :

https://github.com/bruderstein/PythonScript/releases

Note that, from N++ version v7.6 and above, there’s a new organization of plugins, in the Plugins folder. From now on, any plugin, let’s say myFirstPlugin.dll, must be moved inside a folder named the same way, so myFirstPlugin !

OK, as promised, here is the tree structure of my D:\@@\763 folder :

@Alan-Kilborn I apologize for the confusion. Followed the steps that were suggested by a coworker, so wasn’t aware of the issue. I’ll try running it that way. Thank you for your time

Alina Gubanova · Jun 20, 2019, 9:17 PM

@guy038 thank you so much for putting time into this and offering some useful advice! I’ll make sure to follow the steps and let you know!

Yes, except technically the OP was launching it from within Notepad++. But…there are degrees of within, and when you are wanting to do operations with Python tight to the Scintilla and Notepad++ cores (the original script used the notepad object), you have to be REALLY within. :)

Run menu : sorta within, but mostly not because it is just telling Notepad++ to launch an external process
Pythonscript menu : really within, because it is using the Python interpreter part of the plugin (and can access the editor (Scintilla) and notepad (N++) objects.

And @dail, I know you know all this … I write it for the edification of other readers. :)
