Style token not saved

Alan Kilborn

Hmm, at this point, I’m not sure.

Does the Notepad++ status bar indicate that your file’s encoding is UTF-8?

I just tried the script as written above in a fresh setup of N++ v8.4.7 and PythonScript v3.0.12, as well as also trying it with PS v2.0, and the script ran fine, either with or without the new first line I asked you to add.

Aside from having you examine your copy of the script file in a hex editor, to see if somehow an oddball character has crept in (at the position indicated by the error message), I’m not sure what else to do here.

Maybe @PeterJones has an idea?

yep, I checked it now, it is setted on: Format -> Coding in UTF-8.
However, I explain the step that i’m doing, probably I wrong something:

This is the path where the script is located : C:\Program Files\Notepad++\plugins\Config\PythonScript

In this path I putted also a file called styling.txt

I’m using Python 3.10 to run the script.

As long as you can see the script when you go here in the N++ menu (as you need to do to run it), the location of the script should be fine:

In this path I putted also a file called styling.txt

Well the script puts that file there, not you. So I don’t think knowing this gets us anywhere with the debugging.

It works now, I see the windows of the script.
Click on yes, the script should save the style token, but when I close and reopen the file .txt the style token of the file is disappear.

GREAT!

but when I close and reopen the file .txt the token style of the file is disappear

Are you running the script again, and choosing No this time?

I’m doing these steps:

I put a style token on a word.
Run the script and click on YES.
Close and Reopen the file .txt
I don’t see the style token, I Run the script again and click on NO.

After step 4 I see the text without style token.

The problem can be due to the Notepad++ version?

BallardiniFANS

Update: I tried with the v8.1.9.2, but nothing changes.

@Alan-Kilborn Have you any idea? Is it work in your environment?
Let me know, this function is fundamental for me eheh.

Alan Kilborn

@BallardiniFANS

Yes, it works fine for me. I would have mentioned it if it didn’t.

I’m sort of out of ideas on why it isn’t working for you.

It might be nice to have some independent verification from others that the script works fine for them. @PeterJones maybe?

You could certainly try the script with a newer version of Notepad++ than 8.1.* and see if that makes a difference.

BallardiniFANS

@Alan-Kilborn
There is an error when I choose YES or NO:

BallardiniFANS

Now it works fine!!!
Running Notepad as administrator the issue is fixed.

Thank you very much @Alan-Kilborn

Alan Kilborn

@BallardiniFANS

OK, with the more detailed error reporting I can see what failed with the script. While running as administrator solves the problem, it is rather like cutting off your arm because you have a hangnail – problem solved, but…

Note that I believe the intent of the script was just to demo the functionality, not really be useful in a general sense. Why do I say this? Because a single file is used for the data, it is only useful with a single source file. (There are some other logistical problems with saving and restoring styling, as well).

Let me rework the script a little, I’ll post a new one here; check back here in a few days…

Alan Kilborn

It appears I didn’t give the original script a name in this thread, although I called it StylingSaveOrLoad.py on my setup. Thus, for a new script, I’ll call it StylingSaveOrLoad2.py.

The new script is similar to the old, but a major way it is different is that it saves a .sty file in the same folder as the original file, to hold the styling data. Thus, if you’re editing test.txt and then save the styling by running the script, you’ll see test.sty in the same folder.

You can directly invoke this script, to get a prompt box much like the original script:

Or, if you prefer, you can set two up new keycombo-invoked scripts, such that one directly saves the data file, and one applies the styling from the data file (i.e., loads it).

If you like the two-keycombo approach, here’s how to set up the additional scripts needed for that:

Add these lines to (user) startup.py:

import StylingSaveOrLoad2
ssol2 = StylingSaveOrLoad2.SSOL2()

Create a new script file called StylingSaveForCurrentFile.py with content:

# -*- coding: utf-8 -*-
ssol2.save_data_file()

Create a new script file called StylingLoadForCurrentFile.py with content:

# -*- coding: utf-8 -*-
ssol2.load_data_file()

Bind the running of these two scripts to keycombos of your choosing

@Alan-Kilborn Works!!! I don’t use notepad++ to develop code, only to create content for my websites, and that helped me a lot, thank you very much.

nsk7even

@Alan-Kilborn thank you for this great script! I tried it and it works kind of.
Interestingly I have to run the script multiple times to let it apply (load) all word highlightings for a style token.
It seems to be arbitrary how much occurrences of the word that is to be styled are missing.

Do you have an idea of the reason of this behaviour?

I can see the same thing; currently I don’t know why it is happening. :-(

hi I followed your guide it works perfect thank u.
but I dont know how can bind keys to those scripts.
can u help me with that?
sorry for necro if it is not allowed
