Is there a way/plugin that makes notepad++ run code on a file when we open it?

Claudia Frank

call the script from user startup.py or put your code into user startup.py.

create a new script and name it startup.py (if you not already have a user startup.py - not to be confused with the standard startup.py python script automatically created)

Where do I find/put that?

Claudia Frank

@Alguem-Meugla

either install python script plugin via plugin manager or by using the msi package.
I would suggest to use the msi package as it has been reported that installation via plugin manager
fails from time to time.

Once installed, goto Plugins->Python Script->New Script and name it startup.py.
and press Save button.
Copy the posted script into the newly created document, save it and restart npp.

@Alguem-Meugla

sorry - I forgot one step.

before you restart npp, goto
Plugins->Python Script->Configuration
and instead of Initialisation: LAZY choose ATSTARTUP.

Cheers
Claudia

Alguem Meugla

@Claudia-Frank
I copied the script to Plugins>Python Script>Scripts>(Ctrl+)startup and saved as administrator.
I also did what you said on Configuration.
But it is doing nothing when I start my file with “NPP_COLLAPSE_IT” on a line with a -. I then changed the script and added a line “print(‘startup.py done!’)” on the end trying to see if Plugins>Python Script>Show Console showed it, but nothing appears there other than Ready (and some more things above it).

Claudia Frank

@Alguem-Meugla

I don’t understand what you mean by

I copied the script to Plugins>Python Script>Scripts>(Ctrl+)startup and saved as administrator.

you should have done

goto Plugins->Python Script->New Script and name it startup.py
and press Save button.
Copy the posted script into the newly created document, save it and restart npp.

Depending on your installation, the script directory is different,
by using the way I mentioned you make sure that the correct directory is used.

When I go on New Script it puts me on Documents. Should I create the file there or in a place I want? I had created a folder there and put the new file named startup.py with the script inside it, but wasn’t working, so I replaced the standard startup.py with the new one. Didn’t work.

Claudia Frank

@Alguem-Meugla

yes, you should save it in the default directory, the one which
get opened by using New Script.

The standard startup.py is used do the general setups and initialization.
I do not recommend to modify this file as long as you know what you do.
I hope you do have a copy of the old one and you can revert your changes.
If not, a reinstall of the python script plugin is needed I guess.

I think that there is not a place which any plugin/program can trust. When I use New Script it opens to me the directory I left the dialog on the last time, MyDocuments\Python Notepad++ (the folder I created).

After reinstalling the plugin and having the default startip.py back, I tried having a copy of the new startup.py on MyDocuments, another on MyDocuments\Python Notepad++, and another on %APPDATA%\Notepad++\plugins\config\PythonScript\scripts (the plugin’s Help said it was the User directory). All those copys should also print some words after your script. After restarting N++ it doesn’t print anything neither collapse the line it should (https://image.prntscr.com/image/Wa9pMODERIm7Kq7cnHhZAg.png).

I also tried having one copy on the same folder as the Samples folder and the default startup.py (inside a folder I created so it didn’t have problems with 2 startup.py’s). After restarting N++ nothing happened, but it was appearing on the Scripts list so I clicked it and: no collapse and the print worked (this means the script is not collapsing for some reason, maybe because it’s not happening at startup?).

Thank you for the help and time you are giving to this.

Can you post your debug->info (available under ? menu?

In addition, what do you see if you run the following code

notepad.getVersion()

in the python script console, like here

Cheers
Claudia

Here it is:
Notepad++ v7.4.2 (32-bit)
Build time : Jun 18 2017 - 23:34:19
Path : C:\Program Files (x86)\Notepad++\notepad++.exe
Admin mode : OFF
Local Conf mode : OFF
OS : Windows 10 (64-bit)
Plugins : JSMinNPP.dll mimeTools.dll NppConverter.dll NppExec.dll NppExport.dll NppFTP.dll NppTextFX.dll PluginManager.dll PythonScript.dll ReloadButton.dll

In addition, what do you see if you run the following code

notepad.getVersion()

in the python script console, like here

It returns:
(7, 4, 2)

Definitely version 7.4.2.

Claudia Frank

@Alguem-Meugla

Ok, the command was to see if the python script plugin works in general and
the debug info shows, that two directories are of interest in regards to automated startup.

The standard startup.py, the one which is automatically created during installation
should be located under C:\Program Files (x86)\Notepad++\plugins\PythonScript\scripts\

The user startup.py, the one you should have created should be located under
%APPDATA%\Notepad++\plugins\config\PythonScript\scripts

Concerning the print statement - a standard python script installation has has the following
entry in the standard startup.py

sys.stdout = editor

This means, that a print … will not be send to the console but to the currently active document.
In order to change this behavior you need to modify it like this

sys.stdout = console

and restart npp. Now a print statement would be send to console.

In addition, there should be a file %APPDATA%\Notepad++\plugins\config\PythonScriptStartup.cnf.

Can you post its content?

Cheers

I don’t know python (i only learnt the first lessons of it on codecademy), so I didn’t know if print was supposed to write on the console or in the file. First I thought it was on the console so I was always opening it to see if there was something. But when I tested the script on the same folder as the Samples and the default startup.py I found it was printing in the file. Not a problem. I have always checked in both places for the print output.

In addition, there should be a file %APPDATA%\Notepad++\plugins\config\PythonScriptStartup.cnf.

Can you post its content?

SETTING/PREFERINSTALLEDPYTHON/0 and on the next line
SETTING/STARTUP/ATSTARTUP

Claudia Frank

@Alguem-Meugla

Looks ok - do you see two startup.py if you
goto Plugins->Python Script->Scripts ?

One should have the addition (User).

If you press the CTRL key while clicking onto the user startup.py it should open as a document.

If this is the case, add the following line under the bufferactivated callback.

console.write('callback_FOLD_BUFFERACTIVATED\n')

Should look like

def callback_FOLD_BUFFERACTIVATED(args):
    console.write('callback_FOLD_BUFFERACTIVATED\n')
    global should_be_folded
    _state = editor.getProperty('AUTO_FOLDED')
    if _state == '':
        filename, extension = os.path.splitext(notepad.getBufferFilename(args['bufferID']))
        if extension in FILE_EXTENSION_LIST:
            editor.setProperty('AUTO_FOLDED', '1')
            should_be_folded = True
        else:
            editor.setProperty('AUTO_FOLDED', '-1')
            should_be_folded = False
    else:
        should_be_folded = False

Restart npp.

Now, every time you switch a tab you should see the line

callback_FOLD_BUFFERACTIVATED

written to the console - to prove if the script runs at all.

There’s only one at Plugins->Python Script->Scripts, the default startup.py. I can only add the new startup.py if I create a new folder like Samples or I put it inside the Samples folder:

I also have one new startup.py at %APPDATA%\Notepad++\plugins\config\PythonScript\scripts\startup.py and more at MyDocuments…
Should it appear there as a second startup.py because of this?

Restart npp.

The console outputs nothing when I switch tab, neither when I click the script (the blue startup.py above in the image).

Claudia Frank

@Alguem-Meugla

Yes, because your installation shows

Local Conf mode : OFF

this means, that notepad++ configuration files and plugin directories are located under

%APPDATA%\Notepad++

therefore, if you use Plugins->Python Script->New Script the script gets created in

%APPDATA%\Notepad++\plugins\config\PythonScript\scripts

As there is no startup.py in this directory per default you can create it and it should appear
in the same level as the standard startup.py but with the addition of (User) (done by Python Script plugin).

Please enter the following commands in the python console and post the ouput

import sys
print '\n'.join(sys.path)

New Script takes me to the last place I left the dialog on:

And I don’t have a startup.py (User) on the Scripts menu, while there’s one at %APPDATA%\Notepad++\plugins\config\PythonScript\scripts:

@Alguem-Meugla

ok, so the reason why it doesn’t work is that python script plugin
doesn’t find the startup.py but why…

Another thing which is strange, whenever I use New Script
it redirects to the user scripts directory, regardless if I created
script in another subdirectory, totally different directory or not.
Maybe this is a coincident because it can’t find the user script directory.

In addition,

C:\Users\Alguem\AppData\Roaming\Notepad++\plugins\Config\PythonScript\scripts

how could this be, mine is pointing to

C:\users\linus\Application Data\Notepad++\plugins\Config\PythonScript\scripts

Has this changed with windows 10??
May I ask how you installed python script?
Using plugin manager or the msi package I pointed to?
Which python script version did you install?
Did you somehow redirect your %APPDATA% environment variable?

When you press CTRL+R, the windows run command should open, and type
%APPDATA% and press enter, which directory gets opened and does it contain
a subdirectory notepad++??

Isn’t Application Data the same as AppData?
And %APPDATA% always redirected me to \AppData\Roaming.
What’s your windows version?

May I ask how you installed python script?

I used Plugin Manager both times, before and after I replaced the default startup.py, when I had to reinstall it.
I will try reinstalling it using that package. Plugin manager usually works right and is very simple for me.

Which python script version did you install?

It says 1.0.8.

When you press CTRL+R, the windows run command should open, and type
%APPDATA% and press enter, which directory gets opened and does it contain
a subdirectory notepad++??

CTRL+R reloads the page…
I can use WINDOWSKEY+R instead, which opens the Run window, or I can use the search menu on Windows 10. Typing %APPDATA% both opens …\AppData\Roaming\.
