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

.
<!DOCTYPE html> <html> <head> <!-- NPP_PLZ_COLLAPSE_THIS_LINE --> <script> function func_h1() { document.getElementById("h1").innerHTML = "Should I be collapsed?"; } </script> </head> <body> <h2>JavaScript Example</h2> <p id="h1">Head1</p> <p id="b1">Body1</p> <button type="button" onclick="func_h1()">Head1</button> <button type="button" onclick="func_b1()">Body1</button> <script> // NPP_PLZ_COLLAPSE_THIS_LINE function func_b1() { document.getElementById("b1").innerHTML = "Or Should I be collpased?"; } </script> <script> function func_b1() { document.getElementById("b1").innerHTML = "Or Should I be collpased?"; } </script> </body> </html>It would then “click” on the - that is on the right of the number of the lines that contains “NPP_PLZ_COLLAPSE_THIS_LINE” (btw when I said “+” above in a post I meant “-”).
OR

ok, let’s finalize it.
The folding logic is the followingSearching through the document to find either the identifier to collapse
the fold header in this line or the identifier to collapse every root fold header starting
from A to (including) Z.In the case of folding A to Z the identifier is immediately followed by the start and end line separated by a comma and encased by round parenthesis.
In any case only this level will be folded so if clicking onto the plus sign
the whole structure gets expanded again.Program logic is,
whenever a file gets activated first it gets scanned about the identifiers and
the parts get collapsed. If a file gets closed and reopened the logic will be applied again.
If only the buffer is switch, meaning you switch from one tab to another one
nothing happens.Do you agree?

ok - I don’t find the time today but I will provide a possible solution tomorrow.

I have a similar problem.
I wrote a script that solves it, but I can’t make it work properly in FILEOPENED callback.
This works just fine.from Npp import * # Collapses all blocks annotated with "//!" def auto_collapse(): to_collapse = []; for i in range(0, editor.getLineCount()-1): line = editor.getLine(i).strip() if line[:3] == "//!": to_collapse.append(i+1) for num in to_collapse: editor.foldLine(num, 0) auto_collapse()But this script behaves buggy as hell (no errors, just incorrect folding). Why? Maybe there is another “FILEREADY” callback to hook on?
from Npp import * def auto_collapse(args): notepad.activateBufferID(args["bufferID"]) to_collapse = []; for i in range(0, editor.getLineCount()-1): line = editor.getLine(i).strip() if line[:3] == "//!": to_collapse.append(i+1) for num in to_collapse: editor.foldLine(num, 0) notepad.callback(auto_collapse, [NOTIFICATION.FILEOPENED]) -
Okay, now THIS works for me. It seems like that dirty hack with “new/close” forces N++ to repaint the folded document. Now I’m searching for the best way to launch this on N++ startup.
from Npp import * def auto_collapse(args): notepad.activateBufferID(args["bufferID"]) for i in range(0, editor.getLineCount()-1): line = editor.getLine(i).strip() if line[:3] == "//!": editor.foldLine(i+1, 0) notepad.new() notepad.close() notepad.callback(auto_collapse, [NOTIFICATION.FILEOPENED]) -
Ok, this wasn’t as straightforward as I thought it is, basically because
the folding flags get set after buffer has been activated, therefore
I’m using now UPDATEUI callback, with some logic to prevent multiple scans, to do the foldingWithin the configuration area you can define which file extensions
should be handled. COLLPASE_LINE_IDENTIFIER and COLLPASE_FROM_TO_IDENTIFIER
can be changed as long as the changes do not break regex searches.
In addition for COLLPASE_FROM_TO_IDENTIFIER matches need to be in form any_numberCOMMAany_number (like 3,4 or 14,25).In order to make this work automatically, meaning that the script gets called when npp starts,
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)
and copy the content into it. Restart npp and test it.If you do it like that then the logic is the following:
When starting npp, the script gets executed and registers two callbacks.
The BUFFERACTIVED callback gets called whenever you switch to another tab,
then the function checks if this file should be folded and if so if it has been already done.
If it hasn’t be done it set a global flag that it needs to be done.
The second callback UPDATEUI is called whenever something changes within the current document,
if the flag has been set that the document should be scanned, it will do so, collapses
the found lines and set the global flag to false in order to prevent subsequent scans.import os # ---------------------------- configuration area ----------------------------- FILE_EXTENSION_LIST = ['.html','.js'] COLLPASE_LINE_IDENTIFIER = 'NPP_COLLAPSE_IT' COLLPASE_FROM_TO_IDENTIFIER = 'NPP_COLLAPSE\((\d+,\d+)\)' # ----------------------------------------------------------------------------- def scan(number_of_lines): def find_line_identifiers(): # NPP_COLLAPSE_IT matches = [] editor.research('\\b{0}\\b'.format(COLLPASE_LINE_IDENTIFIER), lambda m: matches.append(m.span()), 0) return matches def find_from_to_line_identifiers(): # NPP_COLLAPSE(19,41) matches = [] editor.research('{0}'.format(COLLPASE_FROM_TO_IDENTIFIER), lambda m: matches.append(m.span(1)), 0) return matches for match in find_line_identifiers(): _line = editor.lineFromPosition(match[0]) if editor.getFoldLevel(_line) & FOLDLEVEL.HEADERFLAG: editor.foldLine(_line,0) for match in find_from_to_line_identifiers(): start_line, end_line = list(map(lambda x: int(x)-1, editor.getTextRange(*match).split(','))) while True: if start_line <= end_line: if editor.getFoldLevel(start_line) & FOLDLEVEL.HEADERFLAG: editor.foldLine(start_line,0) start_line = editor.getLastChild(start_line,-1) + 1 else: start_line += 1 else: break should_be_folded = False def callback_FOLD_BUFFERACTIVATED(args): 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 elif _state == '-1': should_be_folded = False def callback_FOLD_UPDATEUI(args): global should_be_folded if should_be_folded: scan(editor.getLineCount()) should_be_folded = False notepad.callback(callback_FOLD_BUFFERACTIVATED, [NOTIFICATION.BUFFERACTIVATED]) editor.callback(callback_FOLD_UPDATEUI, [SCINTILLANOTIFICATION.UPDATEUI])Did only some basic tests, but hope this is useful for you.

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

Where do I find/put that?
-
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.Cheers
Claudia -
sorry - I forgot one step.
before you restart npp, goto
Plugins->Python Script->Configuration
and instead of Initialisation: LAZY choose ATSTARTUP.Cheers
Claudia -
@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). -
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.Cheers

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.
-
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.Cheers

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

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.dllIn 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.

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\scriptsConcerning the print statement - a standard python script installation has has the following
entry in the standard startup.pysys.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 thissys.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
Claudia
