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

      How should this work? A fold flag doesn’t know if it is set for the header tag or something else.
      Of course you could anaylze the code for the head tag but how should teh script know
      which scripts you want to have collapsed and which expanded?

      Cheers

      It would “click” the + that is on a specified line or the line were the flag is.

        No, this is not what I meant.
        Let’s assume we have the following code

        <!DOCTYPE html>
        <html>
            <head>
                <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>
                    function func_b1() {
                        document.getElementById("b1").innerHTML = "Or Should I be collpased?";
                    }
                </script>
            </body>
        </html> 
        

        How should a script decide which of the script tag needs to be collapsed?
        There must be some logic provided by you to collapse the correct tag.

        Cheers

          .

          <!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>

              <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

          1.<!DOCTYPE html>
          2.<html>
          3.<head>       <!-- NPP_PLZ_COLLAPSE_THE_LINES(3,21) -->

          5.        function func_h1() {
          6.            document.getElementById("h1").innerHTML = "Should I be collapsed?";
          7.        }
          8.    </script>
          9.</head>
          10.<body>
          11.
          12.    <h2>JavaScript Example</h2>
          13. 
          14.    <p id="h1">Head1</p>
          15.    <p id="b1">Body1</p>
          16.
          17.    <button type="button" onclick="func_h1()">Head1</button>
          18.    <button type="button" onclick="func_b1()">Body1</button>
          19.
          20.
          21.    <script>
          22.        function func_b1() {
          23.            document.getElementById("b1").innerHTML = "Or Should I be collpased?";
          24.        }
          25.    </script>
          26.    <script>
          27.        function func_b1() {

          29.        }
          30.    </script>
          31.</body>
          32.</html> 
          

          It would collapse the lines 3 and 21 because of “NPP_PLZ_COLLAPSE_THE_LINES(3,21)”.

            ok, let’s finalize it.
            The folding logic is the following

            Searching 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?

            Cheers
            Claudia

                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 folding

                      Within 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\((\d+,\d+)\)'
                      
                      # -----------------------------------------------------------------------------

                      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.

                              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.

                                sorry - I forgot one step.

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

                                Cheers

                                  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

                                      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.

                                        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
