      @pallieguy said in Notepad++ 8.4.2 not recognizing file extension to define language:

      and called it demo.php
      When I open it it’s still user defined.

      When you are saying “open”, do you mean “when I launch Notepad++ and the saved session includes demo.php” or do you mean “when I close demo.php and then use File>Open or equivalent to open the demo.php, it still says it is user defined”

      Because if you manually selected “user defined” (either intentionally or on accident) for demo.php and exit Notepad++ without closing, and if you have “remember current session for next launch” enabled, then when Notepad++ writes the session.xml file, it saves the UDL that you had assigned to an open file. Until you actually close the file before exiting Notepad++, the application will continue to remember your manual UDL choice.

        Mandalore is what my computer is named. Your pun made me laugh out loud and my Girlfriend called me a nerd.

        When I close demo.php and go File > Open or double click on the file in my Windows Explorer window (N++ is my default) then the language is not identified. If I launch notepad any saved sessions keep the language I’ve identified.

        Under Language > User Defined Language > Define Your Langauge… I see the following:
        04737a10-fe50-4c96-a12f-8be8114795d4-image.png

        I thought I might have clicked something, but I’m trying brand new files and they’re not doing it.

          Okay, so I jsut tried opening a CSS file and it recognized it as CSS and now my php files are being recognized. I’m not sure if it was opening the User Defined Languages popup or opening the CSS file, but something in there fixed my issue.

          Strange…

            Indeed, that is the way it works. The session files track the Language selected for each file – so that way if you’ve manually selected a language for a file, it will keep it from run-to-run as long as you don’t close the file in Notepad++. And if you had saved a separate session file (File > Save Session…) then that UDL information was saved in that file, so any time you load that session file, it will keep that UDL information with the file. Other *.php files, and any file like the php.misnamed which starts with <?php will determine the type as PHP when you do the File > Open on them; but if you have a PHP file in a session and had saved that session with something other than PHP selected, it will remember that. Resave your session now that demo.php is identified as a PHP, and your problem will not come back to haunt you.

              Hello

              I recently had a similar “issue” with other type of source files and only if I open the file from file explorer and not from File->Open.

              For example .py, .md, .txt, .json, etc. files (with extension).
              When they are opened from File->Open or File->Recent the language is detected and is correctly visible on the left side of status bar.
              When they are opened from file explorer in all cases the language is not detected and in status bar is see the following a21361f7-3023-4355-817c-aba89919657f-image.png

              I have a couple of UDLs but all mentioned file types-extensions should not be affected.

                @giannis-raptis ,

                Given that your status bar shows path or file/machine information in the “file type” section like @Pallieguy showed, I now think you have found something… however, I am not able to replicate it with my installation of Notepad++.

                If I use the Windows Explorer and use the double-click action (on file types like .txt and .md, which have their default action set to Notepad++), it loads them up and immediately recognizes the type; and if I use my right-click Edit with Notepad++ action on any file type (those listed, or .py or .json, to finish replicating your examples), it also correctly recognizes the type: it does not pick a non-existent UDL and show part of the file path in the status bar.

                I wonder if there’s some difference in the way our file associations are defined which are causing the difference between your installation’s behavior and mine… Weird. If you can provide more information (how you made your associations, or digging into the registry to show us exactly what those associations look like), it might provide enough hints to make a replicable situation: if we can replicate it and define the exact sequence of events necessary, then we can probably file a bug report about it; but without a way to replicate it, I am not sure that a bug report will get much activity after the first attempt to replicate it fails.

                  I booted up my computer today and I’m now getting the behavior described by @Giannis-Raptis. If I go File > Open it detects the language, if I right click in explorer and select Edit with Notepad++ it detects the language, if I select the file from the recent files section under the File menu it detects the language. The only way it doesn’t is if I double click the file in Windows Explorer.

                  I’ve tried my hardest to avoid dealing with the windows registry. If you can let me know what details you need I’ll gladly get you what I can.

                    Here’s a way to do it where you cannot accidentally write anything: using the command-line REG QUERY which just grabs information from the registry without editing it. (For these instructions, I am assuming that even double-clicking a *.txt file is giving this wrong behavior. If not, replace the .txt below with an extension that double-clicks into Notepad++ but doesn’t identify correctly, like maybe .php, since that’s what started it all.)

                    Open a command prompt

                    REG QUERY HKCR\.txt /VE
                    

                    This will output something like:

                    HKEY_CLASSES_ROOT\.txt
                        (Default)    REG_SZ    txtfile
                    

                    Whatever the text is to the right of REG_SZ, use that in the next query:

                    REG QUERY HKCR\txtfile
                    

                    Share those results with us (use the </> button on the forum toolbar to wrap your text in a black box like I did)

                    For example, mine is:

                    C:\usr\local\share>REG QUERY HKCR\.txt /VE
                    
                    HKEY_CLASSES_ROOT\.txt
                        (Default)    REG_SZ    txtfile
                    
                    
                    C:\usr\local\share>REG QUERY HKCR\txtfile
                    
                    HKEY_CLASSES_ROOT\txtfile
                        (Default)    REG_SZ    Text Document
                        EditFlags    REG_DWORD    0x210000
                        FriendlyTypeName    REG_EXPAND_SZ    @%SystemRoot%\system32\notepad.exe,-469
                    
                    HKEY_CLASSES_ROOT\txtfile\DefaultIcon
                    HKEY_CLASSES_ROOT\txtfile\shell
                    

                    Those will give the “old fashioned” file associations, which Windows used prior to Win10 (and still work in Win10 and Win11, though they are moving away from them)

                    But since @giannis-raptis is on Win10, it might be useful to examine the newer “Open With” storage locations

                    REG QUERY HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.txt /S
                    REG QUERY HKCR\Applications\notepad++.exe /S
                    

                    Give us the output to both of those as well

                    For the record, mine are:

                    C:\usr\local\share>REG QUERY HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.txt /S
                    
                    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.txt\OpenWithList

                    HKEY_CLASSES_ROOT\Applications\notepad++.exe\shell
                    
                    HKEY_CLASSES_ROOT\Applications\notepad++.exe\shell\open
                        Icon    REG_SZ    c:\usr\local\apps\notepad++\notepad++.exe,-101

                    And finally, grab

                    REG QUERY HKCU\Software\Microsoft\Windows\CurrentVersion\ApplicationAssociationToasts
                    

                    But that’s too big. So paste it into Notepad++, and then run the following replacement on it:

                    • FIND WHAT: (?-s)^((?!Toasts|Notepad\+\+\.exe|\.txt).)*(\R|\Z)
                    • REPLACE WITH: (empty)
                    • hit Replace All

                    Then copy/paste the filtered results from Notepad++ into a black </> box in your your reply as well.

                      I tried a .txt to see if the language problem persisted and like after the .css yesterday, the language is back to being detected properly for all my files. If it happens again tomorrow I will run these commands and post them while it’s still wonky.

                      First set of commands:

                      C:\Users\Palli>REG QUERY HKCR\.php /VE
                      
                      HKEY_CLASSES_ROOT\.php
                          (Default)    REG_SZ    php_auto_file
                      
                      
                      C:\Users\Palli>REG QUERY HKCR\php_auto_file
                      
                      HKEY_CLASSES_ROOT\php_auto_file\shell
                      

                      Second two:

                      C:\Users\Palli>REG QUERY HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.php /S
                      
                      HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.php\OpenWithList
                          a    REG_SZ    firefox.exe

                      HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.php\UserChoice
                          Hash    REG_SZ    8c5Dq+bAc2A=

                        @pallieguy ,

                        I wonder if one of your plugins is causing Notepad++ to have intermittent difficulty in identifying the file type. Weird. If it goes back to happening, share your ?-menu’s Debug Info like @Giannis-Raptis did.

                        Also, if it happens again, try closing Notepad++ and renaming your c:\program files\notepad++\plugins directory (which is one of the steps in this FAQ, which though it claims to be about crashing, is also a general-purpose see-if-plugin-is-causing-problem instruction set; because your problem is only with double-click, you cannot easily use option #1, but option #2 will still work for you)

                            I haven’t installed any plugins that I’m aware of, but I’ll try that after posting if it happens again tomorrow.

                            Debug info:

                              @pallieguy said in Notepad++ 8.4.2 not recognizing file extension to define language:

                              I haven’t installed any plugins that I’m aware of

                              Your Debug Info agrees: you only have the default plugins, which aren’t the culprit.

                              Well, let us know if the problem comes back.

                                Day three and the same problem. Only difference is I didn’t shut down the computer last night.

                                First commands:

                                C:\Users\Palli>REG QUERY HKCR\.php /VE
                                
                                HKEY_CLASSES_ROOT\.php
                                    (Default)    REG_SZ    php_auto_file
                                
                                
                                C:\Users\Palli>REG QUERY HKCR\php_auto_file
                                
                                HKEY_CLASSES_ROOT\php_auto_file\shell
                                

                                Second Set:

                                C:\Users\Palli>REG QUERY HKCR\Applications\notepad++.exe /S

                                Possible solution
                                I find out that if N++ is closed and I open the file through Windows Explorer, then language is detected and everything works, even if I open new files. If I open N++ from my taskbar shortcut (Set by right clicking an open N++ and selecting Pin to taskbar) then double click on the file in Windows Explorer is the only time it seems to not be working. Opening N++ by opening the file in my taskbar also shows a second N++ icon in that taskbar:

                                Unpinning the old shortcut (originally pinned so long ago I don’t recall which N++ version it was) and pinning the new one Fixed the problem entirely. It may be that enough time has passed for the problem to resolve itself like when I tried the txt and css files, so I’ll have another update tomorrow, but it appears the issue had to do with the shortcut made for an older version of N++.

                                  I missed the edit window to correct this, sorry.

                                  Before my taskbar screenshot I meant to say:

                                    Yeah. I wonder if you still have a residual notepad++ installation somewhere else other than your newly-pinned shortcut.

                                    Actually, your data actually already shows that. Earlier, you were running from C:\Program Files\Notepad++\notepad++.exe, as your Debug Info showed. Your REG QUERY output showed

                                    HKEY_CLASSES_ROOT\Applications\notepad++.exe\shell\open\command
                                        (Default)    REG_SZ    "D:\Notepad++\notepad++.exe" "%1"
                                    

                                    (though I didn’t see it yesterday, because I didn’t scroll far enough in your black box)

                                    So when you double-click when no notepad++ was running, it ran your D:-drive copy of Notepad++. If you used your old shortcut, it was apparently running your C:-drive copy … and then, because you presumably don’t have multi-instance enabled, when you double clicked, it tried to run the D:-drive copy, but saw the C:-drive copy running and opened the file with that instead.

                                    Since I believe you pinned the copy that was associated, I believe your pin should now point to the D:-drive copy. If so, I would recommend removing the C:-drive copy, to avoid future confusion. But check your pin to make sure: right click on the pin, then right click on the notepad++ near the bottom, then select “properties”: the Target field will show which one is now pinned.

                                      I do indeed have a C: and a D: install, I wonder when I did that?

                                      Glad this is resolved, thanks fro all your help!

                                        Probably at one of the updates: there was a while when the installer would not notice an old installation if it wasn’t in c:\program files\notepad++, so even if you had installed to D:\notepad++\, the updater/installer would put the newer copy in c:\program files\notepad++ instead. IIRC, that has been fixed (I spent a couple minutes searching through the issues list, but wasn’t using a narrow enough set of search terms, so couldn’t find it buried in all the other results), so the next time you run the installer/updater for whatever version you end up keeping, it should hopefully default to the existing location.
