UDL: /* block comment in one line, error */



  • @Gerald-Kirchner

    i’ve played around a bit with the pythonscript plugin to add/compensate this feature to the dsm4com udl and i think i got it working the way you need.

    block-comments in a single line are marked red, but all other line or block-comments are kept green.

    here is a screenshot:

    please tell us, if you need help installing or using the pythonscript plugin.

    here’s the script, to be used as pythonscript startup script:

  • @Meta-Chuh said:

    self.lexer_name = ‘udf - DSM4COM’

    this would only be returned when using notepad.getLanguageName(notepad.getLangType()) but
    the script uses windows/notepad API functions which means it should return something
    like User Defined language file - DSM4COM
    I guess you’ve already saw it but there is a little bug in the style function, as described here.



  • @Eko-palypse

    thanks, i’m not very experienced in python and the pythonscript plugin, but after your modified suffix script, i thought i give it a try and do the same for this older, unsolved thread.

    now that you are here, i have two more questions that you might be able to answer:

    why is it called udf - MyUDL if we use notepad.getLanguageName(), and not udl - MyUDL ?

    how do you kill a running pythonscript without restarting notepad++ ?



    1. Because. My guess is that at one point, it was “user defined format” or something similar in someone’s mind.
    2. Plugins > PythonScript > Stop Script


  • thanks @PeterJones

    1. at first i thought UDF was a typo while coding, but the keys L and F are too far apart for that, unless it happened when hitting the D at the edge to F, triggering both, resulting in UDFL, followed by backspacing the L instead of deleting the F.

    2. this just stops a sequentially running script, but not event handlers or callbacks like this EnhanceUDLLexer.
      is it impossible to stop those without exiting notepad++, as this event handler kind of just passes all its specs to scintilla, which processes the rest, without any further involvement of pythonscript ?



  • @Meta-Chuh said:

    1. Notepad++ internals see here
    2. High level view
      Here we have to define what a running script means.
      PS is a kind of python REPL like the standard python shell
      which runs when you start python on the commandline.
      The difference is that every script starts in a separate thread,
      but those will, if no endless loop is written, end, normally, shortly after the start.
      Callbacks are responsible that it looks like the script is still running.
      The reason is that PS (python) remembers that there are objects (callbacks) that can not yet be destroyed
      and therefore continue to live in this REPL and then be accessed by PS if necessary.
      So to “end” this script, which is already finished, completely, it is needed
      to terminate the callbacks, which means to destory its references to these objects.
      This will be done with editor/notepad.clearCallbacks methods.
      The topic is of course a lot more complex than I’ve explained briefly but basically you can say
      no matter what kind of script is started, if PS did not show up in the menu Stop Script it ended.
      If this also means that functionality is still running.

    I hope this makes sense to you.



  • I do not get Python Script in the Plugins menu.
    First installed plugin manager. Then error message when installing Python Script:
    “A file needed by the plugin manager (gpup.exe) is not present under the updater directory. You should update or reinstall the Plugin Manager plugin to fix this problem. Notepad++ will not restart.”
    Manual copy as described in PythonScript.chm did not work either.
    Then completely uninstalled and deleted all leftovers in %ProgramFiles% and %appdata%.
    npp.7.6.3.bin.x64.7z and PythonScript_Full_1.0.8.0.7z unpacked in the same directory. It does not work.



  • @Gerald-Kirchner

    unfortunately plugin installation is a little bit of a mess at the moment.
    Would you mind posting your current debug-info from ?-menu
    and in the meantime extract the PythonScript_Full_1.0.8.0.7z to a folder of your choice.

    Once we know how your current setup looks like we can give the information what needs
    to be copied/moved where to.



  • @Eko-palypse

    As described fresh portable installation.
    “npp.7.6.3.bin.x64.7z” and “PythonScript_Full_1.0.8.0.7z” unpacked in the same directory.

    Notepad++ v7.6.3 (64-bit)

    Admin mode : OFF
    Local Conf mode : ON
    OS : Windows 10 (64-bit)
    Plugins : DSpellCheck.dll mimeTools.dll NppConverter.dll



  • @Gerald-Kirchner said:

    Local Conf mode : ON

    Local Conf mode : ON tells us, that the local install directory
    is searched for the plugins and configs.

    This means, from the extracted PythonScript folder copy
    the plugins folder into D:\Daten\PortableApps\Notepad++\
    which basically asks for overwritting the plugins folder.

    The move the file PythonScript.dll from
    D:\Daten\PortableApps\Notepad++\plugins
    into
    D:\Daten\PortableApps\Notepad++\plugins\PythonScript\

    Finally copy the python27.dll from the extracted 7z into
    D:\Daten\PortableApps\Notepad++

    layout should be

    D:\
      Daten\
        PortableApps\
          Notepad++\
            plugins\
              PythonScript\

            python27.dll
    

    Restart npp and you should see PythonScript plugin in the menu



  • @Eko-palypse
    There were 2 problems.
    “\Notepad++\plugins\PythonScript.dll” instead of “\Notepad++\plugins\PythonScript\PythonScript.dll”. Wrong path packed in “PythonScript_Full_1.0.8.0.7z”.
    PythonScript is 32-bit and I had npp 64-bit.
    Solved.

    @Meta-Chuh
    I have saved the script under \Notepad++\plugins\Config\PythonScript\scripts. Initialization placed on ATSTARTUP. Click the script in the menu.
    Nothing. No red color to see. I have to learn python.
    self.lexer_name = ‘DSM_Sprache_gk_1902’ does not work too. This is the name of the imported language file.
    The configured toolbar icon is not displayed. Even the preview in “Toolbar Icons” is empty.
    With activated console and call from the menu

  • @Gerald-Kirchner said:

    PythonScript_Full_1.0.8.0.7

    overlooked this one, current version is 1.3

    error is most probably related to not having the current version installed.



  • I go to NPP -> ? -> Get More Plugins -> http://docs.notepad-plus-plus.org/index.php/Plugin_Central -> Python Script -> http://npppythonscript.sourceforge.net/download.shtml
    Latest Version 1.0.8.0
    No indication for newer versions. Please change the link to the newer version.

    Now with v1.3.0

  • May I ask you which PythonScript package you installed?



  • It looks like the minimum package does not contain the ctypes module.
    I would propose to install the full package.



  • hi @Gerald-Kirchner @Eko-palypse @PeterJones and all,
    sorry i was offline for a while.

    here is the correct guide to install the latest 1.3.0.0 pythonscript on notepad++ according to your last debug info:

    Notepad++ v7.6.3 (64-bit)
    Build time : Jan 27 2019 - 17:16:47
    Path : D:\Daten\PortableApps\Notepad++\notepad++.exe
    Admin mode : OFF
    Local Conf mode : ON
    OS : Windows 10 (64-bit)
    Plugins : DSpellCheck.dll mimeTools.dll NppConverter.dll

    • download and extract PythonScript_Full_1.3.0.0_x64.zip from >>> here <<< (do not use any other release type except this zip).

    • copy PythonScript.dll from the plugins folder of this zip to:
      D:\Daten\PortableApps\Notepad++\plugins\PythonScript\PythonScript.dll

    • copy python27.dll to:
      D:\Daten\PortableApps\Notepad++\python27.dll

    • copy the folders scripts containing machine level scripts and lib containing python libraries, from the zip’s plugins\PythonScript folder to:
      D:\Daten\PortableApps\Notepad++\plugins\PythonScript\lib\
      D:\Daten\PortableApps\Notepad++\plugins\PythonScript\scripts\

    note: for a pythonscript installation guide on your installed notepad++ version, i would need another debug info of it, as it has to be adapted acordingly.



  • PythonScript_Min_1.3.0.0 changed to PythonScript_Full_1.3.0.0. I stay at 32-bit first.
    (Also in PythonScript_Full_1.3.0.0_x64.zip the PythonScript.dll is in the wrong folder.)

    Now it works for manual execution.
    Is there a way to automate that?
    “import DSM_block-comment” in startup.py not working
    It also does not work if I write the complete code to the end of startup.py (Initialization placed on ATSTARTUP).



  • @Gerald-Kirchner

    one more thing that might be helpful to you:
    to edit startup.py or any other script from the gui, instead of searching for it in an explorer window: go to plugins > python script > scripts and hold [ctrl] while clicking on a script.



  • @Gerald-Kirchner

    Also in PythonScript_Full_1.3.0.0_x64.zip the PythonScript.dll is in the wrong folder.

    yes, all pythonscript releases have the wrong (old) folders.
    that’s why we copy the files manually to their correct locations.

    Now it works for manual execution.
    Is there a way to automate that?

    i’m glad you’ve managed to get it running as an extra user script.
    i’ll have a look at why the auto startup does not work.



  • @Gerald-Kirchner

    Now it works for manual execution.

    “import DSM_block-comment” in startup.py not working
    It also does not work if I write the complete code to the end of startup.py (Initialization placed on ATSTARTUP).

    i’ve noticed, that 1.3.0.0 has startup.py disabled by default.
    please go to plugins > python script > configuration and recheck initialisation to ATSTARTUP instead of LAZY.

    (you have already done that, but just make sure)

    after you have done that, the script should work immediately on notepad++ startup, when added eg. below the last line of the original startup.py script, as you have correctly done before, unless startup.py itself is not visible at the plugins > python script > scripts dropdown menu. we then have to recheck where it has been copied to.


    easy way to check if startup works:
    paste :

    print "hello world"
    

    below the line:

    sys.stdout = console
    

    of a default startup.py.

    the text hello world should be visible when you open the python script console.
