    Strange - works for me.
    Could it be that you already have some ctypes based code in startup.py ?
    Variable overwriting?
    May you share your startup.py ?
    Or maybe comment everything except the LTR code if you have already ctypes code.

    Cheers
    Claudia

      Claudia,

      Strange - works for me.

      Do you mean the output is RTL when you open the console?

      I’ve removed my other code for testing it.

      Actually I don’t need it on startup. I can write a “Show Console” script.

      Thank you.

        yes, on my side it is.

        When I run a second time from my test script it doesn’t change until
        another write statement happens, then it is back to LTR.

        Cheers
        Claudia

          Interesting.

          I missed that. Sorry.

          # The lines up to and including sys.stderr should always come first
          # Then any errors that occur later get reported to the console
          # If you'd prefer to report errors to a file, you can do that instead here.
          import sys
          from Npp import *
          
          # Set the stderr to the normal console as early as possible, in case of early errors
          sys.stderr = console
          
          # Define a class for writing to the console in red
          class ConsoleError:
          	def __init__(self):
          		global console
          		self._console = console;
          
          	def write(self, text):
          		self._console.writeError(text);
          
          # Set the stderr to write errors in red
          sys.stderr = ConsoleError()
          
          # This imports the "normal" functions, including "help"
          import site
          
          # This sets the stdout to be the currently active document, so print "hello world",
          # will insert "hello world" at the current cursor position of the current document
          sys.stdout = editor

            On my machine it changes immediately. It’s gibberish until writing again.

            Thanks.

              Yaron,

              strange - might be linux/windows related.
              I’ve copied your startup.py - cleaned mine (commented everything)
              and now I have your behavior. Phew …

              Yaron, it is already half past 4 here and I have to go to late shift today.
              Need to have some sleep ;-) I will follow up on this in ~16 hours.
              Maybe earlier if we don’t have to do much at work and I can have look.

              Good night.
              Cheers
              Claudia

                Claudia,

                Thank you very much. You are great!

                default

                Sorry for keeping you up so late.
                Sleep well and have a nice day. :)

                  Thank you :-D

                  Did some last test - looks like it a
                  console.show()
                  before the code
                  and if you wish
                  console.hide()
                  afterwards does the trick.

                  Good night.

                  Cheers
                  Claudia

                      Yaron,

                      did try to understand what the difference could be but …
                      While investigating the python script code I assume I found what needs to be changed in
                      order to force a LTR layout.

                      The file StaticDialog.cpp has a function makeRTLResource.
                      Within the function there is this if condition

                      if (pMyDlgTemplateEx->signature == 0xFFFF)
                      	pMyDlgTemplateEx->exStyle |= WS_EX_LAYOUTRTL;
                      else
                      	(*ppMyDlgTemplate)->dwExtendedStyle |= WS_EX_LAYOUTRTL;
                      

                      what about giving a try to use

                      if (pMyDlgTemplateEx->signature == 0xFFFF)
                      	pMyDlgTemplateEx->exStyle;
                      else
                      	(*ppMyDlgTemplate)->dwExtendedStyle;
                      

                      Yaron, sorry, I would love to see why our machines behave differently but without a debugging environment it’s hard to track down the issue maybe this little code change is a better alternative.

                      Cheers
                      Claudia

                        I apologize for not being clear enough in my last post.
                        In “Very nice” I meant to confirm the issue was solved by adding console.show(). :)

                        Thank you very much for that too.
                        A couple of years ago Dave uploaded a PythonScript v1.1.1 without committing the changes.
                        As your script works perfectly, I’d rather keep using v1.1.1.

                        Many thanks again for your kind help. I do appreciate it.

                        Best regards.
