      Would you guys/gals either be so kind and add this in the next version of NP++

      As our Please Read Before Posting and Feature Request FAQ posts both clearly indicate, we Community members are fellow users, not the development team. No matter how many times someone mentions a cool feature in the Forum, it will never get implemented if no one puts in an official feature request.

      The UDL system doesn’t have a way to define the tab/space settings, though that would be really nice. Unfortunately, the developement team has not dealt with many/any UDL-related feature requests for years, so even if you were to follow the FAQ instructions to submit a feature request (“Allow the setting of tab width and replace-with-space on a per-UDL basis”), it is doubtful that anything would come of it.

        This file type PRG is used in Visual FoxPro/DBase as their program code files.
        I need to set the tab stops to the sire of three (3) and use spaces instead of the tab character but I see no place where I can add new extension types to the Tab Settings list.

        Aside from what Peter has said, there is a way you can change the default, so it affects every file you create from this point on, by changing the default and you do that by going to the Settings->Preferences->Languages where you’ll see this:

        Tab1.PNG

        You’ll notice I’ve already changed mine. To change yours click the checkbox for Replace by space, then click on the number next to Tab size: and you’ll see this screen:

        Tab2.PNG

        Change the tab size to the size you want and to apply it, you have to hit Enter. From then on all your tabs will be 3 spaces, but only for new documents. Any old ones will still have the old default of 4 and will be a tab character. I use dBASE Plus, so I’m a little familiar with your issues. I don’t think our languages are as similar now as they use to be, because we have a lot of differences in OOP implementation/syntax, though we have seen a number of VFP users/developers looking to move over to dBASE because of VFP development ending.

        Should you also look to change, I have developed a dBASE Plus UDL that some of our users wanted to see implemented in Notepad++, of which Peter and many here were very much instrumental in helping me get it done. I have a completed FunctionList, Autocomplete file and UDL for the language should you want to become a user of dBASE Plus, and we have a fairly active and helpful newsgroup at news.dbase.com should you want to join or pick up our UDL files.

          Sorry, that link doesn’t work the way I had hoped it would, and the forums won’t let me edit it, so…just use your newsgroup software using the news.dbase.com link to check out the newsgroup. Clicking this link will take you to the Web News group, which is clumsier than using a newsgroup reader program.

            Your method for changing the tab settings isn’t exactly what the OP is looking for. OP is looking for specifying a tab setting for a single type of file; your solution is changing the setting for all file types unknown to Notepad++'s tab settings box.

              Yes, I know, but short of him doing as Peter says, creating his own lexer/plugin, this will accomplish the same thing for him. If he uses NPP to program in Visual Fox Pro, as it seems he’s suggesting by his request, that he wants to do, then this will accomplish for him. Not many people program outside their normal development environment, where they have their defaults already set, but when they do, they tend to use the same kind of formatting through all the languages, with the exception of maybe Python, that requires specific formatting to function.

              I know in my C programs as well as my dBASE and other programming code files I use a 3 space indentation as I don’t like excessively spaced code when 1 less space per indentation will more likely keep the structure within an 80 character per line limit for printing on letter size if need be and I don’t have to scroll all across the editor to see the code on long runs, so I try to keep everything within that 80 character space and the smaller indents help. I actually had it down to 2 spaces, but then it got harder to tell the structure so I went back up to 3. :)

                Instead of creating your own lexer/plugin (which I don’t think I actually suggested in this discussion, though I have suggested it at other times), the PythonScript plugin allows you to use editor.setTabWidth(tabWidth) to set the tab width… so you could do that in a callback which is activated every time the file is opened or gets focus (there are other examples in the forum, search for BUFFERACTIVATED , and you will probably find an example) – it would check the extension, and if found to be .PRG file, change the tab width.

                  This is the part I thought you were hinting at it needing to be a lexer/plugin from, my mistake…and thanks for the Python reference, too. I’m still not as well versed in that as I’d like either so don’t often think of it. :( Thanks for the additional help. I still like setting the default though, since as I mentioned, that seems to be the way people do it, if they have a preference anyway. Python seems to be the only one that gives me grief about indentation, but…that’s the way IT works, so I don’t get a say in it. :)

                    How exactly does Python present a problem in this area?

                      As Peter mentions that scripting can be used to achieve the desired behavior, I’ll cite this semi-related script that could be used as a basis: https://community.notepad-plus-plus.org/post/54777

                        BTW: I was looking at something else, and found issue#4458 requested the ability to set tab settings for UDL back in 2018, but nothing has been done about it.

                        Using the workarounds presented here are your best choice for the short-to-medium term.

                          In Python, all the code that you type is arranged via correct whitespaces and therefore if at any instance you have a bad indentation, the overall code will not run and the interpreter will simply return an error function.
                          …
                          via: https://www.edureka.co/blog/indentation-error-in-python/

                          Not sure if PythonScript suffers this same issue, but I’ve had at least one interpreter that was adamant since I’ve been trying to figure out Python in the different tutorials. :)

                            I see. It gives YOU grief if YOU can’t keep the indentation consistent. :-)

                                FWIW, here’s a more direct script that handles the desired situation. It uses a dictionary for configuration; for more extension overrides, simply add a line into the dictionary. I call this script TabSettingsOverrideByExtension.py:

                                # -*- coding: utf-8 -*-
                                from __future__ import print_function
                                
                                from Npp import *
                                import os
                                
                                #-------------------------------------------------------------------------------
                                
                                class TSOBE(object):
                                
                                    def __init__(self):
                                        self.config_dict = {
                                            'prg' : { 'use_tab_chars' : False, 'spaces_per_tab' : 3 },
                                            'no_ext' : { 'use_tab_chars' : True, 'spaces_per_tab' : 8 },
                                        }
                                        notepad.callback(self.bufferactivated_callback, [NOTIFICATION.BUFFERACTIVATED])
                                        self.bufferactivated_callback(None)  # fake notification so that the current file gets set up when first run
                                
                                    def bufferactivated_callback(self, args):
                                        complete_pathname = notepad.getCurrentFilename()
                                        filename_with_ext = complete_pathname.rsplit(os.sep, 1)[-1]
                                        if '.' in filename_with_ext:
                                            ext = filename_with_ext.rsplit('.', 1)[-1].lower()
                                            if ext in self.config_dict:
                                                print('setting up for files with extension', ext)
                                                editor.setUseTabs(self.config_dict[ext]['use_tab_chars'])
                                                editor.setTabWidth(self.config_dict[ext]['spaces_per_tab'])
                                        elif notepad.getCurrentLang() == LANGTYPE.TXT:
                                            print('setting up for extensionless files')
                                            editor.setUseTabs(self.config_dict['no_ext']['use_tab_chars'])
                                            editor.setTabWidth(self.config_dict['no_ext']['spaces_per_tab'])
                                
                                #-------------------------------------------------------------------------------
                                
                                # to run via another file, e.g., startup.py:
                                #  import TabSettingsOverrideByExtension
                                #  tsobe = TabSettingsOverrideByExtension.TSOBE()
                                
                                if __name__ == '__main__':
                                    try:
                                        tsobe
                                    except NameError:
                                        tsobe = TSOBE()
                                

                                As indicated in the comments in the code, ideally this script would be run from user startup.py.

                                  For what it’s worth, I couldn’t get this to work, copy pasting the stuff into a new file, stored in the same folder as startup.py and copying and uncommenting the code you pointed had commented importing and the declaration, and the test code keeps erroring our right after the declaration. It doesn’t seem to get down to the main test.

                                    For clarification, here’s the files, in case I screwed something up (like that ever happens) :-)

                                    # 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 *
                                    
                                    console.write("START of machine startup.py\n\n")
                                    
                                    # 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:

                                    And this is the .prg file showing that the changes didn’t take place:

                                      Where it says:

                                      to run via another file, e.g., startup.py:

                                      You need to put the two lines below that, in uncommented form, into startup.py. That’s what “via another file” means. Perhaps this could’ve been made clearer somehow.

                                        That first black box is startup.py code, and the next one down was TSOBE code file.

                                        I did find out that when I changed them around I was bit again by that indentation bug, even in PythonScript, obviously it does it, too. For that error, I just eliminated the spaces and the comment symbol from those two lines…but it still doesn’t work as you suggested…even after I didn’t get any errors…which my startup script no longer stops the console from appearing even though the script closes it.

                                        So until I can not make stupid errors due to possible indentation errors in PythonScript, I’ll just set the default. It’s easier to implement, apparently. Here’s the error I got from the indentation issue.

                                        Traceback (most recent call last):
                                          File "C:\Program Files\Notepad++\plugins\PythonScript\scripts\startup.py", line 43, in <module>

                                        Thanks for the attempt, but I think I’ll wait until I’m more versed in the intricacies of Python before I venture into using it again, or commenting on it’s use. :-(

                                          So, one thing I said originally was:

                                          ideally this script would be run from user startup.py

                                          The operative word there being user.
                                          You edited the machine startup script – not advisable, not really proper – but in and of itself, this isn’t the source of your problems, I don’t think.

                                          But, forget all that “startup” stuff, for just taking it for a test drive…

                                          What I just tried:

                                          • Started up a clean N++ sandbox with PythonScript plugin
                                          • Created a new script giving it the name TabSettingsOverrideByExtension.py
                                          • Copied my “black box” code from above into the file
                                          • Saved the file
                                          • Ran the script from the menus

                                          It runs (quietly) with no output (thus no indentation problems).

                                          If I open a .prg file, it enforces my 3-space tab rule that’s defined in the code.

                                          Thus, I’m not certain where you went wrong. Maybe: It says something about line 43 but the file you show only has 42 lines; not sure what to think about that.

                                          Running the script not-from-startup is fine, it certainly will work that way. But note from the last 5 lines of the file the logic there – you only get to run it one time. Thus if you want to make changes to the script (such as modifying the configuration of additional file types), those won’t be picked up…until you restart Notepad++ and re-run. We don’t want the script to run more than once per Notepad++ session, because it installs a notification handler, and if the script were run multiple times, it would install multiple handlers (not good).

                                            I was bit again by that indentation bug, even in PythonScript, obviously it does it, too.

                                            I’m a bit disturbed by this.
                                            There is no indentation bug, just indentation rules to follow.
                                            And PythonScript is just a plugin version of an embedded Python interpreter, so any files created for use with it must also follow Python’s indentation rules.
                                            I wish I could help further, but I really don’t know how to.
