      I think you should hold judgement and wait on the script – I don’t know how saving some reformatting after a paste would disrupt a workflow

      I could be wrong but I took it as sarcasm 😀

        PJ is rarely sarcastic (as a moderator here he is somewhat required to be “even keel”). Usually, the farthest he’ll go is something like this:

        …recent “improvements”…

          I would really want this too
          I posted about it on reddit:
          https://www.reddit.com/r/notepadplusplus/comments/1cp6r8x/apply_autoindent_on_multiline_paste_is_there_away/

          I keep a lot of notes on Notepad++ and I use the Auto-indent feature a lot but it doesn’t work when you paste text.

          for example:

          How to do X?
                                      1) just do the X
                                      2) Blah Blah X 
          

          When I paste something from the clipboard I expect it to look like this:

          How to do X?
                                      1) just do the X
                                      2) Blah Blah X 
                                       Random copied text from internet line 1
                                       Random copied text from internet line 2
                                              Random copied text from internet line 3
                                              Random copied text from internet line 4
          

          but it get pasted like this:

          How to do X?
                                      1) just do the X
                                      2) Blah Blah X 
                                      Random copied text from internet line 1
          Random copied text from internet line 2
                 Random copied text from internet line 3
                 Random copied text from internet line 4
          

          So since I pressed enter and pasted the text, the first pasted line respect the auto-indent, but the subsequent lines does not.

          I think this would be a nice optional feature to add on top of Notepad++ Auto-indent setting, as Follow auto-indent on paste

          ☐ Auto-indent 
                 ☐ follow auto-indent on paste

            Hello, @stoopidoman and All,

            The example provided by @stoopidoman is not clearly explained ! I suppose that what he wants to say is :

            I have this text in a new tab, after hitting the Enter key right after the X char and the trailing space, of the second line :

            How to do X?
                                        1) just do the X
                                        2) Blah Blah X 
                                        
            

            So, the cursor is presently right before the 2) string, but on the third line, after some tabulation or space chars

            Be aware that some plugins may change the default indent behaviour of Notepad++, like, for example, the Elastic Tabstops plugin. In this case, before doing the test, simply disable the plugin !


            Now, I pasted the text , below, from Internet :

            Random copied text from internet line 1
            Random copied text from internet line 2
                   Random copied text from internet line 3
                   Random copied text from internet line 4
            

            When I paste the above text in my new tab, I get the following text :

            How to do X?
                                        1) just do the X
                                        2) Blah Blah X 
                                        Random copied text from internet line 1
            Random copied text from internet line 2
                   Random copied text from internet line 3
                   Random copied text from internet line 4
            

            However, I would have expected this kind of text :

            How to do X?
                                        1) just do the X
                                        2) Blah Blah X 
                                        Random copied text from internet line 1
                                        Random copied text from internet line 2
                                            Random copied text from internet line 3
                                            Random copied text from internet line 4
            

            How to get this last behaviour with pasted text ?

            Best Regards,

            guy038

            IMPORTANT POINT :

            To respect the same displaying as the @stoopidoman’s one, I had to do the following operation, too :

            Edit > Blank Operations > TAB to Space

            Thus, all this story is a bit tricky !


            Certainly, @stoopidoman, previously configured his N++ installation as :

            • Go to Settings > Preferences... > Language > Tab Settings

            • In the list, choose the Normal option

            • Uncheck the Use Default Value option

            • Don’t change the Tab size option

            • Check the Replace by space option

              Sorry all… earlier in this thread I promised a script… and I haven’t delivered.
              It IS more difficult to do a comprehensive solution on this than one would think – and sometimes that can keep one from finishing something to their own satisfaction.
              Let me see what I can do about dumbing it down and at least getting something posted…

                Quite fresh code that uses PythonScript. Got the getClipboardText() idea from a post by @Alan-Kilborn .

                from Npp import editor, notepad
                import re
                
                def main():
                    def getClipboardText():
                        editor = notepad.createScintilla()
                        editor.paste()
                        editor.convertEOLs(eolMode)
                        text = editor.getText()
                        notepad.destroyScintilla(editor)
                        return text
                
                    def repl(m):
                        if useTabs:
                            result = m.group(1).replace(' ' * tabWidth, '\t')
                            size = result.count('\t')
                        else:
                            result = m.group(1).replace('\t', ' ' * tabWidth)
                            size = result.count(' ' * tabWidth)
                
                        if not minSize[0] or size < minSize[0]:
                            minSize[0] = size
                
                        return result
                
                    pos = editor.getCurrentPos()
                    tabWidth = editor.getTabWidth()
                    useTabs = editor.getUseTabs()
                    eolMode = editor.getEOLMode()
                    eol = ['\r\n', '\r', '\n'][eolMode]
                    minSize = [0]
                    text = getClipboardText()
                
                    if not text:
                        return
                
                    parts = re.split(r'\r?\n', text)
                
                    # Normalize indents.
                    re_indents = re.compile(r'^([\t ]+)')
                
                    for index, line in enumerate(parts):
                        modified = re_indents.sub(repl, line)
                        parts[index] = modified
                
                    # Remove indents to flatten.
                    tabLiteral = '\t' if useTabs else ' ' * tabWidth
                
                    while minSize[0]:
                        for index, line in enumerate(parts):
                            parts[index] = line.replace(tabLiteral, '', 1)
                
                        minSize[0] -= 1
                
                    # Add indents to finalize.
                    line = editor.lineFromPosition(pos)
                    indentSize = editor.getLineIndentation(line)
                
                    while indentSize > 0:
                        for index, line in enumerate(parts):
                            if index > 0:
                                parts[index] = tabLiteral + line
                
                        indentSize -= tabWidth
                
                    # Join lines and insert into editor.
                    text = eol.join(parts)
                    editor.insertText(pos, text)
                
                main()
                

                It should get the text from the clipboard, normalize and flatten the indenting, add indents from position from the current editor line and then insert into the editor.

                    @Alan-Kilborn You probably have the os and re modules imported in a previous script as your posted script does not import those modules and can produce NameError tracebacks.

                    Imports:

                    from Npp import *
                    import os, re
                    

                    Added near the top of the script fixes it.

                    The script looks interesting. The comparison between both scripts may suggest some ideas for improvement. ;)

                      Ah, yea, sorry. :-(

                      That’s what I get for “hurrying” to catch up with you in getting something posted (but again, that’s an artifact of me not posting a script much earlier). I’d be surprised if there aren’t further errors in the script I posted. :-)

                      My startup.py does a lot of things, and imports os and re out of necessity there. I usually test scripts I’m going to post with a vanilla setup which would have discovered the error, but this time I didn’t. :-(

                      Yes, for sure!

                      Your script futzes with tab characters vs. space characters; in my script I chose to handle it this way (or, largely not-handle it):

                      • require any common leading whitespace on all lines in the clipboard to be identical for it to be removed
                      • use the leading whitespace on the line where the paste-special is invoked to be used “as is” when prepended to the clipboard lines

                      If users can’t get their tab vs. space indentation consistent (i.e., one way or the other)…I consider this “not my problem”.

                        Its been a while but I finally got some time to look and this again.

                        Now that I saw the comment in the code pointing to PythonScript and setting up a HotKey it ended up being quite easy.

                        Your script seems to do the right thing for what I need and if it doesn’t I’ll learn enough Python to update it and update this post.
