    It may be worth pointing out that if you always want to hard-wrap lines at a the same column, that THIS THREAD treats the topic fairly exhaustively, and requires no external scripting.

      @Ekopalypse said in PythonScript to replace TextFX Rewrap function?:

      There is a fill method that does the “joining” - let’s see if that needs to be called in advance.

      It might not have been the way you thought of, but I used an re.sub() in the rewrap function which first merges the equivalent of \h*\R into a single space. With that, and using the replace_whitespace=True, the behavior of the script seems to match the essential nature of the Rewrap command from TextFX:

        @Ekopalypse My use case is between the two. I have texts that consist of long and short lines, sometimes with excessive white space, that I want to normalize to 78 character text.

          eol = {0:‘\r\n’, 1:‘\r’, 2:‘\n’}[editor.getEOLMode()]

          editor.endUndoAction()

          main()

          I tried that code but it does not keep the paragraphs separated. In TextFX, the rewrap did only join if there was no blank line between two lines. One or more blank lines where treated as a paragraph break and converted to one blank line to keep the paragraphs intact. Can the code be changed to do that?

            I will try to understand what the TextFX code does and port to Python accordingly. I will post an updated code later today or tomorrow at the latest.

              I think this accomplishes your goal:

              The input text selection

              these are two really long paragraphs that have lots and lots and lots
              and lots and lots and lots and lots and lots of words
              
              this is the second of the really long paragraphs that have lots and lots
              and lots and lots and lots and lots and lots and lots of words
              

              when run with a value of 16 will end up like:

              these are two
              really long
              paragraphs that
              have lots and
              lots and lots
              and lots and
              lots and lots
              and lots and
              lots of words
              
              this is the
              second of the
              really long
              paragraphs that
              have lots and
              lots and lots
              and lots and
              lots and lots
              and lots and
              lots of words
              

              and that output, when selected and run again with 72, will end up back as the original.

                @PeterJones the second version of the code does not work if I mark a whole text. If I mark only one paraghraph, then it does work but only for english texts. As soon as I run it against a German text with Umlauts (ä,ö,ü, etc.) (UTF-8 or UTF-8-BOM) it converts the Umlauts to strange characters and paragraph breaks.

                I tried it with this example:

                Um die sechste Morgenstunde des 3. Juli dieses 
                Jahres war ich gerade, nichts Böses ahnend, dabei, meine Petunien zu begießen, als ich einen großen, bartlosen, blonden jungen Mann bei mir eintreten sah, geschmückt mit einer goldenen Brille, das Haupt bedeckt mit einer 
                deutschen Schirmmütze. Trübselig, wie ein Segel längs des Mastes, wenn der Wind sich gelegt hat, baumelte ein weiter Überzieher aus einem sehr dauerhaften englischen Stoff um seine Person. Handschuhe trug er nicht; seine rohledernen Schuhe hatten derartig mächtige, breite Sohlen, daß deren Rand den Fuß mit einer Art Trottoir umgab. In einer 
                Seitentasche, ungefähr über dem Herzen, machte sich, unter dem glänzenden Stoff vage ihre Form abzeichnend, eine große Porzellanpfeife bemerkbar. Nicht einmal im Traume wäre ich darauf verfallen, den Unbekannten zu fragen, ob 
                er an einer der deutschen Universitäten studiert habe. Ich setzte meine Gießkanne hin und begrüßte ihn sofort auf deutsch mit einem schönen »Guten Morgen!«.
                
                »Mein Herr«, erwiderte er französisch, 
                wenn auch mit einem erbärmlichen Akzent, 
                »ich heiße Hermann Schultz; ich habe gerade 
                einige Monate in Griechenland verbracht, wo 
                übrigens Ihr Buch mein ständiger Reisebegleiter war.«

                  @Reiner-Bühl

                  an updated version, tested with utf8 and ansi

                  def rewrap(text, pos, eol):
                      paragraphed = re.sub(eol+eol, '\0xB6', text)

                      unparagraphed = re.sub('\0xB6', eol+eol, joined)
                      retlist = []
                      for linetext in unparagraphed.splitlines():
                          if linetext == '':
                              retlist.append('')
                  
                          for partial in wrap(linetext, pos, expand_tabs=False, replace_whitespace=False, break_on_hyphens=False):
                              retlist.append(partial.lstrip())
                  
                  
                      return retlist
                  
                  def main():
                      _prompt = "Wrap at position:"
                      _title = 'ReWrap'
                      default_pos = 78
                      if editor.getSelectionEmpty():
                          _prompt = "ATTENTION!! - Since nothing is selected, the WHOLE document is rewrapped.\n" + _prompt
                          _title = "ATTENTION!! - " + _title
                      pos = notepad.prompt(_prompt, _title, default_pos)
                      if pos is None:
                          return  # cancelled
                      else:
                          pos = int(pos)
                  
                      start, end = editor.getUserLineSelection()
                      start_pos = editor.positionFromLine(start)
                      end_pos = editor.getLineEndPosition(end)
                  
                      eol = {0:'\r\n', 1:'\r', 2:'\n'}[editor.getEOLMode()]
                      rewrapped = rewrap(editor.getRangePointer(start_pos, end_pos-start_pos), pos, eol)
                      editor.setTarget(start_pos, end_pos)
                      editor.beginUndoAction()
                      editor.replaceTarget(eol.join(rewrapped))
                      editor.endUndoAction()
                  
                  main()
                  

                  The use of the Unicode B6 seemed to confuse the python2 re engine, and furthermore python re does not know \h, \s had to be used instead.
