      Could it be that you have two views open, one with a perl document and one with a normal text document?

        I have many documents opened in different Windows ([edited]TABS). Is this what you mean by “views” ?

        No double Windows at a time like in “compare” or so.

          Ok, then it seems we have learned that the id is not always the same.
          Gimme a second to see what needs to be changed to use editor.getLexerLanguage() instead.

            all right, take your time.
            i’ll be there late tonight.

            about DWservice, it’s GNU, hosted in DE I guess, not smthg like Teamviewer. But perhaps you are right, one should always be paranoiac.

              I’m living in DE but have to admit, that I haven’t heard of DWservice before, shame on me :-)

              Changes
              line 9 to BUILTIN_LEXER = 'perl'
              line 111 self.lexer_name = BUILTIN_LEXER.lower()
              line 219 to self.doc_is_of_interest = True if editor.getLexerLanguage().lower() == self.lexer_name else False

              As python is very picky about whitespaces make sure that you either use
              spaces or tabs for indentation only. Best python practice is to set
              Settings->Preferences->Language->TabSettings->Python
              Tab size = 4 and check replace by space checkbox
              (if this isn’t your default setting, of course)

                Line numbers don’t match because I already commented out some of your lines but kept them in the file, and duplicated them with my own changes. But I did do the changes at the places you told me to do them.

                  check line 111 - it defines the lexer_name

                    OOPS, yours :== self.lexer_name, mine :== self_lexer_name, I am really a dumb when dealing with OO programming, can’t realize that ‘self’ is the current object and of course separated by a dot.

                    Colour has changed for q* keywords and there text (black on dark blue, can’t read but now just need to ajust the colors).
                    No change for here docs, but don’t know if I properly set the colors, have to check.

                    Send you a screen copy in a few minutes.

                      All right, nearly done: with the following regexp in your python code:

                      regexes[(1, (255,0,128))] = (r'\bq[rwqx]{0,1}\b([^\h]).*?\1|(\bq[rwqx]{0,1}\b\h+(\w).*?\3)', [0])
                      regexes[(2, (255,0,128))] = (r'\bq[rwqx]{0,1}\b\h*(\(.+?\)|\[.+?\]|\{.+?\})', [0])
                      regexes[(3, (0,0,0))] = (r'(?s)((<<)"*(\w+?)"*;.*?\3)', [2])
                      regexes[(4, (0,0,0))] = (r'(?s)((<<)\h+"(\w+?)";.*?\3)', [2,3])
                      

                      I get the following colors:

                      q* colors OK, here docs no

                      Q* colors are good {well I might have an uggly taste in colors but at least they match ;-)) }

                      Would you have any clue about why the here docs= are still not handled properly ? They should be black, I think.

                        the regexes assumes double quotes and semicolon directly attached to EOT.
                        Like

                        print << "EOT";
                        
                        --------------------- separation line ------------------
                        
                        EOT
                        

                        Is there a rule how this is specified?

                          I think I found why.
                          Your regexp says :
                          r'(?s)((<<)"*(\w+?)"*;.*?\3)'
                          would not it be better if :
                          r'(?s)(\h*(<<)\h*"*(\w+?)"*\h*;.*?\3)'

                          ???

                          To answer your question:

                          Perl allows

                          1. <<TEXT,
                          2. << TEXT
                          3. <<‘TEXT’ / << ‘TEXT’
                          4. <<“TEXT” / << “TEXT”

                          meanings differ in each case…

                            To be honest - I’m not a regex expert at all :-D
                            If you, as a perl developer, say so I would absolutely believe it is :-)

                              In your Python regexp, what’s the meaning of:

                              1. “\3”
                              2. “, [2]” and “[2,3]” ?

                              If I can understand what I think I could translate a Perl regex code into python (for this case at least).

                                What about using this
                                (?s)((<<)\h+(["|'])(\w+?)\3\h*;.*?\4)

                                  1. is the boost:regex convention to denote match group 3
                                    and
                                  2. defines which match group actually should be painted

                                  Like if you have:

                                  r'(word1)(word2)(word3)', [2,3]
                                  

                                  would mean that only word2 and word3 would be painted
                                  whereas if you would specify

                                  r'(word1)(word2)(word3)', [0]
                                  

                                  everything would be colored.

                                  Does this makes sense to you?

                                    I don’t understand your regexp syntax. Perhaps too ‘pythonized’ for me.

                                    (?s) : what does it mean ? is it ‘s///’ ? or really a non capturing group of ‘s’ ???
                                    \3 \4 : are they $3 $4, I don’t think as I can’t see a 4th accumulator

                                      (?s) is a modifier telling the engine that the dot matches line endings
                                      and yes, the engine uses \1 and $1

                                      Here the link to the documentation - maybe easier for you.

                                            Ok
                                            another one: in Python you must say ["|'] instead of Perl ["'] (‘either one of the set’) ? Is that what it means ?
