      Don’t bother too much w/ my pb, concentrate on your job

      :-) That’s for sure - we are allowed to surf the web as long as work related stuff is
      priority 1 and we take this very seriously.

      bit confused.

      Actually me too.
      If you don’t mind - would you try to do the following.

      1. Restart npp (Only one single instance should run)
      2. Click Plugins->PythonScript->Show Console
      3. Click Plugins->PythonScript->Scripts->NAME_OF_YOUR_SCRIPT
        -> check if there is an error reported in the console, if so - stop here and post it
        If no error has been written to console
      4. Open a perl file or a new file and change the language to PERL and put some code in it
        -> check if there is an error reported in the console, if so - stop here and post it
        If no error has been written to console
        execute the following in the console run edit box
      editor.getLexer()
      

      Does it return 6 as specified in the script (BUILTIN_LEXER_ID = 6)?
      If it does, execute the following in the console run edit box

      EnhanceBuiltinLexer
      

      What does it return?

        1. restarted NPP, only one instance: checked

        2. python console:

          Python 2.7.15 (v2.7.15:ca079a3ea3, Apr 30 2018, 16:30:26) [MSC v.1500 64 bit (AMD64)]
          Initialisation took 109ms
          Ready.

        3. Plugins/PythonScript/Scripts->EnhancePerlLexer.py: checked. Result: NOTHING in the console, no error but no confirmation that the py script as run either, is it normal?

        4. Opened a new window, made it Perl syntaxing. See screen copy for colors. Did not do it. Here is the code for the colors in your script that I modified:

          regexes[(1, 5)] = (r’\bq[rwqx]{0,1}\b([^\h]).?\1|(\bq[rwqx]{0,1}\b\h+(\w).?\3)', [0])

          regexes[(2, 5)] = (r’\bq[rwqx]{0,1}\b\h*((.+?)|[.+?]|{.+?})', [0])

          own defined color and non-default match group(s) used

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

        Executed editor.getLexer(), got a return of 1; executed EnhanceBuiltinLexer, results:

        Python 2.7.15 (v2.7.15:ca079a3ea3, Apr 30 2018, 16:30:26) [MSC v.1500 64 bit (AMD64)]
        Initialisation took 125ms
        Ready.
        >>> editor.getLexer()
        1
        >>> EnhanceBuiltinLexer
        <class '__main__.EnhanceBuiltinLexer'>
        

        Seems that I get the wrong return code… don’t I ?

          Indeed - would you mind executing the following in the console run edit box?

          editor.getLexerLanguage()
          

          no error but no confirmation that the py script as run either, is it normal?

          yes.

            I get 1 returned if the language is set to Normal Text.
            Sorry for asking, but sure you have set the language to Perl?

              >>> editor.getLexerLanguage()
              'perl'
              

              Would it be (more) convenient for you to connect directly on my machine ? (DWservice) ?

                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?
