      Hello, does NPP have a hotkey to hide all comments and empty lines? It could be very useful. For example,

        That feature doesn’t exist natively, as far as I know.

        You can add a feature request, per the instructions in the FAQ – make sure you search the existing issues, to make sure you aren’t duplicating an existing request.

        There might be a workaround, using PythonScript or similar automation tool, but I cannot immediately see how to easily do that. If you’d like a workaround like that, speak up, and maybe someone here will find the time to ponder that.

          Notepad++/Scintilla has a hide/unhide lines feature, but it doesn’t work very well (has inconsistencies). @Claudia-Frank was working on a Pythonscript-based replacement a while ago, but she seems to have departed us for greener pastures. :)

          Still, @PeterJones is on the right track–something could be done to make this a reality. Note that as you’ve defined it, it would only work for full line comments, not partial line comments.

            Hello, @александр-хренников, @peterjones, @alan-kilborn and All,

            I’m thinking of two possible work-arounds :

            First solution :

            You could create a simple Python or Lua script which pastes your code in a new tab, then executes, in the new tab’s text, the regex search/replacement, below :

            SEARCH (?-s)^(\h*[#;].*|\h*)\R

            REPLACE Leave EMPTY

            which just gives your expected text :

            port 1194
            proto udp
            dev tun
            ca ca.crt
            cert server.crt
            key server.key  # This file should be kept secret
            dh dh2048.pem
            server 10.8.0.0 255.255.255.0
            ifconfig-pool-persist ipp.txt
            keepalive 10 120
            cipher AES-256-CBC
            persist-key
            persist-tun
            status openvpn-status.log
            verb 3
            explicit-exit-notify 1
            

            Obviously, no code modification could be done, in the new tab ,only visualization !


            Second solution :

            • Run the regex search/replacement, below, in your real code file :

            SEARCH (?-s)^(\h*[#;].*|\h*)\R

            REPLACE Leave EMPTY

            • In this condensed code, bookmark some parts of your code, that you’re interesting in, for later modifications

            • Performs a Ctrl+Z operation to restore the original contents of your code

            • From beginning of file, press the F2 or Shift + F2 shortcuts to navigate throughout these bookmarks ( which are kept ! ) and modify your code just as you want to ;-))

            Best Regards,

              if you could find a regex which results in a block instead of returning each line then
              we could use something like editor.research and editor.hideLines to make this work.
              What do you think?

                the reason for asking matching a block is because this

                def hideLine(match):
                    line = editor.lineFromPosition(match.span()[0])
                    editor.hideLines(line,line)
                    
                editor.research(r'(?-s)^(\h*[#;].*|\h*)\R', hideLine)
                

                does work but is somehow slow.

                  Hi, @александр-хренников, @peterjones, @alan-kilborn, @eko-palypse and All,

                  Ah, OK, I understand ! I should have found it, directly :-(

                  So, my second attempt would be :

                  SEARCH (?-s)(^\h*(?:[#;].*|)\R)(?1)*

                  REPLACE Leave EMPTY

                  This new formulation decrease, drastically, the number of replacements ;-)) From 301 to 13, in our example !


                  REMARK : Do note the difference between :

                  • (?1) which is a routine call to the referenced group 1 itself ( ^\h*(?:[#;].*|)\R )

                  • \1 which is a back-reference to the present value of group 1

                  For instance :

                  • The regex (\d\d\d)(?1)* would match any range of digits, which is a multiple of 3, where as :

                  • The regex (\d\d\d)\1* would just match any range of 3 digits, possibly repeated

                  Just test these two regexes, against text below :

                  123123123          # 123, repeated 3 times
                  123456789          # digits from 1 to 9
                  123456456          # 123, followed with 456, twice
                  123123123123123    # 123, repeated 5 times
                  12345601234567890  # '123456' + '1234567890' ( 17 digits )
                  

                  As you can see, the regex (\d\d\d)(?1)* is strictly equivalent to the regex (\d\d\d)(\d\d\d)*


                  I’ve, even, found out a shorter regex, for our problem :

                  SEARCH (?-s)^\h*(?:[#;].*|)\R(?0)*

                  REPLACE Leave EMPTY

                  Where the (?0) syntax is a call routine to the entire regex. But, in that case, from my quick explanations, in the remark section, I don’t exactly understand WHY that regex does work too !!

                  Indeed :

                  • The regex (?-s)(^\h*(?:[#;].*|)\R)(?1)* is equivalent to the regex (?-s)(^\h*(?:[#;].*|)\R)(^\h*(?:[#;].*|)\R)* Right !

                  • So the regex (?-s)^\h*(?:[#;].*|)\R(?0)* should be equivalent to the regex (?-s)^\h*(?:[#;].*|)\R(?-s)^\h*(?:[#;].*|)\R(?0)**, which has, again, a (?0)* syntax, leading to a second development, and so on… ??

                  Anyway, it works fine ;-))

                    brilliant, and a script like

                    regex = r'(?-s)(^\h*(?:[#;].*|)\R)(?1)*'
                    
                    def hideLine(match):
                        start, end = match.span()
                        _start = editor.lineFromPosition(start)
                        if _start == 0:
                            _start = 1
                        _end = editor.lineFromPosition(end) - 1
                        editor.hideLines(_start,_end)
                        
                    editor.research(regex, hideLine)
                    

                    could hide the lines.
                    Note, scintilla prevents hiding the first line.

                      Anybody else notice that if you hide lines in this manner, then switch the tab you are editing in N++, then switch back, the lines are no longer hidden??

                        yes, theory - looks like npp is explicitly unfolding code if it can find its own fold marker
                        when activating a buffer. Haven’t checked source code yet. If this is the case, then by
                        either using npps fold marker or buffer activated callback to rehide the lines might solve
                        the issue.

                          There’s a possible solution for this thread’s topic, HERE.
