  kopalypse, @peterjones, @alan-kilborn and All, Ah… interesting problem ! So, Andre, you tried these 7 regexes expressions, listed below, without finding a way to only match from the last <td class="fiddlesticks_ string till the very end of file :-( (A1) (?!<tr trow="\d">)<td class="fiddlesticks_[A-Za-z0-9-]+"><span>.+?</span></td></tr>\z (A2) <td class="fiddlesticks_[A-Za-z0-9-]+">(?!<tr trow="\d">)<span>.+?</span></td></tr>\z (A3) <td class="fiddlesticks_[A-Za-z0-9-]+"><span>(?!<tr trow="\d">).+?</span></td></tr>\z (A4) <td class="fiddlesticks_[A-Za-z0-9-]+"><span>(?!<td class="fiddlesticks_).+?</span></td></tr>\z (A5) <td class="fiddlesticks_[A-Za-z0-9-]+"><span>(?!here is some text).+?</span></td></tr>\z (A6) <td class="fiddlesticks_[A-Za-z0-9-]+"><span>(?!another string).+?</span></td></tr>\z (A7) <td class="fiddlesticks_[A-Za-z0-9-]+">(?!miscellaneous data)<span>.+?</span></td></tr>\z Indeed : Regex A5 matches anything from <td class="fiddlesticks_de2f"> till the very end of file All the other regexes match from <td class="fiddlesticks_a1bc"> till the very end of file Before providing some solutions to your problem, I’m going to explain, first, what all these regexes match and why ! First note that all your regexes end with </span></td></tr>\z. So, whatever is matched so far, it must go on matching… till the string </span></td></tr> at the very end of file Regarding the regex A1 : It first looks for a string <td class="fiddlesticks_[A-Za-z0-9-]+"> and, of course, when caret is right before the string <td class="fiddlesticks_a1bc">, the negative look-ahead (?!<tr trow="\d">) is necessarily true. So, it matches, so far, the <td class="fiddlesticks_a1bc"> Now, the regex engine tries to process the remaining part <span>.+?</span></td></tr>\z. You could say : as there is a lazy quantifier, it will match from <span> to its corresponding </span>. Not at all ! All of us, we must remember that the fundamental characteristic of regex engines is that they try, BY ALL MEANS, to match something. So, when you get a message Find: Can't find text "something" you’re absolutely sure that all possibilities and alternatives, if any, have been tried and that the overall regex cannot find a solution ! As, the overall regex must be anchored to the very end of file, the regex <span>.+?</span></td></tr>\z match the first <span>. Then .+? matches the shortest range of text till … the last </span></td></tr> at the very end of file ! Regarding the regex A2 : The first part <td class="fiddlesticks_[A-Za-z0-9-]+"> matches the <td class="fiddlesticks_a1bc"> string Then, the part (?!<tr trow="\d">)<span> match <span> which is obviously different from any <tr trow="#"> string And the remaining part .+?</span></td></tr>\z matches, as above the shortest range of text till the last </span></td></tr> at the very end of file Regarding the regex A3 : it almost identical to the regex A2, except for the fact that, right after the first <span> string, there’s no <tr trow="#"> string, too ! Regarding the regex A4 : it’s a variant of the **regex A3 as, right after the first <span> string, there’s no string <td class="fiddlesticks_ at all ! So, again the remaining part .+?</span></td></tr>\z matches all text after the first <span> till the very end of file Regarding the regex A6 ( I’ll speak of regex A5 later ) : Again, the part <td class="fiddlesticks_[A-Za-z0-9-]+"><span> matches the string <td class="fiddlesticks_a1bc"><span> The negative look-ahead (?!another string) is necessarily true when carat is after the first <span> string And the final part .+?</span></td></tr>\z matches, as said above, the shortest range of characters till it reaches the very end of file ! Regarding the regex A7 : First, the regex <td class="fiddlesticks_[A-Za-z0-9-]+"> matches the string <td class="fiddlesticks_a1bc"> Then, the part (?!miscellaneous data)<span> matches <span>, which is, of course, different from the miscellaneous data string Finally, the part .+?</span></td></tr>\z matches the shortest range of characters … till it reaches the very end of file ! Regarding the regex A5 : The regex <td class="fiddlesticks_[A-Za-z0-9-]+"><span> matches the string <td class="fiddlesticks_a1bc"><span>, first Then, the negative look-ahead (?!here is some text) is evaluated. As this text does follow the <span> string, the look-ahead is false So, the regex engine go on, finding the string <td class="fiddlesticks_de2f"><span> which is matched by the part <td class="fiddlesticks_[A-Za-z0-9-]+"><span> Again, the negative look-ahead (?!here is some text) is tested. As the present text is another string, which is different from the here is some text string, the negative look-ahead is true So, the final part .+?</span></td></tr>\z matches all the remaining of the text, till the very end of file Now, here are a solution, using your different look-aheads syntaxes (?!here is some text), (?!another string), and (?!miscellaneous data) Let’s consider the four regexes below : (G1) (?-i)<td class="fiddlesticks_[A-Za-z0-9-]+"><span>.+?</span></td></tr>\z (G2) (?-i)<td class="fiddlesticks_[A-Za-z0-9-]+"><span>(?!here is some text).+?</span></td></tr>\z (G3) (?-i)<td class="fiddlesticks_[A-Za-z0-9-]+"><span>(?!here is some text)(?!another string).+?</span></td></tr>\z (G4) (?-i)<td class="fiddlesticks_[A-Za-z0-9-]+"><span>(?!here is some text)(?!another string)(?!miscellaneous data).+?</span></td></tr>\z These 4 regexes will catch the text from the first, second, third and fourth <td class="fiddlesticks_ string till the very end of file ! For instance, in regex G3, in order to match the string <td class="fiddlesticks_g-hi"><span>miscellaneous data</span> we need that, after the <span> string, the expression is different from here is some text AND different from the another string text ! Note that when multiple consecutive lookheads are evaluated, the working position of the regex engine does not change : it’s the location right after any <span> string As you can see, if you always want to get the last range, near the end of file, it would be difficult to generalize as you would be forced to add as many negative look-aheads than the number of strings to avoid to :-(( So, the correct solution is to find : First, a string <td class="fiddlesticks_••••"><span> Then, any range of text which does not contain, for instance, the string <td at any location of that range, till the very end of file These conditions can be achieved by the regex (G5) : (?-si)<td class="fiddlesticks_[A-Za-z0-9-]+"><span>((?!<td).)+\z Note the leading modifiers (?-si) which forces : The . meta-character to match standard characters only ( not EOL ones ) The search to be processed in an non-sensitive to case way As you can see, the part ((?!<td).)+ matches any standard character, if, at each position, the string <td cannot be found, between a <span> string and the very end of file ! However, note that the regex G6 : (?-i)<td class="fiddlesticks_[A-Za-z0-9-]+"><span>(?!<td).+\z would just match like most of your regexes ! Indeed, in that case, the negative look-ahead is tested right after a <span> string, only Best Regards guy038

  @PeterJones said in HTML colors in proper colors: he only uses indicator#0 because the class uses SC_INDICFLAG_VALUEFORE. So you might be able to get away with all the colors working. Well, I was thinking that the OP would want to have many possible of these #xxxxxxx on screen at once, all representing their color. An indicator must be dedicated and can only have one color at a time, for all occurrences of that indicator on screen. So this doesn’t seem all that viable if that is what truly is wanted/needed. per the current Scintilla Docs, there are only 35 indicators available But from the 35 some are already used by Notepad++ for other things, so the number is really much smaller. Well, I guess if you don’t use those other things…but I’m not sure at what point Notepad++ configures them, so even if you grab the used ones for your purposes, you might find them overwritten at certain points, with Notepad++ stock color styles.

  @Cyrille-Piatecki-0 , I’m not 100% sure I understand what you mean. It seems to me that you have multiple similar source files, which you want to edit one-at-a-time in Notepad++ while viewing one in your web browser. And that you want to automatically close the one you are currently editing when you start to open a new one. Personally, I would have all the copies open in multiple tabs in Notepad++, and then just switch the active tab. There is an old, no-longer-documented way to get Notepad++ to look more like Windows Notepad: if you exit Notepad++, go into the Notepad++ executable directory and create an empty file called asNotepad.xml, and re-run Notepad++, it will run in a way that no longer shows tabs, and when you open a new file, it is the only file visible. However, if you go to the Windows menu, you will find that the other files are still open, and switch to them there. So it doesn’t technically close the file before opening the new one, but it sure looks like it. (If you want to later get out of that mode, you have to delete that XML file and restart Notepad++.) If that’s not sufficient, there is the macro tool. Unfortunately, the File Open isn’t recordable, though it can be in a manually edited macro. First, setup the new macro: Close all instances of Notepad++. Edit %AppData%\notepad++\shortcuts.xml Add this inside your <macros> section: <Macro name="Close All Then Open" Ctrl="no" Alt="no" Shift="no" Key="0"> <Action type="2" message="0" wParam="41004" lParam="0" sParam="" /><!-- this will close all active files --> <Action type="2" message="0" wParam="41002" lParam="0" sParam="" /><!-- this will launch the File | Open dialog --> </Macro> Save Exit Notepad++ When you run Notepad++ again, Macros > Close All Then Open will exist, and will run those two commands. Using Macro > Modify Shortcut / Delete Command, select Close All Then Open, and assign a keyboard shortcut to your liking, and you now have a keyboard shortcut that does what (I think) you want. If this isn’t what you want, you will need to explain yourself better. Good luck.

  It’s nearly impossible because the current tabbar is based on SysTabContorl32, and we cannot modify the source code of SysTabContorl32. The only solution is to replace it with something you have full control of. Luckily, you don’t have to start from scratch. the WINE ( is not a emulator ) project has mimicked the behaviour of SysTabContorl32, and all efforts are contained in a single source file, tab.c. So theoretically we can build the chrome-like “tabs grouping” feature basing on WINE’s tab.c, but still, it requires a lot of coding works to achieve success.

  Thanks for the heads up on the Edit Popup ContextMenu! My issue was the reverse of the OP’s in that the “Search on Internet” item was in the “On Selection” but not in the popup menu. The cause being the missing menu item in an older config file not over-written due to an other (resolved) issue.

  Hi, @a-former-user, Yes !! That all concerns Notepad++, only ! So, as I said before : Open Notepad++ Copy the text, below, in a new N++ tab ( Ctrl + N ) Leicester Dog and Duck Pub aaaaa 11111 Beefy Cow Steakhouse bbbbb 22222 Snail and Lettuce Pub ccccc 33333 Dukes Head Hotel ddddd 44444 If the last line 44444 does not end with a line-break, hit the Enter key to add one ! Open the Replace dialog ( Ctrl + H ) SEARCH (?-s)\A([^\t\r\n]+)\R(?s)(.+\R)(?!\t)$|(?-s)(.+)\R(.+)\R(.+)\R(.+)(?=(?s:.+\t(.+)\t\z))|^\t.+ REPLACE (?1\2\t\1\t)(?3\7\t\3\t\4\t\5\t\6) Tick the Wrap around option Select the Regular expression search mode Click TWICE on the Replace All button ( Note that, in addition, any subsequent click on the Replace All button does nothing ! ) You will obtain this output : ~~~diff Leicester Dog and Duck Pub aaaaa 11111 Leicester Beefy Cow Steakhouse bbbbb 22222 Leicester Snail and Lettuce Pub ccccc 33333 Leicester Dukes Head Hotel ddddd 44444 Copy these 4 lines in the clipboard ( Ctrl + C ) Open Excel Open a new empty sheet Paste the clipboard’s contents ( Ctrl + V ) in cell A1 You should get a table of 4 rows × 5 columns, with the word Leicester in the first column of any row ;-)) Best Regards guy038

  Thank you @PeterJones for your quick reply and for confirming that it’s a Windows “feature”! I thought that I missed to change something in my Notepad++ configuration, that’s why I asked. As this is my “work” laptop (and the JumpList is working fine for np++ for “normal” files) I don’t want to install too many tools - only those I can justify that I need them for my work. ;) E.g. the plugins for xml and json - they are great! Thanks again!

  @Tak-Li That is currently (where currently = up to and including 7.9.5) not possible. The workaround is to let it go “too far” and then press Ctrl+z and then Ctrl+Shift+z. This will “undo” the most recent replacement (the one you wanted to stop at) and then “redo” the replacement (and leave the caret at the location of the replacement).

  @Jose-Emilio-Osorio How to insert Carriage Return “CR” before “LF” at the end of each line ? They are probably already there and you need to do exactly nothing to insert them. If you are “unconfident” that Notepad++ is doing this for you, press the “Pilcrow” toolbar button…the one with this symbol on it: In the Notepad++ toolbar, it is blue in color, not black. With that toolbar button in the depressed state, you will see the CR and LF in a Windows file, example:
