It seems that when I select all the text (which should exceed that default number), the box stays checked even after I stop selecting.

I’m not quite sure what your meaning is here, but…

…and I presume that when you say “default number”, you mean 1024…

The In selection checkbox isn’t truly dynamic; it isn’t going to change while you are selecting text. It only changes when you invoke search, and here are some examples of that:

input focus in the editing area and you press Ctrl+f input focus in the editing area with Find window also visible, and you use the mouse to activate the Find window

@Freon-Sandoz said in Unexpected match when searching files for an end-quote character (non-ASCII):

I can reproduce the file contents and the unexpected behavior

I was able to do that, too… and now I see what is happening. The character you are calling an end quote is not the Right Double Quotation Mark, U+201D but the Double Prime, U+2033.

Windows-1252 (and Windows-1254) contains the right double quotation mark at 0x94. However, it does not contain the double prime. The entry boxes on the file dialog are always in Unicode. (That’s how it works pretty much everywhere in modern Windows.) But if the file is in ANSI, the file search is done in ANSI, so Notepad++ asks Windows to translate the string you gave it into ANSI. Seeing that there is no double prime character in your current code page, Windows “helpfully” translates it to something that looks a lot like it… the ASCII double quote.

Further confusing the issue is that Notepad++ never loads a file in any code page other than your system code page (which you said is 1252) or Unicode. So when you open the file in Windows-1254, Notepad++ is actually converting it from 1254 to UTF-8 and editing that way. That’s why the search behaved as expected in 1254: it wasn’t really 1254 in, it was in UTF-8.

Bottom line… this behavior actually is “expected”… but not by any normal human being. About the only thing you can do about it is to work in Unicode wherever possible when you are using non-ASCII characters.

It might be possible for Notepad++ to change its search so that it warned you when you tried to search an ANSI document for characters that aren’t possible in that document. I haven’t looked into it in depth; I would guess there must be a call to WideCharToMultiByte somewhere, and it could be passed the WC_NO_BEST_FIT_CHARS flag and the lpUsedDefaultChar output pointer to detect such shenanigans so the program could tell the user about it instead of potentially claiming to find something that isn’t there.

@PeterJones
hello and Thank You…
I think I had read all of the references you posted, and must have misunderstood everything.
(sigh) I’m feeling so old (LoL)
just used your example and it worked perfectly
…
well, except I next will want to enter an exception for cases of a period before the first carriage return.
I think I know how to get that working, now that you’ve given me a great direction.
Again, Thank You!

@rdipardo said in A question about dark mode, plugins, and an owner-draw ComboBox:

Try passing the control’s handle to the ::SetWindowTheme function provided by the uxtheme header, using L"DarkMode_CFD" as the pszSubAppName; to restore light mode, call it with the same arguments, but change pszSubAppName to a null pointer.

Thanks, Robert. At first attempt, this doesn’t appear to solve the problem.

The colors are right with just NPPM_DARKMODESUBCLASSANDTHEME; the problem is that the static control shows unknown text instead of the selected drop-down entry, and attempting to select from the drop-down produces bizarre highlighting and tracking instead of what is expected (and still doesn’t set the static control). Adding the SetWindowTheme call doesn’t change that. Removing NPPM_DARKMODESUBCLASSANDTHEME, of course, makes everything else light, and for the control in question, SetWindowTheme only seems to change the drop-down chevron. Interestingly, NPPM_DARKMODESUBCLASSANDTHEME does get all the colors right, including in the owner-drawn drop-down; it just breaks the functionality in the process.

The problem goes away entirely if I remove the CBS_OWNERDRAWFIXED style (but then, of course, it doesn’t display as intended, showing the color associated with each indicator that can be selected). That’s why I feel like the problem is most likely to do with the sub-classing. I can’t find any clear documentation on how all that works. I don’t even know why the controls are being sub-classed, and not just themed. Maybe there is a way to exempt that control from sub-classing, and do whatever it is that the sub-classing does in my own code?

A pointer to actual documentation on this design, how it works and how it is meant to be used would be wonderful, but I’m guessing no such thing exists. :-(

什么宗教自由？根本纳粹自由。
记不记得40%当时胜选总统的时候多猖狂，大叫在野党「输不起」。

@Murray-Sobol-1 ,

The links you pointed to were to the old 2017 pre-Notepad++-7.6 “Plugin Manager” plugin’s plugin-list. (There used to be a plugin which handled installing/uninstalling plugins in Notepad++. In v7.6, that was integrated into the core Notepad++ code, so that Don could make sure that the Plugins Admin always stayed compatible with Notepad++, rather than relying on a third party for such an important feature.) For nearly a decade, https://github.com/notepad-plus-plus/nppPluginList/ has been the home of the official list of plugins that gets shown in Plugins Admin.

@pierrecoach ,

More on the disappearance of NppCrypt and its repo can be found in this NppPluginList issue. I won’t re-iterate the details, since you can read them there if you are curiuos. But I will say that it looks like @chcg is going to try to resurrect the plugin from archives of the original source code; but it might take him some time. Until then, I’m not sure that any of the links given have any compiled DLL available. Hopefully, you don’t have any critical data that was encrypted on some other machine, that you need to decrypt with the plugin on this new setup. If you do, let us know… (Actually, if you do: do you also have access to the old machine? If so, you can copy the ...\notepad++\plugins\NppCrypt directory from the installation on that machine, and put it on your new machine.)

@PeterJones said in Make notrepad++ default:

It seems a mixed bag: wanting it as system default, associated with lots of file types, and using the Shell Extension, but not wanting to “install” it. It might help us give you better advice if you explain what parts of the “install” that you are opposed to. Is it just storing the settings in %AppData% that you don’t like? Or is there something else? The installer can install into any directory, not just Program Files; the installer can choose to not use %AppData% (as long as it’s not installed in Program Files); the installer automatically registers the Shell Extension for you.

Thanks for all the patience and instruction. I studied those data transfer tutorials, and I “think” I got it right. A little complicated because in Portableapps, in some cases there are up to three iterations of the same file in separate locations. So far, it looks and behaves like the Portableapps.

Is it just storing the settings in %AppData% that you don’t like?

I know the best way to do things is the install. I like to keep things simple. I have very limited space on my OS partition, so I like to keep things as simple as I can by going portable whenever possible, and locating elsewhere. It also makes things easier if you must do an image restore.

That said, considering what you have advised, I think I will do the install. and avoid storing the settings in %AppData%.

After the installation now that I have the working portable version. can I move it to the install directory, mindful of the fact that there will be files in that directory that must retained? Or is it not that simple?

@PeterJones

Thanks for your reply. I will give your solution a try as a Macro learning experience. Maybe I’ll find other uses for it.

But, I just came up with a different solution:

I like Notepad++ so far, so I used the preferences to set Notepad++ as the default for a small number of file types I use occasionally. I renamed the extension of the file I use as my daily journal/log from .txt to my initials .th. I used the file properties to open that file with Windows Notepad.

It’s working well for me. I can use my journal/log with Windows Notepad, and everything else uses Notepad++.

@PeterJones Thank you. I just found this forum after searching about the multiple line issue. I’ve been using Notepad++ for years, fantastic program. First text editor I’d found that did search and replace on end of line charaters since good old Wordstar.

@Mark-Olson You are right, thanx Mark.

thank you

@rdipardo ,
Thanks for pointing out the Native AOT template — I wasn’t aware of it when I started the ARM64 migration.

I did actually try Native AOT early on, but ran into two issues: the export limitations you mentioned, and the resulting DLL size (~57 MB), which felt way too large for a Notepad++ plugin. That’s why I ended up going with DNNE — the plugin DLL stays small (~1 MB), though it comes with the .NET 8 runtime dependency.

How large are the DLLs you’re getting with the Native AOT template? Has trimming improved enough to bring the size down to something reasonable for a plugin?

Hello, All,

Reading that post made me realize that searching for single or duplicate lines is a very common task. Some time ago, for my personal workflow, I had written a method to solve the main cases ! So, in this post, I’m going to show you, from an original file, how to keep :

All single lines, ONLY

All duplicate lines, ONLY

All single lines and the first copy of all duplicate lines

All single lines and the last copy of all duplicate lines

The first copy of all duplicate lines, ONLY

The last copy of all duplicate lines, ONLY

I’ll use a file, named Test_File.txt, that both contains single lines and duplicate lines that appear in 2, 3, 4 or more times. It contains 48 color palettes, found from various sites and added one after another, giving a total of 78,117 records whose 39,532 are single lines and 38,585 are duplicate lines. On the other hand, if we count one copy of all the duplicates, this file contains 11,290 different duplicate lines.

To test my solutions, simply download this UTF-8 file ( 5,937,560 bytes ) from my Google Drive account :

https://drive.google.com/file/d/1aYOpKon4KYw_NXSdj4Tm4Ti_FrygC2ky/view?usp=sharing

Remarks :

Note the definition of single lines : these are lines that differ in characters and/or case from all the other lines of the current file. For example, in this small file of 14 lines, below :

ABC xyz 123 789 HIJ HIJ 123 AbC 123 HIJ abc HIJ 456 xyz

The 5 lines ABC, AbC, abc, 789 and 456 are considered to be single lines, as different in chars and/or case from all the other lines.

The 3 123 lines are considered to be a duplicate line with 3 copies ( Multiple occurrences )

The 2 xyz lines are considered to be a duplicate line with 2 copies ( Multiple occurrences )

Les 4 HIJ lines are considered to be a duplicate line with 4 copies ( Multiple occurrences )

IMPORTANT :

I’ve done some of the work for you, by adding a final column that numbers all lines in this file. Thus, is will be easy to restore the original order of the remaining records, after that each processing is complete. So, in case you need this initial order :

Put the caret right before the present number, at the end of the first line

Run the Edit > Begin/End Select in Column Mode option ( or use the Alt + Shift + B shortcut )

Move to the last line of the file

Put the caret right before the present number, at the end of the last line

Run again the Edit > Begin/End Select in Column Mode option ( or use the Alt + Shift + B shortcut )

=> A ZERO-LINE column mode selection should appear throughout all the lines

Then, run the Edit > Line Operations > Sort Lines Lexicographically Ascending option
=> The original order of the remaining records, AFTER completion of one of the 6 methods below, should be back !

In each procedure, below, 1 or 2 S/R are used. To process them :

First, cancel any existing selection to ensure that any line-end character will be taken in account during the S/R phase

Open the Replace dialog ( Ctrl + H )

Uncheck all box options

Check the Wrap around option

Select the Regular expression search mode

Click on the Replace All button

(1) To keep all the SINGLE lines ONLY ( 39,532 records ) :
Paste the Text_File.txt contents in a new tab

Switch to that new tab and select all text ( Ctrl + A )

Run the Edit > Line Operations > Sort Lines Lexicographically Ascending option

Click anywhere, in the new tab, to cancel the entire selection

SEARCH (?x-is) ^ ( .+ ) .{7} \R (?: \1 .{7} \R )+

REPLACE Leave EMPTY

Perform the IMPORTANT section, above

(2) To keep all the DUPLICATE lines ONLY ( 38,585 records = 78,117 - 39,532 ) :
Paste the Text_File.txt contents in a new tab

Switch to that new tab and select all text ( Ctrl + A )

Run the Edit > Line Operations > Sort Lines Lexicographically Ascending option

Click anywhere, in the new tab, to cancel the entire selection

SEARCH (?x-is) ^ ( .+ ) .{7} \R (?: \1 .{7} \R )+ (*SKIP) (*F) | ^ .+ \R

REPLACE Leave EMPTY

Perform the IMPORTANT section, above

(3) To keep all the SINGLE lines and the FIRST copy of ALL the DUPLICATE lines, found AFTER the sort ( 50,822 records ) :
Paste the Text_File.txt contents in a new tab

Switch to that new tab and select all text ( Ctrl + A )

Run the Edit > Line Operations > Sort Lines Lexicographically Ascending option

Click anywhere, in the new tab, to cancel the entire selection

SEARCH (?x-is) ^ ( ( .+ ) .{7} \R ) (?: \2 .{7} \R )+

REPLACE \1

Perform the IMPORTANT section, above

(4) To keep all the SINGLE lines and the LAST copy of all the DUPLICATE lines, found AFTER the sort ( 50,822 records ) :
Paste the Text_File.txt contents in a new tab

Switch to that new tab and select all text ( Ctrl + A )

Run the Edit > Line Operations > Sort Lines Lexicographically Ascending option

Click anywhere, in the new tab, to cancel the entire selection

SEARCH (?x-is) ^ ( .+ ) .{7} \R (?: \1 .{7} \R )* ( \1 .{7} \R )

REPLACE \2

Perform the IMPORTANT section, above

(5) To keep the FIRST copy of all the DUPLICATE lines ONLY, found AFTER the sort ( 11,290 = 50,822 - 39,532 ) :
Paste the Text_File.txt contents in a new tab

Switch to that new tab and select all text ( Ctrl + A )

Run the Edit > Line Operations > Sort Lines Lexicographically Ascending option

Click anywhere, in the new tab, to cancel the entire selection

SEARCH (?x-is) ^ ( .+ ) .{7} \R (?: \1 .{7} \R )+ (*SKIP) (*F) | ^ .+ \R

REPLACE Leave EMPTY

Then :

SEARCH (?x-is) ^ ( ( .+ ) .{7} \R ) (?: \2 .{7} \R )+

REPLACE \1

Perform the IMPORTANT section, above

(6) To keep the LAST copy of all the DUPLICATE lines ONLY, found AFTER the sort ( 11,290 = 50,822 - 39,532 ) :
Paste the Text_File.txt contents in a new tab

Switch to that new tab and select all text ( Ctrl + A )

Run the Edit > Line Operations > Sort Lines Lexicographically Ascending option

Click anywhere, in the new tab, to cancel the entire selection

SEARCH (?x-is) ^ ( .+ ) .{7} \R (?: \1 .{7} \R )+ (*SKIP) (*F) | ^ .+ \R

REPLACE Leave EMPTY

Then :

SEARCH (?x-is) ^ ( .+ ) .{7} \R (?: \1 .{7} \R )* ( \1 .{7} \R )

REPLACE \2

Perform the IMPORTANT section, above

At the very end of any of these choices, you may delete the extra numeration :

SEARCH (?x-s) .{7} $

REPLACE Leave EMPTY

Then run the Edit > Blank Operations > Trim Trailing Space

Best Regards,

guy038

P.S. :

Note that there is also a native way to get all the single lines and the first copy of all the duplicate lines, found with the present order ( 50,822 records ) :

Paste the Text_File.txt contents in a new tab

Switch to that new tab

Delete the numeration, at end of each line :

SEARCH (?x-s) .{7} $

REPLACE Leave EMPTY

Then, use the Edit > Line Opérations > Remove Duplicate lines option

That’s a pretty solid breakdown 👍

For most cases though, I’d honestly just go with the built-in “Remove Duplicate Lines” unless you specifically need first/last occurrences. Way simpler and less error-prone.

The regex approach is powerful, but yeah… a bit overkill unless you’re dealing with very specific cases or large datasets.

@robstoddard ,

Personally, I just have a file named Peter's Scratchpad.txt that’s always open, where I paste things like that (and, admittedly, things that started like that but have just stayed around in that file for a lot longer than originally intended). And if I save the “temporary data” in the file, who cares? I just delete the stuff out of the file that I don’t need anymore when I don’t need them anymore. That way, I can just Save All or use the Auto-Save plugin as much as I want, without having to ask for a specific feature to “not save this one thing”.

@DougB-MFY ,

Not exactly, but you might get “close enough”

With keyboard+mouse, the shift+scrollwheel would allow you to horizontally scroll without clicking (but having to use the scrollwheel isn’t truly “keyboard”) [END] [space] [backspace] seems to work for me, but it introduces a “fake edit” to get it, so that might annoy you

One of those might be “close enough” for you. But there isn’t a keystroke that does it on its own

@Cletos ,

Depending on what version of Notepad++ you were running, and what’s happened since you last opened Notepad++:

Exit Notepad++ Use Windows Explorer to go %AppData%\Notepad++ You will have session.xml and hopefully a file called session.xml.inCaseOfCorruption.bak . Rename session.xml to session.after.xml Rename session.xml.inCaseOfCorruption.bak to session.xml

Depending on the state, and how little you’ve done since you had the problem, and what version of Notepad++ you are running, that backup session might contain the ~100 txt files.

If not (if there’s no session.xml.inCaseOfCorruption.bak , or if the copy there was written after your session got messed up), there is nothing we can do for you, as the backup session isn’t there. (Hopefully, those 100 txt files were all real files, not new 1 … new 100 with no saved changes ever – if they were, you can look in the backup subdirectory, but again, no guarantees the files are there).

As a reminder to all readers of this Topic, the Community Forum is “The Community of users of the Notepad++ text editor”, as it says in the footer of every single page here (emphasis added). As such, this is just users, talking about Notepad++ and helping each other other. Feature Requests are not tracked here. So all of these “I cannot believe it’s still this way” are effectively just complaining to other users; if that’s theraputic to you, fine; but it won’t tell the developer how many people are interested in that feature being implemented, so it’s just spitting in the wind, so to speak.

We have a FAQ that explains where the Feature Request tracker is. And you could search there (in both open and closed requests) if you want to find the official issue(s) tracking such a request, and see how the developer has responded to such requests, if at all.

@Diederik858 said in I don't want grouped files when I open the download folder in Windows 11.:

When I open the file explorer from Notepad++, I don’t want to have grouped files (day, month, etc.).

When you open the file explorer from Notepad++, you are being directed into a Windows application, the Explorer. And, as such, it follows the Explorer settings for how any individual directory should look. It is exactly identical to you using Windows’ Win+R key and launching explorer "%UserProfile%\Downloads"

As such, you would change the Explorer settings for the Download directory the same way you would from any explorer window (Explorer’s Sort > Group By > (None)) – but this isn’t Notepad++ advice, this is general Windows advice; as such, a Notepad++ forum isn’t the best place for further discovering Windows Explorer features.
