@xomx @PeterJones
Thank you for your assistance. I am currently using 2 monitors, both are the same model, I believe capable of 2560x1440. My second monitor is set in portrait mode. On the 2nd monitor most of the after image/moving seems to remain on screen when the after image moves higher than the first screen. (I am assuming about 1440 pixels from the bottom of the screen)

Prior to updating to 24h2, I had an update of 23h2 about a week ago, and did not notice any unusual behavior with the undocked search results. I honestly don’t remember if before the 24h2 update, if when I attempted to drag the undocked search results if the window moved or if I just had an outline that would show me when the window would be.

For clarification, the Search Result window is not missing. And prior to messaging here, I had deleted my config files. As well as removing and installing the latest version of Notepad++.

Please let me know if any more information would be of assistance.

So it really was a Scintilla v5.5.6 bug, fix for its next version:

@Alan-Kilborn
thankyou for the advice

@Denine ,

The owner is working on it, but, per here, it’s not as simple as one might hope.

@zitot-hawaii-edu said:

in distraction free mode, the two views/panes became only one view/pane…but I need both

Hmm, presumably, the designer of distraction free mode decided that a second pane would be distracting… :-)

@kracovwolf ,

[?i-s].*?music.*

The [?i-s] is a character class matching the question mark or lowercase i through s. I think you meant (?i-s) to change mode to match case-insensitive with . not matching newline.

@PeterJones

4 years later, and option 1 just saved me some grief.

I had 2 sessions open and autoindent started misbehaving, so I closed the window in which I had about 40 files open, and realized it, just too late. Re-opening one of the files, of course, opened it in the other session, where I had 1 file open. Luckily, the session.xml file had the large session, so all is good.

It’s not that my files were unsaved, it’s just that the session was set up in a convenient way for the work that I was doing.

Cheers for a helpful solution!

Thanks @PeterJones, I really appreciate your time! I spent a chunk of time yesterday too trying to work out the regex if-then-else functionality before I gave up.

I wouldn’t want to pick up everything that starts with \ because that will pull in a lot of commands that aren’t related to document structure (every command starts with \). For example, here’s my minimum working example with a numbered list in it, and that picks up the \begin{enumerate} and \items:

\documentclass{scrreprt} \begin{document} \chapter{Chapter 1 with sections} \section{1.1} \subsection{1.1.1} Lorem \subsection{1.1.2} ipsum \section{1.2} \begin{enumerate} \item dolor \item sit \item amet \end{enumerate} \chapter{Chapter 2 with no sections} consectetur adipiscing elit. \chapter{Chapter 3 with unnumbered sections} \section*{Heading with no number} Phasellus mollis posuere ante vel tincidunt. \section*{Second heading with no number} Donec faucibus tellus sapien, vitae fringilla nulla bibendum eget. \appendix \chapter{Appendix A} \include{document} \chapter{Appendix B with sections} \section{B.1} Nam mauris nisl, cursus at erat in, \section{B.2} molestie luctus nulla. \end{document}

… but picking up the \chapter{} as a function along with the \section{}s is a great workaround!

Here’s what I have now:

<?xml version="1.0" encoding="UTF-8" ?> <!-- ==========================================================================\ | To learn how to make your own language parser, please check the following | link: https://npp-user-manual.org/docs/function-list/ \=========================================================================== --> <NotepadPlus> <functionList> <parser displayName="LaTeX Syntax" id ="latex_class" commentExpr="(?x) (%.*?$) # Comment " > <function mainExpr="(?x) # free-spacing (see `RegEx - Pattern Modifiers`) (?im-s) # ignore case, ^ and $ match start/end of line, dot doesn't match newline \\begin{document} # match start of document " > </function> <classRange mainExpr ="(?x) # free-spacing (see `RegEx - Pattern Modifiers`) (?m) # ^ and $ match at line-breaks (?'CLASS_START' ^\s* # optional leading white space before \chapter \\(chapter\*?) ) (?s:.*?) # whatever, (?= # ...up till \s* # ...optional leading white-space of (?: (?&amp;CLASS_START) # ...next header | (\\end{document}) # ...or end of document ) ) " > <className> <nameExpr expr="(?x) # free-spacing (see `RegEx - Pattern Modifiers`) (?<={) # brace before name .*? # name (?=}) # brace after name " /> </className> <function mainExpr="(?xm-s) # free-spacing (see `RegEx - Pattern Modifiers`) \\(chapter| # match chapter so that even \chapters with no \section appear section| # match \section subsection| # match \subsection )\*?{.*} # match starred and unstarred commands " > <functionName> <funcNameExpr expr=".*"/> </functionName> </function> </classRange> </parser> </functionList> </NotepadPlus>

And the result on the sample file:
Screenshot 2025-05-14 094212.png

I modified the classRange mainExpr because I wanted to also match indented \chapter{}s (like I have for the appendices in the new sample file). After that change I found that the last \chapter{} wasn’t being matched with \Z so I changed the alternate search to look for \end{document} instead (which will always appear) and that worked.

Thanks for your help!

@Malek-A ,

If your active font has a glyph for that character, then whether it looks like an emoji or not depends on that font. If your chosen font does not contain the glyph, depending on your Notepad++ DirectWrite preferences, Windows OS may go through some alternate fonts to find one that has the glyph.

For example, for Yin Yang, if I use my default Fira Code font, which does not apparently have the glyph for that symbol, it uses an emoji-style rendering, because whatever backup font Windows OS has chosen uses the emoji rendering:
7ac95ec0-141b-4916-8dbd-7d0fab933f02-image.png

If I switch to DejaVu Sans Mono, which does have a glyph for that font, it looks like a normal character:
73f467c9-8ca2-4f1d-b6e3-1c26be584638-image.png

(both those screenshots were zoomed, so that you could actually make out the character rendering)

It’s not actually a Notepad++ specific issue: I can see similar even in my browser: ☯/☯ renders as

3414e66a-bbd0-446e-be30-b97906eca8ea-image.png

for me – once again, because of the font choices in the browser settings, and whether or not those fonts have a glyph for the given character.

Windows uses what it calls the CompositeFont for doing glyph substitutions. If you change your Notepad++ Settings > Preferences > MISC > …DirectWrite… / Rendering Mode , you can influence whether or not the substitutions happen (turning it off in older versions, or to GDI (most compatible) in newer versions should stop the substitution, but might mean that all unrecognized characters show up as �.

You can read more about CompositeFont in some of my old posts, or searching the web in your favorite engine.

“Some characters are not displayed [Unicode]” [May 2018] “Default font for Devanagiri script” [Apr 2019] “门这个字显示有问题” [Oct 2024] search here for other mentions of CompositeFont [insert link to favorite search engine’s results here]

The web search is mostly likely to be helpful in figuring out how to edit your Windows OS settings to make use of a different backup/alternate font for a given range of characters, if you end up going down that route.

But the best advice is to pick a font that has a glyph that you like for every unicode character you care about. (Easier said than done, I know)

@Palittle-Studios,

Not A Bad Idea But With Like Step-By-Step Tutorials, It Will Be GOOD.
You Could Mention Libraries Too

The FAQ is sufficient for anyone who already knows how to compile their code; once they know that, they can just put those compilation commands into the examples given. That’s as “step-by-step” as anyone who knows how to code needs. Libraries are done inside Notepad++ the same way they are when typing C/C++ code in any text editor; and passing libraries to the linker is done in Notepad++ the same way it is with any command-line compiling. All Notepad++ (and the Run menu or NppExec plugin or whatever you choose from the FAQ) are doing is helping you to “memorize” those command line calls, so that you don’t have to type them completely every time you compile.

If you need help learning C/C++, or learning how to compile and link C/C++ from the command line, there are about a gazillion webpages that already exist that explain how to do that – a forum focused on Notepad++ text editor is not the best place to look for details on the elementary learning of coding. Once you learn and understand coding in general, and compling-and-linking from the command line, then doing that from within Notepad++, using the information in the FAQ, is a piece of cake.

@PeterJones Thanks for that information, I’ll definitely turn on that setting. As far as searching goes, I hadn’t thought of using the term “backup.”

@PeterJones Ok, Reduce was checked. So I’m stuck with this.

It would be nice to control the font size and font name for the tab bar text.

Thanks!

Consider this closed.

@peklei said in UDL: Folding with Alt-0 no longer works correctly:

It would be interesting to know how this is implemented there and whether it can be recreated in a UDL definition.

In a UDL definition? No. Each built-in lexer has dedicated code for deciding where to fold (if that lexer has folding). The source code for UDL has a separate set of code, that is purely keyword-based.
From the “UDL definition” point of view, all you can do is set the open/middle/close keywords; you cannot change the logic from the UDL interface or config file. If you wanted to change the logic, it would require a change to the UDL source code, which requires a feature request

@Franz ,

Natively, no. Notepad++ doesn’t have a “filter” feature that just hides text without deleting it.

There might be some plugins that do a “filter”-like feature, but I don’t know which they are, and it would be doubtful if they’d work correctly with the Monitor (tail -f) feature of Notepad++. If someone else knows of a way, they can chime in.

As a workaround: assuming you have the logfile.log open as the current file (doesn’t need to be in “tail” mode, but it can be): Run > Run…

powershell -command "Get-Date -Format 'MM/dd/yyyy' >> '$(CURRENT_DIRECTORY)\filtered.log' ; Get-Content -Path '$(FULL_CURRENT_PATH)' -Wait | Select-String -pattern '^[AEOIU].*$' >> '$(CURRENT_DIRECTORY)\filtered.log';"

and then File > Open filtered.log, and set Monitor (tail -f).

This example filters your original logfile.log for any line in that starts with a vowel, and pipes it into filtered.log in the same directory; when you then open filtered.log in tail-mode, only the text that matches the filter will make it into filtered.log , which you are watching as it goes, so it gives you the basic effect, even though Notpead++ doesn’t do it natively.

If you want something other than “starts with a vowel”, change the '^[AEOIU].*$' from the command I gave to a valid powershell regular expression (make sure to keep it wrapped in single quotes, like the example regex was). (In this forum, we’re good at Notepad++ regular expressions; but powershell regex are not our area of expertise, so, if you need help with the powershell regex aspect, this forum probably isn’t the best place to ask)

@PeterJones Great catch! Thanks Peter!! It works! I didn’t notice the double .XML.

Just noticed your comment about the extensions. I keep it like that because I frequently use the search software Everything and several file conversion programs. I need to know what I’m dealing with while using them simultaneously.

The other reason I keep it hidden is so I don’t accidentally screw up the extension and can’t find the file. It’s happened to me several times. The only way that can happen is when I use Everything, However, it nicely only highlights the file name and not the extension, making it harder to unintentionally change the extension.

@Claudia-Svenson, I am wondering, What are you trying to achieve?

The reason I ask is that it’s possible to run a “portable” copy of Notepad++ without a doLocalConf.xml file.

You may want to review https://npp-user-manual.org/docs/config-files/#configuration-files-location.

If anyone else is interested in an AHK script that works, it’s simple enough:

#HotIf WinActive("Notepad++") XButton1::XButton2 XButton2::XButton1 #HotIf

@Martin-Neosel ,

Do you mean the orange bar on the left margin, as shown in this screenshot?
90102f0a-b5ce-44ca-9472-e03bf0a8d861-image.png

That’s the Change History. We have a FAQ that explains that feature, and how to turn it off (but also explains why it’s a good idea to leave it on, now that you know what it is).

@inkognito said in Remove "duplicate" lines based on only a specific part of the line:

How can I apply it to the text file without opening it in Notepad++?
Are there any corresponding options over the command line?

Two very leading but somewhat loosely defined questions.

Find in Files allows you to select a number of files based on filters, such as folders (and hidden & sub-folders), file type, partial filename. So the files are edited by Notepad++ (NPP) but don’t show in the NPP view(s). You could say they aren’t opened by NPP if you mean “do I see them in the NPP view”.

I am aware that there is the ability to have an “auto start” functionality upon loading NPP. The information is in the FAQ section here. So it uses the PythonScript plugin along with an “auto-start” script file called “startup.py”. Upon NPP loading it immediately starts processing the commands in this script file.

There is another PlugIn called NppExec and a post late last year suggested it might have a method on autostarting once NPP is loaded, see post #26006. Unfortunately there isn’t a lot else I have seen on NppExec, it doesn’t tend to get much exposure.

If you are referring to editing these files without NPP itself loading, then that is a whole other question which resides outside of this forum. Other command line editors such as AWK, SED, GREP etc might offer you that functionality but as I say that is not for this forum to answer. You would need to visit forums based on which ever editor you wish to use. The regular expression I provided might work as is in another editor, but likely would require some massaging to perform correctly.

@Manish-Patel,

Based on your description, I assume you are seeing something akin to
e28deaed-860a-4b30-9409-669bbcf0badd-image.png
… where the regex starts looking like a quote starts inside.

In that example, I also showed examples of how the escape is actually intentended to work: the “Escape” character escapes the various open/close symbols _when embedded between open/close symbols. So "In \" quotes", it properly treats the \" as being inside the string, not ending the string, and similarly for the single-quote example.

Since, based on your <Keywords...> line, you don’t have regex defined as delimiters, the parser is not in a mode where it knows it needs to escape them.

If you define regex wrappers as delimiters as well, like:
c4459c06-30a2-4102-b735-97449b2d96f2-image.png

… then you can get it to treat the regex as a string:
9c3810c4-bef3-4bb0-b24e-9443e312a000-image.png

The reason the quote isn’t starting a string inside the regex is because, by default, UDL doesn’t allow nesting of delimiters, unless you tell it to in the Stylers. This is more obvious if I do the same regex, but with the quotes not escaped:
186dddd5-94e5-4595-a12f-d3b85b0f2d2b-image.png

The quotes are still not treated as string-starters, because the regex delimiters were not defined to allow nesting of the string delimiters.

On the other hand, if you define Delimiter 5 to be [ and \ and ] and then in the Styler definition you also allow nesting of Delimiters 1 and 2:
f6821207-5207-450b-98b9-5168b42c7068-image.png

… then you can get another example, which shows quotes embedded in brackets, and escaped brackets:
347cbe63-ed9c-482b-8cbd-97498d8cc7f3-image.png

If you escape the quotes when inside brackets, they will not be recognized as embedded quotes anymore:
8ec9e14d-4e2d-48fe-848b-4b5bf5931cd6-image.png

So I believe these are the kinds of setups you will want. Defining the regex wrappers as delimiters as well should go a long way to giving you what you want, I think.
