@User-Name said in Problem with big files (50+MB):

For example 300MB c++ file I can’t replace any text. It caused 50 second pause… I need just disable c++ language and set as text ?

It’s what, more than 5 million lines of code (LOC) to get 300MB of source code even for dense code? All in one file? Yikes, talk about a maintenance nightmare!

I ran some experiments with a dummy c++ that looked like

#include <stdlib> int main() { return 0; } int dummy(void) { return 32; } int dummy(void) { return 32; } int dummy(void) { return 32; } ...

… with enough copies of dummy to get about 1M LOC for about 32MB file length.

In Language=C++, a search-and-replace for 32; to 23; took 2-5min. Switching to Language=None/Normal Text and replacing the other way dropped to 1-2min. For my 8-core CPU, it was pegging one of the 8 cores at 100%, whereas the other cores were all sane usage levels. (My guess is that the search-and-replace is implemented in a single thread – at the scintilla/boost level, so not something that Notepad++ source code could change) because it’s a linear activity, so it doesn’t make good use of multiple cores)

Huge files are hard to handle, especially in applications like Notepad++ that keep the whole file open in a single buffer; it makes for large memory requirements and for large cpu requirements when doing whole-file activities. Turning off the lexer (Language menu) and not using View > Function List feature will both speed things up, as will not having plugins working in the background. But at hundreds of megs, it will still be slow, and probably slower than you would like.

I cannot imagine a corporate code-style-guide that would allow a single source file to be 300MB / 5M LOC. Even if filesize or LOC-per-file aren’t mandated or given guidelines, I cannot imagine maintaining a single file that has grown that big – whether in a corporate situation or in a personal or open source project.

As a bit of advice, I would recommend, for the long term, refactoring that code into multiple files, which will be easier to maintain. If it’s mandated by management to not spend time refactoring, explain to them that even activities like simple search/replace calls will take 5 minutes each, and that it can really add up. If they still won’t approve the time to refactor, I feel sorry for you.

If you’re stuck with 300MB source code, I might recommend a streaming-style search and/or search-and-replace command-line utility, rather than Notepad++, so it doesn’t have to be all in memory at the same time. Gnuwin32 project on SourceForge has functional versions of grep for searches and sed for search/replace, which I use when I don’t want to load the whole file into memory (I like those because I have a lot of linux experience with those tools, and these are gnu-compatible versions, old but functional enough for me). Or the windows powershell command-line-environment has some good command-line tools, but I am not a powershell expert, so cannot recommend large-file or multi-file search-and-replace syntax. And support for grep/sed and/or powershell is not on-topic for this forum, so you’d have to find help elsewhere.

@dinkumoil said in Non-unicode encodings discussion:

for example CharTableGenerator.vbs

For Pythonists that might want to generate the same data, here’s something short to make them feel comfortable:

number_list = list(range(128, 255 + 1)) with open('CharTable.txt', 'wb') as f: f.write(bytearray(number_list))

@Todd-Hoatson said in Strange behavior of Find All in Current Document with Regular Expression:

I didn’t realize that there is no automatic update feature in N++, so I didn’t think my version was so back-level. (Is it because I am using N++ portable?)

The portable instance does not enable the auto-updater, because the auto-updater downloads the installer, which would really confuse users.

If you’re unsure about the version, you can always look here in the Announcements thread, or at the official downloads page, or at the latest github release for the truly most-recent release… Or you can look at the same URL as the updater uses (https://notepad-plus-plus.org/update/getDownloadUrl.php) to see what version is being pushed to the updater as “most recent” (that XML at that URL only gets updated once the developer is convinced a release is stable enough to go to auto-update)

@Don-Moore ,

Go to Settings > Preferences > Language, then move the unused languages to the “Disabled Items” side (docs). This has the primary effect of hiding those language types from the Language menu, but it also has the secondary effect of removing those languages from the SaveAs list as well, which is what you want.

Also, if you select the Language entry before doing the Save/SaveAs action, it will automatically select the right entry from that drop-down.

Altnerately, if you have Settings > Preferences > MISC > Set save dialog extension to *.*, then you can just type the extension you want, and that extension will be applied and Notepad++ will automatically assign that file to the right Language menu entry, just like when you load a file with that extension.

@Alan-Kilborn hash match n all? dont understand it. will have to keep playing around and see i suppose. for now im “locked-in” to downloading the 7z variant lol.

@Jesper-Knudsen Please make this a separate post and tag the dev directly. I see myself using macbooks in the future and np++ on macos would be a goddamn treat

Not exactly what you are looking for, but do you know the
BetterMultiSelection plugin?
It could be an alternative in the way you format your code.

@John-Thompson-0

So what you’ve been given to solve your problem is one more most basic and core substitutions of this type that you can do.
You can see the power of it now, I’m sure.
Do yourself a favor and acquaint yourself with other similar techniques buy having a read HERE.

I do understand your point. My old business partner and best friend for 20+ years was a programmer and I just could never get my head around it. Like, I can decipher a lot of what’s in the line but to sit down and write it myself? no way. But I suppose if I just started doing it I could. I mean isn’t that how most people learned html and css? I know it’s how I did. back 25 years ago.

It’s been hard to get it. I’ve tried taking jquery courses and basic JavaScripting and it just never ‘took hold’ and got me interested. I suppose it’s because I never really ‘had’ to learn that like I did markup etc.

@Anthony-Blinco,

@Alan-Kilborn said in Is it possible to map multiple keys to notepad++ functions?:

Regarding editor.search() – which is proper for this thread since we’ve been discussing PythonScript – why not just move your caret to an instance of that in your text and invoke Context-Help from the PythonScript menu, right in Notepad++ ?

Am i looking at the right one

http://npppythonscript.sourceforge.net/docs/latest/scintilla.html#helper-methods

I’d give that a “no”.

Specifically, the old sourceforge copy of the documentation is severely out of date.

When you install PythonScript, it also installs a local up to date version of the PythonScript documentation, which can be accessed through Notepad++ menu Plugins > PythonScript > Context-Help (and, as @Alan-Kilborn mentioned, if your caret is on the editor.search() command, it should open the help to the right place). Use that for all documentation needs on PythonScript. But yes, it is in the helper-methods section of the editor object documentation.

Based on the link that @mere-human found, Admin Notepad++ may be able to get drag and drop messages by disabling filters with a call to ChangeWindowMessageFilterEx.

So there is point to file an issue.

@Ekopalypse

Well, I guess.
Sometimes there’s an art to data creation, though.
For instance, perhaps really long lines impact how fast something will run.
Perhaps the ratio of empty to non-empty lines makes a difference.
Perhaps…perhaps…perhaps…

I suppose it would have been best to have the OP’s data file, since it was the one that had the original complaint…

The explanation, solution and follow-up with the issue was suggested at Github, and ended up with the creation of two backup directories on the cloud for my two user names. All working well now. :)

I thought so. Thanks for your help yet again.

That is super helpful. Thanks you guys so much!!

Thank you very much. I will check that out

Thank you. I will have a look at that

@scorpcat007 said in is there a way to download the user manual?:

guess they closed the conversation. :(
never understood why forums are in such a rush to close conversations. seems like this is still relevant.

As one of the people involved in npp-usermanual issue#163, who put a lot of effort into solving the problem, and convincing the owner to incorporate the fix, so that the zipfile of usermanual will be downloadable for this and every future version of the Notepad++ user manual, I am rather frustrated that you would look just the word “closed” on the issue and thus complain here, without also looking over at the “accepted” label that is plainly visible on the same page:
dfc70801-7f21-402e-b2be-25042641dd6b-image.png

… and without reading down to the end, where you can see links to the three pull requests that went about implementing the request:
35a557f4-d9e3-4129-af67-27fad8a6cb0f-image.png

… or seeing the mention of the issue where the usermanual for Notepad++ v7.9.5 was released to the npp-user-manual.org website:
4856b40e-9f05-4de9-b619-70e40542c3d5-image.png

We weren’t in a rush to close the conversation… we were in a rush to solve your problem, and did our best to implement the requested feature. And once we did, and only then, did we close the request. The reason we closed the issue is because the feature was given to you, and had been published to the live website, as Alan linked.
