Notepad++ v8

[donho]

Typing with a drop-down suggestion enabled in a large file became extremely slow with complete freezes while Notepad++ collects data for its suggestion drop-down. Reverted back to 7.9.5 and the problem goes away and there are again only occasional & barely noticeable (100ms or so) freezes for that.

Does anyone have the same issue here?

I assume by “suggestion drop-down”, that’s talking about the auto-completion on words feature.

I just took my portable v8-64bit, and created a file with about 4 million lines of the quick brown fox jumps over the lazy dog, for >100MB file. I made sure auto-completion was turned on I inserted a blank line at the top; when I started typing the, and it started doing background processing (presumably to do auto-completion)… a few minutes later (including starting this reply to this point), and it hadn’t finished bringing up the auto-completion popup

.

I took the same >100MB file and opened in a fresh portabl v7.9.5-64bit, and it took maybe 15sec or so in order to bring the auto-complete suggestion box – so slow, but not impossibly-so.

Notepad++ v7.9.5   (64-bit)

So yes, I can replicate the auto-completion problem – the v8 is significantly slower on large files.

I now see that the OP only had 4MB, not the >100MB of my file. In v7.9.5, I dropped my quick-brown-fox to 130k lines for 6MB, and typing quick or brown brought auto-complete within a fraction of a second like the OP. Taking the 6MB quick-brown-fox file to v8, typing the qu or br for quick or brown autocompletion took 10-15sec for it to try to auto-complete. Once again, even with the 4MB file, I was able to replicate that v8 was much slower than v7.9.5 on the auto-complete pulldown.

edit: the quick-brown-fox file was the only file open in either instance, so there wasn’t any other files being processed; and it was a .txt file, so no lexer was active.

Yes, but only for larger files than I typically use (which is probably why I never noticed it during testing v8). I tried with a 1M text file and didn’t notice anything. I tried with a 7M text file and autocomplete is very slow to respond - thus making typing of letters appearing slowdown considerably - in Notepad ++ v8, 64-bit. Trying with the same files on 7.9.5 64-bit - there is no difference between the 1M and 7M files - autocomplete is rather instantaneous.

Using these settings on both tests:

Cheers.

@Jurko-Gospodnetić Same to me - confirm problem 1. Version 8 is unusable in a 15000 lines text file. What a pity. May be the user can force N++ to index the document in a first step to come back to 7.x versions speed.

@PeterJones @Michael-Vincent @Toni-Felfe
All the test files you use are “Normal Text” (Language: None), right?

Yes, mine were.

Cheers.

[PeterJones]

@donho ,

Correct. They were .txt / None (Normal Text), so no lexer was active.

About the “dark mode” and plugins…
Guys, I’m not good in painting. Will there be a volunteer who would like to draw a “dark” version of NppExec’s Console icon?
Also, I have no idea how “transparency” works in icons. For example, NppExec’s Console icon on the docked panel has black lines at the top and at the bottom. I don’t know why so. Could anyone advise on this?

Is this autocompletion problem reprodicuble with Dark Mode OFF?

BTW, I think we should include the Dark Mode setting into the Debug Info as well.

My auto-complete experiments were in non-DarkMode only.

edit: I just tried in Dark Mode with the 6MB / 130k-line file, and it still took 10-15sec for qu to show the autocomplete box for quick

I did a screen-capture of the dark-mode toolbar, and then pasted in your existing icon – it doesn’t look too bad as is in the Dark Mode, so in theory, you could just use that. (I think you could put the same pointer in both the normal and dark-mode slots in the structure.)

For the transparency, I’m not really sure. I downloaded your ico file, and it properly has transparent pixels. And per @dinkumoil’s 2019 post here, the upper-left corner of the bitmap should be used as transparent color, so that should still work.

For example, NppExec’s Console icon on the docked panel has black lines at the top and at the bottom. I don’t know why so. Could anyone advise on this?

Regarding the black lines and docked icons, I looked through a couple of the icon files from Notepad++ docked panels, and icons used in other plugins for their docked panels, and also doing some screenshots of the docked tab bar – it looks like NPP is maybe using a 14x14 icon rather than 16x16 icon for the docked panel (and some of the plugins just provide a 12x12 icon for that). Maybe when Notepad++ is squishing your 16x16 to fit in the 14x14, it is either not handling transparency correctly, or it “averaged” from the transparent and non-transparent together, and decided that “black must be the best choice for those pixels”. So you might want to have a separate icon structure for the toolbar (16x16) compared to the icon you use for the docking icon (14x14 or 12x12).

I don’t have a system for compiling plugins and trying icons out live… but I might spend some time this evening making a few colored and maybe even “fluent-style” icons, and attach them to the NppExec issue #39 – since I’m the one who requested the change to your plugin, I should at least try to help. Warning: I have the know-how to create an icon file with the tools available to me; I do not guarantee it will “look good” in anyone else’s opinion. But I’ll try.

Yes, I do NOT use dark mode at all and I had the same long wait result with 8.0.

Regarding Auto-completion performance issue in v8, I’ve created an issue here:
https://github.com/notepad-plus-plus/notepad-plus-plus/issues/9975

The bug has nothing to do with dark mode, but related to the commit One button to compile them all (with auto-completion performance issue), since the previous commit Fix Copy command in Search result is available as there's no selection has no performance issue:

I have tried different compiling/linking optimization options with both Notepad++ project & Scilexer project in VS, but without remedying the problem.

I’ll keep looking for the solution, you’re welcome to check it as well. If there’s no solution, the following commit will be reverted :
https://github.com/notepad-plus-plus/notepad-plus-plus/commit/ab58c8ee3ed1b8f8fa84a06c0f7d304fb0f0cd76

and SciLexer.dll will separate from Notepad++ as before.

[Toni Felfe]

@donho i confirm!

[Toni Felfe]

@donho but it’s new with v8, something must have been changed

Quickly scanning, and this may be way off, so sorry in advance, but is it possible that Scintilla is being built in debug mode even in release? I just quickly looked at some changes, and see a line was commented out so maybe %scintilla_debug% will take on whatever it was previously assigned (maybe 1)? appveyor.yml :

...
(removed)    - if "%configuration%"=="Unicode Debug" set scintilla_debug=DEBUG=1
...
(added - note the # at the start of the line)
      #- if "%configuration%"=="Unicode Debug" set scintilla_debug=DEBUG=1
...
    - if "%Platform%"=="mingw-w64_810_X64" mingw32-make %scintilla_debug% -j%NUMBER_OF_PROCESSORS%
...

Notepad v8 64-bit

Dutch language

CTRL-O / Open prompts screen with text on ‘Open button’ = “Save”
Clicking the button to open a file works fine though.

That’s an interesting assumption. However, I rebuilt libSciLexer.lib x64 release then notepad++.exe to make sure there’s no problem of link, the result remains the same (libSciLexer.lib x64 Debug is not built therefore even absent from the disk).
