Currently https://github.com/dail8859/NotepadNext/blob/master/src/NotepadNext/icons/newfile.ico only has up to 48x48 and even that is a bit blurry since it was created from a 16x16 png

Hello, congratulations on this interesting project.

Is it compatible with Notepad++ plugins, and if not is there any plan to support them in the future?

Thank you

Add functionality to search through files. The Find dialog needs alot of attention prior to that. Also it would be worth first implementing the search results docked dialog for searching since that would be needed also.

https://www.incrediblelab.com/how-to-replace-notepad-with-notepad-plus/

Example to replace with Notepad++:

reg add "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\notepad.exe" /v "Debugger" /t REG_SZ /d ""%ProgramFiles(x86)%\Notepad++\notepad++.exe" -notepadStyleCmdline -z" /f

When using the context menu from Explorer, opening a file still has the New 1 file open and doesnt focus on the expected file.

Checking the latest artefact from AppVeyor, v0.3.0.68:

> Get-PESecurity -File .\NotepadNext.exe

ARCH             : AMD64
DotNET           : False
ASLR             : True
DEP              : True
Authenticode     : False
StrongNaming     : N/A
SafeSEH          : N/A
ControlFlowGuard : False  <-- CFG
HighentropyVA    : True

Could you please try building with the /guard:cf?

During installation or uninstallation, detect if the application is running. Warn the user to kill it, or wait for it to finish or something.

Scintilla v5.1.5 was just released.

See: https://www.scintilla.org/ScintillaDoc.html#SCI_SETHIGHLIGHTGUIDE

https://nsis.sourceforge.io/Docs/AppendixC.html#multipleinstances

 System::Call 'kernel32::CreateMutex(p 0, i 0, t "myMutex") p .r1 ?e'
 Pop $R0
 
 StrCmp $R0 0 +3
 MessageBox MB_OK|MB_ICONEXCLAMATION "The installer is already running."
 Abort

Looks like it has been actively developed. LuaBridge might not be a long term solution but still worth keeping updated since it is easy to integrate.

https://github.com/alex-spataru/QSimpleUpdater looks promising

Cursor location is useful, would be nice to also so the selection range. Possibly a lighter color.

Any idea about this??

Middle-mouse click on a editor tab should behave the same as left-clicking the x icon.

There was a lively discussion happening at notepad-plus-plus/notepad-plus-plus#8248 (also, see these feature proposals: notepad-plus-plus/notepad-plus-plus#8278, notepad-plus-plus/notepad-plus-plus#8247)

Would you be interesting in accepting this in NotepadNext?

Community discussion: https://community.notepad-plus-plus.org/topic/12722/survey-incremental-search-usefulness

• Accept license in installer
• Make sure it is in the zip release

Integrate https://github.com/editorconfig/editorconfig-core-qt

Some restructuring needs done to the code to be able to flexibly support this. Currently EOL, tab settings, etc are hard coded.

Wait till a release is made that officially supports styling the focused DockWidget

Very few settings are currently saved on exit (recent files, gui state)

Update once githubuser0xFFFF/Qt-Advanced-Docking-System#216 is closed/merged

1. Create new file
2. Type some text
3. Save file
4. Give it a name
5. Tab title doesnt update, e.g. still says "New 1"

Nice to see this editor,
1、“Find in files” has a menu item, but can't open the operational panel
2、Encoding is not started
3、Golang is not supported.

067e3f8 enables per-user and per-machine installation. Think it is worth looking into https://github.com/Drizin/NsisMultiUser as an alternative to this as it has better support.

Evaluate Qt 6+ since the open source channel is stuck on 5.15.2

I think most of the external dependencies are Qt 6 compatible but need to actually try it out and see what needs done.

Ideally support but Qt 5.15 and 6+ if possible.

When nothing is selected delete works as expected.

When text is selected delete seems to have no effect.

Add ability to split an editor horizontally similarly how Visual Studio does it:

https://stackoverflow.com/a/42132117

Need to handle the zip deployment differently.

• Potentially the zip deployment could not check for auto-updates at all. (installer could add registry entry to disable checks)
• Auto updater could read a different entry in the updates.json file (e.g. 'windows-zip') and either download the zip for the user or just open up the github releases page.

Thoughts?

Current implementation of QtSingleApplication seems outdated and not being developed, plus missing Qt6 support. See if it can be replaced with https://github.com/itay-grudev/SingleApplication

Some languages (especially when no language is assigned) doesn't need folding margins.

There is no file encoding support currently.

I don't understand file encodings enough to know I'm doing it correctly. The uchardet library is linked in which can detect file encodings.

I think this is what is needed: https://docs.microsoft.com/en-us/windows/win32/shell/app-registration#using-the-applications-subkey

Something like:

[HKEY_CLASSES_ROOT\Applications\NotepadNext.exe\SupportedTypes]
".txt"=""
".py"=""
".c"=""
".cpp"=""

...and more as needed

Any idea to fix ?

Check if the application is already installed (e.g. by checking the registry) and prompt the user to uninstall it.

Just let you know that i have ported you're NotepadNext to good old OS/2
Yes its still alive

I used Qt v5.1.3 and GCC 9.2.0

The only trouble i came across where:

../../NotepadNext/IFaceTable.h:143:22: error: 'string' is not a member of 'std'

Fixed with by adding to IFacceTable.h #include

next error i faced where....

Maybe you have a better solution for this.

Language Inspector is not updating when a new file is opened, or when the language is changed. It only updates when switching to a preexisting editor.

Need to call QDir::toNativeSeparators() in more places such as recent file list, and tool tip for the editor tabs. Possibly other locations as well (dialog boxes?)

Though there is not a dedicated lexer, SciTE has some sort of Golang support by using the C++ lexer already implemented.

Could possibly also have a + button like Chrome does

1. Open multi-line document
2. Zoom out alot
3. Notice line margin width hasn't changed
4. Click somewhere else in the document to update the line number width
