Notepad3 is a free, open-source text editor with syntax highlighting for Windows. Built on the [Scintilla](https://www.scintilla.org/) editing component and [Lexilla](https://www.scintilla.org/Lexilla.html) lexer library, it has a small memory footprint while being powerful enough for professional programming and everyday text editing.
|
||
|
||
> Notepad3 is based on code from Florian Balmer's [Notepad2](https://www.flos-freeware.ch/notepad2.html) and XhmikosR's [Notepad2-mod](https://xhmikosr.github.io/notepad2-mod/). MiniPath is based on Florian Balmer's metapath.

|
||
|
||
## Building from Source
|
||
|
||
Notepad3 is built with **Visual Studio 2022** (toolset v143) targeting the Windows SDK.
|
||
|
||
```powershell
|
||
# Restore NuGet packages (required once)
|
||
nuget restore Notepad3.sln
|
||
|
||
# Build a specific platform
|
||
Build\Build_x64.cmd Release
|
||
|
||
# Build all platforms (Win32, x64, x64_AVX2, ARM64)
|
||
Build\BuildAll.cmd Release
|
||
|
||
# Or use MSBuild directly
|
||
msbuild Notepad3.sln /m /p:Configuration=Release /p:Platform=x64
|
||
```
|
||
|
||
Run `Version.ps1` before building to generate version headers from templates in `Versions\`.
|
||
|
||
## Configuration
|
||
|
||
Notepad3 uses a portable INI file for all settings. Press **Ctrl+F7** to open it directly in the editor.
|
||
|
||
- **UI settings** (`[Settings]`) — managed through Menu → Settings
|
||
- **Advanced settings** (`[Settings2]`) — edit manually; most require a restart
|
||
- **Status bar** (`[Statusbar Settings]`) — customize field layout, order, and width
|
||
- **Toolbar labels** (`[Toolbar Labels]`) — show function names next to icons
|
||
|
||
📖 **Full configuration reference:** [doc/Configuration.md](doc/Configuration.md)
