+# Copilot Instructions for Notepad3
+
+## Build
+
+Notepad3 is a Windows-only C/C++ application built with Visual Studio 2022 (toolset v145) and MSBuild. The solution file is `Notepad3.sln`.
+
+### Build commands
+
+```powershell
+# Full build (all platforms: Win32, x64, x64_AVX2, ARM64)
+Build\BuildAll.cmd [Release|Debug]
+
+# Single platform
+Build\Build_x64.cmd [Release|Debug]
+Build\Build_Win32.cmd [Release|Debug]
+Build\Build_ARM64.cmd [Release|Debug]
+Build\Build_x64_AVX2.cmd [Release|Debug]
+
+# MSBuild directly (used by CI)
+msbuild Notepad3.sln /m /p:Configuration=Release /p:Platform=x64
+
+# Clean
+Build\Clean.cmd
+
+# NuGet restore (required before first build)
+nuget restore
+```
+
+Default configuration is Release. The build scripts delegate to PowerShell scripts in `Build\scripts\`.
+
+### Versioning
+
+Run `Version.ps1` before building to generate `src\VersionEx.h` from templates in `Versions\`. Version format is `Major.YY.Mdd.Build` where the build number is persisted in `Versions\build.txt`.
+
+### Tests
+
+Tests live in `test\` and run via AppVeyor CI:
+
+```cmd
+cd test
+TestFileVersion.cmd       # Verifies built binary version info
+TestAhkNotepad3.cmd       # AutoHotkey-based GUI tests (requires AutoHotkey)
+```
+
+### CI
+
+GitHub Actions workflow at `.github/workflows/build.yml` builds all four platforms (Win32, x64, x64_AVX2, ARM64) in Release on `windows-2022` runners, triggered on push/PR to master.
+
+## Architecture
+
+Notepad3 is a Win32 desktop text editor built on the **Scintilla** editing component with **Lexilla** for syntax highlighting. It ships with two companion tools: **MiniPath** (file browser) and **grepWinNP3** (file search/grep).
+
+### Core modules (in `src\`)
+
+- **Notepad3.c/h** — Application entry point (`wWinMain`), window procedure, global state structs (`GLOBALS_T`, `SETTINGS_T`, `FLAGS_T`, `PATHS_T`)
+- **Edit.c/h** — Text manipulation (find/replace, encoding conversion, clipboard, indentation, sorting)
+- **Styles.c/h** — Scintilla styling, lexer selection, theme management
+- **Dialogs.c/h** — All dialog boxes and UI interactions
+- **Encoding.c/h** — Character encoding detection and conversion
+- **SciCall.h** — Type-safe inline wrappers for Scintilla direct function calls (avoids `SendMessage` overhead)
+- **DynStrg.c/h** — Custom dynamic wide-string type (`HSTRINGW`) with automatic buffer management
+- **PathLib.c/h** — Path manipulation via opaque `HPATHL` handle
+- **TypeDefs.h** — Core type definitions (`DocPos`, `DocLn`, `cpi_enc_t`), Windows version targeting, compiler macros
+
+### Vendored dependencies
+
+- **`scintilla\`** — Scintilla editor component with Notepad3-specific patches in `np3_patches\`
+- **`lexilla\`** — Lexilla syntax highlighting engine with custom patches
+- **`src\uchardet\`** — Character encoding detector
+- **`src\tinyexpr\` / `src\tinyexprcpp\`** — Expression evaluator for statusbar
+- **`src\uthash\`** — Hash table library (C macros)
+- **Boost Regex & IOStreams** — Managed via `vcpkg.json`
+
+### Syntax highlighting lexers (`src\StyleLexers\`)
+
+Each language has its own `styleLexXXX.c` file (~50+ languages). All lexers follow the `EDITLEXER` struct pattern defined in `EditLexer.h`:
+
+```c
+EDITLEXER lexXXX = {
+    SCLEX_XXX,          // Scintilla lexer ID
+    "lexerName",        // Lexilla lexer name (case-sensitive)
+    IDS_LEX_XXX_STR,    // Resource string ID
+    L"Config Name",     // INI section name
+    L"ext1; ext2",      // Default file extensions
+    L"",                // Extension buffer (runtime)
+    &KeyWords_XXX,      // Keyword lists
+    { /* EDITSTYLE array — must be last member */ }
+};
+```
+
+### Localization (`language\`)
+
+Resource-based MUI system with 27+ locales. Each locale has a directory `np3_LANG_COUNTRY\` containing resource `.rc` files. Language DLLs are built as separate projects in the solution.
+
+## Conventions
+
+### Code style
+
+- **Formatting**: LLVM-based `.clang-format` in `src\` — 4-space indentation, Stroustrup brace style, left-aligned pointers, no column limit, no include sorting
+- **Editor config**: `.editorconfig` enforces UTF-8/CRLF for source files, 4-space indentation for C/C++; Lexilla code uses tabs (preserved from upstream)
+- **String safety**: Uses `strsafe.h` throughout; deprecated string functions are disabled
+
+### Type conventions
+
+- Use `DocPos` / `DocPosU` / `DocLn` for Scintilla document positions and line numbers (not raw `int`)
+- Use `cpi_enc_t` for encoding identifiers
+- Use `HSTRINGW` and `HPATHL` (opaque handle types) instead of raw `WCHAR*` buffers for dynamic strings and paths
+- `NOMINMAX` is defined globally — use `min()`/`max()` macros or typed equivalents
+
+### Scintilla interaction
+
+Always use `SciCall.h` wrappers (e.g., `SciCall_GetTextLength()`) instead of raw `SendMessage(hwnd, SCI_XXX, ...)`. The wrappers use Scintilla's direct function pointer for performance.
+
+### Adding a new syntax lexer
+
+1. Create `src\StyleLexers\styleLexNEW.c` following existing lexer patterns
+2. Define `EDITLEXER` struct with lexer ID, name, extensions, keywords, and styles
+3. Register it in `Styles.c` lexer array
+4. Add localization string IDs to resource files
+
+### Global state
+
+Application state is centralized in global structs in `Notepad3.c` — `Globals`, `Settings`, `Settings2`, `Flags`, `Paths`. Prefer accessing these through their defined interfaces rather than adding new globals.
