Each subdirectory compiles into its own static library, keeping modules independent.

Building

Prerequisites

• CMake ≥ 3.16
• Qt6 (Widgets module)
• A C++17-capable compiler (GCC, Clang, MSVC)

Linux

cmake -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build -j$(nproc)
./build/BareCode

Windows (Visual Studio)

cmake -B build -G "Visual Studio 17 2022" -A x64
cmake --build build --config Release
build\Release\BareCode.exe

Windows (MinGW)

cmake -B build -G "MinGW Makefiles" -DCMAKE_BUILD_TYPE=Release
cmake --build build
build\BareCode.exe

Extending BareCode

Adding a new syntax highlighter

1. Create a subclass of SyntaxHighlighter in src/highlighter/.
2. Populate m_rules in the constructor (see CppHighlighter as a template).
3. Register the file extension(s) in HighlighterFactory.cpp.

No other files need to change.

Adding a new panel / plugin

1. Implement the IPlugin interface from src/core/IPlugin.h.
2. Create a QWidget-derived class for the UI.
3. Instantiate and wire it up in MainWindow.

Code Style

All code uses Allman brace style and C++17 throughout.
