v0.1.0 — Alpha: Persistent-State C++ Notebook

🛠 Version 0.1.0 — Alpha: Native Interactive C++ Notebook

This release marks the first public snapshot of cpp-notebook.
The system has been developed and used locally prior to this release; this version formalizes the project with a proper release process and documentation.

cpp-notebook is a native, interactive C++ notebook environment designed for exploratory programming with persistent state in compiled C++.

✨ What’s Included

Core Features

• Interactive notebook UI built with Dear ImGui and SDL2
• Cell-based C++ execution using a persistent global translation unit
• Variables, functions, and classes persist across cell executions
• Automatic regeneration and recompilation of program state on each run

Editor & Documentation

• Syntax-highlighted C++ editor (C++20-compatible, compiler-dependent)
• Markdown cells with live preview toggle
• Notebook-style keyboard shortcuts (e.g. Shift+Enter to execute)

Developer Tools

• Real-time variable inspection with type and value display
• Function and class outline panels
• Execution timing and structured error reporting
• Color-coded output for successful and failed executions

Build System

• CMake-based build system
• Supported platforms: macOS and Linux
• Dependencies: SDL2, Dear ImGui, ImGuiColorTextEdit

🚧 Known Limitations

• No interactive debugger (breakpoints or stepping)
• Limited multi-file or project-level support
• Compilation latency increases as the execution context grows
• No package or dependency manager integration
• Error messages lack precise source-to-cell line mapping

🎯 Planned for Future Releases

• Save and load notebook files (.cppnb format)
• Export notebooks to standalone .cpp or Markdown
• ImPlot-based visualization support
• Auto-completion and IntelliSense-style hints
• Faster compilation via precompiled headers
