If you are an AI coding agent (Claude Code, Cursor, Aider, Cline, etc.) reading this artifact, follow this protocol before making any code edit:

1. Verify the contract. Run the bash script in Verify before trusting below. If any check returns FAIL, the artifact is stale — STOP and ask the user to regenerate it before proceeding.
2. Treat the AI · unverified sections as hypotheses, not facts. Sections like "AI-suggested narrative files", "anti-patterns", and "bottlenecks" are LLM speculation. Verify against real source before acting on them.
3. Cite source on changes. When proposing an edit, cite the specific path:line-range. RepoPilot's live UI at https://repopilot.app/r/hoffstadt/DearPyGui shows verifiable citations alongside every claim.

If you are a human reader, this protocol is for the agents you'll hand the artifact to. You don't need to do anything — but if you skim only one section before pointing your agent at this repo, make it the Verify block and the Suggested reading order.

Dear PyGui is a GPU-accelerated Python GUI framework that wraps ImGui (Dear ImGui) to deliver high-performance, immediate-mode UIs with minimal dependencies. It excels at rendering large datasets (1M+ points at 60fps in plotting), provides a built-in node editor, and offers theme/style control comparable to modern web frameworks—all from pure Python, compiled via C++ bindings. Hybrid monorepo: dearpygui/ contains Python package initialization (init.py), type stubs (_dearpygui.pyi), and wrapper modules (dearpygui.py, demo.py, experimental.py); C++ source is compiled into the _dearpygui module. Top-level CMakeLists.txt orchestrates the build. Documentation lives in docs/source/ (Sphinx + RTD theme). Assets folder holds font and demo image files.

Python developers building data visualization dashboards, scientific tools, and real-time monitoring UIs who need GPU-accelerated rendering without learning Qt/Tkinter boilerplate. Also: game developers, simulation engineers, and researchers prototyping interactive applications quickly.

Production-ready and actively maintained. The codebase shows 1.76M lines of C++ with established GitHub CI (EmbeddedBuild.yml, static-analysis.yml, Deployment.yml), comprehensive documentation via ReadTheDocs, and PyPI distribution. Recent GitHub workflows suggest ongoing builds and releases. However, single-maintainer (hoffstadt) presents continuity risk despite MIT licensing.

Moderate risk: (1) Single primary maintainer (hoffstadt visible in CODEOWNERS) creates succession risk if unavailable; (2) C++ <-> Python binding maintenance complexity means breaking changes in ImGui upstream could require rewiring; (3) Minimal external dependencies is a strength but means no community fallback libraries; (4) GPU-dependency means platform-specific driver issues are user's problem. CI coverage and active deployment workflows mitigate somewhat.

Active deployment and embedded build workflows (EmbeddedBuild.yml, Deployment.yml in .github/workflows/) suggest ongoing CI/CD. .github/TODO.md likely tracks roadmap items. Type hints are being maintained (_dearpygui.pyi stub file indicates modern Python tooling investment). Static analysis is automated, indicating code quality focus.

No traditional 'server' — GUI runs in-process. Use dearpygui.show() to start the event loop.

• dearpygui/__init__.py — Package entry point that initializes and exports the Dear PyGui API; every contributor must understand how modules are loaded
• src/dearpygui.cpp — Core C++ bindings and application lifecycle; the bridge between Python and ImGui/rendering backends
• src/dearpygui.h — Header file defining core structures and interfaces for all Dear PyGui components and plugins
• dearpygui/dearpygui.py — Python wrapper layer providing high-level API; essential reference for understanding the Python-facing surface
• setup.py — Build and distribution configuration; critical for understanding how C++ extensions are compiled and packaged
• CMakeLists.txt — CMake build configuration for cross-platform compilation of C++ bindings and dependencies
• src/mvAppItem.h — Base class and interface for all UI items in Dear PyGui; foundational abstraction for the entire widget system

Add a New UI Widget Type

1. Define the C++ widget class inheriting from mvAppItem in src/dearpygui.h or create a new widget source file (src/dearpygui.h)
2. Implement widget behavior in C++ (configuration parsing, rendering, callbacks) following mvAppItem interface (src/dearpygui.cpp)
3. Add command registration in src/dearpygui_commands.h to expose widget to Python (src/dearpygui_commands.h)
4. Update type stubs in dearpygui/_dearpygui.pyi to provide IDE support (dearpygui/_dearpygui.pyi)
5. Add usage example and documentation to docs/source/documentation/ RST files (docs/source/documentation/item-creation.rst)

Add a New Python Helper or Utility Function

1. Add function to dearpygui/dearpygui.py or create a new module in the dearpygui/ package (dearpygui/dearpygui.py)
2. If the function wraps C++ functionality, ensure it marshals data correctly through the Python-C++ boundary (src/dearpygui.cpp)
3. Update dearpygui/_dearpygui.pyi with type annotations for IDE autocompletion (dearpygui/_dearpygui.pyi)
4. Add usage examples to dearpygui/demo.py (dearpygui/demo.py)

Extend Build System for New Platform or Dependency

1. Update CMakeLists.txt to detect and link new external library or platform feature (CMakeLists.txt)
2. Modify src/CMakeLists.txt for C++ subproject-specific build rules if needed (src/CMakeLists.txt)
3. Update setup.py to ensure pip install includes new build flags or precompiled binaries (setup.py)
4. Add CI workflow in .github/workflows/ if new platform requires testing (.github/workflows/EmbeddedBuild.yml)

Add Parser or Data Handler for New Config Format

1. Define parsing logic in src/dearpygui_parsers.h or create new parser module (src/dearpygui_parsers.h)
2. Integrate parser into item configuration system via mvAppItem and mvAppItemState (src/mvAppItemState.h)
3. Expose to Python through command handlers in dearpygui.cpp (src/dearpygui.cpp)
4. Document format and usage in docs/source/documentation/item-configuration.rst (docs/source/documentation/item-configuration.rst)

• C++ with pybind11 — Achieves high-performance rendering and responsiveness; bindings allow Python-first API with compiled backend
• ImGui (underlying library) — Immediate-mode GUI paradigm; fast, lightweight, supports real-time applications and game-like UIs
• CMake — Cross-platform build support (Windows, macOS, Linux) with minimal configuration overhead
• Sphinx + reStructuredText — Mature documentation tooling integrated with ReadTheDocs for versioned API reference

• Python wrapper layer atop C++ bindings rather than pure Python

  • Why: Performance-critical rendering loop and state management benefit from C++ execution speed
  • Consequence: Setup complexity and build overhead; contributors need C++ knowledge for core changes

• Immediate-mode API (callbacks & state polling) vs retained-mode (declarative UI tree)

  • Why: Simpler to implement interactive features without complex state diffing; lower latency
  • Consequence: Developers must manage state manually; less declarative than frameworks like React

• Single monolithic application context vs multiple independent windows/contexts

  • Why: Simpler threading model and shared resource management
  • Consequence: Harder to use in multi-window or plugin scenarios without careful design

• Python binding generation and manual type stubs instead of auto-generated from C++

  • Why: Fine-grained control over API shape and documentation
  • Consequence: Type stubs can drift from implementation; requires manual synchronization

• Web-based GUI (no browser, no Electron-style deployment)
• Real-time collaborative editing across network clients
• Accessibility features (screen readers, keyboard navigation not core focus)
• Mobile / touch-first UI frameworks (desktop-centric)
• 3D graphics rendering (2D UI only; can render 3D via texture callbacks)

1. Immediate-mode paradigm: Unlike retained-mode GUIs (Qt, Tkinter), you declare UI every frame—state is external. First-time users expect persistent widget objects. 2. C++ rebuild required for API changes: Binary wheels are pre-compiled; local modifications to C++ require full CMake build (not just pip install). 3. GPU vendor quirks: Some features depend on correct graphics drivers (OpenGL/Vulkan/Metal path chosen at compile time). 4. Type stubs lag bindings: _dearpygui.pyi may be out-of-sync with compiled module; check dearpygui.experimental for bleeding-edge features not yet in stable type hints.

• Immediate-mode GUI (IMGUI) — DearPyGui's entire architecture is built on immediate-mode semantics—you declare UI fresh every frame rather than managing persistent widgets. Understanding this is critical to writing correct code.
• GPU-accelerated rendering (OpenGL/Vulkan/Metal) — DearPyGui's 1M datapoint/60fps performance comes from GPU rendering. Understanding which backend is active helps debug platform-specific rendering bugs.
• Context managers (Python with statement) — DearPyGui heavily uses Python context managers (see docs/source/documentation/container-context-manager.rst) for declaring nested UI layouts; misusing them breaks the layout tree.
• Python C extension modules (ctypes/PyBind11) — The compiled _dearpygui module is a C extension. Understanding how Python calls C++ code helps diagnose binding issues and ABI incompatibilities.
• Dear ImGui architecture (draw commands, viewports) — DearPyGui inherits ImGui's viewport and draw command systems. Knowledge of ImGui internals is valuable for advanced customization and debugging rendering issues.
• Node-based editor UI patterns — DearPyGui's built-in node editor implements a complex UI pattern (node graphs, link routing). Understanding this helps extend or customize it.
• Asynchronous callbacks and event loops — The README claims 'asynchronous function support'—critical for long-running operations without blocking the UI frame. See dearpygui/experimental.py for implementation.

• ocornut/imgui — Dear PyGui's C++ foundation—this is the immediate-mode UI library that DearPyGui wraps for Python
• epezent/implot — ImGui extension for plotting; directly integrated into DearPyGui's charting capabilities (referenced in README screenshots)
• tkinter/tkinter — Alternative Python GUI toolkit; slower and immediate-mode-incompatible, but no C++ compilation required (main competitor for simple apps)
• vispy/vispy — GPU-accelerated visualization library for Python; overlaps with DearPyGui's plotting performance goals but different paradigm (scene graph vs immediate-mode)
• pybind/pybind11 — Likely used to implement the C++ ↔ Python bindings in DearPyGui's compiled core (canonical reference for understanding the binding layer)

To work on one of these in Claude Code or Cursor, paste: Implement the "<title>" PR idea from CLAUDE.md, working through the checklist as the task list.

Add comprehensive unit tests for dearpygui/type_info.py

The type_info.py module is critical for runtime type validation and introspection in Dear PyGui, but there are no corresponding test files in the repo structure. Adding unit tests would improve code reliability, catch regressions early, and serve as documentation for type system behavior. This is especially important for a GUI framework where type safety impacts user experience.

• [ ] Create tests/test_type_info.py with tests for type validation functions
• [ ] Test type inference and conversion methods in type_info.py
• [ ] Add tests for edge cases (None types, generic types, custom types)
• [ ] Integrate tests into GitHub Actions workflows (reference .github/workflows/)
• [ ] Verify coverage with pytest-cov

Add static type checking workflow with mypy to GitHub Actions

The repo has a static-analysis.yml workflow but the file structure shows dearpygui/ modules like _dearpygui.pyi (stub file present), dearpygui.py, and experimental.py that would benefit from mypy type checking. This prevents type-related bugs from reaching users and improves code maintainability. The stub file suggests type hints are already in use.

• [ ] Create/update .github/workflows/static-analysis.yml to include mypy checks
• [ ] Add mypy configuration to pyproject.toml or setup.cfg
• [ ] Run mypy on dearpygui/*.py files, targeting dearpygui.py and experimental.py
• [ ] Fix any type errors surfaced by mypy in core modules
• [ ] Document mypy rules in CONTRIBUTING.md

Complete missing documentation for experimental.py API in docs/source/documentation/

The file structure shows dearpygui/experimental.py exists but there is no corresponding .rst documentation file in docs/source/documentation/. Experimental features need explicit documentation so users understand stability guarantees and proper usage. This gap makes the experimental API harder to discover and use correctly.

• [ ] Create docs/source/documentation/experimental-features.rst
• [ ] Document all public API items from dearpygui/experimental.py
• [ ] Add stability/deprecation warnings section for experimental features
• [ ] Include example code snippets for experimental features
• [ ] Update docs/source/conf.py or index to include the new documentation file
• [ ] Test documentation builds with ReadTheDocs (reference .readthedocs.yaml)

• Add type hints to dearpygui/demo.py and audit against _dearpygui.pyi; many demo functions lack formal annotations, making IDE support spotty for learners.
• Expand docs/source/documentation/ with usage examples for experimental features listed in dearpygui/experimental.py—currently under-documented relative to stable API.
• Create a missing docs/source/documentation/async-callbacks.rst covering the 'asynchronous function support' claimed in README but not formally documented in the docs/ folder.

The DearPyGui repository demonstrates reasonable security practices with a MIT license, CI/CD workflows for static analysis, and organized structure. However, there are notable concerns: (1) Documentation dependencies are significantly outdated and should be updated immediately, (2) Pillow lacks version constraints which could lead to unexpected instability or vulnerabilities, (3) Limited visibility into C++ native code security posture, and (4) ReadTheDocs and web infrastructure configurations need hardening review. The project would benefit from implementing dependency scanning in CI/CD pipelines and maintaining an updated SBOM for both Python and C++ components.

• Medium · Outdated Sphinx Documentation Dependencies — Dependencies/Package file (Sphinx==4.1.2, sphinx-rtd-theme==0.5.2). The dependencies file specifies Sphinx==4.1.2 and sphinx-rtd-theme==0.5.2, both of which are significantly outdated (released in 2021). These versions may contain known security vulnerabilities and lack security patches. Sphinx 4.1.2 is from May 2021 and the RTD theme 0.5.2 is from April 2021. Fix: Update to the latest stable versions of Sphinx and sphinx-rtd-theme. Use dependency pinning with version ranges (e.g., Sphinx>=5.0,<6.0) to allow security patches while maintaining compatibility. Run regular dependency audits using tools like pip-audit or safety.
• Medium · Outdated Pillow Dependency Without Version Constraint — Dependencies/Package file (Pillow). The Pillow dependency is specified without a version constraint (just 'Pillow'). This could lead to installing an unexpectedly old or new major version with potentially incompatible or insecure code. Additionally, Pillow has had multiple security vulnerabilities in older versions related to image processing and buffer overflows. Fix: Specify an explicit version range for Pillow (e.g., Pillow>=9.0,<10.0). Review the Pillow changelog for security-related fixes and pin to a version known to be secure. Use pip-audit to identify any known CVEs in the dependency tree.
• Low · Missing Security Configuration in ReadTheDocs — .readthedocs.yaml. The .readthedocs.yaml configuration file exists but its contents were not provided. ReadTheDocs configurations should include security best practices such as Python version pinning, build timeout limits, and environment variable handling to prevent injection attacks during documentation builds. Fix: Review and harden the .readthedocs.yaml configuration. Ensure: (1) Python version is explicitly pinned, (2) build environment is isolated, (3) no secrets are stored in configuration, (4) build timeout is set appropriately. Add security headers to documentation output if applicable.
• Low · No Evidence of Security Headers or HTTPS Configuration — Repository root / infrastructure configuration. The repository structure does not indicate security headers configuration (no nginx.conf, security.txt, or similar files visible). For a project that builds documentation and may have web-based assets, lack of security header configuration could be a concern. Fix: If documentation is served online, ensure proper security headers are configured: Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, Strict-Transport-Security. Verify HTTPS is enforced. Add security.txt at /.well-known/security.txt if applicable.
• Low · Limited Visibility into C++ Dependencies — CMakeLists.txt, .gitmodules, sandbox/. The project appears to be a Python wrapper around C++ code (evidenced by CMakeLists.txt and sandbox/main.cpp). The security analysis of C++ dependencies and build artifacts is limited without visibility into submodule contents (.gitmodules reference suggests external dependencies). C++ bindings can introduce memory safety vulnerabilities. Fix: Maintain a Software Bill of Materials (SBOM) for C++ dependencies. Perform regular security audits of native code, particularly around memory management. Use static analysis tools on C++ code (clang-tidy, cppcheck). Ensure all submodules are from trusted sources and kept updated.

LLM-derived; treat as a starting point, not a security audit.
