Gooey is a Python decorator library that wraps argparse-based CLI programs and automatically generates wxPython GUI windows without code changes. It transforms command-line argument definitions into native desktop applications with form controls, progress tracking, and console output capture—turning a single-line decorator into a full UI layer. Single-package monolith: gooey/gui/application/ contains the main wxPython application loop, gooey/gui/components/ organizes UI widgets (header, footer, console, options), and gooey/gui/components/layouts/ manages form layout generation from argparse specs. Entry point is the @Gooey decorator in gooey/init.py that bootstraps the GUI around user code.

Python developers who maintain CLI tools and want to offer non-technical end-users a desktop GUI without rewriting the underlying logic; data scientists and IT professionals distributing scripts to colleagues who prefer graphical interfaces over terminal usage.

Actively maintained with 8+ release versions documented (1.0.3 through 1.2.0-ALPHA in docs/releases/), significant Python codebase (447KB), and established packaging infrastructure for Windows/macOS. Production-ready for standard use cases, though the ALPHA versioning suggests newer features are still stabilizing.

Single-maintainer project (chriskiehl) with wxPython 4.1.0+ as a hard dependency—wxPython is a heavy native binding library that can have platform-specific build issues and may drop support for older Python versions. Moderate dependency footprint (psutil, Pillow, pygtrie, colored) and risk of bitrot if wxPython API changes significantly; no visible CI/test suite in file list.

Version 1.2.0-ALPHA is in progress with focus on new features (richtext controls documented in docs/Using-Richtext-Controls.md, dynamic validation in Gooey-Options.md). TODO.md likely contains backlog; packaging templates for PyInstaller (docs/packaging/build-win.spec, build-osx.spec) suggest ongoing effort to ease distribution.

git clone https://github.com/chriskiehl/Gooey.git && cd Gooey && pip install -e . (editable install for development) or pip install Gooey (PyPI release). Minimal: from gooey import Gooey; @Gooey decorator your argparse main() and run.

Daily commands: No traditional dev server; runs as standalone wxPython application. For development: python -m gooey or directly instantiate @Gooey-decorated functions. Testing appears manual (no pytest/tox visible); run examples by executing decorated Python scripts directly.

• gooey/__init__.py — Main entry point and decorator that wraps Python CLI programs; every contributor must understand the @Gooey decorator API
• gooey/gui/application/application.py — Core GUI application lifecycle and event loop; handles window creation and main execution flow
• gooey/gui/processor.py — Bridges CLI argument parsing and GUI widget generation; critical for mapping argparse to UI components
• gooey/gui/bootstrap.py — Initializes the GUI framework and coordinates startup; essential for understanding how Gooey bootstraps itself
• gooey/gui/components/options/options.py — Renders and manages form widgets from parsed argparse arguments; core UI component generation logic
• gooey/gui/pubsub.py — Event publishing and subscription system for inter-component communication throughout the application
• gooey/gui/state.py — Centralized state management for GUI state, user inputs, and execution context

Add a new widget type for custom argument handling

1. Create a new widget class in gooey/gui/components/widgets/ inheriting from bases.BaseWidget (gooey/gui/components/widgets/bases.py)
2. Implement the getValue(), setValue(), and valueIsValid() methods for your widget type (gooey/gui/components/widgets/textfield.py)
3. Register the widget in options.py by adding a case to the widget factory logic (gooey/gui/components/options/options.py)
4. Create a corresponding validator in gooey/gui/components/options/validators.py if needed (gooey/gui/components/options/validators.py)
5. Test by specifying widget_name='YourWidget' in the @Gooey decorator for an argument (gooey/__init__.py)

Add a new layout style for organizing arguments

1. Create a new layout class in gooey/gui/components/layouts/layouts.py extending BaseLayout (gooey/gui/components/layouts/layouts.py)
2. Implement build() method to arrange options panels, sidebars, or tabs as needed (gooey/gui/components/layouts/layouts.py)
3. Register layout name in the layouts factory/dispatcher at the end of layouts.py (gooey/gui/components/layouts/layouts.py)
4. Use the layout by passing layout_type='YourLayout' to @Gooey decorator (gooey/__init__.py)

Add a new validation rule for argument values

1. Create a validator function in gooey/gui/components/options/validators.py (gooey/gui/components/options/validators.py)
2. Register the validator in the VALIDATORS map in the same file (gooey/gui/components/options/validators.py)
3. Update gooey/gui/validation.py if you need cross-field validation or async validation (gooey/gui/validation.py)
4. Reference validator in @Gooey via gooey_options={'validator': {'test': your_validator_func, ...}} (gooey/__init__.py)

Add a new message or string for internationalization

1. Add the message key and default English text to gooey/gui/lang/i18n.py (gooey/gui/lang/i18n.py)
2. Reference it in code using getText('your_key') from the i18n module (gooey/gui/lang/i18n.py)
3. Translation files are stored under gooey/gui/lang/ named by language code (e.g., es.py, fr.py) (gooey/gui/lang/__init__.py)

• wxPython — Cross-platform desktop GUI toolkit that provides native look-and-feel on Windows, macOS, and Linux without heavyweight runtime
• argparse — Python standard library module for CLI parsing; Gooey introspects argparse to auto-generate form widgets
• subprocess (Python stdlib) — Spawns and communicates with the user's original CLI program; allows Gooey to wrap any Python CLI without modification
• Pillow (PIL) — Image loading and processing for custom icons, headers, and visual assets
• psutil — undefined

wxPython is platform-specific (Windows/macOS/Linux require separate builds and binaries); subprocess target execution assumes the decorated function accepts sys.argv and is re-callable, so state mutations in the original function may cause issues on re-runs. JSON configuration mode (load_build_config) may differ from decorator args at runtime. Monospace font mode (monospace_display) affects only output console, not form labels.

• Decorator Pattern (Python) — Gooey's entire design is built on the @Gooey decorator wrapping user code; understanding decorator mechanics (closures, function wrapping, execution flow) is essential to extending or debugging Gooey behavior
• argparse Introspection — Gooey must parse the argparse.ArgumentParser object at runtime to extract argument names, types, help text, and choices; Gooey's core task is mapping argparse metadata to wxPython widgets
• Subprocess I/O Streaming — Gooey launches the decorated function as a subprocess and must capture and stream stdout/stderr in real-time to the console widget without blocking the GUI event loop; seen in gooey/gui/components/console.py
• wxPython Event Loop & Sizers — Gooey builds UI layouts using wxPython sizers (FlexGridSizer for form columns); developers must understand event-driven architecture and widget layout constraints to modify forms or add new controls
• JSON Serialization for GUI State — Gooey can dump and load UI configuration as JSON (dump_build_config/load_build_config parameters); understanding this stateless representation is key for advanced use cases like programmatic UI generation or cross-platform reproducibility
• Prefix Filtering (Trie-based Search) — gooey/gui/components/filtering/prefix_filter.py implements pygtrie for efficient argument filtering; relevant for UX optimization when CLIs have many options

• pallets/click — Alternative decorator-based CLI framework with built-in GUI plugins via click-shell; different philosophy but overlapping use case of reducing CLI boilerplate
• tiangolo/typer — Modern argparse replacement using type hints; some users prefer Typer + Gooey over raw argparse for cleaner CLI definitions
• pypa/setuptools — Packaging companion; Gooey users rely on setuptools/PyInstaller to bundle the GUI app as standalone executable for distribution
• wxWidgets/wxWidgets — Upstream C++ library that wxPython wraps; understanding wxWidgets architecture helps debug layout and widget issues in Gooey
• pyinstaller/pyinstaller — Deployment solution referenced in docs/packaging/; users package Gooey-decorated scripts with PyInstaller to create .exe/.app binaries

Add unit tests for gooey/gui/components/widgets/ core widget classes

The widgets directory contains core UI components (text_input.py, chooser.py, bases.py, checkbox.py, etc.) but there's no visible test suite. These are critical for ensuring GUI reliability across wxPython versions. Adding tests for widget initialization, event handling, and value binding would catch regressions early and give new contributors confidence in refactoring.

• [ ] Create tests/gui/components/widgets/ directory structure mirroring gooey/gui/components/widgets/
• [ ] Add unit tests for gooey/gui/components/widgets/core/text_input.py covering initialization, value getters/setters, and validation callbacks
• [ ] Add unit tests for gooey/gui/components/widgets/core/chooser.py covering dropdown population and selection events
• [ ] Add unit tests for gooey/gui/components/widgets/checkbox.py and counter.py with toggle/increment behavior
• [ ] Add pytest configuration (pytest.ini or pyproject.toml) and update CONTRIBUTING.md with test running instructions

Add GitHub Actions workflow for cross-platform GUI testing (Windows/macOS/Linux)

Gooey is a wxPython-based cross-platform GUI library, but there's no evidence of CI testing on multiple OSes. This is critical since wxPython behaves differently per platform. Adding a GitHub Actions workflow would catch platform-specific regressions and help new contributors validate GUI changes without owning multiple machines.

• [ ] Create .github/workflows/test.yml with matrix strategy for Windows, macOS, and Ubuntu runners
• [ ] Configure wxPython installation for each platform (noting Windows/macOS binary availability vs Linux compilation needs)
• [ ] Add test execution step using pytest pointing to tests/ directory
• [ ] Add optional smoke test: run a simple Gooey-decorated example script to verify GUI initialization
• [ ] Document in CONTRIBUTING.md that CI runs on all pull requests and local testing instructions

Document gooey/gui/components/options/validators.py with validation examples and extension guide

The validators.py module exists but there's no corresponding documentation file explaining how validation works or how users can extend it. The README mentions 'Dynamic Validation' but doesn't link to implementation details. This creates friction for contributors trying to add custom validators or understand validation flow.

• [ ] Create docs/Validation-and-Validators.md documenting built-in validators in gooey/gui/components/options/validators.py
• [ ] Add code examples showing: built-in validator usage, custom validator creation, and integration with widget options
• [ ] Document the validator API contract (input signature, return types, error message format)
• [ ] Link this new doc from README.md in the 'Dynamic Validation' section and from CONTRIBUTING.md
• [ ] Add inline docstrings to validator functions/classes in validators.py if missing

• Add unit tests for gooey/gui/components/options/validators.py—currently no test files visible; validators.py handles critical input validation and has no test coverage
• Document all Gooey-Options decorator parameters in docs/Gooey-Options.md with code examples—currently only mentioned in decorator docstring in gooey/init.py; many advanced_cols, required_cols, default_size options lack examples
• Create example scripts in examples/ directory for common use cases (file picker with argparse, dropdown selection with validation, progress bar with elapsed time)—README references these but file list shows no examples/ folder

The Gooey codebase has a moderate security posture with several concerns. The primary issues are outdated pinned dependencies (typing-extensions, mypy-extensions) that prevent automatic security updates, loose dependency version constraints that could introduce incompatible versions, and potential command injection risks in the CLI-to-GUI conversion mechanism. The lack of a security policy and absence of security headers/configurations are additional concerns. The rich text components warrant careful input validation. Recommendations include updating dependencies to latest versions with reasonable version bounds, implementing strict input sanitization for CLI argument processing, adding a SECURITY.md policy, and conducting regular security audits of subprocess handling.

• High · Outdated and Pinned Dependency Version — Dependencies/Package file (typing-extensions==3.10.0.2). The dependency 'typing-extensions==3.10.0.2' is pinned to a very old version (released in 2021). This version may contain known security vulnerabilities and is significantly behind the current releases. Pinned versions prevent automatic security updates. Fix: Update to the latest version of typing-extensions. Use flexible version constraints (e.g., 'typing-extensions>=4.0.0') to allow security patches while maintaining compatibility.
• High · Outdated and Pinned Dependency Version — Dependencies/Package file (mypy-extensions==0.4.3). The dependency 'mypy-extensions==0.4.3' is pinned to an old version from 2021. Pinned versions prevent automatic security updates and bug fixes. Fix: Update to the latest compatible version and use flexible version constraints (e.g., 'mypy-extensions>=0.4.3') to allow security patches.
• Medium · Potential Command Injection in CLI Processing — gooey/gui/cli.py, gooey/gui/application/application.py. The codebase converts arbitrary Python CLI programs into GUI applications (gooey/gui/cli.py, gooey/gui/application/application.py). If user input from GUI forms is passed to CLI commands without proper sanitization, this could lead to command injection attacks. The file structure suggests subprocess execution of wrapped CLI programs. Fix: Ensure all user inputs from GUI forms are properly validated and sanitized before being passed to subprocess calls. Use shell=False with subprocess and pass arguments as a list rather than a string. Implement strict input validation for all command-line parameters.
• Medium · Weak Dependency Management — Dependencies/Package file. Multiple dependencies lack upper version bounds (wxpython>=4.1.0, Pillow>=4.3.0, psutil>=5.4.2, colored>=1.3.93, pygtrie>=2.3.3, re-wx>=0.0.2), allowing installation of potentially incompatible or vulnerable future versions. Fix: Define reasonable upper version bounds for all dependencies to prevent breaking changes and ensure compatibility. Use tools like pip-audit to identify vulnerable transitive dependencies.
• Medium · No Security Policy Documentation — Repository root. The repository lacks a SECURITY.md file or security policy documentation for reporting vulnerabilities responsibly. Fix: Create a SECURITY.md file with clear guidelines for reporting security vulnerabilities, expected response times, and the process for patching.
• Low · Potential XSS Risk in Rich Text Components — gooey/gui/components/widgets/richtextconsole.py. The codebase includes rich text controls (gooey/gui/components/widgets/richtextconsole.py, docs/Using-Richtext-Controls.md) that may render user-provided content. If not properly escaped, this could pose an XSS risk in GUI contexts. Fix: Ensure all rich text content is properly sanitized and escaped before rendering. Implement input validation for any user-provided markup or rich text.
• Low · Deprecated wxPython Version Consideration — Dependencies/Package file (wxpython>=4.1.0). The minimum required wxPython version is 4.1.0 (released in 2020). Ensure the project is regularly tested with current wxPython versions to catch compatibility and security issues. Fix: Regularly update and test with the latest wxPython versions. Monitor wxPython security advisories and update promptly when issues are discovered.

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. Read in the suggested order before editing unfamiliar code. The reading-order list is computed from the actual import graph, not LLM guesses; reading bottom-up materially reduces wrong-edit risk.
3. 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.
4. Cite source on changes. When proposing an edit, cite the specific path/to/file.ext:Lstart-Lend you're reasoning about, the same way RepoPilot's own RAG cites code in https://repopilot.app/r/chriskiehl/Gooey.

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.

This artifact was generated by RepoPilot at a point in time. Before an agent acts on it, the checks below confirm that the live chriskiehl/Gooey repo on your machine still matches what RepoPilot saw. If any fail, the artifact is stale — regenerate it at repopilot.app/r/chriskiehl/Gooey.

What it runs against: a local clone of chriskiehl/Gooey — the script inspects git remote, the LICENSE file, file paths in the working tree, and git log. Read-only; no mutations.
