TurboGears 2 DevTools is a command-line toolkit that streamlines the development of TurboGears2 applications. Built on top of Gearbox, it helps you quickly scaffold new full-stack projects, generate extensions, manage database migrations, and launch interactive shells all from one unified interface.

• Quickstart: Scaffold a new TurboGears2 project in minutes.
• Extension Generator: Easily create and integrate TurboGears extensions.
• Database Migrations: Run migration commands for SQLAlchemy and Alembic effortlessly.
• Interactive Shell: Launch a shell preloaded with your app's context for rapid testing.
• Internationalization: Extract, initialize, update, and compile translation catalogs for your application.
• Agent Inspection: Inspect routes, models, templates, and scaffold templates with tginfo.
• Agent Skills: Install TurboGears-aware agent skills for AI coding assistants with gearbox tgskills.
• Gearbox Integration: Seamlessly work with Gearbox to serve and manage your applications.

Installation:

To install via pip, run:

pip install tg.devtools

For development and testing, install with extras:

pip install -e .[testing]

Creating a New Project:

Use the quickstart command to generate a new TurboGears2 full-stack application:

gearbox quickstart myproject

This creates a ready-to-run project with a standard directory structure and preconfigured settings. To start the newly created web application, follow the instructions in the project README.rst file.

• Generate a TG Extension:

  gearbox tgext
  

• Run Database Migrations:

  gearbox sqla-migrate
  gearbox migrate
  

• Launch an Interactive Shell:

  gearbox tgshell -c development.ini
  

• Inspect a Project for Agents and Scripts:

  gearbox tginfo summary --project . --config development.ini
  gearbox tginfo routes --project . --config development.ini --json
  gearbox tginfo models --project . --config development.ini --json
  gearbox tginfo templates --project . --config development.ini --json
  gearbox tginfo scaffolds --project . --config development.ini --json
  

  tginfo is read-only. It can import the target application just like gearbox tgshell or gearbox serve, but it does not run setup-app, migrations, database writes, or runtime requests as part of inspection. Loading application code can still execute project-defined import/startup side

effects, like any Python module.

• Install Agent Skills:

  gearbox tgskills
  

  By default this installs agent skills into the project-local .agents/skills/ directory. To opt in manually to Claude Code instead, run gearbox tgskills --claude; this installs only .claude/skills/. The skills tell agents to use gearbox tginfo for inspection, gearbox scaffold for creating conventional project files, and gearbox tgshell for runtime debugging with WebTest. To remove installed skills, delete the project-local .agents/skills/ directory or, for a Claude Code installation, the .claude/skills/ directory.

• Runtime Debugging:

  Use gearbox tgshell -c development.ini when you need the fully loaded application context for runtime checks, including WebTest requests. Runtime request debugging belongs in tgshell rather than tginfo.

• Safety Boundaries:

  tginfo inspection tools are read-only. Do not run setup-app, migrations, or other database-mutating commands as routine inspection; use them only when intentionally changing a development or test environment.

• Manage Translations:

  gearbox i18n extract
  gearbox i18n init -l es
  gearbox i18n update
  gearbox i18n compile
