bblocks-projects 0.1.2

ONE Data Python project utilities - templates, tools, and workflows

bblocks.projects

ONE Campaign Python project utilities - create, update, and enhance Python projects with standardized templates and tools.

Installation

Use with uvx (recommended for one-off usage)

No installation required! Just use uvx:

uvx bblocks-projects my-awesome-project

Install persistently with uv

uv tool install bblocks-projects
bblocks-projects my-awesome-project

Install with pip/pipx

pipx install bblocks-projects
# or
pip install bblocks-projects

Usage

Create a New Project

Interactive (recommended):

bblocks-projects my-project

The tool will ask you questions to customize your project:

• Project name and description
• Project type (package or research)
• Author information
• License choice
• etc.

With options:

# Create a package project with defaults
bblocks-projects my-package --type package --defaults

# Create using a specific template version
bblocks-projects my-project --ref v1.0.0

# Override specific values
bblocks-projects my-project --data author_name="Jane Doe" --data author_email="[e-mail]"

Update an Existing Project

Keep your project in sync with the latest template improvements:

# Update from within your project directory
cd my-project
bblocks-projects update

# Or specify the path
bblocks-projects update --path /path/to/my-project

# Update to a specific template version
bblocks-projects update --ref v1.2.0

Add Components to Existing Projects

Add specific template features to your existing Python projects without full template adoption:

# List available components
bblocks-projects add --list

# Add pre-commit hooks
bblocks-projects add pre-commit

# Add multiple components at once
bblocks-projects add ruff ci pytest

# Add to a specific project
bblocks-projects add pre-commit --path /path/to/project

# Skip confirmation prompts
bblocks-projects add ruff --yes

# Force overwrite existing files
bblocks-projects add ci --force

Available Components:

• pre-commit - Pre-commit hooks with ruff and mypy
• ruff - Ruff linter and formatter with comprehensive rules
• ci - GitHub Actions CI workflow
• pytest - Pytest with coverage reporting (packages only)
• pypi-publish - GitHub Actions workflow for PyPI publishing (packages only)

What it does:

• Copies template files to your project
• Merges configurations intelligently into pyproject.toml
• Adds required dependencies
• Shows you exactly what will change before applying

Example workflow:

# You have an existing Python project
cd my-existing-project

# Add pre-commit hooks from ONE template
bblocks-projects add pre-commit
# ✓ Creates .pre-commit-config.yaml
# ✓ Adds pre-commit to dev dependencies
# Shows next steps: uv sync, pre-commit install

# Add CI workflows
bblocks-projects add ci
# ✓ Creates .github/workflows/ci.yml
# Shows next steps: commit and push to GitHub

# Add ruff configuration
bblocks-projects add ruff
# ✓ Adds [tool.ruff] config to pyproject.toml
# ✓ Adds ruff to dev dependencies
# Shows next steps: uv sync, ruff check

Options:

• --path, -p - Path to the project to update (defaults to current directory)
• --ref, -r - Update to specific template version
• --data, -d - Override template variables in KEY=VALUE format
• --skip-answered/--no-skip-answered - Skip or re-answer previously answered questions

Examples:

bblocks-projects update --path ../my-other-project
bblocks-projects update --no-skip-answered  # Re-answer all questions

add

Add specific template components to an existing project.

Arguments:
