Check out the [Getting Started Guide](GETTING_STARTED.md) for a beginner-friendly introduction!**

Overview¶

Rhiza is a CLI tool that helps you maintain consistent configuration across multiple Python projects by using templates stored in a central repository. It allows you to:

• Initialize projects with standard configuration templates
• Materialize (inject) templates into target repositories
• Validate template configurations
• Keep project configurations synchronized with template repositories

Installation¶

Using pip¶

pip install rhiza

To update to the latest version:

pip install --upgrade rhiza

Using uvx (run without installation)¶

uvx is part of the uv package manager and allows you to run CLI tools directly without installing them:

uvx rhiza --help

With uvx, you don't need to install rhiza globally. Each time you run uvx rhiza, it will automatically use the latest version available on PyPI. To ensure you're using the latest version, simply run your command - uvx will fetch updates as needed:

# Always uses the latest version
uvx rhiza init
uvx rhiza sync
uvx rhiza validate

If you want to use a specific version:

uvx rhiza@0.5.6 --help

From source¶

git clone https://github.com/jebel-quant/rhiza-cli.git
cd rhiza-cli
pip install -e .

Using uv (recommended for development)¶

git clone https://github.com/jebel-quant/rhiza-cli.git
cd rhiza-cli
make install

Verify installation¶

rhiza --help

Quick Start¶

1. Initialize a project with Rhiza templates:

cd your-project
rhiza init

This creates a .rhiza/template.yml file with default configuration.

1. Customize the template configuration:

Edit .rhiza/template.yml to specify which files/directories to include from your template repository.

1. Sync templates into your project:

rhiza sync

This fetches and copies template files into your project (first run) or applies updates via 3-way merge (subsequent runs).

1. Validate your configuration:

rhiza validate

This checks that your .rhiza/template.yml is correctly formatted and valid.

Commands¶

rhiza init¶

Initialize or validate .rhiza/template.yml in a target directory.

Usage:

rhiza init [OPTIONS] [TARGET]

Arguments:

• TARGET - Target directory (defaults to current directory)

Options:

• --project-name <name> - Custom project name (defaults to directory name)
• --package-name <name> - Custom package name (defaults to normalized project name)
• --with-dev-dependencies - Include development dependencies in pyproject.toml
• --git-host <host> - Target Git hosting platform (github or gitlab). Determines which CI/CD files to include. If not provided, will prompt interactively.
• --template-repository <owner/repo> - Custom template repository (format: owner/repo). Defaults to 'jebel-quant/rhiza'.
• --template-branch <branch> - Custom template branch. Defaults to 'main'.
• --path-to-template <directory> - Directory where template.yml will be created (defaults to <TARGET>/.rhiza). Use . to keep the file in the project root.

Description:

Creates a default .rhiza/template.yml file if it doesn't exist, or validates an existing one. The default configuration includes common Python project files like .github, .editorconfig, .gitignore, .pre-commit-config.yaml, Makefile, and pytest.ini.

You can customize the template source by specifying your own template repository and branch using the --template-repository and --template-branch options.

Examples:

# Initialize in current directory
rhiza init

# Initialize in a specific directory
rhiza init /path/to/project

# Initialize with GitLab CI configuration
rhiza init --git-host gitlab

# Use a custom template repository
rhiza init --template-repository myorg/my-templates

# Use a custom template repository and branch
rhiza init --template-repository myorg/my-templates --template-branch develop

# Initialize in parent directory
rhiza init ..

# Create template.yml in a custom directory
rhiza init --path-to-template /custom/rhiza

# Create template.yml in the project root
rhiza init --path-to-template .

Output:

When creating a new template file:

[INFO] Initializing Rhiza configuration in: /path/to/project
[INFO] Creating default .rhiza/template.yml
✓ Created .rhiza/template.yml

Next steps:
  1. Review and customize .rhiza/template.yml to match your project needs
  2. Run 'rhiza sync' to inject templates into your repository

When validating an existing file:

[INFO] Validating template configuration in: /path/to/project
✓ Found template file: /path/to/project/.rhiza/template.yml
✓ YAML syntax is valid
✓ Field 'template-repository' is present and valid
✓ Field 'include' is present and valid
✓ template-repository format is valid: jebel-quant/rhiza
✓ include list has 6 path(s)
✓ Validation passed: template.yml is valid

rhiza sync¶

Sync Rhiza configuration templates into a target repository using diff/merge, preserving local customisations.

Usage:

rhiza sync [OPTIONS] [TARGET]

Arguments:

• TARGET - Target git repository directory (defaults to current directory)

Options:

• --branch, -b TEXT - Rhiza branch to use [default: main]
• --strategy, -s TEXT - Sync strategy: merge (default) or diff
• --target-branch TEXT - Create/checkout a branch in the target repo for changes
• --help - Show help message and exit

Description:

Keeps your project in sync with the template repository:

• First run (no lock file): copies all template files and writes .rhiza/template.lock
• Subsequent runs: computes diff (base → upstream) and applies it via git apply -3 — local edits are preserved

.rhiza/template.lock is a YAML file that records the full state of the last sync:

sha: abc123def456789abcdef0123456789abcdef0123
repo: jebel-quant/rhiza
host: github
ref: main
include:
- .github/
- .rhiza/
exclude: []
templates: []
files:
- .github/workflows/ci.yml
- .rhiza/template.yml
- Makefile

Commit .rhiza/template.lock to version control — it is the anchor for incremental 3-way merges.

Examples:

# Sync templates (first time or update with 3-way merge)
rhiza sync

# Preview what would change (dry-run)
rhiza sync --strategy diff

# Sync from a specific branch
rhiza sync --branch develop

# Sync to a dedicated branch
rhiza sync --target-branch update-templates

Output:

[INFO] Target repository: /path/to/project
[INFO] Rhiza branch: main
[INFO] Sync strategy: merge
[INFO] Cloning jebel-quant/rhiza@main (upstream)
[INFO] Upstream HEAD: abc123def456
[INFO] First sync — copying all template files
[COPY] .github/workflows/ci.yml
[COPY] .editorconfig
[COPY] .gitignore
[COPY] Makefile
✓ Sync complete — 4 file(s) processed

rhiza materialize (Deprecated)¶

Deprecated. Use rhiza sync instead.

rhiza migrate¶

Migrate project to the new .rhiza folder structure.

Usage:

rhiza migrate [OPTIONS] [TARGET]

Arguments:

• TARGET - Target git repository directory (defaults to current directory)

Arguments:

• TARGET - Target git repository directory (defaults to current directory)

Description:

Migrates your project to use the new .rhiza/ folder structure for storing Rhiza state and configuration files. This command helps transition from the old structure where configuration was stored in .github/rhiza/ and .rhiza.history in the project root.

The migration performs the following actions:

1. Creates the .rhiza/ directory in the project root
2. Moves template.yml from .github/rhiza/ or .github/ to .rhiza/template.yml
3. Moves .rhiza.history to .rhiza/history
4. Provides instructions for next steps

The new .rhiza/ folder structure provides better organization by separating Rhiza's state and configuration from the .github/ directory.

Examples:

# Migrate current directory
rhiza migrate

# Migrate a specific directory
rhiza migrate /path/to/project

Output:

[INFO] Migrating Rhiza structure in: /path/to/project
[INFO] This will create the .rhiza folder and migrate configuration files
[INFO] Creating .rhiza directory at: .rhiza
✓ Created .rhiza
[INFO] Found template.yml at: .rhiza/template.yml
[INFO] Moving to new location: .rhiza/template.yml
✓ Moved template.yml to .rhiza/template.yml
✓ Migration completed successfully

Migration Summary:
  - Created .rhiza/ folder
  - Moved template.yml to .rhiza/template.yml
  - Moved history tracking to .rhiza/history

Next steps:
  1. Review changes:
       git status
       git diff

  2. Update other commands to use new .rhiza/ location
     (Future rhiza versions will automatically use .rhiza/)

  3. Commit the migration:
       git add .
       git commit -m "chore: migrate to .rhiza folder structure"

Notes:

• If files already exist in .rhiza/, the migration will skip them and leave the old files in place
• You can manually remove old files after verifying the migration was successful
• The old .rhiza.history file is removed after successful migration to .rhiza/history
• The original template file in .github/ is moved (removed from old location)

rhiza validate¶

Validate Rhiza template configuration.

Usage:

rhiza validate [TARGET] [OPTIONS]

Arguments:

• TARGET - Target git repository directory (defaults to current directory)

Options:

• --path-to-template DIRECTORY - Directory containing template.yml (defaults to <TARGET>/.rhiza). Use . to keep the file in the project root.

Description:

Validates the .rhiza/template.yml file to ensure it is syntactically correct and semantically valid. This performs authoritative validation including:

• Checking if the file exists
• Validating YAML syntax
• Verifying required fields are present
• Checking field types and formats
• Validating repository name format
• Ensuring include paths are not empty

Examples:

# Validate configuration in current directory
rhiza validate

# Validate configuration in a specific directory
rhiza validate /path/to/project

# Validate parent directory
rhiza validate ..

# Validate using a custom template directory
rhiza validate --path-to-template /custom/rhiza

# Validate with template.yml in the project root
rhiza validate --path-to-template .

Exit codes:

• 0 - Validation passed
• 1 - Validation failed

Output (success):

[INFO] Validating template configuration in: /path/to/project
✓ Found template file: /path/to/project/.rhiza/template.yml
✓ YAML syntax is valid
✓ Field 'template-repository' is present and valid
✓ Field 'include' is present and valid
✓ template-repository format is valid: jebel-quant/rhiza
✓ include list has 6 path(s)
  - .github
  - .editorconfig
  - .gitignore
  - .pre-commit-config.yaml
  - Makefile
  - pytest.ini
✓ Validation passed: template.yml is valid

Output (failure):

[ERROR] Target directory is not a git repository: /path/to/project

or

[ERROR] Template file not found: /path/to/project/.rhiza/template.yml
[INFO] Run 'rhiza sync' or 'rhiza init' to create a default template.yml

Architecture¶

Rhiza follows a modular architecture:

src/rhiza/
├── __init__.py         # Package initialization
├── __main__.py         # Entry point for python -m rhiza
├── cli.py              # Typer app and CLI command definitions
├── models.py           # Data models (RhizaTemplate)
└── commands/           # Command implementations
    ├── __init__.py
    ├── init.py         # Initialize template.yml
    ├── materialize.py  # Shared helpers (used by sync.py)
    ├── sync.py         # Sync templates (primary command)
    └── validate.py     # Validate configuration

Design Principles¶

1. Thin CLI Layer: Commands in cli.py are thin wrappers that delegate to implementations in commands/
2. Separation of Concerns: Each command has its own module with focused functionality
3. Type Safety: Uses pathlib.Path for file operations and Typer for type-checked CLI arguments
4. Clear Logging: Uses loguru for structured, colored logging output
5. Validation First: Always validates configuration before performing operations

Troubleshooting¶

Command not found: rhiza¶

Ensure the package is installed and your Python scripts directory is in your PATH:

pip install --user rhiza
# Add ~/.local/bin to PATH if needed
export PATH="$HOME/.local/bin:$PATH"

Template validation fails¶

Check that: 1. Your .rhiza/template.yml file exists 2. The YAML syntax is valid 3. Required fields (template-repository and include) are present 4. The repository format is owner/repo

Run rhiza validate for detailed error messages.

Git clone fails during sync¶

Ensure: 1. The template repository exists and is accessible 2. The specified branch exists 3. You have network connectivity to GitHub or GitLab 4. The repository is public (or you have appropriate credentials configured — see the Authentication Guide) 5. The template-host field matches your repository's hosting platform (defaults to "github")

Files not being copied¶

Check: 1. The paths in include are correct relative to the template repository root 2. The paths exist in the specified branch 3. Any exclude patterns are not filtering out wanted files

FAQ¶

Q: Can I use Rhiza with private template repositories?

A: Yes. Rhiza fetches templates by running git clone, so any credentials that allow Git to access the repository will work. See the Authentication Guide for step-by-step instructions on configuring GitHub Personal Access Tokens (PATs), SSH keys, and GitLab tokens — for both local development and CI/CD environments.

Q: Does Rhiza support template repositories hosted outside GitHub?

A: Yes! Rhiza supports both GitHub and GitLab repositories. Use the template-host field in your .rhiza/template.yml to specify "github" (default) or "gitlab".

Q: How do I use a GitLab repository as a template source?

A: Add template-host: gitlab to your .rhiza/template.yml file. For example:

template-repository: mygroup/myproject
template-host: gitlab
include:
  - .gitlab-ci.yml
  - Makefile

Q: Can I sync templates from multiple repositories?

A: Not directly. However, you can run rhiza sync multiple times with different configurations, or combine templates manually.

Q: What's the difference between rhiza init and rhiza sync?

A: init creates or validates the .rhiza/template.yml configuration file. sync reads that configuration and actually copies the template files into your project (and performs 3-way merges on subsequent runs).

Q: How do I update my project's templates?

A: Run rhiza sync — it applies a 3-way merge so your local changes are preserved.

Q: How do I update rhiza-cli itself?

A: The update method depends on how you installed rhiza:

• Using pip: Run pip install --upgrade rhiza
• Using uvx: No action needed! uvx automatically uses the latest version each time you run it. Just run your command: uvx rhiza <command>
• From source: Run git pull in the repository directory and then pip install -e . again

Q: Can I customize which files are included?

A: Yes, edit the include and exclude lists in .rhiza/template.yml to control exactly which files are copied.
