Quickstart: Using the CLI

1. Prepare your metadata

• Prepare your metadata as Excel (.xls or .xlsx) or as a folder of CSV files (one CSV per sheet/table, filenames matching required sheets).
• (See metadata_ddl/ for example templates.)

2. Run TurboVault4dbt_cli

Basic usage:

# List all nodes in your metadata (Excel or CSV)
turbovault list -f xlsx path/to/your.xlsx
turbovault list -f csv path/to/your_csv_folder

# Generate dbt models for all nodes
turbovault run -f xlsx path/to/your.xlsx
turbovault run -f csv path/to/your_csv_folder

# Generate dbt models for selected nodes
turbovault run -f xlsx path/to/your.xlsx -s hub1 link1 sat1
turbovault run -f csv path/to/your_csv_folder -s '+hub1' '@sat1'

# Specify output directory
turbovault run -f xlsx path/to/your.xlsx --output-dir my_output_dir

Command reference:

• turbovault run -f {xls|xlsx|csv} <input> [-s <selectors>] [--output-dir <dir>]
  Generate dbt models for all or selected nodes.
• turbovault list -f {xls|xlsx|csv} <input> [-s <selectors>]
  List resolved nodes for a selector (dry run).

Arguments:

• -f, --format: Input format. Must be one of: xls, xlsx, csv
• input: Path to Excel file (.xls/.xlsx) or folder containing CSV files (for csv)
• -s, --select: (Optional) Node selectors (space-separated).
  Examples: hub1, +sat1, hub2+, @masat3
• --output-dir: (Optional) Output directory for generated files

Selector syntax:

• A+ — node A and all descendants
• +A — node A and all ancestors
• @A — node A, all ancestors, and all descendants
• Multiple selectors can be space-separated

Regression Testing

To run the regression test suite:

pip install -r requirements-test.txt
pytest tests/

• Add new test cases by creating folders in tests/ with input.xlsx and expected_output/.
• Negative test cases (expected failures) are also supported.
