🚀 CLI Quick Reference

Stouputils provides a powerful command-line interface. Here's a quick example for each subcommand:

# Show version information of polars with dependency tree of depth 3
stouputils --version polars -t 3

# Run all doctests in a directory with pattern filter (fnmatch)
stouputils all_doctests "./src" "*_test"

# Repair a corrupted/obstructed zip archive
stouputils repair "./input.zip" "./output.zip"

# Create a delta backup
stouputils backup delta "./source" "./backups"

# Build and publish to PyPI (with minor version bump and no stubs)
stouputils build minor --no_stubs

# Generate changelog from git history (since a specific date, with commit URLs from origin remote, output to file)
stouputils changelog date "2026-01-01" -r origin -o "CHANGELOG.md"

🔧 Installation

pip install stouputils

✨ Enable Tab Completion on Linux (Optional)

For a better CLI experience, enable bash tab completion:

# Option 1: Using argcomplete's global activation
activate-global-python-argcomplete --user

# Option 2: Manual setup for bash
register-python-argcomplete stouputils >> ~/.bashrc
source ~/.bashrc

After enabling completion, you can use <TAB> to autocomplete commands:

stouputils <TAB>        # Shows: --version, -v, all_doctests, backup
stouputils all_<TAB>    # Completes to: all_doctests

Note: Tab completion works best in bash, zsh, Git Bash, or WSL on Windows.
