Examples

# Or with JSON output for programmatic use
cli-anything-audacity --json project new -o myproject.json
Interactive REPL Session
Start an interactive session with undo/redo support.
cli-anything-audacity
# Enter commands interactively
# Use 'help' to see available commands
# Use 'undo' and 'redo' for history navigation
Export Project
Export the project to a final output format.
cli-anything-audacity --project myproject.json export render output.pdf --overwrite
State Management
The CLI maintains session state with:
- Undo/Redo: Up to 50 levels of history
- Project persistence: Save/load project state as JSON
- Session tracking: Track modifications and changes
Output Formats
All commands support dual output modes:
- Human-readable (default): Tables, colors, formatted text
- Machine-readable (
--jsonflag): Structured JSON for agent consumption
# Human output
cli-anything-audacity project info -p project.json
# JSON output for agents
cli-anything-audacity --json project info -p project.json
For AI Agents
When using this CLI programmatically:
- Always use
--jsonflag for parseable output - Check return codes - 0 for success, non-zero for errors
- Parse stderr for error messages on failure
- Use absolute paths for all file operations
- Verify outputs exist after export operations
