Load and convert DAT profile files +- `split-helix-yaml` - Split helix YAML configuration files + +These commands are available globally after installation and can be run from any directory: + +```bash +load-profile-from-dat +split-helix-yaml +``` + +## Quick Start + +### Package-Level Lazy Loading (New in v1.0.0) + +The package now supports **lazy loading** of geometry classes for better performance and cleaner imports: + +```python +# Simply import the package - classes are loaded on-demand +import python_magnetgeo as pmg + +# Load any YAML file with automatic type detection +# Classes are imported automatically as needed +obj = pmg.load("config.yaml") + +# Or access classes directly through the package +helix = pmg.Helix.from_yaml("H1.yaml") +ring = pmg.Ring(name="R1", r=[10, 20], z=[0, 10]) +insert = pmg.Insert.from_yaml("HL-31.yaml") + +# All geometry classes are available via the package namespace: +# pmg.Helix, pmg.Ring, pmg.Insert, pmg.Bitter, pmg.Supra, pmg.Screen, etc. +``` + +**Important**: When loading YAML files that use type tags (e.g., `!`), you need to ensure YAML constructors are registered first: + +```python +import python_magnetgeo as pmg + +# For YAML loading, register all classes first +pmg.verify_class_registration() + +# Now load YAML files +helix = pmg.load("helix.yaml") +``` + +**Why?** Lazy loading defers class imports until needed.
