Transform this repository into a generic template for creating custom Funz model plugins. Based on the structure from fz-Scale, all Scale-specific code is removed and replaced with a mock implementation that remains installable and functional.

Structure

• .fz/models/Model.json - Generic model config with ${} variable syntax
• .fz/calculators/Model.sh - Mock calculator demonstrating execution pattern
• .fz/calculators/localhost_Model.json - Local execution config
• examples/Model/input.txt - Example input with variable substitution
• tests/test_plugin.py - Validates structure and fz integration
• .github/workflows/ci.yml - CI for JSON/shell validation and fz tests

Usage

import fz

# Parse variables from input
variables = fz.fzi("examples/Model/input.txt", "Model")
# {'x': ...}

# Compile with values
fz.fzc("examples/Model/input.txt", {"x": 3.14}, "Model", output_dir="out")
# Creates out/x=3.14/input.txt with ${x} replaced

Creating Custom Plugins

1. Rename Model.json → YourModel.json, update id field
2. Rename Model.sh → YourModel.sh, implement actual simulation calls
3. Update output section in model JSON with parsing commands for your output files
4. Update localhost_Model.json with new model mappings
