Crate mollendorff_forge 

Forge - YAML formula calculator with Excel-style arrays

This library provides functionality to parse YAML files containing formulas, calculate them in dependency order, and update values.

Features

• Excel-style formulas in YAML files (SUM, AVERAGE, IF, etc.)
• Array model for Excel-compatible column-based data
• JSON Schema validation
• Type-safe homogeneous arrays (Number, Text, Date, Boolean)
• Excel import/export
• Multi-document YAML support

Example

use mollendorff_forge::parser::parse_model;
use mollendorff_forge::core::ArrayCalculator;
use std::path::Path;

let path = Path::new("model.yaml");
let model = parse_model(path)?;

println!("Tables: {}", model.tables.len());
println!("Scalars: {}", model.scalars.len());

let calculator = ArrayCalculator::new(model);
let result = calculator.calculate_all()?;
