Crate rustledger_wasm 

Beancount WASM Bindings.

This crate provides WebAssembly bindings for using Beancount from JavaScript/TypeScript.

Features

• Parse Beancount files (single and multi-file with includes)
• Validate ledgers
• Run BQL queries
• Format directives
• ParsedLedger — cached single-file with editor features (completions, hover, etc.)
• Ledger — cached multi-file with queries and cross-file completions

Example (JavaScript)

import init, { parse, validateSource, query } from '@rustledger/wasm';

await init();

const source = `
2024-01-01 open Assets:Bank USD
2024-01-15 * "Coffee"
  Expenses:Food  5.00 USD
  Assets:Bank   -5.00 USD
`;

const result = parse(source);
if (result.errors.length === 0) {
    const validation = validateSource(source);
    console.log('Validation errors:', validation.errors);
}
