bean-rs

Basic beancount clone (one day...) in Rust!

Still very very alpha and doesn't do most things that are necessary to be at all useful.

Python bindings are a WIP using PyO3;

The libraries:

• Rust: crates/bean-rs
• Python: pypi/bean-rs

Planned features:

• Parse beancount files using pest
• Stricter transaction keywords
• Propagate line numbers for debugging
• Calculate account balances
• Use proper Decimal handling
• Validate transactions against open/close directives
• Validate balance directives
• Pad statements
• Open/close with multiple currencies
• Add Python bindings
• Support includes
• Come up with a more punny name
• Currency conversions
• Price/cost and FIFO

(Deliberate) differences from beancount

• Postings can't omit the currency

Use from Rust
