bean-rs

Project paused until this PR in PyO3 (or something similar) gets merged.

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
