I created this project for my own use, and as a means to develop proficiency in Rust and Clojure. It is now at the stage where it could be useful for others, and my intention is to further develop it so it becomes increasingly useful. I am really enjoying being able to query my accounts from a Clojure REPL.And despite the current prevalence of AI code-generation, this was created by my own bare hands, quite slowly. All feedback welcome, most especially from anyone trying it out.

Could you build this?
Partial While the basic CLI and data structures for double-entry bookkeeping can be scaffolded, correctly implementing the full Beancount specification requires complex booking algorithms, inventory lot resolution, and formal query language parsing.
What it would actually take: A production version requires an AST parser for Beancount's plain-text grammar, an exact-precision decimal arithmetic ledger engine, and complex inventory matching algorithms (FIFO, average cost lot tracking). The implementation typically relies on Rust for performance and memory safety, with foreign function bindings or a Clojure host for the interactive query REPL. Developing and validating these accounting invariants against edge cases requires specialized domain expertise in accounting mechanics and formal language parsers.
