Beancount parser using Logos lexer and Winnow manual parser.

This crate provides a parser for the Beancount file format. It produces a stream of Directives from source text, along with any parse errors.

Features

• Full Beancount syntax support (all 12 directive types)
• Error recovery (continues parsing after errors)
• Precise source locations for error reporting
• Support for includes, options, plugins

Example

use rustledger_parser::parse;

let source = r#"
2024-01-15 * "Coffee Shop" "Morning coffee"
  Expenses:Food:Coffee  5.00 USD
  Assets:Cash
"#;

let (directives, errors) = parse(source);
assert!(errors.is_empty());
assert_eq!(directives.len(), 1);

rustledger-parser

Fast Beancount parser using Logos lexer and Chumsky parser combinators.

Features

• Full Beancount syntax support (all 12 directive types)
• Error recovery (continues parsing after errors)
• Precise source locations for error reporting
• SIMD-accelerated lexing via Logos

Architecture

Source (&str) → Logos tokenize() → Vec<SpannedToken> → Chumsky parser → Directives

Example

use rustledger_parser::parse;

let source = r#"
2024-01-15 * "Coffee Shop" "Morning coffee"
  Expenses:Food:Coffee  5.00 USD
  Assets:Cash
"#;

let result = parse(source);
assert!(result.errors.is_empty());
assert_eq!(result.directives.len(), 1);

Cargo Features

• rkyv (default) - Enable rkyv serialization for binary caching
