Crate rustledger_lsp 

Language Server Protocol implementation for Beancount.

This crate provides an LSP server for Beancount files, enabling IDE features like:

• Real-time syntax error diagnostics
• Autocompletion for accounts, currencies, payees
• Go-to-definition for accounts
• Hover information
• Document symbols (outline view)

Architecture

The server follows rust-analyzer’s architecture:

• Main loop: Handles LSP messages, applies changes, dispatches requests
• Query database: Salsa-inspired incremental computation
• Handlers: Process LSP requests against immutable snapshots

Example

fn main() -> std::process::ExitCode {
    rustledger_lsp::start_stdio().map(|()| std::process::ExitCode::SUCCESS)
        .unwrap_or(std::process::ExitCode::FAILURE)
}
