beancount-language-server

A Language Server Protocol (LSP) server implementation for Beancount ledgers.

Features

• Definitions: commodities
• Diagnostics: if bean-check is on $PATH

Installation

Build the binary

cargo build --release

and copy it to your path, e.g.

cp target/release/beancount-language-server ~/.local/bin

Neovim LSP setup

The official nvim-lspconfig plugin is set up for the Javascript-based language server, so for now you have to add an alternative configuration entry like this in your init.vim:

local configs = require 'lspconfig.configs'
local util = require 'lspconfig.util'

configs["beancount_rs"] = {
  default_config = {
    cmd = {"beancount-language-server"};
    filetypes = {"beancount"};
    root_dir = function(fname)
      return util.find_git_ancestor(fname) or util.path.dirname(fname)
    end;
  };
  docs = {
    description = "A Beancount language server";
    default_config = {
      root_dir = [[root_pattern("elm.json")]];
    };
  };
}

local nvim_lsp = require('lspconfig')
nvim_lsp.beancount_rs.setup({})

beancount-language-server's Issues

Load included ledger data recursively

Replace manual node walking with queries

Queries are more powerful and much easier to understand. So let's do that instead.
