Lazyvim (neovim) configuration for hledger

General

I decided to move slowly from emacs to neovim because I feel more confortable to modal editing because as Linux admin I use vi/vim/neovim everyday. I chose the lazyvim distribution for neovim and I would like to share with you my configuration for hledger files.

Contents of the file $HOME/.config/nvim/lua/plugins/hledger.lua:

return {
  {
    "ledger/vim-ledger",
    version = false,
    ft = "ledger",
    init = function()
      vim.g.ledger_bin = "hledger"
      vim.g.ledger_fuzzy_account_completion = 1
      vim.g.ledger_date_format = "%Y-%m-%d"
      vim.g.ledger_align_at = 70
    end,
    opt = {},
  },
  {
    "saghen/blink.cmp",
    opts = {
      sources = {
        compat = {},
        default = { "lsp", "path", "snippets", "buffer", "omni" },
      },
    },
  },
  {
    "nvim-treesitter/nvim-treesitter",
    opts = {
      ensure_installed = {
        "ledger",
      },
    },
  },
  {
    "mfussenegger/nvim-lint",
    opts = {
      events = { "BufWritePost", "BufReadPost", "InsertLeave" },
      linters_by_ft = {
        ledger = { "hledger" },
      },
      linters = {},
    },
  },
  {
    "stevearc/conform.nvim",
    opts = {
      formatters_by_ft = {
        ledger = { "trim_newlines", "trim_whitespace" },
      },
    },
  },
}

Comments of my configuration:

  • I use vim-ledger plugin because it provides alignment (:LedgerAlign and :LedgerAlignBuffer commands) and ommicompletion for accounts and descriptions.
  • I configure the blink.cmp completion plugin of lazyvim to use ommnicompletion provided by vim-ledger.
  • I configure the nvim-treesitter treesitter plugin of lazyvim to download the ledger grammar to have syntax highlighting and folding.
  • I configure the nvim-lint linter plugin of lazyvim to apply the hledger linter to ledger files.
  • I configure the conform.nvim formatter plugin of lazyvim to trim newlines and whitespaces of my ledger files.

Other comments:

  • The completion is done by the old vim-ledger plugin and I did not find any more recent completion plugin.
  • I would like a more powerful formatter for hledger files which would provide also alignment and sorting of transactions apart from trims of newlines and whitespaces. For example, conform.nvim uses bean-format for beancount files.
  • I did not find a way to sort transactions by date. I would have to do it manually.
