LTeX language server provides some code actions off the LSP specifications. These commands require client implementations for things like file system operations.

LTeX_extra is a companion plugin for LTeX language server that provides such implementations for Neovim. The current supported methods are: addToDictionary, disableRule, hideFalsePositive.

Installation

🚧 This plugin will be rewritten and as consequence I want to support just one method to initialize the plugin. The chosen one probably will be based on the LspAttach autocommand. I won't support the server initialization through this plugin anymore. It was a bad decision, doesn't provide much value and is hard to maintain.

This plugin requires an instance of ltex_ls language server available to attach. ltex-ls is available at mason.nvim.

Install the plugin with your favorite plugin manager using {"barreiroleo/ltex-extra.nvim"}. Then add require("ltex_extra").setup() to your config.

There are two recommended methods:

1. Call the setup from on_attach function of your server. Example with lspconfig, minor changes are required for mason handler: lua require("lspconfig").ltex.setup { capabilities = your_capabilities, on_attach = function(client, bufnr) -- rest of your on_attach process. require("ltex_extra").setup { your_opts } end, settings = { ltex = { your settings } } }

2. Use the handler which ltex_extra provide to call the server. Example of use with lazy.nvim:

   return {
      "barreiroleo/ltex_extra.nvim",
      ft = { "markdown", "tex" },
      dependencies = { "neovim/nvim-lspconfig" },
      -- yes, you can use the opts field, just I'm showing the setup explicitly
      config = function()
          require("ltex_extra").setup {
              your_ltex_extra_opts,
              server_opts = {
                  capabilities = your_capabilities,
                  on_attach = function(client, bufnr)
                      -- your on_attach process
                  end,
                  settings = {
                      ltex = { your settings }
                  }
              },
          }
      end
   }

Configuration

Here are the settings available on ltex_extra. You don't need explicit define each one, just modify what you need.

Notes: You can pass to setup the arguments that you are interested in and omit the rest. At the moment, if you have dictionary, disabledRules and hiddenFalsePositives defined in your ltex settings, they aren't backed up.

require("ltex_extra").setup {
    -- table <string> : languages for witch dictionaries will be loaded, e.g. { "es-AR", "en-US" }
    -- https://valentjn.github.io/ltex/supported-languages.html#natural-languages
    load_langs = { "en-US" } -- en-US as default
    -- boolean : whether to load dictionaries on startup
    init_check = true,
    -- string : relative or absolute path to store dictionaries
    -- e.g. subfolder in the project root or the current working directory: ".ltex"
    -- e.g. shared files for all projects:  vim.fn.expand("~") .. "/.local/share/ltex"
    path = "", -- project root or current working directory
    -- string : "none", "trace", "debug", "info", "warn", "error", "fatal"
    log_level = "none",
    -- table : configurations of the ltex language server.
    -- Only if you are calling the server from ltex_extra
    server_opts = nil
}

FAQ

Force reload

If you experience hangs with the server/plugin, you can force a reload of the LTeX files by running require("ltex_extra").reload()

Lspsaga:

Some users of lspsaga has reported issues with code actions. I don't use lspsaga, so PRs are welcome. Just make sure to test without that plugin enabled as well.
