Configure Nvim with Lua: Add other features (10)

Today we going to see a some plugins that provide us with excellent features, we going to see how to configure:

• Pairings for "", ”, [], (), etc.
• Color highlighter.
• Indentation guides to all lines.
• To format code.

  cd .config/nvim

Install and configure the plugins

You can see some plugins here awesome-neovim. I selected this plugins:

• nvim-autopairs
• nvim-colorizer.lua
• indent-blankline.nvim
• null-ls.nvim

1. The first step: we add the plugins to the plugins.lua file.

  nvim lua/configs/plugins.lua

2. We add this and save it:

  -- ...others configs...
  return packer.startup(function(use)
    -- ...others plugins...

    -- Utils
    use("windwp/nvim-autopairs") -- "", '', {}, [], ()
    use("norcalli/nvim-colorizer.lua") -- colorizer the colors
    use("lukas-reineke/indent-blankline.nvim") --  adds indentation guides to all lines (including empty lines)
    use("jose-elias-alvarez/null-ls.nvim")
     -- ...others configs...
  end)

3. Install the packages:

  :PackerInstall

4. Later, we create the nvim-autopairs file.

  nvim lua/configs/nvim-autopairs.lua

5. We add this code and save it:

  local ok, nvim_autopairs = pcall(require, "nvim-autopairs")
  if not ok then
    return
  end

  nvim_autopairs.setup({
    fast_wrap = {
      map = "<M-e>",
      chars = { "{", "[", "(", '"', "'" },
      pattern = [=[[%'%"%)%>%]%)%}%,]]=],
      end_key = "$",
      keys = "qwertyuiopzxcvbnmasdfghjkl",
      check_comma = true,
      highlight = "Search",
      highlight_grey = "Comment",
    },
  })

6. We create the nvim-colorizer file.

  nvim lua/configs/nvim-colorizer.lua

7. We add this code and save it:

  local ok, colorizer = pcall(require, "colorizer")
  if not ok then
    return
  end

  -- you can add other filetypes
  colorizer.setup({
    "scss",
    "css",
    "html",
    "javascript",
    "typescript",
    "svelte",
    html = {
      mode = "foreground",
    },
  })

6. We create the indent_blankline file.

  nvim lua/configs/indent-blankline.lua

7. We add this code and save it:

  local ok, indent_blankline = pcall(require, "indent_blankline")
  if not ok then
    return
  end

  indent_blankline.setup({
    show_current_context = true,
  })

8. We create the null-ls file.

  nvim lua/configs/null-ls.lua

9. We add this code and save it:

  local ok, null_ls = pcall(require, "null-ls")
  if not ok then
    return
  end

  local formatting = null_ls.builtins.formatting
  local augroup = vim.api.nvim_create_augroup("LspFormatting", {})

  null_ls.setup({
    sources = {
      formatting.stylua,
      formatting.prettier.with({
        filetypes = {
          "html",
          "json",
          "yaml",
          "markdown",
          "md",
          "svelte",
          "javascript",
          "typescript",
          "css",
          "scss",
        },
      }),
    },
    -- you can reuse a shared lspconfig on_attach callback here
    on_attach = function(client, bufnr)
      if client.supports_method("textDocument/formatting") then
        vim.api.nvim_clear_autocmds({ group = augroup, buffer = bufnr })
        vim.api.nvim_create_autocmd("BufWritePre", {
          group = augroup,
          buffer = bufnr,
          callback = function()
            vim.lsp.buf.format({ bufnr = bufnr }) -- this is for 0.8v
            -- vim.lsp.buf.formatting_sync() -- you should use this for 0.7 or minor
          end,
        })
      end
    end,
  })

• In my case only use formatting for lua and prettier. You should install this:

• For Lua (you can review how install this package in your OS):

  brew install stylua

• For prettier:

  npm install -g prettier

10. To use these settings, we need to call the configurations files in the main file (init.lua)

  nvim init.lua

• Add this:

  -- ...
  require("configs.nvim-autopairs")
  require("configs.nvim-colorizer")
  require("configs.indent-blankline")
  require("configs.null-ls")

And that’s it!! You have already configured other functionalities. Now, you can enjoy greater comfort when working.

Directory

We have the directory of folders like this:

nvim
├─ init.lua
└─ lua
  └─ configs
    └─ options
    |   └─ init.lua
    └─ keymaps.lua

Conclusion

In this article we learned how to install and configure the plugins to improve our comfort when working.
