Introduction

When I saw a YouTube video about live coding where vimmer code, I was amazed at the speed of coding.
This article is a record until I became a Vimmer.

Prerequisite

This article was inspired by this
Using Macbook
Using Iterm2

Install Packer

What is Packer

Packer is a plugin manager written by Lua.

How to set up

Clone packer in your pc

git clone --depth 1 https://github.com/wbthomason/packer.nvim\
 ~/.local/share/nvim/site/pack/packer/start/packer.nvim

Create ~/.config/lua/plugins.lua
I write plugins in ~/.config/lua/plugins.lua.

cd .config && mkdir nvim && cd nvim
mkdir lua
nvim lua/plugins.lua

local status, packer = pcall(require, "packer")
if (not status) then
  print("Packer is not installed")
  return
end

vim.cmd [[packadd packer.nvim]]

packer.startup(function(use)
  use 'wbthomason/packer.nvim'
  -- Your plugins go here
end)

Create ~/.config/nvim/init.vim

require "plugins"

~/.config/nvim/init.vim is Neovim configuration file for Neovim(.vimrc in vim).

Colorschema

I'm using [Neosolarized].(https://github.com/svrana/neosolarized.nvim)
Add plugin in ~/.config/lua/plugins.lua

require('packer').startup(function(use)
  use 'wbthomason/packer.nvim' -- The packer plugin manager itself
  -- Your plugins go here
  use 'tjdevries/colorbuddy.nvim'
  use 'svrana/neosolarized.nvim'
end)

'tjdevries/colorbuddy.nvim' is neseccary to use Neosolarized.

Run :PackerInstall
This command install Neosolarized

Setup Neosolarized in ~/.config/after/plugin/neosolarized.lua
after/plugin directory was loaded after loading specific plugins.
This is useful when we customize plugins.
I copied this code.

Enable termguicolors
This is neseccary to use Neosolarized.
By default Iterm2 can only use 256 colors, but "Neosolarized" uses more than 256 colors.

Status line

I'm using lualine.nvim

Add plugin in ~/.config/lua/plugins.lua

packer.startup(function(use)
  use 'wbthomason/packer.nvim'
  -- Your plugins go here
  use 'svrana/neosolarized.nvim'
end)

Run :PackerInstall

Setup Lualine in ~/.config/after/plugin/lualine.lua
I copied this code.

Tab

I'm using [Bufferline].(https://github.com/akinsho/bufferline.nvim)
Add akinsho/bufferline.nvim in ~/.config/lua/plugins.lua
**Setup Bufferline in after/plugin/bufferline.lua

local status, bufferline = pcall(require, "bufferline")
if (not status) then return end

bufferline.setup({
  options = {
    mode = "tabs",
    separator_style = 'slant',
    always_show_bufferline = false,
    show_buffer_close_icons = false,
    show_close_icon = false,
    color_icons = true
  },
  highlights = {
    separator = {
      guifg = '#073642',
      guibg = '#002b36',
    },
    separator_selected = {
      guifg = '#073642',
    },
    background = {
      guifg = '#657b83',
      guibg = '#002b36'
    },
    buffer_selected = {
      guifg = '#fdf6e3',
      gui = "bold",
    },
    fill = {
      guibg = '#073642'
    }
  },
})

vim.keymap.set('n', '<Tab>', '<Cmd>BufferLineCycleNext<CR>', {})
vim.keymap.set('n', '<S-Tab>', '<Cmd>BufferLineCyclePrev<CR>', {})
