Configure neovim from Scratch

How to install

To install simply just type

sudo pacman -S neovim

Now make a directory in .config

mkdir ~/.config/nvim

then go to that directory and open nvim

cd ~/.config/nvim
nvim .

here this type of interface popup

How to configure

Now press : and type

:h rtp

here you can see default $XDG_CONFIG_HOME/nvim is our main directory where we put all our config files.

Now exit from that your interface should look like this

Now press % and give file name init.lua

To type something press i (insert) or a(append) type this

now exit from insert mode by pressing Esc or ctrl + c

After to save this file press : and type w(write) or wq(write and quiet)

Again go to nvim

nvim .

here you can notice that our file is created and bottom left you can see hello.

Now press d to create directory and give name lua

Go to lua directory and create a whatever named directory

And go to that directory and create file init.lua

for testing type this in your file:

Again press : to go explore mode Ex and go to previous directory ../ where our first file created

open that file ~/.config/nvim/init.lua and type this

now exit from nvim by pressing :wq

Again open nvim

pwd :- ~/.config/nvim

nvim .

A message like this will show when you open nvim

congrats if this type of message will shows so you go further and lets make nvim usable.

Creating some shortcuts

Now lets make some shortcuts first you have to create a remap.lua file in ~/.config/nvim/lua/soul/remap.lua

here vim.g.leader is name where you can assign a keybutton

in second line you can see vim.keymap.set is used for set keyboard shortcuts of vim command

here we can directly execute this command Ex by spacebar pv

save this file :w

after press :so hit Enter (it will complie the source) now you can press spacebar pv

here when you exit from nvim you have to complie again so to solve this problem we have to type this in our init.lua

pwd:- ~/.config/nvim/lua/soul/init.lua

Now you everytime you open your nvim it will compile automatically

Add pulgin-manger(packer)

Go to this repo packer.nvim

clone this repo in your ~/.config

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

Now copy this from that repo

vim.cmd [[packadd packer.nvim]]

return require('packer').startup(function(use)
  -- Packer can manage itself
  use 'wbthomason/packer.nvim'
end)

paste it in ~/.config/nvim/lua/soul/packer.lua

now complie it :so

now can able to type this :PackerSync it will look like this

if the option is not available you can restart your nvim and recomplie it .

congrats you come this far you have succesfully installed pulgin-manger.

Add Pulgin(fuzzy finder)

Now lets add some pulgin

go to repo telescope.nvim

copy this from that repo

use {
  'nvim-telescope/telescope.nvim', tag = '0.1.8',
-- or                            , branch = '0.1.x',
  requires = { {'nvim-lua/plenary.nvim'} }
}

paste in your packer.lua it should be look like this

Now press :w, :so and after that :PackerSync it will start to install that pulgin

Now copy this line paste it in ~/.config/nvim/after/pulgin/telescope.lua here create respective directory

local builtin = require('telescope.builtin')
vim.keymap.set('n', '<leader>pf', builtin.find_files, {})
vim.keymap.set('n', 'C-p', builtin.git_files, {})
vim.keymap.set('n', '<leader>ps', function()
	builtin.grep_string({ search = vim.fn.input("Grep > ")});
end)

Now press :w :so

now you can use fuzzy finder press spacebar pf or ps

Add pulgin (Rosé Pine)

Now go to this repo Rosé Pine

copy this line paste it in ~/.config/nvim/lua/soul/packer.lua

use({ 'rose-pine/neovim', as = 'rose-pine' })

vim.cmd('colorscheme rose-pine')

Now you can change it colorschema :coloschema rose-pine-main

Transparent Background

here i want traspraent background

create a file colors.lua at ~/.config/nvim/after/pulgin/colors.lua

function ColorMyPencils(color)
            color = color or "rose-pine"
            vim.cmd.colorscheme(color)
            vim.api.nvim_set_hl(0,"Normal",{bg = "none"})
            vim.api.nvim_set_hl(0,"NormalFloat",{bg = "none"})
end

ColorMyPencils()

After transparenting background . it will look beautiful ><.

Add tree sitter

Add this line in your packer.lua

use( 'nvim-treesitter/nvim-treesitter', { run = ':TSUpdate'})

Save the file :w and comple it :so and run Packer :PackerSync

copy this line and paste it in ~/.config/nvim/after/pulgin/tree-sitter.lua

require'nvim-treesitter.configs'.setup {
  -- A list of parser names, or "all" (the listed parsers MUST always be installed)
  ensure_installed = { "c", "lua", "vim", "vimdoc", "query", "markdown", "markdown_inline", "javascript", "rust", "typescript"  },

  -- Install parsers synchronously (only applied to `ensure_installed`)
  sync_install = false,

  -- Automatically install missing parsers when entering buffer
  -- Recommendation: set to false if you don't have `tree-sitter` CLI installed locally
  auto_install = true,
  highlight = {
    enable = true,
    -- Setting this to true will run `:h syntax` and tree-sitter at the same time.
    -- Set this to `true` if you depend on 'syntax' being enabled (like for indentation).
    -- Using this option may slow down your editor, and you may see some duplicate highlights.
    -- Instead of true it can also be a list of languages
    additional_vim_regex_highlighting = false,
  },
}

Save the file :w and comple it :so

Add this line in your packer.lua

use( 'nvim-treesitter/playground')

Save the file :w and comple it :so and run packer PackerSync

you can able to run :TSPlaygroundToggle

local ui = require("harpoon.ui")
vim.keymap.set("n", "<leader>a", mark.add_file)
vim.keymap.set("n", "<leader>as", ui.toggle_quick_menu)

vim.keymap.set("n", "<C-a>", function () ui.nav_file(1) end)
vim.keymap.set("n", "<C-s>", function () ui.nav_file(2) end)
vim.keymap.set("n", "<C-u>", function () ui.nav_file(3) end)
vim.keymap.set("n", "<C-i>", function () ui.nav_file(4) end)
