Why use vim and neovim over other text editors and IDEs?
For me, I’ve always loved minimalism and performance over ease of use and other flashy bloat no one really uses and cares about. This why I personally use Terminal-based text editors. Preferably VIM or Neovim. Tho I currently, am running Neovim, but both of them are basically the same. NeoVIM is a little bit more extensible than VIM and easy to manage imo. But enough talking, lets start configuring our VIM/NVIM to make it more like an actual developing environment.
IMPORTANT: Since I mainly use Neovim, some of the stuff written in this blog might not work for vim users, for them just avoid the once that are not compatible, if I find any alternatives to those plugins and setting, I will update the blogs with the details.
Step 1: Setting up the config files and directory for vim and neovim1
Follow the commands given below to make all the necessary files and directories for neovim
cd mkdir -p ~/.config/nvim touch ~/.config/nvim/init.vim
The init.vim file is the config file that we will edit in this post to make our base neovim to look and act like an actual IDE.
Step 2: Editing the init.vim file
To edit this init.vim open the file with the text editor of your choice and paste the following text
:set number :set relativenumber :set autoindent :set expandtab :set tabstop = 4 :set shiftwidth = 4 :set smarttab :set softtabstop = 4
These parameters set basic functionality for vim such as number lines, auto indentation, amd smart tabs. By default vim doesnt support mouse and its kinda normal to not use mouse since everything in vim can be done using the keyboard but if you are a soy and want to use mouse type this this too
:set mouse = a
For now we have done all the basic settings.
Step 3: Adding a Plug-In Manager
For this setup we will use Vim-Plug to manage our plugins.
apt install curl
pacman -S curl
xbps-install -S curl
Create the installation directories, download, and install Vim-Plug.
curl -fLo ~/.vim/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
Step 4: Installing Plug-ins
In your init.vim file, add these lines at the bottom of what we previously wrote.
call plug#begin() call plug#end()
We will be able to add plugins in between the two commands.
Now we will add our first plug-in
Find the desireable plug-ins from VIM Awesome this is one of the best places to find vim and neovim plugins.
For this tutorial we will add couple of plug-ins to make our neovim look good and work like an ide.
Plug 'tpope/vim-fugitive' " Git integration in to nvim Plug 'Yggdroot/indentLine' " Line Indentations Plug 'farmergreg/vim-lastplace' " Continue from where you left last time Plug 'raimondi/delimitmate' " Provides insert mode auto-completion for special-characters Plug 'tpope/vim-markdown' " Markdown runtime files Plug 'tpope/vim-surround' " Change paranthesis and quotes into other forms quickly Plug 'scrooloose/nerdtree' " File navigator Plug 'vim-scripts/indentpython.vim' " Indentation script for python Plug 'alvan/vim-closetag' " Makes a close tag for html quickly Plug 'luochen1990/rainbow' " Provides different colors to different paranthesis Plug 'airblade/vim-gitgutter' " Shows git diffs in the sign columns Plug 'lilydjwg/colorizer' " Provides color for the #rrggbb or #rgb color format in files Plug 'vim-airline/vim-airline' " Powerline Theme / Status line Plug 'vim-airline/vim-airline-themes' " Themes for vim-airline Plug 'rafi/awesome-vim-colorschemes' " Change colorschemes on the fly for vim and nvim Plug 'ryanoasis/vim-devicons' " Icons Plug 'SirVer/ultisnips' " Code completion using snippets from vim-snippets and custom snippets Plug 'honza/vim-snippets' " Provides snippets for ultisnips
First of all add few keybinding to open up NERDTree and make vertical and horizontal splits in your
nnoremap <C-f> :NERDTreeFocus<CR> nnoremap <C-n> :NERDTree<CR> nnoremap <C-t> :NERDTreeToggle<CR> nnoremap <A-h> :vsplit<CR> nnoremap <A-k> :split<CR>
After you’ve saved and exited the file now open up neovim run
:PlugInstall. This will install all the plugins in the plugged directory in
Since we installed
vim airline and
vim colorschemes we can change the look and feel of neovim/vim. Find your favorite vim colorscheme here also find your favorite airline theme here
For this blog, we will use the gruvbox theme along with the base16 airline theme. To make this permanent write these in your nvim config.
colorscheme gruvbox let g:airline_left_sep = '' let g:airline_left_alt_sep = '' let g:airline_right_sep = '' let g:airline_right_alt_sep = '' let g:airline_theme='base16'
Since we also have a plugin for autoindentation and indent lines. We have to add these lines to the config too.
let g:indentLine_fileTypeExclude = ["help", "nerdtree", "diff"] let g:indentLine_fileTypeExclude = ["help", "nerdtree", "diff", "markdown"] let g:indentLine_bufTypeExclude = ["help", "terminal"] let g:indentLine_showFirstIndentLevel = 1 let g:indentLine_indentLevel = 7 let g:indentLine_char_list = ['|', '¦', '┆', '┊']
This section is a bit tidious and is only available for neovim users so if you use vim this section is irrelevnet to you.
Add this plug-in in your init.vim file.
Plug 'neoclide/coc.nvim' " Code suggestions and completion
Now this plugin wont run without nodejs in your machine so follow these steps to make it work.
Install Nodejs and npm
apt install nodejs npm
pacman -S nodejs npm
For Other Distos and operating systems visit https://nodejs.org/en/download/package-manager/
Additional Packages Install yarn
npm install yarn
After yarn is finished installing, execute the following command
cd ~/.local/share/nvim/plugged/coc.nvim/ yarn install yarn build
Now open up an nvim install and check if any error is shown, if not then it is successfully installed. Otherwise check online for errors.
From here on out check this github repository to find your desired language to use and ways to download the language server. This is a bit tidious process but here is one example.
(EXAMPLE)Installing the python language server
- Install python3 and python3-pip
- Install jedi from the pip repository
pip install jedi
- Open up and nvim instance and run
:CocInstall coc-pythonthis will install the python module for Coc.
Follow this type of procedure to install all of your favorite language servers and have fun coding
