Vim installation

Why Vim?

An indispensable text editor for backend engineers.

A text editor with extensions derived from vi.

Eclipse and VSC (Visual Studio Code) are also very nice editors.

However, it depends on the GUI environment.It is better to be able to perform simple operations.

Besides, it may look a little cool …

vim

Advanced text editor

An excellent product that allows you to quickly respond to cursor movements by switching modes with key operations.

The difficulty is that training is required until you get used to it.

vim settings

Edit the “.vimrc” file to configure Vim.

Please change the editing to your liking.

colorscheme settings

Finally, set the color scheme.

We recommend “molokai”.

Create and move directories

mkdir ~/.vim

cd ~/.vim

mkdir colors

I will clone it from git.

git clone https://github.com/tomasr/molokai

Move the clone file to the clolors directory

mv molokai/colors/molokai.vim ~/.vim/colors/

Edit vim settings

vi ~/.vimrc

Add to “.vimrc”

"colorscheme
colorscheme molokai
syntax on
let g:molokai_original = 1
let g:rehash256 = 1
set background=dark

Reopen the configuration file.

vi ~/.vimrc

good job for today. This completes the Vim installation and configuration.
