Vim

Vim a text editor for writing code where you navigate around the screen with a keyboard instead of a mouse it’s based on the original unix text editor vi which came about in 1976 then, vi improved or vim followed it in 1991 with a bunch of improvements

Vim is rock stable and is continuously being developed to become even better. Among its features are:

Three modes of Vim

Command mode (Where you give commands to the editor to get things done . Press ESC for command mode) Most of them below are in command mode:

x - to delete the unwanted character
u - to undo the last the command and U to undo the whole line
CTRL-R to redo
A - to append text at the end
:wq - to save and exit
:q! - to trash all changes
dw - move the cursor to the beginning of the word to delete that word
2w - to move the cursor two words forward.
3e - to move the cursor to the end of the third word forward.
0 (zero) to move to the start of the line.
d2w - which deletes 2 words .. number can be changed for deleting the number of consecutive words like d3w
dd to delete the line and 2dd to delete to line .number can be changed for deleting the number of consecutive words

Setting up Vim Configuration File

If you have like 20 settings, you don’t want to set them all the time every time you open Vim. So you want to have a settings file a configuration file that does it for you. And for that you have the VIM rc file, which is located at the user directory vi ~/.vimrc

If the file is there, vim loads it, or VIM is going to open it. If it’s not there,it will get created in VIM and Vim is still going to load it. So we’re going to open up the VIM rc file .Enter the insert mode and set the reqired settings and customize accordingly

This is just an example

set number
set relativenumber
set tabstop=3
set autoindent
set shiftwidth=4
set mouse=a
colorscheme slate

Sure! Here’s an example of explaining “Basic Vim Usage” using Markdown:

Basic Vim Usage

Opening a File

To open a file in Vim, you can use the command vim <filename> in your terminal. For example, to open a file called “example.txt,” you’d use vim example.txt.

Switching to Normal Mode

By default, Vim opens in normal mode. If you are not in normal mode, press the Esc key to switch to it.

Moving the Cursor

In normal mode, you can move the cursor using the arrow keys or these common navigation commands:

Entering Insert Mode

To start typing or editing text, you need to enter insert mode. Press i (for insert) in normal mode to switch to insert mode.

Saving a File

To save changes to the file, you need to be in normal mode. First, press Esc to ensure you are in normal mode, and then use the command :w (short for write) and press Enter. This will save the file without closing Vim.

Closing a File

To close the file and exit Vim, ensure you are in normal mode (Esc), and then use the command :q (short for quit) and press Enter. If you have unsaved changes, Vim will prevent you from exiting and prompt you to save the changes first.

Saving and Quitting in One Command

To save changes and quit Vim in one command, you can use :wq and press Enter.

Discarding Changes and Quitting

If you want to quit Vim without saving any changes, you can use :q! and press Enter. This will forcefully exit Vim without saving.

Copying and Pasting Text

In normal mode, you can copy text by moving the cursor to the start of the text you want to copy and then pressing v to enter visual mode. Move the cursor to select the desired text and press y (short for yank) to copy it. To paste the copied text, press p in normal mode.

Undo and Redo

In normal mode, you can undo changes with the u command and redo changes with Ctrl + r.
